❓ Frequently Asked Questions
How do solar panels generate electricity?
Solar panels convert sunlight into electricity using photovoltaic (PV) cells, which create an electric current when light hits the semiconductor material.
What factors affect how much power a solar panel produces?
Power output depends on sunlight intensity, panel efficiency, the angle/orientation of the panels, temperature, shading, and local weather conditions.
Are solar panels effective in cloudy or winter weather?
Yes, they can still generate electricity in cloudy weather, but production is lower. In winter, sunlight may be reduced, though colder temperatures can help panel efficiency somewhat.
What is the difference between grid-tied and off-grid solar systems?
Grid-tied systems connect to the utility grid (often with net metering). Off-grid systems rely on batteries and other equipment to store energy for when the sun isn’t available.
How long do solar panels typically last?
Many solar panels are warranted for 20–25 years and can continue producing electricity beyond that, usually with gradual efficiency degradation over time.
