Frequently Asked Questions about Solar Energy Systems

Will a solar energy system produce enough energy to handle all my electricity needs?

For the average customer, a solar system will produce 20-50% of their annual energy needs, depending on the size of the system and the energy requirements of your home. The size of the system that is right for you depends on how big of an investment you want to make and how much unshaded area is available.

If a solar energy system only produces 20-50% of my energy needs where do I get the other percent from?

To meet the rest of your home’s electricity needs, you will need to rely on power from Jackson EMC’s distribution system.

How much electricity will my solar system produce?

The amount of electricity generated by a solar system depends on several factors: system size, orientation of the system and shading. Typically, a solar system using 120 square feet of solar panels will generate 1,000-1,440 kWh per year. A typical home uses 14,500 kWh per year.

What happens during an electric outage?

During the day, the solar energy system should continue to generate power; however, at night only a solar energy system with battery backup will continue to provide power.

What happens on cloudy days?

Since solar energy systems require sunlight to produce electricity, the bulk of your electricity production will take place under sunny conditions. Output is directly proportional to the amount of sunlight available at any given moment. A system can generate 50-70% of its typical output under bright overcast conditions, but production will continue to diminish as less light reaches the system.
