Sola Tecs Manuals & FAQ

Do solar modules really become so dusty that the system performs noticeably worse?

Indeed. Soiling-related yield losses are frequently undervalued. Reports based on actual experience indicate that yield losses range from 10% to 30%. The need for routine cleaning of solar power and photovoltaic systems is no longer a secret. Almost all systems need to be cleaned at some point in their lifetime. To determine the extent of soiling, it makes sense to use a white cloth to clean a portion of a module

What results in PV system soiling?

Low roof pitch: Rain no longer “washes” dust and debris off the modules because of the low roof pitch. Particularly on the lowest edge, a layer of dirt builds up.
Farms: the use of heavy machinery has a negative impact on farms, and soiling is a problem for poultry and feeding stalls.
Bird droppings: these stains are the most tenacious kind and have the ability to etch modules.
Pollen settles on the modules in the spring, along with other environmental factors like soot, car emissions, leaves, tree needles (resin), moss, algae, lichens, lime, and many more.

Additionally potential soiling hazards include leaves and tree needles if there are trees close to your system. Alternatively, visualize a busy road where automobile exhaust fumes build up on the modules. Moss eventually spreads to the module frames’ edges.

Is it beneficial to regularly clean solar modules?

Very absolutely. Profits are wasted more easily in the photovoltaic industry than in any other! There isn’t a sector where calculating earnings and losses can be done so fast and effortlessly. Measuring only prior to and following cleaning. Yield losses in certain systems can reach 30%. These systems produce 30% less electricity, which results in 30% less feed-in compensation. The highest performance and yield are only provided by clean modules.

Can the modules be harmed by the solar cleaning process?

No. Because the SOLA-TECS cleaning systems are made specifically for this function, they cannot harm anything. Conversely, though. The materials are long-lasting and are shielded from the partially corrosive dirt particles thanks to residue-free washing. Lime stains cannot occur since demineralized water is utilised, and the “pure water” absorbs dirt more readily. Clean without using any chemical detergents and without the need to squeegee and dry the surface! To demineralise the water, we utilise DI resin filters.

What kind of material is utilised for cleaning?

The ideal method is to use rainwater; if this isn’t possible, demineralize domestic water using a DI resin filter. Water that has been demineralized is devoid of all minerals, ions, and salts. Reverse Osmosis, DI resin filter, or an ion exchanger, is used to generate demineralized water, pure water.

How often is it necessary to clean a solar system?

This question lacks a universally applicable solution. It may vary based on where the system is located. From a budgetary perspective, every two years makes sense in rural areas. Large systems on agricultural buildings or in close proximity to farms should typically be cleaned once a year; however, if stables have severe soiling, cleaning twice a year may boost yields even further.
