Net Zero Homes

Off Grid Energy Infrastructure

Increased efficiency and output of solar panels & battery storage systems + rising utility costs has lifted demand for off grid homes. MEG offers professionally engineered & compliant designs to take any home off the grid


The MEG Bundle

Using MEG for one of our services is good, using us for the entire project's engineering design & compliance scope of work is better.
