How to choose good solar panel installers

Once you have decided to use solar power in your home, the next important thing is to choose good solar installers. The selection is made judiciously because federal and state incentives depends on the installer you choose, apart from the obvious difference it will make in the quality of the installation.

You should go for three to four bids and if there isn’t large difference in the price range, you should look at other factors to determine which installers to choose. The first thing you need to ascertain is that the installers have proper solar installation license, apart from an electrician’s license. This fact can be ascertained from the State electrical board.

Look carefully at the price being charged by the solar installers you have reached for a quote. Usually you should expect to pay about 15% of the total cost of the system at one go or $3-$4 per watt generated. This factor also depends on the kind of system you are installing. It is simpler if you are tying–up with the existing grid system of a utility company.

If you are installing an off-grid system, you need to pay for a battery bank in addition to the panels and inverter. You will also need to install charge converters, all of which will add to the complexity of the installation. You will have to pay the installers more than you would with an on grid system. You should ascertain all these things and discuss with the installers before you hire them.
