  • Why Solar?


    Homeowners across the globe are seeing the solar light. The reasons vary for each person, though they mainly come down to the following


    Solar-energy systems allow you to capture free sunlight and convert it into usable power in your home.


    Solar energy can be used to heat and cool your home, but it has almost no impact on the global climate. By comparison, electricity generated by power plants produces carbon dioxide emissions that scientists say pose serious threats to the environment.


    While nonrenewable energy sources like oil, gas and coal are becoming increasingly scarce, the sun’s energy is limitless. Wherever sunlight shines, electricity can be generated.


    Having a system that creates solar energy means you use less electricity from your utility company, and that can contribute to lower heating and cooling costs. This is significant, especially when you consider 48% of energy use in a typical U.S. home comes from heating and cooling*. To find out how much you can save by harnessing energy from the sun, use our solar calculator.


    The U.S. federal government and some states provide tax credits for renewable-energy systems. Depending on where you live, you may also be eligible for incentives through your utility company. To find out what incentives are available in your area, visit


    The more sunlight harnessed by the system, the less electricity you need from your utility supplier.


    An investment in a solar-energy system may improve the value of your home. Surveys conducted by the U.S. Department of Housing and Urban Development have shown that, for every $1000 saved per year, $20,000 may be added to a home’s value.


    The sun has been around for billions of years and is likely to burn on for billions more to come. And when you consider how a trusted name like Lennox is putting it to economical use in the home, it’s easy to see solar energy’s future is bright.

  • How Solar Works


    Solar-energy is an infinitely renewable resource that uses the sun’s rays to generate electricity for use in your home. By going solar, you can reduce your energy costs and also lower your dependence on fossil fuels, thereby making your own contribution to a cleaner environment.


    A residential solar-energy system uses solar modules, made up of photovoltaic (PV) cells, to harvest the sun’s energy and convert it into electricity that can be used to power your lights, appliances and other electrical devices in the home.


    Grid-tied PV systems
    A grid-tied system is the most common and least expensive of all residential solar systems. It allows you to use your own solar-generated electricity to save energy and reduce costs. At times when the PV system isn’t producing electricity, such as at night, electricity is provided by the utility company’s grid, or network of power stations.

    One of the benefits of a grid-tied system is that any excess electricity produced by your solar system can be fed back to the grid through a process known as net-metering. With net-metering, which is available in most areas, when you use electricity from the grid your meter spins forward. The less electricity you use from off the grid, the slower your meter spins. Even better, when you are feeding electricity back to the grid, your meter spins backwards!

    It’s important to note that the government and utility company rebate incentives that can make installing a solar system so much more affordable usually aren’t available unless your system is grid-tied.

    Stand-alone PV systems
    Stand-alone PV systems, also called off-the-grid or off-grid, operate independently from the utility grid, providing all of the electricity needed in the home. Stand-alone systems are much more expensive than grid-tied systems. However, for homes located in remote areas without utility service, or where installing power lines would be extremely costly, a stand-alone system is a good option.


    The SunSource Home Energy System is a grid-tied PV system that uses as its platform a high-efficiency air conditioner or heat pump from the Dave Lennox Signature® Collection. These units come solar-ready, which means you can add solar modules to create a solar energy system, if and when you want one.

    Upgrading to a high-efficiency air conditioner or heat pump from Lennox will allow you to reduce the energy demand of your home before adding solar.

    You can start small, with one or two modules, and add more (up to 16 total, per outdoor unit) when your needs change or budget permits.

    How SunSource works to reduce your utility costs

    • The solar modules harness the sun’s energy to power the SunSource® Solar-Ready heat pump or air conditioner.
    • When the heat pump or air conditioner isn’t running, the solar power can also operate other electrical devices in your home.
    • With net-metering, any surplus power goes back to the grid possibly entitling homeowners like you to a credit.
    • A communication module, which send performance information for each solar module to a monitoring website, allows you to see the system status, energy production, and also shows the environmental benefits of using renewable energy for your home.
  • Steps to Solar


    Are you ready to get started on the path to real energy savings? The following steps will help you prepare for installation of a SunSource® Home Energy System.


    Your Dealer has a detailed planning checklist to help determine whether your home meets all the requirements for installation of a SunSource Home Energy System.


    A southern exposure is best, and your roof should be relatively free of shade from trees or structures such as chimneys. Your Lennox Dealer will perform tests to estimate the site’s monthly and annual solar energy generation potential.


    Each solar module requires about 15 square feet of rooftop surface area. The number of modules you want installed determines how much space you need. Your Lennox Dealer will help you with the calculations.


    If you belong to a Homeowners’ Association (HOA), you might be required to submit your solar installation plans for approval ahead of time.


    An always-on Internet connection with broadband router is required to take advantage of the SunSource system’s web-based performance monitoring service.


    Your Lennox Dealer will check the grid power supplied by your local utility company and also inspect your home’s distribution panel to make sure all required specifications are in order. Your dealer will also need to identify all local electrical code requirements to ensure compliance.


    Ask whether your utility company has a net-metering program that will allow you to receive credit for at least a portion of the electricity your SunSource system generates. You will also want to learn whether you must meet power-generating thresholds to qualify for valuable rebate and incentive programs.

Lennox Solar Modules

  • Are the Solar Modules Easily Damaged?

    The modules are made of tempered glass and are laminated to a resilient substrate. They are rugged, durable, and weather-and-impact-resistant.

  • Will The Modules Look Awkward Or Obtrusive On My Home?

    The hardware that mounts the modules to your roof allows them to integrate nearly flush with the surface for a discreet appearance that does not detract from the overall appeal of your house.

  • How Many Modules Do I Need to Produce Enough Electricity to Run My House?

    The number of modules you need depends on several factors, including the size of your home, angle of your roof and so on. We have a tool that can help you determine the amount that’s best suited to your requirements.

  • Will I Need a New Roof Before the Modules Are Installed?

    The ideal situation for installing solar is to have a roof that’s in good condition. That way, you won’t have to bear the cost of re-installing the solar modules if your roof needs to be replaced or repaired within a few years.

  • Do The Modules Need to Face South?

    Yes, South-facing modules are best to maximize sun exposure. The closer to south the system faces, the greater the electrical output from the solar modules.

  • What Happens If The Solar Modules Are Shaded?

    Ideally, the solar modules should be installed in areas where they are free from obstructions that can cause shading, like trees and buildings. But, the unique design of the modules could provide energy savings, despite varying climate and lighting conditions. Unlike typical solar-panel systems, which have one inverter for the complete array, each SunSource module has its own microinverter that converts solar energy into usable electrical power. So any issue that might affect one module, such as cloud cover, doesn’t impact the other modules.

  • What Happens If The Solar Modules Are Covered By Snow?

    If it snows, our solar modules are installed at the angle of the roof, which may allow the snow to slide down and melt within a short period of time under normal circumstances. In the event of an extreme accumulation, you may need to brush off the snow to get solar power.

  • Do I Need to Clean the Solar Modules?

    In most regions, rain cleans them off automatically. However, if you live in a dusty industrial area, you may see a performance improvement from periodically spraying the modules with water. Please note that detergents and high-pressure hoses should never be used for cleaning.

  • Do The Solar Modules Need to be Mounted On My Roof?

    Modules are typically mounted on the roof, but can also have a pole foundation. Ground installations are best if your house is heavily shaded, or if buildings or other obstructions limit available space on your home’s roof.
