Y2 Solar project case study

3 kW Solar in Dashrath Puri near Palam-Dabri under BRPL

Mrs. Priti Bala's Dashrath Puri home near Palam and Dabri had a shared rooftop, so the solar system had to use only the momty and water-tank area. Y2 Solar planned a compact 3 kW BRPL-connected system that shaded the tanks and fit precisely around tight rooftop constraints.

Location: Dashrath Puri, near Palam and Dabri, Delhi
Capacity: 3 kW
System: Residential on-grid solar on shared momty and water-tank area

3 kW Solar in Dashrath Puri near Palam-Dabri under BRPL

What we assessed

A system shaped by the actual site.

Shared rooftop constraints and agreement from other floor owners
Precise structure placement around water tanks on the momty area
5 x 620 W N-type TOPCon panel layout with string inverter integration
BRPL subsidy, GBI and net-metering documentation sequence

Project outcome

A practical, evidence-led recommendation.

The 3 kW system was fitted precisely above the shared momty and water-tank zone, generating solar power while also helping shade the tanks during Delhi summers.

Project record

What was actually installed

Customer: Mrs. Priti Bala
Location: Dashrath Puri, near Palam and Dabri
DISCOM: BSES Rajdhani Power Limited (BRPL)
System size: 3 kW
Panels: 5 nos. 620 W N-type TOPCon panels
Inverter: Premier/Sungrow string inverter
Subsidy received: Rs 1,08,000
Current GBI: Approx. Rs 1,100/month for 5 years

Shared rooftop constraint

The rooftop was shared with other residents, so the customer could not use the full terrace. The viable area was the momty and water-tank zone, which required a compact design and agreement from other floor owners.

Why the tank area worked

The customer convinced the other floor owners that solar above the momty area would also shade the water tanks, helping keep stored water cooler during summer. This turned a constraint into a practical shared benefit.

Compact 3 kW design

Y2 Solar installed 5 nos. of 620 W N-type TOPCon panels with a Premier/Sungrow string inverter. Because the momty was covered with tanks, the structure and panel placement had to be measured and executed precisely.

BRPL subsidy and GBI

The project was installed under BSES Rajdhani Power Limited territory. Mrs. Priti Bala received Rs 1,08,000 as subsidy and is receiving approximately Rs 1,100 per month as GBI for five years, based on the project information shared.

Project photos and planning

Project photos and planning evidence.

The 3 kW panel layout was placed over the momty and water-tank area so the shared rooftop could remain available to other residents.

The structure shades the tanks, supporting the customer's argument that the installation would help keep everyone's stored water cooler in summer.

The inverter and protection equipment were installed neatly on the momty wall, with routing planned around the constrained rooftop service area.

Project FAQ

Questions this project answers.

Can solar be installed only above a momty or water-tank area?: Yes, when the structure, access, shading, tank clearance and wiring routes are planned carefully. The available area may limit system size, so a site survey is important.
Is rooftop solar possible on a shared terrace?: It can be possible when ownership, roof rights, resident consent, access and DISCOM documentation are clear. In this case, the installation was limited to the momty and tank area to respect shared rooftop use.
What panels were used in this Dashrath Puri project?: The 3 kW system used 5 nos. of 620 W N-type TOPCon panels with a Premier/Sungrow string inverter.
What subsidy and GBI did this project receive?: The customer received Rs 1,08,000 as subsidy and is receiving approximately Rs 1,100 per month as GBI for five years, based on the project details shared.
