These are just cheap Chinese panels. You do realize that to get stable electricity working you need a shitload of other expensive stuff? Batteries and all the controlling electronics etc. Solar power is not cheap, it's one of the most expensive ways to get electricity at the moment actually. People that go for it are mostly interested in being "off the grid", doing a fun tech project, and trying to be eco-friendly. No one in their right mind switch to solar power to save on electricity bills, cause solar is way more expensive than other sources in most parts of the world.
So true and like you said, mainly off-grid cause is stupid going solar if you pay less than $0.20 per khw but i guess some people will never understand what you said because for them once they break even they get free power which is a lie cause there a constant maintenance for that electricity and in the end is tends to be a lot more expensive than most power providers offer and a lot more work, mining is the same thing, too much work for peanuts right now, why mine while you can buy coins cheaper than you would pay to produce, these prices will not last long cause the people selling right now are losing everytime they sell/cash out for usd or other currency.
Don't spread FUD.
If your'e scrappy and hustle you can get an 8kW array (US or EU panels) with hybrid inverter + mounting for $8000 USD. The battery depending on chemistry will be another $2000 - $6000 - also factoring in sizing, depth of discharge, etc.
Theres no maintenance if you install properly, maybe occasionally dusting off the panels if your climate is like that.
The payback ~2 years at 95%+ utilization if you're paying $0.10/kW from the utility
