Latest / Energy Economics with Fexingo: Oil Prices, Renewables, and the Cost of Power / Why Enphase and First Solar Are Crashing While Oil Holds Steady
Transcript
- Lucas: So it's July 4th, 2026. Markets are actually open for a half day, and we've got a real head-scratcher playing out in energy stocks. WTI crude is sitting around sixty-nine dollars a barrel, down maybe two and a half percent on the week, but the big oil companies — Exxon, Chevron — are basically flat. Meanwhile, clean energy stocks are getting hammered. Luna: Hammered is putting it mildly. Enphase is down nine and a half percent in five days. First Solar off six percent. That's not a dip — that's a rout. Lucas: Right. And the divergence is striking because a year ago the narrative was that high oil prices would accelerate the renewable transition, and that clean energy stocks would benefit from both the Inflation Reduction Act and the general push for energy independence. Instead, we're seeing the opposite. Luna: So what changed? Because the macro backdrop hasn't exactly flipped overnight. Oil is still elevated by historical standards, inflation is still a concern. Lucas: The thing that changed most directly for solar stocks — and for Enphase and First Solar specifically — is the interest rate environment. The ten-year Treasury yield has been grinding higher, and the latest core PCE print, which came out in early June for May, showed inflation running at two point six percent year-over-year. That's above the Fed's target, and the market is pricing in higher for longer rates. Luna: And solar is uniquely sensitive to rates, isn't it? Because the business model relies on project finance. Lucas: Exactly. Most residential solar installations in the US are financed through loans or leases. When rates go up, the monthly payment on a twenty-year solar loan goes up, and the economics for the homeowner get worse. Enphase makes microinverters — the component that sits behind every solar panel — so they're directly exposed to the volume of residential installations. If installations slow because financing is more expensive, Enphase's revenue takes a hit. Luna: And First Solar is more utility-scale, but they're also rate-sensitive. Their customers are project developers who borrow at floating rates or need to lock in long-term fixed-rate debt. The cost of capital for a two-hundred-megawatt solar farm has gone up substantially. Lucas: Precisely. First Solar's panels are used in large ground-mount systems, and those projects have thin margins to begin with. The Internal Rate of Return on a utility solar project is typically in the six to eight percent range. If your cost of debt goes from four to six percent, that IRR gets squeezed, and some projects get deferred or canceled. Luna: There's also an inventory glut. I was looking at the latest data from the Energy Information Administration — there's been a flood of Chinese solar panels entering the US market over the past year as manufacturers try to get ahead of potential tariff increases. That's weighing on panel prices and hurting First Solar's pricing power. Lucas: Right. So you've got a double whammy: demand-side pressure from higher rates, and supply-side pressure from excess inventory. For a company like First Solar, which competes on both technology and price, that's a tough environment. And the market is repricing those stocks accordingly. Luna: Let's talk about the oil side, because the relative stability there is also interesting. WTI at sixty-nine, Brent at seventy-two — we're not in a panic, but we're also not seeing a big rally. Lucas: The oil market is in a kind of uneasy equilibrium. OPEC+ has been managing supply, and there's been some geopolitical noise — Iran export premiums, some tanker disruptions — but nothing that's really spiked prices. The demand outlook is actually fairly solid: US gasoline consumption is holding up, and summer driving season is in full swing. But the bigger picture is that the market has accepted that oil is going to trade in a sixty-five to seventy-five range for now. Luna: And the big oil companies are generating huge free cash flow at these levels. Exxon is yielding over three percent, buying back stock. Chevron too. So investors are happy to hold them even if the stock price doesn't move much. Lucas: That's the key difference. Oil stocks are cash flow machines right now, with strong balance sheets and shareholder returns. Solar stocks are growth stories that require cheap capital and rising demand. When rates are high and growth is uncertain, the market favors the cash flow story. Luna: So what does this mean for the clean energy transition longer term? Because these are short-term market dynamics, but the policy framework — the IRA, state-level renewable mandates — hasn't changed. Lucas: That's a really important point. The secular trend toward renewables is still intact. The IRA's tax credits are production-based, not rate-dependent. But the pace of deployment is going to be slower if financing costs stay elevated. We might see a pause in new project announcements, or a shift toward projects that can lock in lower rates through corporate PPAs or government-backed loans. Luna: And that could actually benefit the larger, better-capitalized players like NextEra, which has a huge balance sheet and can self-finance projects. NextEra is only down point two percent this week. So the market is distinguishing between the enablers and the pure plays. Lucas: Exactly. NextEra is a regulated utility plus a large renewables developer. They have a lower cost of capital than a standalone solar panel maker. So they can weather the rate environment better. That's why their stock is flat while Enphase is down nine percent. Luna: If walking through the economy with us has made something click — like the connection between interest rates and solar stocks — that's exactly the kind of insight we try to deliver every episode. And the reason we can do this without ads is listener support. So if today was useful, you can keep it going at buy me a coffee dot com slash fexingo. Lucas: Yeah, that's it. We don't do sponsors, we don't do endorsements. Just straight analysis. And the coffee thing is genuinely how we stay free. So if you're getting value, it helps. Luna: Alright. Back to the numbers. One thing I want to flag is the inflation breakeven — the ten-year breakeven is stuck at two point two three percent. That's essentially flat for months. The market doesn't see inflation going much lower, but it also doesn't see it spiking. That's a Goldilocks scenario for oil. Lucas: It is. If inflation stays elevated but not accelerating, the Fed stays on hold, and that's actually fine for commodity prices. The risk for solar is if rates stay high enough to choke off project financing. But the breakeven suggests the market expects a slow grind, not a collapse. Luna: So where does that leave Enphase and First Solar from a valuation perspective? Enphase is trading around forty-three dollars, which is down from its highs above three hundred in 2021. First Solar at two twenty-five is off its highs too, but not as dramatically. Lucas: Enphase's price to earnings ratio has compressed significantly, but it's still not cheap on a forward basis because earnings estimates have been cut. The company preannounced weaker guidance earlier this year. First Solar, on the other hand, has a massive backlog of panel orders, so their earnings visibility is better. That might explain why the sell-off is less severe in percentage terms. Luna: But if rates stay high for another year, and the inventory glut persists, those backlogs could get pushed out. That's the risk. Lucas: It is. And the market is pricing that risk in right now. The interesting thing will be the second-quarter earnings calls in a few weeks. If Enphase management sounds cautious about the back half of 2026, we could see another leg down. If they say demand is stabilizing, that could be the bottom. Luna: And for oil, the next catalyst is probably the OPEC+ meeting later this month. Any signal that they're going to increase supply could push WTI below sixty-five. But if they hold steady, we stay in this range. Lucas: So the bottom line: the divergence between solar and oil is a story about the cost of capital, not about the energy transition failing. Solar stocks are getting crushed because their business model is rate-sensitive, and the Fed isn't cutting. Oil stocks are stable because their cash flows are strong at current prices. It's a tale of two balance sheets. Luna: And that's something to keep in mind if you're looking at energy exposure in your portfolio. The sector is not monolithic. What works for oil doesn't work for solar, and vice versa. Lucas: Exactly. We'll be watching those earnings reports closely. Thanks for listening, and we'll be back tomorrow with more.
