Acquiring more accurate measurements with ventilation and heating
Dew, frost, and soiling on the optical dome of a radiometer all have a significant negative impact as obstructions can lead to bad readings. Ventilation and heating are two ways to deal with this problem.
Novel assessment of PV-powered air conditioning
A research team in Turkey sought to assess how solar power may help reduce emissions and improve performance in air conditioning systems. Their analysis showed that using a heater in the AC system improves the coefficient of performance and mitigates negative environmental effects.
French start-up launches solar engine
The invention converts the energy produced by PV cells directly into mechanical motion without the need for batteries or power electronics. Its developers claim the robustness of the solar motor can drive water pumps and ventilation turbines for more than 20 years without the need for maintenance.
