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.

What Is Fixed Tilt, Single, or Double Axis Racking?

Solar panel racking is a mundane yet vital part of any utility-scale solar installation. 

Harnessing solar energy is more than simply pointing panels at the sun. Despite looking like simple infrastructure, ground-mounted racking can vastly improve a solar operation’s overall performance. 

Racking systems allow operators to precisely angle panels to optimize generation and maximize results over the system’s lifespan. Luckily, solar EPCs have access to several types of racking systems to fit any budget, environment, or climate. 

Fixed Tilt Solar Racking 

True to its name, fixed tilt solar racking holds the solar panel at one tilt angle. 

Since the panels do not track the sun’s movement, installers must find the angle that maximizes sunlight absorption. This angle, called the azimuth, helps the panel collect as much sun as possible during peak hours. 

Azimuth angles use true north and the sun’s position to find the perfect direction to face the sun. To calculate the azimuth, developers can use the National Renewable Energy Laboratory’s Solar Position Algorithm to get results within 0.0003 degrees. 

Pros of Fixed Tilt Racking 

So, why do solar EPCs like using fixed-tilt systems for certain projects? It comes down to ease of installation and upkeep, durability, and application. 

Fixed tilt systems don’t have complex tracking systems, making them easy to install almost anywhere, ultimately saving time and labor costs. The system’s straightforward design also makes it useful across residential, community, and utility-scale projects. 

Fixed-tilt systems are more durable than other options. They need little maintenance over their usable lifespan and have a low risk of losing the sun’s position. The racking systems also do well in poor weather conditions, including where snow could be an issue. 

Finally, installers prefer fixed tilt systems when working with brownfields and other challenging landscapes. Brownfields are former industrial or commercial sites that may have environmental contaminants, making them unattractive for regular development. In cases like this, solar panel systems stationed in poured concrete hold up the panels without disturbing the ground too much. 

Concrete pads or blocks work in other challenging locations, too. Rolling hills make it hard for some tracking systems to work, but fixed-tilt systems don’t have similar problems. 

Cons of Fixed Tilt Racking 

Despite being cost-effective, durable, and easy to install, fixed tilt racking falls short in other ways. 

Because the racking system doesn’t move, solar panels don’t follow the sun through the sky. This limits the amount of sunlight the panels absorb, making them less efficient. 

Less efficiency also leads to another problem – less production. To offset the lack of production, developers may need to install more panels to achieve better results. The additional panels require space, leading to higher land costs and expenses. 

Shading can also cause issues for solar panels attached to fixed tilt racking because of their lack of movement. If a tree casts shade on a section of solar panels, their production plummets without a way to change direction. 

Single Axis Systems 

Unlike fixed-tilt mounting systems, single-axis ones follow the sun using tracking components. 

Because the system tracks the sun, panels collect more sunlight, leading to better solar power generation. Though they cost more than fixed-tilt options, their increased output means sites need fewer panels to produce the same power. 

To save money, developers can also install panels in long rows, using one drive system to control all the trackers at once. The cost is a little more burdensome in tight areas with shorter aisles because the installation requires more drives. 

Pros of Single-Axis Racking 

Single axis tracking setups are more expensive but prove their value by increasing long-term electricity generation. 

Moving, even in one lateral direction, makes a dramatic difference for most systems, including those in small spaces. Experts suggest single-axis setups are somewhere between 15-30% more efficient than fixed-tilt ones. This is because panels can keep pace with the sun all day. 

Furthermore, single-axis racking reduces impacts caused by shade. As the sun moves, the panels follow, as opposed to becoming trapped at a bad angle for hours on end. 

Cons of Single-Axis Racking 

When you introduce more complexity to a system, you increase the risk of something going wrong. 

While fixed tilt systems offer an easy-to-maintain, no-frills experience, single-axis systems need more maintenance. They also require space to allow the panels to safely move along their axis. When space is an issue, there may be less room for panels. 

Increasingly complex systems also come with higher price tags, as developers can expect to pay more for a single-axis system, compared to a fixed tilt one. Though the price may cause some cost-conscious developers to shy away, the added generating power helps soften the blow. 

Finally, it’s worth noting that single axis tracking systems don’t always perform well on difficult terrain. Whether it’s hilly areas, brownfields, or other tough conditions, setting up panels in one row is hard. As a result, solar EPCs must find creative ways to safely run these systems. 

Double (Dual) Axis Systems 

What’s better than a solar panel that follows the sun across the sky? How about a solar panel that tracks the sun’s elevation at the same time? 

Not only do double-axis trackers follow the sun east to west, but they can also move north to south, tracking elevation too. PV systems outfitted with dual-axis solar racking systems are up to 40% more efficient than standard fixed tilts. The result is a system capable of generating maximum electricity every day of the year. 

Pros of Double-Axis Racking 

One benefit of being incredibly efficient is that installations can often do more with less. 

When panels follow the sun better, farms need less space and fewer panels to achieve similar results. For developers, it means getting more power out of the same plot of land, reducing project costs. 

More importantly, double-axis tracker systems can negate issues caused by shade or clouds. When shade covers the panels, they can be repositioned, optimizing the situation and generating clean power. 

Cons of Double-Axis Racking 

Better technology often means higher costs. 

For some solar developers, the high upfront cost to install double-axis racking can be a tough pill to swallow. Unlike fixed-tilt trackers, these complex systems often require skilled workers to install, calibrate, and maintain them. 

Maintenance is critical to keeping a double-axis system running smoothly. If the trackers don’t work, they can’t follow the sun, hurting overall production and return on investment. However, with proper maintenance and care, the farm can “pay” developers back over time. 

Finally, it’s possible that even with proper maintenance, tracker components may wear out before the panels. Panels can go decades with only routine maintenance and cleaning, but moving parts tend to show wear and tear much sooner. 

Options for Every Installation 

Every installation is different, so developers and their teams should decide what racking is best for their situation. 

Budget-friendly options are easy to install and perform well across a variety of landscapes but are less efficient. Tracking systems dramatically increase energy generation but are more expensive and need more maintenance. 

No matter what, work alongside qualified companies and partners who understand your project’s needs and goals. Their experience and expertise can help you avoid pitfalls and navigate unexpected problems, making installations smoother and more productive.
