THE SOLAR SOFTWARE FOR EFFICIENT PHOTOVOLTAIC PROCESSES

The solution to your day-to-day business problems is a tailor-made software for the solar industry: The Eturnity Solar Expert

Get end-to-end control of your business processes with Eturnity's Solar Expert for solar installers and utilities. Bring out the best in your team and handle design, sales and administration of PV projects in a fraction of the time.

Your challenge

High demand, limited capacity and overworked staff

The PV industry is at its limit. The design, sale and implementation of photovoltaic systems requires a lot of time, expertise and project management. Your employees are always working under maximum stress.

OUR SOLUTION - ETURNITY SOLAR EXPERT

Finally, a solar software for the entire process: design, sale and execution

Eturnity Solar Expert expands the capacity of your team and brings order to your projects. With the Solar Expert, you can plan and calculate a complete PV system in 3D in just a few minutes and create the perfect sales documentation at the touch of a button, leaving no questions unanswered. As a team leader, you always have a complete overview of the various projects and the sales pipeline.

01

3D design: Accurate and impressive

Model your customers' building in 3D in just a few minutes and design precisely fitting PV layouts with photorealistic modules. Satellite images or orthophotos provide the basis for this. If available, drone photos or plans can also be imported.


02

With 80% time savings to a fully calculated offer for your customers

Define centrally managed templates and assemblies for your sales team. This means that even less experienced employees can quickly put together high-quality quotations. With the help of these templates and the automatic calculation functions of the Eturnity Solar Expert, all employees can also create complete sales documentation with just a few clicks, leaving no questions unanswered.


03

Fewer queries and higher closing rates: Customer-friendly offers make it possible

The customer-friendly offer in your company's website cannot be beaten for clarity: Yield forecast, fully automatic profitability analysis incl. consideration of subsidies, CO2 savings and pictures of the most important components. This massively reduces queries, makes you more efficient and leads to up to 30% higher success rates.


04

Central library for components, prices and templates

Manage all components, including prices and margins, in our central library. The use of templates and assemblies helps you and your team to accurately produce high quality quotes. Eturnity continuously maintains the latest components (modules, inverters, battery storage) for you with images and technical specifications. All you need to do is use these components. There is even the possibility to activate live price connections to suppliers. This also eliminates the tedious and recurring price management. Use this time for more important things!


05

No compromise on calculation accuracy

Quotations with too many offer items sometimes overwhelm the end customer. Once the project is sold, however, you would like to have a complete parts list at hand for efficient processing (e.g. ordering). So you are in a dilemma between simplicity and accuracy. The Eturnity Solar Expert also solves this problem: Combine items as collective items for the sales documentation with just a few mouse clicks. When the project is approved, the complete parts list is directly available for implementation (e.g. ordering process) without any additional effort.


06

Lean CRM for the solar industry

With the lean CRM functions of the Eturnity Solar Expert, you will no longer miss any important activities. Resubmission and follow-up management becomes child's play, so that your customers feel that they are receiving top advice from you despite your high workload. Define your company-specific sales process and track the sales and implementation cycles of your projects. With the project overview, you can easily and clearly keep track of prospective customers, offers and projects.
