Hi Ray, Robin and I would like to commend your company, Sustainable Energy Group, for the excellent service from start to finish. The installation of our solar system is clean, was completed on schedule & is a very nice addition to the value of our home. Along with your energy savings suggestions that came with your energy analysis, our pay back on cost will be approximately 5 years. Our PG & E bills are down approximately 50%. We are Happy customers! Thanks Again, - Mike and Robin Bratton |

Our hats
off to Sustainable Enery
Group. They made the
experience of installing GREEN technology a pleasure.
Their
proposal was professional. The installation was
professional. And the follow-up was
professional. The solar
system looks and functions great! Thanks again Ray! - Michael and Lotus Hallenbeck |

Jim and I love our new solar panels and
appreciate the resulting
savings we see each month on our electric
bill!
I’ll admit we had
serious
concerns about putting out the money
for the panels, reservations about just how much it
would really save
us on our electric bills, and if it was something we
could afford to
do, but all that has been set aside as we gleefully
welcome our new
relationship with PG&E’s net-metering program and
the resulting
savings we see each month on our bill. This
monthly savings,
along with the federal tax credit we just applied to our
2010 tax
filings and our reduced impact to the environment, has
convinced us
that we made the right decision.
We interviewed two other
solar
contractors and even one that
leases the panels to find out as much as we could about
the process,
the savings, and obtained bids for the size of service
each estimated
to meet our needs. While the prices seemed
competitive, none of
the other contractors came even close to being as
thorough as you were
in explaining the program to us in terms we could
understand,
estimating our savings compared to our cost, completing
the
installation of the panels we chose, and taking care of
the details for
us with PG&E. We were especially
impressed with how you
took the time to evaluate our energy use habits,
inspected our home for
energy leaks, and showed us how we could further save
with energy
conservation. We continue to appreciate your
contribution
to energy conservation by the informative and
interesting articles you
write for the Union newspaper.
We have never regretted
our
decision to install our solar
panels or our decision to engage your company to install
them for
us. You gave us great service, great advice, and
completed the
installation in a professional manner.
Please feel free to
use our name as a reference for your service and for
Sustainable Energy
Group.

I was so pleased to have chosen Sustainable Energy Group to engineer and install my solar photovoltaic and hot water systems. Ray Darby is a wealth of knowledge and experience and his installation was clean, precise and compentently engineered to meet our criteria. Four years later (April 2011), the systems continue to work flawlessly. In the process, Ray has become a friend. - JeannieTofanelli |

When shopping for solar, we met our
match in Ray
Darby. He answered our many questions, introduced us
to the
micro-inverters uniquely designed for sites like ours,
provided a
clean, professional installation, and spent hours
exploring options for
energy savings in our home. In addition, Ray is easy
to work with and a
nice guy. He has our recommendation. - Mike and Leila Barber |
