If you have a boat, RV, holiday home or even professional equipment that relies on battery power for lighting, computers or small appliances then you know how frustrating it can be to find discharged batteries.

Spectra solar panels are ideal for maintaining and replacing natural discharge in 12V deep cycle batteries for leisure and light professional applications. Once installed, the solar panel works quietly and efficiently at recharging without any effort on your part. We guarantee that you will find our SpectraLite solar range a reliable and affordable choice.

Thanks to their robust design the panels are tough enough to be walked on and enables them to be effective in low power commercial applications where their non-glass construction makes them shatterproof and vandal resistant.
