No. To reduce the DC electricity produced by the solar PV system to safe levels, only 40% coverage of each solar panel is required. However, we always recommend 100% coverage as a ‘best practice’ procedure.
FAQ category: APPLICATION And Usage
How long does PVSTOP take to switch off my Solar Panel system?
PVStop ‘switches off’ a solar panel system in a matter of seconds. Once the coating has been applied across 40% of the solar panel array, the solar array is electrically safe. Please refer to the Demonstration Video on our website for a full explanation.
Does PVSTOP work in all weather conditions? Can it be applied in rain or wet conditions?
Yes, PVSTOP works in all weather conditions, even in rain and on wet solar panels. In extremely heavy rain, there may be some surface run-off requiring a second application to ensure adequate coverage.
What is the delivery distance of PVSTOP?
A PVSTOP cannister can spray up to 10 metres (30 feet) in ideal conditions.
What delivery systems are used to apply PVSTOP?
PVSTOP utilises a portable pressure vessel the design and manufacture of which complies with local fire extinguisher standards.
In 2024 PVSTOP is launching a drone delivery system, ideal for high-rise, dangerous to access and large-scale applications.
Is PVStop easy to apply?
Yes. The PVSTOP delivery system is similar to a fire extinguisher – point and spray. A 9 litre (2.5 gallon) cannister can discharge in 70 seconds and a 4.5 litre cannister can discharge in 35 seconds
Does PVSTOP peel off all surfaces?
No, PVSTOP will easily peel off any smooth surfaces (such as solar panels), but it can be difficult to remove from porous surfaces. Porous surfaces will require a high-pressure water spray to remove the PVSTOP coating.
What should I do if PVSTOP accidentally gets on surfaces other than solar panels?
For porous surfaces, immediately wash with water. Once dry, PVSTOP is difficult to remove from these surfaces. For non-porous surfaces, allow to dry then peel off. A high-pressure water spray may assist if removal is challenging. Avoid contact with clothing or PPE, as removal is extremely difficult once dry.
What happens if PVSTOP is applied to turnout gear or clothing?
PVSTOP is extremely difficult to remove from clothing once dry. Avoid getting the coating or coating overspray onto clothing or turnout gear.
Is PVSTOP effective at night or in low-light conditions?
While primarily designed for daylight use, applying PVSTOP at night or in low-light conditions is a proactive safety measure. It ensures the system remains de-energized when light returns, which is crucial in post-incident scenarios or when preparing for potential daytime risks.
