solar pre-cautions to keep you
safe when working with solar power.
Solar safety is just as important as every other subject covered on
this site, actually much more important. When working with solar photovoltaic energy systems, you
will be working with equipment that can produce several hundred watts of power, so it is important
the you are familiar with the general photovoltaic safety rules to
minimize your risk of injury due to accidental electric shock or other physical harm.
Solar Power Safety
Rules To Minimize Your Risk
The first safety rule to keep in mind when working with photovoltaic panels or
other PV components is, always stop working in bad weather. PV panels
can be blown around by the wind or a storm which can result in you falling or damage to
the PV system.
Do not apply pressure on PV photovoltaic panels by sitting or stepping on them or they
might break and cause bodily injury, electrical shock or damage to the solar panels.
Also never drop anything on the PV panels.
Through the entire process of photovoltaic solar installation, make sure you don't get
the home's sheathing wet or your roof may leak there after. This is
usually an issue with roofs that are just being built, but it can happen to older roofs
too, if you have missing shingles or if you remove them at any point.
Do not install a pv system in any location within 0.3 miles of an ocean or salty water.
Vapours and mist could interfere with photovoltaic equipment and cause damage or
Also do not install photovoltaic equipment in locations that are corrosive -
classified C5 by ISO.
Make sure that the roof where you'll be mounting your solar panels is strong enough to
support the weight.
This next pv safety
save your life. Make sure your entire PV system is properly and safely
to prevent electrical shock and injury.
Always follow all the specific applicable electric codes for your
area. Contact your local power company or electrical authority for details.
Never work when it's raining, immediately after rain or in wet or slippery conditions
or with wet tools.
- Never install a PV system near flammable gases or you could cause a fire or explosion.
- Cover your photovoltaic solar panels with an opaque
material during wiring to stop or prevent electricity production.
- Make sure the area underneath your solar panels is clean, clear and free of foreign
- Another solar safety rule is do not wear metallic jewelry when working on
your PV system, or it could cause electric shock.
- Also never touch any electrical contacts or wiring without proper protection and safety
- Do not use artificial or magnified light on the photovoltaic solar panels.
- Always install PV systems in accordance with your specific area's applicable electric /
photovoltaic codes and solar energy safety rules. Make sure
you consult local codes and other applicable laws and statues concerning required permits
and regulations for photovoltaic system installation and inspection
- As a basic rule, do not work on solar PV systems alone, always have a least one
other person with you in case of accident or emergency.
- When working on roof tops, always insure that extreme safety precautions (including
harnesses, lifelines and safety nets) are taken to prevent slipping, falling and causing injury
- Inspect all your power tools to ensure that
they are working safely prior to starting the installation of your pv
system. Also, use insulated tools when working on a photovoltaic system.
- Another solar safety rule you should always follow is never work in conditions of
snow or high wind or when these conditions are expected due to increased chance of
slipping or losing your balance.
- Inspect all your ladders and scaffolding and insure that they are safe and in proper
- Always get a second person to securely hold ladders as you climb and use
rubber latter mats to prevent the ladder from slipping.
- Wear all necessary protective safety clothing including work clothes that
fit well and allow you to move easily and freely, non-slip shoes, insulating gloves and a
- When installing a pv system, use scaffolds (not ladders) at heights 6 foot and higher.
- Be very careful of falling objects and do not ever throw objects up or down when installing
a pv system.
- If there are utility company electrical wires attached to or near the roof, contact
the utility company to insure protective measures be put in place to prevent
- Always protect your wires or cables
with flexible metal conduit when wiring through walls, for wires exposed
to sunlight, rain or anywhere outdoors. Failure to follow this photovoltaic solar
safety rule can result in electrical shock or short circuit.

conduit by clicking here to go to the Installing Conduit section of our website.
- Use waterproof fittings or duct seal to prevent water from entering the conduit and
damaging your photovoltaic system.
- Always connect a grounding wire from the mounting hardware to the earth to prevent

Follow the Photovoltaic Safety Rules
Specific To Your Area
Always follow the rules for solar installation and
solar safety set forth by your municipality when installing a pv system. If in doubt,
consult your municipality or a certified professional. All electrical wiring should
be performed according to the provisions of the National Electrical Code or similar applicable
document in your specific area. Grounding work and wiring connections to the inverter should
be performed by a qualified electrician.
