nettiomavaraisuusjärjestelmien

Nettiomavaraisuusjärjestelmät, often translated as "net self-sufficiency systems" or "net energy self-sufficiency systems," refer to arrangements where individuals, households, or businesses aim to generate enough renewable energy to meet their own consumption needs, potentially selling any surplus back to the grid. The primary goal is to reduce reliance on external energy providers and minimize the carbon footprint.

These systems typically involve the installation of renewable energy sources, most commonly solar photovoltaic panels, on the property. The generated electricity is first used to power the household or business's appliances and equipment. If the generation exceeds immediate demand, the surplus electricity can be fed back into the public electricity grid, often under specific compensation schemes. Conversely, when generation is insufficient to meet demand, electricity is drawn from the grid.

The concept of net self-sufficiency emphasizes the "net" aspect, acknowledging that complete independence from the grid might be impractical or uneconomical due to intermittent nature of renewable sources. Instead, it focuses on balancing energy production and consumption over a period, often a year. Key components include the renewable energy generation technology, energy storage solutions like batteries (though not always mandatory), and a smart metering system that tracks both energy fed into and drawn from the grid. Regulations and incentives vary significantly by region, influencing the economic viability and adoption rates of these systems.
