I have it outside hooked up directly to a solar water pump that requires 14 watts. It works only in direct sunlight since there is no battery in the loop, but that is what I expected. It is holding up well in the weather. Product Info. ACOPOWER 15W Polycrystalline Solar Panel is the key component to a system when going solar Off -Grid system . These panels are relatively compact and are a breeze to set up. Whether you are going camping in the mountains or taking a trip to the beach, this panel can be a great start to your off-grid system! This panel has several uses including marine, dry camp, RVS and other off-grid applications.

Best I could get from this thing in direct view of the Texas sun in June was about 18V OC voltage and around 350mA SC current. Far below what I expected based off of the specs for it. I purchased a 30W solar panel made by Coleman thats about the same width, but twice the length and was able to get similar voltage, but almost 15A SC current. Save your money and get something else.
