Clean Power Hour

For the first time, batteries and solar powered California around the clock, with batteries running as the number one morning electricity source at nearly 6,000 megawatts. Tim Montague and John Weaver break down this milestone and a packed week of clean energy news, from a Supreme Court ruling striking down global tariffs to a Republican push to reinstate the 30% solar ITC.

EPISODE HIGHLIGHTS

• California achieved 24/7 solar and battery power for the first time. Batteries discharged through the night and morning, charged on near-free midday solar, then discharged again in the evening. (PV Magazine)
• Republican House member Brian Fitzpatrick voted against the "One Big Bill" over the removal of solar and wind tax credits and now pushes to reinstate the ITC. (E&E News)
• The Supreme Court ruled Trump's global tariffs illegal. John clarifies this removes the 10-20% blanket tariffs on goods like copper, steel, and aluminum. Solar module tariffs, battery tariffs from China (40-60%), and Southeast Asian tariffs remain in place.
• Indonesia's solar imports surged from 6 megawatts to 2.5 gigawatts of modules in under two years. Petitioners in the AD/CVD investigation now cite "critical circumstances." Expect new tariff action targeting Indonesian modules. (Solar Power World)
• Hithium completed the world's first open-door fire safety test on a 6.25 MWh battery energy storage system. Even with doors open and safety systems disabled, adjacent battery units were undamaged. (ESS News)
• Tim reports the number of battery companies at Intersolar roughly doubled year over year, now outnumbering solar module companies.

With the ITC phase-out approaching, electricity prices climbing, and battery deployments accelerating, the stories covered here directly affect procurement decisions, financial modeling, and market strategy in 2026.

Most solar asset owners still manage performance data the same way they did 10 years ago. Dan Leary, founder of Denowatts, says that needs to change. In this episode, recorded live at RE+ Northeast in Boston, Tim Montague sits down with Leary and Doug Macmillan of Portside Systems to explore energy accounting, a method for identifying exactly where solar production losses occur and what owners and operators should do about them. Denowatts is collaborating with Sandia National Laboratories to build what Leary calls "GAAP for solar," a common standard for reporting and benchmarking solar asset performance. If you manage solar assets or invest in solar projects, this conversation explains how better data practices lead to more predictable returns.

EPISODE HIGHLIGHTS

• Dan Leary explains that most solar operators still manage data the way they did a decade ago, despite significant advances in monitoring and analysis tools. Denowatts built a smarter weather station (the Deno) and a real-time analytics platform to close that gap.
• Denowatts breaks down solar production losses into four categories: climate-related issues, modeling errors, external factors beyond anyone's control, and problems within the commercial boundary that owners and operators are able to fix. This framework gives asset managers clear direction on where to focus recovery efforts.
• Doug Macmillan explains Portside's role as the system integrator for the Denowatts platform on distributed generation sites. Portside handles design, equipment fabrication, delivery, and commissioning, working from their UL 508 panel shop.

This episode is for solar asset managers, project developers, EPCs, and clean energy investors who want more from their performance data. With Denowatts and Sandia Labs working toward a common reporting standard, the solar industry is moving closer to the kind of financial transparency that attracts long-term capital. If you own or operate solar assets, the time to modernize your data strategy is now.

The 30% investment tax credit is going away. The safe harbor window closes July 3, 2026. After that, commercial solar stands on its own. So what separates the companies that thrive from the ones that disappear?

Costa Nicolaou, founder and CEO of PanelClaw, joins Tim Montague at RE+ Northeast in Boston for a direct conversation about surviving and growing in the post-ITC market. This episode covers domestic manufacturing strategy, FEOC compliance, logistics innovation, and three specific moves every solar installer and EPC should make right now.

Episode Highlights

- The ITC was a runway, not a permanent subsidy. Costa frames the 30% credit as a 10-year opportunity to build manufacturing capacity, drive innovation, and prepare for an unsubsidized market. The companies that treated it as a margin cushion instead of a building tool are the ones at risk.

- PanelClaw doubled its US manufacturing capacity in 2022 and expanded again. The company operates a full just-in-time domestic production model. No inventory. Enough capacity to serve the entire US flat roof market from American facilities.

- PanelClaw is the only flat roof racking company with 100% FEOC compliance for the January 1 through July 3, 2026 window. Their products qualify for the complete domestic content stack: rail, structural fastener, and production.

- ClawLogic gives EPCs real-time visibility into every order. Line items, pallet sizes, pallet weights, ship dates, and a live truck tracker. Costa modeled it after Amazon's delivery tracking experience. The platform has been live for three years. No competitor in flat roof racking has replicated it. PanelClaw is now launching ClawLogic in Europe.

- Costa delivers three rules for solar installers preparing for the post-ITC market. First, resist the race to the bottom. Second, pursue extreme collaboration across the value chain. Third, ask every supplier about their innovation roadmap.

The safe harbor window is closing. FEOC compliance deadlines are active now. The decisions you make this year on partners, manufacturing, and operations will determine whether your company leads or exits by 2028.
