First Solar, First Solar Cell, First Planet in Solar System, and Wind Turbine Costs: A Procurement FAQ

I am a procurement manager at a renewable energy development company. For the last six years, I have reviewed utility-scale solar module offers and wind turbine quotations, and I have tracked the costs through financial close. I am also the person who has to explain why "First Solar" and "first solar cell" are not the same search. Here are the questions I would answer for a colleague trying to cut through that confusion.

FAQ: First Solar, wind turbine costs, and the searches that mix everything up

1. Is First Solar the first planet in solar system?

No. The first planet in solar system—if that phrase means closest to the Sun—is Mercury. First Solar is a manufacturer of thin-film cadmium telluride solar modules. The similarity is only in words. On a procurement spreadsheet, First Solar means Series 6 and Series 7 modules, not a planet.

2. What is the first solar cell, and is it a First Solar product?

Most people searching for the phrase "first solar cell" want the first practical photovoltaic device. That was the silicon solar cell demonstrated at Bell Labs in 1954, with an efficiency around six percent. First Solar did not make it. The company was founded in 1999 and builds modern CdTe thin-film modules for large power plants. Why does the difference matter? Because a first solar cell is history, while a First Solar module must survive a lender's technical review. I buy the one that can hold up a 25-year financial model.

3. What makes First Solar competitive on total cost?

I compare total 25-year cost, not invoice price per watt. First Solar Series 6 Plus modules carry a nameplate around 460W in many publicly listed specs, but the line I watch is the annual degradation warranty. A warranted degradation rate below 0.5% per year improves the energy produced in later years, and later-year energy is what keeps debt ratios healthy. I will not claim thin-film beats crystalline silicon everywhere. In one very hot utility-scale site, the CdTe modules won the LCOE model because of thermal performance and degradation. On the next site, the answer could be different.

4. What should I do with quotes about wind turbines?

There are two kinds of quotes about wind turbines. The first kind is the inspirational line used at the start of a climate presentation. The second kind is the formal quotation a vendor sends after a request for proposal. I can only put the second kind in a financial model. When you ask for quotes about wind turbines, ask the bidder to break out turbine supply, tower, transport, installation, warranty, spare parts, and O&M escalation. Here is something vendors usually do not put on the cover page: the first quote is rarely the complete quote. We normalize every offer before it reaches the investment committee.

5. How much does it cost to buy a wind turbine?

Public cost survey data from U.S. Department of Energy reporting suggests recent land-based wind installed costs of roughly $1,300 to $2,300 per kilowatt, depending on region, turbine size, and site complexity. For a 6 MW turbine, that means roughly $8 million to $14 million for the installed power plant. The turbine and tower supply line alone is typically less; some RFPs we benchmarked show $4-$7 million for a 5-6 MW turbine and tower. The full project cost is the number that should drive the decision. A cheap turbine on a weak wind site is more expensive than a capable turbine on a strong wind site.

6. Is China largest wind turbine a useful benchmark?

China largest wind turbine records change often. As of the records I last verified, CSSC Haizhuang's 18 MW H260-18MW offshore turbine is a strong proof point that large-scale manufacturing is moving fast. I still would not anchor a procurement decision to it. An 18 MW machine requires specialized installation vessels, a very heavy foundation, and a grid connection large enough to absorb it. When someone asks about China largest wind turbine, I treat it as a supply-chain signal, not a specification. The same is true for module gigawatt announcements: the question is whether it lowers project-specific LCOE.

7. First Solar or wind turbines: which is the right choice?

Neither technology is better in the abstract. The efficient answer depends on the site radiation, wind resource, interconnection, local content rules, and the real terms of the 25-year warranty. First Solar's public backlog sits above 66 GW, which tells me lenders accept the bankability story for its CdTe modules. Wind has decades of project finance history behind it as well. I compare both side by side, normalize every offer to a $/MWh levelized cost, and choose the project with the best risk-adjusted return. Why does the comparison process matter? Because the developer who can complete it quickly and honestly has a real cost advantage.

My bottom line from the cost-controller side: do not let search confusion decide a capital decision. The first planet in solar system is Mercury, the first solar cell came from 1954, wind turbine quotes need line items, and the China largest wind turbine is impressive context. The hard work is still the same: total cost over 20 to 25 years, not the name on the data sheet.
