Here's our list of top questions people ask about installing Solar.

The amount of panels you need depends on several factors including your annual electricity usage, your roof size, the orientation of the roof, the pitch (angle), and the amount of sunlight it gets.

As a rule of thumb, a typical residential solar panel is about 1.7m by 1m and produces around 400W of power. For a typical 4kW solar system, you'd need 10 panels.

A south facing roof is always going to be the most efficient place to put your panels but we can also fit panels on East and West facing roofs to pick the sun up on the morning on the East, Mid-day on both arrays and the west facing roof in the late afternoon, early evening.

We don't recommended fitting panels on North facing roofs unless the roof has a very shallow pitch.

Domestic solar panel installations are normally covered under "permitted developments" and don't require planning permission. There are exceptions to this for example if you live in a listed building, a conservation area or an area of outstanding natural beauty. 

Ground mounted systems nearly always require planning permission.

Solar PV systems have no moving parts and have a very long life span. The panels should still be generating electricity for at least 25 years. The Inverter which is responsible for converting the DC electricity the panels generate into usable AC electricity should last for over 10 years.

Many smaller domestic Solar Panel Installations should take no longer than two days to fit and commission. Scaffolding if needed will be erected a few days before.

Solar Panel systems require very little maintenance and don't require servicing. Modern systems are often connected to the internet so you can see exactly what they're doing and will notify owners and installers of any issues.
