A solar tracking system can make a major difference to the output from two solar photovoltaic (PV) projects located in the same area and having the same or similar PV modules and balance-of-plant systems. However, decisions regarding the use of a tracker can often be difficult for developers and may involve significant trade-offs between increased output, and the cost of installing a tracking system and maintaining it.

A growing number of renewables based off-grid solution providers in Bihar area working with villagers who have inadequate grid access and with commercial and industrial consumers facing poor grid reliability. Some of these consumers, who resorted to the use of expensive diesel generator (DG) sets, now report that renewable-based-off-grid solutions have reduced operational costs and environmental emissions.

In a bid to improve energy access and quality, Bihar, which is currently the fastest growing Indian state, has shifted its focus to renewable energy as an effective solution, especially for areas that do not have grid access or where the grid is unreliable.

A dye-sensitised solar cell (DSSC) is a thin film cell that uses thin layers of photosensitive organic dye deposits on a substrate to produce power from solar energy. In 2011, this technology took several important steps towards cost effective commercialisation, with major industrial players such as Tata Steel Europe (formerly the Corus Group) signing an agreement with Australia-based Dyesol, one of the original innovators of DSSC, for developing the world's largest dye-sensitised photovoltaic (PV) module, by printing a continuous series of dye-sensitised PV coatings on steel bars.

Increasing urbanisation and industrialisation has increased the amount of waste generated, leading to a greater need for scientific waste management. Due to the presence of high organic matter in industrial and, specifically, urban waste products, generating power from waste is a potential solution to the problem of both waste management and clean energy generation.
