In a funny twist of fate, solar’s success has made it old news. It’s the fastest-growing source of electricity in the world and one of the cheapest. But it’s far from the hot topic it was a decade ago when utility-scale photovoltaics were still an emerging technology. Now that it’s a more mature tool in the climate fight, we take it for granted.

And yet there’s so much more we need to do. To reach net zero by 2050, we likely need to quadruple global solar capacity by 2030, according to projections by BloombergNEF (BNEF). But labor shortages, high material costs and interconnection bottlenecks stand in the way. 

So how do we get there?

In this episode Shayle talks to Jenny Chase, who managed BloombergNEF’s solar insights team for 17 years before leaving the role this month. Every year she tweets a thread of 50 not-always-popular opinions on solar, covering the state of the industry and the challenges it needs to solve. For this episode, Shayle picked the opinions he found most interesting and unpacked them with Jenny. 

They cover Jenny’s opinions on:

• The biggest bottlenecks holding back solar deployment, like labor shortages, high polysilicon prices and grid interconnection backlogs
• Why we don’t need new technology breakthroughs in solar
•  Perovskite and building-integrated photovoltaics 
•  How residential solar and battery salespeople are making up their savings projections
• How the U.S. Inflation Reduction Act could spur an unsustainable boom in solar and hydrogen equipment manufacturing
• Why leading forecasts could be underestimating solar deployment
