Collecting Rain - 80 Sq/m roof collecting rain water. 30,000 L water tank is almost always filled.
Land - 4000 Sq/m land can be used for planting fruits and vegetables or for cow and sheep food and animals playground
Wind Generator - apart from 2.6 KW solar panels, 8 KW wind turbine charging the batteries
Water Calculation - this is the formula:
Litre of rain water collected a year = Roof Area (sq m) x Rainfall (mm) x 0.9
Rainfall in this area is a bit more than 1000 mm a year
80 x 1000 x 0.9 = 72,000 L / a year (that is a lot of free water)
