45 Watt Solar Panel Kit Harbor Freight?
Exactly How much power will this kit produce? for example. Will it only be able to power the 2 light throughout an entire day or would it be able to power a couple TV's with a couple lights. Or a Refrigerator? washer dryer? I'm just wondering exactly what it will be able to do and if it's worth paying $200 for if it'll only power two lights. Don't get me wrong, That's great and will make a difference but i'm looking for something that will make a little bit of a bigger difference. Would the 80 watt monocrystalline solar panel be much better? if so, what would it be able to power? double?
Yes, 80 watts will be nearly twice as useful as 45 watts - but 80 is still a small number. Solar panel systems need an inverter and there's a slight energy loss at the inverter. And, if you want to use the day's energy at night, you'll need a battery or two. And every time you move energy into or out of a battery, you lose a little of the energy. All this is to say that you need to sum up the wattage of your appliances and add a fudge factor to accommodate for the losses.
I looked at the kit and was moderately impressed. $200/45=$4.44/watt; that's a reasonable price but the links I left below talk of prices as low as $2.58/watt.
Also the Harbor Freight kit doesn't contain an 'inverter' which you would have to buy. Also the wattage advertised for any solar panel assumes the thing is clean and pointed right at the sun on a clear day.
