GRANT PV 144KW ON ROOF PORTRAIT PACK Grant Solar PV utilises free energy from the sun to generate electricity. It relies on daylight to generate power through the use of photovoltaic cells within roof-mounted modules.
The modules are simple to install, as they fix to a roof in the same way as Grant Solar Thermal panels in an on-roof, inroof and flat roof arrangement, both landscape and portrait.
The electricity produced by Grant Solar PV can be used to drive any appliance that is powered by electricity. An inverter (usually situated in the loft) converts the DC current into usable AC current that can be used as power.
A 1.80kW Grant Solar PV System (10 x 180W modules) should produce around 1,693kWh of electricity per annum (this figure may vary, depending on location). To put this into perspective, the average household usage is 9-10kWh per day.
