Everything Solar® Everything solar is a full-service technology company designing and installing solar panel systems since 1999 in the greater Orlando area including Volusia, Orange, Seminole, Osceola, Lake, and Polk counties.Designing and installing over 12,000 solar systems in the central florida area has given us the experience to design systems that exceed current industry standards.Another reason why many people are switching to solar is a solar tax credit, incentives, and rebates. In Florida, home solar systems installed by December 2032 are eligible for a 30% federal tax credit. While installing a solar energy system can increase home value by up to 4%, it won't increase your property taxes-thanks to the Florida Solar System Property Tax Exemption. Not to mention the 6% state sales tax exemption for new installations. Unused solar power in residential properties is credited to your account so that your power bill is at net-zero by the end of the year.
