You can go to their website and they will give you a brief description of the system. Sounds pricey both for acquisition and upkeep.

This website is terrible - no explanation, just a list of products.

LOL, any device that uses electrical power is solar system ready. All that's needed is determine loads of what you plan to use the solar system to power.

The idea behind Lennox thinking is more or less --- making the HVAC system more energy efficient by tying a solar system to grid power and using the solar power provided by the panels during the heat of the day, which is typically when your AC is needed. Typically these solar systems are sized to handle the AC load and not the whole home.

So because you need cooling when the sun is out, the system primarily uses the solar energy provided by the solar panels. When the sun goes down, the system uses normal grid based power.

The con is in the cost of another system that will need maintenance and repairs. If you price you pay for power is below 14 cents per KWH you will likely lose cost wise in installation and repairs of the solar system. If you pay 20 cents or more per KWH you stand a much better chance of the solar system reducing your energy costs which can reimburse you for any repairs needed as the solar system ages.
