First Solar Explained: How They Make Money, Ship 8.7 GW, And Why The Financials Matter for Utility-Scale Buyers

First Solar: The FAQ That Gets Straight to the Point

If you're evaluating First Solar modules for a utility-scale project, you probably have a few big questions. Maybe you’re trying to understand their business model — how they make money, why their shipment numbers matter, and whether their financial health signals stability or risk for your supply chain. I’m not a solar engineer or a financial analyst, but I do manage procurement for a mid-sized developer. So I’ve spent a lot of time digging into these questions — and honestly, it’s not always easy to find plain-English answers. This FAQ covers the stuff I wish someone had spelled out for me earlier.

Q1: How does First Solar actually make money?

Basically, they make money by selling thin-film cadmium telluride (CdTe) solar modules — specifically their Series 6 and Series 7 panels — to large-scale solar power plant developers, independent power producers (IPPs), and EPC contractors. Unlike most manufacturers who sell commodity crystalline silicon panels, First Solar owns its technology from R&D through manufacturing. That vertical integration means they capture margin at every step: raw material procurement, module production, and project sales. They also have a services arm (O&M, asset management) that adds recurring revenue. For a procurement perspective, this matters because it makes their pricing less volatile than silicon-based suppliers.

For a more detailed breakdown, First Solar’s investor page is a good starting point — but the TL;DR is: sell panels, build large-scale solar farms, manage operations, and collect steady service fees.

Q2: What does "First Solar module shipments H1 2024: 8.7 GW" actually mean?

It means in the first half of 2024, First Solar shipped 8.7 gigawatts (GW) of modules. That's a huge number — enough to power roughly 1.7 million homes annually if you're using typical utility-scale averages. For context, that's about a 30% increase over H1 2023. In procurement terms, 8.7 GW represents about 20-25 million modules (depending on the wattage per panel). This scale gives them serious leverage in raw material sourcing, which helps keep prices stable. It also means they have a 66 GW backlog — orders booked for future delivery — so developers aren't worried about capacity availability in the short term. For a buyer, this is a green flag: strong demand signals reliability.

You can verify shipment data in their Q2 2024 earnings release.

Q3: Why should I care about First Solar's financials if I'm just buying modules?

Because financial health is a proxy for supply chain stability. When a manufacturer has strong gross margins (they reported 55-60% for Series 6/7 in recent quarters) and a healthy backlog, they're less likely to cut corners or delay shipments during volatile market conditions. I've been burned by suppliers who looked good on paper but couldn't deliver when raw material prices spiked. First Solar's return on invested capital (ROIC) is around 20-25% — which is excellent for manufacturing. That tells me they're not just selling panels; they're running a sustainable business that can reinvest in R&D and capacity. If you're planning a large-scale project with multi-year timelines, that matters.

Financial anchors: FY2024 net sales were roughly $4.4 billion, net income around $1.2 billion, and their gaap gross margin was 55-60% (from First Solar's FY2024 Annual Report, March 2025).

Q4: I keep hearing about Series 6 and Series 7. What's the difference for a buyer?

Series 6 is a larger format, higher wattage panel — typically 460W–470W — designed for utility-scale ground-mount projects. Series 7 is slightly smaller (400W–420W range) but offers higher efficiency (up to 19.0%) and is better suited for projects with space constraints or where higher efficiency per square meter drives value. From a procurement standpoint, the key decision factors are: module size compatibility with racking, energy yield per watt (both have similar degradation rates under 0.5%/year), and price per watt. Series 7 tends to have a small premium due to higher efficiency, but the gap is narrowing. Check the Series 7 datasheet for exact specs.

Pro tip for procurement: Ask about the annual degradation rate. First Solar's thin-film modules are known for under 0.5% annual degradation over 30 years, which is significantly better than most c-Si panels (which are typically 0.55-0.70%). Over a 25-year PPA, that's a measurable difference in energy yield.

Q5: What are the biggest risks or downsides with First Solar?

Nothing is perfect. The main risks I've seen:

• Technology concentration: They're 100% thin-film CdTe. If there's a breakthrough in perovskite or silicon that dramatically lowers costs, First Solar's tech could face pricing pressure. That said, they're investing heavily in R&D (~$300 million in FY2024).
• Regulatory dependency: U.S. tariffs on imported solar cells and Section 201 tariffs create pricing advantages for domestic manufacturers like First Solar. If trade policy shifts, their pricing edge could shrink.
• Long-term supply: With a 66 GW backlog, some developers worry about allocation priority. Smaller buyers might get squeezed if they're not a strategic account. My advice: book early and negotiate allocation clauses.

I’m not an engineer, so I can’t speak to the technical nuances of thin-film vs. crystalline silicon performance in specific environments. But from a procurement perspective, these are the risks you need to factor into your vendor evaluation.

Q6: Is First Solar a good fit for my project?

If you're building a large-scale (>50 MW) ground-mount solar farm in the U.S., Western Europe, or India — probably yes. Their modules are purpose-built for utility-scale, and their financial stability is a legitimate safety net. If you're doing a small commercial rooftop (<1 MW), their pricing might not be competitive (they focus on large-format modules). And if your project requires the highest possible efficiency regardless of cost — that's still a crystalline silicon strength. But for the vast majority of utility-scale buyers, First Solar is a reliable baseline worth serious consideration.

Bottom line: Informed clients make better decisions. I’d rather spend 30 minutes explaining how their financials work than see a developer commit to a module supplier without understanding the full picture. Take it from someone who’s managed eight-figure procurement budgets — the extra homework pays off.
