Sea-Shield zonnepanelen: duurzaamheid voor uw dak

Dubbele POE-inkapseling

Sea-Shield gebruikt dubbele POE-inkapseling aan beide zijden van de zonnecellen om de penetratie van vocht te verminderen en de interne elektrische structuur te beschermen. De hoge elektrische weerstand van het materiaal helpt ook potentieel-geïnduceerde degradatie (PID) te beperken, wat betrouwbare energieopwekking ondersteunt in vochtige maritieme omgevingen.

In LONGi's material testing

The dual-POE encapsulant demonstrated approximately 76% lower water vapour transmission and 2.5 times higher volume resistivity compared with conventional EVA.

Marine-resistant glass

Sea-Shield features specially developed corrosion-resistant glass with a dense protective barrier designed to withstand prolonged saltwater exposure. The protective surface helps limit glass corrosion and preserve light transmission in demanding marine environments.

higher light transmittance than conventional glass

In LONGi's comparative testing

Sea-Shield glass maintained approximately 2% higher light transmittance than conventional glass during exposure to a 5% sodium chloride solution at 35°C.

Corrosion-resistant aluminium frame

Sea-Shield features a corrosion-resistant aluminium frame with a protective oxide layer approximately 50% thicker than that of a conventional frame. The reinforced surface protection helps reduce corrosion caused by salt spray, supporting long-term frame durability in marine environments.

In LONGi's comparative testing

The Sea-Shield frame showed no visible surface abnormalities after 60 days of salt mist exposure, while the conventional frame exhibited substantial surface corrosion. The Sea-Shield frame also passed a separate 192-hour CASS corrosion test.

Enhanced junction box and connector sealing

Sea-Shield features an enhanced sealing system for its junction box and connectors, including silicone-rubber O-rings and additional waterproof and dustproof stoppers. These protective elements help prevent seawater ingress and reduce corrosion risks at sensitive electrical connections.
