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.
The basics
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.
Types of solar systems
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.
Advantages of the SunSource® Home Energy System
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 15 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 sends 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.
