3. Even if your mppt solar charge controller panels aren't enough to run your entire house, you will still positively impact your electric bill.

Let's say you pay $100 per month on average for electricity. Have you paused to consider that this adds up to $1,200 per year? And that's not counting those very hot months when you can't help but run your air conditioning unit most of the day; for average Americans, according to MSN Money, $1,400 per year in electric bills is about normal.

In truth, the small hybrid solar inverter panels you can build using the do-it-yourself guides available on the internet are not going to be enough to make your entire home power grid independent. A typical DIY solar panel that you can build for less than $200 will generate about 60 to 120 watts; in a week, a 60 watt solar panel can generate about 1400 watt-hours of energy. What can you do with that amount of energy? Here's a look:

A laptop computer uses anywhere from 40 - 90 watts per hour of use

A 19" television uses about 95 watts per hour

A 17" LCD monitor uses 40 watts per hour

 

A radio uses 20 - 75 watts per hour
