About The SpectraLite Solar Panels


An affordable solar panel that allows you to enjoy your leisure time without worrying about your batteries

Do you have a boat, recreational vehicle or holiday home that relies on battery power for lighting, computers or small appliances? Then you know how frustrating it can be to arrive and find weak or discharged batteries, just when you need them.

Spectra solar panels are ideal for maintaining and replacing natural discharge in 12V deep cycle batteries for leisure applications. Once installed, the solar panel works quietly and efficiently at recharging without any effort on your part. And now with Marlec’s SpectraLite solar range, an affordable and reliable choice.



  • No need to take batteries away for recharging.
  • Silent, affordable and no need  for noisy and costly eco-unfriendly generators for lighting, TV and other equipment on your caravan or motor home.
  • Provides power for microwave ovens, laptops, telephones, and other electronics whilst you’re on the move.
  • Arriving to find fully charged batteries on board enabling you to switch cabin lights on immediately.
  • Knowing you’ll have fully charged batteries at your holiday home, even when you have been away for weeks.

Flat batteries are at best a nuisance and at worst a hazard. Now the problem can be easily solved by using the abundant natural power of the sun.
