TAN’s 82% Rally Masks a Quiet $3,350 Tax on $50,000 Over a Decade

Solar bulls love to point at the 12-month chart for Invesco Solar ETF (NYSEARCA:TAN) and call it a comeback story. The fund is up 82.81% over the past year. What that chart will not show you is the quiet tax the fund takes off the top every year you hold it, the concentration risk packed into a handful of solar names, and the five-year hole that still has not been filled.

What You Are Actually Paying

TAN’s prospectus, filed June 10, 2026, is the operative document for current holders. The widely cited net expense ratio on the fund sits at roughly 0.67%. On a $10,000 position, that is about $67 skimmed every year, in good years and bad. Hold $50,000 for a decade and you are looking at roughly $3,350 in fees before any compounding drag on the lost dollars.

Now stack that against a broader clean energy peer like iShares Global Clean Energy ETF (NASDAQ:ICLN), which carries an expense ratio around 0.41%. Same $10,000, about $41 a year. The annual gap looks trivial. Run it across 20 years on a growing balance and the fee differential alone can eat into a meaningful slice of terminal wealth, without TAN delivering the outperformance to justify the premium.

The Part the Factsheet Does Not Highlight

The sticker fee is the easy cost. The harder one is what TAN’s structure does to your return. The fund tracks a narrow solar index and concentrates exposure in a small lineup of solar manufacturers and installers, including First Solar (FSLR) and Enphase Energy (ENPH), plus names like Nextpower and Enlight Renewable Energy. That concentration cuts both ways: it produced TAN’s recent 19.32% year-to-date pop, and also the 11.13% drawdown in the past month alone.

Zoom out and the structural drag becomes harder to ignore. Over the past five years, TAN is down 30.6%. ICLN, broader and cheaper, is down 3.86% over the same five-year window. First Trust NASDAQ Clean Edge Green Energy ETF (NASDAQ:QCLN) sits at down 5.53%. TAN holders paid the highest fee for the deepest hole.

There is also a narrative cost building underneath the price. Recent coverage flagged a structural rotation in clean-energy capital toward nuclear power, with one June 2026 piece arguing that “Major tech companies are increasingly securing nuclear power deals for reliable, 24/7 energy, making nuclear investments more aligned with AI growth”. A separate June comparison concluded ICLN’s “broader portfolio, lower expense ratio, and higher asset under management” beat TAN’s concentrated solar bet.

The Cheaper Mirror

If the thesis is clean energy, ICLN gives you a broader basket at a lower fee, with a steadier five-year track record. QCLN spreads across solar, EVs, batteries, and grid plays, and beat TAN over both one year (up 92.04%) and five years. The trade-off is real: neither fund is a pure solar bet. If you specifically want a basket dominated by panel makers and inverter companies, TAN is the cleanest expression. You are paying for purity, not performance.

What This Means for You

The question worth asking is whether the concentrated, higher-fee version of the clean-energy bet is the one you actually want to own. If a cheaper, broader ETF gets you most of the exposure with less fee drag and less single-sector whiplash, the burden falls on TAN to justify the premium. Over the past five years, it has not.
