Calculating the direction, roof condition, and angle of the roof. Measuring the roof’s surface to determine the square footage available for your panels. Determining whether a roof or ground mounted system would be most appropriate. Generating a detailed engineering design and reviewing it with you. A Solar PV system can save money, create energy independence, and provide a cleaner environment.
Solar PV panels are most commonly located on the rooftop, but may also be located on the ground. When sunlight shines on the cells, it creates a direct current (“DC”). DC electricity can’t be used in your home, so inverters change the direct current into alternating current (“AC”) power, which is ideal for household use.
Electricity flows through your utility meter, which measures whether your home is consuming electricity, or producing more than you need. Solar panels will provide power to your home first. If your panels are producing more energy than your home requires, you may get credit from your local utility company. This credit can help offset some of the energy your home consumes during night time hours of no energy production from your solar panels, or during periods when your panels are not producing as much as you need. If you need more energy than the solar panels are producing, the panels will reduce the amount of energy you obtain from the utility company .. with the utility company making up the difference.
- Solar panels convert the sun’s energy into DC electricity.
- The DC electricity is fed into a “grid connected” inverter that converts it to 240V 60Hz AC electricity.
- The 240V AC electricity can be used to power home appliances.
- Surplus electricity is fed back into the utility grid.
