Cost and prices

More than $200 million in equipment will be sold as Tesla plans to ramp up and expand operations at a Buffalo manufacturing facility.

PPA prices have been rising steadily since the end of last year and, according to solar developers, interconnection delays, permitting challenges, and supply chain constraints are likely to keep them high.

Solar prices have now dipped below the cost of wind in contract prices in many regions, analysis shows.

German scientists have assessed demand for resources such as glass and silver until 2100 and have found that current tech learning rates could be sufficient to avoid supply concerns.

The annual report found that residential system sizes continued to grow even as installed prices declined at a slower pace. Battery attachment rates are growing, but remained below 10% in 2020.

Also on the rise: JinkoSolar’s “very challenging” Q2, Silfab secures an investment, and megawatt-scale solar e-truck charging rolls into California.

When does increased energy production outweigh increased cost? Clean Energy Associates looks to answer one of its most-asked questions in a new case study.

Residential solar installation price declines have accelerated over the past year. However, energy storage pricing has gone up, with Enphase taking an increasingly larger share of the market.

The design uses metal brackets as mounting structures, conventional solar panels, and a grooved glass plate placed between the solar panels. System costs would be around $847/kW.

The maintenance cost of an electric vehicle is estimated to be significantly lower than internal combustion engines, and studies show home solar furthers the cost savings and boosts carbon emission reductions.
