Own it, finance it, or pay nothing upfront
Every Greenwell project — solar PV, battery storage, VFD retrofits, heat recovery, ETP optimization or lighting — can be procured three ways. You choose based on your capital position, not ours.
The equipment is the same. Only the payment structure changes.
Most factory owners delay energy projects for one reason: capital. A rooftop solar plant, a heat recovery system or a full VFD retrofit competes with machinery, inventory and expansion for the same limited funds.
Greenwell removes that competition. We deliver identical Tier-1 engineering under three procurement routes — outright purchase, structured instalments, or a zero-investment OpEx model where you buy only the energy produced. The technical scope, equipment quality and workmanship do not change between them.
The right route is decided after a free site survey, once we know your load profile, roof area, tariff category and payback horizon.
Start with the survey
Model selection is not a sales question — it's an engineering one. The free survey establishes what your site can support before any commercial discussion.
- Connected and sanctioned load review
- Roof structural and shading assessment
- 12-month tariff and demand analysis
- Indicative generation and savings model
Choose how you pay
Two CapEx variants for factories that want to own the asset, and one OpEx model for factories that want the savings without the investment.
Full payment on completion
You own the system outright from day one and keep 100% of the savings. Payment is milestone-linked and settled on commissioning.
- Full asset ownership and depreciation benefit
- Complete savings retained — no revenue share
- Financing facilitation included at no extra cost
- We support IDCOL and commercial bank applications
- Shortest payback of the three routes
Instalments over 36–60 months
Ownership from day one, spread over three to five years so the payments can be matched against the energy savings the system generates.
- Same ownership benefits as Option A
- Instalment period set between 36 and 60 months
- Payments structured against projected savings
- Preserves working capital for core operations
- Terms confirmed after site survey and credit review
Pay only for the energy you use
Greenwell finances, builds, owns and operates the plant. You buy the generated units at a fixed discount to your grid tariff for 20 years.
- No capital investment from the factory
- Tariff set 5–25% below grid, fixed after survey
- 20-year power purchase agreement
- All O&M, insurance and performance risk on us
- System transfer option at end of term
Side-by-side comparison
Indicative structure for a typical industrial rooftop project. Final terms are confirmed after the site survey.
| CapEx — Option A | CapEx — Option B | OpEx — Solar PPA | |
|---|---|---|---|
| Upfront investment | Full project cost | Structured instalments | Zero |
| Asset ownership | Factory, from day one | Factory, from day one | Greenwell, transfer option at term |
| Payment basis | Milestone-linked | 36–60 monthly instalments | Per kWh generated |
| Energy cost | Effectively zero after payback | Effectively zero after payback | 5–25% below grid tariff |
| Contract term | Project duration | 3–5 years | 20 years |
| O&M responsibility | Factory (AMC available) | Factory (AMC available) | Greenwell — fully included |
| Performance risk | Factory | Factory | Greenwell |
| Financing support | Included — IDCOL & banks | Built into structure | Not required |
| Best suited to | Strong balance sheet, fastest return | Ownership without lump sum | Capital reserved for core business |
Same plant, two very different cash positions
Project cost varies with system size, roof condition, equipment selection and site complexity, so we quote only after the survey. What does not vary is the shape of the cash flow under each route.
CapEx route
The factory funds the system — outright, in instalments, or through IDCOL and commercial bank financing that we help arrange at no additional cost. Once the payback period closes, every unit generated is effectively free for the remaining years of plant life, and the asset sits on your balance sheet with the associated depreciation benefit.
OpEx route
Greenwell funds and builds the same plant. The factory signs a 20-year PPA and pays only for units consumed, at a fixed discount of 5–25% below the prevailing grid tariff. Savings begin in the first billing cycle, with no capital outlay and no debt on the balance sheet.
Which route fits your factory?
Choose CapEx Option A if…
- Capital is available and returns matter more than liquidity
- You want the shortest possible payback
- Depreciation benefit is valuable to you
- You intend to hold the facility long-term
Choose CapEx Option B if…
- You want ownership without a lump sum outflow
- Working capital is committed elsewhere
- You prefer payments matched to savings
- A 3–5 year commitment is acceptable
Choose OpEx if…
- Capital must stay in the core business
- You want savings without technical risk
- You would rather not add debt or manage O&M
- Predictable energy cost matters more than ownership
Available across our solution lines
Procurement structure is not limited to solar. Depending on project size and savings profile, the following can also be delivered under CapEx or OpEx terms.
Common questions about OpEx and CapEx solar in Bangladesh
What does zero-investment solar actually mean?
Under the OpEx model, Greenwell pays for the entire system — panels, inverters, structure, cabling, protection and installation. The factory contributes roof space and a signed power purchase agreement. No capital expenditure appears on your books, and billing starts only once the plant is generating.
How is the PPA tariff discount decided?
The discount sits between 5% and 25% below your prevailing grid tariff. Where a project falls in that range depends on roof area and condition, load profile, how much generation is consumed on site, tariff category and contract length. The exact figure is fixed in writing after the free site survey and does not change arbitrarily during the term.
Who maintains the system under OpEx?
Greenwell does, for the full 20 years — cleaning, monitoring, preventive maintenance, inverter servicing and fault rectification, all included. Because we are paid per unit generated, underperformance costs us directly. That alignment is the point of the model.
Can we buy the system later if we start with OpEx?
Yes. The agreement includes a system transfer option, letting the factory take ownership at the end of the term or at agreed points during it. Terms are set in the PPA at signing rather than negotiated later.
Does IDCOL financing apply to CapEx projects?
It can. IDCOL offers concessional financing for qualifying renewable energy and efficiency projects, typically at rates well below commercial lending. Greenwell prepares the technical documentation and supports the application at no additional charge under Option A — you are not left to navigate the process alone.
What happens to net metering and export credits?
Systems are designed to comply with the national net metering guideline, which caps installed capacity against sanctioned load and credits exported units. Under CapEx the credits accrue to the factory. Under OpEx the treatment is defined explicitly in the PPA before signing.
