Excellent solar panels

These panels are fantastic I now have 7 of these 3 of them mounted flat on top of a narrow boat Still producing power right until the sun drops out of sight Low angle sunlight not a problem either still kicking out near the max output as soon as the sun is in the sky Very impressive panels Well worth the price
