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.
Monocrystalline Advantages over Cheaper Polycrystalline solar panels
purest silicone 16-20% efficiency
performs better in lower light levels i.e. in overcast skies
longest life with lowest rate of performance loss of only 0.36% per year, therefore a 100w panel would be around 91w after 25 years
better heat tolerance, i.e. performs better on hot summer days
lower grade silicone 13-16% efficiency
cheaper production costs
performance loss 0.64% per year, therefore a 100w panel would be around 84w after 25 years
slightly lower heat tolerance than mono crystalline solar panels, i.e. excessive heating of the panel causes a reduction in power generation
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
In the event that 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.
