Overview of Solar

Solar energy is the cleanest source of energy on the planet and currently makes up less than a tenth of 1% of all US electricity generation. HelioSage is changing this.

As with all new technology, solar energy generation began with tremendous expense and spotty results - that is, it took a lot of money to generate a small amount of electricity. Fortunately, the technology has advanced dramatically. Panel and module prices are continuing to decline, and the efficiencies of these systems continue to improve at a stunning pace.
 
A Quick Primer in Solar Technology
There are three types of solar energy systems (see the diagram below):

1) Photovoltaic (PV) offers three different generations of PV technology
    a) crystalline silicon solar cells
    b) “thin film” solar cells
    c) nano PV technology.

2) Concentrating solar power that comes in two forms: PV (a.k.a. CPV), and solar thermal where the sun heats up a heat exchange fluid, which in turn powers an engine.

3) Solar water heating, which uses a number of different solar technologies to directly heat water in homes and businesses.

 
In one year, a megawatt of solar:
  • Produces enough energy to drive a car 2,480,000 miles (99 times around the equator).
  • Produces 1,500,000 kilowatt hours of power.
  • Saves $150,000 in billed energy use.
  • Prevents 1,162 tons of CO2 emissions.
  • Prevents the burning of 1,500,000 pounds of coal.

Solar Supply Chain

Long before HelioSage commissions a solar energy system on a rooftop, or as a shaded structure on a parking lot, or on land nearby a corporate headquarters, many companies around the world come together to produce the raw materials and parts of the solar energy system.

Basic Energy Numbers

Watts:
  • 1,000 watts = 1 kilowatt (kW)
  • 1,000kW = 1 megawatt (mW)
  • 1,000mW = 1 gigawatt (gW)

Average Electricity Costs (per kW):

  • VA = $0.07
  • CA = $0.15
  • HI = $0.22
  • NY = $0.16
  • NC = $0.07
  • MD = $0.12
  • FL = $0.10
  • AZ = $0.08

Historical Cost of PV/watt

  • 1970 = $200/watt
  • 1980 = $22/watt
  • 2000 = $7/watt
  • 2007 = $2-3/watt

Gen1 PV - thick film

  • 10,000 sq. ft. roof = 100 kilowatt solar energy system
