You know the pattern. A new technology appears – solar plus storage, for example – and after the peak of inflated expectations comes the inevitable crash. Hype fatigue sets in. Early adopters nurse bruised shins. And then, right on cue, a study lands like a perfectly aimed rotten tomato.

The headline screams: “Home batteries are not economically viable in [cold, high-latitude country].”

Clicks flood in. Politicians who never liked subsidies wave the paper. Media moves on. Industry experts scream into the void: “But they used the wrong system sizing. They ignored price arbitrage. They omitted the backup power feature. They left out the reserve market.”

None of that matters. The damage is done. The headline becomes truth.

This is not an accident. It is not a conspiracy. It is the Trough of Disillusionment – that long, dark valley in the Gartner Hype Cycle – doing exactly what it always does. And the study that emerges there is not flawed by chance. It is flawed by design, because the incentives of academia, media, and politics align perfectly to reward short‑sighted, attention‑grabbing, methodologically convenient research.

The cycle, briefly

• Peak of Inflated Expectations – Every story is a feelgood breakthrough. Caveats buried. (Remember when solar would be free by 2020?)
• Trough of Disillusionment – The backlash. Now every story is a feelbad exposé. Headlines simplified. Rebuttals buried.
• Slope of Enlightenment – Finally, honest, system‑optimized analysis appears. But it gets no headlines.

The research we are discussing arrived right on schedule: during the trough, immediately after capitulation – that moment when even believers start to doubt. And it was built to thrive there.

Anatomy of a trough‑optimised study

Take a specific product category: a residential solar‑plus‑battery system in a northern climate. A properly sized system might pair 6–8 kWp of solar with 5–10 kWh of storage, enabling 24‑hour self‑consumption, price arbitrage in a volatile intraday market, reserve market participation, and full blackout protection.

Now watch what the trough‑optimised study does instead:

• Choose a deliberately mismatched ratio – Small solar (e.g., 4 kWp) paired with a very large battery (e.g., 13.5 kWh). The battery will rarely fill. The economics crater.
• Omit key revenue streams – No intraday arbitrage. No reserve market. Those are “too complex” or “outside the scope.”
• Ignore value‑added features – Full disconnect capability during grid outage? Not modelled. Resilience has no price in the spreadsheet.
• Declare the whole category uneconomical – Then let the media generalise.

The internal math is correct. The paper passes peer review – because peer review checks internal consistency, not real‑world relevance. The junior researcher gets their credits, graduates faster, and moves on. The university press office gets a clickable headline. The media gets its outrage bait. The skeptical cabinet gets a scientific fig leaf.

No one is evil. Everyone is rational – inside a broken system.

Why does this always happen in the trough?

Because the trough is where capitulation meets opportunism.

• Capitulation means that investors, homeowners, and even early adopters are tired of waiting for the promised payback. They want someone to tell them it was all a waste. Bad news sells.
• Opportunism means that a junior researcher who needs quick publications can guarantee a negative result by simply choosing the wrong product configuration. A positive, nuanced result would require careful optimisation – and might not be newsworthy anyway.

The choice of product reveals the cycle phase.

• In the Peak of Inflated Expectations, studies use idealised, oversized solar arrays with tiny batteries – because that maximises the feelgood headline.
• In the Trough of Disillusionment, studies use mismatched, undersized solar with oversized, expensive batteries – because that guarantees the feelbad headline.
• In the Slope of Enlightenment, you finally see studies that test actual product categories: correctly sized systems, multiple revenue streams, real backup value.

But the slope gets no front page. The trough always wins the attention war.

Generalising the pattern

This is not about solar. It is not about batteries. It is about any product category that goes through the hype cycle – electric vehicles, heat pumps, green hydrogen, modular nuclear reactors, even software platforms.

Watch for the moment right after capitulation. That is when the “bullshit in, bullshit out” research appears. It will have the following fingerprints:

1. A product configuration that no competent practitioner would install – because it is deliberately suboptimal.
2. Omitted revenue streams or value drivers – the very things that make the product viable in practice.
3. A sweeping, categorical conclusion – “X is not economically viable in Y.”
4. A media headline that erases all caveats – and a buried correction that almost no one reads.

And it will work. Every time.

Because the system is not designed to reward truth. It is designed to reward velocity – of publication, of clicks, of political points. The junior researcher who plays that game is not a villain. They are a product of the machine. The fault lies with a machine that measures what is easy, not what is right.

What to do about it

If you are an investor, a policymaker, or a homeowner: do not trust the headline of a trough‑phase study. Look for three things instead:

• Is the product configuration realistic? Ask a practitioner, not a paper.
• Are the revenue streams included? Arbitrage, reserves, resilience – if missing, the conclusion is worthless.
• Who benefits from the conclusion? A researcher needing credits? A media outlet needing clicks? A politician needing cover?

The trough will always produce garbage. You do not have to eat it.
