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

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.
Solar-plus-storage for aquaculture aeration
Recent research from Thailand has shown that solar-plus-storage on floating platforms could be the cheapest option to power energy-intensive aeration systems in aquaculture projects. The battery accounts for around 54% of the capital costs, which is why system sizing would be key for economic viability.
