The challenges and tricks of adding battery storage to existing solar projects
Alencon Systems teamed up with Duke Energy to look at some of the challenges faced by a utility when adding a battery storage system to an existing solar installation. DC-coupled or AC-coupled? Grounding scheme?

500 W-plus panel race intensifies with JA Solar’s new module and Risen’s first shipment
Chinese manufacturer JA Solar has announced a new 525 W+ panel and said the product will be available from the second half. Domestic rival Risen has shipped the first batch of its high-powered modules and intends to stick to pre-Covid-19 plans to ramp up production.
Lithium-ion storage is here to stay with no ‘post Li-ion’ era in sight
A German-Israeli research group has gathered to discuss which storage technologies may outperform lithium-ion batteries in the future. They concluded that there is no such a thing as a “post Li‐ion” era in sight. They recommended a “side‐by‐side” approach for multiple technologies in different applications, as well as the hybridization of technologies.
Distributed storage could save Texas $344 million per year by deferring transmission and distribution costs
Adding enough distributed storage to reduce peak demand by 20% could defer up to one-fifth of the transmission and distribution expenditures in Texas for about 10 years, a study found. Other states may find the study’s analytical insights to be useful.
The financial and social struggles of getting large solar projects financed
The pre-life of the Spotsylvania solar energy project has been riddled with financial and societal difficulties. As much as these issues have made a quagmire of development, it also provides a case study on the logistics of getting such a large project built.
Vivint beats on revenue — but losses widen in Q1 as residential solar hunkers down
Vivint beat estimates with $91.2 million in revenue in Q1, though, like with most other third-party solar companies, that was outweighed by $51.9 million in losses from operations. Installation figures fell during the quarter and are only expected to fall further, as Covid-19 runs its course on residential solar.
