Solar stocks are being pulled in two directions in September 2026. Long-term demand remains compelling because solar can add generation capacity quickly, while rising electricity consumption, grid expansion and battery storage continue to support investment. At the same time, tariff risk, subsidy scrutiny and trade actions can change the economics of a project or manufacturing footprint with little warning. Reports that Washington is considering restrictions on foreign-made inverters have underscored how quickly policy signals can move the group, making company selection more important than simply owning broad solar exposure.
The industry is also becoming more segmented. Utility-scale module manufacturers compete on technology, capacity and supply-chain positioning; residential installers depend on customer acquisition, financing and storage attachment; inverter and balance-of-system suppliers provide the hardware needed to connect projects; and developers or equipment providers can benefit from contracted or recurring project activity. Vertically integrated businesses and companies connected to storage or grid infrastructure may have more ways to absorb pricing pressure than pure hardware vendors, although no segment is insulated from policy changes.
This countdown examines seven U.S.-listed solar energy stocks, moving from #7 to #1. The ranking begins with depth of exposure to the solar theme and then considers business fundamentals, including profitability, growth, valuation, earnings execution and analyst sentiment. The result is a cross-section of the sector rather than a single bet on modules, residential systems or utility-scale infrastructure.
Methodology brief. The screen covers U.S.-listed companies with market capitalizations above $500 million and meaningful operating exposure to solar energy. Stocks were ordered first by the depth and directness of their solar exposure, then by business fundamentals such as margins, returns, growth, valuation, earnings history and analyst consensus. The list is presented in countdown order, so the highest-ranked pick appears at #1. Composite quality grades and primary-source financial data provide additional context, but they do not eliminate policy, execution or market risk.
What they do. The company sells electrical balance-of-system solutions and components used by solar and battery-storage projects in the United States and internationally. Its portfolio includes big lead assemblies, homeruns, combiners, disconnects, transition solutions, wireless monitoring and battery energy storage products, with revenue also coming from OEM components and technical support services sold to EPC firms, utilities, developers and other project participants.
Why it fits. Shoals is a direct infrastructure play on solar deployment rather than a module manufacturer or residential installer. Its EBOS products are necessary for connecting and operating utility-scale solar projects, while its BESS offering gives the company an additional link to the storage buildout that is increasingly important for managing intermittent generation.
Numbers that matter. Revenue growth was 47.4% year over year, but earnings growth was negative 12.5%, showing that strong sales expansion has not translated into comparable earnings momentum. Gross margin was 32.1%, operating margin was 13.81% and net margin was 5.42%; revenue was $588.1 million and EBITDA was $100.6 million. The trailing P/E was 41.2368 compared with a forward P/E of 12.6904, while estimated next-year EPS was $0.5512 versus TTM EPS of $0.19.
Recent momentum. Shoals beat estimates in the latest reported quarter, posting EPS of $0.10 versus an estimate of $0.09, a 11.1% surprise; the prior quarter also produced a 16.7% beat. Its reported beat rate was 3/7, so the recent improvement has not been consistent across the full history. Analysts included 4 Buys, 7 Holds and 1 Sell, with an average target of $11.3158, supporting interest but not a unanimous view.
What they do. Array Technologies manufactures and sells solar tracking systems across the United States, Spain, Brazil, Australia and other international markets. Its products include single-axis and dual-row trackers, terrain-following systems, photovoltaic-powered controls and software-based monitoring products, giving the company a project-equipment revenue model centered on improving the positioning and operation of large solar arrays.
Why it fits. Solar tracking is a specialized utility-scale segment: the equipment is designed to help panels follow the sun and improve power production from a project site. That makes Array a highly direct solar exposure, but also leaves it tied to the pace of utility-scale development, project economics and capital spending by developers and EPC customers.
Numbers that matter. Revenue declined 5.6% year over year and earnings growth declined 73.2%. Gross margin was 26.8%, operating margin was 10.88% and net margin was negative 7.25%; TTM EPS was negative $0.96, although next-year EPS is estimated at $0.8906. The core valuation data show no trailing P/E because the company is unprofitable, while forward P/E was 5.0633, a low-looking multiple that must be weighed against the weak earnings base.
Recent momentum. The most recent reported quarter was a sharp beat: EPS of $0.22 compared with an estimate of $0.07, a 214.3% surprise. The preceding quarter also beat by 220.0%, but the full reported beat rate was 4/7, reflecting uneven execution. Analysts listed 3 Buys and 11 Holds with no reported Sell count, and the average target was $8.6023, indicating constructive interest alongside significant operating concerns.
