Brazil introduces new rules for distributed generation, net metering

The Brazilian authorities have introduced new rules to ensure that PV systems below 5 MW in size will still be eligible for net metering tariffs until 2045. A grid fee for prosumers will go into effect from 2023, but the economic profitability of rooftop PV and small solar parks is expected to remain high.


South Korea installed 4.4 GW of PV capacity in 2021

South Korea’s cumulative installed PV capacity hit 22 GW at the end of 2021, according to provisional figures from the Korea Energy Agency.


New Yorkers fund 4 GW of solar for less than a cup of coffee per month

The New York Governor’s Office has submitted its financial proposal for 4 GW of distributed solar capacity by the year 2030, at an expected cost of $0.00082/kW.

The weekend read: BIPV no refuge

Deployment in the building integrated PV segment is accelerating, and so too are the number of solar products available to architects and developers. And while BIPV had long been the segment in which an array of thin-film technologies could shine, they are now in increasingly stiff competition with crystalline silicon rivals.


Vattenfall launches high-temperature heat pump solution to replace gas boilers

Developed in partnership with Dutch heating specialist Feenstra, the all-electric heat pump solution will initially be available in the Netherlands. The system’s buffer works as a heat battery that is used to provide heat to radiators and generate hot tap water.


Brazil tops 13GW of installed PV capacity

The country installed around 3GW of new PV systems in the fourth quarter of 2021 alone. Around 8.4GW of the current PV capacity is represented by solar installations not exceeding 5MW in size, and operating under net metering.


PV-assisted heat pump module facade for power supply, heating, cooling, and ventilation

Designed by scientists in Germany, the module facade has to be integrated with a building’s technical equipment. The rooms behind the facade can be supplied with solar power and at the same time heated, cooled and ventilated.


Novel design for shingled solar modules

Researchers in Singapore have created a flexible framework for designing hotspot-resistant shingled modules. Their work is claimed to be perfectly compatible with existing manufacturing techniques.


India added 935MW of private-contract backed solar in first nine months of 2021

That meant the nation reached a cumulative 4.8GW of “open-access” solar generation capacity by the end of September. At that point, there were also more than 1.1GW of open access projects in the development pipeline, according to analyst Mercom India Solar.
