On Aruba, the costs per KwH calculated in 2012 is AWG 0,47. If you are a home owner, commercial property owner or owner of an industrial building on Aruba, please have a look at your electricity bills and calculate the average amount of KwH you use and the money you spend on electricity per year.
In the calculation below you can see how many solar panels are needed to generate the same electricity you are using now. The cost price for the needed solar panels are added to the appropiate inverter and come to a total package price including assemblage on Aruba.
In the calculation we are referring to 250 WP solar panels, each generating 500 KwH in the Caribbean, measuring 1520 mm x 1038 mm x 34 mm on a pitched roof. Furthermore we have considered the fact that the average yearly price ingrease for electricity on Aruba is 6%.
As you can see the more electricity usage you have, the faster you will earn back your one time investment. Many banks already offer so-called "green loans", financing the purchase of your solar system on Aruba for a monthly installment that may be even lower than the monthly price you pay for electricity now.
Evendo the calculation below is as up to date as possible, it is still an indication. Please don't hesitate to contact us for a free and exact price estimate of the solar system needed for your personal requirements.
SOLAR ENERGY ARUBA
We've used the Sun for drying clothes and food for thousands of years, but only recently have we been able to use it for generating power. The Sun is 150 million kilometres away, and amazingly powerful. Just the tiny fraction of the Sun's energy that hits the Earth (around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over.
In fact, every minute, enough energy arrives at the Earth to meet our demands for a whole year - if only we could harness it properly.
Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity.
The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce.
