The amount you can save on energy bills depends on your energy consumption, the number of solar panels you have, and local electricity rates. On average, homeowners can save anywhere from 20% to 70% on their electricity bills with solar panels.

There are several financing options for solar installations, including solar loans, solar leases, and Power Purchase Agreements (PPAs).

Many governments offer incentives, tax credits, and rebates to promote solar energy adoption. These incentives can significantly reduce the up front cost of installation. Common incentives include tax credits, rebates, and net metering programs.

A photovoltaic (PV) solar system is comprised of solar panels, racks for placing the panels on your roof, electrical wiring and an inverter. From sunrise to sunset, the solar panels generate electricity (DC) which is sent to an inverter. The inverter converts the DC electricity into alternating current (AC), which is the type of electricity required for household use. The AC power is delivered directly to your home’s main electrical service panel for use by you and your family.

A microinverter is a small electronic device that sits beneath each solar panel. It’s main task is to convert direct current (DC) from your solar panels into alternating current (AC) electricity that you can use in your home or export to the grid.

All grid-connected modules with integrated inverters must comply with all the requirements and tests established in parts 1 and 2 of the UNE-206007 Report. Prior to the connection and/or contracting of self-consumption, and as indicated in section 4 of part 2, this compliance must be certified by a certification body accredited according to UNE-EN 1S0/IEC 17065.
