The Chennai Metro Rail Limited seeks to procure 90 million units/annum of solar or solar-wind hybrid power, or 72 million units/annum of wind power through tariff based competitive bidding. Tariff ceiling is fixed at Rs 3.50/KWh for 25 years. Bidding closes on February 13.

The proposed model is said to perform better at energy prediction than software tools such as PVWatts, PVSyst or RetScreen. The approach was validated on two 5 MW PV plants in the same district of the Indian state of Rajasthan.

Chinese researchers have developed a pure EVA film, which they claim can enhance the conversion efficiency of conventional crystalline solar cells by around 0.50%. The film is able to convert UV light into strong visible light.

US scientists are proposing a new approach to calculating the optimum angular-tilt of PV panels for a planar surface at a particular site. In their view, the new technique may unlock innovative yield optimization methods for the installation of PV systems.

With this, the West African nation becomes the first International Solar Alliance (ISA) member to avail services of NTPC. Presently, there are six programmes of the ISA to develop solar capacities in member countries, which include agricultural pumps, mini grids, rooftop solar, large-scale grid connected projects, etc.

Applications are invited for setting up cumulative grid-connected capacity of 10 MW for Uttar Haryana Bijli Vitran Nigam and 15 MW for Dakshin Haryana Bijli Vitran Nigam. The solar power generated will be purchased by Discoms at a pre-fixed levelized tariff of Rs 3.11/KWh.

Materials that can recover energy wasted in the form of heat and convert that into electricity can pave the way for devices that can be coupled with new renewable technologies such as solar-thermoelectric and Lithium batteries.

European research group Solliance says its perovskite modules have passed three key industry standard reliability tests: Light soaking, damp heat and thermal cycling. The group said it is the first time perovskite modules of that size have achieved such results and represents a milestone in the technology’s move toward commercialization.

The Gujarat-based power generator, which aspires to cross 100 MW capacity milestone in 2019-20, has touched 40.75 MW as an independent power producer and close to 4 MW as captive power producer.

Under the order worth around Rs 1730 crore, the power transmission and distribution player’s latest supervisory control and data acquisition and advanced distribution management solution technology will help deliver 24×7 reliable power to the people of the twin cities of Jammu and Kashmir.
