Product Information

The Professional Grade CS-135-24, 24V solar panel is a 24V version of the incredibly popular 135W CS-135, with all the benefits of our ultra high-efficiency monocrystalline solar panels, but allowing you to operate at 24 volts without the need to connect panels together in series, or use an expensive MPPT controller.

At 135 watts, the CS-135 24V solar panel is ideally suited to medium power installations, such as a touring caravan, motorhome or boat. Typically 135W is sufficient to run a TV/radio for a few hours a day, low-energy lighting, a small water pump and general day-to-day charging of mobile phones and laptops, etc.

The Professional CS-135 features the latest solar cell design from the US and high quality finish, which allows you to use this solar panel in all weather conditions. Unlike cheaper models available on the market, the CS135 produces a far higher voltage per cell, is less affected by low light and, in high summer temperatures, maintains a high power conversion efficiency.

Due to popular request, we now offer our professional solar panels with or without our 5 metre 'clever-clip' cable set.

This solar panel is 'Power guaranteed' for 25 years.

Key Professional Grade Features:

  • Sturdy anodised aluminum frame with mounting holes to match the industry norm enables easy installation on currently available mounting structures.
  • Unique back-contact solar cells with conversion efficiency up to 21.5%
  • Low voltage-temperature coefficient ensures maximum battery charging current is available even during high-temperature operation.
  • Exceptional low-light performance and high sensitivity to light across the entire solar spectrum maximises yearly charging performance in any weather.
  • Highest quality 4mm-thick high-transmission tempered glass provides enhanced stiffness and impact resistance.
  • Aerospace style cell interconnects with in-plane strain relief provide extremely high reliability.
  • Advanced EVA encapsulation system with multi-layer backsheet provides excellent long-term package durability.
  • 25 years warranty on power production.
