Opinion & Analysis


Carbon neutrality and solar’s role in ASEAN nations

The Paris Agreement has been signed by all ASEAN nations and almost all members have declared a carbon emissions reduction target. The diversity in ASEAN’s readiness for energy transition is reflected in the wide-ranging nationally determined contribution targets set for reducing greenhouse gases. An immediate quick win for the renewable energy transition is the harnessing of solar power from an abundance of resources in the region.

N-type solar development

This year, PV cell manufacturers will face the challenge of transformation. Apart from adjusting the ratio of production for different-sized cells, some manufacturers are turning to next-generation opportunities, shifting investment from p-PERC to n-type technology. PV InfoLink Analyst Amy Fang discusses the issues facing n-type cell development this year.

PV policy developments in the Baltic states

Estonia, Latvia and Lithuania have seen uneven development in PV installations to date, and the three Baltic states are still highly dependent on imports from Russia. Estonia needs to replace aging energy infrastructure, and so far it has led the region in PV deployments. Latvia, meanwhile, has a high level of hydro in its energy mix, and less incentive to build PV. IHS Markit analyst Susanne von Aichberger examines the latest policy developments in the Baltic states.

IHSM clean energy insights: High module prices and shipping costs jeopardize 2021 installation outlook

In the first installment of a new monthly blog by IHS Markit, Edurne Zoco, executive director for clean energy technology, writes that high prices and increased freight costs are putting solar PV procurement teams under extreme pressure, particularly those teams with connection deadlines this year that were anticipating a more favorable pricing and logistic environment in the second half of 2021.

Turning Nepal’s solar game around

Until 2016, Nepal suffered from chronic power shortages. At that time, just 65% of the country’s population had access to electricity. Assessing the situation, the International Renewable Energy Agency (IRENA) estimated that the country has the potential for 2.1 GW of installed PV capacity. Although the Nepal Electricity Authority (NEA) has officially been able to buy solar power under long-term PPAs since July 2014, the majority of projects granted these contracts have been large-scale hydropower plants. Following slow activity, plans are finally afoot, however, to boost the country’s solar footprint.

Australia’s energy storage installed base to grow more than five times by 2030

In its latest report, IHS Markit predicts that energy storage installations in Australia will grow from 500 MW to more than 12.8 GW by 2030. Today, Australia makes up less than 3% of total global installations for battery energy storage and is the seventh largest market globally. By 2030, it is forecast to comprise 7% of global installations and become the third largest market. This growth will be largely driven by three distinct market segments: residential, standalone front-of-the-meter, and collocated with utility-scale renewables.
