HOMEOWNER STATEMENT
Why solar? No matter how to cut it PV is a good idea. It’s good
for the environment, national security (stabilizes the grid) and
saves you tons of money. The better question is “Why not solar?”
I can’t think of any reason anyone wouldn’t want solar and
renewable energy. Let me know if you think of one.

HOME OWNER
STATEMENT
• East and West facing arrays • 15.4 kw System with Sharp
• LED and CFL Lights
• Automatic Solar Shades on
western exposure
• Shade trees planted near
the house on southern and
western exposures
We are in our mid-50’s and
decided to take advantage of
the green energy incentives.
After looking into the
options we felt that having
an annual net zero energy
bill for the next 25 to 30
years costing little more than
a moderately expensive car
would contribute greatly to
our retirement.

TOUR NOTES:
There is a gate to the neighborhood, but as HOA president, he will have
the gates open during the times of the tour. He has invited the installation
company to have a table at his house.
The tour will be in the front and side yard. He will have a table with
refreshments and flyers and brochures for the vendors that installed his system.
