Solar Panel Harbor Freight
Solar Panel System at Harbor Freight?
Harbor Freight sells a 75 watt solar panel, a surge power inverter, and deep charge batteries. But no one there can tell me how to put it all together. I want the end output to be a simple power bar that I can plug my devices into. I live in an apartment so I can not wire it directly into the grid.
Please only serious responses. Don’t waste your time and mine.
i wouldn’t.
- harbor freight isn’t known for the best quality stuff.
- 75 watts assumes roof mounting, at 90 degrees to the sun, on a bright day. you’re going to get considerably less. and only when the sun is highest in the sky.
maybe you should look at, your computer, for example.
if you’re using it for 4 hours, and it has a 500 watt power supply, and you add 200-500 watts for the monitor, and some for the printer, modem, etc, you’d use 5kw that day.
your 75 watt panel, generating maybe 50 watts at most, for maybe 4 hours when the sun was highest, and shining directly on the panel, would generate 200 watt hours. it would take 25 days to generate the electricity you’d use in 1 single day.
in the winter, you’d be pretty much out of luck. there just isn’t enough bright sun.
clearly, it’s up to you, but there’s a harbor freight near me, and i’ll not be rushing out to get such a system.
further, most appliances are quite voltage sensitive. you really do need to have the voltage in the 110-120 range. too much out, either higher or lower, will shorten the life of appliances at best.
