Solar PV Systems
4kW off-grid Ground Mount
20.25kW off-grid Roof Mount
We install ground mount and roof mount solar PV systems in both grid connected and off-grid properties.
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 per year. This is only a rough guide as figures depend on site location (how far north), temperatures, shadow, array pitch, 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 £160 (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). These prices are changing all the time but this provides an order of magnitude!
3.1kW Flat Roof 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.
6.6kWGround-Mount Solar PV system.
This PV array is ground mounted (using a T & N type frame) on an off-grid domestic site 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 diesel generator, small wind turbine and this solar PV array (pictured here). Any energy produced by the solar PV array charges the batteries thereby keeping the diesel generator turned off and reducing fuel costs, noise and emissions. System size is 6.66kWp and consists 18 PV panels @ 370Wp.
7.3kW Integrated-Roof Solar PV system.
This PV array is roof integrated (using the GSE system) on an off-grid domestic site 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 diesel generator, 15kW wind turbine and this solar PV array (pictured here). Any energy produced by the solar PV array charges the batteries thereby keeping the diesel generator turned off and reducing fuel costs, noise and emissions. System size is 7.29kWp and consists 18 PV panels @ 405Wp. The PV array is flush with the slates for a neat integrated finish. Doing this on a slate roof can end up being cheaper than the cost of slates! We find that pure-black type PV panel is best on integrated installations.

Located in the Penrith area, this PV array is roof mounted on an insulated tin sheet roof. The PV array output directly charges a 48V battery bank (using a DC charge controller). This site does not have mains power and therefore has a diesel generator as backup. This array has added to an existing 4.5kW of solar PV. With a total of 9kW of PV the customer is hoping they wont need to run the diesel generator much after February and before September except for occasional peak loads.
