"Here comes the sun!" Host Kevin O'Connor and plumbing and heating expert Rich Trethewey talk with solar expert Tom Huntin about letting the sun's rays power your home. Plus we flash back to 1983 for a look at "The All New This Old House."

Solar ELECTRIC panels are anywhere from $3.30 to $5.00 / watt. You can figure on getting 3 to 4 hrs of FULL sun / day unless you are in Arizona or southern Calif and even then they need to be angled into the sun (not horizontal like when driving down the road).
I run my house (cabin) on 200w of panels and use about 500w/ day. I have 600ah battery bank (6 200ah golf cart batteries)
What I really want is a 100 to 200w sterling engine I can mount in my woodstove!
Your generator should put out more power. Either you should get a DC generator or an inverter. Another alternative is another alternator (with solinoid)under the hood that is designed for charging batteries.
