Case Study – Impressive SolarEdge Solar PV System and EV charger
Case Study – Impressive SolarEdge Solar PV System and EV charger 560 747 Elektra Smart Energy
 
Impressive SolarEdge Solar PV System and EV charger

I would like to share with you our experience on one of our projects that was a Particularly impressive outcome.  We installed a SolarEdge system complied with ‘all black’ panels and bird protection.

Initially the client requested we install 32x N-Type ‘All Black’  435W Jinko Solar panels,  just under 14kW Solar PV system. After a G99 application we received export limitation from the DNO so we  agreed with the client to reduce the system to 9.1kW.

We installed 21 N-Type ‘All Black’ 435W Jinko Solar panels. These panels look smart and include the latest N-type technology and come with a 25-year product warranty and 30-year performance warranty.

The Solar Panels we Installed
What is N-Type technology?

N-type ( “negative-type”) solar PV panels have several advantages over other types of solar panels, such as P-type (P-type meaning “positive-type”). Here are some of the advantages of N-type solar panels:

Higher Efficiency: N-type solar panels typically have higher efficiency compared to P-type panels. Higher efficiency means that they can convert a greater percentage of sunlight into electricity, leading to a better overall performance.

Lower Degradation Rates: N-type solar cells often exhibit lower degradation rates over time. The efficiency of N-type panels tends to degrade slowly compared to other types, so a longer lifespan and more stable performance over the years.

Better Performance in High Temperatures: N-type solar panels generally perform better in high-temperature conditions. They are less sensitive to temperature-related efficiency losses, which is an important factor in regions with hot climates.

Lower Light-Induced Degradation (LID): N-type solar cells are less prone to a phenomenon known as Light-Induced Degradation . Can lead to a temporary decrease in efficiency of solar panels when exposed to sunlight for the first time. N-type cells experience less LID compared to P-type cells.

Higher Voltage Output: N-type solar cells typically have a higher voltage output, which can be advantageous in certain system configurations. Higher voltage can reduce the overall system losses and improve the overall performance of the solar power system.

Lower Sensitivity to Impurities: This reduced sensitivity can contribute to better overall stability and reliability of N-type solar panels.

Important to note that choice between N-type and P-type solar panels depends on various factors, cost, availability, specific application requirements. Advances in technology and manufacturing processes may continue to influence the relative advantages of different types of solar panels.

As part of the SolarEdge System we installed optimisers- one optimiser to each Solar PV panel

Diagram of an Optimiser

What is an Optimiser and why do we need it?

A SolarEdge optimiser is a device used in photovoltaic (PV) solar power systems to maximize energy harvesting from solar panels.

They perform several functions:

Maximum Power Point Tracking (MPPT): Optimisers enable each panel to operate at its optimal voltage and current (maximum power point)

Shade Tolerance: SolarEdge optimisers allow unaffected panels to continue operating at peak efficiency

Monitoring and Safety: SolarEdge optimisers provide real-time monitoring.

Design Flexibility: SolarEdge design flexibility allows the installation of panels with different orientations, tilts, or different types on the same string

In summary:

SolarEdge optimisers enhance overall performance, efficiency, safety of solar power systems by optimising the output of each individual solar panel. Not every solar installation requires optimisers, they are particularly beneficial where shading, panel mismatch, or variable environmental conditions are prevalent

We installed a SolarEdge 10kWh single phase inverter for any future expansion with 20kWh batteries. It gave the client the following benefits:

    • During sunny days the client is able to store up to 20kWh of electricity in the battery  to be used at night when the Solar PV doesn’t generate electricity with no or very minimal use of electricity from the grid.

    • During cloudy days where the Solar PV doesn’t provide enough electricity required, the battery can be charged during the night-time at night’s tariff, which is 25% of the cost of day’s tariff to be used in the daytime.  This is called Energy arbitrage – meaning storing energy for use during pick hours guarantees much cheaper electricity prices throughout the day.

