The location and climate of your home in Missouri play a significant role in solar panel efficiency. Solar panels are most efficient when they receive direct sunlight, so regions with more sunlight throughout the year, like southern Missouri, tend to have higher solar panel efficiency. However, even in regions with some cloud cover or occasional shade, modern solar panel technology can still generate substantial electricity. Solar installers will typically assess your specific location to optimize panel placement for maximum sunlight exposure. Snow and dirt can temporarily reduce efficiency, but these issues can be resolved with occasional cleaning or by installing panels at an angle that encourages shedding.
