Three steps to fix the waterproof problem of installing photovoltaic power station on the roof

- Sep 02, 2018 -

Many customers want to install a photovoltaic power station, but they are worried about whether the roof will be damaged and the roof leaks. Let's share how to make waterproof.

Waterproof and heat insulation

With the promotion and popularization of rooftop photovoltaic systems, many owners have a certain understanding of photovoltaic power generation. In addition to energy conservation and environmental protection, investment returns, roof insulation and other issues of concern to everyone, photovoltaic waterproofing is also a problem that many owners attach great importance to. In fact, the roof photovoltaic technology is now quite mature, and the waterproof measures are naturally the basic skills of rooftop photovoltaic power generation.

Waterproofing is divided into three steps:

The first step: drilling the roof, injecting waterproof silicone into and around the hole, and then drilling the bolt to cast the first waterproof line.


Step 2: Cover the surface of the mounting hole with “water without leaking” to form a second guarantee.


The third step: coating the upper layer of the water without leaking the special material for engineering waterproofing, so as to achieve foolproof.
