With Decree - Law no. 153/2014, it became legally possible for individuals or entities to produce their own energy, being connected to the electricity grid.
UPAC - Self-consumption production unit
The energy produced is consumed locally, being the produced energy saved from the public grid. With the extraordinary price reduction of solar photovoltaic technology in the last 5 years, this form of energy has become cheaper than the public grid. Therefore, in addition to the emissions of pollutants and CO2 avoided, the time of return is extremely low, generally less than 5 years,
In the graphic, can observe an example of savings (with a well-sized self-consumption system with little surplus).
All the energy produced is injected into the home network. For example, if consumptions are 1000w, and the solar system is producing 700w, it will only consume 300w of the grid, a considerable saving.
We have small ready-to-assemble kits, and we also dimension and install larger systems for bigger consumption.
Self-consumption system consists of:
Photovoltaic modules: produce DC energy
Grid Inverter: converts DC to AC single or three-phase
Production meter: required for more than 1500w
