Climate and Clean Energy — What's Going On (April 2026)
The Short Version
You'll see headlines saying this market is worth "$880 billion, growing to $2.8 trillion." That number is almost meaningless for a solo software founder, and here's why: most of that money is spent on physical stuff — solar panels, wind turbines, power lines, and batteries — not software. In 2025, investors put $40.5 billion into climate-tech companies, and only about 13% of that ($5.3 billion) went to software companies. The other 87% went to hardware and construction-style projects. That $5.3 billion a year is still a real and growing amount of money — just a much smaller, more honest number than the headline. The part of this market that a solo founder could realistically sell software into is more like $5–15 billion globally today, split across four or five very different customer groups.
How Big Is This, Really?
The whole market (hardware + services + software): about $880 billion in 2024, expected to grow to about $2.8 trillion by 2030 (growing about 24% a year) Just the software part (our best estimate): about $8–15 billion today, and it's growing faster than the headline number Money invested in climate-tech startups in 2025: $40.5 billion total; only about $5.3 billion of that went to software companies (source: Sightline Climate)

1. Who Actually Buys This Software?
| Group | Who they are | How many are out there (US) | Can they say yes to a purchase without asking a boss? | Can a solo founder sell to them? |
|---|---|---|---|---|
| Solar installers (homes and small businesses) | Small contractor teams, 2–30 people | 15,000+ active companies | Yes, at $100–500/month | YES |
| Home energy auditors | Solo workers and small firms | About 5,000 certified | Yes, at $50–200/month | YES |
| Sustainability managers at mid-size companies | Employees at medium-sized businesses | About 50,000 US companies | Sort of, at $300–1,000/month | MAYBE |
| Big-company carbon accounting | Requires sign-off from executives | The 5,000 biggest US companies | No — needs $15,000+/year approval | NO |
| Small EV charging station operators | Property managers and small businesses | About 5,000 independent US operators | Yes, at $100–500/month | YES |
| Homeowners with solar panels | Regular homeowners | About 6 million US homes | Yes, at $10–30/month, but hard to reach and convince | HARD |
| Utility and power-grid companies | Big regulated companies | About 3,000 US utilities | No — needs $100,000+/year approval | NO |
| Large-scale solar builders | Big construction companies | Fewer than 500 major players | No — needs $50,000+/year approval | NO |
The takeaway: the customers a solo founder can actually reach are solar installers, home energy auditors, and small EV charging operators. Selling to sustainability managers is possible but harder, and that space already has a lot of competition.
2. Where Is the Growth Actually Coming From?
Most of the growth in that huge $880 billion number comes from:
- Solar hardware: $450 billion spent on solar equipment in 2025 alone (source: IEA) — that's panels, inverters, mounting hardware, and the labor to install it, not software
- Battery storage: passed $65 billion in 2025
- Power grid equipment: about $400 billion a year, mostly physical power lines and equipment
The software part of the market is growing because of different reasons:
- New rules in Europe (CSRD) and some US states (California) requiring companies to report their environmental impact
- More solar installations creating more day-to-day operations work for small solar companies to manage
- More EV chargers being built, which need software to manage them
- Big companies promising to go green, which creates demand for tools that track and report emissions
Being honest about it: for a solo software founder, the real growth is in tools for the people actually doing the work — the contractors, small businesses, and mid-size companies installing or managing clean energy. That part of the market is growing 15–25% a year, not the flashier 24% headline number.

3. How Big Is Each Specific Piece of Software?
Software for designing solar installations
- Solar design software: $1.31 billion in 2024, growing to $4.08 billion by 2033 (about 13.5% a year)
- Solar rooftop design software specifically: $156 million in 2024, growing to $326 million by 2033 (about 8.5% a year)
- All photovoltaic (solar panel) software combined: $967 million in 2024, growing to $2.25 billion by 2034 (about 8.9% a year)
- Note: these numbers don't include the separate tools installers use for managing customers and projects, which is a real, related market too

Software for tracking a company's carbon footprint
Different research firms give wildly different numbers here — a sign that some of these reports are exaggerated to sell to investors. Take these as rough signals, not exact facts:
- Fortune Business Insights: $27.5 billion in 2026, growing to $136 billion by 2034 (about 22% a year)
- Grand View Research: $13 billion in 2026, growing to $68 billion by 2033
- SNS Insider: predicts $191 billion by 2035 — this one is almost certainly too high
- MarkNtel Advisors: predicts about 25.73% growth per year from 2026–2032
What we can say for sure: this market is growing fast, and it's dominated by tools built for big companies (Watershop, Persefoni, Workiva). Small and medium-sized businesses are underserved.

