19 Clean Energy VC Firms in Solar, Wind, Storage
19 VC profiles across solar, wind, and storage with stage, check-size, and founder-fit guidance.
If I were a founder reading this list, I’d focus on three things first: stage, check size, and business model. That one filter cuts through most of the noise fast.
This guide covers 19 clean energy investors across solar, wind, and storage. Some back seed-stage software, some fund Series A/B hardware, and some are built for first commercial deployments or utility-linked deals. A few patterns stand out right away:
- Earliest-stage fit: Clean Energy Ventures, Congruent Ventures, and Energy Transition Ventures
- Deep-tech and larger rounds: Breakthrough Energy Ventures and Energy Impact Partners
- Deployment and project support: Elemental Excelerator, Piva Capital, and 2150
- Software and grid tools: Energize Capital, DCVC, The Westly Group, and Ansa Capital
- Hardware, storage, and industrial systems: Chrysalix, Cycle Capital, VoLo Earth, and Lowercarbon
I’d also keep one thing in mind: subsector alone is not enough. A solar software company and a solar hardware company often fit very different funds, even if both sell into the same market.

19 Clean Energy VC Firms: Stage, Check Size & Best Fit at a Glance
Scaling Climate Tech: How Clean Energy Ventures Backs Game-Changing Startups with Temple Fennell
How This List Is Organized
Each firm sits in the category - solar, wind, or storage - that best matches its main deal pattern. That said, most of these investors don’t stay in a single lane. Firms like Energy Impact Partners and SET Ventures back companies across the energy transition. The label here points to primary activity, not an only focus. [3]
So treat the subsector tag as a starting point, not the full story. Each profile below shows the fund’s actual stage, model, and check-size fit.
These three subsectors don’t work the same way, and that changes what investors want. Solar is more fragmented than wind or storage, so investor interest often comes down to the business model and the customer group a company serves. Wind and storage usually deal with longer permitting and build timelines than software-led clean energy models. On top of that, capital needs can swing from smaller venture checks to large project-finance facilities.
The business model split matters just as much as the subsector label. In each of the three categories, you’ll usually see three company types:
- Hardware: Physical products like solar trackers or battery modules
- Software/Platforms: Digital tools for grid management or access to energy marketplaces
- Project-enabled: EPC services and project-enablement models tied to construction backlogs and recurring O&M revenue
As you read the profiles below, keep those three filters in mind: subsector, business model, and capital needs.
1. Energy Transition Ventures
Energy Transition Ventures (ETV) focuses on early-stage companies across the energy transition. So when you pitch them, traction tends to matter more than a fixed check size.
Typical Check Size
ETV does not publish a standard check size in public materials.
Stage Focus
ETV backs early-stage companies, which means pilots and traction carry a lot of weight. In plain English: they want to see signs that the market is responding, not just a strong deck and big forecasts.
Portfolio Themes
ETV leans toward energy-transition companies that can show commercial traction and a clear path to scale.
Founder Outreach Fit
Lead with pilot results, traction, and unit economics. Put proof up front. If incentives play a role in the business, show that the model still works without them.
2. Clean Energy Ventures
Compared with ETV, Clean Energy Ventures (CEV) has a tighter early-stage focus. The firm leans into Seed and Series A and backs climate tech companies that can drive large-scale emissions cuts.
Typical Check Size
CEV does not share a public standard check size.
Stage Focus
CEV focuses on Seed and Series A.
Portfolio Themes
The firm invests across the energy transition, with clear fit for startups tied to clean energy, electrification, and emissions reduction.
Founder Outreach Fit
Before reaching out, founders should be ready to show measurable emissions impact. If you're building in solar, wind, or storage, that means spelling out the impact in plain terms and tying it to early traction.
So who fits best here? Founders with early proof and measurable climate impact. The bar is pretty straightforward: early proof, clear impact, and a clean energy use case.
3. Congruent Ventures
Congruent Ventures invests in early-stage climate startups across North America, with a strong lean toward solar and a selective focus on storage. It also has one of the largest early-stage climate portfolios in the space. For this list, the firm lines up best with solar, while storage sits close behind. That makes Congruent a good match for founders who need early funding and want a climate-focused network around them.
Typical Check Size
There’s no public standard check size.
Stage Focus
Congruent invests from formation capital, including pre-seed and seed, through Series A [3].
Portfolio Themes
Its clean energy portfolio is strongest in solar and storage. One example is Form Energy, a long-duration storage company [4]. For founders, the bar is pretty clear: you need to show climate impact and venture-scale upside early.
