Learn MoreSolar energy system losses directly impact the overall solar panel's performance, energy efficiency, and power output. Various factors affect the power production of a solar PV system. The solar module characteristics as well as solar system design, orientation, and configuration all ensure the output of a solar energy system.
As efficiency decreases, a value needs to account for energy loss both during the design process and over the PV system's lifetime. A solar cell loses 0.5 percent of its output for every 1 degree C above the STC-rated temperature of 25 degrees C. That is why this is the most important loss in the energy system.
Any solar PV issue with these factors becomes the reason for solar energy system losses. However, the best solar design and installation services reduce the risk of system loss issues in a solar panel system.
One of the biggest system losses is caused by high temperatures — for every 1°C above 25°C the output from a solar cell drops by 0.5%. Researchers continue to look at ways to reduce thermal losses, such as increasing air circulation.
As such, whenever a solar cell or panel does not receive sunlight — due to shading or nearby obstructions — the entire installation generates less overall solar power. This is known as PV system shade loss. Shading can come from a variety of sources, including:
Aurora Solar's Ultimate Guide to PV System Losses includes basic solar performance concepts like the effect of tilt, orientation, and shade on production metrics.
