Heiwit Token: 1 Year of Shared Energy with the Photovoltaic Cloud

Heiwit Token: First Anniversary of the Photovoltaic Cloud

Today we celebrate the first anniversary of Heiwit Tokens, the service that enables individuals and companies to participate in renewable energy production in a simple, transparent and scalable way. In just one year we have proven that the cloud photovoltaics can generate concrete benefits: for the environment, for people and for the economy.

How the service works

Token = plant quota: Each Heiwit token represents a portion of the installed power of a real, monitored photovoltaic system.
With tokens, you can increase or decrease your quota over time, without size or location constraints.

Measured production, automatic allocation: the plant's electrical production is continuously measured;
the total energy is distributed among the tokens and thus among the customers. The accounting is pro-rata and transparent.

Dashboard and reporting: we offer clear reporting of energy produced, estimated cost savings and environmental impact
(CO₂ avoided). Everything is viewable and downloadable for your internal needs.

Flexibility and scalability: you can start with just a few tokens and grow progressively. The cloud model eliminates technical complexities and barriers to entry: no permits, available roofs or construction sites to manage.

Year 1: the results of the implantation

Total production
61,831.5 kWh
12 months
Average production per token
103.05 kWh
per token/year
CO₂ avoided
29,679.12 kg
(0.48 kg per kWh)

Savings in utility bills: estimation

The savings depend on the energy price you are paying. Here are three example scenarios:

Energy price Total savings/year
0.30 €/kWh 18.549,45 €
0.45 €/kWh 27.824,17 €
0.60 €/kWh 37.098,90 €

Note: values are estimates based on the year's production and assumed prices; your actual savings will depend on your contract and consumption.

Our innovations: because sodium also counts

Heiwit sodium ion batteries: we have firmly embraced sodium-ion (Na-ion) technology as a strategic alternative to traditional storage. Compared to many lithium solutions, Na-ion guarantees:
increased intrinsic safety, good performance over large thermal window, more abundant materials and potentially more stable costs in the medium term. They are a key lever to scale storage without compromising sustainability and reliability.

Thanks to our customer community

This first milestone is as much yours as it is ours. Thank you for your trust, ideas and energy.

We will continue to design better performing plants, develop integrations with storage systems and improve
the platform, with a clear objective: making clean energy accessible and affordable for all.

Together, we are accelerating the energy transition.
