This is a little expensive and is not an Advertisement but, it beats trying
to re-invent the wheel; Amazon.com has Grid tie inverters and Solar panels
Two wires to the Grid inverter from the Solar panel, plug in the Grid inver
ter to your outlet and your off to the races Saving money.
Of course you can add more Solar Panels for more power.
Of course you can add more Solar power wattage then you actually use.
Of course this will reduce your Power Bill.
Of course on the Positive side will pay you IF you use less than you Genera
Of course you will be able to see your Power meter slow down.
Of course you will be able to see your Power meter go backwards.
Lets say your Power bill is $50 a month at $.09 for 1000 Watts an hour
So, your usage for 31 days X 24 Hours66.666666666667 Kilo Watts
=2.240143369175627 Kilo Watts an hour (Hmmmm, 2KW an Hour seems high)
IF I did my math right; You need 43+ 100 watt Solar panels and five 1000 wa
tt Grid inverters to make your Power meter go backwards (Considering night
43 X $50 = 6450 <---Just a Guess ya gotta shop a little
5 x $00 = 150 <---Just a Guess
$600 Plus Wires, Bolts and Stuff <---Just a Guess
No power Bill and Pays ya back in about 4 Years <---Just a Guess
After that the money from your power company goes in your pocket!
Side note; Of course you can charge your Car Battery☺
Thanx for Reading and Enjoy!

No utility will pay you for excess energy or install a buy back meter
unless the system is installed by a certified licensed contractor. Plug
& Play grid tie inverters don't qualify. They intentional do this to get
you to spend a fortune and then the contractor receives the federal tax
You are on the right path though. Add a little, then with the savings
you see on your electric bill, buy more panels a little at a time. You
will never get rid of the electric bill altogether. They will still
charge you a base charge. The key is to offset your usage. Solar panels
do nothing for you during the night, so you might want to add a wind
turbine, or even a biomass gasifier to fill in the gaps.
I also believe they limit you to 5KW of power generated before you have
to pull a permit and get annual inspections from a city inspector. The
minute you go over 5KW, they want a licensed contractor involved.

Just curious as to where it is that "annual inspections from a city inspector" are required.
I'm in eastern Maine and just brought in grid-power to our (formerly) off-grid home. The system needed to have been installed and/or inspected by a licensed electrician, but once certified, there's nothing else required.
Oh, and the limit in Maine is 10kW (nameplate generating capabilities of the system) for what they call a Level 1 connection. Higher power generation capabilities do call for more detailed inspections and testing, but by the power company, not a local inspector.
In Maine, we have net-billing, where the meter runs backwards if I generate more than I use; unfortunately, if I generate more than I use, the credit gets zero'd out every twelve months. Minimum charge is $.63 / month (and that would include 100kW -- not sure if I get credit for that every month, or only in the months I am a consumer, probably the latter).

Got a link to those $.50/watt shipped and installed panels?

Not so fast! Your power company and your county building department
have "rules" about these things. You might be able to get by with an ad
hock sub-1KW installation, but it likely will never pay for itself. If
you have a smart meter, you might not even get away with that!
Also don't fool yourself that you are buying a standby power system,
because a grid-tie inverter requires the grid to operate. So if the
grid goes down, your system will refuse to generate power.
