Solar panels are built to last for several decades. Most panels come with a warranty of 20 to 25 years, but they can continue to produce electricity even after the warranty period, albeit at a slightly reduced efficiency.

The payback period for a solar panel system varies depending on factors like the system’s cost, local electricity rates, available incentives, and your energy consumption. On average, solar panel systems have a payback period of 5 to 10 years.

The cost of a solar panel system can vary depending on the size, location, installation complexity, and the type of panels and inverters used. However, solar panel prices have been decreasing over the years, making solar installations more affordable.

Most standard solar panel systems are grid-tied, meaning they automatically shut down during a power outage to protect utility workers. However, with the addition of battery storage (like solar batteries), you can still use solar power during blackouts.

Solar panels consist of multiple solar cells made of semiconductor materials like silicon. When sunlight hits the solar cells, it excites the electrons, creating a flow of electricity. This direct current (DC) electricity is then converted into alternating current (AC) by an inverter for household use.
