Transcript of Kapolei Solar Project

title History How PV panels work Inquiring minds want to know... How in the heck does solar power work? Well... Solar Power is in our Future Doping? The process of intentionally introducing impurities into an extremely pure semiconductor to change its electrical properties. DOPING: What does doping do for PV Panels? Doping allows the panels to more efficiently conduct Direct Current Electricity. You may be saying to yourself...
"I am here to learn, tell me how!" Direct Current Direct Current Alternating Current Alternating Current COMBINER BOX:
Combines the DC electricity from the various solar panels. Solar Industry Lingo 1. MODULE = Solar Panel Pop Quiz! What is it called when you combine the power of several batteries together in series. Like This... What is it called when you combine the power output of two or more batteries by putting them in series?
Like this...... + +
+ - -
- - Need a hint? DAISY CHAIN 2. STRING:
Two or more PV modules daisy-chained together. 3. SOLAR ARRAY:
General term for the solar installation as a whole.

For example:

"There are (2) strings of modules in our solar array." Direct Current (DC) Alternating Current (AC) Any battery-operated equipment:
Trolley Cars Transmission Lines
Electrical Outlets
Household Appliances A power converter was invented to convert AC power to DC power But we need to change DC power to AC power!

What do we do? Flip the same power converter
around AC Power AC Power DC Power DC Power The Power Conversion DC to AC Power Inverter AC to DC Power Converter And how does this Power Inverter work you ask? Power Inverter Schematic Any Volunteers to explain this process? What is the difference between
DC & AC Power? Amplifiers,
and Optoisolators...
OH MY! (2) Strings (8) Modules (1) Array The Bottom Line is that you need power inverters to change the DC power that is produced by your solar modules into the same AC power that is distributed by your electric company. Topics to Cover Past, Present, & Future of solar power

Magnifying Glass was used to concentrate the sun's rays to create fire and entertain. 1839
French scientist Edmond Becquerel discovers the photovoltaic effect.
<1% efficiency achieved 1954
Silicon photovoltaic cell first developed at Bell Labs.
4% efficiency achieved 1959
Hoffman Electronics advances PV cell efficiency.
10% efficiency achieved 1985
University of South Wales advances PV cell efficiency.
20% efficiency achieved 1994
The National Renewable Energy Laboratory advances solar cell efficiency.
30% efficiency achieved 2009
Spectrolab advances solar cell efficiency.
40% efficiency achieved What does that history add up to? So efficiency is up...

What about prices? Current commercial efficiency is approx. 20%. And experimental panel efficiency is expected to be 50% efficient by 2011. Panel prices are expected to decline by approx. 40% over the next 3 years. Contributing Factors... 1. The Credit Crunch!
Due to the tight financial markets, there has been less money to invest in solar installations. Due to this fact, panel manufacturers now have a surplus of stock. 2. Silicon Supply Gains
It is expected that world silicon supply will quadruple by 2012. This excess supply of silicon in the market will bring down the price of silicon panels. System Statistics # of Modules on office building 138
# of Modules on storage building 236
Total # of Modules 374

Peak Module Power (DC) 72 kW
Peak Power Demand (AC) 70 kW Examples of Captured Information.... 1. Time-Lapse Photography
2. Close-up video
3. Close-up Photography
4. Time-Value Analysis
5. Careful Notes The new PV systems are more efficient...

and the materials costs less...

So demand for the systems should go up? Project PV Module Revenue 2009-2013 How do we know that the savings is being realized?

The Sunny Webbox, of course! Camera 55' Wood Pole Time-Lapse Video # 1

Storage Facility Time Lapse Video #2

Office Building Close up Video Examples Why else is it a good time to buy solar? 30% Federal tax credits

35% State tax credits (Hawai'i)

State incentives (Hawai'i)

Depreciation Expense

Utility Credits The bottom line... The solar market is a market with years of expansion ahead of it. The Kapolei Facility Solar Project will be a financial benefit to the company as well as a solid entry into a new market! If we can just capture the knowledge gained from the installation. DC Power like
BATTERIES! Solar Industry Revenue Revenue
(in Billions) Year 33% increases in revenue are expected through 2013 Challenges With a solid plan to enter the market,
Henkels & McCoy can set itself up for success. Non-union competition Unfamiliarity with the market Work with the unions to create parity with non-union contractors Target suppliers with which to partner Identify & utilize efficiencies within H&M that the competition does not have Take Aways... The solar industry is an emerging market Solar is not as complicated as you might think Henkels & McCoy is striving to share information company-wide and become a learning organization And the # 1 take-away is...
