p><strong>Mounting solar panels on a roof</strong> should only be done if you have sufficient space of course, but also if the roof orientation is right for solar exposure. An alternative, as you mention in your question, is a<strong> solar tracker mount</strong>. We have an article on that very topic, see here –</p> <p><strong><a href="/guides/3220/choosing-a-solar-tracker-or-fixed-solar-mount/" target="_blank">Choosing between solar trackers and fixed solar panels mounts</a></strong></p> <p>It can be more expensive on one hand to install a solar panel tracker, but you do save money by purchasing less panels since the tracker keeps the panels pointed directly at the sun so you will get greater yield from less panels. You’ll see the pros and cons in that article, let us know if it doesn’t answer all your questions.</p
