The vice-president for marketing and product strategy at one of only two inverter suppliers to Tesla says it has promised customers that it can “get the battery within six months”.

Elon Musk’s Tesla has done the rest of the storage industry a big favour by putting a price point on lithium-ion batteries, according to the CEO of Sonnenbatterie’s North American operations.

The International Renewable Energy Agency has published a technology roadmap aimed at accelerating the deployment of electrical storage for renewable energy.

While debates over renewable energy targets continue to rage at the political level in Australia, Panasonic has signed a deal with three utility companies to pair its energy storage systems with rooftop solar.

Lessons learned from solar could help develop financing solutions for energy storage that could be “key” to unlocking the potential of the technology, strongly benefiting PV in the process, Jigar Shah has said.

SolarEdge, one of only two companies at present to produce Tesla Powerwall-compatible inverters, will launch its expanded range of residential and commercial solutions at Intersolar Europe next month.

One analyst has predicted that 12,500 residential PV storage systems could be installed in Germany in 2015, more than the total number of systems installed with support from a government scheme in its first two years.

Tesla’s grand entrance to the stationary storage market has been (largely) welcomed but question marks remain over the company’s business model. Andy Colthorpe gauges the latest reaction and explores the options facing Elon Musk.

Tesla reported losses of around US$0.36 per share in its quarterly earnings announcement yesterday, despite a flurry of activity around its stationary storage launch last week – yet the company still outperformed the expectations of the investment community.

Ecotricity, a UK-based supplier of renewable and clean energy, will trial a home energy storage box later this year.
