How much solar panel do i need for my house.
See how many panels you can fit on your roof using our solar panel drawing tool.
We do not recommend putting solar panels on northern facing roofs facing from azimuths 285 to 80.
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.
A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels.
The northern sky will usually not produce very cost effective energy from even the most efficient solar panels.
A 3kw solar system which consists of 12 panels can produce an average of 4 200 kwh per year.
The amount of energy that solar panels can absorb and then produce is measured in kilowatts kw.
To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average.
A professional solar installer can help calculate the number of solar panels to create the most cost effective system or you can use the solar system size calculator on this site.
The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site.
The amount of energy your home uses over a certain timeframe say a month is measured in kilowatt hours kwh.
