rooftop solar

Battery storage manufacturer RedEarth has partnered with a major Australian housing developer to offer new-home buyers solar and solar/battery systems tailored to their needs from the get go – and with the opportunity to sell excess energy at optimized prices where the grid needs it most.

Rooftops will have to supply a third of the 524 GW of solar generation capacity needed by 2045 to reach a zero-carbon economy by mid century, according to an academic paper. The researchers also suggested green hydrogen should not play a central role in the nation’s energy transition.

The virtual battery records the surplus solar power injected into the grid on sunny days and returns it at night or in winter. If the production of the PV plant is not sufficient to cover all the electricity needs, MyLight Systems provides the household with green energy supplied by Swiss energy company Axpo.

The Solcan scheme had a budget of €20 million. Most of the assigned PV capacity will be located in the islands of Gran Canaria and Fuerteventura.

German manufacturer Autarq is selling its solar tiles at a price ranging from €25 to €30 per piece. It claims a PV system built with these products can cover around 70% of household needs.

The new net metering provisions came into force three years after the legislative process was launched. Power surplus will be sold to the grid at a rate of up to RUB2/kWh ($0.026).

The German photovoltaic manufacturer was once a trademark for German quality. After two bankruptcies, it is again active in Europe, primarily in the commercial and industrial rooftop segment. It sticks to the same philosophy: to offer superior solar solutions.

AGL has revealed plans to acquire Epho and Solgen Energy Group, which will make it Australia’s largest climate polluter and its largest commercial solar provider.

Lithium-ion batteries can not only improve self-consumption in commercial PV systems but are also able to efficiently perform peak shaving and price arbitrage, according to an international research group which has proposed a new strategy to calculate the best system configuration in terms of costs and revenue. The scientists specified, however, that the novel strategy may become effective only if storage system prices will drop under $250/kWh.

Of the 4.5 GW of small-scale solar capacity added in the United States in 2020, California accounted for 31%. New Jersey, New York, and Massachusetts are leaders for small-scale solar capacity despite having less favorable solar resources.