Founder Outreach Fit
Congruent looks for companies that can define a category [3] and pair venture-scale returns with measurable environmental impact. The firm also works closely with founders as they scale [3]. Its geographic focus is North America.
4. Breakthrough Energy Ventures
BEV sits at the deep-tech, larger-check end of clean energy venture capital. Breakthrough Energy Ventures (BEV) has built a portfolio of 83+ companies and has made at least 23 solar investments [3][5].
Typical Check Size
BEV doesn’t publish a set check size. Its recent deals show a pretty broad range, from a $10 million Seed round in Barocal to a $550 million Series C for Antora Energy [5].
Stage Focus
BEV invests across the full startup path, from Seed through Series D [5]. It also runs a Fellows Program aimed at very early-stage technical ideas [5].
Portfolio Themes
You can see that approach in how BEV groups its portfolio. The firm invests around five Grand Challenges: Electricity, Manufacturing, Agriculture, Transportation, and Buildings [3].
Within clean energy, BEV backs companies working on:
Representative portfolio companies include Form Energy, Antora Energy, and Planted Solar [4][5].
Founder Outreach Fit
BEV tends to back deep-tech, hardware-heavy companies, often including university spin-outs [5]. That means founders usually need strong technical proof and a clear path to commercialization. That matters even more in long-cycle categories like fusion and multi-day storage, where the science may be strong but the road to market is longer and more demanding [5][4].
5. Elemental Excelerator
Elemental Excelerator isn't a standard VC fund, but it still earns a spot on this list. Why? Because it helps founders get past the pilot stage and into commercial deployment.
It's a nonprofit climate tech accelerator, not a fund built around plain equity checks. That makes it a strong fit for founders who need help getting projects deployed in the field, not just more capital on the cap table.
Typical Check Size
Elemental Excelerator provides non-dilutive funding for first-of-a-kind deployments.
Stage Focus
It backs companies that are ready for their first two commercial deployments.
Portfolio Themes
Its focus spans:
- Solar
- Storage
- Grid
- Mobility
- Agriculture
- Water
The thread running through all of it is simple: deployment-first climate solutions.
Founder Outreach Fit
When reaching out, lead with pilot agreements, LOIs, and a clear commercialization timeline. Just as important, show evidence that the product has been validated in field conditions.[1][2]
6. VoLo Earth Ventures
If Elemental puts money into deployment, VoLo Earth puts money into the systems and supply chains that let that deployment grow. The firm focuses on the infrastructure behind solar, wind, and storage, with extra attention on grid software, industrial decarbonization, and critical materials. You can see that thesis in its approach: it invests early, goes deep on technical work, and stays close to manufacturing. [7]
Typical Check Size
VoLo Earth typically co-leads $10 million to $15 million Series A rounds. [7]
Stage Focus
VoLo Earth focuses on Seed and Series A for hard-tech companies moving from prototype to production. [7]
Portfolio Themes
Its portfolio goes after system bottlenecks, including grid orchestration and critical metals supply. Texture manages interconnection backlogs for renewable deployment. Nth Cycle is onshoring critical materials that support storage and clean-energy hardware. [7]
Founder Outreach Fit
Founders should show standalone unit economics, signed customers, or de-risked manufacturing. It also helps to be ready for a nuts-and-bolts conversation about offtake, permitting, and supply chain exposure in concrete terms. [7]
7. SET Ventures
SET Ventures leans away from hardware-heavy infrastructure plays and toward European energy-tech scale-ups. The firm is based in Amsterdam, was founded in 2007, and focuses on backing European energy-tech companies as they grow. [3]
Typical Check Size
SET Ventures does not publicly share a standard check size. [3]
Stage Focus
SET invests from early stage through growth equity. Its sweet spot is scale-ups, and the team is known for active board participation. [3]
Portfolio Themes
The portfolio is centered on smart energy, distributed energy, storage, and grid-scale tech. It also includes 18 solar investments. [3]
That setup tends to fit founders who can show that software, data, and hardware don't just sit side by side - they work as one system in the market.
