SOLECTRUS is a free, self-hosted dashboard for monitoring solar production, consumption, battery, and grid data. See features and setup options.
SOLECTRUS is a free, open-source dashboard that gives solar photovoltaic system owners real-time and historical visibility into how much energy they produce, consume, store in a battery, and exchange with the grid, along with automatically calculated cost savings.
The project is created and maintained by German developer Georg Ledermann, with active development since around 2020. It is self-hosted, typically running on a Raspberry Pi or a Linux server, and released under the AGPL-3.0 open-source license.
SOLECTRUS visualizes solar production, household consumption, battery state of charge, and grid import and export in configurable dashboards, and it automatically calculates the financial savings generated by a solar installation over time.
The software integrates with common inverter and energy-monitoring hardware, and it can be deployed using an online configurator that generates a ready-to-use Docker setup, simplifying installation for users comfortable with self-hosting.
SOLECTRUS is free and open source under the AGPL-3.0 license, so there is no subscription fee to download, install, and run it. Users are responsible for their own hosting hardware, such as a Raspberry Pi or small server, and any associated electricity or infrastructure costs.
Because SOLECTRUS is self-hosted rather than a managed SaaS product, there are no tiered subscription plans; the software itself is free, and the only ongoing cost is the infrastructure it runs on.
Yes, SOLECTRUS is free and open source under the AGPL-3.0 license. You only need your own hosting hardware, such as a Raspberry Pi or Linux server.
SOLECTRUS was created and is maintained by German developer Georg Ledermann, with development ongoing since around 2020.
SOLECTRUS is typically self-hosted on a Raspberry Pi or any Linux server capable of running Docker, alongside a time-series database.
Yes, SOLECTRUS can monitor battery state of charge, charge and discharge rates, and overall storage system performance.
Yes, it automatically calculates financial savings and earnings based on self-consumption, battery usage, and grid feed-in.
No, SOLECTRUS is self-hosted software. There is no official managed cloud version from the project itself.
