Enabling Smart Energy for 89 Flats with 210+ kW Solar
Rooftop solar for a single flat is simple. Scaling it across an entire residential society, however, is a different league altogether. With 89 flats, multiple towers, shared infrastructure, and dozens of independent homeowner decisions, the challenge becomes exponentially more complex—one that most installers prefer to sidestep. But at Shri Siddheshwar Helix in Vemali, Vadodara, Sunbuy didn’t just take it on—they engineered a scalable, future-ready blueprint for community-wide solar adoption.
- 210+ kW - Total Installed Capacity
- 89 - Residential Flats Connected
- 10.7 kW - Common Area System
“The real achievement here wasn't the installation — it was turning 89 individual decisions into one coherent energy system.
What Made This Project Different
Most residential solar projects treat each flat as a standalone installation—resulting in fragmented adoption, inconsistent performance, and underutilized rooftop space. Sunbuy redefined this approach at Helix by designing a unified, society-wide energy system—unlocking efficiency, equity, and long-term value.
- Society-first design: A centralized energy architecture optimized rooftop usage across all towers, rather than limiting planning to individual flats.
- Dual-benefit structure: The project delivers savings at two levels—net-metered systems for individual homes and a dedicated 10.7 kW installation powering common areas like lifts, lighting, and water pumps.
- Equitable distribution: Rooftop allocation was structured fairly across all units, eliminating first-mover advantage and reducing inter-resident friction.
- Future-ready technology: High-efficiency TOPCon panels were selected to ensure superior performance and durability over the long term.
- Built-in financial flexibility: Tailored financing and EMI options lowered the entry barrier, enabling wider participation across the society.
The result is not just a solar installation—but a cohesive, scalable model for residential energy transformation.
Outcomes
At Shri Siddheshwar Helix, Sunbuy executed a coordinated, society-wide solar rollout—delivered in phases with minimal disruption and consistent quality.
- ✓ Measurable monthly bill reduction for residents
- ✓ Lower common-area electricity expenditure
- ✓ Enhanced property value for solar-enabled flats
- ✓ Full ROI visibility for every homeowner
- ✓ Replicable model for group solar adoption
- ✓ Reduced carbon footprint across the society
In Their Words
““Sunbuy did a really good job with the installation. We can clearly see the reduction in our electricity bills now. Overall, it has been a very beneficial and satisfying experience.” — Resident, Shri Siddheshwar Helix
The Bigger Picture
Shri Siddheshwar Helix is more than a completed project—it proves that scaling residential solar is a design and coordination challenge, not a logistical one. When planning, fair allocation, and financing align, adoption follows naturally. It now serves as a benchmark for housing societies across Gujarat, showing that group solar at any scale is both practical and achievable.
