A new strategy to mitigate voltage spikes in small solar systems
The approach combines virtual impedance and a modified pulse-width modulation strategy to suppress fault currents in grid-connected PV systems.
The best way to predict the I-V profile of PV panels
A study has considered the best mathematical models for predicting solar module performance under varying conditions.
Lead-free soldering in modules: It can be done!
pv magazine’s UP sustainability campaign has investigated the use of lead in PV panels and found, with soldered cell interconnections in particular, viable alternatives are scarce. However, German headquartered manufacturer Opes Solutions has launched a small module for the off-grid market featuring lead-free solder, developed at the request of a customer. We caught up with Opes CEO Robert Händel for a closer look at the module and the challenges and benefits of going lead-free.
Panasonic claims 16.09% efficiency for lightweight perovskite solar module
The device has an area of 802cm² and thickness of 2mm. The manufacturer claims it improved module performance through an inkjet coating method and a reduction in weight by using thin glass substrates.
Mysterious new chlorophyll with potential PV applications
Japanese researchers are studying the ‘Chl f’ substance which features a pigment in photosynthesis which can absorb far-red light from the lower end of the spectrum.
Crop yield rises with solar-powered irrigation
PV systems have helped farmers in the Philippines become less dependent on rain. Projects in Camarines Sur have shown pumping water with solar is not only cheap but can also raise rice yield.
Pilot agrovoltaic project with mobile PV modules launched in France
The solar facility, near Lyon, will be developed by Engie unit Compagnie Nationale du Rhône. Tests will be carried out for three years at a project intended to demonstrate the benefits of combining solar with agriculture.
Longi claims 22.38% efficiency world record for PERC mono panel
The Chinese manufacturer said the result was confirmed by Germany’s TÜV Rheinland. The achievement beats the company’s previous record of 21.65%, set last month.
All-inorganic perovskite solar cell hits 16.1% efficiency
Researchers from the City University of Hong Kong have developed an all-inorganic perovskite cell with an electron-pair donor which offers a pair of non-bonding electrons. The cell was developed by applying that ‘Lewis base’ small molecule to passivate the inorganic perovskite film.
Jinko claims two more efficiency records for bifacial panels
The Chinese manufacturer has achieved conversion efficiencies of 21.82% and 22.49% for its p-type PERC and n-type HOT bifacial panels, respectively. The results were confirmed by Germany’s TÜV Rheinland.
