AgroPV Water Softening Agent
Treat Hard Water Without Affecting Crops or Soil
AgroPV Water Softening Agent (AWS) is a biodegradable solution designed to treat hard and very hard water used in the cleaning of agrivoltaic (AgroPV) installations.
Chemitek’s AgroPV Solutions are the first and only range developed and independently tested specifically for AgroPV plants, and AWS ensures effective water treatment while preserving crops, soil, and surrounding ecosystems.
Hard water used in solar panel cleaning can leave limescale deposits and mineral residues on modules, reducing transparency and accelerating re-soiling. AWS works by capturing mineral ions such as calcium and magnesium, preventing these deposits and ensuring a spotless finish after cleaning.
Unlike conventional water softening products, AWS has been tested for agricultural environments, ensuring compatibility with plant development and soil conditions while maintaining optimal photovoltaic performance.
Tested and Approved for AgroPV Systems
AgroPV installations require cleaning solutions that are not only effective but also safe for agricultural environments.
AgroPV Water Softening Agent has been independently tested to ensure:
- Compatibility with seed germination
- Compatibility with plant growth
- Ecotoxicity assessment for agricultural environments
- Biodegradable formulation
- Certified as safe for photovoltaic modules and crops by independent laboratories
These tests confirm that AWS can be safely used in agrivoltaic installations where solar panels coexist with crops and agricultural activity.
Based on a Life Cycle Assessment (LCA) performed according to recognised standards, AGROPV Water Softening Agent is a CO₂ negative product. By replacing conventional, resource-intensive water treatment processes, it reduces overall emissions and offsets the impacts associated with its production.
Key points:
✔ CO₂ negative product
✔ Avoids approximately 3.4 kg CO₂ eq. per kg of product
✔ Offsets production impacts through operational benefits
✔ Reduces reliance on processes such as reverse osmosis
✔ Improves water-use efficiency
✔ Contributes to more sustainable resource management
How It Works
AWS reduces water hardness by capturing mineral ions present in hard water, preventing the formation of limescale stains and mineral residues on photovoltaic modules.
The product acts within approximately 20 minutes when added to a water tank. For real-time water softening, AWS can also be applied using a dosing pump and dynamic mixer (e.g., Dosatron).
It can be used together with other Chemitek cleaning products when required.

This product was funded through the AGROPV@INNOV project – Development of Innovative and Sustainable Solutions for the Cleaning and Protection of Solar Panels in AgroPV Systems, under the Business R&D Incentive System of Portugal 2030 (PT2030).
The project focuses on the development of biodegradable and non-phytotoxic formulations to maximize energy efficiency without compromising crop safety.
FAQs
AWS is not a cleaning product. It is a biodegradable solution designed to treat hard and very hard water used in AgroPV cleaning. It reduces water hardness by capturing calcium and magnesium ions, preventing mineral spots and limescale deposits.
Water used in solar panel cleaning often contains dissolved minerals that can leave stains and deposits after drying, affecting module appearance and accelerating re-soiling.
In agrivoltaic installations, water treatment is critical to ensure cleaning remains safe for crops, soil, and agricultural environments.
Hard water contains a high concentration of dissolved minerals, mainly calcium and magnesium. When used for cleaning photovoltaic panels, it can leave limescale stains and mineral residues after drying.
Yes. The product has been independently tested to confirm:
- Compatibility with seed germination
- Compatibility with plant growth
- Ecotoxicity assessment for agricultural environments
- Biodegradable formulation
These tests confirm safe use in agrivoltaic systems.
Yes. It has been specifically developed for agrivoltaic environments and tested to ensure it does not interfere with crop development or soil conditions when used as recommended.
Dilution depends on water hardness:
- Very hard water: 1:500 to 1:1000
- Hard water: 1:1000 to 1:2000
- Medium/soft water: higher dilutions possible
For precise values, refer to the technical datasheet.
When added to a water tank, AWS typically acts within 20 minutes.
For tankless systems, real-time softening can be achieved using a dosing pump and dynamic mixer.
Yes. AWS is compatible with other Chemitek Solar products and can be used alongside cleaning agents.
