Answers to all your questions.

Residential solar systems, also called photovoltaic (PV) systems, convert sunlight into electricity by using solar panels. Solar panels consist of many small photovoltaic cells that are connected together to form a module. When sunlight hits the cells, it excites electrons and causes them to move, creating a direct current (DC) electricity. An inverter converts the DC electricity into alternating current (AC) electricity, which can be used to power homes.

There are several advantages of using residential solar panels, including:

  1. Reducing your carbon footprint: Solar energy is a clean, renewable source of energy that does not produce harmful emissions, unlike fossil fuels.
  2. Cost savings: Once installed, solar panels can save you money on your energy bills. If your solar system generates more electricity than you use, you can even sell it back to the grid.
  3. Energy independence: With solar panels, you can generate your electricity, which means you’ll be less reliant on the grid. This can be especially beneficial in areas where power outages are common.
  4. Increased property value: Solar panels can increase the value of your property and make it more attractive to buyers.

If your home is equipped with solar panels, and the panels are connected to a battery backup system, you may still have electricity during a power outage, depending on the size and capacity of your solar system. However, if you are connected to the grid and do not have a battery backup, your solar system will not work during a power outage for safety reasons.

The amount you can save on your energy bills with residential solar panels depends on various factors, including your location, the size of your solar system, and your energy consumption. However, research shows that homeowners can save between $10,000 and $90,000 on energy bills over 20 years through the use of solar panels.