     

    For more info about optimisers: Click here

    We also installed a bird blocker

    A “solar PV bird blocker” refers to a device or system designed to prevent birds from nesting or perching on solar photovoltaic (PV) installations. Birds can sometimes pose issues for solar panels by leaving droppings that reduce efficiency, scratching or pecking at the panels,  nesting in the areas around the panels  and increases risk of fire. 

    Whilst there are several solutions and systems offered in the market to block birds from going under the solar panels, we believe placing a screen around the solar array is the more efficient solution.

    In this project we used a ‘BirdBlocker’ system, which offers 99% certainty that bird will not go under your array and made of 100% recyclable material. This system also come with 10 year warranty.  

    For more information on BirdBlocker: Click here

     

    The BirdBlocker we Installed

    Finally, we installed a Smart EV charger, unfortunately SolarEdge are yet to launch their EV charges in the UK, which would be the ideal EV charger to work with the Solar Edge. However, in this case we installed a Smart Ratio EV charger with additional CT to monitor the load and reduce the risk of the EV charger draining the Solar PV batteries. The Ratio EV charger is a very smart charger, in addition to the Dynamic Load Balancing functionality, it can charge your EV using 100% free energy generated from the home Solar PV system.

    Solar Savvy: Is Your Roof a Good Candidate for Solar Panels?
    Solar Savvy: Is Your Roof a Good Candidate for Solar Panels? 560 747 Elektra Smart Energy

    Solar panels are gaining popularity as homeowners seek out more ways to lower their energy expenses and environmental effect.

    Here are a few factors to consider:

    Age:

    One thing to keep in mind is how old your roof is. Replacing your roof before installing solar panels if it is getting close to the end of its useful life. By doing this, you can make sure that your roof can support the solar panel system and avert future problems. Specific age limit depends on various factors, roofing material, climate, how well the roof has been maintained over the years. While there is no strict age limit for installing solar panels, it’s generally recommended that your roof should have at least 10-15 years of life remaining to make the investment worthwhile, since solar panel systems typically have a lifespan of 25-30 years and it can be costly and disruptive to remove and reinstall the system if you need to replace your roof during that time.

    Condition:

    Look for any indications of damage on your roof, such as broken or missing shingles, leaks, or other structural problems. It’s critical to take care of any damaged roof components before adding solar panels. Using binoculars if needed, begin by visually inspecting your roof from the ground. Keep an eye out for any overt indications of damage, such as missing or damaged shingles, buckling or curling shingles, granules in the gutters, or other visible issues. You can also go into your attic and inspect the underside of the roof for any signs of water damage, such as staining, mould, or rot. Also, look for any signs of light coming through the roof, which could indicate a hole or other damage.

    Material:

    Asphalt shingles, metal roofs, and flat roofs are generally good candidates for solar panel installations. However, slate, clay, and wood shake roofs may be more challenging and require additional considerations. Work with a professional solar installer who has the knowledge and expertise.

    Before installing solar panels, check the warranty on your roof. Review the terms and conditions of your warranty and discuss any concerns with your solar installer. If your roof warranty does now allow for solar panel installations, there are a few options you can consider.
    • Reach out to the roofing manufacturer to see if they can provide any guidance or exceptions. They may be able to work with you to find a solution that allows for solar panel installations without voiding your warranty.
    • Some solar panel mounting systems do not require drilling into the roof, which can help avoid voiding your roof warranty. Ballasted or non-penetrating mounting systems use weights or other methods to secure the solar panels to the roof without penetrating the roofing material. Consult with a solar installer to see if this is a viable option for your situation.
    Orientation:

    The pitch and orientation of your roof can also impact its suitability for solar panels. South-facing roofs with a pitch between 15 and 40 degrees are typically ideal for solar panel installations. However, solar panels can still be effective on roofs with different orientations and pitches, so it’s important to consult with a solar installer to determine the best solution for your specific situation.

