Solar EPC
Turnkey Engineering, Procurement & Construction — one accountable partner from survey to switch-on.
Why choose Zolar for solar epc
Our EPC practice takes complete ownership of your solar plant: detailed engineering, tier-1 procurement, safe construction, testing and grid synchronisation. You get a single contract, a single point of accountability and a plant engineered for 25+ years of bankable generation.
- Single-window responsibility from feasibility to commissioning
- PVsyst-based yield simulation and shadow analysis
- Structural design certified for local wind zones
- Tier-1 modules and inverters with OEM warranties
- Quality checks at every milestone with photo documentation
- DISCOM liaison, net metering and CEIG approvals

Questions? We've got answers.
Everything you need to know about going solar — costs, subsidy, approvals and maintenance.
For homes, an on-grid system typically costs ₹55,000–₹70,000 per kW before subsidy, depending on brand, structure height and site conditions. Commercial and industrial systems cost less per kW thanks to scale. Use our solar calculator for an instant estimate, then book a free site assessment for an exact quote.
Residential consumers get ₹30,000 per kW for the first 2 kW and ₹18,000 for the 3rd kW — up to ₹78,000 for systems of 3 kW and above. Special-category states and UTs receive higher amounts. Housing societies can also claim support for common facilities. We file and track your subsidy end to end.
Roughly 80–100 sq. ft of shadow-free area per kW. A 5 kW home system needs about 400–500 sq. ft. Elevated structures let you keep using the terrace underneath.
Homes typically recover their investment in 3–5 years after subsidy, and commercial users in 3–4 years thanks to higher tariffs. With panels lasting 25+ years, you enjoy two decades of nearly free electricity.
No — for safety, on-grid inverters shut down when the grid fails so no power flows back to linemen. If you need backup, choose a hybrid system with batteries, which keeps critical loads running automatically.
Tier-1 modules come with a 25–30 year performance warranty and typically degrade only ~0.5% a year. Inverters usually last 10–15 years.
