Solar panels have the ultimate green credentials, and gone are the days when you needed to pay tens of thousands of dollars to catch the sun. With government rebates and increasing demand, solar panels have moved into the realm of possibility for the average homeowner.

Once installed, panels can generate pollution-free electricity from the sun for 25 years or more. Even manufacturing them takes relatively little energy. According to Martin Green, executive research director of the Photovoltaics Centre of Excellence at the University of NSW in Sydney, “the energy payback is less than three years, even less for thin film”…

“Learn the basics of solar panels, inverters, installers, siting, financing and more. Harvest your own clean energy from the Sun.

The following guide will help you start exploring the possibility of going solar at your house. Let’s first get up to speed on solar electricity basics with a few key definitions:

PV Module: aka a solar panel, converts energy from the sun into direct current (DC) energy. PV Modules come in varying wattages and sizes. Typical PV modules used on home installations are 200 watts and about 14 square feet.

PV Array: A number of PV modules wired together. Using 5 x 200 watt PV modules creates a 1,000 watt PV array. Typical array sizes range from 2,000 to 5,000 watts and up.

Inverter: Converts DC electricity into alternating current (AC) electricity used around the house. A 3,000 watt inverter will output 3,000 watts of AC electricity given enough PV input. Typical inverter sizes range from 2,000 watts to 7,000 watts…”
