opraus v2.0

Our (new, much bigger) Solar Array

2) zones of 10) Sunpower 315 panels on a south facing roof with a 45 degree pitch.

This system is rated at 6.3 Kw. [or, enough to supply all the electrical our needs]

Our (old, little) Solar Array

Two 80 watt panels by Sharp. We use them to charge 4 deep cycle batteries, which in turn power the 240 gph filtration pump in our pond.

Example image - aligned to the right

The panels are mounted on a 'Polar' tracker I built from parts. It is controlled by a circuit built by RedRok

With 90% sun, we can run the filter 24/7
