Subtropical latitudes in continental US markets, you're looking at like $2/yr/sq ft of value for the power output.
I'd want solar panels for like $5/sq ft installed, expecting 10 years of life.
It's going to cost $1000 minimum to install, so the panels need to cost $2/sq ft x 300 sq ft to make this worth it. $1000 to install 300 sq ft + inverter and electrical panel upgrades seems light but might be reasonable we'll go with it.
Larger than a balcony, but maybe in the realm of possibility for a roof.
Right now solar panels cost what? $10 per square foot? Have they reached the physical limit of economic production/storage/transportation at $10 per sq ft or can it go lower?
(Let's not get into battery micro-storage economics).
- wing-_-nuts 6mo agoWhen you consider your other option is a whole house generator which sits idle 99.99% of the time, requires regular maintenance, vs the fact that a solar / battery setup is providing resiliency AND lowering your power bill every month, it seems like solar / bat is a no brainer. Your money, your choices, but I know which one I'm doing when I get a single family home.
- engineer_22 6mo agoFalse dilemma. There are other options.
- wing-_-nuts 6mo agoSuch as? I've looked into the options, you can either get a whole house generator, which suffers from all the issues I described, or get a solar setup. I suppose if you lived by a stream you might be able to hook up a microturbine for hydro but that's very situational. Cost is not the highest deciding factor for me. The resiliency renewables grant you would be worth it even at a premium
