Why are millions of apartment rooftops still empty while single-family homes cash in on solar savings?Turns out it’s an accounting problem – a technicality known in industry jargon as the “split-incentive” and it’s keeping renters and property owners sidelined from benefiting from distributed generation on-site.In this episode, we sit down with Dover Janis, co-founder and CEO of Ivy Energy, to explore the split incentive that’s held multifamily solar back for years. Dover and his team are building the software backbone that makes solar pencil for both property owners and renters - and their traction is accelerating.You’ll hear how Dover went from boots-on-roof solar tradesman to leading a team solving one of the most persistent challenges in the clean energy transition. If you’ve ever wondered why multifamily solar adoption has been so sluggish—or how to unlock a massive untapped market—this is your blueprint.🔹 The “last mile” problem stopping solar on apartments🔹 How Ivy’s platform makes energy equity bankable for landlords🔹 The hidden policy battles shaping the multifamily solar market🔹 What it takes to scale hundreds of megawatts with just a few customersExpect bold insights, regulatory war stories, and a rare look at how Ivy Energy could transform real estate owners into a new class of clean energy providers.Check out OpenSolar OS 3.0 at: https://suncast.media/opensolarIf you want to connect with today's guest, you’ll find links to their contact info in the show notes on the blog at https://suncast.media/episodes/.Our Platinum Presenting Sponsor for SunCast is CPS America!You can learn more about all the sponsors who help make this show free for you at www.suncast.media/sponsors.Remember, you can always find resources, learn more about today’s guest and explore recommendations, book links, and more than 875 other founder stories and startup advice at www.suncast.media.Subscribe to Valence, our weekly LinkedIn Newsletter, and learn the elements of compelling storytelling: https://www.linkedin.com/newsletters/valence-content-that-connects-7145928995363049472/You can connect with me, Nico Johnson, on:Twitter - https://www.twitter.com/nicomeoLinkedIn - https://www.linkedin.com/in/nickalus

Landfill explosions, lithium-ion firestorms, and CIA briefings—today’s guest has seen it all - or so she thought!Kathleen McCaffery’s illustrious firefighting career includes crawling through rubble in Haiti, leading battalions as one of the first female fire chiefs in North America, and even rewriting Tesla’s global fire safety strategy. This episode takes us into uncharted territory as Tesla recruits a retired firefighter to address global concerns over battery [fire] safety.Most solar companies are woefully underprepared to interact with firefighting agencies, and that’s increasingly going to create friction and unnecessary limitations.  Kathleen spent her entire career breaking down barriers (when she wasn’t breaking down doors!) and has even been in the situation room of more than a few CIA operation briefs! To say she is battle-tested is putting it mildly. She answered the call to serve the country (CIA) and those in need (disaster relief), but could not have been prepared for the call she received post-retirement that pulled her back into active duty, this time taking her halfway ‘round the world to help solve battery fires in Australia! This is one of the most fun and wild conversations we’ve published all year.Expect to learn:🔹 The hidden dangers of damaged lithium-ion batteries (and why we don’t just bury them)🔹 Why the age-old truism “big fire, big water” doesn’t work for Batteries🔹 How Tesla created a new role just to fix their fire communication gap🔹 Why every developer needs to build relationships with local fire operators, not just permit officesFrom Pentagon rescue missions on 9/11 to training Tesla teams, Kathleen’s insights are not only fun and eye-opening—they’re critical for every solar professional adding batteries to their portfolio.Check out OpenSolar OS 3.0 at: https://suncast.media/opensolarIf you want to connect with today's guest, you’ll find links to their contact info in the show notes on the blog at https://suncast.media/episodes/.Our Platinum Presenting Sponsor for SunCast is CPS America!You can learn more about all the sponsors who help make this show free for you at www.suncast.media/sponsors.Remember, you can always find resources, learn more about today’s guest and explore recommendations, book links, and more than 875 other founder stories and startup advice at www.suncast.media.Subscribe to Valence, our weekly LinkedIn Newsletter, and learn the elements of compelling storytelling: https://www.linkedin.com/newsletters/valence-content-that-connects-7145928995363049472/You can connect with me, Nico Johnson, on:Twitter - https://www.twitter.com/nicomeoLinkedIn - https://www.linkedin.com/in/nickalus

More batter density = more value, right? Not so fast.In this episode, we challenge the hype around energy storage density—and reveal what really drives value for battery storage assets.At RE+ 2025, Nico Johnson got to connect with two powerhouse product leaders from Wärtsilä Energy Storage: Neha Sinha, Head of Hardware Portfolio, and Ruchira Shah, Lead for Software Product Management. Together, they’re crystal clear about how hardware and software integration impacts performance, revenue, and long-term viability in energy storage projects. And how that translates to strategic value for battery operators.If you think “more megawatt-hours per box” is the endgame, you might be oversizing your system—and leaving cash on the table. Neha and Ruchira explain why “usable energy,” not just nameplate capacity, is the real metric investors should care about. And why that’s not solely defined by  the MWH you can stuff inside a container.Expect to learn:🔹 Why density ≠ value (and when high-density enclosures actually hurt your ROI)🔹 How software helps unlock stranded energy and accurate bidding🔹 The surprising role of chillers in degradation—and how to optimize them🔹 How to navigate site constraints, noise ordinances, and permitting barriersIf you're bidding into markets or scaling storage assets, this episode is your wake-up call: performance, not just packaging, determines profits.Check out OpenSolar OS 3.0 at: https://suncast.media/opensolarIf you want to connect with today's guest, you’ll find links to their contact info in the show notes on the blog at https://suncast.media/episodes/.Our Platinum Presenting Sponsor for SunCast is CPS America!You can learn more about all the sponsors who help make this show free for you at www.suncast.media/sponsors.Remember, you can always find resources, learn more about today’s guest and explore recommendations, book links, and more than 875 other founder stories and startup advice at www.suncast.media.Subscribe to Valence, our weekly LinkedIn Newsletter, and learn the elements of compelling storytelling: https://www.linkedin.com/newsletters/valence-content-that-connects-7145928995363049472/You can connect with me, Nico Johnson, on:Twitter - https://www.twitter.com/nicomeoLinkedIn - https://www.linkedin.com/in/nickalus
