To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average. However some manufacturers have recognised the need for compact panels which are ideal for households with small roofs.

For a 10 kw system size using low efficiency panels your system will occupy around 612 sq ft. For the most accurate and personalized off grid system size calculation call our solar experts at 1 800 472 1142. We want to help you get the system that s right for you. 6 2 kwh x 1000 convert to watts 6200 watts solar panel required.
