A multi-level inverter for solar water pumps

Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly efficient at reducing switching losses thanks to a pulse width modulation technique.

94% households with solar home system say quality of life improved: GOGLA Research

Eleven per cent reported an increase in income levels by up to $66 per month on average. The impacts are seen even though a majority of solar home system customers also have grid access, highlighting that, as a complement to the grid, small scale solar still has a key role to play.

Rajasthan set to take the solar crown in 2020

Norwegian analyst Rystad Energy has predicted the stop on PV tenders in Karnataka will see Rajasthan become India’s leading solar state this year. The market research firm expects India to add only 10 GW new solar in 2020, however, and the same figure in 2021.

‘India will add 14 GW of solar this year’

The annual global outlook report for solar published by IHS Markit notes there was no real uptick in the amount of new capacity added last year, compared with the returns seen in 2018. That is likely to kill any hope India has of overtaking the U.S. as the world’s second biggest solar market in 2020.

Assam tenders 30 MW grid-connected, 940 KW off-grid solar

Ceiling tariff is fixed at Rs 3.13 per unit for the 30 MW grid-connected projects that are to be set up by state-run generators using domestically made equipment. The 940 KW of off-grid solar capacity is tendered under state budgetary support for year 2019-20.

Solar set for boom after a gloomy 2019

Solar installations in year 2020 are set to exceed 10 GW after a year hit by political uncertainties, module price increases associated with safeguard duty and a fewer number of awarded tenders. The outlook for battery energy storage installations for solar projects, however, is bleak as such combinations in India can cost 3-5 times more in 2020 than standalone renewable projects.

The long read: Shedding some light on Indonesia’s offgrid growth

Indonesia’s Central Bureau of Statistics reported in 2018 that 2,281 villages across the nation lacked access to electricity. As a vast archipelago with more than 17,000 islands, Indonesia faces serious challenges when it comes to electrification, as inter-island connection remains prohibitively expensive. Two experts in the field, Ahmad Agus Setiawan and Chayun Budiono, share their knowledge.

COP25: India calls for speedier expansion of International Solar Alliance

Launched in November 2015, the alliance aims to collectively address key challenges to the scaling up of solar energy in member countries that fall between Tropic of Cancer and Tropic of Capricorn. Out of 121 prospective member countries, over 83 have already joined it in a period of just four years.
