Intuitive operation, intelligent automated processes and an app that gives you an overview. Sell locally generated green power to local customers with ease.

Tailor-made for your project

In close cooperation with you and the responsible authorities, we develop measurement concepts that are precisely tailored to local conditions. If desired, we also coordinate the implementation including all registrations and service providers.


Scalable & automated operation of your customer system

For any number of properties and tenants, billing of electricity consumption is automated, audit-proof and takes into account current regulatory requirements. Invoicing is also automated via e-mail.

Easy integration with your systems

Using APIs, you can easily transfer captured data between different systems in an automated way.
Integration with your accounting or ERP system is also seamless and secure. You can access your data at any time and keep it up to date via our interfaces.


Flexible residual electricity billing

PV electricity only, mixed price or different tariffs for different electricity sources? No problem!
A two-price system for solar and grid electricity, including the optional connection of spot market tariffs, can be implemented without any problems and enables flexibility in residual electricity billing.

What our customers appreciate about working with Solarize

PV Contractor

"We wanted to make our customers an attractive offer for PV & residual power at spot tariff - without causing high manual effort in billing. Solarize's software allowed us to solve both: Our customers appreciate the flexibility in the two-price system and we have massively reduced our billing effort. Also, we have minimized the risk for residual power purchases."

"Our desire to open up a new business model with the topic of "decentralized energy supply" quickly became a reality with Solarize.
It is a good feeling to have experts with deep expertise at our side and to know that we do not have to continuously keep ourselves informed about changing framework conditions."

Projektentwicklung GmbH

PV contractor

"Solarize enables us to sell locally produced electricity and residual electricity to customers at different prices based on consumption. This reduces our risk and allows us to offer transparent and fair prices. We were also convinced by the possibility of using a virtual meters and thus offering tenant electricity in a scalable way."

Microgrid management? Solved!

The advantages of tenant electricity at a glance 


Higher yields from the PV system

Thanks to EU regulation, there are no transport and grid fees for electricity consumed on site. By marketing on-site, this significantly improves the yield of your system compared to full feed-in.


Cheaper energy costs for tenants

Electricity without transportation costs is generally cheaper than grid electricity. Local use of electricity produced on site noticeably reduces energy costs for tenants.


Sustainable and eco-friendly

By managing roofs for tenant electricity from photovoltaic systems, you make properties more sustainable, reduce CO2 emissions, and create incentives for climate-conscious actions.


Greater independence

By purchasing electricity on site, tenants are less affected by external fluctuations in electricity prices.


Increasing the value of the property

PV systems are attractive investments that contribute to increasing the value of the property. Especially if previously unused areas such as roofs, parking lots or open spaces are used for the installation.
