Cleaning of photovoltaic panels: practical advices

HOW TO...CLEAN PHOTOVOLTAIC PANELS. A COMPLETE GUIDE!

Yes, guys! The photovoltaic panels are to be cleaned and also periodically.

In theory, it should deal with the rain of the cleanliness of our facility, but in reality it does not.

This article will give you some tips on cleaning of photovoltaic panels.

Equipment for the do it by yourself, engagement cost for companies and rely on tips that can make a difference.

Is it necessary to wash solar panels?

The statistics suggest that the lack of cleanliness of the photovoltaic panels can cause a loss of efficiency of 15-30%.

The dust and the sand may even shorten the duration of the life cycle of the entire system.

Automated systems for cleaning of photovoltaic panels (Robot for cleaning solar panels) are convenient to use but require an initial investment that those with "only" a small domestic facility not want to deal with.

So, robots for cleaning solar systems can be cost-effective for companies.

Private individuals who want to engage themselves in the work of ordinary system maintenance can rely on our tips!

How often do you need to clean the solar panels?

The cleaning of a photovoltaic system falls within the ordinary maintenance works.

The frequency depends primarily on the position of the implant and on the needs indicated in the manufacturer's warranty.

The rate increases by:

  • proximity of a marine area (due to the presence of sand, resin, salts ...)
  • proximity to trees (for the presence of debris, foliage, resins and other tree substances)
  • proximity to an industrial area (due to the presence of soot and various residues)
  • proximity to chimney of a fireplace / stove (for the presence of soot)
  • windy areas (carrying debris, dust, dirt ...).

Another factor to consider in order to understand how often to clean the solar panels is in the frequency of rainfall.

Modern solar systems are designed to last over 30 years but only if properly maintained and inspected.

A rain may suffice to sweep away dust and debris.

But it becomes more difficult when the panel is subject to fouling, deposits of foliage or even worse, water spots that over time can permanently damage the glass.

Already, the surface of the solar panels should be treated and clear as if the glass of your favourite window.

Another problem to be faced is the implant placement: the solar residential use exploits the surface of the roof to generate energy, so solar modules to clean become difficult to achieve.

To facilitate the cleaning of the photovoltaic system, they are commercially available kits for washing solar panels that use demineralized water and / or product specific or very mild cleansers.

The demineralized water is commonly used to set up a freshwater aquarium, to load the iron or diffuser aromas.

Demineralized water is produced from air conditioners systems, however, only a few people convey it in tanks to retrieve it. Such a pity!

Cleaning of photovoltaic panels DIY

Those who rely on DIY should act in the early hours of the morning.

The early morning hours are perfect for washing solar panels: the dew deposited on the panels at night can help to "soften" grime.

A solar system located in a favorable position, should be washed few times a year.

To provide for cleaning the photovoltaic system independently, you need to have the equipment allowing the DIY.

In the market there is no shortage kit for cleaning solar panels consist of telescopic brushes, roller brushes and cleaning agents for glass surfaces.

Already, in theory would not serve a detergent for photovoltaics, it is sufficient to use a soap for glass or shiny surfaces.

The only drawback is that these soaps are too aggressive and tend to leave a residue, which on drying may leave chemical deposits.

To overcome this problem, if you use a household cleaner, remember to rinse thoroughly.

Alternatively, there is commercially available detergents that do not require rinsing because they lack persistent active substances.

Whichever product you choose, make sure it does not leave residues and therefore does not require rinsing!
