They work in both conditions. While production is highest under direct sunlight, solar panels can still generate electricity on cloudy or rainy days using diffuse light, though at a reduced efficiency .

A standard PV system includes: Solar panels (modules that capture sunlight), an inverter (converts DC to AC), racking/mounting equipment (secures panels to roof or ground), and wiring/electrical connections. A battery is optional for storing excess electricity .

Solar panels typically last 25 years or more, often with a manufacturer's warranty guaranteeing 80% of original capacity at the 25 year mark . The inverter has a shorter lifespan (10 - 15 years for string inverters, 20 - 25 for microinverters) and may need replacement once during the system's life .

No, unless you have a battery storage system. For safety reasons (protecting utility workers fixing lines), grid-tied solar systems are required to automatically shut down during an outage . With a battery system and a "smart switch," you can use stored solar energy during an outage .

The payback period typically ranges from 4 to 7 years, depending on electricity prices, system cost, available incentives, and how much solar energy you use directly . Other factors affecting ROI include your facility's electrical usage, local power costs, and system size .
