Move to a small town in TN. No code dept

... or Carolina. i have tons of solar and never a need for a permit.

I also have SoCal Edison and self installed my own solar about 5 years ago and have since added storage. My panels are already paid for. Storage has about 7 left. Our energy costs a lot.

Can you give more info. Did you do permits or undercover? Did you hook whole house up to off grid portion or just part of the house?

I live way above Florida and the NREL estimates a yearly energy production of 5600 kWh for 4 kW installed capacity, i.e. a very short ROI of less than 2 years at the national average cost of electricity (0.17 USD per kWh). Of course this would significantly increase with the cost of inverters, even more with battery and then paying for install would "kill the deal" but the ROI on solar panels themselves is very short nowadays.

I also struggle to understand people's ROI calculations not considering utility rate increases…here in Atlanta my rates have been crazy and we are now on the EV/overnight advantage plan to the point i basically crank my AC down at strategic points in the day regardless of being home to hedge needing to crank on the AC during peak hours. While this is saving me money, there is no guarantee Georgia power will continue offering this plan or continue to increase rates and/or rate time ranges (eg decrease the off peak hours, etc.). Long story short - anyone calculating an ROI should be coming up with at least 3 values; none of which would show an energy price decrease. My biggest curve ball and reason for holding off is waiting to see when the next wave of large capacity battery storage will be consumer ready (eg solid state, etc.), which at this point is probably what I will end up waiting for with god knows what in this legislation that is about to pass.

Well that's not right. I have 24 350watt panels. I haven't paid a power bill in years (my agreement is averaged throughout the year). That includes my EV car.

Will this charge my Tesla

Yes, but you will need a charge controller/inverter, micro inverters, cabling ,shutoffs, and a few more things. You can find a lot of info on YouTube.

31 cents per watt - pretty cheap. Typically you find such wattage panels in the 30-50 cents per watt range. You can get cheaper lower watt panels for 25 cents per watt or so.

agreed, only real question then is build quality and longevity although in 5 years there will probably be one that has the same foot print with 2x the output.

I'm trying to understand how people are computing ROI. At current utility rates of roughly 21c/kWh, I'm already paying less per month for electricity with professionally installed panels than I would otherwise. My ROI is ... right now? That's without any utility increases in the next 10 years (life of the loan).

Will we have any issue to get Tax Credit, etc. by doing DYI with this?
I guess there are some credit from SoCal Edison as well?

I got 15 iq7+ micro inverters, 15 LG 365W panels, total cost with installation and permitting (after tax credits) was $10,200In April 2021ROI is looking like 8 years

I have 23 395watt panels with iq8plus micro-inverters, problem with those is they will not work unless connected to the grid, so NO power from them if the grid power fails. Enphase says I have to pay over $10K more for an Enphase interface and get it installed by an Enphase trained tech. Then I can add batteries. Still, the system is good for keeping my Southern California power bill under control. I am investigating the use of a EG4 12KPV as it is supposed to be able to fool the Enphase system into thinking it is connected to the grid, once the grid fails.

Is this a good deal on a kit? It uses 12 x 410W panels. Or would It be better to buy the inverter, battery and BMS separately?

Not sure where people are with the ROIs on these I did the math and if everything worked out perfect it was something like 15-20 years. That also assumed that the components didn't need to be replaced, my time for maintenance etc.

If you are static mounting them (vs on a system that tracks the sun) realistic you might get 30% of rated capacity ( and lose to conversion if going to AC ) per hour of daylight unless you are washing them off frequently they will get dusty/dirty, clouds, rain, ice/snow ( if more north ), bird poop, etc etc.

Living more northern than Florida/etc reduces efficiency as well, and the components probably are not ALL going to last for 5yrs+ so you'll be fixing it and investing money and testing and maintaining ( and potentially a fire hazard )

Then you also have to look at the investment potential in some cases people are spending 20k plus that's not an insubstantial amount of money, invested in the s&p500 in the last decade it would have earned a good amount likely outpacing the savings of solar.

I guess it's also nice we live in a relatively low cost of power, I think we are paying like 0.09 per KWH so it makes it really difficult to show a 3-5 year ROI which is what I generally look for... Maybe if I was paying closer to 40c per KWH I could see it but you just have to math it out and the variables for your specific scenario.

There is no washing or maintenance

Separate them. batteries are about 800 each. inverter about 1500 or less, solar panel around 120 or so each.

Any brands you can recommend for each item?

10 kilowatts of solar of would give 1/4 charge in a day? Maybe for a Hummer EV!
