Direct importer and distributor
We buy directly from the factory. That is why we know what we install.
We are not just installers. We import panels, inverters, batteries and mounting structures directly from the manufacturers and also sell them to other installation companies across Romania. On your project we install exactly the same equipment.
- 1We buy directly from the factoryWe bring goods in by the container, with no intermediaries. For any warranty issue we deal directly with the manufacturer.
- 2We do not buy second-hand batchesThe market sells cheap batches that other buyers have rejected, that have been downgraded or that come with an unclear warranty. We do not buy them, even though we would earn more on them.
- 3Only brands proven in Germany and FranceWe choose major brands that have sold for years in Europe's most demanding markets and that respond quickly on service.
- 4Other installation companies choose us tooInstallation companies from across Romania source from our warehouse. What we sell to them is what we install for you, so we answer for quality twice.
Goods arrive by truck, straight from the factory

Quality, not low cost
The details that make the difference over 25 years
On installation day every system looks the same. The difference shows in production, in summer and in winter, and in how safely the system runs in the years that follow.
- −0.26 %/°CLower losses in the heatAIKO and LONGi panels have a low temperature coefficient. At 65 °C on the roof they lose about 10% of their output, compared with about 14% for a typical panel.
- Even when cloudyThey produce in low light tooIn the morning, in the evening, in winter or under an overcast sky, the panels keep producing. Less than in full sun, but they do not stop.
- No. 1World leaders in efficiencyAIKO and LONGi jointly top the TaiyangNews world ranking (25% for their top models, October 2026). AIKO held first place alone from 2023. These are exactly the two brands we install.
- 6 mm²Premium cable and Stäubli connectors6 mm² solar cable, not the 4 mm² commonly used, and original Stäubli connectors from Germany, for safety.
- 8,000battery cyclesHinen batteries with a 10-year warranty, compared with 6,000 cycles for many batteries on the market. Premium Hinen inverter, 10-year warranty.
- EngineersOn the electrical sideThe electrical work is done only by our engineers. We import the mounting structure directly and choose it for your roof, with no improvisation.
Every house has its own storyDifferent roofs, orientations, electrical panels and habits: some people do laundry during the day, others in the evening. We size the system for your house and your consumption, not to a standard package.
Our customers quickly learn to gain moreAfter installation, most customers move their large loads to midday on their own, when the panels are producing. We connect the system to the app and show you how to monitor production.
