Molokai’s Kualapu’u Public Conversion Charter
School’s recently-completed photovoltaic array of 187 solar panels.
The system will take the school’s electricity costs from upwards of
$10,000 per month to near zero.
KAUNAKAKAI, Molokai – On the Hawaiian island of
Molokai, time moves slowly and life is intentionally simple. Many
Molokai residents rely upon the fruits and vegetables they grow or
the fish they catch at sea to subsist as their ancestors have for
centuries. Additional supplies that cannot be grown or acquired from
within, arrive with a high price tag from the U.S. mainland via
Oahu, urging most individuals to think locally.
This idea of self-sufficiency overlaps with the increasing use of
photovoltaic systems across the island. The technology employs
island companies and reduces the necessity of importing foreign oil
and gasoline (which costs, on average, almost $5 per gallon on
Molokai) from the mainland.
Just last month, Molokai’s
Kualapu‘u
Public Conversion Charter School, which has an enrollment of
more than 90 percent Native Hawaiian students, completed the
installation of its own PV powerhouse.
With a 50-kilowatt inverter and 189 total panels, the school will
now be more self-sufficient – putting an end to its once
$10,000-per-month electricity bill.
“Financially it makes sense,” Kualapu‘u Principal Lydia Trinidad,
Native Hawaiian said. “On Molokai, I think we have the highest
electricity costs in the islands.”
Trinidad said that due to the island’s relative isolation, the
island lends itself to being more self-sufficient. Tourism,
agricultural production, the housing market and economic growth on
the island are minimal. Molokai receives the fewest tourist visits
and dollars of any typically-visited Hawaiian island. Attempts to
develop a major theme park and resort now showcase boarded windows
and empty streets. Former pineapple plantations and cattle ranches
are now vacant. Vacant multimillion dollar homes that now dot the
island’s west end stay on the market for months unable to be sold.
“We’ve had situations when the barge hasn’t come in and we’ve had no
supplies, no toilet paper, for example,” Trinidad said. “So,
sustainability is a theme that is island-wide.”
Trinidad said the school began to develop the system in 2008 when
oil prices skyrocketed to nearly $150 per barrel driving electricity
costs to almost $10,000 each month. The school directors saw the
reality of making a choice between educational services and
electricity bills.
“We thought, ‘we have to do something about this,’” Trinidad said.
So the school contracted with ProVision Solar of Hilo to install a
PV powerhouse. ProVision President Marco Mangelsdorf explained that
the school is operating on a net-metering basis with
Maui Electric
Company. When the school is not using all of the solar
electricity generated from the system, the excess is accepted by the
local utility company.
Rather than paying the school for this surplus power as is the case
in other U.S. states, the school is issued energy credits that can
be used on days when the school needs to draw energy from Maui
Electric Company. The surplus kilowatt-hours (kWhs) are credited to
the school at the current retail rate, which in November was about
34 cents per kWh.
According to the recently-approved decision and order by the
Hawaii Public
Utilities Commission, ratepayers across most of the state
(except for the island of Kauai) now have the option to be paid for
their surplus power. However, in this type of agreement, the power
company pays back to the provider a significant amount less than
what it charges (18.9 cents per kWh). Energy producers also have to
pay an application fee of more than $200 and a $25 per month service
charge to participate in the program.
This inequity in the utility company’s docket is similar to
fledgling alternative energy charters in other states that have
since been updated and brought into line.
The public school is home to approximately 400 pre-kindergarten
through sixth grade students and offers a Hawaiian
language-immersion program in which the students learn their core
classes in Hawaiian. The school receives part of its funding from
the Kamehameha Schools Administration, which operates across the
islands with the goals of nurturing Native Hawaiian culture and
growing schools with predominantly Native Hawaiian students. The
Kualapu‘u School places educational emphasis on the cultural
experiences of a rural community.
Trinidad said it is the school’s plan to integrate curriculum about
the photovoltaic system into the classroom topics so the students
will understand where their energy is coming from.
“First, they just have to know what it is and that some of their
energy is coming from the sun.”
Trinidad explained that the implementation of solar power at the
school directly parallels the Native Hawaiian traditional belief
that the islands provide everything necessary to exist.
“I believe that this Native Hawaiian value is a universal value of
using all the gifts that have been given to you. PV is a gift – a
modern-day gift – the sun is a gift and we have to use this
technology that we have been given.”
