Links to good home solar tech info?
I'd begin with this tool https://tsi.tyconsystems.com/html/nrel_lookup.htm which was spot on in showing me how many peak solar hours I get in my zip code per day and how that changes per month. At least for me (Birmingham, AL area) the peak solar hours per day were calculated not just to account for hours between sunrise and sunset each month, but also based on sunny days/cloudy days/rainy days.
If you have your past 12 power bills either in paper or online, look at the past 12 statements and compare the # of kWh you pulled from the grid that month with the # of peak solar hours you get per day. What I did was get enough solar panel kilowatts (kW's) so that I'd meet most but not all of my needs (assuming I was able to store enough in battery storage for night). Here's how it works. Last July my house consumed 2,339 kWh (in my case I now get that data from the inverters since the power company now doesn't know most of the power I consume because I don't pull most of my power from the grid). Divide that by 31 days and I need 75kWh per day. The peak solar hours tool says I average 5.6 hours per day. 75kWh / 5.6 hours = 13.4kW <--- that's how much solar capacity I need to bring in (on average) to meet my home's needs (on average). Do that for all 12 months.
Then take a hard look at when you consume power in the day. If you're married and both of you work away from home, then chances are your house consumes little power during the day (unfortunately that's when solar is most plentiful) and then you make up for it in the evening and run all of your appliances to cook and do other chores. That means you'd have to have more battery storage than a retired couple at home half the day doing most of the power consumption in the middle of the day. So figure out how much battery storage you'd need each month to get through most nights.
And figure out how much your highest power demands are (i.e. if the AC is running and consuming 4kW while the wife is cooking and consuming 5kW while the dryer is on high consuming 6kW while the husband is in the hot tub consuming 3kW, that's a total of 20kW at that one point in time that your inverters would have to produce AC power from DC power to keep from having to pull from the grid). If that happens a lot then you have to get inverter capacity to meet those needs most of the time.
Last but not least do a deep dive into what it takes to make your home more energy efficient regardless of if you go solar. For details on how I incorporate it all as one energy project, see https://freerepublic.com/focus/news/4183380/posts?page=138#138.
If you want more I'll see if I can dig up old resources I found two and a half years ago when I got tired of Brandon's dumb energy policies and went solar.
