SOLAR VOCABULARY
Photovoltaic (PV) Technologies
More commonly known as Solar Systems. Photovoltaic cells absorb energy from the light of the sun which is composed of particles of energy called "photons". These cells are then connected to form a solar panel also known as a module.
Solar Battery
An electrical storage device used to store the electrical energy generated by a photovoltaic panel in a solar installation. They are also known as “photovoltaic batteries”.
Soiling
The process by which photovoltaic (PV) panels accumulate airborne particles. This process impacts the performance of the PV energy system. (This is the reason that recommended that you wash your panels periodically).
Permission to Operate (PTO)
The final step in the interconnection process where you have passed final inspection from your local jurisdiction and received approval from the utility to activate your solar system and begin generating electricity.
PV Modules
More commonly known as solar panels. The devices placed on your roof used to convert light from the sun into electricity that can be used to power your electrical loads (appliances) in your home.
Inverter
A device with the main function to change direct current (DC) from solar panels to alternating current (AC) to power your home. The inverter comes in two variations: one is the central inverter which mounts on your wall, usually next to your main service panel, and the second is the micro inverter which is contained underneath each solar panel on your roof.
The inverter itself does not produce any power, instead the power is provided by the DC source (the solar array).
Local Jurisdiction
The local government or legal body that has the authority to make and administer laws to individuals and companies who are conducting a construction project.
Solar Array
A collection of solar panels that are grouped together to generate electricity. When an installer talks about solar arrays, they are typically describing the group of panels that are grouped together on a single roof slope.
Unpermitted Structures
According to the California Building Standards Code, no building or structure may be manipulated in any sort unless a permit has first been obtained from your local jurisdiction. Having an unpermitted building structure can create serious problems for the homeowner as the local jurisdiction may have the homeowner request a permit, bring up to code, or have the structure removed. The local jurisdiction can also refuse to pass the solar unless these conditions are met.
Solar Orphan
Someone who bought a solar system from a contractor that is no longer in business. Oftentimes, that solar system has been installed improperly or has been installed without going through the proper permitting channels.
