Dust, bird droppings, and other debris have accumulated on the surface, reducing their efficiency. Additionally, the age of the solar panels may be contributing to the decreased performance. Cleaning and maintenance are required to restore optimal energy production and efficiency.


Enhanced Efficiency: Chemical washes effectively remove dirt, grease, and biological debris, restoring optimal solar panel performance and maximizing energy production. Prolonged Lifespan: Regular chemical cleaning prevents buildup that can degrade panel materials over time, extending the overall lifespan of the solar panels. Improved Aesthetics: Clean panels not only function better but also look well-maintained, contributing to a neat and professional appearance for the installation.

The final result

Solar Heater Alkaline Wash Job Scopes:

1. Preparation

Power Off: Ensure the air conditioning system is completely powered off to eliminate any electrical hazards during the cleaning process.

2. Applying Chemical Solution

Prepare Chemical Solution: A chemical cleaner with an initial pH of 13, based on sodium or potassium hydroxide, is prepared from a concentrate following the manufacturer’s instructions.
Spray Chemical Cleaner: Evenly spray the diluted alkaline solution over the panel component to effectively break down accumulated dirt, mold, and debris.
Dwell Time: Allow the chemical solution to sit for approximately 15 to 30 minutes, enabling it to penetrate and loosen all the grime.

3. Cleaning Process

Two Technicians Required: Due to the task’s complexity and safety requirements, two trained technicians are necessary to handle the equipment and cleaning process efficiently and safely.
Rinsing: Use a water jet to thoroughly rinse the panel, to ensure maximum removal of debris and chemical residue.
To avoid scratching or damaging the surface of the panels, we use a gentle water pressure setting.
