From Missouri USA. Live in the forest. Without solar power our electric goes off often! We have about 11 KW solar PV with an AC-COUPLED SMA system, grid tied with battery bank. We started out with also a Whisper 500 wind turbine on top of a mountain. It broke so many times we finally had a complete failure which was covered by warranty and then a second catastrophic failure just after Southwest Wind Power went bankrupt so it is gone with the wind;-). A $23,000 experiment gone. It made $900 in electricity over a four year period. Lucky thing we have a cell tower on our land where we get internet. The satellite internet with BOINC was a failure. I don't know if it works for some. Not with us.
