Your math is faulty here, as the solar panals do not produce 80 watts per year.
If I am not mistaken, they produce 80 watts per hour or 350,400 watts per year assuming an average of 12 hours of daylight per day.
The math may be faulty, but so are the claims for the solar power. The 80 watts per hour are under ideal conditions--noon on a sunny day. Morning and afternoon, they produce a lot less unless they track the sun. If they do track, there is still a loss as the light goes thru a thicker atmosphere when the sun is low. And if they are located at higher latitudes, their efficiency is reduced, again because of low sun angles. Furthermore, after a lot of careful research, I have noticed that there are cloudy days now and then.
Solar is coming along and in a few years they will have more efficient cells, but the only arguments I see for solar electrical generation now are to provide power in remote locations and to fund a budding industry that can only get by with subsidies. And that second argument, I don't really like.
OTOH, solar water heating is a different story and I think we should encourage that economically, thru subsidies or other means based on solar efficiency for a site or an area--more so for SoCal and Arizona than western Oregon.