    Shading:

    Trees, chimneys, and other structures can cast shadows on your roof, reducing the effectiveness of your solar panels. It’s important to assess the amount of shading on your roof and consider trimming or removing any obstacles that may block the sun. There are several online tools and apps available that can help you assess the shading on your roof. These tools use satellite imagery and other data to provide a rough estimate of the shading on your roof. It may also be helpful to consult a professional solar installer who can conduct a thorough shading analysis of your roof using specialised equipment and software. They can provide you with a detailed report on the shading on your roof and recommend the best placement for your solar panels.

    Local regulations and incentives:

    Some areas have regulations or incentives that can impact the feasibility and cost of installing solar panels. Check with your local government and utility company to see if there are any restrictions or incentives in your area. For more information, read our blog post about the grants and funding currently available in the UK.

    If installing solar panels on your roof is not feasible, you may want to explore other solar options, such as ground-mounted solar panels or solar carports. A professional solar installer can assess your specific situation and provide recommendations on the best course of action. They can help you explore your options and determine the most cost-effective and feasible solution for your situation.

        Why are Energy Prices so High?
        Why are Energy Prices so High? 560 747 Elektra Smart Energy
        The energy price cap is determined by the energy industry regulator, Ofgem and the cap sets a maximum price that energy suppliers can charge customers for each kilowatt hour (kWh) of energy that they use.  

        After a 54% increase to the energy price cap in April 2022, the Energy Price Guarantee (EPG) was enforced .

        This was a great reduction from the energy price cap level of £3,280 set by Ofgem.  

        What caused the Energy Crisis? 

        Our energy bills have been increasing due to supply and demand issues pushing up wholesale energy prices. This is the amount that your provider pays to the energy generators for gas and electricity. It is the rise in these wholesale costs that are the main driver in the energy price spikes. So, what has caused the wholesale prices to rise?  

        Peruvian imports have also more than doubled.

        Sellindge. This is the European link combining the technical expertise of both the British National Grid and the French RTE. The site is still not running at full capacity, and is aiming to reach this goal by October 2023.  

        Why are Energy Bills still so high? 

        Our bills are dependent on the wholesale prices of energy, which are now decreasing. Network cost, which makes up 25.35% of our energy bills, pays for fitting and running gas pipes and electricity cables. It also covers the cost of energy firms that have failed. Our energy bills are therefore entirely dependent on the price of imports. As a result, most companies “hedge”.

        Will Energy Bills stay down? 

        Market analysts do predict that energy prices will continue to decrease from 2023 into 2024. This may spark competition within the industry, pushing prices down further.

Lithium and cobalt are two key components and are becoming the most valuable commodities on the planet. As finite materials, depleted when used. This poses the question; could hydrogen fuel cells demonstrate a more sustainable future for the car industry? 

        So how does a hydrogen fuel cell work?

        • Contains a fuel tank that stores hydrogen in its gas form, since liquid hydrogen requires cryogenic temperatures (-253°C).
        • It combines hydrogen and oxygen in a chemical reaction that generates electricity.
        • It is used to power the vehicle, with water vapour as the only waste product.
        • Since hydrogen is the most abundant element in the universe, hydrogen fuel cells are a completely renewable energy source. They have no polluting outputs, but hydrogen is present in nearly all molecules in living things.
         
        hydrogen fuel cells

        Over 90% of hydrogen fuel produced currently comes from fossil fuels. Natural gas is reacted with high-temperature steam for synthesis gas. Carbon monoxide is reacted with water to produce additional hydrogen. This method is the cheapest, most efficient. It is a common way to obtain hydrogen, but the hydrogen generated only holds around 75% of the energy used to produce it. This means it costs more energy to obtain hydrogen than it will generate when reversed in the fuel cell. Carbon dioxide and carbon monoxide are two greenhouse gases. They are also waste products of this technique, consequently rendering natural gas reforming a highly inefficient and counterintuitive procedure. 

