IEA’s World Energy Outlook systemically underestimates solar PV development
Since 1993, the World Energy Outlook (WEO) of the International Energy Agency (IEA) has been an authoritative report on energy statistics and guiding future energy supply and demand developments. An examination of these reports, however, indicates that even the most progressive of WEO scenarios has vastly underestimated the growth of renewable energy technologies, especially solar PV.
Optimizing residential PV-driven heat pumps with lithium-ion batteries reduces LCOE by 7%
Scientists in Spain have simulated the combination of power-to-heat-to-power storage systems with lithium-ion batteries to supply energy needs and heat pump production of an electrified dwelling. PV self-consumption was found to increase by up to 20% and levelized cost of energy decrease by 7%.
Segula presents compressed air storage system for residential applications
The system consists of a reversible compressor connected to a storage unit that can be installed indoors or outdoors. The compressor must be connected to the solar panels, with the whole system being controlled by an application that optimizes self-consumption.
FuturaSun releases 390 W silver solar panel
The Italian manufacturer said the new version of its silver module is ideal for grey roofs and buildings with modern architecture. It uses a 3.2 mm silver-coated glass and features a power conversion efficiency of 19.52%.
Amitime unveils residential propane heat pump
The Chinese manufacturer said its new heat pump system can continuously and stably provide hot water up to 75 C. At a temperature between 35 C and 55 C, the new product can reportedly achieve a seasonal coefficient of performance (SCOP) of 4.6 to 5.23, with COP values ranging from 3.86 to 5.63.
French solar-plus-storage product ‘could provide grid flexibility of six nuclear reactors’
Octopus Energy Services has responded to the government’s decision to slash the payments made to solar home owners for their excess electricity by launching its SolarPlus, home solar-plus-battery product.
Smoke and vanadium leak from Swiss home energy storage unit
Vanadium redox flow energy storage manufacturer Prolux Solutions said 50 l of vanadium electrolyte leaked from a residential unit in Arbon but no fire occurred.
GoodWe unveils hybrid inverters for large residential applications
GoodWe says its new EHB single-phase hybrid inverters suit larger residential energy storage applications with the series supporting 200% PV oversizing, allowing for systems up to 20 kW in size.
SMA releases 9.6 kW and 11.5 kW hybrid solar inverters
SMA America introduced two larger power classes to its Sunny Boy residential solar inverter line.
German home battery owners can save state millions with ‘a maximum of six clicks’
Berlin-based researchers behind the ‘Your Power Storage Can Do More!’ initiative want home battery owners to use intelligent charging to help the grid and state budget, and slow battery aging.
