Warranty
Dave Lennox
Signature
®
Collection air conditioners and
heat pumps have a 10-year limited warranty. The Lennox
®
Solar Sub-Panel accessory is also covered by a 10-year
limited warranty.
The PV AC module consists of several components, each of
which is covered by its own warranty. The frame on the panel
and the balance of the system components (roof mounting
hardware, etc.) are covered by a 10−year limited warranty.
The solar module is covered by a 10−year workmanship
warranty and also has a power output guarantee. The power
output guarantee states that the output of the module will not
degrade over time more than a set percentage of 0.7% per
year for 25 years. The micro-inverter has a 25 year limited
warranty. The Envoy Communication Gateway has a one (1)
year warranty. Warranty for these items are handled by their
respective manufactures
.

Glossary
Microinverter
— A microinverter is a device that converts
the direct current output of a single solar panel into
grid-compliant alternating current power.
Module
— The technical term for a solar panel.
NEC
— National Electrical Code
which contains safety
guidelines and required practices for all types of electrical
installations. Article 690 pertains to solar photovoltaic
systems.
Net Metering
— Allows the exchange of any surplus energy
produced by the PV system. This means that the electric
meter spins backward when power is flowing from the home
to the utility and spins forward when power is flowing from the
utility to the home. At the end of the month, only the net
consumption is billed to the homeowner.
Nominal Operating Cell Temperature (NOCT)
— The
reference module operating temperature presented on
manufacturer's literature. Generally the NOCT is referenced
at 25
C (77
F).
Open-circuit voltage (Voc)
— The maximum possible
voltage across a photovoltaic module; the voltage across the
module in sunlight when no current is flowing
.
Photovoltaic peak watt
— Maximum rated output of a
module, or system. Typical rating conditions are 0.645 watts
per square inch (1000 watts per square meter) of sunlight,
20
C (68
F ) ambient temperature and 6.2 x10
-3
mi/s (1 m/s)
wind speed.
Power Factor
— The ratio of the average power and the
apparent volt-amperes
.
PV
– Abbreviation for photovoltaic
.
Short-circuit current (Isc)
— The current flowing freely
from a photovoltaic module through an external circuit that
has no load or resistance; the maximum current possible
.
Voltage at Maximum Power (Vmp)
— The voltage at which
maximum power is available from a module.
Watt-hour (Wh)
— A quantity of electrical energy when one
watt is used for one hour.
