Once installed on your roof solar panels convert sunlight into direct current dc electricity that flows into an inverter. Before purchasing a solar energy system for your home an important step is finding out how many solar panels you need. The inverter converts the dc electricity into alternating current ac that your home can use. With solar panels there s a pretty wide range of efficiency from around 16 up to 23.

That s almost a 50 difference so switching from cheap panels to the highest efficiency ones on the market can dramatically reduce the number of panels you need. An average homeowner needs 28 to 34 solar panels to fully offset their electricity bill with solar. Step 1 install solar panels on your roof with the help of a professional or a do it yourself solar kit. If you don t live in an area with enough sunlight then solar might not be for you.

The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site. The average cost to install solar panels is from 10 626 to 26 460 after tax credit for a 6kw to 12kw system to power an entire house. Once you install solar panels at your home you can reduce the electrician s charges by connecting them to your house s electricity yourself. Solar only works if there s sunlight.

The main takeaway is that the more efficient the panels are the more power they can produce and the fewer photovoltaic panels you will need on your roof to get the same energy output as you would get with polycrystalline or thin film solar panels. Any additional power generated that you don t use gets pushed back into the electric grid for a credit on your electric bill. A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels.

Most solar panels last for 50 years have a 25 year warranty and start generating a return on investment after 8 years. The average solar panel payback period is 7 to 12 years and solar energy saves 600 to 2 000 per year on electricity costs. You should try to supply about 5000 watts of power per day to the house. Use the highest efficiency solar panels you can.
