If you have just installed a solar system or a looking to make the investment soon, you may be wondering, “how does the weather affect the efficiency of my solar panels?” and it’s a very valid question to ask. Let’s start with the optimal weather—a sunny day in summer with no clouds in the sky. Summer days are longer, giving you prolonged periods of unaffected sunlight, and when there are no obstructions in the sky (clouds), this is when your solar system will work best.
However, as we all know, weather can be a bit unpredictable, and these optimal days won’t be around for long. So, what is the impact of other weather conditions? Cloudy days will negatively impact the system as they can block direct sunlight. Solar panels which use N-Type solar cells will perform much better in low light situations.
If you have positioned your panels under trees or are close to tall buildings, this will also impact the light reaching your system. Similarly, if they have not been cleaned, the grime and dust build-up can also affect their efficiency.
