Part of the complete guide: Maintenance & performance
Kanyakumari has some of the best sun in South India, and some of the toughest conditions for equipment: sea winds, salt in the air and high humidity.
Wind
Ask for the structure's wind-load rating and the foundation details. Ballast-only mounting on a windy open roof is a red flag. Bolts should be checked once a year.
Salt
- Hot-dip galvanised or aluminium structure; stainless fasteners within a few kilometres of the shore.
- Salt-mist-tested modules.
- Wash the panels every 4–6 weeks; salt film builds up faster than dust.
Why it pays
A structure that costs 5% more but survives 25 years beats one that needs replacing at year eight. See the Kanyakumari guide.
