frequently asked questions
How do I maintain my PV panels?Solar PV needs little maintenance - you’ll just need to make sure trees don’t begin to overshadow them. Many installers offer basic maintenance packages, however in most cases maintenance is not required.
What size system do I need? That depends entirely upon the roof size available. A typical house can accommodate anything between a 3 kw and 4 kw system. A 4 kw system can be achieved using either 12 or 16 panels, dependent on the number of watts per panel. A typical panel is 250 watts, however some manufacturers offer 333 watts, meaning you can still achieve a 4kw system even if your roof only has capacity for 12 panels.
Do I require planning permission for Solar PV on my roof?Planning permission is not usually required, but may be on listed buildings or buildings within conservation areas.
Where is the inverter situated?Inverters are usually situated in the loft, to be near to the solar panels. Or if loft space is not high enough, then will often be installed in a garage.
What is the difference between Mono-Crystalline and Poly-Crystalline panels?Mono-Crystalline are produced from solid mined silicon, wafer sliced and etched to create a greater surface area. A more durable product and having a similar analogy to a Duracell battery: high output for a long period. 90% of the UK has Mono-Crystalline panels. Poly-Crystalline are produced from man made silicon and are usually lower in conversion to the Mono-Crystalline however differences are deemed as being nominal.
