Generate free clean energy, save money on your electricity bills, protect yourself against rising electricity rates in the future reduce your carbon footprint, protect the environment.
Any excess energy you produce will be sold back to the grid.
This can be claimed back via SEG (Solar Export Guarantee)
Yes, solar panels produce electricity even on cloudy days.
Yes, solar panels do work without the need for battery storage. The addition of battery storage allows you to use more of the energy you generate in your home rather than exporting it back to the grid.
Most manufacturers offer warranties between 25 to 30 years solar panels will still work after that at a reduced capacity.
South facing roofs are best. Solar panels on East facing or West facing roofs will still perform well.
Solar panels are generally self-cleaning, reducing the need for them to be cleaned.
However it is often advised to clean them once a year.
Solar battery storage is often installed in a garage, utility room or cupboard or similar as it must be close to your consumer unit.
Most battery systems can be fitted in a loft as battery advancements have reduced the weight.
There’s so many different configurations of solar panels in the UK, that it’s almost impossible to guess the price of a system, without finding our exactly what would work for your home.
The Feed-in-Tariff ended on the 31st of March 2019, this has now been replaced with newer, smarter grid-trading solutions that allow you to sell your surplus energy across the grid.
Solar PV systems feature an array of cells which contain a solar PV material that can convert radiation from the sun into direct current (DC) electricity. The electricity that is generated can be used to provide power for lighting and electrical equipment around the home.
The more solar panels you have installed, the more energy they’ll be able to generate for your home. The number of solar panels you’ll need will depend on your energy usage, the number of people in your home and the size of your property. Smaller homes might need a 1kW system, while higher demand can be met with a 5kW system.
Solar panels can be generating more energy that can be used around the home at any one time. All the excess energy is then sent to the electricity grid, meaning that you’re losing out on energy being generated by your panels. By including a solar battery as part of your solar PV system, you can hold onto the unused energy to use during the night when your solar panels aren’t generating any energy.
No, Solar Panels work in all daylight conditions.
Most domestic Solar Panel installations take no more than a day with minimum disruption. Typically, the scaffolding will be erected a couple of days before the Solar installation team arrive.
Solar PV panels only produce electricity in daylight hours. You would need alternative energy sources or a battery system as well as a very large Solar PV system to be able to come off grid.
If there is a power cut your inverter will switch off, which stops any generation from your Solar Panels entering the property. This is a safety feature to protect workers who may be repairing the grid.
If you want to be paid for any the excess electricity you generate you will need to have a smart meter, most electricity suppliers are installing them free of charge for their customers if you don’t already have one.
The ROI for a solar installation is dependent on factors such as location, roof orientation and electricity usage. But typically, we would expect a payback period on a solar PV system of five to eight years.
You can install most commercial solar PV systems of 1 MWp or below under permitted development rights – without having to make a planning application.
If you are looking for a ground-mounted solar PV system, or your premises are in a National Park or Area of Outstanding Natural Beauty (AONB), then planning may be required.
For systems less than 4kW we will inform them once the installation is complete. For larger systems, permission will need to be gained in advance from the network operator DNO.