        Alternatively, electrolysis of water uses an electric current to split water into hydrogen and oxygen. If electricity is produced by renewable sources, solar or wind, the hydrogen is entirely renewable. This procedure seems faultless in theory, but it does not quite work in practice. With current technology, conventional electrolysis produces hydrogen at only 75% efficiency. We can investigate this efficiency further, noting the hydrogen requires storage in a high-pressure tank. A study by the European Federation for Transport and Environment, found storage of hydrogen at such high pressure requires 40% of the energy stored in the fuel itself. The most efficient hydrogen-fuel cells then convert the stored hydrogen into electricity.  It powers the electric motor of the car with 60% efficiency. This motor is then 95% efficient. Only 25% of the initial energy produced at the power station is converted into the motion of your car.  
        The important comparison between electric vehicles and hydrogen fuel cells. Electricity is easier and more efficient to transport than hydrogen and uses existing infrastructure to do so. After transportation, it is significantly more efficient to Retrieve energy from batteries than to convert it in a fuel cell. Electricity travels through existing power lines with 95% efficiency. Charging a lithium battery is 90% efficient. Using the power from that battery in an electric motor is around 95% efficient. Approximately 73% of the initial energy produced at the power station is converted into the motion of your car. This is almost three times more efficient than the hydrogen fuel cell.  

         

        Comprehending that both the electric battery, and the hydrogen fuel cell are just methods to deliver electrical energy to an electrical motor. The battery stores this electricity directly and efficiently for use. The fuel cell requires a chain of processes, that each use up a part of the energy along the way. A hydrogen car will not prove environmentally sustainable until the energy required to produce and transport the hydrogen can be generated purely and much more efficiently through renewable techniques.  
        On a day-to-day level, with only 15 hydrogen filling stations, compared with 43,626 electric vehicle charging points, across the United Kingdom, hydrogen is not a practical option for many of us looking to use our vehicles regularly for work and leisure. Most automakers have shifted their focus towards electric vehicles, with only Toyota and Hyundai producing hydrogen fuel cells for the UK. Both Toyota and Hyundai’s models are expensive to buy, with the Hyundai Nexo priced at around £70,000 and the Toyota Mirai at £50,000. Furthermore, once you’ve bought the car, the running costs are currently higher than for a conventional or electric car. In the UK, hydrogen fuel ranges from £10 to £15 per kg, meaning that it will cost around £11.40 to cover 100km, compared with £7.48 for petrol, £6.76 for diesel, and just £2.79 to charge an electric vehicle to cover this distance.  
        So why talk about hydrogen fuel cells at all? 

        There is extensive debate over whether there is enough lithium and cobalt locked inside igneous rock formations and saltwater brine to meet the demand of an electric car revolution. Hannah Ritchie, a data scientist at Oxford University, examined this question in detail. Although the earth hosts approximately 88 million tonnes of lithium, which is enough to supply electric vehicles for decades into the future, only 25% of this is economically viable to mine. Ritchie found that these reserves would be enough to power 2.8 billion EVs, compared with the 1.4 billion cars on the road at present. Likely to increase with innovations and developments in mining and battery technology. Nevertheless, Ritchie’s estimations also showed that an electrified economy by 2030 would require between 250,000 to 450,000 tonnes of lithium, compared to the 105 tonnes of lithium produced worldwide in 2021. This is the major obstacle of the electric vehicle revolution:

        How do we increase our lithium production by 250,000%, and fast?

        Renewable Energy Grants
        Renewable Energy Grants 560 747 Elektra Smart Energy

        With energy bills at an all time high, you may be looking into renewable energy options for your home. Here is an overview of all the possible renewable energy grants and funding options

        Energy Company Obligation (ECO4) Scheme

        ECO4 is the latest phase of the ongoing government scheme to support low-income households by funding energy-efficient upgrades to homes, It requires that large energy companies (such as EDF, British Gas, Scottish Power etc.) pay to have energy-saving measures installed in people’s homes.

