Sam Said:

Can solar power really be cost effective in the near future?

We Answered:

Solar energy is definitely an alternative to wasteful and harmful burning of fossil fuels. Now I will admit solar panels used to produce energy is a bit costly but in the long run it pays for itself by cutting your energy bill dowm drastically

How much does it cost to produce solar power in contrast to oil or power, per watt?

We Answered:

Solar power costs from $0.20 to $0.40 per kWH--the low end is for large commercial systems, the high end for residential ones. (first link)

A large solar power system costs about $9.00 per watt of capacity--roughly half of that is the solar cells, and the other half is land, support systems, grid connection, etc. (second link)

In contrast, fossil fuel generated power costs about $0.03-$0.06/kWh, and a fossil fuel plant costs about $1.30 per watt. Oil power would be the more expensive of this (coal is usually the cheapest), which is why...

Not sure if you know this already, but relatively little electricity is generated from oil. Only about 1.5% of electricy in the U.S. comes from oil powered plants. About 50% comes from coal, 20% each from natural gas and nuclear, 7% from hydro. See the last link for that.

How much does solar power cost?

We Answered:

joule is a unit of energy.

You need it per watt, unit of power. Reference has US$4-5 per watt for the panels, and for a complete installation about $8 to $12 per watt. This is the initial cost and installation costs.


reference:
The solar energy industry typically uses price per Watt Peak (Wp) as its primary unit of measurement. The prices for high power band (>125 watts) solar modules has dropped from around $27/Wp in 1982 to around $4/Wp today. Prices higher and lower than this are usually dependent upon the size of the order.

As a rule of thumb, the solar module represents 40-50% of the total installed cost of a "solar system". This percentage will vary according to the nature of the application. A complete solar system includes all the other components required to create a functioning system, whether it be to feed energy in to the grid or to be used in stand alone off-grid applications. In 2003, a residential solar system costs about $8,000-$12,000 per kWp installed.
