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. A 20 watt panel used in conjunction with our 55 Ah battery will provide stand-by lighting for garages, sheds, greenhouses and farm outbuildings. Most importantly you’ll arrive to a battery that is not flat!
It's easy to extand a basic system by adding in another panel or a windcharger at any time.
Look at the key features of Spectra panels.
| 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. |