What they do. Sunrun designs, sells, installs, owns and maintains residential solar systems in the United States. Its offering combines solar panels and racking with battery storage, while the company reaches homeowners through direct, digital, retail, field-marketing and partner channels and also serves commercial developers through multifamily and new-home projects.
Why it fits. Sunrun provides one of the clearest residential solar exposures in the group, with an integrated model that spans customer acquisition, installation, ownership and maintenance. Its battery-storage offering is particularly relevant as households and utilities look for ways to manage intermittent generation and improve the value of distributed solar systems.
Numbers that matter. Revenue grew 52.8% year over year, while reported earnings growth was negative 60.7%, illustrating the volatility of the earnings profile. Gross margin was 35.3%, operating margin was 4.0% and net margin was 11.59%; revenue was $3.476 billion and EBITDA was $840.6 million. The trailing P/E was 5.8027 and forward P/E was 8.0451, with TTM EPS of $1.47 and estimated next-year EPS of $1.0148.
Recent momentum. Sunrun beat estimates in 6 of the 7 reported quarters. The latest quarter delivered EPS of $0.42 versus an estimate of $0.08, a 425.0% surprise, after a prior-quarter EPS result of $0.62 compared with an estimate of negative $0.05. Analysts listed 5 Buys, 9 Holds and 1 Sell, with an average target of $15.9737, but the composite rating remained Neutral despite the strong recent beat record.

What they do. SolarEdge develops power optimizers, DC-to-AC inverters, storage systems, EV chargers and energy-management software for residential and commercial solar installations. Its cloud monitoring platform, installer applications, design tools and technical services extend the offering beyond hardware, with products sold through distributors, electrical wholesalers, installers and EPC firms.
Why it fits. Inverters and power optimizers are central balance-of-system components because they convert and manage the electricity produced by solar panels. SolarEdge also has direct exposure to the storage, EV charging and software layers of the energy transition, but that breadth does not remove its sensitivity to residential demand, channel inventories and policy treatment of inverter supply chains.
Numbers that matter. Revenue grew 19.6% year over year and reported earnings growth was 659.8%, but the comparison began from a depressed base. Gross margin was 21.3%, operating margin was negative 6.52% and net margin was negative 20.29%; EBITDA was negative $121.1 million and TTM EPS was negative $4.49. The core data show no trailing P/E because of losses, while forward P/E was 78.7402, a demanding multiple for a company still operating below break-even.
Recent momentum. The latest reported quarter missed estimates, with EPS of negative $0.26 versus negative $0.23 expected, a 13.0% shortfall; the prior quarter missed by 59.3%. SolarEdge's reported beat rate was 3/7. Analysts listed 21 Holds and 1 Sell with no reported Buy count, and the average target was $39.55, while the composite quality grade was Strong Sell.
Market cap: $4.6B · Quality grade: B · Analyst consensus: Hold (avg target $52.49)
What they do. Enphase designs and sells semiconductor-based microinverters that convert electricity at the individual solar-module level, along with networking and monitoring software. Its product range also includes IQ Batteries, gateways, energy routers, EV charging solutions, design and permitting services, appointment generation and Enphase Care services sold through distributors, installers, OEMs, partners and homeowners.
Why it fits. Enphase offers concentrated exposure to the inverter and residential energy-management portions of solar, while its batteries and EV charging products connect the company to storage and electrification. The microinverter architecture and software layer give Enphase a differentiated product position, although demand remains tied to the health of residential solar markets.
Numbers that matter. Revenue declined 19.6% year over year and earnings growth declined 3.5%. Even so, gross margin was 30.0%, operating margin was 17.98% and net margin was 10.09%; ROE was 13.0% and EBITDA was $191.8 million. The trailing P/E was 34.4158 and forward P/E was 13.0548, with TTM EPS of $1.01 and estimated next-year EPS of $2.2666.
Recent momentum. Enphase beat estimates in 5 of the 7 reported quarters, although the latest quarter was a 12.5% miss at EPS of $0.14 versus $0.16 expected. The prior quarter was a 4.4% beat, with EPS of $0.47 versus $0.45 expected. Analysts listed 5 Buys, 19 Holds and 1 Sell, producing a Hold consensus and an average target of $52.4926.
