Go Solar Without Paying Upfront: PowerMore's Solar On Lease Model
Zero CAPEX solar lets businesses go solar without upfront cost. Here's how it works, and how PowerMore's new Solar On Lease model takes it a step further.
For most businesses, the idea of going solar has always made financial sense. The upfront cost is what stops the conversation before it starts. Zero CAPEX solar exists specifically to remove that barrier, and PowerMore is taking it a step further with a new model: Solar On Lease.
What Is Zero CAPEX Solar?
Zero CAPEX solar refers to any arrangement where a business adopts rooftop solar without paying for the system upfront. Instead of buying the plant outright, a developer finances, installs, owns, and maintains the system, while the business pays for the value it receives, either as electricity consumed or as a fixed periodic payment.
This differs fundamentally from the CAPEX model, where a business purchases and owns the system from day one, claiming full electricity savings and tax depreciation benefits, but carrying the entire upfront cost itself.

The Structures Behind Zero CAPEX Solar
Zero CAPEX isn't a single model, it's a category covering a few distinct structures, each suited to different business needs:
The OPEX / RESCO Model
Under a standard Power Purchase Agreement, a Renewable Energy Service Company (RESCO) owns the plant indefinitely, and the business pays a fixed per-unit tariff for electricity consumed, typically ₹3.50-5.50 per kWh against grid tariffs of ₹8-12 per kWh, translating into savings of roughly 30-50% depending on the facility's consumption profile. Ownership never transfers to the business under this structure.
Lease-To-Own Structures
Some zero CAPEX models are built around a defined ownership handover: the developer owns and maintains the plant during the lease term, and once that term ends, ownership transfers to the business at zero additional cost. This gives businesses the immediate cash-flow benefit of zero CAPEX today, with a genuine ownership outcome built into the contract from the start.
Pay-As-You-Save / Rental Financing
A newer structure gaining traction across the Indian C&I market ties repayment directly to a fixed monthly rental, rather than a per-unit electricity tariff, offering more predictable, budget-friendly payments regardless of how much the system actually generates in a given month.
Standard OPEX/PPA Vs Solar On Lease: A Quick Comparison
| Feature | Standard OPEX / PPA Model | Solar On Lease | | --- | --- | --- | | Ownership During Term | Retained by the developer for the full contract period | Retained by the developer for a fixed, shorter term | | Payment Structure | Pay per unit (kWh) of electricity consumed | Pay a fixed monthly rental, regardless of generation output | | Ownership At End Of Term | Typically stays with the developer unless a separate buyout clause is negotiated | Transfers to the business automatically at zero additional cost | | Contract Duration | Typically 15-25 years | Typically 5 years or shorter | | Savings Potential | 30-50% versus grid tariffs, tied to per-unit rate | Predictable fixed cost, converting to full savings once ownership transfers | | Best Suited For | Businesses wanting the lowest possible monthly cost with no ownership goal | Businesses wanting an eventual ownership outcome without upfront capital | | Regulatory Framework | Governed by state DISCOM net metering regulations and the Electricity Act, 2003 | Governed by the same net metering framework, with ownership transfer terms defined contractually |
Financial Benefits Of Zero CAPEX Solar
Zero CAPEX solar removes the upfront-cost barrier and directly addresses two concerns every business finance team cares about: cash-flow pressure and rising electricity tariffs.
Immediate Savings Without Capital Investment
- No Upfront Cost — Nothing is paid to design, install, or commission the system.
- Preserved Capital — Funds stay available for inventory, operations, or expansion, instead of getting tied up in equipment.
- Positive Cash Flow From Day One — Since the solar tariff or rental typically sits below the equivalent grid cost, savings begin the moment the system is switched on, not after a payback period passes.
Protection Against Rising Electricity Tariffs
- Locked-In Rates — A zero CAPEX PPA fixes the solar tariff for the full contract term, insulating a business from unpredictable grid pricing.
- Shielded From Tariff Hikes — That locked rate protects a meaningful share of a business's energy spend from rising DISCOM tariffs, fuel surcharges, and new levies, costs that grid-dependent businesses absorb in full.
- Predictable Budgeting — With only a modest, pre-agreed annual escalation built into most contracts, finance teams can forecast energy costs with far more confidence than relying on grid tariffs alone.

Who Zero CAPEX Solar Is Built For
Zero CAPEX solar suits nearly any high-consumption site, a large distribution centre, a manufacturing unit, or a retail complex. The objective stays the same across all of them: lower monthly energy costs and a more reliable power supply, without tying up capital to get there.
Factories And Industrial Buildings
Systems are sized to cover daytime machinery loads, offsetting the most expensive peak-hour grid purchases.
Offices And Commercial Complexes
Mid-sized systems offset lighting, HVAC, and equipment usage during daylight hours, cutting operating costs while strengthening sustainability credentials.
Warehouses And Distribution Centres
Large, unobstructed roofs allow for scalable systems that can offset a significant share of total energy consumption.
How Zero CAPEX Solar Improves Cash Flow
Zero CAPEX solar strengthens a business's cash position in two distinct ways:
- Avoids New Debt — There's no need to take on a loan or use business credit to acquire the system, preserving borrowing capacity for other investments.
- Immediate Bill Reduction — Since the solar rate typically sits below the grid rate, total monthly electricity cost decreases right away, with the difference staying in the business rather than going toward a loan repayment.
How A Zero CAPEX Project Actually Gets Sized
Before any installation happens, a proper assessment comes first:
Consumption Analysis
The last 12 months of electricity bills are studied to map usage patterns, tariff structure, and peak demand hours.
System Design
The proposed system, whether a 100 kW commercial rooftop or a 500 kW industrial installation, is matched to the facility's actual operational needs and available roof space.
Savings Projection
A transparent forecast lays out the fixed tariff or rental, projected savings, and how the arrangement compares against expected future grid costs.

Questions buyers ask us.
No, there's no upfront payment. You just pay a fixed amount every month for 5 years.
Yes. Once the 5 years are over, the solar plant becomes fully yours at no extra cost.
PowerMore handles installation and upkeep throughout the lease period, so you don't have to worry about it.
No. Unlike a regular rental or PPA, this is only for 5 years, after that, the plant is yours.
This depends on the exact terms of the lease agreement, it's best to check the exit conditions with PowerMore before signing.
It depends on your budget. If you don't want to pay a large amount upfront, Solar On Lease lets you start saving immediately and still end up owning the system in just 5 years.
Solar On Lease was built for businesses that want the certainty of eventual ownership without the upfront capital commitment CAPEX requires; zero CAPEX today, full ownership in five years, with predictable monthly payments the whole way through.
