Tepto Integration in Eturnity: One Workflow for the Entire PV Process

For solar installers looking to remain competitive today, one question is impossible to avoid: How can the journey from initial planning to final order be shortened without compromising on quality or margins? This is exactly where the new Tepto integration in Eturnity comes in. Planning, structural engineering, costing, and procurement are brought together in one seamless digital process — with no copy-paste and no duplicate data entry.

For the PV industry in Germany, this is more than just a practical addition. It addresses a problem many solar installers face in their daily work: switching between planning software, structural engineering tools, and ordering processes takes time, increases the risk of errors, and ultimately eats into margins.

Who is Tepto?

Tepto is a German PV wholesaler and system supplier specializing in professional solar installers. Its portfolio covers both residential and commercial PV systems and brings together numerous leading brands under one roof. In addition to broad product availability, Tepto offers direct access to components, fast logistics, and reliable spare parts supply — factors that increasingly determine project timelines when sourcing photovoltaic components.

How does the new workflow work in practice?

The integration directly connects Eturnity as a PV planning software with Tepto’s product data and ordering system. All relevant information is automatically brought together and kept synchronized throughout the entire process, from the initial system design to the final order.

1. Automatic synchronization of the Tepto catalog
The complete Tepto product catalog is continuously updated in Eturnity:

• All components are immediately available for PV planning
• No manual maintenance of product data required
• Always up-to-date availability and technical specifications

2. Automatic compatibility check
During system planning, Eturnity automatically checks the compatibility of the selected components, particularly when sizing inverters, which is one of the most common sources of errors in PV system design. Incompatible configurations are identified immediately, before they become an issue in the quote or on the construction site.

3. Real-time individual purchase prices
Eturnity automatically synchronizes customer-specific Tepto purchase prices. This means that calculations, quotes, and profitability analyses are consistently based on realistic, up-to-date pricing. This provides the foundation for accurate margin calculations and reliable quotes for end customers.

4. Structural engineering through K2 Base
The planning data is automatically transferred to K2 Base for structural engineering calculations. The completed bill of materials (BOM) is then transferred directly back to Eturnity — with no duplicate data entry and no transfer errors that can occur when manually exchanging data between tools.

5. Ordering through the Tepto partner webshop
At the end of the process, the complete bill of materials is transferred directly to the Tepto partner webshop (partner.tepto.de). The order can then be completed in just a few clicks, without having to enter the data again.

What impact does this have on the daily work of solar installers?

A seamless digital workflow doesn’t just change individual steps — it transforms the overall structure of day-to-day project work:

• Less time spent on planning and quote creation
• No media discontinuities thanks to directly connected systems
• Greater planning certainty through automatic compatibility checks
• Error-free bills of materials thanks to seamless K2 integration
• Faster procurement through Tepto without data loss at system interfaces
• Consistently up-to-date calculation basis thanks to synchronized purchase prices

Ultimately, this means less administrative work, more time for actual project work, and a more reliable calculation basis for every individual quote.
