Can two solar panels power a whole house? My house has two bedrooms, two bathrooms, air conditioning, electric kitchen appliances, a 24" TV, and a computer.

I'm sorry to tell you that the answer is no. I've lived off the grid for 15 years and solar panels have come a long way. Even with the most expensive solar panels on the market, you would need about 15 solar panels and a dozen or so deep cycle batteries. If you live in the desert or any environment where you really need to run your air conditioning a lot, then you will need even more. Your air conditioner is the most power hungry "appliance" in your home.

You may want to use solar panels to power your whole house excluding the air conditioner. For your air conditioner, switch it over to gas.

Also, if you work during the day, leave your air conditioner off. In this case, your solar panel system that is powering your whole house is generating power and making your meter run backwards as you are selling the energy during the day back to the power company. Then when you get home at night, you buy energy from them when you turn your AC on.

You should be able to cut your bill by 75% or more doing this as long as you don't live in too hot a climate and thus don't have to run your AC that much at night.

   Use the calculator on this blog (link up in left corner). You put in the appliances and it will tell you how many solar panels you will need to power your whole house.

   You’ll need a full array of rooftop panels to power a whole house with its devices. Just 2 panels won’t be enough from a wattage standpoint.
