I spoke with someone from the company who said that the controller between the solar panel and the battery is defective. Very soon they will have a new solar panel and a new controller. I am willing to give them a try again next year and if it works I will change my review but for now, I would hold out for the next version.In the meantime, I would go to the laundromat daily, do a load and charge my battery at the same time. It did cut into my time, but it meant I could keep camping and enjoying our trip as much as possible. The last two days I was able to not go in to the laundromat as two hours charged it about 50%.I am sending back the solar panel for a refund, and we'll see next year how it goes. For their customer service I am raising the Stars a bit. Before you buy, I would check with their customer service to see if the quality of the materials has improved....I am so very upset. Currently, I am camping, and before we left, I tried it out in my back yard to check it out.At that time, it worked, but I only had it plugged in for about 2 hours.Two days later, we left to go camping.This morning, (in the middle of our trip), I went to plug it in. I kept the battery in the shade, under the table, and kept as much of the cables in the shade.We puttered around the camp site for about an hour, and when I went to check on it, the BSP SP40 Controller (model: SP40-CTR was fried. It was super hot to the touch, and when I disconnected it, it started to rattle.I immediately disconnected my battery, (I'm glad I only connected one), but, it fried it. The batteries and connector were over $500.00.Depending on how the company responds to my request for not only a refund, but a new battery, will depend on if I change my stars and review.I still suggest not, not, not getting this.Not only did it fry my battery, but we now have to cut our vacation short, and I now will be out the campsite fee for the days we can't stay.As I said, I'm pretty upset. I guess you could say that I am pretty fried as well. ### ⭐⭐⭐⭐⭐ Awesome product! *by A***R on Reviewed in the United States on September 18, 2018* I took this solar power panel system to the Canadian Boundary Waters and camped for a week. I needed it to supply power to my CPAP rechargeable battery (that powered the cpap machine). It charged the portable battery to about 60-75% each day. It was sitting out on a rock in the partial sun for 8-10 hours daily. It charged on cloudy days, as well, but not as thoroughly. It IS weather/waterproof (the panels, not the connections to battery!). I was VERY pleased with this item. ### ⭐⭐⭐⭐⭐ Charges on a cloudy day. *by A***R on Reviewed in the United States on June 1, 2019* This solar panel kept my freedom battery charged for 7 nights in the Quetico wilderness. Even on all cloudy days it charged the freedom battery to 100%. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/16552458-battery-power-solutions-freedom-40w-solar-panel](https://www.desertcart.co.uk/products/16552458-battery-power-solutions-freedom-40w-solar-panel) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-05-01*
