One partner for your whole energy system
Ultima Energy designs, supplies, installs, permits, maintains and monitors solar, storage, heat pump and EV charging systems for households, businesses and farmers.
Every technology, in one system
What makes us different is that we combine all these technologies into one integrated system. Heating and cooling with heat pumps, solar generation, battery storage and vehicle charging are designed together, in one study, and controlled from one app.
Our team of engineers and technicians takes the project from start to finish, including the whole permitting process, step by step. After handover we monitor performance remotely and carry out maintenance, so the system performs as designed.
Study
Electrical and heating loads, shading, sizing.
Supply
Equipment from leading manufacturers.
Installation & permitting
By our own crews, supervised by an engineer.
Maintenance & monitoring
Remotely through the app, plus site visits.

- Site survey & study
We measure the space and shading, review your bills and heating loads, and size the whole system.
- Permitting
We handle the whole process step by step: the HEDNO (ΔΕΔΔΗΕ) application, paperwork and net billing contracts.
- Supply
GoodWe, GoodHeat, Huawei and Deye equipment, chosen for your own study.
- Installation
Solar panels, batteries, heat pumps and chargers fitted by our own crews, supervised by an engineer.
- Connection & setup
Grid activation, inverter and app setup, and training on how to use it.
- Monitoring & maintenance
We track performance remotely and carry out scheduled maintenance and repairs.
We help with the cost too
Bank financing
We prepare the application for a green home loan or business loan, so the repayments are covered by your savings.
Battery subsidy
The Ministry of Environment and Energy is preparing a new support scheme for storage, worth 200 million € in total, with calls opening by the end of 2026.
Balcony solar
The new self-consumption framework announced on 14/9/2026 allows systems of up to 800 W. The process to permit their use is under way.
«Φωτοβολταϊκά στη Στέγη» (Solar on the Roof) & «Κινούμαι Ηλεκτρικά 3» (Electric Mobility 3)
No new applications are being accepted. We'll let you know as soon as a new programme opens.
