One of those links claims:
Increased efficiency: At $6 per watt, the photovoltaic process is still an expensive method for producing electricity when compared to fossil fuels. The goal for solar energy is to reduce the cost to $1 per watt, which would make it a financially viable alternative energy source. One of the barriers in producing practical amounts of energy from sunlight is that less than 40% of the light that encounters a panel effectively stimulates the crystalline silicon semiconductors. Our nanoparticle treatment increases the UV conversion efficiency by about 30%, with vast potential for further improvement.
A watt is produced each second of time.
A watt is:
http://en.wikipedia.org/wiki/Megawatt#Megawatt
The watt (symbol: W) is the SI derived unit of power, equal to one joule of energy per second. A human climbing a flight of stairs is doing work at the rate of about 200 watts. An automobile engine produces mechanical energy at a rate of 25,000 watts (approximately 30 horsepower) while cruising. A typical household incandescent light bulb uses electrical energy at a rate of 40 to 100 watts, while the energy-saving compact fluorescent lights which are replacing them use 8 to 20 watts
How many solar panels equal 25,000 watts?
25,000 watts divided by 180 = 139 (rounded off to 140)
800 dollars times 140 = 112,000.00
That is abstract, or, illustrative of cost/benefit
One hundred thousand dollars worth of Solar Panels to power a car while cruising.
That does not compute to 'how many solar panels are needed to power an electric car' and that does not compute to 'how much does it cost to fill up my electric car with enough power to go 100 miles'.
An 800 dollar Solar Panel will pay for itself in the time it takes to produce 800 dollars worth of electricity.
Do you understand this fact?
180 watts per second creates a number of kilowatts per hour.
How many?
Because a joule as a quantity of energy does not have a readily imagined size to the layperson, the non-SI unit watt-hour, or rather its multiple the kilowatt-hour, is frequently used as a unit of energy, especially by energy-supply companies (electricity and natural gas suppliers) which often quote charges by the kilowatt-hour. A kilowatt-hour is the amount of energy equivalent to a power of 1 kilowatt running for 1 hour (3.6 MJ).
How about this:
How many 180 watt solar panels are needed to produce 1 kilowatt?
1000/180 = 5.55
800 times 6 = 4,800
For the cost of 5 thousand dollars a Solar Panel System can produce 1 kilowatt.
Suppose now that the System produces 1 kilowatt for 8 hours per day.
Suppose 13 cents is a current price for electricity per kilowatt hour.
Now suppose that a Solar Panel system produces electricity for 25 years.
365 days times 8 (hours) times 25 equals total production in kilowatt hours.
73000 hours
Times .13 cents = 9,490
See this please. Investing 5,000 produces 9,480, or, almost twice the cost of the Solar Panel System. This can be compared to a home mortgage in reverse. You borrow 100,000 for a home and 30 years later you pay 200,000 total in interest and principle.
You pay 5,000 to begin producing 1 kilowatt per hour and 25 years later you have produced 9,000 dollars worth of electricity (assuming the price of electricity does not go up or down).
Suppose the price of electricity stays the same for 15 years.
15 years times 8 hours a day and 365 days times .13 cents equals 5,695
After 15 years the Solar Panels have paid for themselves and the next 10 years (with a 25 year warrantee on the solar panels) are 10 years to save for the next system.
If the price of Solar Panels goes down and the output of Solar Panels go up, then, those 10 years can pay for a whole new system to create costless power.
15 years to pay for the System. 10 years to save for the new and better system. Costless power for as long as the new and better system lasts (compared to payments currently made to keep power flowing at .13 cents per kilowatt hour).
So...the investment in Solar Panels right now is better than any payments for oil POWER. You pay for gasoline. You do not invest in gasoline.
How about going back to the link where a person can get an electric car now?

Note: Sold out
LionEV currently offers two vehicles. The electric vehicle versions of the Hyundai Accent, and the Hyundai Tucson GLS. All of the comforts you have been accustomed to without the need for a visit to the pump. 100 to 400+ driving ranges depending on conditions and the core you choose. A complete charge on the battery core for each vehicle runs around $3.00 as of June 2007. Compare this to a full tank in the Accent at $36.00 and in the Tucson $45.00.
How do they come up with a 3.00 dollar cost for POWER?
From that site:
Power: 72+ kW , 110 HP Fuel economy equal to 114+MPG
How can that compute?
How about the FAQ?
http://www.lionev.com/FAQ_s.html
Yes, there is an onboard charger included with every vehicle.
Yes, we have completed at least one energy conversion test to produce an equivelent MPG rating for our cores. Track tests conducted on June 13, 2007 using the Ampmobiles S-10 truck resulted in an equivelent MPG rating of 114 MPG.
Yes, our battery packs are very compact. 6.174 KWh occupies a space of only 18.1 inches, by 15.7 inches, by 5.3 inches. Doubling the KWh does not double the size of the pack. For instance the only change to the pack in this example if you doubled the energy would be in the third figure, which would increase only 3.9 inches. This allows our packs to occupy the space presently used by fuel tanks and exhaust system components.
How does 6.174 KWh compute with 72 kW POWER?
How about division? 72 divided by 6.174 = 12 (rounded up)
12 batteries?
Full power for one hour? 24 batteries and full power to two hours?
Normal high constant draw is 600 Amps, constant draw normal is 250 Amps.
It takes about 9 hours to fully charge a vehicle's packs.
9 hours of charge and 3 dollars of charge?
How about 3 dollars of kilowatt hours at 10 cents per kilowatt hour?
300 divided by 10 equals 30 kilowatt hours.
Well...I sent an order for both cars to gain more information before investing the 1000 dollars deposit.
Here is something:
Our high end test mileage is 456 miles, the lowest test mileage achieved was 72 miles. That test was done while towing a 22 foot boat on a trailer. We probably would not have done as well if we had not put the boat on a trailer, but since we didn't catch any fish the day was pretty much a waste of time.
So...9 hours of charge (at an unknown rate so an unknown cost per kilowatt hour) POWERS a car for 72 miles at least and up to 400 miles.
For a taxi service, then, three cars can alternate on the charge and running as such:
24 hours a day divided by 9 hours charge time equals 2.7 (rounded up to 3).
No gasoline cost. Solar panels pay for themselves in time. No fuel costs.
