Solar and Wind Power Questions

I've been reading about solar voltaic and wind generator systems. The best book so far is The Complete Idiot's Guide to Solar Power for Your Home, by Dan Ramsey. I've also been reading back issues of Home Power Magazine, which is the best place to start finding out about solar and wind power. You can get an online subscription for $10 which allows you to read all their back issues.
There are some questions I haven't found answers to yet. Solar PV panels put out direct current, so you need an inverter to change direct to alternating current. To match your power company's 60 Hz current, your inverter has to be a synchronous inverter. Does your system's voltage have to match the power company's exactly? Any solar or wind system is constantly changing, so does the inverter also constrain the voltage? If so, does the constraint "chop off" any usable power above what the inverter needs to make exactly 240 volts? And are there any compatibility problems with the wind generator and solar panels, like say the sun is shining brightly but the wind is calm, or the wind is howling at midnight?

  1. Can anyone recommend the robust Remote Management & Monitoring program for a small IT service company like mine? Does anyone use Kaseya.com or GFI.com? How do they compare to these guys I found recently: N-able N-central support network
    ? What is your best take in cost vs performance among those three? I need a good advice please... Thanks in advance!

  2. Sorry to say I can't help you out. If it isn't made out of concrete or 2X4's, I'm lost.
    Good luck with your search.
