Till börja med behöver vi definiera vad vi menar med "off-grid". "Off-grid" syftar till byggnader eller platser som inte ansluter till det nationella elnätet, vilket innebär att de är självförsörjande när det gäller elproduktion. Off-grid system kan vara ett idealiskt val för avlägsna platser, där det kan vara kostsamt ...
