Understanding How Solar Energy Works

The sun has the power to generate enough electricity to keep your home sufficiently powered with the help of some essential technology. If you’re considering embracing solar power as your primary source of electricity, understanding how it works can help you determine how much of a smart investment it may be for you.

Solar Panels

The sun’s energy is converted into usable electricity through the use of solar panels. Panels can be placed on the ground if your roof isn’t able to safely support the weight. The most common type of residential panels consist of photovoltaic (PV) cells.

Inverter

This device is needed to convert the direct current (DC) the PV cells collect into alternating current (AC) that can be used in your home. Make sure you have a quality inverter so you’ll be getting the maximum possible power from your panels, which translates into increased energy efficiency.

Electrical Panel

Often referred to as a “breaker box,” this device is needed to transform the AC electricity from the inverter. This is how the power is delivered through the circuits and wires in your home.

Utility Meter

A meter will be necessary to keep track of your energy usage. It will move backwards when your solar system generates more power than what’s being used. This excess power is used to offset times when it’s cloudy or dark.

Connecting to the Grid

Having a solar panel doesn’t mean being totally free of the grid. You’ll still need to tap into your local power grid to compensate for times when you need more power, often at night. Storage of solar energy from during the day can offset costs. The average annual savings with solar energy for homeowners is about $600. Some states offer tax credits and you may be eligible for a federal tax credit as well. You’ll also want to consider whether or not you lease or buy residential solar panel systems and factor in how long it will likely take to recoup your investment.
