Following the Start of Autumn
which literally signifies the "beginning of autumn"
the season presents unique conditions for PV power stations
Despite shorter daylight hours
the autumn season typically experiences less rainfall
The autumn with clear sky and crisp air
provides superior solar irradiance and comfortable temperatures
These optimal conditions
are ideal for PV module operation
leading to peak power generation efficiency
Why not summer?
Despite the strongest solar irradiance and longest daylight hours
summer is not necessarily the season with the highest power generation
In fact, it may even underperform compared to spring or winter
Why is this the case?
Under Standard Test Conditions
(STC, which is typically defined as being 1000W/m2 of irradiance, with a cell temperature of 25°C)
the rated output power of PV module
decreases as the actual operating temperature
exceeds 25°C
The power degradation rate caused by temperature change
is determined by the module's temperature coefficient (usually negative)
Higher operating temperatures
directly lead to a reduction in module output power
thereby affecting power generation
In general
for every 1°C increase in temperature
the output power of N-type monocrystalline modules
decrease by 0.28% of the baseline value
Therefore, due to high temperatures, summer impacts the efficiency of modules and inverters
leading to increased failure rates. Consequently, overall power generation may decrease, making it not the season with the highest power output
A good generation season deserves good returns
Entering the peak season for PV power generation
choosing a high-quality module with high energy yield
high reliability, and assured service
is a crucial foundation for generating more power and achieving better returns
