Due to the inclined position of solar panels, they are heavily prone to bird droppings and an accumulation of typical dust and dirt that does not get off with only rain. This decreased the amount of light striking the panel and thereby reduces its working efficiency. As the estimated energy numbers reported by solar panel manufacturers and installers are based on the optimum performance of clean solar panels, this accumulation of dirt and grime can undesirably affect the panels’ capacity to meet those forecasts. So it is important to clean solar panels to safeguard and maintain your investment.


While solar panel cleaning in the US is comparatively new, in other regions of the world solar panel cleaning has been in use for a long time. Early followers of the technology soon came to know that if their solar panels were not cleaned frequently, they would not operate at their optimum performance. According to a study done in the USA, sometimes solar panel cleaning is not necessary in some cases, but it is demonstrated that solar panel cleaning is of immense value in California.
Several market studies conducted across the globe have revealed that timely and proper cleaning of solar panels increases their efficiency. The reports also ascertained that proper solar panel cleaning in Elk Grove frequently notices considerable increases in solar panels on agricultural sites, of up to 30%. This has been verified by participants who have forwarded numbers to prove solar panel maintenance in Roseville has augmented the output and efficacy of their collection.
The clearest indication that your solar panels require cleaning is when you notice a reduction in PV system performance. It’s normal for there to be regular, weekly, or periodic vacillations in solar power output. But protracted and unpredicted reductions in output are an indicator that something is not on the right track. PV panel cleaning is the simplest and cheapest of all corrective steps – which is why most people begin here first. If more radical intervention is needed, you may need to invest in solar panel upkeep to reinstate modules to previous production levels.
Some homeowners and industrial players plan periodic cleanings throughout the year – based on local scenarios:
- Cleaning panels after rain makes a lot of sense in northern climates.
- Solar panel cleaning is quite normal during the end of the autumn season when the falling of tree leaves stops.
- It is also common in late spring when pollen counts begin to reduce again.
- Those who live in or near hot sun regions in California or Arizona might plan solar panel cleaning during the arid times of the year when dust accumulation hampers system performance.
Which occurrence to pick for your solar panels depends on you. But if you’re not making the utility bill savings you were expecting, cleaning your solar panel could help increase performance. This is particularly true if you reside in areas with extreme levels of dust, pollen, foliage, pollution, or snow.
The Conclusion
Bird droppings aren’t the elements that effortlessly wash off with strong rain – denoting solar panel cleaning may be inescapable. The same becomes true for PV modules installed horizontally. Flatter solar panels are known to invite more dust, and therefore, need more recurrent washing.
