The Story in Brief
Bollineni Hillside Phase I in Chennai began operating two 97 kW rooftop solar systems at its sewage treatment and water treatment units in late January 2026. The 1,295-home community has received the Tamil Nadu Solar Energy Developers Association award for the largest solar installation in the residential welfare association category in Tamil Nadu, The Hindu reports.
The project cost Rs 1.1 crore to Rs 1.2 crore, with Rs 35 lakh received through the PM Surya Ghar scheme. The association’s net investment is about Rs 85 lakh. It estimates annual savings of Rs 25 lakh and expects to recover the cost in 3.5 to four years. The panels are expected to last 25 years.
The Indian Opinion
The easy narrative is that rooftop solar is an automatic money-saver, while another blames subsidies for making projects unworkable. This case shows a less dramatic answer: careful vendor selection, technical advice and a large common electricity bill made the numbers work. The association’s projections still need to survive maintenance costs, generation shortfalls and tariff changes. The clearest test is whether annual savings reach the promised Rs 25 lakh over the next few years.
