GRANDSOL is an ambitious and rapidly growing start-up organization ventured in 2016. GRANDSOL is a diversified company sprung from it’s group of companies which had strongly established in coal mining, automobile, agriculture & logistics industries.

GRANDSOL management’s key stake holders are backed with more 24 years of wide industrial expertise in Solar Photovoltaic & Power Electronics industry with strong business acumen to enable the deployment of Solar Power across the country.

Solar Power is sustainable & renewable source of power which are naturally available in abundance unlike fossil fuels. Solar Power is eco-friendly, reduces the carbon foot-print, prevents melt down of polar and thereby it’s an obvious choice as an alternative power. Economic viability is now allowing it to be an augmentative power, but in near future it has the potential to become an 100% reliable power source when combined with other renewable & non-renewable energy sources that is also combined with high life & high efficiency battery technologies.

GRANDSOL had prioritized Solar Power, by sensitizing it’s need for the present and future market and intended to provide impeccable solar solutions to the chosen markets, where plenteous solar solutions providers who were sub-standard solar solutions which had ruined the market in the past.

GRANDSOL had prioritized Solar Power, by sensitizing it’s need for the present and future market and intended to provide impeccable solar solutions to the chosen markets, where plenteous solar solutions providers who were sub-standard solar solutions which had ruined the market in the past. GRANDSOL differentiates and cut’s itself from the rest and provide premium and standard solutions that fits within the customer’s expectations in terms of technical & commercial aspects as well.

GRANDSOL had successfully achieved its installations of over 56 MW in Ground Mount, 350 kWp of Rooftop Solar On-Grid Power Projects & 3500 LPD of Solar Water Heaters. GSPL had committed itself by delivering substantial value to it’s customers, by ensuring 100% Commitments Vs Deliverables, deploying European Standards, Pro-active Preventive Maintenance helps them to achieve Lowest TCO (Total Cost of Ownership), High MTBF (Mean Time Between Failures), Low MTTR (Mean Time To Repair) and thereby ensure their peace-of-mind.

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.




Rooftop Solar Deployment in India – Overview

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.




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.
