PHOTOVOLTAIC CELLS (or PV cells) convert the sun’s energy into direct current electricity. PV cells are the basic building blocks which make up solar panels. An arrangement of panels makes up a solar array. Depending on the physical size of the array determines the amount of the sun’s energy which is captured and used. A good starting point in determining the size of you solar array is to look at your power bill and see how much energy you use. Once that is determined, the two factors which typically determine the array size is available space and cost.
SIZE & SPACE
You may determine that you want an array to meet all of your energy requirements and find out that you haven’t enough space to put the required array. Folks typically put their arrays on their roof. The reasons for this are that it cost less to put arrays on roofs. Also, most people don’t have large yards to ground mount an array. Another consideration for determining the size of your array is cost. In recent years the costs of PV systems have come down.
In order to determine your systems cost, the next thing to take into account is your home or business’ orientation to the sun. Armed with the street address and power bill, we use our programs to produce a comprehensive and concise analysis for your location. In three or four short pages, you will have a majority of your questions answered. All of our systems are engineered for your location. The engineering is for both electrical and structural considerations. Working with your local building department, your system will meet and pass stringent inspection guidelines. First, let’s answer these two basic questions for you: How big of a system will you get and how much will it cost.
