However, it is generally proven that the ideal operating temperature for an average solar panel is 77 degrees Fahrenheit or 25 degrees Celsius. As a result, the manufacturer's performance ratings of solar panels are usually tested at 77°F (25°C) or what's called “standard test conditions.”
Not all solar panels are the same, so not all panels have the same optimal temperature. However, it is generally proven that the ideal operating temperature for an average solar panel is 77 degrees Fahrenheit or 25 degrees Celsius.
On an 80-degree day (3 degrees above ideal temperatures) solar panels would be 1.05% less efficient (.35 x 3 degrees). In this example, with a marginal efficiency loss of 1.05%, your solar panel would work at a power production efficiency of 98.95%. (Solar panels can become much warmer than ambient temperatures.)
On cold sunny days, solar panels can even thrive in winter weather, so long as they have direct access to sunlight. To recap, outside temperatures may affect your solar panels' efficiency, but this is nothing to worry about in terms of the long-term performance of your renewable energy system.
