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.

Estonian companies working on a green hydrogen value chain in 5 to 10 years

Estonia relies heavily on oil shale, which accounts for 4% of the country’s GDP. The Baltic state is working to increase green hydrogen production, but PV is projected to maintain a marginal role despite the recent growth. We spoke about it with Estonian energy company Alexela and cleantech start-up PowerUP Energy Technologies.

Eurostat figures confirm rise of renewables during Covid-hit 2020

While solar, wind and hydro generated 80 TWh more electricity last year than in 2019, coal and oil use fell in every EU member state, and Greek energy emissions fell almost 19%.

Monograin layer solar cell with 6.4% efficiency

The lightweight and flexible cell was built by Estonian researchers with microcrystalline powders. The device is claimed to be the most efficient solar cell fabricated with a semiconductor compound known as Cu2CdGe(SxSe1−x)4.

Ten-year renewal of Estonia’s renewables support program

New €450 million incentive regime needed to be approved under EU state aid rules.

PV-powered hand sanitizer wins Covid-19 hackathon

An ESA-backed hackathon raised the idea of turning end-of-life PV modules into hand sanitizers. The team that won the hackathon is now working to rapidly roll out the solution at scale to contain the Covid-19 spread.

All-in-one device integrating a microinverter and optimizer

The so-called Optiverter is an all-in-one residential solution developed by startup Ubik Solutions and researchers from Estonia’s TalTech Power Electronics Research Group. The developers claim that the new solution can provide 30% more power than traditional microinverters under partially shaded conditions.

Estonian renewables auction attracts 17 bidders

The winners in the Baltic nation’s first clean energy auction will be announced by June 20. With the exercise rated according to the expected output of the facilities allocated, the government has committed to procure 5 GW worth of facilities, from a total 16.3 GW offered by bidders.

New kesterite solar cell with 8.7% efficiency

Estonian researchers have developed a new monograin powder technology made of microcrystals, which can form parallel connected miniature solar cells in a large module. By replacing copper with silver in the absorber material, the researchers were able to increase the efficiency of the cells by more than 2%.
