Solar panels engineered to endure, renovate and recycle.

One silicone-gel encapsulation technology, four operational answers for solar PV plants: heat-resistant panels for extreme climates, on-site renovation of degraded panels, encapsulation laminators for manufacturers, and clean recycling at end of life.

Comparative data

Silicone gel stays stable where EVA fails.

Above 80 °C — the temperature reached daily by PV panels in deserts, tropics, and hot-industrial sites — standard EVA encapsulant begins to release acetic acid, cross-links break, and the optical layer yellows irreversibly.

Silicone gel (PDMS) holds its mechanical, optical, and chemical properties to 250 °C. That single material property cascades into every commercial outcome below: panels last in heat, can be renovated on site, and disassemble cleanly at end of life.

The technology

Silicone gel (PDMS) encapsulation for PV modules.

Most solar panels are sealed in EVA — a cross-linked plastic that yellows, embrittles and releases acetic acid as it ages, especially in heat. Silicone gel (polydimethylsiloxane) replaces it with an inert encapsulant stable to 250 °C, optically transparent, and mechanically flexible.

The same property that protects the panel in service — its softness — lets us renovate degraded modules on site every 5–10 years and, at end of life, mechanically disassemble panels at room temperature for clean material recovery.

What we deliver

Four answers for ageing solar PV plants.

We manufacture heat-resistant panels for new installations, run mobile rigs that renovate degraded plants on site, sell encapsulation laminators to panel makers building circular-economy-ready production lines, and recover materials cleanly at end of life.

Why renovation, not warranty

Field measurements show what dry tests miss.

We tested 37 utility-scale modules from real solar PV plants under wet operating conditions — fog, dew, salt mist — and compared the results to standard dry insulation tests. One in five panels failed the IEC 61215 wet limit, including five that passed the dry test.

The solar panels measured on a clinically dry afternoon are not the panels that operate at dawn. Inspection is what lets us tell a PV plant operator exactly which modules need silicone-gel renovation — and which to leave alone.
