Review: Very good purchase - Bought this to set up some lighting in my shed. Fairly straightforward to fit it all together although the instructions are tiny and I had to look up most of the terms. Had to replace the batteries on the wife’s mobility scooter so the old ones will be useful just for lights. So far so good, it all seems to be working OK after a couple of weeks, battery staying charged enough for lights. Made a wooden frame to attach the quite sturdy panel to the side of the shed (not much direct sunlight this time of year but will be in a few weeks time) and put the controller inside. The lead was a bit short so extended it using some 13 amp twin and earth electrical cable which seems to work alright. Overall a good buy for the price and useful as my first foray into a solar power project and my led light strips work fine, who knows I may be expanding it soon!
Review: Easy to set up totally suitable for my purpose. - I bought this solar panel to trickle charge a car battery in the shed. I use the battery for a 12v lighting system and a small inverter as I have no mains power in there. Its May at the moment and we do have a reasonable amount of sun but I have to say the panel is doing an excellent job of keeping the battery topped up. The panel doesn't have much in the way of mounting brackets, there are simply four holes in the inner surround of metal. It was a bit fiddly but with use of some suitable nuts and bolts I fed the bolts through the holes in the surround, through the wall of the wooded shed and put washers and nuts on the inside. I then put a bead of sealant around the panel to stop the rain dripping down the back. Although fairly generous the leads from the panel to the power controller were not long enough for me so I ended up extending them which is straightforward enough just ensure you get the polarity right. Its worth using good quality wire as thick as that supplied (at least) so you don't get too much of a voltage drop. The power controller isn't the best or the most complex but I found the default settings work fine for my purpose, just follow the instructions to connect everything in the correct order. You can alter the charge voltage and cutout voltage if you wish. The screw fittings for wires on the controller are a little unconvincing but seem OK in practice. At the price point I'm pleased with this panel and I now have exactly the setup I wanted in my shed.

## Questions & Answers

**Q: how harm full is for a person**
A: Very harmful if you ate it. I wouldn’t use it as a parachute either.

**Q: The Solar charge control keeps fading out, I am just trying to use the solar panel to charge usb devices. So far no luck, is mine broken?**
A: Do you have a 12v battery attached?  You need a battery attached, the panel is not designed to run anything directly, it is designed to trickle charge a car battery.  The power from the car battery is what will charge your USB devices.

**Q: can i leave this system connected to the car permanently ie even whilst driving ? TIA Pam**
A: I wouldn't have thought so, you would need to isolate the controller, as your car alternator will be charging your battery as you are driving. there are controllers on the market that are able to be connected to a running charging system, they are a lot more expensive than this system.

**Q: Is the solar panel waterproof, can i mount it outside?**
A: The solar panel is fine, but I do get issues occasionally with the controller when wet.

### ⭐⭐⭐⭐⭐ Great piece of kit - does exactly what we need it to do
*by L***N on 19 July 2025*

Great bit of kit. Bought to trickle feed/trickle charge the leisure battery (which powers the sink tap and the internal lights) in our horse truck. It is lightweight, but sturdy. We store it behind the drivers seat, and then, when parked, position it on the dashboard. The panel can be permanently fixed, but for us that wouldn't work and we like the flexibility of being able to put it into different positions in the cab to catch as much sun as possible (we added a long wire so that we are able to do this). It does an excellent job of keeping our battery topped up, meaning we dont have to take the battery home to charge it . The control unit is great cos allows you to monitor the charge level in your battery, and has 2 USB ports, so is great for charging your phone
