Different roofs have different methods of installing photovoltaic modules. Common installation methods include additional type, ballast type and concrete base type.

If it is a metal roof, an additional type is generally considered.

Lay the modules directly on the roof. In particular, general metal roofs do not have parapets, and the tiling method has the best windproof effect and is the safest; in addition, metal roofs also have a certain inclination. Although it may not be the best inclination angle for photovoltaic power generation, the cost of transformation brought about by increasing the inclination angle also needs to be considered comprehensively.

UISOLAR has different brackets suitable for metal roofs, such as clamping hooks, SS04 hook, L-feet bracket, etc.

If your roof is tile roof, usually also choose the additional type.

Different from the steel roof , the tile roofs usually use different types of hooks to connect the solar panels to the roofs.

For the concrete roof, it is usually flat, and the common installation methods are ballast type and concrete base type.

In many cases, building owners don’t want to drill holes in the concrete flat roof. On the one hand, they are worried about the strength of the old building, or do not want to change the waterproof performance of the roof. This is the reason for choosing ballast type or concrete base installation.

Since the ballast type is not anchored to the roof, windproof treatment can be considered on the side, especially for concrete roofs without parapets.

UISOLAR’s ballasted mounting bracket will be a good choice for this roof type.

And also, some customer will choose to set a concrete base or put the concrete block on the rooftop and then fix the mounting to the roof top.
