I have 11 solar panels, 15 watts each, three still in the box.
165 watts total.
Outside of the box is worn due to storage, but never opened.
Solar controllers included.
All panels tested for output, except three still sealed in the box.
Their smaller size means they can be shoehorned into small roofs or odd spaces.
Never been installed but a little dusty due to outside storage.
Bought for a camper that never came to be.
One extra panel doesn't have a frame and has a slight crack, but it still puts out over 12 volts.
I used this one to charge my cell phones and small power tools.
Great for camper, porch, temporary setups, trailer, backup power, keeping batteries topped off, scooters, electric bikes, etc.
