Can your home's photovoltaic power system withstand a hailstorm as big as an egg?

Introduction Can the home photovoltaic power system withstand hailstones as large as eggs? Currently, photovoltaic modules are mainly used outside photovoltaic power generation, and common solar modules currently on the market are used.

Can your home's photovoltaic power system withstand a hailstorm as big as an egg?

At present, photovoltaic modules are mainly used outside photovoltaic power plants, and the traditional solar modules currently on the market use tempered work.

1. Tempered glass is actually a kind of pre-stressed glass. In order to improve the strength of glass, chemical or physical methods are generally used to form compressive stress on the glass surface. is subjected to an external force, it first compensates for the surface stress, thereby increasing the bearing capacity and improving the tensile strength of the glass.

2. Tempered glass has two main advantages

The first is that the strength is several times that of ordinary glass, the bending resistance is 3-5 times that of tempered glass. ordinary glass, and it is shock resistant. The strength is 5-10 times that of ordinary glass, which improves noonly resistance but also security.

Second, its increased bearing capacity improves its fragility. Even if the tempered glass is damaged, it will be broken into small fragments without sharp corners, which greatly reduces the damage to the human body. The rapid cooling and heating resistance of tempered glass is 2-3 times that of ordinary glass. It can generally withstand temperature changes above 150°C and has obvious effects on preventing thermal explosions.

According to the current component standard test (the most commonly used standard in the industry IEC61215), tempered glass test experience, hail impact test requirements: the surface of tempered glass must resist the impact of a 1052 g steel ball from a height. more than 1 meter without being damaged.

In general, the impact performance of crystalline silicon solar modules commonly diavailable in the market for hail protection are trustworthy compared to other materials.
