Don't be afraid. Depending on the structure, the panels are attached in different ways. Some use pressure blocks, and others are attached directly to brackets. The brackets are driven into the concrete roof structure using expansion bolts. The load capacity and wind resistance are very strong. Solar energy is a renewable energy source. It refers to the radiant thermal energy of the sun (see the three modes of propagation of thermal energy: radiation), and its main manifestation is often called solar rays.
There are advantages and disadvantages.
1. Advantages of installing solar panels on the roof:
1. If solar power generation panels are installed on the roof, solar energy resources can be used efficiently. It can generate electricity, which can save electricity. Nowadays,the State provides subsidies for the installation of electricity production panels. Thanks to solar energy production, the usual electricity consumption will be less, saving money on your home's electricity bill.
2. Installing solar panels on the roof is relatively simple. Generally speaking, a few workers can install them in half a day.
2. Disadvantages of installing solar panels on the roof:
1. The investment in installing solar panels is relatively large. For some families, this may factor in the cost of installation. the price will be high and they will not accept it.
2. This type of solar energy production panel is installed directly on the roof. It may be exposed to wind and sun for a long time and cause corrosion problems.
3. After all, solar panels are obtained fromr solar energy. Only by using solar energy can we generate electricity, so they can only be used on sunny days, if it is cloudy or if it is sunny. the sun is not particularly bright, electricity consumption will be affected.
4. During installation, holes must be drilled on the roof to penetrate the roof. Unreasonable installation at a later stage will cause roof leakage problems.
