Spectra - Spectralite solar panels


Spectralite is a range of semi-flexible solar panels made from efficient and stable crystalline cells. These cells are sealed between a fibreglass substrate that ensures durability whilst keeping weight low and a scratchproof Tedlar superstrate with excellent light transmissive properties. They are ideal for topping up 12V deep cycle batteries in leisure applications.

Price:  £54.00(Inc. VAT @ 20%)

Article Number:  CA-10/36

The cells of the Spectralite 50, 30, 20 & 10 are quite uniquely arranged in 2 halves, each producing full voltage. Should one half become shaded the other half exposed is still capable of generating its part of the panel’s power output.

These solar panels are designed to be gently curved to follow a coachroof and can be fixed using the 4 screw holes or Sikaflex adhesive to avoid drilling holes. Spectralite can be curved up to 3cm over 1m proportionately.

Spectra Solar has been designed with the yachtsman in mind so we ensure that all models:

  • Are robustly designed and built so that can even be walked on in soft soled shoes
  • Are conveniently lightweight and elegantly slimline so are easily installed
  • Include a sealed junction box with blocking diode and 3m of output cable
  • Have fixing holes sealed with an eyelet for a quality finish

How Do I Install Spectra Solar?

Electrical connection is simple, connect directly to a battery or through a solar regulator 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 of battery.

Spectra solar panels are not only an affordable choice for maintaining your batteries but you’ll even save money too on avoiding mains hook up costs and replacing deep discharged batteries. A well maintained battery delivers more charge and discharge cycles and has a longer life, so keep on saving costs.

puts out the advertised power and looks like a tough panel. Will have to see how well it lasts

Just wish that the electrical connector was at the top and not on the side like the failed one. No room to change it's positioning on my boat roof
