How to combine photovoltaics with rainwater harvesting

Scientists have developed a system that harvests rainwater running off PV panels for household use or hydrogen production. Their analysis showed that, in the southern Sahel, the system can meet both the energy and water requirements for electrolysis, with surplus rainwater covering up to 50% of a household’s daily water demand.

What’s cooking in PV?

Scientists have conducted an analysis of 20 years of academic publications about PV-powered electric cooking and have found interest in the field peaked in 2021-2022 in both developing and developed countries. They have also outlined some potential future developments.

Field manual for off-grid residential PV in remote communities

A research team has constructed a technical field audit among users of solar systems in remote communities in Ghana and has identified some recurring technical issues. Based on the collected data, the scientists have also developed a practical field manual.

New research analyzes performance ratios of bifacial PV

A comparison between monofacial and bifacial PV systems in Ghana showed how changes in system parameters can affect the bifacial gains. The researchers found that changing the albedo of a land-based system can increase the bifacial gain from 5.25% to 14.5%.
