Review on 🌞 Efficient 20W 12V HQST Solar Panel to Charge Batteries for RV, Boat, Marine, Cabin, Tent and More! by John Maynard

Installed on the roof of my backhoe because my generator stopped working. Since I rarely use an excavator, the battery should stay charged and ready for my next job. For the first week or so I thought it would work, but for the past few weeks the battery has been below 50% even after 6-10 days in the sun. I disconnect the battery cables when it's been idle for more than a few days and leave this solar charger connected to the battery, but the battery isn't charging. Not very impressed but Revain's past return window!
