Solar Equipment Makers Split Sharply in 2026 as Policy Winds Shift
Solar technology stocks told very different stories in 2026, with residential-focused equipment makers outperforming while a leading domestic module manufacturer lagged, according to a market recap published by Pluang.
SolarEdge Technologies (SEDG) gained 19% for the year, while residential solar peer Enphase Energy rose 13%. In contrast, First Solar (FSLR) fell 22% over the same stretch, a divergence the report attributed to shifting policy conditions affecting different corners of the solar supply chain.
The three companies occupy distinct positions in the industry. SolarEdge, based on its business description, sells power optimizers and DC-to-AC inverters — devices that convert the direct current produced by panels into usable alternating current — along with home battery storage products across the United States and Europe. Its fortunes are closely tied to residential and commercial installation demand.
First Solar, by comparison, manufactures thin-film photovoltaic (PV) modules — the panels themselves — serving utility-scale projects in the United States, France, India, Chile, and other markets. Manufacturers of this kind are more exposed to domestic manufacturing policy, project permitting timelines, and procurement cycles for large solar farms.
Recent trading underscored the volatility in the group. First Solar shares closed at $213.25, up 4.44% from the prior close of $204.18, valuing the company at roughly $23.1 billion. SolarEdge traded at $36.43, a 5.94% gain from its previous close of $34.39, giving it a market capitalization of approximately $2.28 billion — a fraction of First Solar’s, reflecting the steep declines SolarEdge shares have experienced from earlier highs.
The 2026 split illustrates how policy changes can affect solar subsectors unevenly: companies selling into utility-scale domestic manufacturing may respond differently to legislation than those tied to rooftop and storage demand in residential markets. Neither outperformance nor underperformance in a single year necessarily reflects the underlying operating trajectory of the businesses, which continue to report quarterly results against evolving demand conditions.
Solar is one of several technologies competing on cost in the power sector, alongside wind and natural gas. Its levelized cost of energy (LCOE) — the average cost per unit of electricity generated over a project’s lifetime — remains a key metric utilities weigh when adding new capacity, though financing terms and policy incentives frequently shift those calculations.
