The ACCE Clean Energy index sits at NAV 1074.66. Here's how GEV, FSLR, NEE, SEDG, ENPH, PWR, and the full portfolio break down in mid-2026.
The ACCE Clean Energy index carries a NAV of 1074.66 as of June 15, 2026. Ten names. Three distinct business models. One theme that has fractured into winners and losers more sharply than almost any other sector this year.
This post breaks down what the index holds, how the weights reflect the underlying thesis, and where the tension points are heading into the second half.
What the Index Actually Owns
The portfolio is not a passive solar bet. The ten holdings span grid infrastructure, utility-scale solar manufacturing, regulated utilities, distributed solar, and power construction. The weight distribution reflects that deliberately:
- GE Vernova (GEV), 16%
- First Solar (FSLR), 15%
- NextEra Energy (NEE), 15%
- SolarEdge Technologies (SEDG), 11%
- Quanta Services (PWR), 8%
- Enphase Energy (ENPH), 8%
- NXT (NXT), 8%
- Argan (AGX), 7%
- Sunrun (RUN), 5%
- Fluence Energy (FLNC), 4%
GEV,
FSLR, and
NEE together account for 46% of the portfolio. That concentration is intentional. These three represent the most defensible positions in the energy transition: grid equipment manufacturing, domestic thin-film solar production, and regulated renewable development at scale.
The Top Three: Why They Anchor the Portfolio
GE Vernova (GEV) holds the largest single weight at 16%. The thesis here is straightforward: every megawatt of new generation, whether wind, solar, or gas peaker, needs grid infrastructure. GEV manufactures gas turbines, wind turbines, and grid equipment. The company benefits from the energy transition without being entirely dependent on policy support for any single technology. Demand for its electrification segment is structural, driven by data center load growth as much as decarbonization mandates.
First Solar (FSLR) at 15% is the domestic manufacturing play. FSLR produces cadmium telluride thin-film panels entirely in the United States, which insulates it from the tariff exposure that has crushed Chinese-supply-chain competitors. The Inflation Reduction Act's domestic content bonuses flow directly to FSLR's economics in a way they do not for most of the industry. The company has been expanding capacity aggressively, and its order book has historically extended years forward.
NextEra Energy (NEE) at 15% is the regulated anchor. NEE operates Florida Power & Light alongside the world's largest renewable energy development platform. The regulated utility base provides earnings predictability; the development arm captures growth. For an index that needs to hold through policy volatility, NEE's balance of contracted cash flows and growth optionality justifies its weight.
The Middle Tier: Differentiated Exposure
Quanta Services (PWR) at 8% is the pick-and-shovel position. Grid buildout requires physical construction, and Quanta is the dominant contractor for electric power infrastructure in North America. Revenue is less sensitive to technology cycles and more tied to the multi-decade grid modernization capex wave.
NXT at 8% and Argan (AGX) at 7% represent the power construction and development segment. AGX in particular has been a strong performer, building gas-fired and renewable power plants under fixed-price contracts. The company carries a clean balance sheet and has benefited from the surge in data center power demand driving new generation projects.
Fluence Energy (FLNC) at 4% is the battery storage exposure. Grid-scale storage is the missing piece of the renewable buildout, and Fluence operates as a software-enabled storage-as-a-service platform. The weight is modest, reflecting the company's earlier-stage profitability profile relative to the rest of the portfolio.
The Stress Points: SEDG and ENPH
The two names that require the most explanation are SolarEdge Technologies (SEDG) at 11% and Enphase Energy (ENPH) at 8%.
Both companies sell inverter and microinverter hardware into the residential and commercial solar market. Both have been under severe pressure. European residential solar demand collapsed faster than either company anticipated, inventory corrections ran deep, and competition from lower-cost Asian manufacturers intensified. SEDG in particular has gone through a restructuring, leadership changes, and significant margin compression.
The combined 19% weight in these two names is the index's most contested allocation. The bull case: residential solar adoption is a long-cycle story, U.S. demand remains structurally intact, and both companies have technology moats in power electronics that are not easily replicated. The bear case: the recovery timeline is uncertain, and the competitive dynamics in inverter hardware have permanently shifted.
Sunrun (RUN) at 5% adds further residential solar exposure through the installer and financing model rather than hardware. RUN's economics depend heavily on the cost of capital, making it sensitive to interest rate movements in a way the hardware names are not.
NAV 1074.66: Reading the Number
The index NAV of 1074.66 reflects a portfolio that has navigated a bifurcated sector. The heavy-infrastructure names, GEV, PWR, AGX, and NEE, have generally performed well as grid investment accelerated. The distributed solar names, SEDG, ENPH, and RUN, have been a drag.
The net result is an index that has held above its 1000 base level, but the composition of that performance matters. The index is not a pure solar play, and the NAV reflects that diversification working as designed.
What Drives the Index From Here
Three variables will determine the index's trajectory through the rest of 2026.
First, U.S. power demand growth. Data center construction is pulling forward electricity demand projections by years. Every major hyperscaler has announced multi-hundred-billion-dollar infrastructure commitments. That demand benefits GEV, NEE, PWR, and AGX directly.
Second, residential solar recovery. If SEDG and ENPH show stabilization in European volumes and U.S. installation rates hold, the 19% combined weight becomes a recovery catalyst rather than a drag. The next two quarters of earnings from both companies will be the clearest signal.
Third, policy durability. The IRA's domestic content provisions and investment tax credits underpin the economics of FSLR and NEE's development pipeline. Any legislative changes to those provisions would reprice the index meaningfully.
The ACCE Clean Energy index is not a bet on one technology winning. It is a bet on the physical infrastructure of the energy transition, with concentrated positions in the names most insulated from policy risk and most exposed to the structural demand surge from electrification. The SEDG and ENPH weights are the deliberate contrarian element, sized to matter if the recovery arrives, but not large enough to define the index if it doesn't.
The second half of 2026 will test whether that construction holds.
