The solar energy industry moves fast. New panel efficiencies, battery chemistries, grid-scale projects, and policy shifts can change the economics of a residential or commercial installation within months. Trade shows and conferences exist to compress that learning curve — putting manufacturers, installers, developers, policymakers, and homeowners in the same room so the industry can make decisions in days rather than years. If you follow solar energy, whether you are a professional looking for the next product line or a homeowner trying to understand where the technology is headed, 2026 has an unusually strong lineup of events worth tracking.
This guide covers the major solar and renewable energy trade shows confirmed for 2026, starting with the nearest on the calendar and running through the flagship event of the year in Las Vegas.
Why Trade Shows Still Matter in the Solar Industry
Solar is a technology industry, but it is also a relationship industry. Installers need to trust the equipment they are putting on rooftops. Developers need to know which module manufacturers will still be around in twenty years to honor warranties. Homeowners benefit indirectly when the professionals they hire have vetted new products firsthand rather than relying solely on spec sheets and sales calls.
Trade shows accelerate all of that. They give manufacturers a concentrated audience, give buyers a way to compare competing products side by side, and give the industry a moment each year to take stock of where things stand. They are also where standards get discussed, where policy priorities get shaped, and where the next generation of installers and engineers gets introduced to the broader community. In 2026, that community is larger and more technically sophisticated than it has ever been.
Florida Solar and Storage Summit — May 7-8, 2026 | Orlando, FL
The Florida Solar and Storage Summit, organized by the Florida Solar Energy Industries Association (FlaSEIA), is the Southeast’s most focused annual gathering for solar and storage professionals. The 2026 edition takes place May 7 and 8 at the Orange County Convention Center in Orlando, which puts it within reach of both Florida-based installers and regional professionals from neighboring states.
The format blends conference sessions with an exhibit hall and hands-on technical training. That combination makes it relevant across experience levels — from a newly licensed installer looking to build competence with battery storage integration to a veteran contractor trying to understand what the next wave of utility rate structures means for their customer proposals.
Florida is one of the most consequential solar markets in the country. It has the sunshine, the roof stock, and a large population of homeowners facing some of the highest electricity rates in the Southeast. It also has a volatile regulatory environment — net metering rules, interconnection standards, and insurance requirements have all shifted significantly in recent years. The FlaSEIA Summit is where Florida solar professionals process those changes together and plan their responses. Registration is open, and early rates are available through the FlaSEIA website.
SNEC PV and Energy Storage — June 3-5, 2026 | Shanghai, China
SNEC is not a domestic event, but it is impossible to discuss the global solar industry without acknowledging it. The 19th SNEC PV and Energy Storage exhibition takes place June 3 through 5, 2026, at the National Exhibition and Convention Center in Shanghai. It is consistently one of the largest solar trade shows in the world, drawing manufacturers, component suppliers, and system integrators from across Asia, Europe, and the Americas.
For American homeowners and installers, the relevance is indirect but real. SNEC is where module manufacturers announce new efficiency milestones, where the pricing dynamics of polysilicon and wafers play out publicly, and where the technology roadmap for the next three to five years gets sketched out in exhibition booth presentations. The products that show up on American rooftops in 2027 and 2028 are often previewed at SNEC in 2025 and 2026. Following coverage of the event provides useful context for understanding why certain products are available, what they cost, and how they compare to alternatives.
IESNA Midwest — June 15-17, 2026 | Rosemont, IL
Intersolar and Energy Storage North America Midwest, now operating under the IESNA brand following the acquisition and rebranding of the former Midwest Solar Expo, holds its 2026 edition June 15 through 17 at the Donald E. Stephens Convention Center in Rosemont, Illinois — a suburb of Chicago that sits directly adjacent to O’Hare International Airport.
The Midwest market occupies a distinct position in the American solar landscape. States like Illinois, Michigan, Ohio, and Minnesota are working through their own renewable portfolio standards, utility commission proceedings, and incentive structures at different speeds. Grid interconnection for both residential and commercial-scale solar looks different in a PJM market than it does in California or Florida. IESNA Midwest is designed to address those regional specifics rather than assuming the California or Texas experience translates directly.
The 2026 event is the first held under the IESNA name in the Midwest, which means it carries some additional significance for the regional solar community as it establishes its identity and scope. It is expected to cover solar installation, energy storage systems, grid modernization, and the intersection of distributed energy resources with utility operations. Registration is open through the IESNA website.
The Energy Expo — August 12-13, 2026 | Fort Lauderdale, FL
The Energy Expo reaches its eighth edition in 2026, scheduled for August 12 and 13 at the Broward County Convention Center in Greater Fort Lauderdale. It bills itself as a focused B2B event for renewable energy, clean technology, and electrification professionals, with solar as a central component alongside battery storage, EV infrastructure, and related clean energy sectors.
Two days in late summer in South Florida is a demanding ask, but The Energy Expo has built a following among professionals who want a more intimate setting than the massive national conferences provide. Smaller events tend to favor genuine buyer-seller conversations over the overwhelming sensory volume of convention centers with thousands of exhibitors. For installers sourcing new product relationships or evaluating equipment suppliers for the first time, that dynamic can be more productive.
