Additionally, the geographical location plays a vital role in the amount of sunlight your panels will receive. Areas with abundant sunshine will generate more energy, while cloudy or shaded regions may produce less. To estimate solar panel output, consider using a solar calculator or consulting a professional installer who can provide a tailored assessment based on your location and roof characteristics.

Below, you can find resources and information on the basics of solar radiation, photovoltaic and concentrating solar-thermal power technologies, electrical grid systems integration, and the non-hardware aspects (soft costs) of solar energy. You can also learn more about how to go solar and the solar energy industry. In addition, you can dive deeper into solar energy and learn about how  the U.S. Department of Energy Solar Energy Technologies Office is driving innovative research and development in these areas.

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.
