Rooftop Solar Deployment in India – Overview
GRANDSOL’s core competencies helps its customers to take charge of their energy costs and stay competitive in their markets. GRANDSOL delivers substantial value to its customers by partnering with them for their Solar Energy demands & solutions for long-term.
Solar is one of the fastest growing and talked about energy generation technologies globally. Increasing awareness of climate change, energy security needs, facilitation from Government, decline in solar energy costs and emergence of new and innovative business models are some of the prime drivers for the large scale development and deployment of solar energy.
As a result, the Government of India’s target of 1,00,000 MW from solar power is realistic and eminently achievable. The 40,000 MW from Rooftop Solar (RTS) is an important step to rapidly develop the solar sector. This segment is attractive to state governments, utilities and cities, as they do not require pooling of land or separate transmission facilities. At the same time, it makes consumers into prosumers by becoming active participants in the energy sectors.
RTS Systems have huge potential in India as estimates show that nearly 70% of the building stock In India, which will be required in 2030, is yet to be constructed. The support provided by the Ministry of New & Renewable Energy through skill development programmes, financial assistance and incentives, concessional finance for developers and focused awareness programmes provides an additional impetus.
However, Solar Rooftop in many parts of the country is still at an early state, but rapidly gaining it’s momentum, thanks to solar implementation policies to central and state governments. There is a need to co-ordinate across all stake holders to help this sector achieve its true potential. There is a need to address market-related constraints that hamper smooth implementation and capacity addition.
It is important to enable market eco-system to provide further thrust to the sector and ensure its scale up in efficient manner. Therefore, substantial co-ordination of stakeholders including Regulators, Discoms, State Nodal Agencies, Banks, Urban Local Bodies, Developers / Aggregators / EPC Contractors, etc. are required for implementation of RTS Projects.

The grid connect inverter converts the DC electricity produced by the solar panels into 240V/415V AC electricity, which can then be used by the Consumer.
If a grid connect system is producing more power than is being consumed, the surplus is fed into the mains power grid to Govt. & the Govt. will adjust the same in your next electricity bill or pay you for the same.
Financing Models Of Developing Mw Scale Solar Pv Power Plants
- Capex (Capital Expenditure) Model in Open Access or Group Captive mode: In CAPEX model the End user will invest on the complete system with the EPC and this would be the End User’s own system forever. The End User will avail the cheapest cost electricity for next 25 plus years with meager O&M cost.
- Opex (Operational Expenditure) Model / BOOT (Built-Operate-Own-Transfer) Model (Pay per unit with Power Purchase Agreement): In Opex Model, the Solar Service Provider will invest on behalf of the end user with an agreement for purchasing the solar power for a differential cost for a mutually agreed fixed tenure and transfer the system to the end user after the tenures.
The above pie-chart represents a tentative breakup of utility scale solar power plants. It is clear that while there is reduction in module cost, it would take a major chunk of while setting up a power plant.
Key Advantages of Rooftop Solar
- Rooftop space is effectively utilized & green power is generated & utilized during day hours along with grid supply
- he differential of cost of Solar power @ Rs.2.30 is realized against @ Rs.6.50 for HT Industries & @ Rs.8.50 for LT & Commercial segments.
- Grid Stability is enhanced.
- Factory’s ambient temperature is reduced
- Bottomline is increased
India’s chronic energy shortage not only leads to frustrating power cuts throughout the country but also translates into individuals and companies having to spend excessive amounts on diesel generators to ensure backup power. A study carried out by The Federation of Indian Chambers Of Commerce And Industry (FICCI) suggests that 1/3 of all industrial units in the county suffer power cuts for more than 10 hours every week. The same report suggested that more than 61% companies suffered a production loss greater of than 10% due to power cuts. Solar energy either on rooftops or on available ground nearby can prove to be an astute investment providing the comfort of clean-tech energy at a cheaper rate then the prevalent diesel generators.
Rooftop Selection Criteria
The Industrial / Commercial Rooftop shall be either RCC or Asbestos or Sheet Metal Roofing. It would be ideal if the roofing is made North to South position. If it is not viable, then suitable accessories would be required to install the solar panel from north to south.
Shadow free space is mandatory, especially from East & West directions. Typically 100 Sq. feet would be required for installing 1 kWp of Solar Power.
As per TNERC policy For LT Industries, Net-Metering is applicable up to 120 kWp & for HT Industries, with Reverse-Power-Relay a maximum of 1 MW of capacity is allowed for captive consumption within premises.
GRANDSOL possess the expertise in locating the land packs as per the customer requirements and convenience, hassle freely.