The Fort Lauderdale location also positions the event well for reaching both the residential and commercial solar markets of South Florida, one of the densest concentrations of solar-eligible properties in the country.
ASES SOLAR 2026 — October 19-21, 2026 | Austin, TX
The American Solar Energy Society’s annual national conference returns in 2026 as SOLAR 2026, taking place October 19 through 21 at the Palmer Events Center in Austin, Texas. The conference is held in partnership with the Texas Solar Energy Society during that organization’s 50th anniversary year, which adds a commemorative dimension to what is already one of the more technically rigorous solar conferences on the American calendar.
ASES conferences tend to attract a different audience than trade-focused events like RE+. The mix leans toward researchers, academics, policy professionals, and engineers engaged in long-horizon questions about solar technology and grid integration. Sessions tend to go deeper on technical topics — building-integrated photovoltaics, solar thermal systems, community solar models, and the social science of clean energy adoption — rather than focusing primarily on commercial product showcases.
Texas is an interesting host for this particular conference. The state has become a major solar market by virtue of its size, its deregulated electricity market, and the vulnerability its grid demonstrated during the 2021 winter storm. Austin itself has been a center of energy policy debate, with Austin Energy serving as one of the country’s more forward-looking municipal utilities. The conference theme, Solar for All, points toward equity and access dimensions that are increasingly central to how the solar industry thinks about its growth trajectory.
RE+ 2026 — November 16-19, 2026 | Las Vegas, NV
RE+ is the largest clean energy conference and trade show in North America, and the 2026 edition represents a significant milestone: the event moves to the Las Vegas Convention Center, where it will remain through at least 2028. The dates are November 16 through 19, 2026.
RE+ evolved from Solar Power International, the long-running annual conference organized by the Solar Energy Industries Association. In recent years it has expanded to encompass the full spectrum of clean energy — solar, battery storage, wind, hydrogen, electric vehicle infrastructure, microgrids, and more — while maintaining solar as its center of gravity. The 2026 event is expected to draw tens of thousands of attendees and hundreds of exhibitors from across the global clean energy supply chain.
For homeowners and residential solar customers, RE+ functions primarily as a background event — a window into where the industry is heading rather than a consumer-facing exhibition. But the decisions made and the products announced at RE+ flow downstream quickly. New battery chemistries shown in November often reach installation quotes by the following spring. Inverter platforms, monitoring systems, and grid-forming technologies that debut at the conference establish the baseline for what installers will be recommending to customers over the next twelve to eighteen months.
For anyone seriously engaged with residential energy independence — whether that means a rooftop solar system, a home battery backup, or a more complete off-grid or grid-hybrid setup — RE+ 2026 is worth following through industry media coverage even if the Las Vegas conference floor itself is not on your travel calendar.
Themes to Watch Across the 2026 Conference Season
Several themes are likely to run through the 2026 conference season regardless of venue or format.
Battery storage has moved from an add-on conversation to a central one. Three years ago, a residential installer might spend most of a trade show conversation explaining why a homeowner would want storage at all. Today the question is more often which chemistry, which warranty structure, and which utility rate environment makes the economics work. Expect storage integration to be a major thread across every event on this list.
Interconnection timelines remain a serious bottleneck. The gap between a homeowner signing a solar contract and getting permission to operate from their utility has lengthened in many parts of the country, driven by aging grid infrastructure and the sheer volume of new applications. Industry organizations are pressing for standardized processes and grid modernization investment. Trade shows are where that pressure gets organized and amplified.
The policy environment continues to create uncertainty around incentive structures. Federal incentive programs for residential solar and storage have been subject to ongoing legislative debate, and state-level net metering rules have been in flux in markets ranging from California to Florida to Nevada. Installers and homeowners alike benefit from following how the industry is processing and responding to those uncertainties, and trade show sessions are often where the most current analysis surfaces.
Module efficiency and cost continue their long trajectory of improvement. The difference between a standard residential panel available today and one likely to be on the market by late 2026 or early 2027 may not be dramatic on a single specification, but incremental gains across efficiency, durability, and manufacturing cost compound into meaningful differences in system pricing and payback periods. What gets announced at SNEC in June tends to reach American distribution channels within twelve to twenty-four months.
Planning Ahead
If you are a homeowner evaluating a solar installation in 2026, you do not need to attend any of these events to make a good decision. But staying loosely aware of the conference calendar is worth something. The period immediately following a major trade show — particularly RE+ in November — is often when installers have the most current information about new products, updated warranties, and revised pricing. Timing a purchasing conversation to coincide with that cycle can mean access to better information and, occasionally, better offers.
If you work in the solar industry in any capacity, the 2026 event calendar offers options across every region and budget. The Florida Solar and Storage Summit in May and IESNA Midwest in June both offer focused regional programming within weeks of each other. The Energy Expo in August provides a smaller-scale alternative for B2B relationship building. ASES SOLAR in October covers the research and policy dimensions that broader trade shows sometimes underserve. And RE+ in November ties the year together with the industry’s most comprehensive showcase.
Solar energy is, at its core, a long-term investment — in technology, in policy frameworks, and in the infrastructure of energy independence. The trade shows and conferences of 2026 are where the professionals shaping that future gather to compare notes. Following what happens at these events, even from a distance, keeps you connected to the direction things are heading.
