Homes get it. This is a residential installation. Rules for businesses are different, and frequently change, at least around here. Unfortunately our warehouse is in a nearby town that has its own municipal power and they offer no energy saving incentives of any kind. No net metering, no credits on energy saving appliances, nothing.
Yes. Every state is going to be a bit different, and in our state (Delaware), you get contracts for about 20 years. For us, the rate sort of depends on what year your system is installed. But not every state has this - previously we lived in Virginia, and they have nothing.
Yes, the main point is the electrical rates vs total cost of the solar roof project. If the rates are low enough not a lot of people get excited about spending 15K to 20K dollars going solar.
I guess you can move to California where if building a new home you would be forced into it: https://www.azcentral.com/story/mon...-california-requirements-new-homes/602206002/
At a vacation house in SC we've rented a couple times there was an automatic solar heating system for the pool. It had a motorized valve, a temperature sensor in the array on the roof, a sensor in the pool side of the water loop, and a dial to change the setpoint. It would prevent the pump sending the the pool water up to the roof "heater" and radiating all the heat out of the pool overnight.
Or wait for the regressive state legislature to turn over- could happen sooner than we expect. Residential solar installations are growing rapidly in Arizona despite the current legislature being hostile to the industry. That's interesting about the California building requirement. I'm surprised that I hadn't heard about that.
How is it "regressive or hostile?" I don't know so please explain.
Interesting.
Yeah, the system only really saves AC cooling costs if you leave the pool uncovered. Basically, by providing a cold-side heat sink to accept rejected heat, your pool becomes a large radiator. Pools of larger surface area (gallons is immaterial) are more efficient in lowering the AC electric costs; it's especially effective during hot/dry times (April-ish until monsoon season, then after monsoon until it cools down in October-ish). So, it's a 'shoulder season' aid. It will still decrease cooling costs during warm/wet monsoon season, but not as much. Our house uses about half the annual cooling energy to cool during shoulder season, and the other half usage is during monsoon season (more enthalpy in wet, warm air to remove).
Sounds similar to a heat pump. Works well in middle temps (30-80F) but not that great on either extreme.
This is one of the biggest reasons I didn't go with solar a while back when I last got estimates. The TDSU (Transmission and Distribution Utility) gets the lions portion of the bill and solar only reduces your consumption. So no matter what I do I still end up with over $100 bill a month for the TDSU and other things alone. When the transmission charges are more than the use charges, don't think it will sell much. Even if I generated all my own power and then some I would still end up with a nearly equal bill anyway between paying for the solar panels and the distribution charges.
My utility's distribution and other charges are based on kWh purchased. So if you generate 100% of your power in a given month, the ancillary charges are zero. Maybe your utility does it differently. I haven't had to pay a bill since March, where I used slightly more than I generated and had credits accumulated. Dec-Feb are lousy generation months here, not surprisngly.
Texas is 32/50 for tax burden. Massachusetts 22/50.
Can't tell if that's satire... but here's some numbers... who doesn't love numbers?
Wow, its that much more for CO2 caused GW. Thanks. No its not satire, but can help understand the whole picture....
