Commercial Solar EPC & Project Planning
Compare commercial solar proposals on engineering, equipment and execution scope, not capacity alone. Solwiz Energy helps businesses plan a solar project around useful daytime demand, installation constraints, monitoring and long-term maintenance.

- Factory solar
- Institutional solar
- EPC and O&M planning
Commercial solar starts with load analysis
We review electricity bills, operating hours, sanctioned load, roof area, transformer capacity, and future expansion before recommending capacity. This avoids oversizing and keeps ROI assumptions realistic.
| Input to prepare | Decision to review |
|---|---|
| Bills and operating schedule | Capacity and useful self-consumption |
| Roof drawings and condition | Mounting assessment and access |
| Connection and electrical details | Protection, cable routes and upgrade scope |
| Shutdown and access constraints | Installation sequence and responsibilities |
Commercial project support
Solwiz Energy supports engineering, component selection, installation sequencing, safety documentation, monitoring, and maintenance planning for commercial solar sites.
Compare a written scope before procurement
Request named equipment models, mounting and electrical specifications, installation inclusions, exclusions and handover documents. Separate structural review, utility coordination and site upgrades from the base price. Review savings assumptions and finance terms independently; a low price is not a like-for-like comparison without scope.

FAQs
Which businesses can install commercial solar?
Factories, warehouses, offices, schools, hospitals, shops, hotels, and institutions with suitable roof or open space and meaningful daytime power consumption can evaluate commercial solar.
Do you serve outside Kerala for commercial solar?
Yes. Commercial service coverage includes Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, Telangana, and Maharashtra for suitable projects.
How is commercial solar ROI calculated?
ROI depends on system cost, tariff, generation, self-consumption, finance cost, maintenance, and applicable tax or depreciation treatment. We present assumptions clearly for review.
