I bought the 30 watt solar seystm from harbor freight, it cost $129 on sale, I have it hooked up in my shed to a 115 amp hour battery. My panels have about 6 hours of direct sunlight, which adds up to 240 watts of charging into the battery. This means that I can put another 115 amp hour battery into the seystm. I want to use it to run the lights in the shed as well as an emergency supply of electricity to run cell phone chargers and a small digital tv seystm to watch the news and weather.

Above comment does not pertain to Sunpower.

Watts and amp-hours are not the same thing.

HFT's 30W solar panel system probably does not produce 30W.
