Tesla Inc. (TSLA) - Solar Manufacturing Expansion and Grid Decarbonization Thesis Signal Undervalued Growth Lever - Annual Report

Live News

On Monday, April 27, 2026, newly surfaced comments from Tesla CEO Elon Musk at the World Economic Forum in Davos reaffirmed his long-held thesis that just 10,000 square miles (100 miles by 100 miles) of solar panels, paired with 1 square mile of utility-scale battery storage, is sufficient to power the entire U.S. electricity grid. Musk noted that widespread deployment is currently held back by high U.S. import tariffs on Chinese-manufactured solar panels, which artificially inflate deployment c Tesla Inc.

Key Highlights

The latest comments and strategic announcements carry four core takeaways for investors. First, Musk’s 2017 solar grid thesis is now economically viable: solar panel costs have dropped 72% since 2017, while lithium-ion storage costs have fallen 84% over the same period, per BloombergNEF data, materially improving the project economics of large-scale solar deployments. Second, policy headwinds create a near-term gap for domestic manufacturing: current U.S. tariffs on imported solar panels raise d Tesla Inc.

Expert Insights

For Tesla investors, the solar manufacturing expansion represents a significantly underpriced growth lever that is largely unaccounted for in consensus sell-side estimates, which currently allocate just 7% of projected 2030 revenue to Tesla’s energy generation and storage segment, with 89% of valuation weighted to EV and full-self driving software revenue. At full 100GW annual production, we estimate Tesla’s solar segment could generate $14-$20B in incremental annual revenue, assuming an average selling price of $0.14-$0.20 per watt for utility-scale panels, paired with high-margin storage and installation services that carry gross margins 10-15 percentage points higher than Tesla’s core EV segment. Tesla already holds a 41% share of the U.S. utility-scale battery storage market via its Megapack product, creating a powerful cross-sell opportunity for integrated solar-storage solutions for utilities, corporate data center operators, and government entities seeking 24/7 zero-carbon power to meet ESG and reliability targets. That said, investors should weigh material execution and policy risks: the 3-year manufacturing ramp timeline is aggressive, and Tesla will face competition from existing domestic solar manufacturers including First Solar, as well as potential policy shifts that could reduce import tariffs and erode the competitive advantage of domestic production. Additionally, while Musk’s 100x100 mile solar footprint claim is technically accurate, real-world deployment will require distributed solar infrastructure across multiple states to mitigate weather and transmission risks, which will require expanded installation capacity beyond Tesla’s current network. Overall, however, the strategic move aligns Tesla’s product portfolio with long-term macro trends: AI-driven electricity demand growth, global decarbonization targets, and U.S. industrial policy prioritizing domestic supply chain resilience. Consensus 2028 EPS estimates of $19.20 per share do not include any contribution from the planned solar manufacturing capacity, implying 15-22% upside to earnings if the ramp meets management targets, supporting our bullish outlook on the stock’s long-term value.
