DC certainly has a few more ways it can be dangerous at the same voltages. The biggest issue is electrical arcing. DC can strike up and hold an arc far easier than AC. And because of this, most areas are also now requiring DC solar arrays to have arc fault protection now as well.
DC protection in photovoltaics safeguards the installation from overvoltage, overloads, and short circuits on the direct current (DC) side, which can occur due to lightning strikes. This prevents damage to panels and the inverter while minimizing the risk of fire. 2. What is the purpose of AC protection in photovoltaics?
Adequate protection of photovoltaic panels, tailored to their characteristics, is a key factor ensuring their long-term and safe operation under environmental conditions. Properly selected and installed protections safeguard the system from overvoltage, overloads, and other risks that may lead to severe failures.
Lightning, ground faults and line surges can produce high voltages even in low voltage installations due to the wiring and DC to AC inversion rates of Solar PV systems. Since they are built in exterior settings, most will experience lightning or storm conditions at some point.
The voltage output of a single solar cell under Standard Test Conditions (STC) is approximately 0.5 volts. To increase the overall voltage, these cells are connected in series within a solar panel. Solar panels generate Direct Current (DC) power, whereas most household appliances operate on Alternating Current (AC) power.
The safest array for grid-tied or off-grid systems can still feature high voltages. While high voltage represents an electrocution hazard, DC high voltage is not as dangerous as AC high voltage. Considering this, we recommend using a solar array configuration with the highest string voltage up to 120VDC if safety is your main concern.
