No, the proposed earlier sunsetting of subsidies won't completely kill new solar installations...
Agreed, I did claim the tax rebates for installing my rooftop solar, garage battery system and high UV reflective windows but the tax rebates were never a consideration when deciding to install any of them. I had the available savings to pay cash, wanted to stop paying up to an unknown few hundred dollars per-month for grid power, i.e. I simply re-position existing savings into my property, raising it's resale value and it permits me to deposit more to savings per-month thereafter from reduced power bills. My background usage is 0.5kWh (1706.07 BTU) and peaks at about 2kWh (6824.28 BTU) for minutes long periods based on home appliance usage. I admit I now use all the data from the IOT parts and schedule appliance usage to minimize grid consumption. I have a dual-flow electricity meter and submit a varying amount into the grid up-to about 4kWh (13648.6 BTU) that obviously varies all daylight hours. I run off the battery for most of the night and get about 97% self-sufficiency from April to October with regular electricity bills of around $10 per-month (cost of having the meter) even running my air-conditioner in the hottest days. The new windows should reduce that usage and seem to help reduce winter gas bills as well, the final few should be installed in the next month, they were also paid cash from savings with an assumed improvement in my home value (though probably not the whole cost of the windows) but reduced monthly costs meaning more avaailable for me to save per-month thereafter. The peak winter electricity bills are about $40 because the heating source is LNG and electricity just runs the fan on short, lower light days (winter heating runs mostly at night anyway). The power company chooses to pay a lot less for received energy from my solar system than it charges for delivered energy I use from the grid. I'll probably double the size of my battery system and maybe add a few more solar panels some time after the last of the high UV reflecttive windows. I'll do it regardless of tax rebates, aiming to hit 100% self-sufficiency for electricity usage at least.
