Solar power is derived from the energy of the sun harnessed through a photovoltaic (PV) system. PV units were initially used as a source of electricity in small and medium sized applications. One of the first commercial uses of a PV system was the sun-powered calculator. Today, PV units are used in homes, businesses, and the number of grid-connected systems has grown into the millions. Utility-scale solar energy stations have been built and produce hundreds of megawatts. Let’s take a look at the different parts associated with a PV home module and discuss why you would want this type of unit.

Solar Panel

A panel, or cell, is designed to absorb the sun’s energy and transform it into electricity or heat. A PV module is a packaged and linked assembly of cells, which make up the array of a photovoltaic system that generates and supplies electricity in commercial and residential applications.


Photovoltaic systems convert light into a DC electrical current. An Inverter is a device that takes the low-voltage, high-current DC signals from the cells and converts them into 120 volts AC, which is directly compatible with your local power grid.

Why Solar Energy

Over the years, using the sun for energy has developed into an assembly that is truly cost effective, and there are many reasons to use this energy. It’s free-the sun’s energy allows you to use sunlight and transform it into energy for your home. It’s clean and can be used to heat or cool your home without any impact on the climate. These systems do not produce carbon dioxide emissions. It’s renewable while other energy sources, such as oil and gas, have a finite amount of product available. Whenever there’s sunlight, you can produce electricity. By having your PV module plugged into your power meter, any unused energy you produce will go to the local grid, reducing you utility costs. Local, state, and federal government agencies usually provide monetary incentives, such as rebates, while others will loan you money toward the purchase of a PV system at a lower interest rate. Lastly, you will increase your home’s value.

Battery Backup Systems

Installing a battery backup unit to your PV assembly increases your chances of not having to use your local energy company. Many appliances can be powered off these units. Several of these units can be charged by the sun, grid, or gas generators. If your local grid goes out, your battery backup unit will supply electricity while charging off your PV power cells.

Solar power is a viable source of energy, considering in some areas the cost of energy has increased over the past few years. The general public is usually unaware of the details of these types of energy-producing units.
