Review on 🌞 Topsolar 20W 12V Monocrystalline Solar Panel Kit with 10A Solar Charge Controller + Extension Cable and Battery Clips O-Ring Terminal for RV, Marine, Boat, and Off-Grid System by Paul Barnes

20 watt kit is great. Includes everything you need to use the stock RV battery maintenance kit. The battery on our caravan trailer is very old and I thought it needed replacing as it is struggling to reach a full charge after being stored in the warehouse for a while. However, after being connected for a few days, this solar panel and charge controller seems to have saved our old battery from the abyss! The full charge of the battery is achieved by solar energy, while a standard charger cannot cope with this task. The solar panel appears to be quite well made and is similar in build and quality to other panels such as the Renogy. I used a rivet gun to attach the charge controller directly to the back of the solar panel's aluminum frame. This way I only have one unit and can place the panel directly on the caravan roof and have a small angle for the panel to get the maximum number of hours of direct sunlight. The charge controller is of decent quality and works exactly like most of the other controllers in this range of kits so don't worry it doesn't actually come with instructions - that's easy to understand. I would recommend this 20w kit. Excellent value for money and quality.
