    I have a customer that had 3kw of solar panels on his house. 3 ton heat pump. It's central Texas weather. Keeps his house 78 during summertime. He said it lowered his electric bill $50 a month if that puts your savings in perspective.
    I like DIY'ers. They pay better to fix.

    They can work stand alone. The A/C system is set up to make it easier to install the PV system, thats all.

    How many times must one fix something before it is fixed?

    In our region, it probably wouldn't make sense. To qualify for the MicroFIT (under 10Kw Feed In Tariff) program, your panels and inverters need to have a certain percentage of domestic content. Bypassing the MicroFIT program would be uneconomical - OPA pays you 80.2 cents per kWh for energy sent to the grid, while you buy it back for around 10 cents.

    Because of this, solar installations in Ontario always send 100% of their power through the export meter, rather than using it for internal building loads directly.

    Even if it weren't for the MicroFIT dynamics here in Ontario, if I was going to spend the money on a solar PV system, I'd probably want it to be stand alone rather than tied to a major appliance such as my HVAC system unless there was some serious cost savings in doing so.

    The Lennox system doesn't need to be ran through the HVAC system.

    For cooling after the sun goes down.......would you not need a large bank of 6V HD batteries to release their electricity via an inverter to change voltage back into 120V AC?

    This isn't an "off grid" solution, so you still have your connection to utility power to take care of that.

    Well, yeah I knew that. But why pay the power company when you have cheap power already stored up in your battery bank.

    Google micro inverters for solar. Each panel has its own micro inverter. This is how the Lennox system operates, it has to be connected to utility power. It is not designed to be used with batteries. You would need a DC solar setup for that.

    Because you would need a lot more panels and a large battery bank to store enough power to run the A/C after the sun went down. Which would cost a whole lot more.

    Its simply a way for a customer to be a bit greener.

    That takes a different kind of setup and inverter. Your up front cost is much higher.
    Remember, Air Conditioning begins with AIR.
