Most of you may have learned that the earth is not flat. Which is too bad, really. If it was flat, we’d just place PV panels all over it and call it a day. Our Mounting Guide would certainly be a lot less interesting.
But no, of course it isn’t flat. It’s not even round, really. It’s hilly and bumpy and slanted and hard and soft. It’s also full of wind and falling water and ice. And sometimes, when the gods are bored, the ground literally quakes. And that’s just on one site.
Somehow, on top of all that, we are now installing GWs of renewable energy. How is it even possible? Why, mounting and racking solutions, certainly help. Below is a guide to many of today’s top mounting/racking companies, the services they offer and a standout product in their lineup.
