How Can Solar Developers Reduce Labor Costs?

It’s been about a year since President Donald Trump signed the One Big Beautiful Bill Act (OBBBA) into law, drastically cutting federal support for the solar industry. 

The move immediately made ITC and PTC incentives harder for solar developers and EPCs to access. It also shortened the timeline for projects to qualify for them, and sunset deadlines and tax incentive timeframes. 

While the initial shock left the industry reeling (especially residential solar installers), overall solar growth has been resilient. The rules are different, but savvy solar companies are rolling with the punches. 

However, losing federal tax incentives highlights a glaring issue: projects just became more expensive. With that fact in mind, developers and EPCs need to control costs while maintaining quality standards. 

Creative Cost-Cutting 

Fewer tax credits and incentives are available, but solar EPCs can still maintain a positive internal rate of return (IRR). 

IRR measures the profitability of a proposed solar site over the span of its usable lifetime, and includes factors like: 

  • The project’s initial cost 
  • Operations and Maintenance expenses 
  • Potential and realized cash savings (rebates, electricity sales/savings, and other benefits) 
  • The project’s usable lifespan – typically 25-30 years 

With so many variables, developers can pull levers in one area to compensate for issues in another, offsetting or improving the overall IRR. In this case, as rebates and tax credits eventually dry up, we can lower costs and improve maintenance by maximizing labor. 

Why Is Labor the Next Cost-Saving Measure? 

We’ve seen firsthand how quickly the solar development landscape can change – for better or worse. 

According to the National Renewable Energy Laboratory (NREL), solar power’s levelized cost of energy (LCOE) has plummeted since 2010. Over the last 15 years, costs fell roughly 86% for utility-scale solar systems and 84% for commercial installations. The agency noted that prices fell quickly for several reasons, including lower system costs, better technology, and improved operations. 

But while hard costs plunged, soft costs like labor, permitting, and taxes have been more stubborn. 

For years, solar companies fought to hire as many employees as possible to support a rapidly growing industry. Today, the goal has evolved from having large staffs to efficient ones. 

In 2026, the goal for EPCs and developers is to maximize productivity and minimize overhead. Since hard costs can’t fall much lower, the next option is to reduce labor costs. For many builders, it means finding ways to standardize builds, automate systems, and modularize components. 

Reducing Solar Labor Costs 

Since solar companies can’t do much to reduce the cost of permitting, fees, and taxes, reducing labor costs is the next best option. 

To save on labor, we can either reduce overall headcount or improve productivity. Since reducing headcount is a drastic measure, optimizing installs is often a better long-term solution. 

But what can developers do to maintain operations while preserving bottom lines and IRR? 

Automate Installations When Possible 

Automation has been a lifesaver for many industries, as robots perform repetitive tasks, while allowing people to do higher-value work. 

Robots, artificial intelligence, and drones have many applications in the field, both physically and virtually. For example, robots can use GPS tracking to precisely dig pilot holes or move and install heavy racking. They can also precisely install panels onto racks, all under a worker’s watchful eye. 

With an unmatched blend of speed, accuracy, and dependability, automated robots and other high-tech gadgets are taking solar by storm. Companies like Terabase say their bots can automate construction, cutting costs and freeing workers for other tasks. Not only does the system double productivity, but Terabase says Terafab® work is safer and of better quality, too. 

Terabase is only one automation company, but it’s part of a burgeoning robotics industry. As the technology improves and automated system costs stabilize, expect adoption to rise dramatically. 

Lean on AI Mapping 

Artificial intelligence is a white-hot topic, so it’s no shock that solar companies have found ways to use it effectively. 

One of the easiest ways to implement AI into solar projects is to assist engineers with site configurations. Today, a team of engineers may create, test, and review potential solar project layouts, which is time-consuming and costly. 

With AI tools, solar engineers simply upload data and wait for the system to spit out results. Once the review is ready, the team checks its work to test the design’s feasibility. 

In this case, solar companies need fewer engineers for each project, allowing them to spread out across more projects. This increases productivity and shortens timelines for solar projects across the entire portfolio. 

Beyond site testing, AI is also helpful for creating digital twins of solar sites. Digital twins are exact virtual versions of physical objects or designs and help engineers spot potential problems before breaking ground. These replicas mimic planned sites, giving teams visibility into what the final project might look like and how to improve it. 

AI is expanding quickly, but even supercomputers get answers wrong sometimes. Project engineers should ensure the data fed to the system is accurate and double-check every output. However, if everything checks out, artificial intelligence can improve performance and mitigate fail points during development and operation. 

Pre-Fab and Modular Solar Materials 

When time is money, the easiest way to reduce labor costs is to shorten timelines. 

One way to accomplish both goals safely is to reduce the amount of boots-on-the-ground time workers spend assembling solar installations. Luckily, you can modularize most parts of a utility-scale solar site, including foundations, racking, and even PV wire. 

