Guide Touching panel negative and positive wires
If you look at a solar panel datasheet and compare the current at maximum power point (Imp) to the short circuit current (Isc) you will notice the short circuit current is not significantly higher than the normal operating current. Therefore there is very little potential for panel damage by simply touching the wires together.
6 Frequently Asked Questions about “Solar panels connected and then burn the load”
Is it a bad idea to leave a solar panel unloaded?
btw, an unloaded panel runs hotter than a loaded pane, so to whatever extent it is heat shortens the life of a silicon based panel, it is better to have a load. OK. Long term, it's a bad idea. These neighbors were worried about leaving the panel unloaded for a few hours/days. From what you're saying, that's not really a problem.
How do solar panels work?
There is voltage in the panels but current requires cables to flow and deliver power to electronics, appliances, motors etc. DC powered devices can be connected directly to a solar panel and run. For AC powered appliances and devices, an inverter like the Renogy 2000W is required to turn DC into AC. That is basically how solar panels work.
Do solar panels have power if the Sun is out?
The panels will always have power when the sun is out, so wait for nightfall to disconnect the system. The larger the solar array, the higher the voltage and power. It is not different from any electrical component so exercise caution. Use a multimeter to check the voltage before attempting to disconnect it.
Do solar panels produce more energy than is consumed?
Solar panels always produce energy when the sun is out. The energy is used to whatever load is connected to the system, but what happens if your panels produce more energy than is consumed? In a grid tied system, excess solar energy is sent to the grid where you can tap into it anytime.
Can you leave solar panels in the sun without a CC?
There are LOTS of rumors out there. One I've heard recently is that you can't leave solar panels in the sun without them connected to a CC or some load. The rumor is that it will damage the panels since the power "has nowhere to go." I have a neighbor out here that is just terrified of having sun on their panels while disconnected from the CC.
Can a solar panel be used if the sun goes down?
Of course when the sun goes down you can no longer use the solar panel power, not unless the energy was stored in a battery bank. The situation is comparable to a battery. A fully charged battery – the Vmaxtanks 125ah AGM is a good example – can power several appliances and devices, but it must be connected to a load.
