The cost of delay

What does a delay cost your solar power plant?

Every day a plant is not commissioned, it loses generation and revenue. Enter your project details to see an estimate.

Advanced

4,000 units per MW per day is a common average for solar plants in India. Change it if your plant generates more, for example with trackers.

Estimated generation lost
30.0 lakh units
Estimated revenue lost
₹75.0 lakh
This is an estimate based on the values you enter. Liquidated damages (LD) under your contract are extra.

FAQ

Common questions about solar installation and commissioning

What does solar installation and commissioning (I&C) include?

Solar I&C covers the site work that turns a design into a working plant: survey and layout, piling and civil works, module mounting structure erection, solar module installation, DC and AC cabling, testing and commissioning, and handover.

What project sizes do you handle?

We take installation and commissioning packages from 5 MW to 25 MW on utility-scale solar projects, and complete solar EPC for landowners and businesses from 1 MW to 5 MW.

Can you take partial scope?

Yes. We take the full I&C scope or individual packages such as civil works, piling, mechanical erection or electrical work.

Where do you work?

Across India. Our team has executed work in Rajasthan, Gujarat, Karnataka, Madhya Pradesh and Maharashtra.

How quickly can you mobilise to a new solar site?

Within 5 to 7 working days of work order finalisation, with our own team and equipment.

Do you have your own equipment?

Yes. We run our own tractors, piling augers, a JCB backhoe loader and an in-house survey team.

Do you install battery energy storage systems (BESS)?

We are building capability in battery energy storage system (BESS) installation. Share your requirement and we will discuss it with you.

Which tests do you carry out before handover?

Civil tests such as soil investigation, pile load tests, slump and concrete cube tests, galvanizing thickness and bolt torque checks, and electrical tests such as insulation resistance, string voltage and polarity, earth resistance, IV curve tracing and thermography.

Do you build solar plants for farmers and landowners?

Yes. We offer solar EPC for plants of 1 MW to 5 MW on agricultural or private land, including support with feasibility, electricity department paperwork and loan documentation.
