The 28 Watt Solar Panel is ideal for charging consumer appliances such
as
mobile phones, electric
toothbrushes, digital cameras, and more power hungry devices such as
laptop computers*. The 28 watt
panel provides a
continuous trickle feed, maintaining and extending the life of any 12
volt battery and is particularly suited for maintaining 12V
caravan
batteries (for example up to a week long holiday). It is also suited to
larger projects such as powering electric gates or
garden pumps / fountains*.
A 28 Watt solar panel for that week long caravan holiday
This
solar panel uses a high efficiency crystalline cell for “all weather”
charging. It is water resistant, has a robust construction for outdoor
use and a 20 year cell warranty and 10 year module
warranty. The 28 Watt solar panel is supplied with all the
necessary cable (5m),
connectors, detailed installation instructions and a
free digital test
meter to enable you to analyse the performance of both
solar panel
and battery.
What else do you need?
The 4Ah (STS01204)
Charge
controller
or equivalent
must be
used with this kit to protect the battery from being
overcharged and to prevent reverse current drain. If you do not have
one, it can be bought
here.
A solar panel
carry
bag
is available. This is a great addition where your panel will be
used in temporary locations - e.g. when used with a touring caravan.
Made from hard wearing shower resistant Cordura, the carry bag offers
tough custom built protection for your solar panel.
A
universal
stand is
also available. It quickly and easily fits to the panels enabling them
to be used
“free standing”, angled to suit the time of day/year and conditions.
