The Climate Group has reported that just 33 members of its global EP100 initiative avoided carbon dioxide emission by one billion metric tonnes purely through energy efficiency measures. Of this, 360 million metric tonnes—comparable to taking 77 million cars off the road for a year—was avoided in the last year alone.
The prime minister again emphasized the need for India to develop a domestic solar manufacturing industry and also urged officials to get on with plans to make Ladakh carbon-neutral.
The OneBox, from Indian manufacturer Vision Mechatronics, consists of a lithium battery, hybrid inverter and solar charge controller to give a hassle-free solution for electricity back-up during power outages. Solar rooftop owners are offered a grid feed feature to maximize net metering income from any excess power generated.
The disparity between central and state government renewables policies must be resolved and renegotiating signed PPAs is an absolute no-no, according to the solar business’ bosses.
The invention converts energy produced by PV cells directly into mechanical motion without batteries or power electronics. Its developers claim the solar motor can drive irrigation water pumps and ventilation turbines for more than 20 years without maintenance.
This 1.2 MWp project would generate more than 80% of power requirements of the Akal University and 13 Akal Academies. It has been built at a total cost of Rs 5.2 crore, out of which the Ministry of New and Renewable Energy has provided a total subsidy of around Rs 1.7 crore.
The municipal council of Karimnagar has mandated rooftop solar on new buildings of a certain size as part of the Ministry of New & Renewable Energy’s Smart City Mission, which requires 10% of municipal energy to be generated from solar.
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.
