Unique Solar

I am an retired electronics engineer that decided to have a
solar photovoltaic (PV) power generation system (hereinafter called ?solar
system?) installed on my south facing second story roof.  I researched
reputable companies that install solar systems and decided to get bids from
SolarCity, ASI Hastings Heating & Air, Palomar Solar, Sullivan Solar Power,
and Unique Solar.  All these companies were very professional in their
sales approach to me, and all were technically knowledgeable.  All the companies, except SolarCity, provided
sufficient contract detail to allow a good comparison between the proposed
solar systems.   I feel any of these companies would have been able
to successfully install a solar system meeting my needs, and my decision came
down to what I technically desired and the cost.
 
As the solar contractors will clearly explain to
their customers, there are basically three types of solar systems: (1)
microinverter, (2) string inverter, and (3) string inverter with power
optimizer.   ASI and Palomar Solar install microinverter solar
systems, but not string inverter solar systems.  SolarCity and Sullivan
Solar install string inverter solar systems, but not microinverter solar
systems.  Unique Solar installs all three type of solar systems, based on
what is best for the particular customer.  Each of the three solar systems
have unique advantages and disadvantages.  The companies that install only
one type of solar system will clearly point out the disadvantages of the other
type of solar systems, but not so much the disadvantages of the system they are
trying to sell.  Choosing which solar system configuration to install
involves a fair amount of research, and personal preference.  For me, I
decided I wanted the microinverter solar system because I wanted to monitor the
individual power generation of each solar panel.  This decision allowed me
to narrow the contractor I would use to ASI, Palomar Solar, or Unique
Solar. 
 
It turned out that the decision was fairly
simple.  All three companies proposed identical solar systems, i.e., LG290
solar panels, Enphase M-250 microinverters, Envoy Gateway, all the drawings,
permits, etc..  It was interesting that the ASI and Palomar Solar total
contract price differed by only $150.  Unique Solar came in significantly
less than the ASI and Palomar price, so I decided to sign a contract with
Unique Solar.  I did upgrade the solar panels to the LG295 from the LG290,
for a total contract increase of $200.
 
The owner of Unique
Solar is Ulf Waldmann (858.353.7478) and is the person I met
with initially and throughout the installation process.  Mr. Waldmann was
professional, very knowledgeable in solar panel and inverter technologies, and
provided the greatest detail on what I call the solar system ?POA&M? (plan
of action and milestones) of the three solar contractors.  I think the
information provided by the other contractors was adequate for most customers,
but I tend to like more engineering detail.  Since the solar panels are
likely be operational for 25 years, I wanted to re-roof where the solar panels
were being installed in order to ensure my roof would not leak for the 25
years, vice the 10 year warranty provided by the solar contractors. 
Without any involvement from me, Unique Solar and RC Roofing (Rick Clark; 858.337.6908)
coordinated a schedule between them where the old roof would be removed by RC
Roofing, the stanchions (used to mount the solar panels to the roof) would be
installed by Unique Solar, and then the new roof would be installed by RC
Roofing.  The re-roofing job was accomplished without a
problem.   Mr. Waldmann kept me informed of all events that went on,
and there were no surprises in the solar system installation process or the
payments requested.  I was also pleasantly surprised with the
craftsmanship of the solar system installation, e.g., end caps on the rails,
the conduit being grounded properly and straight, and cable routing.  The solar system installation took less than
six weeks from the day the contract was signed to the day the installation was
completed.
 
The City of San Diego inspected the solar system
installation on 24 March 2014 and signed off on the inspection record with no
problem.  The San Diego Gas and Electric company gave permission on 25
March 2014 to activate the system.  My solar system is now up and
operational, and I am able to easily and remotely monitor all parameters of the
system.   In summary, I recommend Unique Solar without reservation.
