The amount of energy your home uses over a certain timeframe say a month is measured in kilowatt hours kwh.
Number of solar panels to power 4000 home.
You need at least 4 000 250 16 solar panels.
We then took 11 000 kwh and divided it by the respective ratios and then divided that number by 250 the typical panel wattage.
In order to find a range for number of solar panels we compared arizona and maine s solar panel production ratios 1 31 and 1 61 the highest and lowest in the u s.
For example if you need 4 000w hour as tabulated in the example above and have 250w solar panels.
A typical american home will need 14 36 solar panels to cover their power bill and at least 227 square feet of rooftop space to accommodate the solar panels.
The amount of power kwh your solar energy system can produce depends on the number of solar panels that can absorb solar energy and convert it into electricity.
How many watts can your solar panels produce.
The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site.
The sunpower x series panels are 345 watts each.
The amount of energy that solar panels can absorb and then produce is measured in kilowatts kw.
Picking from the section on how many sunlight hours you get from your home you can now estimate the number of panels you require.
However if you get a 370w panel you may need just 11 of them.
A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels.
In this case 4 000 watts.
