Solar panels cannot be turned off when exposed to light – light is the source of their power. This means that the panels are always live and can potentially cause electrocution during an emergency situation. The only safe and reliable means to ‘switch off’ (de-energise) the system at the source is to block the light received by the solar panels.
FAQ category: SOLAR PANEL SYSTEM BASICS
Why are solar panels systems sometimes called solar PV systems?
PV is an abbreviation of Photovoltaic: Photo = Light, Voltaic = Electricity. The technical term for a solar panel system is a solar photovoltaic system which is commonly abbreviated to solar PV system.
What are the common causes of Solar PV System Faults?
Common reasons for solar PV system damage or faults include:
- Physical Damage
- Vermin Damage
- Weather events such as lightning, hail and water ingression
- Low-quality system components or age-related component degradation
- Poor quality installation practices
For these reasons, it is advised to have your solar PV system serviced annually by a licensed and accredited solar PV system installer or technician.
What is the DC Danger Zone?
The DC Danger Zone refers to the safety risks that solar PV systems pose to Firefighters, First Responders, Electrical Technicians and PV System Owners & Operators.
