Westinghouse Solar AC Panel Design and Performance
Ordinary solar power systems use a centralized inverter, and require the installation of a separate
racking system to mount the panels. These ordinary systems also require manual interconnection
of high voltage DC wiring, and manual grounding of all panel and racking components. With the
racking, wiring, grounding and inverters built into Westinghouse Solar panels, installation is much
easier, reliability is greater and performance is 5 to 25% higher than ordinary systems.
The rating on each panel indicates the nominal DC power output in watts of a panel when it is in
bright sunlight in 25 degree C conditions, and the sun’s rays are perpendicular to the surface of
the panel. Because the inverter operates at about 95% efficiency, the AC output of the system will
be approximately 5% less than the peak DC output. So at peak conditions, a 235 watt
Westinghouse Solar AC panel will produce up to about 223 watts of power. In real world
conditions throughout the day, as the sun rises, moves across the sky, and then sets, the output of
the panels will increase from essentially zero at dawn to a peak of about 175-214 watts
(depending on season, sun angle, mounting angle and roof orientation), and then decline again to
zero. Each panel operates independently, so if one is shaded or dirty the adjacent panels will still
operate to maximize their energy output.
Westinghouse Solar AC panels use Enphase micro-inverters, which are mounted on the back of
each panel. The easiest way to determine the output from your Westinghouse Solar AC panels is
with the optional Energy Management Unit (EMU). The EMU communicates with Enphase’s
“Englighten” website for real time reporting and analysis on the performance of each of your
Westinghouse Solar panels. The EMU is installed by plugging it into any convenient 120 VAC wall
socket and providing an Ethernet connection to your broadband router or modem. After
installation of the EMU, the full network of Westinghouse Solar AC Panels automatically begins
reporting to Enlighten. Alternatively, you may measure the voltage, current and power output of
each branch circuit of Westinghouse Solar AC panels with conventional electrical instruments,
taking the appropriate cautions when handling live electrical circuitry.
4. Using this Guide
This guide will familiarize you with the fundamentals of design and installation of your
Westinghouse Solar Power System. The guide also serves to illustrate the simplicity and
efficiency of solar design when equipment is developed in unison with each other. Westinghouse
Solar Power Systems consist of hundreds of individual separate parts built into one integrated
solar electric system delivering easier, faster design and installation over ordinary solar
installations.
This guide contains three primary sections. The first section covers the physical properties of solar
design specific to the Westinghouse Solar Power System, including how to layout your
Westinghouse Solar Power System, how to choose components, and the structural requirements
