Renovation of a damaged module

Gelovation of Photovoltaic Modules – Modern PV Plant Renovation

Our unique gel technology restores module insulation, extends their service life, and significantly reduces the operating costs of your photovoltaic power plant.

Service Life Extension by 5–10 years
Lower Carbon Footprint with no need to remove existing modules
Repairs Without Disassembly easy application on site
600 CZK / module test inverter boosting

We repair existing damaged panels with a unique gel technology that mechanically and electrically seals the panel and thus extends the service life by 5 - 10 years. The technology is exceptional for its easy application on site. It is not necessary to remove the existing panel. This repair is the only possible legal way to solve the problem with damaged panels without losing the subsidy purchase price per kWh. obr.: Oprava, renovace panelů

Estimate the Financial Benefits of Panel Refurbishment

Adjust the parameters to match your photovoltaic power plant and estimate the economic benefits of panel refurbishment. The calculations are based on publicly available scientific studies, professional publications, and real-world operational experience. The values used are derived from the research of Pavel Poulek et al. (Solar Energy, 2023) and from the long-term experience of Solarmonitoring s.r.o. in the field of photovoltaic panel diagnostics and refurbishment.

Why Choose Module Gelovation

Module Gelovation

Modern technology for mechanical and electrical sealing of modules.

Extended Service Life

Insulation restoration and protection against module back side degradation.

Lower Carbon Footprint

Module renovation is more environmentally friendly than replacement.

Reduced Operating Costs

A multiplier effect – extending energy production without investing in new modules.

Repairs Without Disassembly

Application takes place directly at the power plant with no need to remove the module.

Advantages of repair, panel renovation

Mechanical and electrical seal of damaged panel
Extends the life of the module by 5-10 years. Solar module repair without disassembly directly in the field.
Prevents water from flowing into the interior of the panel (damaged tedlar / frame). Repair of encapsulation using silicone gel.
Improves insulation properties. Restores the insulation state of the solar module (electrical sealing of the module).
Increases (or improves) electrical resistance. Legal repair of the panel.
Increases the strength of the back of the module and prevents it from cracking. Due to its flexibility and thermal expansion, the sealing material does not crack and adheres well to the material.
Prevents current breakdown of cells on the structure.
