Costs & Earnings

How much will my PV solar system cost?

The final cost of a photo voltaic installation will depend upon three primary factors…

The size of your system: The number of panels installed will, of course, affect the final price… but remember, the total generating capability of your panels will also determine the capacity, and cost, of the inverter necessary to handle the current.

The equipment brands selected: There are a range of manufacturers producing panels and inverters. Our surveyor will outline the differences in price and performance, but the final choice is yours.

The construction of your roof and ease of access: The type of roof, the need for scaffolding and the length of cable runs are all factored into the final cost of installation.