Software for managing building energy use
- Most trustworthy estimates: $46–60 billion in 2025–2026, growing to $105 billion by 2032 (about 9–12% a year)
- This part of the market mostly sells to big companies — building owners, factories, and utilities. Sales take a long time to close.
Sources: Energy Management Systems Market — Grand View Research · Energy Management Systems — Mordor Intelligence · Energy Management Software Market — Fortune Business Insights
Software for managing EV charging stations
- $1.35 billion in 2025, growing to $1.68 billion in 2026, and $6.81 billion by 2032 (about 26% a year)
- This one is smaller but growing fast, and easier for a solo founder to break into. Small charging station owners aren't well served by the big enterprise tools.

4. Who's Already Selling to Each Group
Solar design and proposal software
| Company | Money raised | What it costs | How many use it | What's missing |
|---|---|---|---|---|
| Aurora Solar | $520M raised, worth $4B (2022), $170M in sales (2023) | $159–$259 per person/month, plus a $15K/year minimum for big accounts | 7,000+ solar companies | Doesn't auto-generate wiring diagrams; expensive for small teams; confusing pricing |
| OpenSolar | Backed by investors, makes money through financing and hardware partnerships | Free forever for installers | 28,000+ users in 185 countries | Not a way to make money that a solo founder could copy; some engineering features missing |
| HelioScope | Owned by a bigger company (Heliogen) | $2,799–$6,399/year | Not public | Built for big commercial projects, overkill for home installs |
| Solargraf | Owned by Accela | $2,799–$12,999/year | Not public | Customer reviews call the shading calculations "absolute garbage"; accuracy problems |
| SurgePV | Small startup | Not public | Not public | Good at auto-generating wiring diagrams; gaining popularity with commercial installers |
What installers complain about:
- Aurora doesn't automatically create wiring diagrams, so bigger installers also have to pay for AutoCAD (about $2,000/year) on top
- Getting permits and getting connected to the power grid is the #1 headache — 33% of solar companies named it their biggest challenge in a 2025 survey
- Aurora charges per-project credits that add up fast — a small company doing 100 projects a month can spend $15,000+/year just on that
- A free government tool (SolarAPP+) now instantly approves permits in over 520 places, which is shrinking the opportunity to sell separate permitting software

Software solar companies use to manage customers and projects
| Company | Money raised | What it costs | Who uses it | What's missing |
|---|---|---|---|---|
| Scoop Solar | Backed by investors | Not public | Not public | Built more for big operations |
| Sunbase Data | Not public | About $100–300 per person/month (estimated) | Not public | Mixed reviews; some users say it didn't work as promised |
| JobNimbus | Backed by investors | $25–60 per person/month | Not public | Started as roofing software, adapted for solar; fairly generic |
| Pipe Solar | Small startup | Not public | Not public | Focused on proposals and project tracking |
| OpenSolar's built-in CRM | See above | Free | 28,000+ | Not as full-featured as dedicated tools — but it's free |
The gap: small solar companies (under 10 people) often use Aurora for design, a generic tool like HubSpot for customer tracking, and spreadsheets for everything else. They want one tool built just for them that doesn't cost $200 per person every month.

Software for tracking a company's carbon footprint
| Company | Money raised | What it costs | Who uses it | What's missing |
|---|---|---|---|---|
| Watershed | $170M total (including $100M at a $1.8B valuation) | $15,000–$50,000+/year | Big companies like BlackRock, Airbnb, Stripe | Built only for big companies; no cheaper option |
| Persefoni | $101M raised | Custom pricing; starts around $500/month for smaller accounts | Large companies and banks | Complicated to set up; built for big-company buyers |
| Greenly | $78.6M total | About €3,800–€7,800/year ($3,000–5,000) | 3,500 customers | Aimed at smaller businesses, but still too pricey for a solo founder or early-stage company |
| Workiva | Public company | Custom, enterprise-only | Large public companies | Built only for big companies with financial reporting needs |
| Aclymate | Appears to be a small, self-funded company | $120/year for companies with 1–10 employees | Not public | Cheapest option by far, but has fewer features |
| Microsoft Sustainability Manager | Part of Microsoft's ecosystem | $4,000–$12,000/month | Big companies | Extremely expensive; enterprise-only |
| Salesforce Net Zero Cloud | Part of Salesforce | $48,000–$210,000/year | Big companies | Same story — enterprise-only |
The gap: companies with 10–200 employees are being asked by their bigger customers or investors to report their emissions, but can't afford Greenly's $3,800/year or Watershed's $15,000+/year. Most of them are just doing it by hand in spreadsheets, or paying a consultant. Rules requiring this kind of reporting are still active in Europe (for companies over 1,000 employees) and in California, and big companies keep pushing their smaller suppliers to provide this data.

