At Air Stars, we install AC and heating equipment from many top brands. This includes HVAC units that can be powered by Lennox solar panels. Lennox is known for its high-quality heating and cooling systems and highly efficient solar module system.
The manufacturer’s latest offering is the Lennox SunSource® Home Energy System. It consists of roof-mounted modules that turn energy from the sun into electricity to power your home heating and cooling equipment. When your HVAC is not running, the electricity generated can be used to power other devices. The excess can also be sent to the utility company for potential utility credits/rebates or federal or state tax credits.
The system also:
- Lowers the cost of a solar installation.
- Is expandable to up to 17 modules.
- Includes a communications module to review power production, environmental benefits, etc.
Here, we’ll explain how Lennox solar panels are connected to the system so you can benefit from this advanced technology.
Connecting a Lennox Solar Subpanel Accessory
The solar solution works with the Dave Lennox Signature® Collection Solar Ready HVAC unit and only units labeled Solar Ready. The sub-panel handles 15 amps and each module has a DC rating of 265 watts. A micro-inverter converts DC to AC power; with an efficiency of about 96%, it yields an AC output of about 250 watts from each panel. Each module is 46.7 pounds and has dimensions of 65.94” x 39.41” x 1.22”.
Mounting Lennox solar panels
Roof mounting kits are available from Lennox. To mount the solar modules, follow these tips:
- Mount the Racking System: The modules mount onto rail-based racking. Individual rails mount onto roof flashings (flat tile, composition shingle, or barrel tile flashings depending on your roof). Each mounting kit includes the flashings, rails, and hardware for roof penetrations.
- Face the Solar Modules to the South: The modules should face south, while the ideal angle of tilt is determined by the latitude of your home’s location. Some mounting systems adapt to the pitch of the roof, while flat-roof mounting systems are available by special order.
- Determine the Best Distance from the Unit: The maximum distance between the modules/HVAC unit is determined by the power line carrier system’s ability to transport energy. Wire size matters too. If you have 17 modules, a #10 wire can provide energy at 60 feet with a voltage drop of less than 1%, while a #6 wire can do so at 154 feet.
- Install a Microinverter: Trees provide much-useful shade that can improve comfort and efficiency inside your home. However, shading can reduce the output of a solar module. With a microinverter, significant shading on one module won’t have much effect on the rest of the modules in a string.
Mounting the Communication Module
The Lennox system includes a communications gateway that plugs into an electrical outlet. Data is communicated via power wires and a power line carrier. An Ethernet cable connects the gateway to a broadband router. Once data uploads to a server, you can view system information online.
If you don’t have internet access, a computer with an Ethernet port can be used. Another option, if you choose not to install a communication gateway, is to inspect the microinverters directly. If their indicator lights are on, they’re functioning. You can also measure amperage and voltage directly at the connection to the outdoor HVAC unit. Therefore, a communications gateway is not necessarily required to install a solar system.
Do I Need a Professional to Install Solar Panels?
It’s not recommended, or completely legal, to install Lennox solar panels yourself. A licensed electrician will at least have to supervise the installation. Local requirements can vary considerably, so it’s important to consult with a local electric utility and technician. Full knowledge of National Electrical Code (NEC) requirements is needed for solar module installation. While courses are available, a qualified installer has the knowledge, expertise, and tools to complete the installation quickly and safely.
You may also need a special utility meter, depending on the company. They can inform you of suitable equipment. For example, specialized equipment may be needed if your utility has a net metering program that allows you to move excess power back to the grid. There are also different certification programs for solar installers, including from the North American Board of Certified Energy Practitioners (NABCEP).
Contact a Professional Installer
A qualified installer can help by:
- Determining the right size of system for your home.
- Calculating how much you can save.
- Working within the terms of the module and equipment warranty.
- Communicating with your local utility to determine exact requirements.
- Following all technical and safety protocols to ensure a smooth installation.
