Big Dog Solar is a U.S.-based solar EPC (Engineering, Procurement, and Construction) company that designs, installs, and delivers residential and commercial solar energy systems. Their operations span the entire project lifecycle, from engineering and planning through installation, requiring close coordination between design, electrical, structural, and field teams to deliver safe, high-quality solar projects.

As Big Dog Solar continued growing, maintaining quality across an increasing number of projects became more challenging. Every solar installation relies on accurate electrical and structural plans, and even small design errors could lead to costly revisions, installation delays, or additional work for electricians on-site.

The company needed experienced operational support that could strengthen quality control before projects reached construction, ensuring every installation package was accurate, practical, and ready to build.

Eterna initially partnered with Big Dog Solar to provide operational support and improve project quality. Over time, the partnership expanded significantly, with more than ten Eterna team members now supporting multiple departments across the business.

Strengthening Quality Before Installation

Eterna's specialists review electrical interconnection methods, structural information, and technical plansets before projects move into installation, identifying issues while they're still inexpensive and easy to fix.

Practical Electrical & Structural Reviews

Rather than simply checking for errors, the team evaluates each project from the perspective of the field electricians—selecting the most suitable interconnection methods, recommending improvements, and ensuring installations can be completed efficiently.

Faster Collaboration Across Teams

When revisions are required, Eterna works closely with Big Dog Solar's drafting and operations teams to communicate changes quickly, minimizing unnecessary back-and-forth and helping projects stay on schedule.

Today, Eterna has become an integrated extension of Big Dog Solar's operations. By adding an additional layer of technical review before installation, the team helps reduce preventable mistakes, improve project quality, and make installations more practical for crews in the field.

The partnership has also expanded well beyond its original scope, with Eterna supporting multiple operational functions across the company as Big Dog Solar continues to grow.
