FAQs

  • Solar panels are made with semiconductor materials like silicon that when hit by the rays of the sun can convert the light into electricity. The electricity produced is primarily direct current (DC), and most residential solar system will require additional equipment called inverters to transform from DC to AC (alternating current). This is required as most appliances and devices in residential homes run on alternating current. The inverter will distribute the AC electricity through the electrical panel to power lights, televisions, air conditioning units, etc. If your system produces more than is required for your home use, the excess electricity will go to the grid or to a back-up battery if installed.

  • The price of a solar system will vary depending on equipment installed, location, system size, local utility incentives, and the federal tax credit. The average cost to install a solar system in the United States ranges from 24,000 – 29,000 before incentives. This price can increase significantly with the addition of a battery backup.

  • A solar system’s size is based on three major factors. The electrical usage of the residence, the amount of available space to install solar, and the homeowner’s budget. Mateis Crop recommends discussing system size with a local certified installer who will consider the amount of solar needed to offset your electrical needs. They will design and install your system correctly for maximum performance based of roof orientation and the environmental factors in your area.

  • A standalone solar system connected to the utility grid is required by the local utility provider to shut down for the safety of the lineman repairing the cause of the outage. For a solar system to remain active during an outage, battery backup systems that can isolate your home and solar system from the grid are recommended or required to keep the system operational.
