If I were building my own home or lived on a farm, I would, at least, look at seeing if it was feasible to set up a system of solar power and wind power to charge an e-generator so when it becomes charged, I could disconnect from the electrical grid for a a day and run my house on the power from the generator.
That’s where I see solar and wind being useful. I would not have a system where I was dependent upon them in any way.
I’ve implemented solar for my home. My trial run of using a small system for a year showed that it was more than worth the cost for my climate and power consumption habits. So I converted my two natural gas appliances to electric and made my cooling more efficient (variable speed heat pump, electric furnace, hybrid water heater) and added onto the solar. Since it was time to replace my wife’s car anyway we now have an EV car. And I added onto my solar system.
The result is 81% of my power consumed in the past 365 days came from homemade solar power, pulling the other 19% from the grid (mostly in the 4 coldest months). That includes charging the EV enough to drive it 15K miles (not counting charging it away from home on road trips). I’m an example that even with lots of solar, we still need a dependable grid. It’d be infeasible to invest enough into the solar to be 100% off grid without reducing our lifestyle (law of diminishing returns).
But I warn you it takes LOTS of homework on your part to make sure you’re not being played by solar contractors. And when I did find one whose numbers matched mine, I still did lots of homework. Every now and then I export data from my inverters into a free MS SQL database on my laptop and crunch the numbers to see if I ought to tweak a setting or two. That attention to detail is required to make it feasible IMHO. My inverters record telemetry in 5-minute intervals. I know at each point in time how much solar power was coming into each inverter, as well as how much power each inverter stored to the battery stack, pulled from the battery stack, and/or pulled from the grid, all to supply power to the electrical panels. I even now how much power was going to each arm within each of the 3 electrical panels.
But it’s worth it. In the past two years (since the EV and solar upgrade), the energy portion of my budget = what it was in year 2019 (the last year of Trump before the China virus distorted energy prices). What I pay now for a small power bill + a loan payment for the loan I took out to hire contractors for solar and electrical and HVAC and the water heater plus gasoline for what little we drive the gas pickup, is a hair less than what I was paying in 2019 for power bill + natural gas bill + gasoline for both cars. And the loan payment goes down as the balance is paid down (next year it’ll cost me less money). While the energy prices I mostly avoid goes up (next year I’ll save more money).
The most important part to me is being almost completely energy independent during 8 months of the year. I see it as practice runs for if the Dims use their Warmageddon cult energy policies to fully control us at mark of the beast levels.
