In today’s era, global warming is playing a major role in raising the average temperature of Earth’s surface due to rising levels of greenhouse gases. It has led to severe climatic changes worldwide, including rise in sea level, depletion of ozone layer and has had many negative effects on the ecosystem. In an attempt to alleviate these negative effects, the scientific community is focusing its efforts towards harnessing renewable energy resources and development of environment friendly energy efficient systems. However, constraints like the initial cost and specific operating conditions for adapting these innovative technologies are of major obstacle in their practical implementation.

In the scenario of a developing country like India, using solar power as a sustainable source of renewable energy is highly feasible due to its abundant availability. The present work describes three innovative products which would contribute to the Indian critical and ever increasing energy demands keeping in mind adverse environmental effects. The products described are selectively diverse and not compulsively constrained to a specific application since they are most common for domestic use in India. The working principle, return on investment analysis and methodology of product design are discussed in depth.