Founder Outreach Fit
This firm is a strong match for founders planning European market expansion. When you reach out, make the case in plain terms: show how your software or data layer improves the economics of your hardware. Also be ready for a hands-on investor relationship, including board seats. [3]
8. Chrysalix Venture Capital
If the earlier funds leaned more toward energy software or deployment, Chrysalix sits closer to the hardware and manufacturing side. The firm backs energy and industrial hardware scale-ups, with a focus on Series A and Series B companies in the United States, Canada, and the Netherlands. As of May 2026, it had completed 21 energy-sector deals, which puts it among the top 50 most active VC funds investing in energy startups. [8]
Typical Check Size
Chrysalix usually joins rounds between $2 million and $20 million. If your raise falls outside that band, it may not be the right fit. [8]
Stage Focus
The firm invests at the Series A and Series B stages. Founders should come prepared with traction, pilot results, or a clear plan for scaling. [8]
Portfolio Themes
Chrysalix focuses on energy, manufacturing, and cleantech. It tends to be a stronger match for hardware-heavy companies in solar, wind, or storage. [8]
Founder Outreach Fit
Reach out if your round is between $2 million and $20 million, your company is based in the U.S., Canada, or the Netherlands, and you can show technical validation along with early commercial proof. That puts you much closer to the kind of industrial clean energy company Chrysalix tends to back. [8]
9. Cycle Capital
Cycle Capital stays focused on the hardware and systems side of clean energy. The firm backs early- to growth-stage companies, with the strongest match in grid, storage, and battery infrastructure.
Typical Check Size

12. Energize Capital
Energize Capital invests in digital and software-led companies that improve the way clean energy assets get deployed and run. For founders in solar, wind, and storage, that usually makes Energize a better fit when your software helps with deployment, day-to-day operations, or grid integration.
Typical Check Size
Not publicly disclosed.
Stage Focus
Not publicly disclosed.
Portfolio Themes
Grid software, modernization, and operations software for clean energy assets.
Founder Outreach Fit
When you reach out, lead with proof instead of vision alone. Show pilots, unit economics, and a clear plan for scale. In plain English: they’ll likely want to see that the product works, that customers find it worth paying for, and that growth won’t fall apart as demand picks up.
13. Prelude Ventures
Founded in 2013 and based in San Francisco, Prelude Ventures backs early-stage climate startups. It doesn’t stick to energy alone, but its solar exposure puts it squarely on the radar for founders in this space. As of May 2026, the firm has made 19 investments in energy startups [8].
Typical Check Size
Prelude joins rounds ranging from $7.6 million to $130 million [8].
Stage Focus
The firm focuses on early-stage companies, with deal activity spanning Series A through Series C [8].
Portfolio Themes
Prelude invests across climate tech, and solar stands out as a clear area of focus. Its portfolio includes 17 solar investments [3].
Founder Outreach Fit
If you’re building in clean energy, the big test is simple: can your company cut emissions at scale and deliver venture-style returns?
Prelude looks for category-defining companies with clear room to grow and measurable emissions impact. In your outreach, lead with the numbers that matter most:
- Market size
- Traction
- Impact data
That’s the stuff that helps the story land fast.
14. OGCI Climate Investments
OGCI Climate Investments matters here because it funds emissions-cutting tech tied to the industrial energy transition. It’s a specialized investor backed by major oil and gas companies, with more than $1 billion under management. If you’re building climate infrastructure for heavy industry, this is a niche capital source worth knowing about.
Typical Check Size
Not publicly disclosed.
Stage Focus
Not publicly disclosed.
Portfolio Themes
The firm invests in methane detection and mitigation, carbon capture, utilization, and storage (CCUS), and industrial efficiency. In plain English, it’s a fit for startups working to cut emissions in oil, gas, and heavy industry.
That changes how founders should frame the pitch. Don’t lean on broad climate language. Lead with hard numbers, clear use cases, and where the product fits in day-to-day industrial operations.
Founder Outreach Fit
Lead with:
- Operational emissions impact
- Buyer relevance in oil, gas, or heavy industry
- Proof of traction
This is the kind of investor that wants to see emissions cuts tied to commercial adoption. If the product saves money, reduces risk, or helps industrial buyers hit emissions targets, say that early.
15. Lowercarbon Capital
Lowercarbon sits in the middle of two worlds: climate venture and capital-heavy energy deployment. The firm backs climate startups that can return venture-level outcomes, from emissions-focused software to energy tech that needs a lot more capital upfront.
Typical Check Size
Lowercarbon mainly invests at Seed and Series A [8].
| Stage | Typical Round Size |
|---|---|
| Seed | $2.7M – $11M |
| Series A | $6.5M – $50M |
Stage Focus
As of May 2026, Lowercarbon had made 32 investments over the prior 12 months [8].
Portfolio Themes
Lowercarbon had made 16 solar investments, and it also backs carbon removal and geothermal companies. These are capital-heavy climate businesses, but they also have clear paths to revenue [3][8]. Recent examples include Zanskar’s $115 million Series C+ and Cloover’s €1.04 billion Series A [9].
