Business Models We Offer

Business Models

 In India principally there are two major business models: 
• CAPEX – capital expenditures are provided by the rooftop owner; 
• RESCO – capital expenditures are covered by third party. 

1. CAPEX Model (One Time Investment)

 CAPEX mode is the most common business model for solar deployment in India. In this model the consumer purchases the solar system, by making 100% of the payment upfront or financing the system, often through a bank.

In CAPEX model (Capital Expenditure will be yours) you will pay the complete system cost to System Installation Company in one shot and this would be your own system. And you will be get benefited for free electricity for next 25 plus years. If you are planing to install solar for your home or small business and your instillation size is less than 100kW, you have the one and only way to get it installed is CAPEX model.

2. RESCO (Renewable Energy Service Company) Model
Under this model, a RESCO developer finances, installs, operates and maintains the rooftop solar power plant. The developer signs an agreement with the rooftop owner. The rooftop owners may consume the electricity generated, for which they have to pay a pre-decided tariff to RESCO developer on a monthly basis for the tenure of the agreement. Based on the consumption choice and requirement, the model is further divided into two types – Rooftop Leasing and Power Purchase Agreement (PPA).
A ) Rooftop Leasing Model
(Under Gross Metering) 
Under this arrangement, the RESCO developer leases the rooftop and pays a fixed lease/rental to the Land/building owner over the time of the lease period for installing the solar panels of the rooftop. The RESCO developer exports the solar energy to the utility at a predetermined feed-in-tariff (FiT) approved by the regulator.

B) OPEX Model (Pay per Unit with Power Purchase Agreement)

In OPEX model (Operation expenditure will be yours) System Instillation Company will install the complete system at their own cost on your rooftop through a 10-25 year Power Purchase Agreement (PPA) between you and installation company. After that you just need to pay per unit on monthly basis. The PPA rates (Rs. 5.50 to Rs.10) are depend on your installation size, PPA time period and your company credit rating. If you want to install solar power plant for your institute, business or industry and your installation size is above 100kW. You can go for OPEX model.

OPEX Model (Power Purchase Agreement)

You might not want to build your own solar plant, but rather buy just the electricity produced by the solar system. That way, you don’t have the upfront costs, construction and maintenance to worry about. Maybe someone else will be happy to build a solar plant on your roof (or nearby) and sell you the power through a Power Purchase Agreement (PPA). This model works typically for industrial and commercial consumers, and Indian companies have started offering it to residential customers in some cities. A PPA is a formal agreement between an electricity consumer (in this case, you) and the electricity generator (usually an investor) that specifies terms and conditions of electricity purchase. Details usually include the length of the PPA (typically 15- 25 years), the price (tariff) for the power from the solar plant and annual escalations (if any). This is also called the OPEX model.Power Purchase Agreement.

Solar Power Plant Detail, ROI & Price for 1Mw

Generate Electricity with Solar Power Plant:

Today, anyone can set-up a Solar Power Plant with a capacity of 1KW to 1MW on a rooftop space. The Govt. of India (MNRE) latest guidelines state that “Now anyone can generate electricity through solar power plant and surplus electricity can be export through Net-metering system. The installation of net-metering at the site will connect it to grid via Sate Electricity Board or Distribution Companies. Ministry of New and Renewable Energy (MNRE) and State Nodal Agencies are also providing 30%-70%  Subsidy Benefits for residential, institutional and non-profit organisations.

These regulations were long awaited. This will boost solar or green power generation across the state and encourage people to install solar Power Plants systems on their rooftops.

FAQs about 1MW solar plant

How much kilowatts or watts are in 1 megawatt?

1 megawatt is equal to 1,000 kilowatts or 10,00,000 watts.


What is the average generation of 1 MW solar power plant?

1kW solar system produces 4 units average per day throughout the year. Accordingly, 1MW solar power plant produces 4000 units per day average.


What is OPEX model?

OPEX (Operating Expenses) model is also called Power Purchase Agreement. In this model, Solar System Installation Company will install complete system at their own cost through an agreement for 10-25 years. And you will have to pay per unit cost on monthly basis.


What is CAPEX model?

In CAPEX (Capital expenditure) model, the installation cost of the solar system will be completely yours. You will have to pay the cost to Installation Company in one shot. After paying the installation cost, this would be your own solar plant.


Which model is better OPEX or CAPEX?

Both models are good. If you are a cash rich company, you should go for CAPEX. In case of shortage of investment OPEX model is better. Because if you choose CAPEX model then you will have to pay heavy amount of money in a single shot. But in OPEX model you can pay per unit cost on monthly basis for 10-25 years.
