Electricity is one of the biggest running costs for factories, offices, hospitals and housing societies. Solar energy gives a chance to produce your own power from your rooftop or open land, reduce monthly bills and lower your carbon footprint at the same time.
India has become a global leader in solar power. As per the Ministry of New and Renewable Energy, India’s installed solar capacity crossed 100 GW in early 2025*. The government has set a target of 500 GW of non-fossil fuel capacity by 2030*, and the PM Surya Ghar Muft Bijli Yojana aims to put rooftop solar on one crore homes*. These numbers show that solar is no longer an experiment; it is the mainstream choice.
But a solar plant is a 25-year investment, and many projects fail to give the promised savings because of poor planning. Common mistakes include wrong system size, shading from nearby structures, low-quality panels or inverters, weak mounting structures and not understanding the electricity tariff and net-metering rules of your state.
This is why independent technical consultancy matters. Sanjay Desai of Trefoil provides technical consultancy for solar electricity generation projects. The process begins with understanding your energy use: monthly bills, working hours, load pattern and future expansion. Then the site is studied for roof strength, direction and shadow.
Based on this study, a practical and economically viable solution is suggested. It may be an on-grid rooftop system for a factory that works during the day, or a hybrid system with batteries for a site that faces power cuts. The goal is the best return for the money spent, not the biggest plant.
Benefits of a well-designed solar plant include lower electricity costs, protection from future tariff increases, a better image with green-minded customers and a real contribution to India’s clean energy goals. For many businesses, payback comes in four to six years, after which the power is almost free.
If you are planning a solar project, speak to Trefoil before you sign a contract. A small consultation at the start can save you from costly mistakes over the next 25 years.