Founder Outreach Fit
This mix tells you a lot about what founders should lead with. Climate impact matters, but it won’t stand on its own. You also need to show a financing plan that fits the company you’re building.
For hardware or project-heavy startups, spell out how the cap stack comes together. For software-led companies, tie the product straight to measurable emissions cuts [9]. Lowercarbon’s portfolio is also concentrated in the United States, the United Kingdom, and France [8].
16. DCVC
After years of capital-heavy climate deals, DCVC puts the spotlight on software-led energy tools. The firm focuses on deep tech, with a sharp interest in AI and software built to solve energy problems.

Founder Outreach Fit
Founders building software or systems that improve energy, buildings, or industrial operations in North America or Europe are the best fit [3]. For solar, wind, or storage startups, the main question is simple: does the product help deployment, day-to-day operations, or asset performance?
18. Ansa Capital
Ansa Capital invests in growth-stage energy-transition companies. In plain terms, that means it looks for businesses that have moved past early proof and are now focused on scaling.
Typical Check Size
Ansa Capital has not publicly shared its usual check size.
Stage Focus
The firm focuses on Series B and Series C companies with proven traction and a clear path to scale.
Portfolio Themes
Ansa Capital backs software-led energy-transition platforms tied to:
- efficiency

What Founders Should Do Before Reaching Out
Cold outreach often falls flat for a simple reason: the round, stage, or business model doesn't line up with the fund. Before you send a deck, filter each firm first.
Match Your Ask to the Fund's Stage and Check Size
Before you write a single line, make sure your round size and stage fit the fund's mandate. This sounds basic, but it's where a lot of outreach goes off the rails.
Multi-stage firms often divide capital by stage. That means you need to aim for the right fund and the right partner, not just the right logo on the website.
Present Your Model as Hardware, Software, or Project-Enablement
Once stage and check size line up, explain the business in the investor's language. The way you position the company matters just as much as the tech.
Give the model in one clear line, then connect it to the fund's thesis. Is the company best framed as hardware, software, or project-enablement? That call shapes how a fund prices risk and upside.
Back Your Pitch With Pilots, Timelines, and Unit Economics
After the model is clear, bring proof. Lead with pilot results, commercial milestones, and unit economics.
For infrastructure-linked companies, things like signed PPAs, interconnection agreements, or ready-to-build status can remove a big risk flag early in the conversation. You also need to show that the unit economics still work under current policy conditions.
Get Your Financial Materials in Order First
Next, package the numbers into investor-ready materials before outreach. Your model should be ready before you contact anyone.
If your finance stack isn't ready, Phoenix Strategy Group can help with bookkeeping, fractional CFO services, FP&A, data engineering, and fundraising support.
Key Takeaways
Start with fit: stage, check size, and business model. These firms vary on all three, and the wrong match can sink a good pitch.
Once stage and check size line up, look at whether the fund leans toward software, hardware, or project-enabled models. Your pitch should speak to how a given fund sees risk and return, not just what the tech does. [3]
Before you reach out, lead with pilots, unit economics, and financial readiness. Investors want proof that the product works, that customers will pay for it, and that the numbers stand up when someone digs in.
Use this list to narrow your targets before outreach.
FAQs
How do I know which VC firm is the best fit for my startup?
Match the firm’s stage and traction requirements to where your startup is right now. Then spell out the unit economics investors are likely to back.
For early-stage companies, focus on funds that write checks at Seed–Series A once there’s clear market signal. That can look like signed enterprise contracts, paid pilots that convert, or strategic partnerships that show buyers are taking you seriously.
If you’re building in solar, wind, or storage, make the business model easy to underwrite. Put recurring revenue front and center. Show that the company still works after policy tailwinds fade. And be direct about exit paths, including M&A or IPO timing and fit.
What should I prepare before reaching out to clean energy investors?
Show strong balance-sheet discipline, clear financial health, and positive unit economics that still work without older tax-credit setups. Then build a detailed pitch deck that covers your business model, market opportunity, social impact, financial projections, team, and traction.
If your operation is more mature, come prepared with a QofE report that clearly separates project-EPC value from recurring O&M annuity revenue. That split matters because recurring revenue is a major driver of valuation.
Do software and hardware startups need different clean energy VCs?
Generally, no. Clean energy VCs don't need to be strictly software-only or hardware-only.
What matters more is stage, business model, revenue stability, and how tightly the offering is built into the customer's work. Tech-enabled, software-driven platforms may earn higher valuations, while more classic equipment businesses may trade at lower levels. So founders should focus on investor fit, not just the software vs. hardware label.