Software for home energy audits
| Company | Money raised | What it costs | Who uses it | What's missing |
|---|---|---|---|---|
| Snugg Pro | Likely self-funded | Not public | 50+ US home-performance programs | Built for government programs, not contractors first |
| EDS Auditor | Small software company | $24/month per user | Not public | Good price, but outdated design |
| Elite Software AuditW | Older desktop software | One-time purchase | Not public | Old technology, doesn't work on phones |
| MINT (Hancock Software) | Small company | Not public | Not public | A mobile tool for a small niche |
The gap: heating/cooling contractors and home energy auditors need a tool that makes a nice report for the customer, connects to government rebate programs, and works with the scheduling software they already use (like ServiceTitan or Housecall Pro). No current tool does all three well.

Software for small EV charging station operators
| Company | Money raised | What it costs | Who uses it | What's missing |
|---|---|---|---|---|
| ChargePoint | Public company | Hardware plus a subscription, now also charging $0.25–$0.49 per charging session | 44,694+ US charging stations | Confusing fees; recent fee increases have upset customers; built for big operators |
| Blink | Public company | They own the hardware and take a cut of revenue | Large network | Not built for operators who own their own equipment |
| EV Connect | Privately owned | Pricing not public | Small businesses and city governments | Works well for small/medium operators, but pricing isn't transparent |
| ChargeLab | Backed by investors | Built for bigger operators and developers | Not public | More of an enterprise product |
What small operators complain about:
- ChargePoint's new 2026 fees add $0.25–$0.99 per charging session on top of what the operator already charges, which upsets EV drivers and makes the property look bad
- Many small operators still reconcile their billing by hand
- Checking that chargers are actually working, across multiple locations, is hard without paying for an enterprise plan
- Managing how much power is used at once (so you don't get hit with extra utility fees) is complicated to set up

5. What People In Each Group Are Actually Complaining About
Solar installers
- Getting permits and grid approval is the #1 complaint (33% of solar companies said so in a 2025 survey)
- Aurora Solar's pay-per-project pricing adds up fast — small installers paying as they go can easily hit $250–400/month
- No single tool handles proposals, permits, project tracking, and customer messages together — most companies juggle 3–5 different tools
- People complain that Solargraf's shading and production estimates are inaccurate, forcing them to double-check in other tools
- Bigger commercial installers still pay for both Aurora and AutoCAD because no affordable tool auto-generates wiring diagrams
- How long permits take varies wildly by location — anywhere from 2 days to 3 months

