How often should the resin in the bottle be renewed to ensure optimum filtration?

PURE WATER resin is a highly effective water filtration system specifically designed for the maintenance of solar panels.
It's important to first understand that pure water filtration depends on the hardness of the water. Water hardness, or Hydrometric Title, is expressed in TH (°f) and indicates the concentration of magnesium and calcium ions in the water.

The harder the water, the more filtration is required by the resin tank, and the more frequently the resin must be replaced. In France, the average water hardness is around 15°f.

On average, a 25-liter bottle of resin needs to be replaced after filtering 2,000 liters of water.
A summary table is available to help easily determine the resin replacement frequency for a 25-liter tank.

The filtration bottles offered by QLEEN BY GUIALTO are equipped with a sensor that indicates the resin’s filtration level, allowing timely replacement once it is exhausted.
This ensures that photovoltaic cleaning remains effective over time, helping maintain the profitability of solar panel installations.

Owners of photovoltaic panels: are you sure you're getting the best return?

Why Use Proper Cleaning Equipment for Your Solar Panels?

Investing in specialized cleaning equipment is essential to ensure the longevity and performance of your photovoltaic panels.

Regular solar panel cleaning helps maintain optimal energy output. Dirt, dust, pollen, and other residues can significantly reduce the productivity of your system, negatively impacting the profitability of your solar installation over time.

Proper maintenance with the right tools not only ensures energy savings but also extends the lifespan of your solar equipment.

Why do photovoltaic panels work less well when they are dirty?

The performance of solar panels can be affected by dirt that accumulates over time. Like any equipment, it is important to maintain your installation over the long term to maximize profitability!

  • Dirt creates a barrier between the solar panel and the sunlight
  • The solar panel captures less light
  • The reduction in productivity of the installation can reach up to 15% within the first year! This represents a significant financial loss for the operator over the years if proper maintenance is not carried out.

Why buy solar panel cleaning equipment?

  • You can clean your solar panel installations quickly after a particularly bad spell of sand, for example, and therefore limit the loss of yield from your installation over time.
  • You can carry out regular cleaning of your installation yourself, or you can have your own equipment if you have it cleaned by a specialist company.

Which solar installations are particularly worth watching?

  • Above or next to agricultural buildings
  • Near major roadways
  • In the south of France, where sand-laden rain is more common
  • Close to industrial sites or business areas

Why use telescopic carbon poles to clean solar panels?

Why choose a carbon telescopic pole for solar panel cleaning?

Carbon fiber is a material known for its exceptional strength and light weight. Commonly used in high-performance fields like professional cycling for manufacturing ultra-light bike frames, it offers superior durability and handling.

When applied to cleaning poles, carbon allows the creation of an ultra-light, strong, and durable telescopic pole ideal for solar panel cleaning. Operators can easily reach high or hard-to-access surfaces while remaining safely on the ground. This makes the job much safer, more comfortable, and less physically demanding—even during long cleaning sessions.

QLEEN by GUIALTO offers high-quality carbon telescopic poles designed for professional solar panel and glass surface cleaning. Thanks to their lightweight and ergonomic design, they provide effortless cleaning performance—perfect for professionals seeking efficiency, safety, and long-term profitability.

How often should the resin in the bottle be renewed to ensure optimum filtration?

Understanding Pure Water Filtration and Resin Replacement Frequency

It’s important to know that Pure Water filtration depends on the hardness of the water. Water hardness, also known as the Hydrometric Title, is measured in TH (°f) and indicates the concentration of magnesium and calcium ions in the water. The harder the water, the more intensively the resin cartridge filters, and the more frequently the resin needs to be replaced. In France, the average water hardness is approximately 15 °f.

On average, the resin in a 25-liter bottle needs to be replaced after filtering about 2,000 liters of water. The chart below provides an easy reference to determine the optimal resin replacement frequency for a 25L bottle.

Resin replacement chart for 25L bottle

All QLEEN By GUIALTO water filtration machines are equipped with a sensor that shows the current filtration level of the resin. Resin should be replaced when the sensor indicates:

  • 50 microsiemens for window cleaning
  • 100 microsiemens for solar panel cleaning

* All QLEEN machines consume approximately 200 liters of water per hour.
** As a guideline, a 25-liter resin bottle can clean around 250 square meters in one hour using a Rotaqleen Vario rotary brush system.

Can cleaning brushes be used for purposes other than cleaning solar panels?

Qleen-By-GUIALTO cleaning equipment offers the advantage of being highly versatile. Depending on the brush fibers, the same equipment can be used to clean verandas and pergolas of a house, warehouse cladding, your car, or even your boat. The brush fiber color code helps identify specific uses. White fibers are specially designed for large glass surfaces, cars, boats, and bay windows. Blue fibers, which are firmer, are intended for cleaning warehouse cladding, terraces, walls, and more. Red fibers are specifically dedicated to cleaning solar and photovoltaic panels.

The same equipment can therefore be very versatile and serve different purposes and applications by simply using different sets of brushes with varied fiber textures.

Some specialized cleaning companies, for example, offer farmers or industrial clients solar panel cleaning services as well as cleaning of warehouse walls or agricultural buildings. With the same equipment, cleaning companies can amortize their investment and travel costs by providing a more comprehensive and extended cleaning service to their clients.
