Why Go Solar
Beat energy inflation, energy security, remote location power sources (save a fortune on armoured cabling), mobile power sources, fast payback periods over conventional fuel sources such as diesel generation and hook-ups, keep batteries fully charged at all time as deep discharge shortens life, environmentally friendly power which reduces carbon emissions to slow global warming and climate change.
Sheds, Stables, Boats, Caravans, Motorhomes, electric fencing, road/ path/ driveway illuminated signage, campsites, yurts, multi-panel off grid power source for small buildings, remote telecoms, mobile food outlets, and many more…
Independent Off-Grid Solar Power Source
One or more solar panels can be connected a battery bank and power inverter using a solar charge controller. You can therefore have a 240v power supply anywhere in the world without grid supply. Please see our solar power kits.
Solar Panels do still generate power during cloudy and rainy weather
A rough to guide solar panel power output relative to weather conditions:-
100% power output – clear sky midday sun with the panel fully tilted toward the sun’s position in the sky.
75-85% output – clear sky midday sun but with the panel laid flat
50% output – thin cloud, or intermittent small clouds
10-20% output – midday overcast sky or rainy conditions
If the solar panel is in shade for a prolonged period, our solar panels either have one or two built-in bypass diodes which will enable the panel to continue generating.
