Designing a commercial solar system requires more than selecting the right equipment. Installers must determine the correct mix and quantity of products, create an accurate Bill of Materials (BOM), and coordinate with sales and procurement teams—all before a project reaches installation.
Manual planning can be time-consuming and increases the risk of missing components, ordering errors, and costly design revisions.
The Enphase System Builder helps simplify this process by generating an accurate BOM based on a few key project inputs. Available free through the Enphase website, this web-based calculator helps installers move from project planning to customer proposals with greater speed and confidence.
Why BOM accuracy matters in commercial solar
Commercial projects involve multiple products, accessories, and design considerations. Even a small oversight during planning can create delays during procurement or installation.
The Enphase System Builder removes much of the manual effort by recommending the appropriate Enphase products and required accessories based on your project inputs. By taking the guesswork out of what to order, installers can improve proposal accuracy while reducing the likelihood of costly revisions later in the project lifecycle.
How the Enphase System Builder works
Getting started with the Enphase System Builder is straightforward:
- Enter your project details – Provide a few key inputs about your commercial or residential solar project
- Generate a BOM – The System Builder recommends the required Enphase products and accessories based on your project configuration
- Export and move forward – Download the BOM in CSV format along with system summaries and design resources to support quoting, procurement, and project planning
Built for faster, more confident project design
The Enphase System Builder is designed to simplify commercial solar planning while supporting more efficient quoting, procurement, and project development.
Key capabilities include:
- Accurate Enphase Bill of Materials (BOM) recommendations
- Project summary reports with example single-line diagrams and design resources
- CSV export for quoting and purchasing workflows
- Support for both commercial and residential solar projects
- Web-based access with no login required
- Minimal project inputs with fast, accurate reliable output
These capabilities help installers spend less time creating equipment lists and more time focusing on customers, project design, and business growth.
From design to procurement—a connected workflow
A well-prepared BOM supports every stage of a commercial solar project. Sales teams can generate proposals more quickly, procurement teams receive complete equipment lists, and installers have greater confidence that the right products will be available when installation begins.
The ability to export BOMs in CSV format also improves collaboration across sales, design, and procurement teams, helping projects move more efficiently from planning to deployment.
Built to support commercial solar growth
As commercial solar projects continue to grow in scale and complexity, installers need tools that simplify planning without adding complexity.
Whether you're designing your first commercial installation or managing multiple C&I projects, the Enphase System Builder provides a faster, more streamlined approach to system design. Combined with Enphase commercial solutions, engineering resources, and installer support, it helps partners move commercial solar projects forward with greater confidence.
