Got a bad roof for climbing around on, here's a few ideas:
1. Put the solar panels on the ground, porch, garage, dog house, etc.
2. Put the solar panels on the neighbors house or in the neighbors yard.
3. Put the solar panels on open ground on the edge of town by investing in the community solar farm.
4. Have all the people on your street get-to-together and rent a high-lift platform and wash all the solar panels on the street or community in one day. Community picnic to follow.
5. Hire the neighborhood, out-of-work, out-of-school, teenager to get up on the roof.
6. Get a building contractor to construct a opening in the roof just above the solar panels. Go up through the attic, stand in the new opening and clean the panels. Hose and long handled, soft broom needed.
7. Don't wash the panels. The heck with Begley. Just how dirty can a solar panel get while sitting on a roof 40 feet off the ground? No dusty roads around, right! The panels will still be making clean energy even if you don't manage to clean them.
There you have it - my response to Tom's five things that are disadvantages of solar Power. I bet Ol' Tom was just kidding, he just wanted to get people like me stirred up a little. After all, the more we think and learn about Solar Power, the better it gets. Net-zero is good, one of my goals, and solar power will play a prominent role.
