Is TAN a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The case for TAN is simple: low-cost, diversified exposure to MAC Global Solar Energy Index at a 0.70% expense ratio, anchored by names like NXT, FSLR, ENLT. If that is the exposure you want and you do not already own most of it through another fund, TAN is a strong core holding. The catch is concentration in its top names and overlap with broad-market funds you may already hold. Whether it is a buy comes down to whether you want MAC Global Solar Energy Index and at what cost. Not a recommendation; Walnut is not an investment adviser.
What are you buying with TAN?
TAN tracks the MAC Global Solar Energy Index, holding a focused set of companies across the solar value chain (panels, inverters, trackers, installers, and financiers) at a 0.70% expense ratio. Unlike a broad clean-energy fund such as ICLN, TAN is almost entirely solar, which makes it a purer but more volatile way to invest in the theme.
Largest holdings (approximate as of mid-2026; verify on Invesco's fund page):
| Rank | Ticker | Company | % of TAN | |
|---|---|---|---|---|
| 1 | NXT | Nextracker | ~10.2% | |
| 2 | FSLR | First Solar | ~9.4% | |
| 3 | ENLT | Enlight Renewable Energy | ~6.7% | |
| 4 | ENPH | Enphase Energy | ~6.6% | |
| 5 | SEDG | SolarEdge Technologies | ~5.1% | |
| 6 | RUN | Sunrun | ~4.7% | |
| 7 | DORL | Doral Group Renewable Energy Resources | ~4.4% | |
| 8 | NOFR | O.Y. Nofar Energy | ~4.0% | |
| 9 | HASI | HA Sustainable Infrastructure Capital | ~3.7% | |
| 10 | TE | T1 Energy | ~3.4% |
What's the case for TAN?
TAN is the Invesco Solar ETF, the largest US-listed pure-play solar fund, tracking the MAC Global Solar Energy Index at a 0.70% expense ratio. It holds a concentrated basket of solar names such as Nextracker, First Solar, Enphase Energy, SolarEdge, and Sunrun, so it is a targeted bet on solar economics rather than broad clean energy. Its distinguishing trait is purity: TAN is nearly all solar hardware, developers, and financiers, which makes it far more volatile than a diversified renewables fund like ICLN.
In its favour: it gives you MAC Global Solar Energy Index exposure in one ticker at a 0.70% expense ratio, which is simple to hold and cheap to own.
What should you weigh before buying TAN?
- Cost vs alternatives: 0.70% is the fee; compare it to funds tracking a similar index.
- Concentration: check how much of TAN sits in its largest holdings (NXT, FSLR, ENLT).
- Overlap: if you already own a broad-market fund, you may already hold much of this.
- Tracking scope: TAN only gives you MAC Global Solar Energy Index; it will not capture what sits outside that index.
How do you decide if TAN is a buy?
The useful question is rarely “will TAN go up?” It is “does this exposure fit my plan, at a cost I am happy with, without doubling up on what I already own?” Walnut connects your real brokerage so you can see exactly how TAN would overlap with your current holdings, analyze it by chatting through Claude or ChatGPT, and place any trade yourself. You stay in control.
The bottom line on TAN
The bottom line: TAN is a low-cost core building block for MAC Global Solar Energy Index exposure, not a tactical bet on a single name. If you want MAC Global Solar Energy Index exposure and the 0.70% fee is competitive for you, it does its job well. If you already own that exposure through another fund, adding it mostly doubles a fee without adding diversification. Decide from your goal and your existing holdings, not from where the market sat last week. Walnut is not an investment adviser.

FAQ
Is TAN a good ETF to buy?
+
Walnut is informational, not investment advice. Whether TAN fits depends on your goals, time horizon, and what you already hold. It tracks MAC Global Solar Energy Index at a 0.70% expense ratio, so the questions that matter are whether you want that exposure, whether you already own it through another fund, and whether the cost is competitive for what it does.
What does TAN actually hold?
+
TAN tracks MAC Global Solar Energy Index. Its largest positions include NXT, FSLR, ENLT, ENPH, SEDG and others (approximate, verify on Invesco's fund page). The holdings are what you are really buying, not the ticker.
What is TAN's expense ratio?
+
0.70% as of mid-2026. Over decades, the expense ratio is one of the few things you can control, so it is worth comparing against close alternatives that track a similar index.
Does TAN pay a dividend?
+
TAN distributes a dividend with an approximate yield of ~0.3% (mid-2026). See the TAN dividend page for how distributions work. Verify the current figure with Invesco.
What are the risks of buying TAN?
+
Like any index ETF, weigh concentration (how much sits in the top holdings), overlap with funds you already own, and whether MAC Global Solar Energy Index matches the exposure you actually want. TAN only gives you MAC Global Solar Energy Index, not what sits outside it.
How do I decide if TAN is right for me?
+
Start from your goal, then check four things: what TAN holds, its cost versus alternatives, how much it overlaps with what you already own, and whether the exposure fits your time horizon and risk tolerance. Walnut can analyze the overlap against your real holdings; you keep your broker and approve any trade.
