Solar Energy: Large Scale Production

Large Scale Solar Energy Production

A typical system might look like this:

The key is to connect facilities to the power grid and sell power to the consumer at a competitive rate:

  • Current costs are about 25-50 cents per KWH for Solar Generated Electricity
  • Average price for the country from coal, hydro, nuclear, etc., is about 13 cents per KWH

De-Centralized vs. Centralized Mythology

  • Decentralized idea individual rooftops of homeowners and businesses decouple the community from the power grid

  • Centralized large facility in sunny climate is connected to the community via transmission lines (e.g. Eastern Oregon sends power to the Willamette Valley)

Because transmission losses are low (approximately 1% per 60 - 100 km) a solar PV facility that is within a few 100 km of the community is a more cost-effective investment than the decentralized model.


How Can Solar Large Scale Production Then Occur?

What Large Scale Facilities Are There?

California has 90% of the current world's solar electricity production!

How much is 370 Megawatts?

What about PV production facilities?

Conclusion: PV technology is likely to offer improved efficiency and lower manufacturing costs over time. If subsidies can be used to offset initial capital costs, then the price to the consumer becomes competitive.

Currently there is a big Marketing Problem with Electric Vehicles. Consumers simply won't buy them. Here are some attempted marketing strategies:
