Solar Panels Love Sunshine—But Not Extreme Heat
Solar panels work by converting sunlight (not heat) into electricity. This means that even on cooler sunny days, panels can still generate significant energy. However, like any electrical component, high heat can slightly reduce efficiency. Most solar panels operate best at around 77°F (25°C), and for every degree above that, performance may dip slightly.
In East Texas, where summer temps often hit the mid to upper 90s, this heat loss is relatively minor—especially when offset by longer daylight hours and clear skies. The result? Consistent and powerful solar output all summer long.
Performance in High Temperatures: What You Can Expect
While heat can reduce panel efficiency by around 0.3% to 0.5% per degree above optimal temperature, today’s solar systems are designed to withstand high temperatures. Most modern solar panels are tested to perform in environments well above 100°F, which makes them ideal for East Texas homes and commercial buildings.
Additionally, professional installation ensures adequate airflow beneath your panels, keeping them naturally ventilated and preventing heat buildup on your roof.
