Coastal solar · Konkan and Goa

Solar that survives the sea.

Near the coast, a cheap system can rust, leak and lose output within a few years. Built right, it lasts 25. This is our speciality.

What goes wrong

Five coastal threats, and the fix for each

Salt mist eats ordinary steel and aluminium frames, connectors and junction boxes. Near the sea, corrosion class C4–C5 is normal.

Fix: Hot-dip galvanised or marine-grade structures, stainless fasteners, and panels tested for salt mist (IEC 61701).

Four months of cloud and rain cut output and test every seal and cable.

Fix: Honest yearly estimates that include the monsoon dip, IP65+ enclosures, drip loops and raised inverters.

The west coast sits in high wind zones under IS 875 (Part 3).

Fix: Structures designed for your wind zone with proper anchoring, not just weighted down.

Warm, wet air speeds up potential-induced degradation and inverter faults.

Fix: PID-resistant modules, good earthing and ventilated inverter placement.

Coconut and mango trees move shade across roofs through the day and the seasons.

Fix: A 20-minute shade walk at 9 am and 3 pm, and layouts that avoid the worst strings.
