Renovation of a damaged module
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. 
- price from 24 EUR / pc
- accepting orders from 80 pcs
- maintaining the purchase price per kWh

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. | |
