⚡ OPEX Solar Model – Zero Upfront Investment for Your Rooftop
At NetZe Eco Energy Solution Ltd., our OPEX (Operational Expenditure) model allows property owners to enjoy solar energy without paying upfront costs, while investors can earn stable, long-term returns.
Whether you are a space provider (homeowner, business, or commercial building) or an investor, our OPEX model makes solar adoption simple, transparent, and profitable.
🔹 How the OPEX Model Works
- Investor Provides Capital
- Funds the installation of solar panels, inverters, and auxiliary equipment.
- NEES manages design, procurement, installation, and ongoing maintenance.
- Space Provider Offers Rooftop Space
- No upfront payment required.
- Gains from either profit sharing or tariff discount.
- NEES as Mediator & EPC
- Designs and installs the system for maximum efficiency.
- Monitors energy production, manages billing, and ensures transparent financial reporting.
- Coordinates between investors and space providers to finalize profit share or tariff discount, usually ranging 15–25%, based on negotiation.
- Revenue Flow
- Energy generated is used onsite first.
- Excess power can be exported to the grid via net metering (if on-grid).
- Monthly revenue or savings is distributed according to the agreed business model.
🔹 Business Models for Space Providers
1. Profit Share Model
- Investors receive the majority of revenue, and the space provider earns a negotiated profit share (15–25%).
- Example:
- Monthly electricity revenue: BDT 100,000
- Profit share for rooftop owner: 20% → BDT 20,000
- Investors receive remaining 80% → BDT 80,000
- NEES ensures monthly reports, transparent calculation, and timely disbursement.
Best for: Property owners who want passive income from their rooftop without investment.
2. Tariff Discount Model
- The space provider pays a reduced electricity rate for onsite consumption.
- Example:
- Normal utility rate: BDT 10 per kWh
- Discount offered: 20% → BDT 8 per kWh
- Investor earns revenue from the remaining portion of electricity sold to the grid or the system owner.
- NEES manages billing, metering, and reporting, ensuring both parties benefit fairly.
Best for: Property owners focused on reducing electricity bills rather than earning income.
🔹 Investment Security
The NEES OPEX model is designed to protect both investors and rooftop owners:
- Triparty Agreement
- The contract is signed between NEES/Investor, the rooftop owner (space provider), and the electricity distribution company.
- This ensures legal enforceability and proper coordination for billing and energy supply.
- Advance Payment & Regular Billing
- The rooftop owner pays 3 months’ electricity bill upfront before the system starts operation.
- Regular bills are paid monthly, ensuring predictable revenue flow for investors.
- Enforcement by Distribution Company
- In case of payment delays, the electricity distribution company can legally disconnect the line according to the triparty agreement.
- This mechanism protects investor returns and ensures accountability from the rooftop owner.
- Government Support
- The Government of Bangladesh provides additional safety for renewable energy investors through regulations and incentives.
- This reduces financial and operational risks and strengthens investor confidence in rooftop solar projects.
With NEES as the EPC, mediator, and O&M provider, investors can enjoy secure returns, while rooftop owners can benefit from clean energy and flexible business models.
🔹 Example Financial Analysis
| Parameter | Value |
|---|---|
| System Size | 50 kW |
| Estimated Monthly Generation | 5,000 kWh |
| Utility Tariff | BDT 10 / kWh |
| Monthly Revenue | BDT 50,000 |
| Rooftop Owner Profit Share | 20% → BDT 10,000 |
| Investor Revenue | 80% → BDT 40,000 |
| Tariff Discount Option | 20% discount → BDT 8/kWh |
| Savings for Rooftop Owner | BDT 10,000/month |
This is a simplified example. Actual rates and profit shares are negotiated between investors and rooftop owners with NEES arranging the meeting and ensuring fair agreements.
