The relationship of PV and metal roofs: Mounting system installation
In the final entry of the three-part whitepaper series, S-5! and the Metal Construction Association take a look at the critical technical factors for solar PV systems specific to mounting on metal roofs and illustrates how long-term performance of roof-mounted solar PV systems can only be achieved through careful planning, design, procurement, installation and quality control.
MCE approves 100MW solar-plus-storage project in California
Golden Fields Solar will be constructed with union labor using a Project Labor Agreement and will include pollinator-friendly habitats throughout the project site.
Connecticut Green Bank surpasses $2 billion in total investment
Since July 2011, the nation’s first Green Bank mobilized $288.4 million in public dollars to attract $1.85 billion in private investment, a leverage ratio of $7.40 for every $1.
CleanCapital acquires 65MW solar portfolio spanning 12 states
The acquisition improves CleanCapital’s position in the rapidly-consolidating market share of the top commercial solar asset owners.
Powin to supply 5.8GWh of batteries for projects in US and Taiwan
The US battery specialist has signed framework agreements with four developers to deliver systems for multiple projects.
“Interconnection studies could be completed in months,” say SEIA, AEE and ACP in comments to FERC
With standardization and automation, interconnection studies “could be completed in months instead of years,” the groups told federal energy regulators, backing up their claim with a detailed plan to achieve that goal.
Sunrise brief: Finance experts discuss growing opportunities for installing storage projects and what will make them more financeable
Also on the rise: Solar growth occurred despite more than a year of price increases. Interconnection delays and costs plague utility-scale developers. Affordable hydrogen-based system for seasonal energy storage could be achieved at a hydrogen price lower than $3. California PUC raises renewable energy target. Impending 3G shutdown may affect inverters: there’s an app for that.
Lessons learned from Texas storm Uri
Winter storm Uri that brought a deep freeze to Texas is also bringing insight into grid vulnerabilities, the need for more renewables, and the potential of solar-plus-storage.
Hydrogen under $3/kg may ensure affordable seasonal energy storage in the US
Researchers from the United States have investigated how fuel cells and electrolyzers may be able to operate under intermittent availability provided by both wind and solar and have found that an affordable hydrogen-based system for seasonal energy storage could be achieved at a hydrogen price lower than $3, produced from inexpensive renewable electricity at $0.02/kWh.
Interconnection delays and costs are the biggest barrier for utility-scale renewables, say developers
LevelTen and Advanced Energy Economy point to delays in the PJM grid region, in particular. Construction of the 300GW of renewables and storage projects in PJM’s interconnection queue would support 1.7 million jobs, says AEE.
