Types of Solar EPC Projects in India
In 2025, India’s solar energy sector continues to expand, encompassing various types of Engineering, Procurement, and Construction (EPC) projects. The primary categories include:
Utility-Scale Solar Projects
These large-scale installations, often exceeding 1 megawatt (MW), are designed to supply power directly to the grid. They are typically developed in expansive areas with high solar irradiance. The Indian government’s initiative for the development of solar parks and ultra-mega solar power projects aims to facilitate the rapid deployment of such utility-scale installations.
Rooftop Solar Installation
Rooftop solar projects involve installing photovoltaic panels on the roofs of residential, commercial, or industrial buildings. They enable consumers to generate their own electricity, reducing dependence on the grid and lowering energy costs. The growing adoption of rooftop solar installations is contributing to India’s increasing solar energy capacity.
Floating Solar Farms
To address land constraints, floating solar farms are being developed on water bodies such as reservoirs and lakes. These installations reduce water evaporation and minimize ecological disruption. States like Kerala and Maharashtra are exploring floating solar projects to utilize underused water surfaces for energy generation.
Hybrid Solar Systems
Hybrid systems combine solar power with other energy sources, such as wind or diesel generators, to provide a more stable and reliable energy supply. These systems are particularly beneficial in areas with variable weather conditions, ensuring consistent power generation.
Off-Grid Solar Solutions
Off-grid projects are designed for areas without reliable access to the central power grid. They provide localized energy solutions, often incorporating battery storage to ensure a continuous power supply. The Prime Minister’s Farmer Energy Security and Upliftment Campaign (PM-KUSUM) supports the construction of 500 kW to 2 MW solar power plants and the installation of 1.4 million off-grid solar agricultural pumps, aiming to add significant photovoltaic capacity.
Government Policies & Incentives for Solar EPC Companies in India
