Frequently asked questions
What is the difference between net and gross metering?
In the case of net metering, the electricity generated and consumed within a given billing period is compared. If the system produces more energy than consumption requires, the surplus is fed into the grid and can later be used to offset consumption.
In gross metering, the energy fed into the grid and the energy drawn from the grid are settled separately, moreover on the basis of per-phase measurement. This means that energy fed back into the grid and energy drawn from the grid are settled at different rates.
When is it worth installing an energy storage system?
Energy storage is generally warranted when a solar system regularly generates surplus production that is intended to be used at a later time. In such cases, the storage unit redistributes energy over time, for example from daytime generation to cover evening consumption.
Profitability is most significantly determined by the consumption profile, system size, and billing method.
What is the difference between DC and AC coupled energy storage?
In a DC coupled system, the battery is connected directly to the DC side of the inverter, so the inverter controls both solar generation and energy storage.
In an AC coupled system, the energy storage unit connects to the AC grid with its own control system, operating independently of the solar inverter, and is capable of managing generated energy in systems with multiple inverters.
What is the difference between a symmetric and asymmetric inverter?
In three-phase systems, a symmetric inverter distributes the generated output in equal proportions across the three phases.
An asymmetric inverter, by contrast — within limits defined by the manufacturer — can distribute power flexibly between phases, provided that per-phase consumption metering is connected to the inverter.
Where should a corporate digitalization project begin?
The first step of digitalization is generally the mapping and clarification of processes. It is worth examining how individual processes currently operate, where data is generated, and where efficiency issues exist.
When processes are clearly defined and measurable data on operations is already available, it becomes much easier to determine what technological solution is genuinely needed.
What should be paid attention to during the implementation of a grant project?
The key to the success of grant projects is proper preparation and project planning. It is important that the technical scope, timeline, and eligible costs are precisely defined already at the grant application stage.
During implementation, particular attention must be paid to deadlines, documentation, and compliance with grant conditions.
