The one goal that we have at Green Pulse Energy is to save you as much money on your energy bills as possible and one of the biggest ways you could do this is by installing Solar PV.
However, our services and advice simply don’t stop after an installation; we know it is vital that your solar panels are maintained and cleaned on a regular basis.
Rates of Efficiency Over Twenty Years (Without Cleaning)
Over the course twenty years your solar panels will drop in efficiency by as much as 20%, little by little every year.
This is mainly due to the build of grime and dirt on the surface of the panels that blocks some of the sunlight that would have otherwise been absorbed by the solar panels.
Rates of Efficiency Over Twenty Years (With Cleaning)
With a once annual clean of your solar panels the collector efficiency can maximised.
When you compare the rates of efficiency between a clean solar panel and a dirty solar panel; the clean one runs 21% more efficiently.
Bear in mind…
these figures apply to residential properties, rates of efficiency on commercial properties are usually higher due to their placement on much larger and higher roofs. Although, the same rules still apply; clean solar panels produce the most electricity and provide the biggest paybacks.
In fact, it is much more critical that commercial solar panels are cleaned on a regular basis as they are even more susceptible to dust and dirt due to their placing in large open fields or high roofs where there is little to no shading.
Why Other Methods of Cleaning Don’t Cut It
Of course, all modern solar panels have self-cleaning technology but this cannot clean your panels at a fast enough rate.
Even rain water will add to the muck on your panels. Imagine your solar panels are the same as your car windscreen, if left long enough there will be a layer of dust, dirt etc. despite any rainfall that may have occurred.
Is the Cost of Cleaning Worth It…
The cleaning of your solar panels is relatively low cost and with specially designed equipment its common practice to clean solar panels from the ground rather than climbing onto the roof. With that in mind, yes, the minimal cost of maintenance is worth the extra saving you’ll make by having solar panels working at their full potential.
So, make sure you take good care of your solar panels to ensure you’re getting the best out of your investment.
