Solar Panel Safety - Safely De-energise Photovoltaic Panels

We are in the midst of a clean energy revolution driven largely by rising grid electricity prices, government incentive schemes and positive public sentiment toward protecting the future of our planet. The increasing uptake of solar panels and the downward pressure on solar photovoltaic system pricing has led to an unprecedented level of growth in the global solar PV system market, growth that is forecast to increase exponentially in the decades ahead. In line with the exponential growth of the solar industry, there has been a similar growth in the number of fire and emergency related incidents involving solar photovoltaic systems, highlighting several unanticipated safety risks. An article on the “The challenges and risks of solar panel” by Zurich Insurance can be found here.

Solar panels cannot be easily “switched off”. As long as they are exposed to light, the solar panels and the wiring leading down from the panels are continually producing potentially lethal amounts of DC electricity, in professional terms this is known as the DC Danger Zone and up until now there has been no safe or practical way to “switch off” these solar PV (photovoltaic) systems at the source (the solar panel).

A PVSTOP supplied by SolarFire Systems is the only product that quickly and safely isolates the power produced by solar PV systems at the source, the solar panels themselves. PVSTOP coats solar panels like a “liquid tarpaulin”, blocking the light and “switching off” the solar panels in seconds, rendering the solar PV system electrically safe.

PVSTOP is effective on all types of solar PV systems and all types of inverter systems.

PVSTOP is a simple solution to a complicated and technical problem. The PVSTOP coating is applied to solar panels, blocking the light and rendering the solar PV system electrically safe.


The primary function of PVSTOP is to render panels to be electrically safe. The PV module does not need to be entirely covered for the panel to be deactivated. Spraying a line down the middle of the panel, for example, and covering only as much as 40% is enough to interrupt solar power production. However, covering the entire panel will continue to reduce DC voltage to zero and should be the main objective.


The PVSTOP spray delivery system allows users to cover solar panels in a matter of seconds. The fire retardant solution blocks light to the PV cells upon application.


The polymer film is designed to stick to solar panels during all weather conditions. Even if the PV modules are wet the coating will stick to the glass panel


Once the coating has dried, PVSTOP can be easily peeled off by hand when it is time to re-activate the PV system. The coating does not contain any adhesives and does not damage solar panels in any way. The coating can be peeled off up to 12 months after being applied even when exposed to UV and other weather elements.


Once it has served its purpose PVSTOP can be peeled off the solar panel by hand, condensed into a small ball and disposed of safely in domestic waste.


PVSTOP empowers fire & rescue services, site first responders, electrical technicians, maintenance personnel and PV system owners and operators with a reactive tool that will render solar panels electrically safe when required.

Because PVSTOP is designed to be used in the event of short circuits, emergency incidents such as fire, flood or storms, as well as during routine maintenance, the product has several additional safety features:
