Solar for factories and process plants
The strongest economics in Indian solar, and it is not close. A high industrial tariff meets a load that runs straight through the solar day, so nearly every unit generated is consumed on site rather than exported at a lower rate.
Key figures
3–5 yr
Typical payback
Before accounting for depreciation. Faster than residential despite receiving no subsidy, because the tariff displaced is higher.
~90%
Self-consumed
A process load consumes as the array generates. Very little is exported, so very little is settled at a lower rate.
25 yr
Performance warranty
Module output is warranted for 25 years. The roof is the constraint, not the panels.

Questions people ask
Can you install over a running mill?
Yes. Structure and panel work proceeds above the production floor with appropriate containment; only the final electrical connection needs a planned shutdown, usually a few hours scheduled around your calendar. We have done exactly this on spinning mills in Palladam and Rajapalayam.
Will the existing roof structure take the load?
That is what the structural assessment in the survey determines. Most industrial sheeted roofs will, with the right mounting and load distribution. Where they will not, we say so, reinforcing a roof is a legitimate line item, not something to discover after installation.
What about safe access for maintenance?
FRP walkways and handrails are part of scope on most industrial installations. An array nobody can safely reach is an array nobody cleans, and a dirty array quietly loses you a tenth of your generation.
Do you handle CEIG approval?
Yes. Electrical inspectorate approval, DISCOM sanction and commissioning formalities are included, along with as-built documentation for your records and your auditors.

That plus a roof plan is enough for a first-pass sizing and a realistic payback. If it does not stack up for your site, we will tell you.
