Torresol Energy provides solar energy night and day

We have as much sun in south Georgia as southern Spain, where they're building industrial scale solar plants.

Torresol Energy has overcome one of solar energy's biggest challenges: operating when the sun doesn't shine. The 19.9 MW Gemasolar concentrated solar power plant in Spain's Andalucia province has two tanks of molten salt (MSES) that store heat energy generated throughout the day. Unlike normal plants that have less thermal storage or none at all, this stored energy enables Torresol to satisfy peak summer energy demand long after sunset.

So we already know how to store solar power, even without developing better batteries. There's more in the article. About that plant:

Characteristics of Gemasolar:

• Rated electrical power: 19.9 MW
• Net electrical production expected: 110 GWh/year
• Solar field: 2,650 heliostats on 185 hectares
• Heat storage system: the molten salt storage tank permits independent electrical generation for up to 15 hours without any solar feed.

185 hectares is about 457 acres, or about one VLCIA industrial park.

Seville, Spain, is about 37 degrees north latitude. We're at about 31 degrees. In other words, Seville is about 360 miles north of us. And we get about the same amount of sun as Seville does.

The average insolation (amount of sunlight falling on the surface) in Seville, Spain is about the same as in Valdosta, Georgia: about 4.85 kWh/m2 per day.

Here's a month-by-month comparison using Solar Electricity Handbook 2012 Edition. They haven't heard of Valdosta, so I used Macon. You remember Macon, where it was 110 degrees June 30^th.

When	Jan	Feb	Mar	Apr	May	Jun	Jul	Aug	Sep	Oct	Nov	Dec
Seville	4.16	4.76	5.68	5.81	5.98	6.49	6.90	6.77	6.01	4.78	3.96	3.63
Macon	3.76	4.24	5.03	5.52	5.58	5.16	5.24	5.07	4.84	4.96	4.18	3.73

Some months, Sevilla has a bit more sun. But in part of the fall, we have more sun.

Maybe we should start thinking bigger around here. And if we've got the sun for a big solar plant, we've got the sun for a lot of little rooftop solar panels. How about if we put Valdosta, Lowndes County, and south Georgia on the solar map so everyone will hear of us?
