In general, the risk of an electric shock from a solar panel is very low. Solar panels produce direct current (DC), which is generally considered less dangerous than alternating current (AC) when it comes to electric shocks.

Most solar panel systems are designed to be safe for installation and use. However, there are some important safety practices that should be followed:

1. Installation by professionals: Have solar panels installed by qualified professionals. They have the necessary knowledge and experience to install the system correctly and follow safety standards.

2. Power disconnection: During maintenance or repairs, the power to the solar panel system should be turned off. This is usually done using switches or shut-off mechanisms.

3. Adhere to warning labels: Solar panels often come with warning labels and instructions. It is important to read and follow these.

4. Safe distance: Avoid direct contact with the wiring and connections of the solar panel system. Maintain a safe distance if you are not a qualified technician.

5. Be aware of inverters: In some cases, inverters (which convert direct current to alternating current) can have higher voltages. Be aware of their location and follow safety guidelines.

In short, while electricity should always be taken seriously, solar panels are generally safe to use. However, it is essential to maintain caution and safety standards, especially during installation, maintenance, or any repairs.
