Solar PV Systems
4kW off-grid Ground Mount
20.25kW off-grid Roof Mount
We install ground mount and roof mount PV systems in both grid connected and off-grid electrical systems.
Solar PV is a cheap form of renewable energy and ideal for those who don't have much space but would like a renewable energy source. As a general rule of thumb it can be assumed that a 1kW solar PV array will produce around 800 kWh of energy in a year. Therefore a 4kW PV array should produce around 3,200. kWh (or Units) of energy in a year. This is only a rough guide as figures depend on site location (how far north), temperatures, shadow, array angle etc...
The cost of a system depends on many things like system size, mounting type, cable distances, scaffolding etc... That said, a 365W single solar panel costs around £200 (depending of make and model) and after the mounting frame cost, cables, isolators, inverter, installation fee etc.. you can expect to be paying around £1,500./kW of installed capacity (i.e. a 3.6kW PV system will cost in the region of £5,400).
Roof-Mount Solar PV system.
This PV array is roof mounted (flat roof) on an off-grid YHA in the North of England. This site does not have mains electricity so is powered from a battery/inverter system that is charged by a petrol generator and solar PV array (pictured here). Any energy produced by the solar PV array goes into the batteries thereby keeping the petrol generator turned off and reducing fuel costs, noise and emissions.
