Has anyone used the Power4Home Solar and Wind Power Kits? The price just sounds to good to be true.
It looks like the $200 is just for the books *smirks*
The closest I have came up with for a under $200 design involves a modified UPS and used large sat dish with concentrated solar... and that only is under $200 in parts, not time.
Let me tell you some of the "secrets" that these books sell.
1. Used non-working UPS's are everywhere and the older ones can be easly modified by drilling a hole and connecting an external 12 volt marine battery. These older UPS's don't know enough to shut down and will happy work as a power inverter.
2. Old battery's can be purchased for scrap prices... there is no such thing as "FREE" batteries. You sometimes get luckly at the scrap yard and find a good one... This is great if you don't count the hours of your time testing battery's.
3. "Cheep" solar cells can be purchased... what they don't tell you is that these cheep solar cells are rejects and in order for them to work in a system you have to spend a lot of time matching up and paralleling cells so that the whole string has the same current output. This is a very time consuming task that just involves using a small milli-amp meter. The higher the voltage the panel operates at, the harder it is.
So if time is no object...
1. Take a UPS or an inverter remove the battery and add wires coming out to a battery.
2. Get cheep solar panels and glue them to used single pain window glass. Measuring the current of each piece of cell and paralleling up sets to get a set amount of current. these sets are then connected in series to get 12 volts.
3. Manually unplug the UPS when the battery is charged to start using power from the battery.
An air conditioned outhouse would use more than 1 kwh per day - That's only 30kwh per month and at ten or twelve cents each, your electric bill would be less than $4 per month . . . . why waste $200 trying to lower that?Here's a link

The large panel shown [12'x12'?] can generate 1.3 kw for about 6 hrs each day. The average house needs 1kw every 24 hrs.

I use about 125KWH per month and I'd bet that would be much closer to 'average' than only one kwh per day

Yes, I noticed that you mistakenly said '1kw per 24 hours' instead of what your table shows . . . . roughly 1kw per hour for every hour of the day - or about 24 times your quote - The median is 8,370 kwh per year, which divided by 365 is about 23 kwh per day . . . . or nearly 24 times the amount you quoted
I have no choice but to turn in my diplomas and ask for my money back.Yes, I noticed that you mistakenly said '1kw per 24 hours' instead of what your table shows . . . . roughly 1kw per hour for every hour of the day - or about 24 times your quote - The median is 8,370 kwh per year, which divided by 365 is about 23 kwh per day . . . . or nearly 24 times the amount you quoted
So . . . . unless you live in the aforementioned outhouse, your quote is waaaaaaay off

This is awkward, but...
