3 business ideas / models to advance on solar energy in India

CAPEX  model

The most common business model for solar deployment in India today is to simply sell either a complete plant (by an EPC company) or individual components (such as modules or inverters) to an end customer who owns the plant. The consumer pays 100% of the PV system cost upfront. This model, sometimes referred to as the CAPEX model, is pursued by the vast majority of solar companies, such as TATA Power Solar, EMMVEE Photovoltaics or Moserbaer. The term “CAPEX” is the capital expenditure or expenditure on the total cost of a power plant.

This model can be improved, for example, by developing specific, standardized solar kits (Ready to install kits which consists of all components required for installation) for specific customer types, for example in the range of 1-50 kWp. Consumers can purchase these kits from suppliers and get them installed by the local community installer. Such a model is followed by various companies like TATA Power, First Solar, among others.

Renewable Energy Service Company (RESCO) Model

Under a RESCO model, a third party investor comes in to invest into a plant on the consumer’s rooftop and sells solar power to the consumer. There is no investment required from the consumer. If solar power is viable the consumer can benefit from savings from the start. The investor and the consumer agree on a “per kWh” tariff and timeline of a power purchase agreement (typically between 15-25 years). Operations, repair and maintenance of the system would usually be carried out by the project owner and not the consumer.

This model becomes more feasible for larger project sizes as the transaction costs would prevent an investor from investing into small plants (unless many small plants can be easily bundled together). Thus, the model is applicable particularly to commercial and industrial consumers in Delhi, for example, who might not be willing or able to invest upto INR 2.5m (EUR 38,461; USD 50,000) for a 100 kW system, but are ready to commit to an attractive long-term power purchase agreement.

Local Micro Utility Model

Third-party solar power developers could rent roof space from building owners in a designated area, install PV systems and sell the power generated to the rooftop owners, or the DISCOMs at a pre-negotiated tariff. The project developers would particularly target those consumers who might not have the resources or would be unwilling to invest in rooftop solar. Developers can offer building owners a lease income on their rooftop space.

This model allows project developers to bundle rooftop space in a community and thereby minimizing the legal, commercial and technical transaction costs by increasing the size of individual plants. This makes the model especially useful for deployment of solar for residential consumers.
