Why 200 Applicants Still Isn’t Enough: Passive Candidate Sourcing in Solar and Renewable Energy
By: Jon Semingson
A large applicant pool can create a false sense of confidence, especially in solar and renewable energy. More resumes do not mean you’re seeing the best candidates. It means you’re seeing everyone who happened to be looking on the day you posted the job.
In an industry where nearly 90% of solar employers report difficulty filling open roles, that gap between “lots of applicants” and “the right candidate” is showing up in hiring decisions constantly.
Quick answer
- Passive candidate sourcing means proactively identifying and reaching out to qualified people who aren’t actively job hunting, typically because they’re already employed at a competitor, an EPC, or an adjacent energy company.
- Nearly 90% of solar employers struggled to fill open positions in 2024, and 47% said management-level roles were hardest to fill.
- Solar, storage, and grid talent is also being pulled into data centers, nuclear, and other power sectors competing for the same skillsets.
- The strongest hiring decisions in this market compare both active applicants and passive candidates sourced directly from the industry before making a final call.
The pattern we keep seeing
A solar project manager or battery storage engineer role gets posted. Two hundred applicants arrive. Interviews start. A few strong candidates emerge. And yet, confidence stays low, and the hiring team wants to see more people before committing.
That hesitation isn’t indecision. It’s usually a signal: the team is missing market comparison. They’ve evaluated who applied, but they haven’t evaluated who’s out there building similar projects at other developers, EPCs, or IPPs. Without that second data point, it’s hard to know whether “pretty good” is actually the best available, or just the best of who happened to apply.
We’ve watched this play out with clients directly. A search for a high-voltage electrician or SCADA specialist reaches the interview stage with one strong finalist. The client likes them, but isn’t sold enough to pull the trigger, because they have no reference point for what else exists in the market.
In our experience, that hesitation resolves itself once they see two or three comparable people sourced directly from competitors or adjacent sectors. Sometimes the original finalist still wins. But now it’s a decision made with evidence, not a guess made under pressure.
Why this is especially true right now in renewables
The solar industry alone now supports over 280,000 workers, but it will need roughly 355,000 by the end of 2026 to hit installation targets of 60 to 70 GW, leaving a projected gap of about 53,000 positions (pv magazine USA).
At the same time, clean energy jobs grew three times faster than the overall U.S. workforce in 2024. Wind turbine technicians and solar PV installers have been the two fastest-growing occupations in the country for three years running.
That growth is colliding with a shortage. Nearly 90% of solar employers reported difficulty filling positions in the 2024 IREC National Solar Jobs Census, with 53% citing a lack of experience, training, or technical skills as the top barrier, and 47% saying management roles were hardest to fill (IREC).
Additionally, solar companies are now competing for talent across the broader energy and infrastructure market. Battery storage, data centers, nuclear, and grid modernization projects are all recruiting from the same pool.
Skills like SCADA systems and high-voltage electrical work transfer easily across sectors, so solar’s best people are constantly being courted elsewhere (pv magazine USA).
Active market vs. passive market, defined
Active candidates are people currently applying to open roles. They’re visible, they’re accessible through a job posting, and they’re always worth interviewing. Some of the best hires still come from this pool.
Passive candidates are people who are not actively job hunting or broadly applying for new roles. In renewables, they’re usually already employed at a developer, EPC, OEM, or utility, often on active project timelines, and they almost never show up in an inbound pipeline because they’re not looking. Reaching them requires direct outreach, industry relationships, and targeted search, not a job posting.
| Active candidates | Passive candidates | |
|---|---|---|
| Currently job hunting | Yes | No |
| Found via job postings | Yes | Rarely |
| Employment status | Often between roles or open to change | Usually currently employed on active projects |
| Hiring difficulty reported by employers | N/A | ~90% of solar employers report difficulty filling roles (IREC) |
| How to reach them | Post the role | Direct outreach, industry networks, project tracking |
| Cross-sector competition | Limited | High, competing with storage, data centers, nuclear, grid |
The numbers matter here: with a projected 53,000-person gap in solar alone and management roles the hardest to fill, a job posting is, by design, only reaching a slice of the people qualified to do the work. That’s not a criticism of job boards. It’s a reminder that they’re one input, not the whole strategy.
It’s also worth separating “passive” from “unreachable.” Recruiters who specialize in renewables consistently find that top performers, even those fully engaged on a current project, will consider a move for the right opportunity when approached directly rather than through a posting (iRecruit.co).
Signs you’re missing market comparison
A few patterns tend to show up when a renewable energy hiring team is only seeing the active pool:
- You’ve interviewed several applicants for a technical or project leadership role, but no one feels like a clear “yes.” Not because the candidates are bad, but because you have nothing to measure them against.
