Before you order
Frequently asked questions
Short answers to the questions that come up most often when you choose PV equipment.
Do you deliver panels, inverters and batteries across Romania?
Yes. We sell and deliver equipment across Romania. For bulky products or complete configurations, we discuss the order and delivery details before dispatch.
How do I know whether the product is compatible with my system?
Compatibility depends on voltage, power, communication and system architecture. Use the configurator as a starting point and contact us before ordering if you already have an inverter, a battery or a list of components.
Do you also offer installation?
Installation is available for projects in Transylvania, depending on the address and the specifics of the job. Equipment sales and delivery are available nationwide.
How do I choose the right power or capacity?
The choice starts from your consumption, the type of installation, the available area and the goal of the project. The configurator helps you build the basis, and we can review the result together before you order.
