Power of solar panels

Solar panels in 2025 typically produce between 390 and 460 watts of power each, which is sufficient to run household appliances like TVs and microwaves1. For a typical home, 16 to 25 solar panels may be needed to meet energy demands1. Additionally, solar panels designed for domestic use generally produce 250-400 watts, enough to power a refrigerator for an hour2.
