Hello everyone,
In today’s post, I’d like to take a deep dive into an issue that’s crucial to understand if you’re considering solar panels for your home: the impact of inverter clipping and soiling on solar panel efficiencies.
In general, solar array for home use has drastically become the hot topic due to the increasing awareness about renewable energy. Homeowners across the globe are turning towards solar companies for a sustainable energy supply. However, when it comes to obtaining the most prudent and powerful solar solution from a solar company, understanding technical aspects such as inverter clipping and soiling becomes essential.
Inverter clipping occurs when the direct current energy produced by your solar panels is more than the maximum input size your inverter can handle. What happens next? The inverter becomes saturated and any excess energy isn’t converted to alternating current – the form used by most household appliances.
In the past, some experts have insisted that inverter undersizing may be a practical strategy to mitigate losses from soiling (dust and dirt accumulation on the solar modules, which can reduce their performance). The theory suggests that the energy loss due to soiling could be masked if it is less than the difference between the module’s energy rating and the inverter’s capacity.
However, a recent study paints a different picture. The international research team behind the study suggests that inverter undersizing alone might not be the magic bullet against soiling losses. Why is that, you ask? As time passes and your solar modules undergo natural degradation, the frequency of inverter clipping decreases. This, in turn, makes the impact of soiling more visible.
Through extensive data collection and analysis, the researchers found that while inverter clipping was more frequent in regions with higher solar radiation (Arizona, Colorado, Nevada, New Mexico, and Utah), the impact on soiling losses was minimal. They concluded that on average, clipping only reduced soiling losses by less than 0.1%.
In areas where soiling loss is more intense, the impact of clipping becomes even more restricted. For example, in solar-rich locations like Southern California and Arizona, the maximum reduction in soiling losses due to clipping doesn’t exceed 1%, even if the total losses are as high as 9% per year.
So, what does this mean for home-owners planning to engage solar companies for their energy needs? Contrary to previous beliefs, counting solely on inverter undersizing might not be an effective strategy to combat soiling loss. The researchers also recommend increasing the frequency of cleaning as an additional soiling mitigation strategy.
In conclusion, anyone considering a solar array for home use should ensure they are partnering with a competent solar company that will not only provide the best quality of solar modules but also advise you on mitigation strategies for soiling and other performance loss factors. Regularly monitoring your solar system and carrying out routine maintenance such as periodic cleanings is essential for optimum performance over time.
As the solar industry continues to evolve, so too should our understanding of these crucial aspects of solar energy production.
Let’s promote sustainable and efficient usage of solar energy by staying informed and enlightened!
