Mitsubishi unveils propane heat pump for residential applications
Mitsubishi Electric has developed an air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 5 kW and 8.5 kW of heat and domestic hot water to a temperature of up to 75 C.
Zendure introduces residential batteries for balcony solar modules
Zendure’s SolarFlow batteries have capacities of 960 Wh and can be stacked up to 3,849 Wh. The US manufacturer wants to begin selling the plug-and-play systems in April.
UK cathedral to install solar, storage system
York Minster, one of the largest cathedrals in Northern Europe, has secured approval to install 199 solar modules on its rooftop. The system will generate at least 75,000 kWh per year and will be paired with batteries.
New plug-and-play mobile PV system
The “Solar Box” mobile power plant is a container consisting of solar modules, a battery storage system, and a hydrogen storage system. According to Austria’s Alternative Energy Projects (AEP), the system starts at 94 kW and can be scaled up to more than 5 MW.
Optimizing off-grid PV systems for different design criteria
A new report by IEA PVPS Task 18 provides a blueprint guide on how to conduct feasibility studies for off-grid and edge-of-grid power systems. The optimal system size and specifications vary depending on the client’s priorities. The desired project outcomes can be identified using pure financial analysis (NPV, IRR) or additionally taking environmental performance into account.
