Most of us would assume that the stronger and hotter the sun is, the more electricity our solar panels will produce. But that’s not the case. One of the key factors affecting the amount of power we get from a solar system is the temperature. Although the temperature doesn’t affect the amount of sunlight a solar cell receives.

As the temperature rises, the output voltage of a solar panel decreases, leading to reduced power generation. For every degree Celsius above 25°C (77°F), a solar panel''s efficiency typically declines by 0.3% to 0.5%.
Solar panel output is often expressed in watts (W) or kilowatts (kW), and the price you pay for your solar system is typically determined by its power output. The wattage of a solar panel represents its theoretical power generation capacity under ideal conditions, including abundant sunlight and optimal temperatures. This wattage is calculated
According to the manufacturing standards, 25 °C or 77 °F temperature indicates the peak of the optimum temperature range of photovoltaic solar panels. It is when solar photovoltaic cells are able to absorb sunlight with maximum efficiency and when we can expect them to perform the best.
Solar panels convert sunlight into electricity, but not all light is turned into power. The efficiency of a solar panel typically ranges between 15% and 23%, although lab tests have pushed these numbers above 40%. This means that a significant portion of sunlight is used effectively to generate electricity.

Temperature regulation is essential to maintain the efficiency of solar panels. Excessive heat can reduce the performance of solar cells, leading to a decrease in the amount of electricity generated. The decrease in efficiency is primarily attributed to the increased resistance of the materials used in solar panels as temperature rises.
The objective of this research is to identify the temperature effect on the solar photovoltaic (PV) power generation and explore the ways to minimize the temperature effect. The photovoltaic (PV) cells suffer efficiency drop as their operating temperature increases especially under high insolation levels and cooling is beneficial.
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.
One of the primary temperature management techniques used in solar panels is passive cooling. This technique utilizes the natural convection and radiation processes to dissipate excess heat from the panels. Passive cooling methods include the use of heat sinks, which are designed to absorb and transfer heat away from the solar cells.
