Novel way to calculate levelized cost of hydrogen generated by offgrid PV
French energy giant Engie has developed a transfer function method based on a model used to assess PV plant variability. Its researchers claim that the new approach does not overestimate the levelized cost of hydrogen of an alkaline electrolyzer powered by offgrid solar.
Flowable silicone sealant to repair damaged solar module backsheets
The special sealant is based on a product developed by U.S.-based Dow Corning for solar panel frame sealing. Its creators claim the new solution is able to make damaged panels recover high insulation resistance and operate normally.
Residential lithium-ion battery from Belgium
The battery is available in three versions, with storage capacities of 3 kWh, 5 kWh and 7 kWh with all devices featuring a nominal voltage of 51.2 V and a maximum charging voltage of 56.8 V.
Off-shore PV project with LCOE of €0.15/kWh off the Belgian coast
Oceans of Energy is planning to deploy a 3 MW off-shore floating PV array in the North Sea.
Lithium-ion vs lead-acid batteries
An international research team has conducted a techno-economical comparison between lithium-ion and lead-acid batteries for stationary energy storage and has found the former has a lower LCOE and net present cost. Through their analysis, which was performed assuming the use of the batteries in connection with a 10 kW, grid-tied PV system, the scientists concluded that lithium-ion batteries are the most viable solution.
‘Polysilicon shortage will continue through 2021’
The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises.
Belgium’s Flanders region allocates 33 MW of PV in first renewables auction
The procurement exercise’s final prices for the PV source ranged from €0.0321 to €0.15 per kWh. The next auction will be held in September.
Testing field for PV noise barriers
Two testing facilities for photovoltaic noise barriers are being built by a Belgian consortium. Their creators want to assess different PV technologies, reduce costs and plan large scale projects in Belgium, where land and policy constraints make the construction of ground-mounted PV plants almost impossible.
ESMC criticises lack of solar manufacturing in Euro recovery plans
The trade body has highlighted a lack of explicit PV industry support in EU member states which already host domestic manufacturers, such as Germany, France, Austria, Belgium and Lithuania, and says the focus on green hydrogen could exacerbate the solar trade deficit with Asia.
Thermodynamic model to build more-stable perovskite solar cells
Dutch scientists claim to have developed a theory that explains the mechanisms behind halide segregation, which is the main factor affecting thermal stability in perovskite solar cells. They affirmed that the theory may provide technical solutions to build more stable perovskite PV devices.
