Solar DC Cooking System, a step towards green &amp pollution free India

Here comes the sun: space-based solar power is on the horizon

CSIR-CMERI on 23rd September, 2021, Taking a small step in realising the dream of a ‘Pollution-Free India’, the CSIR-CMERI has developed a Solar DC Cooking System. In the distinguished presence of Swami Somatmanandaji Maharaj, Ramakrishna Mission Ashrama, Asansol, and Tapas Banerjee, Chairman, Asansol Durgapur Development Authority, Government of West Bengal, Prof. Harish Hirani, Director, CSIR-CMERI, handed over the newly developed Solar DC Cooking System to the Asansol Braille Academy of West Bengal. The Solar DC Cooking Technology developed by the CSIRCMERI has been transferred to two companies: Asansol Solar & LED House, and Meeco Solar & Infrastructure Associates, Durgapur.

How will it help to mitigate the Pollution?
The Solar DC Cooking System is a solar energy-based cooking system that includes a solar PV panel, charge controller, battery bank, and cooking oven. The technology offers a clean cooking environment, invertor-free direct operation, fast and uniform heating, and the ability to reduce 1 tonne of CO2 (Carbon Dioxide) per year /household. While speaking at the Press Conference, Prof. Harish Hirani, Director, CSIR-CMERI, expressed his gratitude for being able to hand over the indigenously designed Solar DC Cooking System to the Asansol Braille Academy, which has been doing an outstanding job in servicing Specially-Abled Children. The Solar DC Cooking System developed by the CSIRCMERI is a small step towards realizing that ideal of a pollution-free India.

How will it be beneficial for the citizens?
In comparison to conventional solar-based cooking systems, which lose efficiency due to ACDC conversion, the CSIR-CMERI designed Solar DC Cooking System has a 20-25 % higher efficiency and is more cost effective. The Micro-Industries could benefit from the basic technology design because it enables easeof-manufacturing and gives a significant economic opportunity. There is a chance that job prospects will improve as the popularity of technology grows.

Even if the use of LPG releases carbon dioxide, this system will significantly reduce carbon dioxide emissions. When the technology is out in the market, it would cost between Rs 65,000 and Rs 70,000. If government subsidies are offered, the price of the product will be significantly reduced, similar to other Solar Energy-based items. Widespread use of the
CSIR-CMERI-developed Solar DC Cooking System could help India meet its aim of 200 GW of solar energy, as envisioned by the Prime Minister Narendra Modi, as well as saving 290 million tonnes of CO2( Carbon Dioxide) emissions.

Why Solar Cooking?
Household air pollution from cooking fires in the home is a leading cause of respiratory disease, which kills many precious lives each year. Harnessing free solar energy for cooking will make drinking water safe, improve health, build resilient families, break the cycle of poverty, empower women and children and boost local economies as solar cookers do not produce any smoke.

Is Solar Power AC or DC?
Solar photovoltaic technology works on DC power. Solar panels generate direct current when the sun shines on panels, causing electrons to move and create current, thus, the current is direct as all of the electrons flow in the same direction.
