The Green Fight: Solar Panels vs. Trees

We’re supposed to save trees – not only because there are laws against cutting them, but it’s the right thing to do. So Sunnyvale couple Richard Treanor and Carolynn Bissett were doing a good deed by planting a bunch of redwood trees between 1997 and 99.

Their neighbor, Mark Vargas must also be environmentally conscious, as he installed solar panels on his roofs in 2001.  There’s only one small (actually large) problem: solar panels don’t work without exposure to the sun.

The redwood trees grew to be giants, some reaching 400 feet, and they cast a shadow on the solar panels.  The neighbors have been fighting for years and finally Vargas filed a lawsuit.  Last December a judge ordered the couple to remove the trees. They won’t appeal, as after spending $37,000 in legal bills and can’t afford the lawsuit anymore, so they will abide. 

The lawsuit, and decision was based on California’s Solar Shade Control Act, which requires homeowners to keep their trees or shrubs from shading more than 10 percent of a neighbor’s solar panels.

Now, here comes the controversial part:

Existing trees that cast shadows when the panels are installed are exempt, but new growth is subject to the law.

CA state Sen. Joe Simitian (D) of Palo Alto plans to change it.  The bill he introduced this week would protect trees that were planted before the installation of solar panels. Those planted next to already existing solar panels would still be subject to removal.

Here’s the NBC11 video.

Update:  2009-10 will be the perfect time to install solar, as supply is expected to exceed demand.
