KPN for Solar Industries

Indian solar market is gaining worldwide attraction due to favourable weather and policy incentives. India€™s theoretical solar power reception capability is about 5000 Trillion KWh per year based on the land area and about 300 clear sunny days. The daily average solar energy incident over India varies from 4 to 7 kWh/m2 with about 1500–2000 sunshine hours per year (depending upon location). India currently has 1040 MW of solar connected to the grid.  As per the Jawaharlal Nehru National Solar Mission (JNNSM), this capacity is expected to touch 10,000 MW by 2017 and 20,000 MW by 2022. Off-grid solar installed capacity is expected to reach 2000 MW by 2022.

In addition to JNNSM, various states have their own solar policies which are driving solar development.

Need for Energy Storage combined with Solar Power in India

The fundamental drawback of any renewable energy is its intermittent nature. Solar power is available only for 6-8 hours during the day. Also, conditions like cloud covers, dust accumulation and other weather related events can create significant fluctuations in solar power.  Reliance on solar, can thus affect grid stability and hence can put limits on the development of solar energy. 

Integrating appropriate energy storage technologies with solar systems in India can make solar power despatchable, reduce stress on the grid and optimize overall system resources.  For example, with a grid-tied PV system combined with storage can allow for the sale of excess energy to the grid.  In addition, energy storage can play an important role in optimally sizing the solar PV systems for off-grid usage.  Storage combined with solar can also improve the return on investment in solar by allowing the customer to utilize the solar energy most cost effectively. Energy storage systems can also provide the reactive power support required to ensure power quality.

For Solar thermal storage, various applications like thermal mass systems, molten salts and pumped storage hydroelectricity can be used. Thermal mass systems can lower the customers peak demand, reduce overall cooling and heating requirements, and shift Time of Day (ToD) to off peak hours. Thermal mass systems are an ideal alternative to space heating. Thermal energy storage systems can help optimize the size of the Concentrated Solar Power (CSP) systems and help meet the needs for the end users during evening or early morning hours through efficient storage.

Why join IESA - KPN?

There is tremendous interest in the development of solar projects in India amongst both domestic and international companies. The Ministry of New and Renewable Energy (MNRE) as well as the Indian Renewable Energy Development Authority (IREDA) position storage as the next key aspect which will aid and provide a credible roadmap to the renewable energy spectrum in India. IESA is in active dialogue with leading companies and central and state regulatory and statutory bodies involved in formulating the policy framework for continuous growth of solar in India. IESA brings the latest advancements in energy storage and micro grid technologies from around the world to India through its members. IESA-KPN membership provides you an opportunity to access the cutting edge developments that will impact solar development and will help position your solar business effectively for opportunities in the growing Indian energy market.
