NFPA 1 provides guidance on how solar photovoltaic panels must be installed on the roofs of homes.
Generally, local governments require a homeowner's solar installer/contractor to obtain a permit for rooftop panels before they can be installed. After the PV system is installed, a professional from the local government will inspect the new array to ensure all building, electrical, and safety codes have been followed.
ensure that solar PV systems can be accommodated while achieving the goals of the codes. Some primary code issues that impact rooftop PV installations include: • Restrictive or ambiguous language written into the codes; • Lag time between the release of updated model codes and new PV industry best practices.
The first step in planning your solar panel installation is to evaluate your roof’s condition and suitability. In the Northern Hemisphere, a south-facing roof pitched between 30 and 45 degrees is considered ideal for solar panels. Your roof should be in good condition and able to support the additional weight.

6 FAQs about [What are the policies for installing photovoltaic panels on roofs ]
Can photovoltaic panels be installed on a building roof?
The installation of photovoltaic panels on a building roof or integral with a building roof also raises other code issues (e.g., roof loading, wind loading, fire ratings, weather tightness, mounting systems, roof penetrations, etc.), which may also be relevant for systems mounted on or integral to a wall.
Do I need a permit to install solar panels on my roof?
Yes, a permit is required before mounting PV panels on your roof. You have to meet safety and solar panel roof requirements before undertaking such a project. The exact permit requirements vary from one locality to the other. The size and type of solar unit will also influence permit requirements.
Do solar panels fit on a roof?
As your solar panels will sit on top of your home, the suitability of your roof is the first thing to assess. Solar panels can add considerable weight to your roof, especially when installing multiple panels at once. It's vital to consider factors like: Your roof needs to be stable, strong, and secure.
Should I install a new roof before installing solar panels?
It is ideal to install a new roof before putting solar panels on your roof as your roof must be in good condition to support PV panels. The average weight of most residential solar panels is around 40 pounds. These panels plus mounting hardware add about 3 to 4 pounds per square foot of load to your roof.
Do you need a roof expert for a solar PV system?
It is recommended to consult a roof expert to assess your roof condition before installing a solar PV system. Modern modules require approximately 6 hours in sunlight to recharge. Any shade around your roof, such as from nearby buildings, trees, dormers, chimneys, or other obstructions, can significantly hamper the production of your PV system.
What should be the incline of a solar panel roof?
When purchasing PV modules, ensure you determine the size of your roof. One of the solar panel roof requirements is the roof pitch, which is obtained by dividing the rise by the roof span. The ideal roof incline for solar installation is 30 degrees (in construction terms, this is a 7-pitch roof).