Home energy consultants and auditors
- Most still use spreadsheets or old desktop software
- Figuring out which government tax credits a homeowner actually qualifies for is complicated, and no simple tool explains it clearly
- Making a professional-looking audit report takes a long time with the old tools available
- Snugg Pro is built around government program paperwork, not around what contractors actually want, which is something that impresses the customer
Sustainability managers at mid-size companies
- The big tools (Watershed at $15,000+, Workiva at custom pricing, Salesforce at $48,000+) are too expensive
- Greenly, at $3,800/year, is the cheapest credible option — but it still needs someone dedicated to running it
- Many mid-size companies are stuck using spreadsheets because nothing exists at the $500–1,500/year price point that makes financial sense for them
- Companies often end up buying two different tools because the ones that are good at tracking emissions are weak at generating reports, and vice versa
- US federal rules requiring this reporting are on pause right now, which has reduced urgency for American companies — but companies in Europe and California, or those supplying to companies in Europe and California, still need it
- Collecting emissions data from suppliers (not just your own company) is described as the hardest part of this whole job, across the board
EV charging station operators
- ChargePoint's 2026 fee changes made a lot of operators angry — they feel like pricing was changed on them without warning
- Checking that chargers are working usually has to be done by hand, or requires an expensive enterprise plan
- Billing disagreements are common, and small operators with 5–20 chargers usually fix them by hand
- Managing power usage to avoid extra utility fees isn't something regular, affordable tools can do yet
Homeowners with solar panels
- Monitoring apps (SolarEdge, Enphase Enlighten) only work with one brand of equipment — there's no single app that shows everything
- There's no good tool to check whether your solar panels are actually saving you as much money as the installer promised
- Battery performance tracking is separate from tracking how much power you're sending back to the grid
- It's hard and expensive for a solo founder to reach individual homeowners as customers — they don't go looking for this kind of software on their own
6. Is All This Growth Actually Reachable for a Solo Founder?
Short answer: mostly no, for the big picture. But three specific pieces of it are genuinely real opportunities.
| The Risk | What's Actually True |
|---|---|
| Hardware vs. software | About 87% of climate-tech investment money goes to hardware; software is only about $5.3 billion a year |
| Big installations need salespeople | Solar and wind projects bigger than 1 megawatt require government approvals and engineering studies — that's a whole sales team's job, not a solo founder's |
| "Deep tech" is a trap | Things like nuclear fusion, hydrogen fuel, and advanced geothermal power all need government certifications, approvals, and hardware partnerships — there's no solo path here |
| Rules keep changing | A US federal climate rule is currently paused. Europe's rule now only applies to companies with 1,000+ employees (as of a change in December 2025). This makes the US market less urgent right now |
| "Carbon credit marketplace" is a trap | This is a regulated space that needs real legal setup and official certification — don't try this alone |
| Certifications add real cost | Home energy auditors need official certification (HERS, BPI). Solar installers often need NABCEP certification. EV charging hardware needs official compatibility testing (OCPP) and safety certification (UL). Each one adds cost and complexity |
What's actually real and reachable:
- Software that helps solar installers run their day-to-day business (tracking customers, projects, and messages) — genuine pain, and real budget to spend on it
- Report-making and rebate-calculating tools for home energy auditors and contractors — a small market, but almost nobody has built proper software for it yet
- Carbon-footprint tracking for the 10–200 employee company that just needs to answer one big customer's yearly questionnaire — the pain is sharp, and there's no affordable tool for it yet
- Billing and uptime-tracking tools for people who own 5–50 EV chargers — real pain, but you'll need to learn the technical standard (OCPP) that charging stations use to talk to software
7. Has Anyone Small Actually Made Money Doing This?
There's almost no public information about small, self-funded climate or energy software companies. Here's what we could find:
- Aclymate — Appears to be a small, self-funded carbon-tracking tool for small businesses, starting at $120/year. We couldn't find public revenue numbers, but it's clearly a real company with real customers. The fact that this price point exists at all proves people will pay for a cheaper option.
- EDS Tech / EDS Auditor — A small software company charging $24/month per user, serving heating and cooling contractors. Looks like a small, steady business, not a fast-growing startup — which proves people in this space will pay for a good tool.
- SolarAPP+ — Funded by the government, not a solo project, but it proves that getting solar permits is a real, widely-felt pain point.
- Snugg Pro — A small company serving government energy programs. Not a solo founder story, but a small team making it work.
There's almost no one posting about climate or energy software on sites like Indie Hackers with real revenue numbers. That could mean nobody's building here — or that people have tried and it didn't work out. Since similar tools for other trade industries (construction, roofing) have worked, it's more likely that this is simply an open opportunity nobody's claimed yet.
How companies like this typically find customers, based on similar trade industries (heating/cooling, roofing, solar):
- YouTube channels and sponsorships in trade publications (Solar Builder, PV Magazine)
- Industry trade shows (Solar Power International, the RE+ conference)
- Facebook groups for solar contractors
- Communities built around the NABCEP solar certification
- Reaching out directly to solar installer associations

