“Two comparably sized households in
Californiaand
Massachusetts consume the average amount of electricity for an American household, about 11,000 kWh annually. The California household needs a 7.0 kWh system to cover 100% of their energy needs. By comparison, the comparable household in Massachusetts needs an 8.8 kWh systems to cover their energy needs.
Solar panel systems in California are smaller than the
solar panel systems in Massachusetts but are able to produce the same amount of power because they’re exposed to more sunlight each year.”
Won’t let me post a link but I’m sure if you copy and paste the above to google you will find the article I quoted.
That’s not pertaining to my region in specific but first bit of info I saw stating that solar can potentially cover 100% of residential house hold electrical consumption in areas with constant, intense , direct sunlight. So can you please either contribute to this discussion or just get the fuck out of this thread if you have only your shitty attitude to bring to the table?
Let's break this down to where it all becomes clear. This will be my last attempt to educate you folks.
The average American home uses right at 11,000 kw (10,866 to be exact) per year. That is not exclusive to California. That boils down to about 30 kw per day.
Now, a 7kw system will run you around 25,000 dollars less whatever incentives are running at the time.
That system, running full tilt will produce right at 25 kw per day on average. Of course it's lower in the morning, a bit higher at peak sun and then lower again in the evening. The important thing to remember is that it doesn't produce this
AT A CONSTANT RATE.
So that right there should get you asking, "how can a system that produces 25kw per day provide 30+kw per day of power?"
It can't.
You can't run this solar system to your air conditioning system and run it full tilt non stop. It simply doesn't produce the amount of amperage needed to push that level of power. If you did do it, the AC would kill the entire system
VERY quickly. Then you'd be back to square one of waiting until the next day for the sun to recharge the battery banks completely. (for the record, the typical AC unit will use about 3.5 to 4 kw
PER HOUR.)
What you do with solar is power everything else: all your lighting, your TV set (provided it's not an old dinosaur projector or some other power hungry device) your computer, etc. All of your basic household circuitry.
Even with that, under normal usage your battery banks will be expended in about 6 hours to the point it will switch off to recharge, so the last few and first few hours of ever day are spent charging exclusively without ability to use, then they charge as they discharge as well to extend usage at peak hours.
Contrary to what the article states, which I could not find by the way, you will
NOT get 100% of your power from that system. I think what it's trying to do is say you can get 100% of your non-appliance power (power for everything except major appliances such as AC, refrigerator, dish washer, water heater, etc.) from that system, which would hold water. You can expect to save about 1,500 to 1,800 dollars per
YEAR on your power bill.
That's a far fucking cry from the 340 per month claimed at the start of this thread by somebody that will remain unnamed.
That is, in fact, the same level system we looked at installing and decided against it solely because of the money up front needed to get it going. To us, it simply wasn't worth it with the few incentives we were offered at the time.
