Panel rotating mechanism allows us to easily change the angle (tilt) of all 354 panels at once. The weight of 354 panels is more than 3 tons, so it's a big deal.
Until now we were able to move the panels with a lever, but that recently changed to a winch. So what's the difference between a lever and a winch? Winch is even easier to move - turning a winch requires very little physical strength. ...And winch somehow looks more sophisticated...

We had this panel rotating mechanism installed by our friend Matsuoka-san and his company SOLAR CULTURE.
