Frequently Asked Questions

• How does solar energy work?

  Solar technology converts sunlight to electrical energy through either PV (photovoltaic) panels or with mirrors designed to focus solar radiation. PV is used in solar panels, which are the most common solar energy system. The energy from the sunlight is absorbed by PV cells, which excites the cells’ electrons and produces electrical energy. When paired with battery storage, the process can even generate backup power for use at night and during outages.

• What are the advantages and disadvantages of solar energy?

  Pros:

  • Renewable energy source
  • Reduced monthly electric bills
  • Simpler maintenance needs
  • Incentive programs like state and federal tax credits

  Cons:

  • Upfront installation costs
  • Weather-dependent efficiency, making climate/region something to consider

• What will a solar energy system cost?

  Solar energy systems can be a significant investment, but a large portion of these costs can be recouped as soon as the equipment has been in service for a few years. Batteries without panels can range from $12,000 to $22,000 depending on energy storage capacity, while full installation can run as much as $35,000. Schedule a quote with our Experts to find out what you need for a solar energy system.

• What is solar energy used for?

  Solar energy is ideal for solar HVAC systems on top of other appropriate equipment such as solar-powered water heaters.

• Are solar panels an appropriate choice for my home?

  The ultimate efficiency of adding solar panels to your home depends on the regional climate of where you live. Feel free to give us a call to schedule a quote and start the conversation for a solar energy installation.

• What is the process for getting a solar system?

  Our solar Experts can assist in providing information. It’s worthwhile to research if there are other programs in your state aside from the 30% federal tax credit. Finally, it’s wise to have a trusted company like Donelson Air Service Experts complete a home energy audit. An in-depth audit helps you determine how much you could save through solar panel installation when compared to local utility costs.
