Morning Brief: DuPont Publishes 2020 Global PV Reliability Report, when will renewables pass coal?
Also in the brief: remembering the life of S. David Freeman, farmers in Rhode Island receiving solar grants, JA Solar’s upcoming webinar on the future of PV and more.
Overbuilding solar at up to 4 times peak load yields a least-cost all-renewables grid
The global energy firm Wartsila found a least-cost renewables mix for the U.S. that involves overbuilding renewable capacity, but requires no seasonal storage, and needs only four to ten days of multi-day storage capacity. The analysis modeled meeting current uses of electricity, based on projected technology costs for 2030.
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?
Morning Brief: NYC replaces fossil plants with storage and renewables, solar boom stalls in Texas
Also in the brief: a look at how pv systems relate to bird mortality, Sunverge has been chosen to manage a Maryland virtual power plant, a solar powered water filtration system and more.
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.
Solar inverters vs. cyberattacks
A U.S. research group is developing inverters and cybersecurity standards to protect solar installations from cyberattacks. The researchers said that inverters can shut down if they are hacked, or contribute to grid instability and result in the overcharging of batteries, while potentially creating problems that we still don’t know how to address.

Also in the brief: SEIA disappointed by USTR’s decision to remove Section 201 tariff exclusions for bifacial solar modules, plus VC investment in energy and grid startups.
Six-junction III–V solar cell with 47.1% efficiency
A U.S. research group has developed a new solar cell, based on six active photoactive layers, to capture light from a specific part of the solar spectrum. The scientists claim that they could potentially reach a 50% efficiency rate with the new cell.
