20 watt Solar
Panel
Made
of finest quality silicon photovoltaic cells, this module has excellent
dim light response property and over 15% average photovoltaic transfer
efficiency with up to 140 W/M2, power over area ratio.
Solarpaddy supplies these 20w panels for all applications.
They can easily be connected in parallel to bring the total output as
high as you may need it or connected in series for 24,36 or 48volt systems.
Our
controllers are for 12voltsystems and one
controller can handle up to 6 x 20w panels totalling 120 watts (10amps)
max. For yachts and motorhomesolar panels are very effective in ensuring
the batteries are always topped up even when not being used. This is very
important in order to extend the life of the batteries. A 20w panel will
achieve this and is enough to keep even large batteries fully charged
for the weekend user during the summer. Larger systems can be fitted which
will allow the running of fridges, watermakers, autopilots and lighting
without having to run the engine. On sailing yachts running the engine
just to charge the batteries is a very common cause of bore glazing and
of course incurs fuel costs and unnecessary damage to the environment.
