Pairing our lightweight solar panel (including integrated fixing brackets) with a premium MPPT controller and you get a complete, high‑efficiency solar solution in one smart kit. Every bundle includes the panel, MPPT controller, gland, fuse, and bonding glue basically everything needed for a clean, reliable installation.
The panel’s built‑in mounting brackets make fitting fast, secure, and hassle‑free, keeping weight and height to a minimum while maintaining excellent aerodynamics.
Perfect for motorhomes, campervans, boats, and off‑grid setups where every kilogram and every millimetre counts. And with a 10‑year warranty, you can enjoy long‑term confidence and total peace of mind
The SolarGo2 Lightweight 250W solar panel kit is designed to be outside and work in all weather conditions, providing you with variable amounts of power throughout the year depending on the weather conditions and the time of year.
Unsure if this is the correct panel for you? Call us on 01684 607002 for some friendly help and advice.
How can I tell if my panel is working?
You will need to have access to a DVM (digital voltmeter) that can measure DC voltages up to 100V or higher and DC Amps up to 10A. Then with the wires from the panel (not connected to anything else) connect the red probe to the red wire and the black probe to the black wire to test the voltage coming from the solar panel.
This should give a reading of between 14 and 26 Volts DC depending on light conditions at the time. Then set your DVM to test the current, i.e. amps, coming from the panel and connect the probes as before. This may involve moving one of the probes on the DVM.
The results will vary depending on the panel, but any positive reading indicates that your panel is working. Both tests are basically short circuiting the panel. Check your solar panel instructions for more help on this.
Do I need to connect the supplied cable to my solar panel?
All Our SolarGo2 panels come with a pre-installed cable. This cable is 5m long and is designed to get the very best power transfer from your panel to the controller. This is normally plenty of cable for your install, but more is available on our web site.
What is the difference between mono and poly-crystalline?
The main difference between the two technologies is the type of silicon used in the solar panels:
Mono-crystalline solar panels have solar cells made from a single crystal of silicon, this is still considered the best of the current solar panels.
Poly-crystalline solar panels have solar cells made from many silicon fragments melted together. And although this has improved over the years with technology it is still not as good as mono-crystalline. It is more of a ‘best of the rest’ panel.
My solar panel has been damaged, and the glass is cracked. The solar panel is still creating power so can I leave it?
Your solar panel will need replacing ASAP. The cracked glass will let water onto the silicon and as soon as we have a frost the water will freeze and break up the silicon inside the panel stopping the panel from working. This can also create a short circuit that could make the installed solar controller fail, costing you more to fix the problem.
Are my panels weatherproof?
Yes, all SolarGo2 panels are designed to be left outside all year-round rain or shine. However, they are not designed to work underwater i.e., submerged.
How long should my panel last?
Our SolarGo2 rigid panels are designed to last. We give you a 10-year product guarantee and a 20-year cell guarantee.
