Architectural BIPV, the engineering disciplines behind every plant, and the five commercial models you can build under.
01BIPV · Architectural solar
Building-integrated PV replaces conventional cladding and glazing with modules that generate, so architecture and energy stop competing for the same surface.
For architects, BIPV is a design decision as much as an energy one. We start at concept, colour, transparency, mullion coordination, structural glazing, so it reads as a façade, not panels bolted on.
Toughened glass-glass laminates with encapsulated cells, engineered for façade loads, fire and weather performance, and a 25-year generating life as a building surface.
IEC 61215 / 61730Modules coordinated with the curtain-wall grid: mullion spacing, spandrel and vision zones, concealed DC routing and junction access designed with the façade consultant.
Curtain-wall coordinatedSelectable cell colour, opacity and pattern let the façade read as glass, stone or a custom finish, while daylight transmission is tuned for the spaces behind it.

Good economics come from getting the engineering right: sizing, structure, electricals, yield and commercials. Adding more panels fixes none of them. Eight disciplines sit behind every plant we build.
Your bills, your roof, a bankable generation figure, before you commit a rupee.
Bill · Load · SiteRoof capacity and wind load to IS 875, with a mount that respects your building’s warranty.
IS 875 · Wind loadSLDs, cable and protection sizing, earthing and lightning protection, built for uptime.
SLD · Protection · EarthingSimulation-grade yield with 3D shading, soiling and temperature losses. A realistic annual number.

Buy the plant outright, finance it, let a developer own it, own it after a term, or draw power from an off-site plant. The hardware is the same, what changes is how you pay for it.
You invest once and own the plant from day one. Every unit it generates is yours, and so is the entire saving.
Upfront full cost · ownership day one · payback 3–5 yrs (indicative)
| Model | Upfront | Ownership | Best for | Payment | O&M |
|---|---|---|---|---|---|
| CAPEXOwn the asset | UpfrontFull system cost, on your books | OwnershipYours from day one | Best forCapital-ready owners seeking maximum long-term return | PaymentOne payment; the plant then runs at near-zero cost for 25+ years. Payback typically 3–5 yrs indicative | O&MAnnual AMC with Goggles Energy |
| Loan / EMIOwn it, financed | UpfrontMargin money upfront; the balance may be arranged through third-party lending partners, subject to eligibility and lender approval | OwnershipYours from day one | Best forOwners who want the asset without the upfront cheque | PaymentFixed EMI over 3–5 yrs, typically covered by the solar saving indicative | O&MAnnual AMC with Goggles Energy |
| RESCO / PPAZero capex | Upfront₹0, developer finances & builds | OwnershipDeveloper during the PPA | Best forSavings without capital outlay or asset responsibility | PaymentPer-unit solar tariff below your grid rate, 15–25 yr PPA | O&MIncluded, developer carries performance risk |
| BOOTOwn after term | Upfront₹0 during the PPA period | OwnershipTransfers to you at term end | Best forEventual ownership without investing now | PaymentTariff below grid; asset transfers after 10–15 yrs | O&MDeveloper during PPA; AMC after transfer |
| Open accessBeyond the roof | UpfrontVaries, captive, group captive or third-party | OwnershipDepends on the structure chosen | Best forMulti-MVA sites scaling beyond rooftop capacity | PaymentWheeling + open-access tariff, attractive for large consumers depending on state regulations, charges and load profile indicative | O&MSplit or bundled; Goggles coordinates across assets |
