What if the biggest opportunity in solar has been hiding in plain sight?

Josh Goldberg is no stranger to solar. He’s a multi-exit founder who helped shape residential solar finance—and now he’s back to tackle the “messy middle” of commercial solar. After stepping away from the industry, Josh returned with a mission: to unlock the underfinanced, overlooked world of small-to-mid-sized commercial solar.

In this episode, Josh shares how Sunstone Credit is solving a billion-dollar bottleneck—by giving installers and non-rated businesses the financing tools they’ve always needed. He opens up about what’s changed in the market (and what hasn’t), the whiteboard moment that sparked his latest venture, and why the time for this market is finally now.

Expect to learn:

🔹 Why the C&I market still hasn’t scaled like residential or utility

🔹 How Sunstone built bank-grade underwriting for an “unbanked” sector

🔹 The real reason pricing in commercial solar hasn’t improved in 15 years

🔹 What it took to convince banks to bet on a “brand new” asset class

If you’ve been wondering when large-scale commercial rooftops will finally go solar (or why it hasnt happened yet…), this one’s for you.
