Panel sizes - 19W 10W 5W
…..An affordable range of solar panels to
save your batteries from deep discharge!
KEEP BATTERIES TOPPED UP!
Flat batteries are at best a nuisance and at worst a hazard but can be easily avoided by using the abundant and natural power of the sun. Solar energy gives you the convenience of power being available for engine starting, lighting and other low energy applications. Once installed the photovoltaic (solar) panel works quietly and efficiently at recharging without any effort on your part, choosing solar power doesn’t have to be an expensive option.
Spectra solar panels are ideal for maintaining and replacing
natural discharge in 12V deep cycle batteries in leisure
applications. In wintertime you can avoid the trouble of taking
batteries home for topping up by installing one of the Spectra
range of 5Watt, 10Watt or 20Watt solar panels. In the UK we
recommend a minimum ratio of a 10W solar panel to a 100Ah
battery to replace natural discharge in the wintertime. In the UK
summertime this increases up to a potential of 3Ah a day and
up to 21Ah weekly, typically enough to run a weekend’s cruising
electrical needs for lighting etc. Most importantly you’ll arrive to
a battery that is not flat!
SPECTRA PRODUCT RANGE AND SPECIFICATION
Choose from the range below based on the minimum’s recommended above and simply scale up on the same basis for larger
batteries, ie 20W solar panel for a 200Ah battery. For faster battery replenishment or where more power is consumed use larger
solar panels than the minimum ratio or multiple units in parallel. More than one Spectra panel can be connected in parallel to
increase the Ampere hour rating at 12V or in series to generate at 24V.

IT’S CONVENIENT, IT’S RELIABLE AND YOU REALLY CAN FIT IT AND FORGET IT!
Spectra solar panels are robustly constructed on a fibreglass substrate with
a scratch proof clear Tedlar superstrate.
They are very slimline and lightweight and have no metal outer components to
make contact with the surface to which they are fitted.
The efficient and stable polycrystalline cells are encapsulated between the
2 tough outer layers so the whole panel is weatherproof and carries a limited 2
year warranty.
The sealed junction box which also houses the blocking diode has 3m of
output cable.
The panels can be gently flexed to follow a smooth curve such as a coach
roof by up to 1cm per 30cm along the length of the panel.
Each panel has 4 grommet finished holes for fixing.
A built in diode prevents current from flowing back from the battery to the
solar panel in darkness so Spectra panels can be connected directly to the
battery.
Electrical connection is simple and the use of a solar regulator is
recommended to prevent overcharge if the system is to be left unattended for
long periods or the solar panel to battery ratio exceeds the minimum of 10W to
100Ah.
