High-efficiency rooftop solar built for Mumbai housing societies and businesses.
Solis is the dedicated solar and clean energy hub of JC Apex Ventures. We handle the entire journey: from physical rooftop shadow audits and structural load design, to tiered procurement of 540W to 590W modules, elevated pergola arrays, net metering approvals with Mumbai power utilities, and PM Surya Ghar subsidies.
With over 36 years of direct utility engineering experience on our leadership team, we know exactly what BEST, Adani Electricity, Tata Power, and MSEDCL require. You get honest engineering, zero jargon, and a single point of accountability.
Key Highlights at a Glance
How we propose and execute solar projects
We follow a rigorous four-stage engineering and commercial method so there are no surprise costs, no structural hazards, and no delays in net-metering synchronization.
Site Inspection & Shadow Audit
- Physical inspection of roof slab, waterproofing, parapets, and column anchor points.
- 365-day shadow pattern study for water tanks, lift machine rooms, and neighbouring towers.
- Usable shadow-free footprint calculation to verify realistic plant capacity.
Engineering Sizing & Panel Selection
- Accurate load analysis matching annual power bills and sanction capacity.
- Tier-1 high-efficiency modules (540W to 590W mono PERC or bifacial half-cut).
- Multi-MPPT on-grid string inverters optimized for partial shade resilience.
Costing, BOS, Taxes & Subsidies
- Transparent Bill of Systems (hot-dip galvanized structures, copper DC cables, SPD arrestors).
- Blended 13.8% composite GST breakdown and PM Surya Ghar subsidy application.
- Net-metering liaisoning across BEST, Adani, Tata Power, and MSEDCL.
Specialized Solutions Execution
- Elevated Pergola structures raising solar arrays 8 to 10 feet to keep terraces usable.
- BIPV semi-transparent architectural solar glass for skylights, atriums, and facades.
- Smart EV charging hubs connected to solar distribution with resident RFID billing.
Specialized clean energy solutions
Modern Mumbai buildings have high terrace utility and distinct aesthetic demands. We engineer custom solutions that fit dense urban requirements.
Elevated Pergola Solar Structures
Traditional solar arrays occupy the floor and make terraces unusable for residents. Our elevated pergola structures lift the panels 8 to 10 feet above the roof floor on heavy structural steel or hot-dip galvanized columns.
Building Integrated Photovoltaics (BIPV)
Replace conventional roof sheets or glazing with power-generating solar glass. Ideal for skylights, atriums, entrance canopies, and contemporary building facades where standard black solar panels look industrial.
Integrated EV Charging Hubs
Turn rooftop solar generation into free vehicle fuel. We set up dedicated AC Type 2 smart chargers (7.4 kW to 22 kW) and DC fast charging points wired directly to the solar main distribution board.
Floor-Mounted Cluttered Roof vs Elevated Pergola Canopy
Drag the interactive divider to see how Solis elevated steel structures lift solar panels overhead to preserve 100% of your terrace floor for walking and society recreation.
Traditional Low Mount
Standard low metal frames mount panels 0.5m above the waterproofed slab, blocking residents from walking, gatherings, or using terrace amenities.
Solis Elevated Pergola
Hot-dip galvanized structural portal frames lift solar modules 10.5 ft overhead, leaving the entire terrace deck open for walking, recreation, and society gatherings.
Why Solis? Why Solar & Clean Energy? Why Now?
A mathematical, regulatory, and spatial breakdown of why urban rooftop solar is Mumbai's highest-yielding infrastructure investment, and how our elevated pergola engineering eliminates the historic compromise between clean electricity and terrace lifestyle.
Why Solis & JC Apex
Zero Terrace Loss & 36+ Years Utility Authority
- Multi-Surface Spatial Multiplier: We lift solar arrays 8 to 10 feet overhead on heavy hot-dip galvanised structural frames, keeping 100% of the terrace floor completely open for walking, morning yoga, and community gatherings.
- Direct Utility Engineering Authority: Under Director Jitendra Chavan (36+ years inside Mumbai utilities), we handle all liaisoning with BEST, Adani Electricity (AEML), Tata Power, and MSEDCL with zero bureaucratic delay.
- Coastal Storm Wind Rating: Engineered for 150 km/h gusts with chemical epoxy base anchors, diagonal truss bracing, and integrated rainwater perimeter gutters that prevent terrace leaks.
- Statutory FSI & Fire Clearance: Fully compliant with BMC DCPR 2034 Regulation 37 solar rooftop FSI exemptions and Chief Fire Officer (CFO) mandatory 1.5m perimeter fire-escape walkways.
Why Solar & Clean Energy
Hedge 6% to 8% Tariff Inflation & Harvest Albedo Gain
- Permanent Power Tariff Hedge: Common-meter electricity for elevators, water pumping, and corridor illumination inflates at 6% to 8% every year. Rooftop solar caps energy costs under Rs 2.10/unit for 25+ years.
- Bifacial Albedo Multiplier: Elevated pergola arrays allow reflected sunlight from cool-roof white terrace floor membranes to hit the rear side of bifacial glass panels, capturing 12% to 22% additional daily generation.
- Urban Micro-Utility Synergy: Direct coupling with EV chargers and architectural BIPV solar glass converts a dead concrete roof into a self-sustaining asset that adds tangible resale valuation to building flats.
- Measurable Environmental Impact: A standard 55 kWp residential array mitigates over 68 tons of CO2 annually, offsetting the carbon emissions of approximately 1,100 mature urban trees.
Why Act Now
PM Surya Ghar Subsidies & Local Grid Transformer Quotas
- PM Surya Ghar Central Grants: Unprecedented direct subsidies: up to Rs 78,000 for individual homes and Rs 18,000/kW (statutory ceiling up to Rs 90 Lakhs for 500 kW) for Group Housing Society common meters.
- Rapid 3.2 to 3.8 Year Payback: Net project capital outlay is fully recovered in under 4 years via direct monthly bill credits, yielding over 21 years of pure dividend generation.
- Distribution Transformer Caps: Under MERC regulations, local distribution transformers have a 70% to 80% maximum solar injection ceiling. Once neighborhood transformer quotas fill up, new net metering applications are refused.
- Rising Raw Material Costs: Structural steel, hot-dip galvanizing, and copper cable costs trend higher annually; executing today locks in current turnkey EPC pricing.
