Mercom Survey: Solar Graduates Need Months to Become Productive

Mercom India has released a new survey highlighting a notable gap in workforce readiness within the solar sector. The study drew on responses from more than 100 industry participants. These respondents represented four key segments of the industry: utility-scale projects, manufacturing, rooftop solar, and engineering, procurement, and construction (EPC).

The findings suggest that graduates entering the field often require several months to reach full productivity levels. This delay reflects a broader challenge in aligning academic training with the practical demands of current solar operations. While the survey provides a snapshot of these hiring and training dynamics, it does not establish a direct causal link between specific educational programs and time-to-productivity metrics. The data serves as a preliminary indicator for companies seeking to optimize their onboarding processes and internal training structures.

Productivity Timelines

The survey data reveals distinct timelines for new hires across different segments of the solar value chain. In manufacturing, the majority of respondents indicated that graduates require a substantial adjustment period to reach full capability. Specifically, 74% of these participants reported that it takes between three and twelve months for new employees to become fully productive. A smaller but notable portion, 7.4%, stated that the process extends beyond one year. These figures suggest that the transition from academic theory to factory-floor proficiency is not immediate, requiring extended onboarding and hands-on experience to bridge the gap between classroom learning and industrial application.

Rooftop solar companies face a similar, though slightly less prolonged, challenge in workforce integration. More than half of the respondents in this segment, representing 54% of the total, noted that graduates take over three months to become productive. This duration reflects the specific technical and client-facing skills required for distributed generation projects, where understanding system design and local regulations is as critical as hardware knowledge. The variance in these timelines highlights how different operational contexts influence the speed at which new talent can contribute effectively to project delivery and maintenance.

Raj Prabhu, CEO of Mercom Capital Group, summarized the broader implication of these delays. He stated, "The talent pipeline is not keeping pace." This observation underscores the disconnect between the volume of graduates entering the job market and the specific competencies that employers need to maintain operational efficiency. For companies managing these hiring cycles, understanding these specific productivity windows is essential for planning resource allocation and training budgets accurately.

Retraining Burden

Beyond the waiting period for full productivity, a significant portion of the workforce arrives with skill sets that diverge sharply from operational requirements. The survey reveals that employers frequently must invest in immediate corrective training rather than simple onboarding. Across all segments, 40% of respondents reported that between 25% and 50% of their new hires require retraining. Another 29.6% indicated that the proportion is even higher, with 51% to 75% of new employees needing this additional instruction to align with job specifications.

Segment	Respondents Reporting 25-50% Retraining	Respondents Reporting 51-75% Retraining
Overall	40%	29.6%
Utility-Scale	62.5%	37.5%

The utility-scale segment faces the most acute version of this issue. Here, 62.5% of respondents stated that over half of their new hires need significant retraining. 37.5% of these participants reported that the figure exceeds 75%, meaning that in many large-scale project environments, the majority of incoming talent lacks the specific technical proficiency required for immediate deployment. This pattern suggests that academic curricula often fail to cover the specialized operational protocols and safety standards inherent in large grid-connected installations. For project developers, this reality forces a strategic shift from hiring for general knowledge to budgeting for intensive, targeted skill remediation. Such internal training programs become a necessary operational cost, as they bridge the gap between theoretical education and the high-stakes, precision-driven demands of utility-scale solar development. This retraining burden also impacts project timelines, as engineers and technicians spend their initial months learning site-specific procedures rather than contributing to active maintenance or construction tasks.

Skill Gaps and Bottlenecks

• 50% of respondents noted that graduates lack understanding of grid congestion and curtailment risks.
• 75% of utility-scale developers identified a lack of practical exposure as the biggest hiring bottleneck.
• 37% of manufacturing respondents cited the same lack of practical exposure as their primary hiring challenge.
• 88% of EPC companies reported that field exposure, technical knowledge, or project development constitute hiring challenges.
• 42% of EPC companies stated that graduates can work effectively on live project sites.

The survey highlights a persistent disconnect between academic preparation and the operational realities of grid-connected solar energy. Half of all participants observed that new hires often do not grasp the complexities of grid congestion and curtailment risks. These concepts are central to modern power systems, where solar output must be managed dynamically to prevent overloading transmission lines. Without this understanding, engineers may struggle to optimize energy yield or comply with grid codes, leading to potential revenue losses and regulatory penalties for project owners.

Practical experience remains the most cited barrier to effective hiring. Three-quarters of utility-scale developers and over one-third of manufacturing firms identified a lack of hands-on exposure as their primary bottleneck. In the EPC sector, where project execution is time-sensitive, 88% of companies flagged field exposure, technical knowledge, or project development as significant challenges. Only 42% of EPC firms believed graduates could operate effectively on live sites immediately. This disparity suggests that classroom theory alone is insufficient for roles requiring immediate deployment in complex, high-stakes environments. For employers, this reality necessitates extended mentorship periods and structured field training to ensure safety and operational accuracy before new hires are entrusted with critical tasks.

What to watch

The immediate next step involves translating survey findings into actionable partnerships. With 96% of manufacturers expressing interest in internships, site exposure, or training collaborations, the industry is signaling a clear demand for structured integration between educational institutions and operational sites. This high level of interest suggests that manufacturers are ready to invest in early-stage talent pipelines, moving beyond reactive hiring to proactive skill development. Such mechanisms allow students to gain practical familiarity with equipment and safety protocols before entering the workforce, potentially reducing the retraining burden discussed earlier.

Raj Prabhu emphasized that "Industry and academia need a structured mechanism to collaborate." This statement points to the necessity of formalized frameworks rather than ad-hoc arrangements. Readers should look for announcements of specific partnership models, such as co-designed curricula or guaranteed internship tracks, which could standardize the transfer of technical knowledge. The success of these initiatives will depend on whether they address the specific gaps in grid congestion and practical exposure identified by developers. Monitoring the establishment of these collaborative structures will be key to determining if the productivity timelines for new graduates begin to shorten in the coming years.
