Distributed Storage

The new product combines the NEO 800TL-X Microinverter and the NOAH 2000 Battery. Up to four batteries can be stacked, for up to 8,192 Wh of storage capacity.

Energy storage is the new solar for an increasing number of Chinese PV manufacturers. However, China still requires enabling policies for storage to provide the end-market volumes needed to bolster the fortunes of manufacturers old and new.

The Chinese manufacturer said its new heat pump has a coefficient of performance of 4.2 at 7 C and a maximum heating capacity of 9.1 kW. It can reportedly achieve a topwater output temperature of 75 C.

The new products are intended for commercial applications and and multi-dwelling buidlings. They have a size of 20 kW to 30 kW and use R290 as the refrigerant.

The need for long-duration energy storage in a net-zero world is undeniable but with conventional battery prices tumbling, can anything dislodge the mainstream grip of lithium ion? S&P Global’s Susan Taylor provides an update on non-lithium storage technologies.

There may be a global solar boom but a drastic revision of California’s net metering program has ruptured the industry overnight and is affecting everyone from installers to financiers to makers of power electronics.

While lithium ion battery prices are falling again, interest in sodium ion (Na-ion) energy storage has not waned. With a global ramp-up of cell manufacturing capacity under way, it remains unclear whether this promising technology can tip the scales on supply and demand. Marija Maisch reports.

Researchers and investors say they see room for PV investments in Zanzibar, due to the energy needs of many luxury holiday resorts.

Researchers in Australia have compared the technical and financial performances of a hydrogen battery storage system and a lithium-ion battery when coupled with rooftop PV. They evaluated two commercially available systems – LAVO and Tesla Powerwall 2 – and found that the lithium-ion battery provides better financial profits, whereas the hydrogen battery offers more battery lifespan for long duration of energy storage.

Lower costs, better supply chains and steady demand are driving an energy storage boom in the United States, according to a new report from Wood Mackenzie.
