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 appliances. Once installed the photovoltaic (solar) panel works quietly and efficiently at recharging without any effort on your part and now with this new Spectra range, 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 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.
