A string inverter is a type of solar inverter that connects multiple solar panels, or strings, in series. The 3% designation refers to the efficiency specification related to the inverter's performance—indicating that the inverter can convert 97% of the direct current (DC) generated by the solar panels into alternating current (AC) that can be used in homes and businesses. The remaining 3% accounts for energy losses that occur during this conversion process.

Although most of the components in installing solar panels are relatively simple, if you’re not a fan of being on a roof or not comfortable working with electricity, solar panel installation can be complicated. For instance, tying the panel wiring into the home can be complex for the average DIYer and should be left to the professionals.

Most solar installations also qualify for federal tax credits and incentives, which can significantly reduce the upfront costs. As of 2023, the federal solar tax credit allows homeowners and businesses to deduct a percentage of the total system cost from their federal taxes, making solar energy more accessible and financially viable.

Beyond maintenance, one of the most attractive features of solar energy is the potential for substantial savings on electricity bills. Homeowners can often reduce their energy expenses by 50% or more, depending on their energy usage and the size of the solar system installed. Additionally, many regions offer net metering programs, allowing homeowners to sell excess energy generated back to the grid, further enhancing savings.

As of 2023, the average cost of 400-watt solar panels typically ranges from $250 to $500 per panel. This price can fluctuate based on the factors mentioned above.
