Solar Panels & Stands
These solar panels using the latest in crystalline silicon technology to capture the sun's energy and convert it into electrical current - more efficient than amorphous or thin film solutions, particularly in the lower light conditions found in the UK. Accredited with the internationally recognised IEC 61215 certification. Ideal for all kinds of electric fencing.
5 Watt Solar Panel & Stand
The 5 Watt solar panel is the ideal choice to prevent battery drain with smaller energisers powered by a 12 volt battery. Provides a continuous trickle feed to maintain power levels and extend battery life. Crystalline technology provides 'all weather' charging, even in UK light conditions.The 5 watt panel will require a separate charge controller when used with batteries smaller than 35Ah.
  • Blocking diode prevents reverse current drain
  • Robust, water-resistant construction
  • Supplied with 5m cable, cable connector, fuse, ring terminals and crocodile clips
  • Credited with IEC 61215 accreditation
  • 2-year warranty
  • Instructions included
Robust powder-coated black steel. Our custom-made 5 Watt Solar Panel Stand, included, is designed to hold the panel at the correct angle to the sun at British latitudes to maximise performance. 
  • Solar panel bolts easily to steel frame
  • Slacken the thumb bolt to adjust direction towards the sun at midday
10 Watt Solar Panel & Stand
The 10 watt solar panel is the ideal choice to prevent battery drain with smaller energisers powered by a 12 volt battery. Provides a continuous trickle feed to maintain powere levels and extend battery life. Crystalline technology provides 'all weather' charging, even in UK light conditions.
The 10 watt panel will require a separate charge controller when used with batteries smaller than 70Ah.
  • Blocking diode prevents reverse current drain
  • Robust, water-resistant construction
  • Supplied with 1.5m cable, cable connector, fuse, ring terminals and crocodile clips
  • Credited with IEC 61215 accreditation
