Potential upside & downside to trefis price

SunPower Company


  1. North America Residential constitutes 46% of the Trefis price estimate for SunPower's stock.
  2. SunPower Technologies constitute 42% of the Trefis price estimate for SunPower's stock.
  3. North America Commercial constitutes 12% of the Trefis price estimate for SunPower's stock.


Q3 '22 Earnings update

SunPower reported net sales of $476 million in Q3 '22, up strongly from $283 million in Q3 '21. However, rising operating expenses saw the company report just a $12 million operating profit, down from $17 million for the same period last year. Despite this, a $135 million other income helped boost net earnings, driving EPS to $0.80, up from -$0.49 in Q3 '21.


Below are key drivers of SunPower's value that present opportunities for upside or downside to the current Trefis price estimate for SunPower:

SunPower Technologies

  • SunPower Technologies Revenue : SunPower Technologies saw its revenues decline by over 15% since 2018, falling to around $710 million, on account of lower project sales. However, we expect the metric to pick up and grow to roughly $1.9 billion by the end of our review period, driven by higher equipment sales. If the metric rises to over $2.5 billion, exceeding our expectations, there could be a 12% upside to our price estimate. On the other hand, if the metric remains flat at $700 million levels, there could be a downside of 15% to our price estimate.


    SunPower is a manufacturer and distributor of silicon-based solar modules which are used to convert sunlight into electricity. The company produces solar power products for installation on residential and commercial units as well as large-scale, utility-sized projects. SunPower's solar modules have among the highest conversion efficiencies in the industry. The company also develops solar systems including rooftop- and ground-mounted solar systems.
    We are modeling Non-GAAP revenue and cost metrics for SunPower, as U.S. GAAP defers revenues from transactions with the company's joint-venture yieldco, 8Point3 Energy Partners, to the future.


    We estimate that sales of modules and solar systems in the Americas account for most of the company's value. This is partially due to the following factors:

    Increased utility-scale footprint

    Solar cells manufactured by SunPower were historically used for installation on residential and commercial units. However, the company has been steadily increasing its presence in the utility-scale market, constructing some of the world's largest solar farms such as the 579 MW Solar Star project, helping to improve margins. Most of these higher-margin utility project sales are in the Americas.

    Growth opportunity in rooftop solar

    Rooftop solar is expected to be the fastest growing segment in the global power industry. This is a big positive for SunPower, given that the company specializes in higher efficiency solar panels that are well suited for rooftop applications.


    SunPower's Launch Of Next Generation Panels

    SunPower has traditionally led the solar industry in terms of conversion efficiencies, essentially meaning that its panels produce more power for a given size. However, its panels are priced at a significant premium to mass-market panels, limiting its market size to more developed markets and specific applications such as rooftops, where space is a constraint. However, SunPower is currently rolling out its next-generation solar panels with its Next Generation Technology (NGT) which are likely to offer efficiencies of around 23% (roughly in line with its top-end X-Series panels), although costs are likely to be between 30% to 40% lower. SunPower expects these panels to compete head-on in terms of price with the mono-PERC solar panels, which are widely available in the market today while offering higher performance and durability.

    Challenges in the utility-scale business

    Contracting activity in the utility-scale solar business has slowed down and there has been greater competition from smaller players and independent power producers in the project development space, impacting the prices at which PPAs (Purchase Power Agreements) are being signed globally. Additionally, investor IRR expectations for solar projects have trended upwards, putting pressure on the prices that companies such as SunPower can charge for projects.

    Legislature and incentives to aid renewable energy projects

    Governments all across the world have taken measures to encourage the use of solar technology as a way to help them remove their dependence on fossil fuels. For instance, in the United States, at the Federal level, the government offers incentives including an investment tax credit (ITC) of around 30% on the initial cost of a solar system.

    Emerging solar markets will account for bulk of future demand

    China became the worlds largest solar market in 2013, overtaking Germany as the world's largest solar market. Other emerging markets such as Latin America and the Middle East are also becoming important markets for solar power, given a combination of high electricity prices and strong consumption growth.

    Changes to the project financing landscape

    Financing for solar energy projects has been an issue in the past and developers have largely relied on complex tax equity investments or expensive bank debt to fund projects, as they have had difficulty tapping into cheaper sources of capital due to the lack of long-term data on solar power, and also due to the perception of solar as being risky and unproven. However, the decline in solar systems prices of late, as well as the improvements in panel technology, have brought about a greater acceptance of solar power and have made solar assets increasingly attractive. SunPower has been exploring various means to expand funding for its solar systems business. The company has also indicated in the past that it would issue solar asset-backed bonds. These moves could help the company reduce the cost of capital and maximize value from its projects business.