PV Wire 

PV wire is a small part of the overall solar project cost, but plays an oversized role in the project’s performance. 

When workers field-install PV wire connectors, it slows them down and may lead to potential mistakes. These mistakes can result in loose fittings, reduced performance, and even arcs, sparks, and fires. 

Pre-fab PV wire eliminates a critical fail point during installation. Manufacturers can bundle and fit PV wire with pre-tested, uniform connectors for fast field installation. Ultimately, pre-fitted connectors and bundled wire reduce installation times and increase project quality. 

Racking 

Racking is a durable, weather-resistant framework that holds PV panels in place. Depending on the need, crews can install fixed-tilt or single/double-axis racking to maximize energy generation. 

Like PV wire, workers can build racking systems off-site, then deliver them to the jobsite for installation. Developers can also attach pre-fab racking to modular foundations or ground-mount systems to further streamline processes. 

For developers, pre-fab racking takes additional risk out of the project. First, workers don’t have to worry about weather delays slowing them down as they weld pieces together. Secondly, critical welds and other delicate fabrication work are happening off-site, ensuring every weld passes inspection. 

Lastly, because these systems install more easily, solar EPCs can use less experienced labor and still maintain speedy production.

eBOS, Simplified 

In 2026, simplicity and speed are paramount. Thankfully, companies have no shortage of modularized parts. 

Modularization helps developers move quickly to bring sites online while saving time, labor, and headaches. But beyond making initial set-up a breeze, pre-fab parts come in handy during maintenance as well, reducing downtime when something needs replacing. 

So, which eBOS parts have pre-fab options available? 

  • Combiner boxes with customized string configurations 
  • Wire harnesses, clips, and brackets to hold PV wire in place 
  • Factory-molded and installed field connectors for safe, secure connections 
  • Factory-made concrete ballasts reduce weather-related risks and debris affecting concrete integrity 

In each case, pre-fab parts keep as much work off-site as possible. When done well, developers need fewer workers to do more work while maintaining safety. Plug-and-play pre-fab parts and pieces later reduce downtime and maintenance costs by being easy to install and replace. 

More Focus on Standardization 

Standardization, as the name implies, strives for similarity. 

The idea behind standardization is that it creates familiarity over time. Once workers understand how to work with the assigned parts and pieces, they can quickly and confidently perform work across any site using those parts. 

And, like modular parts, standardization creates simplicity. Complex installations require more expensive workers, more time learning new systems, and longer development timelines. When developers can simplify the process and components used at each location, workers can get more done each day. 

Long story short, simple saves time, money, and effort without sacrificing quality and reliability. 

Working With the Landscape 

Sometimes, investing in the right spot to build is the easiest way to save time and labor costs. 

Usually, this means looking for stable locations where the ground requires little prep work. Excavating, moving and grading land, and adding infrastructure takes significant time and cost. 

To reduce labor costs, we can start by finding easier locations to build on. Brownfields like landfills, coal mines, and other locations, sometimes already have infrastructure from previous uses. From roads and substations to other land development, these sites can supercharge solar project timelines. Pre-established substations also make it much easier for solar sites to interconnect to the grid later. 

Companies can also look for locations where digging and grading may not be necessary. Crews can avoid excess work by using pre-fab foundations or ballasts, or by using racking systems that work with steeper slopes. In both cases, crews can remove a step or two from the preparation process, cutting crucial time from the timeline. 

Controlling Labor Costs is Possible 

Despite declining federal support and financial incentives for large-scale solar development, solar energy companies still have wiggle room. 

Today’s economy is about doing more with what you have and prioritizing safe, efficient installs every time. With strategic investments in emerging technology and approaches grounded in simplicity, developers can reduce labor costs without losing quality. 

The clean energy industry has the opportunity to embrace cutting-edge technologies, including artificial intelligence. AI is useful in many instances, from checking permits and creating digital twins to remote monitoring on completed sites. In each case, technology frees up engineers and workers to focus on higher-caliber tasks. 

Additionally, robots can fill roles that recruiters couldn’t hire for. The solar industry still struggles to find talent, so supplementing teams with automated robotic solutions makes sense. Robots are fast, accurate, and meticulous; when supported by eagle-eyed workers in the field, projects move faster without forfeiting safety. 

Keeping the Industry Moving 

Ultimately, reducing labor costs for solar developers and EPCs provides massive benefits for companies and the industry. 

More efficient labor improves the bottom line, streamlines project timelines, grows profit margins, and enhances scalability. And with so many large-scale U.S. initiatives, including data centers and electrification efforts, solar has no time to waste.

Making the Case for Prefabricated Solar PV Wire Solutions

Driving past a solar installation sometimes feels daunting. Arrays can have dozens of rows of panels, stretching on for what feels like miles. 

Not only are some solar energy projects massive, but they’re also complex. Companies have hundreds of variables to consider, and the process takes years from initial planning to completion. They also cost millions of dollars between installing solar panels, securing permits, doing tests, and paying employees. 

