A full Photovoltaic System is a large capital investment, but we can start by installing a proper foundation Battery Backup System with either Lithium Batteries or Gel Batteries, ready to accept panels later.
This is wired into your DB and connected to all your essential items using all the correctly sized cables and connections in anticipation of expansion.
This system we size correctly in anticipation of receiving the panels later.
This allows you to overcome the inconvenience of load-shedding and gets you one step closer to having a full Photovoltaic System when you are ready, by merely adding panels.
You can get cheap battery systems installed, but this will not sustain the addition of panels later.
