Providing solar power for India’s first net zero energy building

SunPower, a Total group company in India, is actively providing world-class solar technology for the Indian market. SunPower is the second largest solar company in the world¹. With its solar photovoltaics, Sunpower helps to meet the challenge of diversifying the energy usage in India and provide cleaner and safer energy options for Indian customers.



Indira Paryawaran Bhavan, the first net zero energy building in India is a state-of-the-art landmark in terms of sustainability. It is constructed by Central Public Works Department (CPWD) to host the Ministry of Environment and Forests offices. It is uniquely powered with solar energy by adopting Green Building concepts, such as optimisation of energy and water, water recycling, conservation of naturally shaded areas and vegetation to reduce ambient temperature, maximise energy saving and minimise operations costs. 

Given the high energy generation requirements and limited rooftop area, SunPower high efficiency solar panels were chosen as an effective solution to fulfil the building’s energy needs. SunPower solar panels produce the most energy of all solar panels in the market², with 44% more power than conventional panels³. SunPower also provides a 25-year combined power and product warranty, warranting 9.1% more energy over 25 years compared to the traditional warranty. This first of its kind warranty guarantees that SunPower panels are made with durable materials designed to withstand harsh conditions.

As a part of CPWD’s mission and commitment to sustainable architecture, all newly built governmental properties in India are rated a minimum of three-star from Green Rating for Integrated Habitat Assessment (GRIHA). But Indira Paryawaran Bhavan with its ability to generate power on-site, is targeted to achieve a five-star rating from both GRIHA and Platinum Rating from Leadership in Energy and Environmental Design (LEED).
