Many locations around the world are currently experiencing extreme heat waves. As a result, the heat indices and temperature readings are hitting record highs and affecting various aspects of day-to-day life. Apart from the toll heat can take on the human body, there are also other disruptions. That said, some might wonder if these temperatures have any bearing on solar power system performance.
In truth, extreme heat does not necessarily correlate with actual hours of available sunlight. Furthermore, there is no reason to think that hot ambient temperatures will impact on the performance of photovoltaic systems. While environmental temperature may be high, there are other factors ameliorating the effect of heat on the panels. For example, the presence of cooling winds is a factor that could contribute to a system’s performance.
How does extreme heat impact on the efficiency of a rooftop solar system
According to some sources, optimal output is achieved at 25 degrees Celsius. That is the statistical industry standard temperature at which panels generally work best. Of course, that’s the temperature of the panel, not ambient temperature. That said, one can easily devise a variety of ways to determine how extreme heat impacts panel temperature.
Generally, when one goes below or higher than that figure, there is a measurable loss of efficiency. Therefore, one needs to measure each panel in order to determine exactly how much power is lost. Conversely, though, some setups and locations might still compute differently for efficiency. Nevertheless, competent solar installers should be able to assess the optimal conditions under which a particular system will function. Consequently, you will have a more precise idea of the likely performance and maintenance at particular times and situations.
In the first place, a good way to facilitate better cooling is to elevate the panels off the roof. A comparable example is when one uses a stand to lift one’s laptop a few inches off the table surface. In particular, this facilitates airflow for considerably better cooling. Naturally, this is a measure that is best done during initial panel installation.
Likewise, another solution is to add some shade to some sections of the system. Shielding components such as inverters from direct heat and sunlight helps keep them cooler and allows them to last longer. Some solar PV system owners also install fans or other custom cooling solutions to augment the cooling of their systems.
Don’t worry too much, though, about extreme heat disrupting the output from your solar panels. Fortunately, panels and PV systems today use sophisticated techniques and high-quality materials ensuring optimum function under most conditions. Manufacturers continuously improve their PV products, with new technologies and processes. As a result, solar power systems keep getting more efficient. Each system also comes with extensive guarantees for durability and performance, so you’re assured that you’re getting your money’s worth.
