If you’ve been paying attention to the solar and battery storage world, you’ve probably heard the buzz around CLEANPOWER 2026. It’s the biggest clean energy event in the country, and this year it’s landing in Houston from June 1–4. I’ve been in the electrical and solar installation game long enough to know which trade shows are worth your time — and which ones are just corporate handshaking. Here’s what actually matters for homeowners.
What Is CLEANPOWER 2026 and Why Should You Care?
CLEANPOWER is the annual conference and exhibition put on by the American Clean Power Association (ACP). It brings together everyone in the clean energy supply chain — solar manufacturers, battery companies, inverter makers, wind developers, and the financing people who make projects happen.
We’re talking 500+ exhibiting companies, 8,000–9,000 attendees, and 200+ speakers spread across the George R. Brown Convention Center in downtown Houston. Last year, clean energy made up over 90% of all new power added to the American grid. That’s not a typo. The industry is booming, and CLEANPOWER is where you see what’s coming next.
Now, this is primarily an industry event. Most attendees are developers, manufacturers, and investors. But here’s why it matters to you as a homeowner: the products announced at CLEANPOWER this June are the panels and batteries that’ll be on your roof and in your garage 6–12 months from now. Knowing what’s coming helps you make smarter buying decisions.
What to Expect: Product Launches and Announcements
Based on what exhibitors have already confirmed and the trends I’m tracking, here’s what to watch for at CLEANPOWER 2026:
Home Battery Storage Is the Star
Battery storage installations jumped 41% year-over-year in 2025. In 2026, batteries will deliver 28% of all new utility-scale capacity. That investment is trickling down hard into the residential market. Here’s what’s on my radar:
- Tesla Powerwall 3 — The integrated 11.5 kW inverter with 13.5 kWh of storage in a single unit continues to set the benchmark. Watch for any software or capacity updates announced at the show.
- LG Prime+ — LG squeezed 16 kWh into the same footprint as their old 12.8 kWh model using higher-density cells. If you’re tight on wall space, this one’s worth watching.
- CNTE Stackable Battery — A modular residential battery that works with GoodWe, Victron, and Sofar inverters. Modular means you start small and add capacity later without ripping anything out.
- Nuvation Energy G5 BMS — They’ve confirmed live demos of their G5 High-Voltage Battery Management System and nController Energy Management System. This is the kind of tech that makes whole-home battery systems smarter and safer.
The big picture: SK Battery America and Samsung SDI are both beginning U.S.-based ESS battery production in 2026. More domestic manufacturing means shorter lead times and (eventually) lower prices for homeowners. Even Ford is pivoting from EV manufacturing into stationary storage — that’s how big this market is getting.
Solar Panel Tech
The panel efficiency race keeps heating up. Expect to see next-generation panels pushing past 23% efficiency for residential modules, along with better low-light performance and improved aesthetics (all-black panels are the norm now, not the premium). I’ll be watching for any tandem cell or perovskite announcements that could reshape the market in 2027–2028.
AI-Powered Energy Management
This is the sleeper trend. With data centers and AI workloads driving a massive surge in electricity demand, the smart energy management space is exploding. For homeowners, that means better apps, smarter load shifting, and systems that actually learn your usage patterns instead of just following a timer.
The Numbers: Dates, Location, and Ticket Prices
Let’s get practical:
- Dates: June 1–4, 2026
- Location: George R. Brown Convention Center, 1001 Avenida De Las Americas, Houston, TX 77010
- Advance Registration (through April 30): $1,089 (ACP members) / $1,449 (non-members)
- Regular/Onsite (May 1 – June 4): $1,219 (members) / $1,629 (non-members)
- One-Day Expo Pass: Use promo code CP26ONE at checkout
- Students: Discounted rate with proof of enrollment
- Official Website: cleanpower.org/expo
I’ll be honest — at $1,400+ for a non-member ticket, this isn’t exactly a casual weekend outing. If you’re a homeowner who’s about to drop $30,000–$50,000 on a solar-plus-storage system, walking the expo floor and talking directly to manufacturers could save you money and headaches. But for most people? Follow the coverage online and put that $1,400 toward your actual system.
If you’re shopping for solar quotes, skip the expo ticket and use EnergySage instead — it’s free, and you’ll get competing quotes from pre-vetted installers in your area.
Tips If You Actually Decide to Go
If you’re making the trip to Houston, here’s how to get the most out of it:
- Register before April 30 to lock in advance pricing and save $180.
- Use the exhibitor directory at cp26.mapyourshow.com to plan your route. With 500+ booths, you need a game plan or you’ll spend the whole day wandering.
- Wear comfortable shoes. The George R. Brown Convention Center is massive. You’ll walk 5+ miles on concrete floors.
- Bring a portable charger. You’ll be scanning QR codes, taking photos of spec sheets, and your phone will be dead by noon. A solid portable phone charger is non-negotiable.
- Carry a small notebook or use a notes app. You’ll talk to 20+ vendors, and by the end of the day they all blur together. Write down the model numbers and rep names while they’re fresh.
- Hit the expo floor stages. There are 6 show floor stages with 25-minute presentations on emerging tech. These are more digestible than the full conference sessions and usually cover the newest stuff.
- Houston in June is brutal. Pack light, breathable clothing and a refillable water bottle. It’ll be 90°F+ with Houston humidity. The convention center is air-conditioned, but you’ll be outside getting between venues and hotels.
- Grab a good backpack. You’ll collect brochures, swag, and product samples. A lightweight daypack keeps your hands free and saves your shoulders.
The Bottom Line for Homeowners
CLEANPOWER 2026 is the event where the next generation of residential solar panels, home batteries, and energy management systems gets unveiled. The U.S. added a record 50 GW of clean power in 2025, and 2026 is projected to smash that with 86 GW of new capacity. That growth means more competition, better products, and — eventually — lower prices for homeowners.
Here’s what I’d actually recommend:
- If you’re an industry professional or installer: This is a must-attend. Full stop.
- If you’re a homeowner about to buy solar or batteries: Consider the one-day expo pass. Walking the floor and talking to manufacturers in person is valuable when you’re about to make a five-figure investment.
- If you’re a homeowner who’s just curious: Save your money. Follow SunBacked and other outlets for coverage. I’ll be posting takeaways from the show floor.
The clean energy market is moving fast. Whether you attend CLEANPOWER 2026 in person or follow along from home, the important thing is staying informed before you sign a contract. Get multiple quotes through EnergySage, do your homework on the products announced at the show, and don’t let any salesperson pressure you into yesterday’s technology.
