(25)

SOLAR PV

Technology Background

• Converting light to electricity first discovered in 1830’s

• Solar panels contain cells made from silicon material to convert sunlight to electricity

• DC power travels through an inverter to change to AC power

• Interconnection agreement required to connect to grid

(26)

Solar PV

Major drivers in the solar market

• Tax incentives (continuing through 2016)

• Utility incentives

• Enthusiasm of customers for green energy, especially solar (coolness) • Customers desire to reduce dependence on foreign oil

• Local electricity tariffs: High electricity rates encourage alternative sources of energy • Sunlight conditions: Solar electricity prices fall as sunlight levels increase

• Marketing strategies by solar companies

• Delivery infrastructure, which is the number of local suppliers and qualified installers • System prices are dropping

• Increased imports from China • Economies of scale

• Technology improvements

(27)

SOLAR PV

What happens to the energy I generate?

• If you are producing more than you are consuming, then the excess energy goes to the grid. Conversely, if you are consuming more than you are producing, then all of your generated energy is being consumed by you, and any additional energy requirements you have will be provided from the grid (i.e., in-flow kWh)

• The figures in the next slides illustrate two basic scenarios for power flow between the DRG, customer's facility, and the grid
