Germany may install 150,000 residential batteries this year
German market research company EUDP Research expects 85% of the new storage systems will be used in new PV systems and 15% in existing installations.
Optimization model to combine residential PV with hybrid hydrogen storage
German scientists have outlined a model to combine hydrogen storage with conventional battery storage in high-efficient energy buildings powered uniquely by photovoltaics. In the proposed configuration, the DC power of the PV system is connected directly to the hybrid hydrogen system, a lithium-ion battery, an electric water heater, and an inverter, which in turn would provide AC current to the household and a heat pump.
Australian solar executive highlights importance of software, data
Anson Zhang, the CEO of Australian solar distributor One Stop Warehouse, entered the retail electricity market in 2020 by launching Discover Energy. The move confused many people, but he said the decision was driven by an interest in data.
Solar 101: The basics of net metering for your solar project
The concept of net metering is important to understand, as it affects how long your solar project takes to pay for itself, and how your contractor will design your project. Here’s what you need to know.
Growing interest for PV arrays with eastern and western orientation in Germany
A report from Fraunhofer ISE reveals that the share of PV systems with southern orientation has decreased from 61% in 2000 to 42% in 2019. It also highlights that solar rooftop installations with a tilted angle lower than 20 degrees have increased from just 5% in 2000 to 24% in 2019.
Concrete battery for applications in buildings, rooftop PV
A prototype of a cement-based battery has been developed in Sweden for potential applications in buildings. Its creators claim it could become a solution to store electricity from rooftop PV and they do not exclude that it could also be used for the storage of large-scale renewables.
Maxeon launches frameless rooftop solar panels
Maxeon’s Air technology platform brings solar to previously inaccessible roof spaces.
Solarwatt unveils two bifacial glass-glass panels with half-cell design
The most powerful of the two products has a power output of up to 380 W and an efficiency of 20.4%. For both panels, the temperature coefficient is -0.37%. The German manufacturer said the modules are produced at its manufacturing facility in Dresden.
Solar 101: What’s my solar system going to cost?
Think of your solar system as a custom retrofit. That means the list of unique variables and components can be long, and hardware requirements may result in significant pricing differences.
Dutch farmers left with no connection for their PV arrays
Grid congestion issues are increasing in the Netherlands and several Dutch farmers claim to have remained without access to the grid despite having completed their rooftop arrays.