Solar EPCs always try to manage costs, reduce installation times, and produce better results. While hard costs like solar panels and PV wire have fallen over the years, soft costs like permitting, taxes, and labor haven’t shown the same decline. 

How can companies save money on soft costs? The answer may be found in the wire holding everything together. 

Small Cost, Massive Impact 

When we look at the total cost of a utility-scale solar energy system, PV wire is low on the list. 

However, choosing the right solar wire can save time and money on your solar project installation. For example, prefabricated wires have a higher upfront cost but slash installation times. 

So, how do bundled, prefabricated solutions make the most of their engineering to save time and money? It all comes down to ease of use, consistency, and automation. 

When combined, teams can shave hours and dollars off their projects without additional effort. 

Why Do Installers Choose Pre-Fab Solutions? 

Despite all the planning and effort, sometimes you get what you pay for. 

Using single PV cables for a rooftop solar system is fine, but they can slow a utility-scale project to a crawl. Bundled pre-fab cables remove constant trips up and down each row, replacing them with one pass. 

For the average project, not making multiple trips shaves hours off each row and days off a project. But beyond faster installations, why are solar companies choosing pre-fab wire products? 

Wires are Pre-Cut and Factory Assembled 

What is the difference between a pair of jeans purchased off the rack and a custom-tailored pair? 

Jeans from the store come in many sizes, but they only offer a general fit. Meanwhile, custom-tailored jeans are specifically manufactured to fit you and only you. The same concept applies to buying single wire reels versus pre-fab bundled wire. 

Manufacturers cut pre-fab bundled cable to specific lengths matching the project’s layout, preventing wasted wire. The manufacturer also properly installs connectors, performs quality control testing, adds labels, and mounts the cable to reels. 

Not only are the manufactured cables ready to install as soon as they reach the job site, but workers don’t have to cut, crimp, or install connectors themselves. 

Less Room for Mistakes 

Employees on the job site often have varying skill levels and experience. 

Small mistakes, like a loose connection, can have dangerous implications. Fires, arcs, and shorts may cause severe damage and cost hundreds of thousands of dollars to repair or replace. 

Factory testing eliminates many issues before installation occurs. The manufacturer is also much more consistent than multiple workers on the job site. 

The other thing installers like about pre-fab wire solutions is the exact measurements used to cut each wire to length. Single wire reels often create waste during installation. Despite the higher cost, pre-fab solutions limit scrap and speed up installs because workers can immediately use them. 

Building on Labor Savings 

Pre-fab solar power cables help workers make fewer mistakes, but do they make installers faster?  
 
Instead of walking cables one at a time down the row to each solar panel, installers make one trip with all the cables. Once they reach the end of the row, they walk back down and connect each wire in the bundle to its corresponding panel. Customers can have cables marked as well, further reducing accidents and miscommunication. 

Pre-fab solutions, including bundled wire, limit opportunities for mistakes. The faster speeds also reduce labor costs dramatically, sometimes by as much as 80%.

Besides allowing works to move more swiftly on the worksite, pre-fab solutions also make solar installation teams more efficient. In many states, including those across the Northeast, solar projects ramp up in the spring and slow down toward the end of fall for the winter season. The ebb and flow of project seasonality, which is a challenge for many solar companies. 
 
When teams are using pre-fab bundled wire, projects are completed more quickly with fewer people. In turn, crews can work on more jobs during the busy season, and companies benefit from better labor allocation and shorter ramp-up and ramp-down times. 

Safer Installs 

Prefabricated PV wires are easier to work with, simplifying the job. 

Think about field-made connectors for a second. Depending on the workers’ experience, they could make mistakes as they strip, crimp, and attach connectors to the wires. While issues may not appear immediately, they could develop over the long term, limiting power generation. 

Bundled solutions remove the guesswork from the installation process. Workers only attach the connectors to the panels and the combiner box to power the system. 

Beyond being easy to use, prefabricated bundled wire is also cleaner, as there’s only one bundle of wires to worry about. The result is an organized installation with fewer mix-ups and nicer-looking outcomes free of tangled wire. 

Short- and Long-Term Savings 

Pre-fab wire solutions like bundled cable cost more than single cable options but save time and money on labor. 

Single wire reels work for small residential solar panel systems but bog down larger projects, like utility and community solar. Running single-wire reels is inefficient, more error-prone, and opens the door for waste. 

Combining the wires for a row together shortens installation times and gets workers on and off the site faster. Best yet, potential savings increase as the projects get bigger. 

Bundled Wire Leads to Better Installs 

The United States relies on clean energy more than ever, so investing in solar improvements is critical. 

Solar array technology has improved dramatically, from bifacial panels and tracking systems to more effective connectors and accessories. The same can be said for PV wire, too. 

Bundled PV wire solutions allow employees to do better work faster. Solar installations can then produce energy sooner, leading to lower electric bills for communities and businesses. 

That’s good news for everyone.
