Solar inverter fault detection techniques at a glance
New research has categorized all existing fault detection and localization strategies for grid-connected PV inverters. The overview also provides a classification of various component failure modes and their potential causes in a tabular form.
EU adopts directive allowing reduced VAT on several goods, including solar panels
The Directive No. 2022/542 was published in the Official Journal of the European Union on April 5. According to the new provisions, member states will be free to apply a VAT rate of 0% to 5%.
India may miss 2022 solar target of 100 GW by 27%
A new report by JMK Research and the Institute for Energy Economics and Financial Analysis (IEEFA) says India is likely to miss its 2022 solar target of 100 GW by about 27 GW, mainly due to the underwhelming growth of rooftop solar. While utility-scale solar is on track to achieve nearly 97% of the 60 GW installed capacity targeted by 2022, rooftop solar will be 25 GW short of the 40 GW mark.
Concentrating solar power system for building applications, usable with PV
Conceived by a German start-up, the system is claimed to achieve a 75% efficiency in converting direct radiation into heat. It may be either equipped with solar trackers or photovoltaic modules, which would both occupy the same space on the front and lateral sides of the installations.
Photovoltaics for electric cooling
According to new research from Sweden, solar PV might be cost-competitive in powering electric cooling for an investment cost ranging from $165/kW to $480/kW in hot-climate countries such as Brazil, Spain, India and China, among others. The study focused on the cooling demand for the residential sector, where most of it is expected to originate.
Bangladesh’s highest-opex rooftop PV plant goes online
Bangladesh has inaugurated its largest rooftop solar array under the opex model, at a location south of Dhaka.
Residential heat pump produces water up to 75 C
Scientists in Spain have developed a new heat pump that can produce 6.49 kWh of heat for each kilowatt-hour of power it consumes. The device could generate hot water at a temperature of up to 75 C.
Austria launches €240 million rebate scheme for rooftop PV
The Austrian government has more than quadrupled the budget for the 2022 edition of its rooftop solar rebate program.
Designs, control strategies for PV-integrated shading devices
Photovoltaic shades in buildings offer energy efficiency and electricity generation, but an international research group says their commercial viability will depend on the control strategies used to optimize performance.
Ikea invests €340 million in solar
Ikea’s holding company, INGKA Holding, will invest €340 million ($371 million) to acquire nine PV systems from Enerparc. In the future, Ikea said it will work with Svea Solar to sell residential PV systems.
