The last 10 years have seen India emerge as a solar superpower, setting an example from which many emerging countries in Africa and Southeast Asia are eager to learn.

Dutch researchers have come up with a system they claim has a maximum estimation error of less than 10% and which reduces the computational requirements for calculating the output of PV systems in complex environments. The approach is based on the correlation between a skyline’s profile and annual irradiation.

Bifacial solar panel performance has become such a hot topic there are now at least four competing field test sites ramping up in the United States, each matching a different set of trackers and panels. DNV GL, Soltec, NREL and Sandia are all involved, and initial results are expected this year, once a year’s data has been collected.

According to a U.S. research team, new nanomaterials relying on dyes based on diketopyrrolopyrrole and rylene can generate a singlet fission reaction that extends the life of harvestable electronic charges.

Chinese PV manufacturer Hanergy Thin Film Power Group today announced it has achieved 24.23% cell efficiency using its silicon heterojunction technology. The efficiency has been confirmed by Japan’s Electrical Safety & Environment Technology Laboratories.

The irrigation department of the state of Uttarakhand has invited bids for setting up of 40.84 MW solar PV project at Haripura (27.34 MW) and Tumariya (13.50 MW) dams in district Udham Singh Nagar. The projects are to be built under build-own-operate-transfer model. The deadline for bid submission is February 15. Technical bids will be opened on February 18, while the date for opening of financial bids will intimated in due course.

The nation saw 1.3 GW of renewable energy secured for business through private PPAs in 2018, almost twice as much as the volume recorded in Australia, but the picture could change next year if China follows through with its renewable portfolio standard commitment.

Solar-wind and wind-only projects will be set up in centralized renewable energy parks along the lines of successful solar installations to keep power evacuation simple, under the terms of the state’s new land policy.

Setting up of the microgrid with battery energy storage is part of an extended R&D collaboration between ABB and the Indian Institute of Technology, Roorkee to create platforms for research on smart city technology deployment.

High solar irradiance and few cloudy days are ideal for solar. Fine dust and extreme heat is not – particularly when it comes to power electronics. As the distributed generation market segment emerges across hot climates, extreme conditions are a challenge inverter suppliers are grappling with.
