Now cheaper than fossil fuels on a global scale, the economics of solar is propelling clean energy in a way that politics or climate claims never could.
For decades, the solar sector has been fighting the same valuation battle that is plaguing the housing sector: first cost was regularly considered over full cost. Solar has won the full cost argument for years, but this summer it reached an important milestone—it is now cheaper upfront to create new solar power on a MWh basis than fossil fuel power, collapsing the first cost objection.
Solar PV installed costs have fallen 87% since 2010. Battery storage costs have fallen 93% over the same period, according to the International Renewable Energy Agency (IRENA).
A decade ago, solar carried roughly a five-to-one capital disadvantage against coal and gas for the same annual electricity delivered. Solar now requires less upfront investment than a coal or gas plant to produce the same amount of power.
New solar + storage installations now average $54 and $82 per MWh in high-irradiance markets (areas that get a lot of sun), compared to upwards of $100 per MWh for new gas plants on a global scale. Those numbers don’t even include the 30% decline in solar costs that is projected by 2030.
And that cost comparison is generous, because it only includes the numbers associated with plant buildouts, not infrastructure costs. But gas needs pipelines, terminals, and storage, and coal needs mines and railways—the full cost of a fossil plant is never the cost of the plant alone.
According to OilPrice, “Solar has reached parity not only in the eventual price of electricity, but in the initial capital required to produce it. Batteries are following the same curve, turning firm clean power from a distant ambition into a competitive option in an expanding number of markets. The transition still needs grids, flexibility and better financing. Solar has not solved every system problem. But fossil power has lost one of its last simple economic defenses: it is no longer necessarily cheaper to build today and pay for tomorrow.”
China: Proof of Scale
At the end of July 2026, China’s installed solar capacity passed coal for the first time, reaching 1,286 GW, or 31.5% of the country’s total generating capacity. In the first half of the year, coal’s share of actual electricity output fell below 50% for the first time in modern Chinese history. Renewables supplied 41.2% of generation; wind and solar together delivered close to a quarter of all power.
As China continues to build solar + storage capacity, bolstering its own national economy, it’s important to note that it’s not all smooth sailing: curtailment remains a problem, projects have slowed under policy changes, and coal is still doing the heavy lifting for grid reliability. However, none of that undermines the milestone, nor does it erase the fact that a country that industrialized on coal now generates more of its capacity from panels than from furnaces—a transition that was made based on economics alone.
U.S. Homeowner Dynamics
Solar’s macro story speaks for itself on a utility, commercial, and industrial scale. But what happens to consumer behavior once price stops being the upfront adoption obstacle?
According to COGNITION Smart Data, when asked what would motivate them to go solar, homeowners reported economic savings for years. In July 2024, 32% cited saving money as their primary motivation. In March 2025, 30%. In July 2026, that number fell to 17%.
Meanwhile, “increasing self-sufficiency” soared from 25% to 23% to 49% in that same timeframe, and it is now the dominant motivation by a factor of nearly three over cost savings.
Increased interest in self-sufficiency in 2026 is striking.
The instinct is to read a declining “save money” number as bad news for solar, but it’s really the opposite. Price stopped being the argument the moment it stopped being the obstacle. Economics became the permission structure, not the motivation, and the motivation that filled the vacuum is security and control.
Additionally, homeowners reporting that they installed solar went from 9% in July 2024 to 47% in July 2026. Battery storage went from 3% to 45%. Between March 2025 and July 2026 alone, smart electrical panels went from 4% to 29%, and demand-side energy management went from 2% to 28%.
Installed solar and battery storage soared in 2026.
When we ask homeowners what they would invest in to convert their homes to all-electric, 57% say battery storage systems and 53% site solar panels (followed by smart electrical panels at 38%, smart thermostats at 36%, and demand-side energy management systems at 33%.)
For the first time since we have been surveying our consumer audience, storage is ahead of generation. That matters because a homeowner buying panels is buying cheaper electricity, but a homeowner buying panels and a battery is buying the ability to not care what the grid does on a scorching Tuesday afternoon in August, or a freezing Thursday evening in January. Or when the wildfire comes, or the superstorm.
COGNITION data also shows that homeowners put backup power, generators, and battery storage second only to upgraded roofing at 38.7% at the top of their resiliency upgrades wish list. When asked what should be standard in every new home, 50.4% named backup power systems, placing it above solar-ready construction at 26.3% and just behind fire-resistant materials at 54.9%.
The Builder Edit
Here’s the part that should make the residential industry uncomfortable. The first-cost defense collapsed in utility-scale solar generation because capital markets were forced to price the whole asset — the plant, the fuel chain, the infrastructure, the thirty-year obligation. Housing has not been forced to do that yet.
We still sell homes on price per square foot—how big a house is and how much it costs today— and then hand over the operating cost, the insurance exposure, the grid dependency, and the retrofit bill at closing. We still treat solar-ready wiring, panel capacity, and storage provisions as upgrades rather than infrastructure, in a market where half of consumers now say backup power should be standard equipment.
And we are still doing it while the underlying economics move against us. A home built today without the electrical capacity for storage, without the roof geometry for panels, without the panel headroom for a heat pump and two EVs, is not a cheaper home. It is a home with a deferred invoice attached, and the first homeowner, will pay it during a retrofit at three times the cost of doing it during initial construction.
That is the definition of cheap upfront, expensive forever.
What Changes Now
For 20 years, the case for building better required an argument. It required convincing someone to accept a higher first cost in exchange for a benefit they would collect later. That was always a hard sell, and honestly, it was a fair objection in a market that never priced the later.
That trade no longer describes reality in generation, and it is eroding fast in construction. Solar and storage are not a premium anymore. They are the cost-competitive path, chosen by the largest energy market in the world for the least sentimental reason there is.
The question for builders is no longer whether the economics work. It is whether we are willing to count them. You cannot reprice what you refuse to count, and the industry has spent decades refusing to count operating cost, resilience value, and grid independence.
Our data says homeowners have stopped waiting for us to do that math. They are buying batteries before panels, ranking backup power above solar, and telling us that what they want from a house is not virtue but autonomy.
Is the industry finally ready to listen?
