Eturnity Solar Expert

Designing renewable energy systems by hand often leads to calculation errors and requires constant switching between different programs. Eturnity Solar Expert simplifies this process by combining 3D roof layouts, technical energy modeling, and automated financial proposals in one digital workspace.

This cloud-based tool is built for contractors, energy advisers, and project developers that want to win customers faster and spend less time in the field. By combining engineering designs with financial estimates, it connects technical site assessments with the sales process.

What Is Eturnity Solar Expert?

Eturnity Solar Expert is an independent Software-as-a-Service (SaaS) platform designed for solar engineering and system design. It is used by installers, sales teams, and technical designers working with solar arrays, EV charging stations, battery storage, and heat pump integrations.

The software uses remote mapping and 3D modeling to simulate how physical equipment may perform before installation. Developed by Swiss technology company Eturnity AG—which merged with Solar Monkey in 2026—the platform is designed for European energy companies managing residential and commercial projects.

Features

• 3D Layouting and Roof Planning: Creates digital building layouts using high-resolution maps, drone photographs, LiDAR data, or direct GLB file uploads.
• Advanced Energy Simulation: Models system efficiency, shading losses, energy consumption, and expected grid payments over time.
• Automated String and Inverter Design: Configures electrical strings and compatible inverters using manual controls or automated pairing algorithms.
• Multi-Technology Configurations: Supports hybrid systems combining solar panels, battery storage, EV wallboxes, and residential heat pumps.
• Bill of Materials Management: Automatically calculates hardware requirements, labor costs, custom discounts, and installation expenses.
• Customer Proposal Generation: Converts technical designs into customer-facing financial summaries, system visualizations, and PDF proposals.
• Permitting Assistance: Uses localized tools, such as the EF Solar add-on, to prepare authorization and grid connection documents.

How to Use Eturnity Solar Expert

To begin a project, enter the customer’s address to open the available roof imagery. The user can then create a 3D model of the building, define structural restrictions, add roof obstacles, and calculate potential shading losses.

Once the technical layout is complete, the platform configures electrical strings and identifies compatible inverters. Users can then add supporting equipment such as battery storage, heat pumps, or EV charging stations.

After reviewing the automatically generated Bill of Materials, the user can create a financial proposal for the customer and export localized permit or grid connection documents.

What You Can Manage with Eturnity Solar Expert

• 3D Roof Layouts: Create detailed building models using aerial imagery, LiDAR data, drone maps, or GLB files.
• Customer Proposals: Generate professional sales quotes showing equipment placement, grid incentives, system costs, and ROI estimates.
• Bills of Materials: Manage itemized component lists, supplier pricing, labor expenses, discounts, and profit margins.
• Hybrid Infrastructure Projects: Design systems combining solar panels, battery storage, heat pumps, and EV chargers.
• Permit Documentation: Produce pre-filled connection and construction forms formatted for local utilities and regulatory authorities.
