Sixty-six percent of people, when presented with three distinct tiers of pricing, will select the middle option regardless of the specific technical merits of the alternatives.

Marcus was the facility manager for a distribution center in Truganina. His roof was roughly 4,000 square meters of corrugated steel. He was under significant pressure from his board to reduce the facility’s carbon footprint and, more urgently, to stabilize a monthly electricity bill that fluctuated between $12,000 and $18,000.

Marcus was a diligent man. He invited three different providers to submit proposals. Each provider returned a document that looked remarkably similar. There were three tiers: a “Standard” 100kW system, an “Optimal” 250kW system, and a “Premium” 450kW system.

Marcus looked at the “Standard” and felt it was too conservative. He looked at the “Premium” and felt it was an overreach. He chose the “Optimal” 250kW system. He felt he had exercised good judgment. He believed he had found the balance between caution and ambition.

In reality, the 250kW system was the only thing the provider had ever intended to sell him. The other two tiers were architectural decoys, designed to frame his choice.

The Splinter of Risk Aversion

I have spent the morning with a magnifying glass and a pair of precision tweezers. A sliver of Victorian ash, no longer than a millimeter, had lodged itself under the skin of my right thumb while I was stripping the lead paint off an old chemist’s sign.

Until that sliver was removed, every action-holding a brush, gripping a chisel, turning a door handle-was calibrated around avoiding that specific point of pain. Business decisions are rarely any different. A CFO or an operations manager carries a “splinter” of risk aversion.

They do not want to be the person who bought the cheapest, least reliable option. They also do not want to be the person who overspent on a luxury they didn’t need. They navigate by avoiding the pain of the extremes.

The industry understands this perfectly. They build menus where the middle option is the high-margin target, the low option is a stripped-down deterrent, and the high option is a gold-plated anchor designed to make the middle look like a bargain.

The Fallacy of the Average Need

This rigging of the menu is particularly prevalent in the world of solar energy. Because the technology can feel opaque and the metrics-kilowatt-hours, peak yield, degradation rates-are often confusing to the uninitiated, the buyer leans on the structure of the proposal rather than the data within it.

They assume that if a company offers three choices, the one in the middle represents the “average” need. This is a fallacy. In commercial engineering, there is no such thing as an average need. There is only the specific requirement of the building and its operational load.

Marcus’s 250kW “Optimal” choice was a disaster. The system was too large for his base load during the shoulder months, meaning he was exporting vast amounts of energy to the grid for a pittance. Simultaneously, the system was too small to provide the surge capacity he needed during his peak processing hours in the afternoon. He had chosen the middle of a menu, but the menu had nothing to do with his roof.

When we look at the way commercial solar approaches these problems, the contrast is stark. Engineering-led firms do not offer menus. They do not give you a “Silver, Gold, Platinum” choice because the physics of the site dictates a singular, optimal solution.

If the data shows that a 183kW system is the point of diminishing returns for your specific LCOE (Levelized Cost of Energy), then a 200kW system is an error and a 150kW system is a missed opportunity.

The “Goldilocks” approach to purchasing is a defense mechanism against complexity. If you give a buyer twenty options, they suffer from choice paralysis. If you give them two, they feel pressured. If you give them three, you give them a narrative.

The story of the middle option is the story of the “sensible professional.” It is a comfortable story. It allows a manager to report to a board that they didn’t take the highest risk, nor did they settle for the lowest quality.

Stripping Back the Paint

I remember a sign I restored for a bank in Ballarat years ago. It had three different layers of gold leaf applied over various decades. Each signwriter had tried to “balance” the previous work.

By the time I got to it, the original intent of the font was buried under layers of compromise. I had to strip it back to the original timber to see what the sign was actually trying to say. This is exactly what a business must do with a tiered proposal. You have to strip away the “Gold” and “Platinum” labels and look at the underlying engineering.

When you ask these questions, the “middle option” often starts to look like a collection of generic parts slapped together to hit a price point. The industry relies on the fact that most buyers will not look at the wiring. They will look at the bottom line of the middle column.

The Predatory Decoy Effect

This is where the “decoy effect” becomes truly predatory. Often, the “Premium” option is priced so exorbitantly that it serves no purpose other than to make the middle option appear significantly more affordable.

If the jump from Tier 1 to Tier 2 is $40,000, but the jump from Tier 2 to Tier 3 is $120,000, the buyer perceives Tier 2 as a massive win. They feel they are getting almost the same value as the “Premium” for a fraction of the upgrade cost. They aren’t. They are just being moved into the box the seller already checked.

They are mapping the shadow cast by the neighbor’s parapet wall at 3:00 PM in July. They are checking the age of the main switchboard and the capacity of the local transformer.

This level of detail is the equivalent of the precision tweezers I used on my thumb. It is meticulous, and it is the only way to remove the “splinter” of inefficiency. A system that is “mostly right” is fundamentally wrong over the course of two decades.

If a 200kW system is 5% less efficient than a perfectly engineered 190kW system due to voltage rise or thermal degradation, that 5% compounds every single day for twenty-five years.

In the Victorian commercial sector, the complexity of DNSP (Distributed Network Service Provider) requirements adds another layer to this. You cannot simply pick a “middle option” if the local grid won’t allow that much export, or if it requires specific reactive power control that the “standard” inverter in your chosen tier doesn’t handle well.

A tiered proposal often glosses over these technical hurdles until after the deposit is paid. An engineering-led approach tackles the DNSP negotiation before the first panel is even selected.

We must stop treating solar as a commodity and start treating it as a specialized machine. You wouldn’t buy a custom manufacturing line by picking the “middle” option from a three-page brochure. You would specify every gear, every motor, and every sensor to match your production output. Why should the power plant on your roof be any different?

From Buyer to Partner

The shift from being a “buyer of menus” to a “partner in engineering” is a psychological hurdle. It requires admitting that the “safe middle” might actually be the most expensive mistake you can make. It requires looking at the LCOE rather than just the CAPEX.

The Levelized Cost of Energy tells you the true price of every kilowatt-hour the system will produce over its life. Often, the “middle option” has a higher LCOE than a more expensive, better-engineered system because the cheaper components fail earlier or produce less power per watt installed.

The “safe” choice had become a series of expensive retrofits. I think back to that chemist’s sign. The timber was sound, but it had been neglected. It didn’t need a “middle-of-the-road” coat of paint. It needed a specific type of primer to seal the old oils, a specific weight of gold leaf to handle the exterior exposure, and a steady hand to apply it.

There was no “Silver” version of that job that would have lasted. There was only the right way to do it.

The next time you are presented with three options for a commercial project, ask yourself why those specific three exist. Ask what data points defined those boundaries. If the answer is “we find most people like this one,” you are looking at a menu, not a solution. You are being steered by the compromise effect.

The industry thrives on the fact that we are uncomfortable with the extremes. They know we will walk past the cheap and fear the expensive. They build the middle to be a trap.

The only way out is to demand a system built from the data up, not from the brochure down. When the engineering is right, there are no tiers. There is only the system that works, precisely and without compromise.
