Rooftop Solar
Engineered for RCC, metal-sheet and elevated roofs — maximum yield from every square foot.
Why choose Zolar for rooftop solar
Every roof is different. We design rooftop systems around your structure, orientation and shading so you get maximum generation without compromising the roof's integrity or usability.
- Uses idle roof space — no extra land required
- Keeps the building cooler by shading the roof
- Hot-dip galvanised or aluminium corrosion-proof structures
- Wind-load certified designs
- Walkways for safe cleaning and maintenance
- Leak-proof mounting methods
What's included
RCC roofs
Ballasted or anchored elevated structures with usable space underneath.
Metal-sheet roofs
Rail-less or short-rail mounts clamped to the seam — no drilling through sheets.
Elevated structures
Raised mounts that create a shaded terrace for homes and schools.
Shadow analysis
3D modelling of tanks, parapets and neighbouring buildings before layout.

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.
