Solar

Commercial & Industrial (C&I) Solar

Commercial and industrial (C&I) consumers looking to cut power costs or move toward renewable supply have a different set of constraints than utility-scale developers: available roof or land area on-site, existing electrical infrastructure, and a power purchase structure that fits the facility's consumption pattern.

We work with industrial consumers to assess on-site solar potential and coordinate qualified EPC partners for rooftop or ground-mount C&I installations, alongside open access and group captive routes where a facility's own site isn't sufficient.

Rooftop or ground-mount on-site

Rooftop systems depend on the roof: its structural capacity, remaining service life, orientation, and how much of it is clear of skylights, vents and plant. A roof due for replacement in a few years usually needs to be addressed before panels go on.

Facilities with spare land on their premises can consider ground-mounted systems instead, which avoid structural constraints but compete with any future expansion plans for that land.

Matching generation to consumption

The value of on-site solar depends on how much of its output the facility uses directly. Plants with a strong daytime load typically absorb most of the generation; facilities with evening or night-heavy load rely more on how the local metering regime treats exported energy.

Net metering, gross metering and export limits are set by state regulations and discom procedures and change over time. Check the regime applicable to your connection category before sizing a system.

Ownership models

Under a capital-expenditure model, the facility owns the system and benefits directly from the savings. Under a third-party (RESCO or PPA) model, an investor owns and operates the system and the facility pays for the power it uses.

The trade-off is between upfront capital and long-term savings on one side, and lower commitment with a share of savings on the other. We set out both against the facility's actual bills rather than generic assumptions.

What We Do Directly

  • On-site assessment of available roof or land area and existing electrical infrastructure
  • Coordination between the facility, EPC partners and, where relevant, discom or open access processes
  • Advisory on captive vs. third-party ownership and power purchase structures
  • Project coordination through contracting and execution

Delivered Through Qualified Partners

  • Engineering, procurement and installation of rooftop or ground-mount systems
  • Structural assessments for rooftop installations
  • Metering, protection and grid-interconnection works
  • O&M once the system is commissioned

We coordinate execution through qualified EPC and delivery partners rather than building or manufacturing in-house.

Process

  1. 01Review the facility's current power consumption, tariff and available site area
  2. 02Assess technical suitability for rooftop or ground-mount solar
  3. 03Recommend a structure: captive ownership, third-party PPA, or open access
  4. 04Coordinate EPC partner selection and contracting
  5. 05Track execution through commissioning
