Four services, in the order they are needed. You can come in at any point, but skipping the first is the most common way of paying twice.
Solar or wind resource on the actual site, planning and landscape constraints, available grid connection, estimated yield and self-consumption share. This is the study that says whether it is worth it, and on what terms.
Plant sizing, electrical schematics, component selection, and complete documentation for permitting and grid connection. The design is written for whoever has to install it and whoever has to maintain it.
Storage sized on measured load profiles, not on typical ones. Control logic, integration with generation and with the loads that must stay powered even when the grid is down.
Metering and software to compare real output against the design. A deviation, if you can see it, is a fault or a calibration: if you do not measure it, it is just a higher bill.
Revera® Energy handles design and works supervision. Installation is carried out by the contractor, who remains responsible for execution: our job is to verify that what gets built matches the design. We do not sell plants, we do not generate energy, and we do not supply it.
The same method across all four services: we start from site and consumption data, not from a catalogue of solutions.
Site and real consumption data: irradiation or wind, load profiles, constraints, the state of the grid connection.
Sizing and documentation, with the assumptions stated and the margins written down.
Once the plant is running, expected output against measured output, until the two numbers agree.
The feasibility study is where it starts.
