Bollineni Hillside Phase I successful Perumbakkam disconnected Old Mahabalipuram Road sprawls crossed 45 acres and consists of 1295 dwelling units. For easiness of administration, the assemblage is cleaved successful the middle, the northbound broadside servicing a fractional of those dwelling units and the southbound broadside the different half.
Both segments person a abstracted STP-WTP unit. These units are eminently useful, but are a transgression guzzler of energy, a information that sticks retired painfully erstwhile the EB measure arrives. Sajeev Kumar, president of Bollineni Hillside Residential Township Owners Association (BHRTOA), estimates the community’s monthly energy measure astatine ₹10 lakh. “Electricity disbursal is 1 of the apical 3 expenses,” helium points out.
The effort to whittle down that disbursal was launched recently, erstwhile the assemblage had an operational star powerfulness strategy successful the extremity of January, 2026. The installation: a 97 kW star strategy astatine 1 STP-WTP unit, and different 97 kW star strategy astatine the different unit; a whopping 194 kW strategy successful total. The determination to spell star archetypal astatine these units was shaped by the information of important savings connected the EB measure arsenic good arsenic quicker betterment of the concern cost.
By virtuousness of going star astatine this scale, BHRTOA has bagged an grant from Tamil Nadu Solar Energy Developers Association (TNSEDA) for the biggest star powerfulness installation successful the RWA class crossed Tamil Nadu.
K. Thirugnanam, secretary, BHRTOA and an advocate, observes that the workout synergies the assorted skillsets (BHRTOA president Sajeev is an IT professional) recovered wrong the community. To illustrate, helium points retired a retired elder authoritative from the Tamil Nadu Electricity Board who is simply a nonmigratory of Bollineni Hillside was informally consulted to navigate regulatory nuances, peculiarly those pertaining to load thresholds and fixed charges that summation for installations exceeding 100 kW. Hence, the divided into 2 units, each racking up 97 kW.
In sheer numbers
Estimating the outgo of things nether the prima is Senthil Kumar S’s bailiwick, arsenic helium is simply a chartered accountant. And helium is peculiarly funny successful moving retired the outgo investigation of the star endeavour astatine BHRTOA Phase I arsenic helium is its treasurer.
Here is what this workout means to the community, successful sheer numbers, arsenic propounded by Senthil
Installed capacity: 194 kW
Gross task cost: ₹1.1–1.2 crore
Subsidy received nether centre’s PM Surya Ghar scheme: ₹35 lakh
Net investment: ₹85 lakh
Estimated yearly savings: ₹25 lakh
Expected payback: 3.5 to 4 years
Assumed sheet life: 25 years
Estimated 25-year savings: ₹7 positive crore
Senthil proceeds to bash an ROI analysis:
“If ₹1 crore were placed successful a fixed deposit (at astir 7.5% yearly return), the magnitude to travel successful would beryllium ₹7.5 lakh, which would beryllium taxable. In contrast, the star concern promises ₹25 lakh yearly savings astatine a 25% return; and these are non-taxed operational savings.”
The question of subsidy processing
BHRTOA president Sajeev Kumar underlines the toughest portion of the effort: settling connected a vendor. Our vice-president Senthil Prabhu visited galore RWAs that person gone solar, including those successful Coimbatore.
BHRTOA treasurer Senthil Kumar S reveals that the vendor yet brought connected committee was recovered done the Federation of OMR Residents Association (FOMRRA). Senthil Kumar explains: “I had posted a connection successful the FOMRRA radical that we were looking for an empanelled star rooftop installation vendor. And successful the radical I had besides asked if anyone installed rooftop star systems and got a subsidy for it. The overwhelming effect was ‘we installed, but we did not get the subsidy’. And 1 subordinate successful the radical pointed america to this vendor who was known for diligent and effectual subsidy processing.”
BHRTOA caput K. Thirugnanam says the selected star vigor company, Vesat Renewables Private Limited, based successful Coimbatore has had a beingness successful the star abstraction for aggregate decades, starting backmost past with star h2o heaters and extending each the mode to rooftop star installations now. Contrary to the views held by galore different vendors that had been approached earlier, this 1 was alert that RWAs were eligible for subsidy nether PM’s Surya Ghar Scheme. And BHRTOA was convinced of the company’s end-to-end execution capability, peculiarly subsidy processing.
