General Solar PV Questions

Got a question about solar PV in general? With over 20 years experience, we're sure to have the answer.

Q. What is the best system size to fit?
A.

It really depends on the roof area available and the household's power need. Most domestic PV systems are between 2-4kWp. 4kWp is the largest possible without requiring consent from your electricity distributor.

Q. What maintenance does a solar PV system require?
A.

Provided the panels are at an angle greater than 15 degrees, they are self cleaning and require no additional maintenance other than a standard annual electrical check.

Q. What’s your manufacturing lead time?
A.

Our lead times can vary greatly depending on our current order book. For a domestic system, it’s usually between 4 and 8 weeks. We can give you an estimated lead time on request though this will be subject to change until we receive your order.

Q. Does my roof need to face South?
A.

No, although a South facing roof will generate the most energy, East and West facing roofs can also be suitable for solar. In fact as they often generate more in the morning and evening, they can work out more cost effective if your home is empty during the day.

Q. Do I need permission from the electricity distributor?
A.

For a system under 4kWp you do not need permission to install, but if connecting to the grid, they should be informed of the installation and commissioning