        ECO4 – install solar photovoltaics (PV) in all electrically heated homes. If Biomass machine or District Heat Network are ruled out.

        Who is eligible for the scheme?

        ECO4 is available to:

        • Homeowners, landlords and private tenants
        • People receiving income-related benefits
        • Properties with inefficient electric heating, within the D-G energy efficiency band.

        Qualifying benefits for the ECO4 scheme include:

        • Jobseekers Allowance (JSA), income based
        • Employment and Support Allowance (ESA), income related
        • Housing Benefit
        • Pension Credit
        • Income Support (IS)
        • Universal Credit (UC)
        • Work Tax Credit (WTC)
        • Warm House Discount Scheme Rebate
        • Child Tax Credits
        • Child Benefit, depending on income threshold

         

        The LA Flex Scheme

        If you are not receiving any benefits, you may still qualify for funding through the LA Flex Scheme. This is an extension of ECO4

        Who is eligible for the scheme?

        Although  criteria can vary between councils, LA Flex is  targeted at two groups of people who are on low incomes:

        1. Those that are in fuel poverty (households spending at least 10% of their net income on heating their home)
        2. Those who are more vulnerable and at risk during cold weather including:
        • People with cardiovascular conditions
        • People with respiratory conditions
        • People with disabilities
        • People with mental health conditions or learning disabilities that lowers the individual’s ability to look after themselves (including those with dementia)
        • Older people (age 65 and over)
        • Households with young children (0-5)
        • Pregnant women
        renewable energy grants

         

        The Green Deal Scheme 

        The Green Deal helps you make energy-saving improvements to your home through a loan which you’ll have to pay back.  One of the most accessible renewable energy grants, any household with an electricity meter (including prepayment meters) can use the scheme, as long as both the landlord and the tenant agree to the improvements if the building is rented. You must get your property assessed by a qualified Green Deal assessor to use the Green Deal, who will visit your home and talk to you about your property and your energy use to help decide if you could benefit from Green Deal improvements, such as solar photovoltaic (PV) panels. You will then receive a Green Deal advice report which is valid for 10 years, or until you make changes or energy saving improvements to the property, for example you build an extension or change the windows.  

        A finance plan can then be offered to you by a Green Deal provider for improvements recommended in your Green Deal assessment, which will be based on what you’ll be expected to save on your energy bills. The annual repayments on the loan should therefore not be more than the savings you might make on your energy bills.  

        The loan differs to a usual loan, as it will be paid back through a charge added to your electricity bill. This is because the Green Deal stays with the property. If you decide to move, you no longer benefit from the improvements and therefore you stop paying for them.  

        The Smart Export Guarantee (SEG) Scheme 

        Instead of offering renewable energy grants directly; the SEG scheme delivers a solution to reimburse your investment. The scheme requires energy suppliers with over 150,000 customers to pay homeowners for unused solar-generated electricity, feeding any unused electricity from your solar photovoltaic (PV) panels into the National Grid. Under SEG, you will get paid for every unit of electricity that you give back to the grid.  

        Who is eligible for the scheme?
        1. You must install a renewable electricity-generating system (such as solar panels)
        2. You will need a smart reader, since you’ll need to provide half-hourly export readings
        3. Your installation and installer should be certified through the Microgeneration Certification Scheme (MCS)
        Pay 0% VAT on ‘energy-saving products’ until March 2027 

         VAT on ‘energy-saving products’ will be set at 0%,  a significant reduction from the previous rate of 5% and the typical charge of 20%. Eligible parties will be reliant on installers and suppliers to qualify for this reduction. Products can not be bought or installed DIY. 

        If the cost of the products (not including VAT) is 60% or less of the total cost of the installation (not including VAT), you’ll pay 5% on everything. If the products cost more than 60% of the total cost of installation, homeowners will pay 5% VAT on the labour and the standard rate of 20% for the products.

