Residential PV

The Scottish government wants to deploy renewable-powered heat pumps on at least 1 million homes and 50,000 non-domestic buildings by the end of this decade. For this purpose, it has created an advisory group and is now seeking to gather all potential stakeholders.

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 minimize these costs by taking advantage of cheap spot market electricity and maximized PV power generation, as well as considering heat demand, PV generation forecasts, and heat pump efficiency.

The government of the archipelago is tendering the deployment of two big batteries, with capacities of 24 MW/24 MWh and 16 MW/16 MWh, respectively, to store renewable energy for 22 islands.

Homeowner associations and town councils can derail your solar project, but so can dust from nearby factories and bivalve mollusks falling from the sky.

French grid operator RTE has outlined six scenarios on how France’s energy system may achieve carbon neutrality by 2050. In the most optimistic one, solar is expected to reach a cumulative capacity of 208 GW.

Building renovations may result in up to 51% space heating demand savings, according to recent research from Germany. Its authors claim that, if buildings are retrofitted and thermal energy storage and individual hybrid heat pumps with back-up gas boilers are applied on a large scale, significant heat cost reduction may be achieved across the whole of Europe.

Poland-based Green Cell is offering two versions of its new inverter, with power outputs of 1 kW and 3 kW. The inverters feature an efficiency of 90% and are recommended for small buildings such as cottages or year-round homes.

Q Cells Australia says many residential solar customers are contemplating exiting the grid entirely as policymakers grapple with how to integrate small-scale renewables like rooftop solar PV and batteries into the electricity system.

Energy efficiency, electrification of heating and transport, and the provision of clean cooking facilities are all going in the wrong direction as the Covid crisis deprived millions in sub-Saharan Africa of electricity use, according to a report by the IEA, IRENA, WHO, World Bank and UN Statistics Division.

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.
