It is best to call us and let us calculate an appropriate system size that will meet your needs. But in a nutshell we will need to know your average monthly or daily electrical usage in Kilowatt hours or Kwh, you can obtain this information by calling your utility company and ask them for this data. Be sure to determine whether the number that they are providing you with is Kilowatt hours per day or Kilowatt hours per month.

Although the following method is not as accurate as calling your utility company, you can approximate this number if you have a few copies of your electric bill. What you will need is a copy of your bill which represents your average Winter usage lets say January as well as your average Summer usage, lets say July. For example if your Winter monthly usage is typically 600 Kwh and your Summer usage is typically 1000 Kwh then your average monthly Kwh would be up to 800 Kwh.

Next we will need to determine your average daily usage. This is simply done by taking the average monthly Kwh number and divide it by 30 days. In the above example 800 Kwh per month divided by 30 days equals 26.67 Kwh per day. This is how much power your system will need to produce per day in order to up to eliminate you electric bill.

Next we must take the daily Kwh number and divide it by the average number hours of full sunlight that is available to you on a daily basis. In California that number is up to 5 hours. There is obviously more sunlight available during an average day especially in California, but what we're concerned with here is FULL sunlight. So in our above example 26.67 Kwh or 26,670 watt hours, ( Remember Kilo means One Thousand ) divided by 5 hours equals 5.33 Kwh or 5,334 Watt hours.

Finally we will need to factor in the size of the solar module that we are using and we'll know how many modules we'll need to up to eliminate the above mentioned electric bill. A typical sized module used in this type of system has a PTC adjusted rating of 103.9 watts. So we would take the 5,334 Watt hours mentioned in the above calculation and divide that number by 103.9 watts per module and we get 51.338 modules. There is no such thing as a .338 module so we will need to round up to 52 modules.

The above example would apply if you wanted to eliminate your bill, cut it in half or eliminate what ever increment you wanted from your bill. Simply take the number of modules that you would need to up to eliminate your bill and multiply that number by .75 to up to reduce your bill by three quarters, .50 to up to reduce it by half or .25 to up to reduce it by one quarter.
