CommunityCommunity
KahuluiIt is our home; our ainaIt is also small enough to be a good place to test our system.

Why Did We Choose Solar/Wind Powered Golf
Carts? First we thought of using biomass as fuel,
but the conversion plants did not seem practical.
Then we thought of pedal powered or assisted energy, but the conversion of the available golf cart was mechanically too complex to complete in time.

Why Did We Choose Solar/Wind Powered Golf
Carts?We also had a golf
cart ready for us to convert
The solar technology to convert golf carts is available

Solutions to Charge Used solar & wind energy to
run and power our system Chose solar and wind
energy because Maui is usually sunny and has trade winds
Free energy resources

Creating and storing energy during the day
Using Maui Electric Company’s grid “deposit & withdraw” energy

Photovoltaic cellsChanges sunlight to energy -absorbs energy from the sun to
semiconductor-then, electrons move around, which is called a current-when metal is put near this current you can pull current or energy out of the PV cell

Vertical Wind Turbines
Using vertical instead of horizontal to save more space
More vertical wind turbines around the stations to create more energy
They are also much quieter.

Positives of SPA SystemEquipment is expensive. For
instance, a finished SPA would cost from 8 to 10 thousand dollars, BUT it’s cheaper than maintaining a gasoline car.
Convenient locations for charging and eventually Kahului residents will purchase their own.

Assorted Sizes
Multiple sizes to accommodate all groups.

Actual Outcome of our Project
Sunetric sponsored us so we were actually able to create a prototype of the SPA.
They are also going to install a PV system on our school, which will make us more eco-friendly and save us money.

Actual Outcome of our Project
We will also have meters that we can use to run all kinds of solar related science projects….
how exciting!

We were able to share our SPA solution with the community at our SCC night and our
presentation to Mayor Tavares.
