Jena, June 26, 2026 – The city of Jena, together with Thuringian districts, the Universität Erfurt, and the Thuringian Energy and GreenTech Agency (ThEGA), is launching the information campaign “Solar Empowerment 2.0”. The goal of the initiative is to make the entry into self-generated solar power as barrier-free and transparent as possible for homeowners.
- What: Free solar potential analysis for single- and two-family houses
- Campaign: “Solar Empowerment 2.0”
- Actors: Stadt Jena, ThEGA, Universität Erfurt, Thuringian districts
- Benefit: Individual data on investment costs, yield, and CO₂ savings
- Service Portal: www.solarrechner-thueringen.de
Individual Mail for Homeowners in Jena
Starting at the end of June 2026, selected owners of single- and two-family houses in Jena will receive mail with an initial, non-binding assessment of their roof. The letter contains specific calculations regarding the photovoltaic potential of the respective building. This includes estimates of annual electricity generation, expected investment costs, economic efficiency over the operating period, and potential CO₂ savings. The entire offer is completely free of charge and non-binding for the recipients.
Practical Benefits of the Solar Campaign
The practical benefit for owners lies in the quick and reliable orientation aid. Without prior expensive professional planning, homeowners learn directly whether a solar system on their own roof is financially worthwhile. The campaign thus reduces barriers and provides a solid basis for decision-making regarding the energy transition in one’s own home.
The following service offers are available to citizens as part of the campaign:
- Personal information letter: Directly in the mailbox with tailored key figures for your own roof.
- Free solar hotline: Telephone advice for all recipients to clarify open detailed questions directly with experts.
- Thuringian Solar Calculator: Those who do not receive a letter can independently check the suitability of their own roof online at solarrechner-thueringen.de.
- Klimaschutzagentur Jena: Supplementary, personal consultation meetings directly on-site for all interested citizens.
The initiative follows a successful pilot project in Weimar, which has already shown that targeted direct mailings can measurably accelerate the local energy transition. Since Jena is particularly affected as one of the heat hotspots in regional comparison, the expansion of renewable energies and the avoidance of greenhouse gases in the urban area are becoming increasingly important.
🛡️ Prevention & Advice: Tips for Solar Planning
Before homeowners install a photovoltaic system, technical construction aspects should be clarified in addition to purely economic factors. This includes the load-bearing capacity of the roof, the condition of the existing roofing, and the optimal orientation to the sun. ThEGA recommends using the free initial consultation offers before concluding binding contracts with installation companies.
