Low-cost, portable sun-tracker for offgrid solar

Mauritian researchers have developed a solar tracker prototype that increases current by around 37%. The device uses a simplified and mechanical tracking system.

Germany’s first photovoltaic cycling path goes online

Badenova has installed 912 glass-glass PV modules along a cycling path in the city of Freiburg, Germany, as part of a new pilot project.

Study shows n-type bifacial TOPCon cells more prone to degradation than p-type

Dutch scientists have reported higher degradation risk for n-type TOPCon cells with EVA encapsulant due to potential moisture degradation. Front-side metallization makes n-type cells more vulnerable than p-type cells, according to damp heat tests.

PV-powered robotic lawn mower from New Zealand

Researchers from Massey University in New Zealand have developed a robotic lawn mower with three 50 W solar panels and a 20 Ah lithium-iron-phosphate (LiFePO4) battery. Two of the PV panels can be retracted and stacked inside the robot. They slide out when it needs to recharge its batteries.

Mobile solar system for agricultural farms

India’s Vivasvan Solar has designed a foldable solar structure mounted on a trolley. The system employs mechanisms to prevent damage to the panels during transit and is especially useful for agricultural farms.

Dust removal for solar panels via electrostatic cleaning

A Jordanian research team has designed a cleaning technique for solar modules that uses static electricity to remove dust from panel surfaces. The system features an electrostatic ionizer that reduces attraction between dust particles and their accumulation on modules, improving their energy yield.

PV-powered underground heat exchanger for buildings

Researchers in India have combined PV generation with heat produced by an earth-to-air heat exchanger to provide buildings with space heating and cooling. They say the proposed system could result in an annual energy gain of 8116.7 kWh.

Jakson Green to develop green hydrogen refuelling station in New Delhi

The green hydrogen production, compression, storage, and distribution facility will be powered by an in-situ hybrid renewable power and storage plant.

How to successfully implement robotics and automation in solar PV plants

Solar projects in India face many challenges due to the complex terrain of the solar plants, making the proper implementation of robotics and automation quite a challenge.

US company develops robotic solution to address installer shortage

Sarcos has designed a robotic PV construction solution that delivers, detects, lifts, and places PV modules in large-scale solar plants. It has recently field tested and validated the prototype solution in a pilot project funded by the US Department of Energy.
