* Solar panels generate low voltage DC electricity. While the voltage can be high enough to be dangerous, the current is very low.

* The surface of a solar panel is usually cool to the touch. The heat generated by the panel is dissipated into the environment.

However, there are a few things to keep in mind:

* Solar panels can be hot after being exposed to direct sunlight. This is due to the heat generated by the sun, not the panel itself. It's a good idea to avoid touching a panel after it has been in direct sunlight for a long time, as it could be hot enough to burn you.

* The electrical connections and wiring on the back of a solar panel can be dangerous. Never touch these components, as they are live and can deliver a dangerous shock.

It's always best to err on the side of caution and treat all solar panels with respect. If you need to work on or near a solar panel, make sure you disconnect the power source first and use proper safety precautions.
