Many Dave Lennox Signature
®
Collection air conditioners
and heat pumps manufactured after April of 2010 are
factory-equipped with components that make them
SunSource
®
solar-ready. These units can be matched with
solar modules and other optional equipment so that they can
become part of a SunSource
®
Home Energy System.
Units can be upgraded for use with solar equipment at the
time of installation or in the future.
Solar energy is first used to meet cooling/heating demands.
When the outdoor unit is not operating, the system powers
lighting, appliances and other electronic devices in the
home. Any surplus power is sent back to the utility company
for a possible credit (check with your local utility company for
availability).
See bulletin number 210680 for a complete list of all
available SunSource

Pre-engineered Kits for ordering.
Wiring runs from the roof-mounted solar modules to the
outdoor unit. From there, power travels to the home
electrical service panel using the existing outdoor unit power
wiring.
