How many panels of solar cells i need to produce enough electricity for running a house's devises and machines
Answer:
There are a number of factors that are necessary to consider in order to answer your question. First of all, you have to know the total load of the electrical appliances in the household. In order to make sure the solar system can supply it, you need to see if the solar cells are capable of supporting the maximum load that will be drawn at one time, and also the regular load throughout the day. To get a ballpark figure of load, check your latest utility bill. Usually, they will give you your total kilowatt hours used per month. Divide by 30, and you'll know the average kilowatt hours used per day by your household. Keep in mind that a newly installed household solar system usually supplies 3-5 kilowatts per day on a sunny day. Is your average daily usage within that range? If not, you would need a larger household solar system, with more panels and capacity.
Since different models and brands of panels have different capacity, and different households have different usage patterns, it's impossible to say offhand how many panels are needed for an unspecified household. But if you start with the energy needed, and compare that to solar systems being offered in your area, you should be able to find the information you are looking for.
It depends where you live, how much sunlight you get, and how much electricity you use.
The average size of a solar system that completely powers a house is 2,000 watts. That's not a lot of power--just enough to run 20 or 30 light bulbs. To make 2,000 watts of power you need solar panels that total about 24 feet long by 10 feet high.
To calculate, you must know many things. Primarily all the electrical loads and how many hours a day they are used.
My friend has a 100% Solar home. He has 12 panels, Battery Bank, and 10 KW generator. The system cost him about $30,000. His house is about 1600 square feet. He still does not have enough to have air conditioning or heat, but the system does a pretty good job of handeling his other loads, except when it is rainy weather, as long as they are careful with power use.
You need to do a load caluculation with the solar company first. We guessed wrong and still had a bill for a couple years. Then we found a great product! I'd get an XPower first:
They advertise cutting your electric bill up to 25%; but we noticed closer to 50% reduction. There's a 6 month money back guarantee & it's also good for the environment (it also recycles wasted electricity)
I'd get one of these and then have the solar company do the quantitative anaylsis on your electric usage.
