This panel, like the rest of our SolarGo2 rigid panels, is built to last with a strong full frame aluminium structure, the latest generation A-grade mono crystalline solar cells, a tough low iron, high light transmission glass front and 5 metres of high-end 2.5mm² UV stable DC cable making sure you get the best transmission of power from your panel to your controller.

Designed to last in an outside environment for years to come whether it’s on top of stables, a caravan, a motorhome or even a boat out at sea. We also give you a 20- year cell warranty* and a 10-year product warranty** as standard on our rigid solar panel range giving you real peace of mind with your SolarGo2 solar panel.

The 40W panel is ideal for small off grid projects from providing power for a stable lighting project, keeping a battery topped up in a caravan or boat to running lights on building signage and keeping telemetrics systems working along the roadside.

The SolarGo2 40W panel is designed to be outside and work in all weather conditions, providing you with variableamounts of power throughout the year depending on the weather conditions and the time of year.

As an example, we would say it will give you an average of around 12Ah (240Wh) per day in the summer in the UK and 1.6Ah (32Wh) per day in the winter. This panel will require a charge controller if being connected to a 12v battery.

*The 20-year cell warranty is based on the cells producing over 80% of the original power in year 20.

**The 10-year product warranty is forany manufacturing defects. Any accidental damage etc is not covered.

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 Flexi panels are designed to last. We give you a 1-year product guarantee and a 20-year cell guarantee.
