Nobody builds solar farms on "north-facing slopes". Nobody is making solar panels "track the sun". Nobody even proposes "clearcutting forests" for solar farms. Trolling is in strict violation of site guidelines.
It's very common for utility-scale solar to use single-axis trackers (the panels move from pointing east to pointing west through the day), unlike small-scale solar which usually has fixed panels (normally pointing south or north depending on which hemisphere you're on). The gain from single-axis trackers is high enough and their cost is low enough (a single geared motor can move a whole row of panels) to make it cost-effective.
(I haven't, so far, seen any large photovoltaic solar power plant which uses two-axis trackers to really track the sun; but thermal solar power plants with a central tower need these two-axis trackers to aim each mirror at the correct angle.)
If those solar panels replace a coal fired power plant, is that still true? I am unsure.
"But there are also other ways to boost the energy production of solar panels – such as by tilting them to follow the Sun's path in the sky, similar to the way young sunflowers follow the sun from east to west during the day. Tracking technology, which is already in use on some land based solar arrays, helps increase the overall electricity production, as the panels constantly adjust to face the Sun."
