While sunny warm days seem to be best for solar energy generation, silicon PV panels can become slightly less efficient as their temperature rises. This is due to a property of the silicon semiconductor, which means that these class of Solar PV panels have a ‘negative coefficient of temperature’: this means they produce less energy when really hot.
Current is the rate at which electricity flows through the system. Temperature affects solar panel voltage and current. As temperature increases, it the amount of energy a panel produces. This is due to an increase in resistance—high temperatures slow the speed of the electrical current.
The angle at which solar panels are installed significantly influences the amount of sunlight they can capture. Properly adjusting the panel angle ensures that the panels receive the maximum solar radiation throughout the day, leading to increased energy production and improved system efficiency.
This difference plays a major role in answering the question of whether or not solar panels work less at certain temperatures. The number one (often forgotten) rule of solar electricity is that solar panels generate electricity with light from the sun, not heat.
If the solar panel’s temperature goes up to 35°C (or 95°F) energy production will reduce by 3.6%. To give some additional context, you can multiply the percentage of power lost at a specific temperature by the solar panel’s wattage to determine how much wattage is lost. For this, let’s use a 320W panel.
It’s a range for the temperatures at which a panel can produce at its best. Here’s an example. A 200-watt panel at 20 degrees Celsius (68 degrees Fahrenheit) might only produce 180 watts when the panel reaches 45 degrees C (113 degrees F). The ideal day for a solar panel is actually cold, sunny and windy.
