Solar

Sector thesis

Solar is the business of converting sunlight into electricity using panels, inverters, and mounting systems. It's part of the broader clean energy shift, but solar specifically has become the fastest-growing source of new electricity generation globally because the cost per watt has fallen 90% over the past 15 years. That trend is structural: governments are mandating renewable energy targets, electricity grids need decarbonization, and companies face pressure to cut carbon footprints. Solar isn't a speculative bet anymore—it's competing on pure economics. Within solar, three sub-sectors matter most. First, panel manufacturing: companies that make the silicon wafers and cells that actually capture sunlight. Second, installation and balance-of-system: the racking, wiring, inverters, and labor that turn panels into working systems. Third, project development: companies that own and operate solar farms or rooftop systems, collecting revenue from selling electricity over 20+ years. The biggest risk is overcapacity. When margins look good, new factories get built, supply floods the market, and prices crash. This cycle has happened repeatedly. A second risk is policy whiplash: subsidies and tax credits drive demand, but they can change with new administrations. Third, supply chain concentration—much of the world's panel production is in one region, creating geopolitical and logistical vulnerability. For a retail portfolio, solar isn't a single bet. You could own a diversified clean-energy ETF to get exposure without picking individual winners. Or you could buy a large, integrated player with multiple revenue streams (manufacturing plus installation plus projects). Watch for: gross margins (the profit left after making or installing a panel), order backlogs (signals future revenue), and policy announcements. Solar is real infrastructure, not hype—but it's also cyclical and competitive.
