Solar ballast systems are a way to put solar panels on flat roofs without drilling any holes. They use weight to hold the panels down, which is great for businesses and factories because it keeps the roof from leaking and still lets them get solar power.

Basically, these systems have a support made of aluminum or steel that sits right on the roof. The panels go on angled frames, and then heavy stuff like concrete blocks is put in trays to keep the wind from blowing them away. How much weight you need depends on the wind, how tall the building is, and how the panels are tilted.

The best part is that because you're not drilling, you're not making holes that could leak. So, it's perfect for roofs that already have waterproofing or older buildings where you don't want to mess with the roof. This usually means less maintenance for the owner.

It's important to plan these systems carefully. Engineers figure out how strong the wind is and spread the weight out so it doesn't damage the roof. They also use things like wind deflectors to cut down on how much weight you need.

It's easy to put these systems in. The panels can be lined up with space in between so they don't block each other's sun and are easy to get to for repairs. Plus, a lot of the parts come pre-made, so it's faster to install than other systems. Companies like SIC Solar make these kinds of systems to be quick to install, strong, and work with most solar panels.

The stuff they're made of matters too. Aluminum is used a lot because it doesn't rust and is light. Stainless steel screws make sure everything stays together for a long time. Rubber pads go under the system to keep it from rubbing and damaging the roof.

Even though they're good, you have to make sure the roof can handle the extra weight of the panels and the system, mainly if you get a lot of snow or wind. If it's done right, a solar ballast system is a good way to get solar power on a flat roof without wrecking the building.