- The search keeps getting re-opened. You re-post the role, re-run interviews, and end up back where you started, a sign the team is looking for confidence, not better candidates.
- The role is specialized: SCADA, high-voltage, grid interconnection, or project management. These are exactly the roles IREC data shows are hardest to fill, and where the people best qualified are usually already employed on someone else’s project.
- Your best applicant is currently employed on an active project too. If your strongest candidate came from a job posting despite already having a role, that’s a good sign. But it also means there are likely others like them who never saw the posting at all.
What “missing market comparison” actually costs you
When a hiring team only sees active applicants, three things tend to happen:
Confidence stays artificially low. Without a comparison point, “good” and “best available” look identical, and teams second-guess a candidate who might genuinely be the right hire.
Searches drag on, which is expensive in this market. Every extra month a project management or engineering seat stays open pushes back project timelines that are already competing against tight tax credit deadlines and interconnection windows.
The strongest people never enter the conversation. The candidates most likely to change the trajectory of a project (the ones already delivering on someone else’s build) are structurally excluded from a strategy that only looks at inbound applications.
A practical framework for comparing both markets
No single sourcing strategy works for every role. But relying on only inbound applicants narrows your view of the market more than most renewable energy hiring teams realize. A workable approach:
- Post and interview the active pool. Don’t skip this step. It’s fast, low-cost, and sometimes the right hire is already in the pipeline.
- Run a parallel passive search for the roles that matter most. For project managers, engineers, SCADA specialists, and other hard-to-fill roles, identify strong performers at competitors, EPCs, or adjacent energy sectors and reach out directly.
- Compare, don’t default. Put your strongest applicant next to your strongest sourced candidate before deciding. Sometimes the applicant still wins. That happens all the time. The point isn’t to distrust your pipeline, it’s to know you looked.
- Match the strategy to the role and the timeline. A high-volume installer role may not need passive outreach. A senior engineering or project leadership hire almost always benefits from it, especially against a tight deployment deadline.
How passive sourcing actually works in renewables
Passive candidates in solar, storage, and wind don’t respond to job postings, so reaching them looks different from posting-and-waiting. In practice, it usually involves a combination of:
- Direct, targeted outreach: identifying people in similar roles at competing developers, EPCs, or OEMs and reaching out individually, rather than broadcasting to everyone.
- Tracking project announcements: following who’s staffing up for newly announced solar, storage, and grid projects often surfaces exactly the experienced people worth a conversation.
- Industry relationships and conferences: the kind of network built over years of attending solar and storage industry events and staying close to who’s doing strong work where.
- Cross-sector searches: since skills like SCADA, high-voltage electrical work, and grid integration transfer across solar, storage, wind, and even nuclear, the right candidate for your role may currently be working in an adjacent part of the industry.
This is also where a recruiting partner with deep renewable energy relationships tends to add the most value over a general internal team: sourcing passive candidates well takes time, industry-specific networks, and tools most hiring managers aren’t set up to run alongside their day job.
The bottom line
More applicants doesn’t automatically mean more confidence. It means more of one type of candidate. In a renewable energy market where nearly 90% of employers struggle to fill roles and the best talent is often already deployed on someone else’s project, the strongest hiring decisions come from comparing who applied against who’s actually out there.

FAQ
What is a passive candidate in solar or renewable energy recruiting?
Someone who isn’t actively job hunting, usually because they’re already employed on a solar, storage, or wind project, but who would consider a strong opportunity if approached directly.
Why is passive sourcing especially important in renewable energy right now?
Nearly 90% of solar employers reported difficulty filling open positions, which means relying exclusively on inbound applicants can leave companies with a limited view of the available market.
Why would I need passive sourcing if I’m already getting a lot of applicants?
Applicant volume only tells you who was looking on the day you posted, not how your role compares to the rest of the market. Passive sourcing adds that missing comparison point.
Does passive sourcing mean my applicants aren’t good enough?
No. The original applicant often remains the strongest candidate after a market comparison. It’s a way to confirm the decision with evidence, not a vote of no confidence in your pipeline.
Is passive candidate sourcing worth it for every renewable energy role?
Not necessarily. It matters most for specialized or project-critical roles like engineers, project managers, and SCADA or grid specialists. High-volume installer roles are usually fine with active applicants alone.
Can I do passive sourcing myself, or do I need a specialized recruiter?
You can, through referrals and industry contacts, but building a cross-sector network for solar, storage, and grid talent takes years. Most teams handle active recruiting in-house and bring in a specialized partner for the passive search.
