After a long wait and having the solar equipment in storage for about the last 4 months, we finally got to installing the solar panels. Before installing the panels, we needed to get the roof painted with a fresh coat of roof paint, and fix any loose corrugated iron section and fix holes etc.
First step was getting the solar panels up onto the roof ready for installation. There are 4 x 255w Trina Solar Panels.
Next the panels were secured to the roof using aluminium angle iron strips and raw bolts. The positioning of the raw bolts is important, to ensure that they go through the metal roof and into the supporting wooden rafters under the corrugated roof. Washers were used as spacers to level the angle iron as the roof was not entirely flat. Small raw bolts were used to attach the aluminium angle iron strips to the solar panels, which are also made of aluminium around the edges. Aluminium is soft and therefore easy to screw bolts into without requiring pilot holes to be drilled etc.
Below is my bro, hard at work making sure the panels are properly secured.
Next was running the solar panel cables running from the charge controller (the smaller blue box), up through the ceiling, then through plastic trunking and finally up onto the roof. The cables are not yet connected, that will all happen later. The inverter also still needs to be hooked up to the main Eskom power supply. We will be trying to go totally of the grid, however Eskom will there for backup purposes should there be any problems with the solar equipment or we have many days of overcast and rainy days etc. The inverter is a 5K Victron Multiplus 48/5000/70-100. The charge controller is a Victron Blue Sol MPPT150/35 Solar Charge Controller.
The cables then run up to the panels on the roof. Also waiting to be connected to the panels which will happen later when all the wiring is done.
And finally, the boxes of super huge batteries and cables, waiting to be installed at a later stage once all the shelves are built for the batteries. There are 4 large Ritar 12V 260AH Batteries. The Invertor is 48V invertor, so the 4 12 volt batteries will be hooked up in series to make up the 48 volts.
And that’s its for now. We will have another solar post once everything has been hooked and connected. That will be an awesome day!
Thanks to my bro Grant, for all the help with the Solar stuff. We are no experts at this, but we are figuring it all out as we go 🙂
