How Solar Works
Sunlight can be directly converted into electricity using silicon cells. As sunlight shines upon the solar panels, the solar panel is able convert those photons (particles of sunlight) into electrons of direct current (“DC”) electricity. The electrons flow out of the solar panel and into an inverter before being distributed into your home. The inverter converts that “DC” power (commonly used in batteries) into alternating current or “AC” power, which is the current of our grid and of your home and its appliances.

A net energy meter is able to roll backwards as you send electricity back onto the grid. Any solar energy that you do not use at the time of production will go back into the electric grid through the net meter. The utility provides you with a credit for any energy exported to the grid. At night or on cloudy days, when your system is not producing more than your building needs, you will consume electricity from the grid as normal. Your utility will bill you for the “net” consumption, and if you produce more power than you use during a given period you will receive a credit on your bill which rolls over monthly.

Solar Photovoltaic Installation
While PV systems are sophisticated electric systems, they have no moving parts and can last more than 30 years while requiring little to no maintenance. The components are designed to meet strict dependability and durability standards to withstand nature’s elements. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly. Most PV system problems occur because of a poor system installation.

Incorporating PV Systems into Your Home and Business
PV systems today can be merged easily into both traditional and nontraditional homes, powering appliances and electric systems. PV cells can be installed on your roof or by using a ground mounted system. The most common practice is to mount modules onto a south-facing roof or wall. PV systems likewise can be blended into virtually every conceivable structure for commercial buildings.

Sunlight Requirements for PV Systems
A photovoltaic (PV) system needs unobstructed access to the sun’s rays for most or all of the day to be effective. Shading on the system can significantly reduce energy output. Climate is not a major concern because PV systems are relatively unaffected by air temperatures, and snow cover typically melts quickly because panels are positioned directly into the sunlight. Abundant year-round sunshine makes solar energy systems useful and effective nearly everywhere in the United States.
