It depends on your roof size, pitch, orientation and any shading. A free site survey is the only reliable way to confirm this, we won't recommend a system without seeing the property first.
No, but it increases the value of your system. Without a battery, unused electricity is exported to the grid. With one, you can store it and use it later, reducing how much you rely on grid electricity at peak times.
Yes. Solar PV panels generate electricity from daylight, not heat. Even on cloudy days, they can produce a significant amount of power, and output remains strong throughout the year.
We install across Cardiff, Swansea, Newport and the wider South Wales area. If you're just outside these areas, get in touch and we'll tell you honestly whether we can look after you properly.
A typical starting package, including 10 x 500W solar panels (5kW system) and a 5kWh battery, is fully installed from £9,999. Your exact price depends on system size, roof type and any additional equipment.
