Distributed Storage

An international research team has designed a residential solar-plus-storage system based on gravity. The system was built with a solar power generator, a bulk booster charge controller, an inverter, a solenoid device, a deep cycle battery, a pulley block, a geared motor, a microcontroller, and wire ropes. Its creators said the system is ideal for regions with high solar radiation. They found that, due to its high electrical requirements, the system needs to rely on high-power solar modules with an output of over 500 W.

According to a new study from LUT University, domestic water heating costs may be reduced by combining rooftop PV with geothermal heat pumps. Scientists developed a control method to minimise these costs by taking advantage of cheap spot market electricity and maximised PV power generation, as well as considering heat demand, PV generation forecasts, and heat pump efficiency.

The smallest of the storage units has a capacity of 4.8 kWh and an output of 1.5 kW. It can be expanded to eight battery modules in steps of 2.4 kWh and has a maximum of 57.6 kWh, and 6 kW, of power.

The Institute for Energy Economics and Financial analysis (IEEFA) has published a report in which it points to seven key lessons energy planners the world over can take from South Australia’s extraordinary renewable energy integration. However, even South Australia, IEEFA’s model, still requires thoughtful planning and policy for the path forward.

The Housing SA Tesla VPP is being expanded to include a trial of 20 homes unsuitable for solar installation. The SA Government is offering free Tesla batteries to such homes to show how participation in the VPP with a battery alone can still deliver significant savings.

That’s the Commonwealth Bank of Australia we’re talking about, not the Commonwealth Government … but someone has to lead the way. Sustainability-savvy CBA is placing an investment bet on innovative energy retailer, Amber.

In a huge data-crunching project designed to inform rooftop solar-export policy and regulations, UNSW technical and social researchers delve into the costs and effectiveness of inverter standards.

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.

The deflagration-prevention system combines automatically controlled door locks with a smart controller which manages signals from fire safety inputs such as smoke, heat, or gas detectors. It is applicable from 50 kW to multi-megawatt cabinets.

In 2020, Anson Zhang, the CEO of Australia’s largest solar distributor, One Stop Warehouse, launched Discover Energy – entering the electricity retail space. The decision, Zhang told pv magazine Australia, confused many. Why would a company dominating solar supplies pivot to retailing. The simple answer: data.
