What Reonic is
Reonic GmbH in Augsburg makes a platform for installation companies working with solar PV, batteries, EV chargers and heat pumps. It covers CRM, 3D planning, simulation, quotes with e-signature, an installation app and invoicing. According to Reonic, more than 3,000 companies in over 30 countries use the platform.
Planning is based on Google’s solar mesh and orthophotos from Apple, Google and Bing, and a 3D model can be built from your own drone images. Yield is calculated with Reonic’s own model, which Reonic has validated against PVGIS. The website is available in Swedish.

| Battery | Battery sizing tests every size hour by hour; control by hourly price in SE1–SE4 | Battery, EV and heat pump; flexible tariffs, e.g. Tibber |
| For the customer | PDF report in A4 at three levels, with a 3D view, strings, yield, shading and economics | Quote as PDF or digital with e-signature; CRM and installation app |
| Interface | Swedish, English and German | The language can be changed; which languages is not stated |
| Price | Designer at no cost; Pro €49 per user per month excl. VAT, with volume discount (pre-order) | No list price (on request) |
The details on Reonic come from the vendor’s own pages and were checked on 14 November 2026; the sources are listed at the end of the page. "Not stated" means the detail could not be verified there. The Ritwerk column describes the designer as it is today.
When Reonic is the better fit
When the company wants the whole chain in one system: enquiry, planning, quote, e-signature, installation and invoice. Reonic also calculates heat pumps and EVs, with flexible electricity contracts such as Tibber as an example, and includes German subsidies such as KfW and BAFA in the profitability calculation.
The component database covers modules, inverters, batteries, EV chargers and heat pumps, and you can upload your own datasheets. In Germany, Reonic also offers grid registration as a service.
When Ritwerk is the better fit
When the design has to be worked through electrically and mechanically before the proposal goes to the customer. The designer checks every string against the inverter datasheet – Voc at −25 °C against the maximum input voltage, Vmp at 70 °C against the MPPT window and the current per input – and explains the choice MPPT by MPPT.
The mounting is calculated for snow and wind loads to BFS 2024:6, with fixings per panel and the largest c/c spacing. Ritwerk suits companies that already have a CRM or quoting system and need a design tool alongside it, with no account and nothing to install.
The string plan
Each string gets its own colour on the panels, with the routing along the roof and the check per string. The same string plan appears at the Full level of the PDF report, with the table of string voltages.

Questions and answers
Questions and answers
What does Reonic cost?
Reonic gives no list price for the platform and asks you to get in touch. As a service in Germany, Reonic offers grid registration for €349 excluding VAT per PV system.
Which languages is Reonic available in?
Reonic’s website is available in Swedish, among others. According to Reonic’s documentation, the interface language can be changed, but which languages are available is not stated.
Does Reonic calculate snow and wind loads?
It is not stated in the Reonic product pages or documentation that we read on 14 November 2026.
Can Ritwerk work with the customer’s hourly readings?
Yes. In step 2 you upload the customer’s consumption as CSV, and the designer calculates yield against consumption hour by hour over a full year.
