Evergreen A Series Panels offers a range of high quality String Ribbonâ„¢ solar panels offering exceptional performance, cost effective installation and industry-leading environmental credentials made with our revolutionary wafer technology. These evergreen modules offer 0% to 5% output. Evergreen is the first manufacturer to offer a positive 5% output.

Photovoltaic (PV) systems use solar electric panels to directly convert the sun's energy into electricity. This conversion of sunlight to electricity occurs without moving parts, is silent and pollution free in its operation. The solar electricity fed through electronic equipment is converted to utility grade electricity for use directly in the home.The solar electricity can be used to offset the need for purchased utility electricity or, if the PV electricity exceeds the home's requirements, the excess electricity can be sent back to the utility, typically for credit.

Home with PV panels Different types of photovoltaic products are available today from numerous manufacturers. The supply of PV collectors worldwide has increased from 20 to 30 percent annually to keep up with the demand for this renewable energy technology. PV modules (or solar electric collectors) are different from solar thermal collectors (that convert the sun's energy into thermal (typically hot water) energy. Photovoltaic modules are usually rigid, rectangular devices ranging in size from 2’ by 4’ to as large as 4’ by 8’. Some PV module technologies are flexible and as large as 2’ by about 20’ or even larger. Rigid PV modules typically have a glass cover while the flexible modules have a very durable film cover. Both types of PV module construction have been rigorously tested to survive storm and hail damage and are resistant to degradation from ultra-violet rays.

Most residential PV systems are used in conjunction with utility-supplied power. Excess power produced during daylight hours can be fed back into the utility's lines, while utility electricity is used in the home when the house demand is greater than can be supplied by the PV roofing. Typical residential PV systems commonly have a peak power production of between 1,200 and 5,000 watts, AC - requiring from between 150 to over 1,000 square feet of installed area depending on the efficiency of the PV technology used.

Most often, PV panels are installed on roofs, but they can also be installed as free-standing units, on a pole on the ground, or even on complex tracking structures that change with the sun's angle during the day.
