Every week I get asked the same question: "How much is it going to cost?" My honest answer is always: it depends.
That sounds like a dodge. But after six years as a procurement manager for a 45-person renewable energy and industrial storage company, I've learned that "it depends" is the only useful starting point. I've watched a $2,000 difference in a quote turn into a $15,000 problem, and I've seen a "premium" option save more than a budget option over the life of a contract.
This guide covers the three B2B purchasing decisions I get asked about most: Maxeon solar panels, Level 2 EV chargers, and steel coil racking systems. Different situations, different answers. But the underlying questions are the same.
Before the Numbers: What Are You Actually Buying?
A solar panel isn't just a panel. An EV charger isn't just a box on a wall. A steel coil racking system isn't just steel shelves. Each one has a list of "small" details that decide whether your project lands on budget or not.
Ask yourself: am I choosing a delivered product, or am I choosing a system that someone will have to install, operate, and maintain? Because the second question changes the math.
Scenario 1: You're Buying Solar Panels for a Commercial Project
If you're pricing a commercial solar array, you'll probably look at premium and mainstream modules. Maxeon Solar Technologies is one of the premium names. The company makes IBC solar cells and panels with a 40-year linear power warranty, and the efficiency numbers are real: 24%+ on some products, with lower temperature-related losses than conventional cells.
But before you compare prices, you need to know where the panels come from.
Where Are Maxeon Solar Panels Made?
As of early 2025, Maxeon is headquartered in Singapore, but its main manufacturing footprint is in Malaysia and Mexico. The IBC cell production happens in Malaysia; much of the module assembly for North American projects is done in Mexico. That matters for two reasons: lead times and trade rules.
For a U.S. project, a panel assembled in Mexico usually has a shorter shipping route than one from Southeast Asia. But don't rely on that assumption—supply chains change. I ask for the country of origin on every quote, not just because of tariffs, but because a "three-week lead time" can become six if the panels are coming from the other side of the Pacific. As of now, I don't see U.S.-assembled Maxeon panels in the supply chain. If you need domestic content for a government incentive, that alone may disqualify them. Verify it for your specific project before you fall in love with the technical spec.
Standard Solar Panel Dimensions: Don't Assume You Know
Here's a trap I've hit twice: I planned a layout using what I thought was the standard solar panel dimensions for commercial modules. The market is not as uniform as it used to be. There are still common sizes, but they're more like a range:
- 60-cell residential/commercial: roughly 65" x 39" (1,660 x 992 mm)
- 72-cell commercial: roughly 77" x 39" (1,960 x 992 mm)
- Newer high-power large-format modules: 93" x 49" or larger, especially utility-scale
Maxeon panels are not all the same as the generic "standard" size; some models are wider or longer. That's irrelevant until you're working with a constrained roof or a pre-engineered racking layout. Then a 10 cm length difference changes your row spacing, ballast calculation, and cable tray routing. Get the mechanical datasheet before you commit to a racking system.
Is Maxeon Worth the Premium? It Depends on Two Questions
I've sat through a lot of "why not buy cheaper panels" conversations. My answer comes down to two questions:
1. Who will own the system in 25 years? If you're a developer selling the project after commissioning, the low up-front cost looks great in project NPV. If you're the owner paying the electricity bill for 30 years, a lower degradation rate and a 40-year warranty can beat the cheap panel on total cost of ownership.
2. How constrained is the site? If you have open ground, a 21% efficient panel is fine. If the roof is small and the utility rates are high, you need the 24% panel to get enough kilowatt-hours on a limited footprint. That's where Maxeon's IBC technology gets interesting. It also performs better in high-heat and partial-shade conditions than many conventional modules, which matters if you're installing on a low-pitch commercial roof with HVAC units casting shadows.
One caution from my experience: when comparing module quotes, use the same inverter, mounting, and warranty assumptions. I almost approved a budget module because it was $0.08/W less, until I noticed the quote didn't include the manufacturer's required extra ground-fault protection. That "cheap" option would've added $12,000 to the balance of system.
Scenario 2: You're Adding a Level 2 EV Charger
Now let's talk about the question I get from facilities managers every month: how much does a Level 2 charger cost to install?
Short answer: most commercial Level 2 installations I've seen land between $2,500 and $8,000 per port, not counting network management fees or software subscriptions. But that range hides a lot of variation.
Here's a rough breakdown from projects I've actually managed:
- Charger unit hardware: $500 to $2,500 per connector
- Electrical material, conduit, breakers, and permit: $800 to $3,000
- Labor, including trenching if needed: $1,000 to $3,500
The biggest variable is the distance from the electrical panel to the charging spot. I paid $3,400 for a charger that was 15 feet from the panel, and $9,100 for one that required a 180-foot trench, a subpanel, and demolition of part of a parking lot. If you're planning a fleet depot, ask for a load calculation first. You may need service upgrades that double the cost. Also, NEC 625 now requires little things like load management and proper grounding systems. Don't let anyone quote you "just a plug and cord" unless your EVSE actually supports that.
The lesson: you're not buying a charger. You're buying an electrical circuit with a charger on the end. Get a quote that itemizes the circuit. And ask for the total installed cost, not just hardware.
Scenario 3: You're Sourcing a Steel Coil Racking System
I'll admit: steel coil racking is not as exciting as solar panels or EV chargers. But it's the one where I've seen the biggest budget surprises. A steel coil racking system has hidden costs that don't show up in the per-rack price.
One job we bid had a low quote that was 22% below the next vendor. It looked like a no-brainer. Then I read the fine print: no seismic bracing, no coil cradles, no end-of-aisle protection, and installation was quoted "per rack" without floor anchors. The so-called cheaper system would've been about $3,500 more than the honest quote once we added the missing components.
So when you compare steel coil racking quotes, make sure each vendor includes:
- Coil capacity rating and cradle width for your actual coil sizes
- Seismic bracing and floor anchoring, if required by local code
- End-row protection and aisle guards
- Installation labor, not just delivery
- Finish/coating specification for the environment
One rule I follow now: ask every vendor to write down what is not included. The vendor who lists all the extras upfront—even if the total is higher—usually costs less in the end. That's not politeness. It's procurement math.
The Takeaway: Use Total Cost, Not First Price
I still kick myself for an early mistake: choosing a vendor because the unit price was lower, then paying $1,200 for compatibility adapters I didn't anticipate. If I'd asked one more question, I could've avoided the whole problem. Now our procurement policy requires every quote to include a complete itemized list before it goes to management.
Are you buying Maxeon solar panels, a Level 2 charger, or a steel coil racking system? The answer doesn't have a single number. But if you ask the right questions—the country of origin and dimensions, the circuit distance, the seismic bracing—you'll at least know the real cost before you sign.
And that, in my experience, is the whole game.