        Thorlux Lighting introducing a new EV charging
        Thorlux Lighting introducing a new EV charging 768 1024 Elektra Smart Energy

         

         

        For over 20 years we have worked with Thorlux Lighting.  Thorlux have entered into the EV charging industry with their new Ratio brand and the products are very exciting. 

        There are currently two Ratio products available.

        The io5 home charger and the io7, a lighting bollard incorporating a built in EV charger

        Ratio io5 – A slick product which connects to the cloud via wi-fi or an ethernet connection and controlled via the Ratio app.  The app enables the user to set timings, and measure and report usage to take advantage of low-cost tariffs. The optional sensor box allows for dynamic load management, maximising power delivery.

        Integrates with solar panel. Four io5 chargers connect to the same supply shares available power. It comes in a range of models and cables to suit all your needs. 

        The Ratio io5 is fully compliant with UK government regulations and OZEV approved. Dynamic load management guarantees the available energy capacity from your home connection. Distributed in the best way possible, and app control eliminates unauthorized usage. The PEN fault detection function ensures protection during the charging process and is without the installation of an earth rod.

        The design of this charger makes for simple and practical charging and saves you valuable time.  The unit is compatible with all new electric vehicles and the plug and go design enables easy control from your mobile phone. Supplied as 7.4kW single phase or 22kW three phase.

        Ratio io7 – The lighting bollard consists of a high performance built-in illuminated head and EV chargers.  The sophisticated LED optic provides excellent high light uniformity. Ground illumination can be incorporated into any exterior lighting solution.

        The io6 introduced in July -August 2023  is a home charger and it is similar to the io5 in style but will also include some key differences :

        •  RFID Reader-Vast majority of businesses want to know who is using the chargers, and may want to re-charge these people via payroll, RFID enables this simply without using the app.
        • 4G Option-Most homes are happy to connect via Wi-Fi, but businesses are often reluctant to use it and they would prefer the 4G option. They don’t then need to worry about the security of their network.
        • OCPP compliant-Most businesses will want the option of a back-office for support and information.

         

         

        Here at Elektra Smart Energy, we are very excited with these products and are very much looking forward to working alongside Ratio in the future and continuing our excellent working relationship. For more information about the Ratio range please visit www.ratioev.uk

        Case Study – EV charger install
        Case Study – EV charger install 560 747 Elektra Smart Energy

         EV charger install

        The Enquiry

        A potential client enquired about an EV charger installation. They had already been in touch with several companies who were overpriced or didn’t  respond.   The installation was challenging and not what some companies would call a ‘standard installation’!🤔

        Firsty  we carried out a site survey & client meeting to identify their requirements and the details of the existing installation.

         The Options

        The client had 2 options in mind for the location of the EV charger . One being a fairly simple installation that would be cheaper but we thought it would be a compromise for the convenience of the client to use.   So after careful consideration & discussion we agreed the more difficult option was the best way forward for our client.  We also advised on the most appropriate charge unit based on the clients wants & future proofing.

         The Choice

        The position chosen was almost as far away from the supply connection point as it could be 🙈. The cable also needed to be hidden as much as possible.  A trench was not possible due to underground services and the costs involved.

        We made the application to the electricity supplier (DNO) on behalf of the client.

        The main challenge

        The cable run between the supply & the charger position.

        The property is a traditional stone cottage that has had various additions and alterations over the years.  Therefore due to the aesthetics of the property an external surface installation could not be justified.

        The route proved challenging not only from a design perspective but also from a physical one. The engineers found themselves in a tight squeeze in various lofts spaces where the original building joined the new extension and came across all sorts of hidden services within the new extension!

        The Result

        Although the project was not straight forward, we managed to provide the client with the best solution for their needs & budget and at the same time kept the integrity of the property by providing a discreet installation as far as was practicable.

        A great job by the guys yet again👍
