Mrs. Whetter

Home Solar Install

"So where to start, maybe at the beginning, i decided that now was the right time to start to look at solar PV systems with a view to installing and therfore reduce my electricity consumption. I did some research so had ian idea of what i would like. I did the usual thing of going out to get multiple quotes , but Guy was the only one to consider suggestions and options that i felt were most approrpriate for my needs and usage. tick, thats obvisouly a winner. We agreed a spec and a couple of weeks later the install started, the weather didnt help with this, but at no time did this delay to a point that i felt i was being pushed down the priority list. Constant questions and information were exchanged during this time so that i knew, and they knew what  was going to be comformtable with. Attention to detail was top notch even to the point that if something need to be re started to get it 100% it was, rather than it being good enough. There have been some initial teething issues, which have been resolved as quick as can be expected, especially when having to deal with 3rd party infrastructure suppliers. Would i promote GreenSwitch, of course, would i refer then to my friends, family and neighbours, definately and have already started down that road. Do i feel iwill get support going forward if i need it, yup. 5 stars all the way."

Home Solar and Battery Install

"Smashing.  We wanted to add battery storage to our existing set up of solar panels and myenergi Zappi electric car charger, and Guy was able to recommend and install the myenergi Libbi 10w system.  All done in a day including a replacement fire-resistant mounting board and replacing our existing solar inverter with a myenergi hybrid one that could talk to the batteries.Guy explained everything and was very focused as he worked - he also tidied up and even took the packaging.It seems to me that the green technology of solar/battery/car has really come into its own recently (and so have the matching energy company tariffs) and Guy is well up to speed with all the latest developments.  If you're thinking about investing in a system of your own I would contact Guy and see if he can suggest something to suit your needs and budget - it will be honest.I heartily recommend Guy with no hesitation, it's a shame that we didn't need more work done!"

More questions about solar panel installation?

How much value will solar provide?

Installing a solar panel and battery storage system to your house can provide financial, environmental, and practical benefits. It can lower energy bills, offer energy independence, increase your EPC rating, reduce your carbon footprint, and provide backup power. However, the exact value added depends on various factors such as system size, local energy costs, and real estate market conditions.

How much power will I get?

The power output of a solar panel install is influenced by factors such as system size, geographic location, panel efficiency, installation angle and orientation, shading, and battery storage capacity. Each of these factors can impact the overall energy production of your system. To get an accurate estimate of the power output for your specific situation, it's best to consult with a solar energy expert who can evaluate your needs and provide a customized assessment, taking all of these factors into account for optimal system design and performance.

What impact will my system have?

The positive impact of solar energy installation and battery storage, is extensive and includes reduced greenhouse gas emissions, lower carbon footprints, decreased reliance on fossil fuels, and less strain on the grid. Solar energy generates no greenhouse gas emissions, saving over 900kg of CO2 per year with a typical solar panel, which helps combat climate change. By utilising these systems, households and businesses can promote a more sustainable and eco-friendly lifestyle. These installations also support the renewable energy sector, encourage a shift away from non-renewable energy sources, and conserve finite resources, ultimately contributing to a more sustainable future and a healthier planet. Additionally, solar panel systems with battery storage reduce the overall demand for electricity from the grid, particularly during peak hours, alleviating pressure on grid infrastructure and decreasing the need for fossil fuel-based power plants or grid upgrades.

How long does it take?

The process of solar panel install and battery storage system begins with an on-site survey and quotation, which typically takes 1-2 hours to complete. During this stage, a professional solar installer will assesses the property, discusses the client's requirements, and provides a detailed quote for the project. If the customer is happy with the selected system, the next step is to obtain the relevant permissions, if necessary, to ensure all required permits and approvals are in place for the project. Following the survey, quotation, and permission stage, the actual installation of the solar panels and battery storage system takes about 2-4 days, depending on factors such as the size and complexity of the system, site-specific conditions, potential challenges that may arise, and unforeseen circumstances like adverse weather conditions.Once the installation is complete, the handover process begins. This involves signing off on the work, registering warranties, and providing a comprehensive explanation of the system to the customer. The handover process ensures that the customer is satisfied with the system and understands how everything works. After the handover, the grid notification takes place, which can take up to a 10 days for the paperwork to come through. Overall, the entire process of installing a solar panel and battery storage system, from the initial survey and quotation to the final handover and MCS certification, can take anywhere from a few days to a few weeks, depending on various factors and circumstances.
