The only way you can get shocked is if you are touching both the positive and negative conductors at the same time, as neither has a path to ground to complete a circuit. Also, the conductive parts of a MC4 connector are recessed and difficult to touch.
Electric shock stands out as a serious threat due to working with live wiring and electrical components. Weather conditions like wind and rain further increase these hazards by reducing stability and visibility. Poorly secured panels can fall, causing injury or property damage.
A 3V solar panel refers to a photovoltaic device designed to convert sunlight into electrical energy with a nominal output voltage of approximately 3 volts.
Solar panels, unless heavily shaded have a remarkably high and consistent voltage output even as the intensity of the sun changes. Panel temperature will affect voltage - as has been discussed.

Yes, you can absolutely run an electric heater using solar panels! While a single panel might not be enough for a large heater, a well-designed solar system can generate enough power to keep you warm and cozy, even in colder months.
The charging voltage is the amount of energy flowing from the solar panels to the battery. To set it, you must first know the battery's nominal voltage.
This is a DC power meter (aka watt meter): You can find them for cheap on Amazon. Connect one inline between your solar panel and charge controller and it'll measure voltage, current, wattage, and more.
Unlike lower-capacity modules like 6V panels with 5. 5V output ranges, 270W commercial-grade units typically operate at 30-40V open-circuit voltage. Modern 270W panels must exceed IEC 61215 mechanical load requirements, withstanding 5400Pa front-side pressure and 2400Pa back-side.
