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.

Smart sticker for smart solar modules

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.

Adhesive mounting system for any kind of solar modules

The system, developed by Spanish specialist Alusín Solar, is being tested by Endesa in a 9.8 MW project for self-consumption. The mounting structure is made with aluminum bars that, instead of being fixed to the roof with screws, are attached through a double-sided adhesive.