8. Parts of This Market to Avoid Building Alone
Some parts of this industry legally require official certifications or government relationships that make them a bad fit for a solo founder:
| This part of the market... | ...needs this to operate legally |
|---|---|
| Carbon credit marketplaces | Official certification (VCS, Gold Standard) and heavy regulation |
| Official home energy rating software | Requires the founder or team to be a certified HERS rater |
| Software that connects to the power grid | Needs regulatory approval and direct utility company partnerships |
| Managing power for whole neighborhoods ("virtual power plants") | Needs approval from federal and regional power regulators |
| EV charger hardware management | Needs to follow the OCPP technical standard and UL safety certification |
| Official building energy code compliance | Requires IECC certification and relationships with local building inspectors |
9. What a Solo Founder Could Actually Build
Option 1: An all-in-one operations tool for solar installers (BEST BET)
The idea: a simple, affordable ($49–$149/month) tool that tracks customers, project status, and scheduling for small home-solar companies (fewer than 10 employees). Not a design tool — Aurora and OpenSolar already do that well. The missing piece is the day-to-day operations: tracking leads, scheduling installs, tracking permit status, messaging customers, and storing documents.
Why now:
- There are 15,000+ small solar companies in the US, and most of them juggle 3–5 different disconnected tools
- Aurora is focused on design, Scoop is built for big companies, and nobody owns the "small solar company operations" space
- Installers already pay $100–300/month for similar software (they're already paying that much for Aurora), so the willingness to pay exists
- More homes are getting solar every year (rooftop solar makes up 42% of all new solar installed worldwide, per the IEA), which means more small installer companies need this
What makes this different: JobNimbus is a generic tool, not built for solar. Aurora connects with other software but doesn't handle daily operations. Scoop is built for big companies. OpenSolar is free, but limited.
How to find customers: Facebook groups for solar contractors, the NABCEP certification community, YouTube — these are people who search online for solutions to their problems.
The risk: Aurora Solar is already starting to build some of these features itself, and OpenSolar keeps adding features for free. It's a race against companies that already have a head start.
Option 2: A carbon-footprint reporting tool built for one purpose (FOCUSED BET)
The idea: a $29–$99/month tool that helps a 20–200 person company answer the one yearly emissions questionnaire that a big customer (like Walmart, Target, or Apple) sends them. Not a full carbon-tracking platform — just enough to answer the basic questions, generate a professional-looking report, and not embarrass the company.
Why now:
- Big companies are increasingly demanding this data from their smaller suppliers, and those suppliers have no good tool to respond with
- Watershed ($15,000/year), Greenly ($3,800/year), and Persefoni (enterprise-only) are all way more than a company needs just to answer one form
- Aclymate charges $120/year but doesn't have enough features — there's a big, empty gap between $120/year and $3,800/year
- A California law (SB 253) requires large companies to report their supply chain's emissions, which is pushing this requirement down to smaller suppliers
What makes this different: nobody has built a tool specifically for "answering my customer's emissions questionnaire." People could buy it themselves at $29–$99/month without needing approval from a boss, and the pain is urgent — there's usually a real deadline attached to the customer's request.
How to find customers: LinkedIn (sustainability coordinators are an active audience there), people searching Google for "how to answer a carbon emissions questionnaire," and content marketing around supply-chain emissions reporting.
The risk: bigger companies could start offering a cheaper tier to compete. US rules could stay paused, reducing urgency. Companies based in Europe might prefer a European-based tool instead.
Option 3: A tax-credit and rebate calculator for contractors (SMALLEST BET, FASTEST TO BUILD)
The idea: a tool that heating/cooling contractors and home energy auditors use during a sales visit to calculate exactly how much a homeowner would get back in government tax credits and utility rebates for a heat pump, insulation, or solar upgrade. It spits out a customer-facing PDF that says "you qualify for $X back." Contractors would pay $29–$79/month and use it on every single sales call.
Why now:
- Federal tax credits (from the Inflation Reduction Act) are complicated, change based on income, and vary by state and utility company
- No simple tool exists for contractors to explain this to a customer — they either get it wrong or don't mention it at all
- Contractors are increasingly asked "what do I actually get back?" and don't have a good answer ready
- The existing tools for auditors (Snugg Pro, EDS Auditor) focus on technical calculations, not on explaining rebates to the customer
How to find customers: heating/cooling contractor associations (ACCA), the Building Performance Institute (BPI), RESNET online forums, and the Housecall Pro app marketplace.
The risk: these tax credits could be reduced or repealed by lawmakers (they hadn't been, as of April 2026, but it's a real possibility). A site called EnergySage already does some of this for regular consumers. The market itself is small — maybe 10,000–20,000 contractors who do this kind of energy-upgrade work.
10. So Is the $880 Billion Number Real or Not?
| Question | Answer |
|---|---|
| Is the 24%-a-year growth real? | Yes, for hardware. For software, growth is more like 12–25% depending on which piece you're looking at |
| How much of the market is actually software? | About $8–15 billion today, possibly growing to around $50 billion by 2030 |
| How much of that goes through a big, slow sales process? | About 75–80% of the software spending is big-company purchases (Workiva, Salesforce, Microsoft) |
| What share of climate-tech investment money goes to software? | About 13% ($5.3 billion out of $40.5 billion in 2025) |
| Is there one big company a solo founder could realistically compete with and beat? | Not really — Aurora Solar is the closest example (expensive, with some gaps), but it's also well-funded. The tools for solar company operations have real, documented complaints |
| Could a solo founder realistically make $5,000/month within a year? | Yes — most likely in solar operations software or the supplier carbon-reporting tool. Both have customers who can buy without asking a boss, feel real pain right now, and are willing to pay $50–150/month |
| What should a solo founder avoid? | Hardware, power-grid software, carbon credit marketplaces, tools sold to utility companies, and apps aimed at individual homeowners (too hard and expensive to reach one at a time) |
