Spectra Lite Solar Panels

Spectra Lite Solar Panels

Quick Overview

Spectra Lite 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 super-strate with excellent light transmissive properties. The cells of the Spectralite20 & 10 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 panels power output. These solar panels are designed to be gently curved to follow a coach roof and can be fixed using the 4 screw holes or using Sikaflex adhesive to avoid drilling holes. Spectra Lite can be curved up to 3cm over 1m proportionately.

Available in power ranges from 5W to 19W

  • Range of sizes: 5 Watt or 19 Watt panels
  • 10 Watt solar panels can generate up to 3Ah per day in summertime, 21Ah weekly, enough to power a typical small remote monitoring system
  • Semi-Flexible. Panels can be gently flexed to follow the smooth curve on a coach or boat roof.
  • Rugged, durable construction. Sturdy fiberglass shell protected by a scratch-proof clear Tedlar skin
  • Slim and lightweight
  • The efficient and stable polycrystalline solar cells are encapsulated between 2 tough outer layers
  • The whole panel is weatherproof and carries a 2-year limited warranty
  • Built-in diode to control current. Prevents current from flowing out of the battery during darkness.
  • Simple and maintenance-free.
  • A solar regulator prevents overcharge if the system is left unattended for long periods or if the minimum ratio of 10W of solar panel to every 100Ah of battery is exceeded.
