It is true that the solar industry is heading into a partial solar eclipse—as political uncertainty casts a shadow over its growth, but this isn’t a new phenomenon. Over the past two decades, we've seen solar industry navigating numerous political ups and downs such as 2016 ITC sunset threat, CA NEM 3.0, and 2022 AD CVD tariff threat: from shifting subsidies to trade tariffs. The proposed legislation could potentially slash demand by 50% or more, given the residential market’s price sensitivity, though history shows the industry often rebounds from such setbacks. Despite the challenge, several factors provide a silver lining. Technological advancements continue to bolster solar’s appeal, with PV panels and inverters becoming more efficient and affordable, alongside reductions in soft costs like permitting and labor. Fallen costs of battery energy storage and combining PV with BESS give more reliable, flexible, and resilience solution than a standalone PV. Consumer demand remains robust, where solar often achieves cost parity with fossil fuels—though a 30% price hike from the credit’s loss would be a major headwind. If somehow the bill passes, I expect state-level incentives to emerge, particularly in Democrat states to offset some of the federal level clawback. Additionally, rising energy prices due to increasing energy demand could make the higher upfront cost of solar installations more palatable over time, especially if electricity rates continue to climb. Keep in mind this bill still needs Senate approval, and there’s likely to be significant pushback from key Republican states like Texas, Indiana, and the Carolinas, where billions are being invested in solar factories, supporting thousands of jobs. Trump’s effort to dismantle the IRA tax credit may face resistance from these red states prioritizing economic interests. For now, I’d hold off on acquiring residential solar installation companies unless there is a fire sale opportunity. Instead, keep a close eye on the market and target installation firms that have diversified into battery energy storage systems and have a strong foothold in the commercial and industrial (C&I) sector, rather than depending solely on residential sales, as they’ll be better equipped to navigate this uncertainty. (You didn't specify what type of solar company you were after, but based on the post on this website, I'm assuming it is solar installation/service companies in the residential sector.)

I'm going to chime in from left field here, specifically regarding manufacturing, as the sourcing and cost of panels is one of the primary drivers of the total cost of installation, and solar manufacturing in developing countries has been a "passion project" of mine for some years. In short, even with China historically trying to gain control of the world market, it's actually possible to manufacture profitably here in America, the biggest risk is... the risk! I see it going a few different ways, in approximate order of probability: 1 - China evades tariffs by passing things through e.g. Vietnam NB: not easy to detect, bit of a "whack-a-mole" scenario when it comes to tariffs, and may lead to product-based tariffs vs country-based 2 - other countries with established solar manufacturing base (e.g. India) will increase trade NB: does not change the stated goal of increased American manufacturing, so may also lead to product-based tariffs 3 - existing American solar manufacturers will increase output NB: tough to gauge, one of the challenges facing American manufacturers over the last decade or so is a lot of them jumped in during the early years of the solar "gold rush" and got stuck with rather high equipment financing due to buying high-end European assembly lines (Ecoprogetti and similar) and have been barely surviving since China ramped up. In most cases they cannot significantly increase output without either adding more (expensive) modules to their existing lines, or spinning up new lines (individual production modules may be cheaper but overall capital expense for an entire line is still high) 4 - new American manufacturers will appear NB: same as #3, it's hard to justify a large capital expense when many of the current administration's more radical changes may be rolled back by the next administration. In summary, while there may be a few new players on the manufacturing side, (e.g. using novel approaches to manufacturing, exploiting tariff loopholes etc), I see a definite lull for the next few years for retail installers, along with quite a bit of consolidation in the industry.
