The following work incidental to the installation of
residential solar equipment shall be considered to be within the scope of work
of a solar contractor. Unless otherwise indicated, the solar contractor shall
be permitted to perform such work without subcontracting to a trade other than
that of a solar contractor, provided all work is performed pursuant to
applicable local, state, and national building codes.
(1) Electrical work. The branch circuit
supplying the electric water heater, the receptacle outlet for a
cord-and-plug-connected solar controller, the swimming pool pump motor, or the
premises wiring on the load side of the premises service disconnecting means.
If installation, alteration, removal, replacement, or upgrading of this circuit
is necessary, the work shall be performed by licensed electrical contractors
only.
(2) Solar Water Heating
Systems. Solar contractors may disconnect and reconnect the existing branch
circuit wiring at the water heater. Solar contractors may install new or
replace existing control wiring attached to a cord-and-plug-connected solar
controller. For a photovoltaic pump controller, solar contractors may install
new or replace existing direct current power wiring between the photovoltaic
panel and the pump motor.
(3) Solar
Pool Heating Systems. Solar contractors may install new or replace existing
power wiring on the load side of an existing pump motor disconnect. Solar
contractors may also install new or replace existing control wiring connected
to a solar pool controller.
(4)
Solar photovoltaic systems. Solar contractors may install new or replace
existing power and control wiring in photovoltaic (PV) source circuits, PV
output circuits, battery storage system circuits, and power conditioning unit.
In an interactive system that operates parallel with a primary source of
electrical energy, this work is limited to the PV supply side of the power
conditioning unit. In a stand-alone, or non-grid connected system, the work
above-referenced shall be limited to the PV supply side of the power
conditioning unit and shall not include wiring integral to the building
premises.
(5) Plumbing. The solar
contractor shall perform all work required for the installation of a domestic
solar water heating system and solar pool heating system, including connecting
the solar hot water system to the existing cold water supply and hot water
lines at the existing domestic water heater location.
(6) Roofing. Solar contractors may perform
roofing work directly related to the installation of a domestic solar water
heating system, solar pool heating system, or photovoltaic system, including
cutting roof openings and penetrations, installing flashings, attaching
equipment mounting brackets and solar panels. Such work shall be limited to an
area within 18 inches of each roof penetration or attachment.
