The Customer

Learn more about Engesolar

Engesolar, part of the ENGESER Group, provides end-to-end DC cabling solutions for utility-scale solar projects. Based in Germany, the company combines automated cable manufacturing, detailed engineering, and installation-ready solutions to help EPCs and developers deliver photovoltaic projects faster, with greater precision and higher installation quality.

Challenges

Reducing complexity in DC cable design

Traditional DC wiring in ground-mounted solar plants, which involves connecting individual PV strings with separate cables, presented several critical challenges for Engesolar and their clients.

Time-consuming manual quoting

Calculating string lengths from PDF files for project quotes was a manual, hours-long bottleneck.

High risk of errors

The manual nature of this process increased the likelihood of mistakes such as incorrect cable lengths, improper connections, and inconsistent quality control.

Lack of integrated design capability

As a new entrant into solar design, Engesolar needed a robust and intuitive tool to efficiently plan ground-mounted parks.

”If we receive the string plan as a PDF, it takes hours to generate the quote because we must manually calculate each string length.”

The solution

Replacing manual cable planning with a digital workflow

Engesolar adopted PVcase Ground Mount and Harness Manager to transform how it designs DC wiring for utility-scale solar projects. Together, they provide a single workflow for planning ground-mounted PV systems and creating installation-ready cable harnesses, enabling Engesolar to expand its engineering capabilities while delivering faster, more accurate designs.

Optimize DC wiring design

PVcase Ground Mount became the foundation of Engesolar's design workflow, automating the planning and optimization of DC string harnesses. Engineers can create detailed, installation-ready cable layouts faster and with greater accuracy.

Design realistic cable harnesses

Harness Manager overcomes the limitations of traditional harness planning by accounting for real-world installation scenarios. Engesolar can incorporate detailed cable harnesses directly into ground-mounted PV designs with greater precision and confidence.

Build in-house design capabilities

As a new entrant to solar design, Engesolar adopted PVcase Ground Mount to establish an efficient in-house design workflow. Its intuitive interface and fast onboarding enabled the team to quickly expand their engineering capabilities.

”With PVcase, we generate quote in just 5 minutes, significantly saving time and eliminating human errors.”

Results

Turning smarter DC wiring into measurable results

By connecting design, cable planning, and quoting in a single workflow, ENGESOLAR reduced engineering effort, optimized material usage, and expanded the value it delivers to customers.

Save €50k–100k in copper costs

PVcase's precise string length and voltage drop calculations help ENGESOLAR optimize conductor sizing without compromising performance. On a 100 MW project, this reduced copper costs by €50,000–100,000 by using 20–25% of 4 mm² cable instead of 6 mm², while keeping voltage drop below 1%.

Half a day → 5-minute quotes

With PVcase-generated DWG files, project quotes that once took half a day can now be completed in as little as five minutes, enabling ENGESOLAR to respond to customers significantly faster.

Become a 360° DC wiring provider

PVcase enabled Engesolar to expand beyond cable supply into complete DC wiring planning and pre-assembly services, strengthening its position as a full-service partner for utility-scale solar projects.

Deliver greater value to every project

By combining design expertise with measurable material savings, Engesolar enables developers and EPCs to reduce costs while building stronger, long-term customer relationships.
