Two Japanese firms are teaming up to develop a major solar power facility combined with battery storage on the northernmost of the country’s main islands.
SB Energy, the renewables division of telecoms firm Softbank is working with Mitsubishi UFJ Leasing on a 102.3MW solar PV project combined with 27MWh of lithium-ion battery storage.
A new UK study has claimed there is currently “no economic benefit” from integrating electrical energy storage with solar PV systems in homes— and battery degradation could mean “significant” losses for homeowners.
According to the study by researchers at the universities of Warwick, Birmingham and the Centre of Excellence for Low Carbon and Fuel Cell Technologies, rooftop PV systems integrated with lithium-ion battery storage “are a promising route for the decarbonisation of the UK’s power sector”.
Astonfield and Solesa have teamed up to deliver power solutions, including PV-diesel hybrid systems, to India and East Africa.
The customised hybrid systems integrate solar PV with existing diesel generators to offset costs of diesel fuel for commercial and industrial power systems, claimed the two companies, marketed under the name of Astonfield Solesa Solar in India and Eastern Africa. The companies aim to deliver power solutions, ranging from industrial rooftop solar systems to ground-mounted solar and off-grid systems. The partnership intends to reduce power outages and combat rising energy costs.
A 100kW solar hybrid system will be installed in Tamil Nadu, India for Indo Shell Cast. Further contracts for systems between 100kW to 10MW are secured and first installations on industrial rooftops in Eastern Africa have started, stated Astonfield Solesa Solar.
A Navigant Research forecast predicts that the Indian market growth for diesel gensets between 15kW and 6MW will reach 82GW globally per year by 2018.
The German government’s scheme to offer subsidy payments to households who purchase a combined energy storage with PV system has got off to a weak start. Of the €25M available to householders, only €3.3M has been claimed. A further €25M is due to be available next year under the same scheme.
The government incentive scheme is intended to encourage the uptake of energy storage systems by offering non-repayable loans that cover up to 30% of the cost of a system.
Although the market is expected to blossom as part of the energiewende, the slow up take suggests householders are reluctant to install the systems.
In a recent report, Lux Research said the coupling of PV with energy storage will be beneficial to the storage companies, but have less impact upon the solar market. However, solar companies that choose to develop products that combine the two could earn a portion of the anticipated US$2.8 billion market in the next five years.
