The cells in a solar module are wired (mostly) in series.  This is because:

If the Zenith angle is 60 degrees, what is the AM number?

What is the name of the international protocol that requires countries to reduce emissions ozone depleting substances?

What is the name of the angle relative to vertical to describe the position of the Sun in the sky?

What was the capacity of the solar panels installed on the first satellite launched with solar cell technology?

What is the order in which PV technologies have evolved?

What is the energy level of a  photon with wavelength 0.5 micro meters?  Given your answer in eV (write the unit in the answer) accurate to at least one decimal point.

The Fermi-Dirac distribution helps us to explain what phenomenon?

When p- and n-type doped silicon are brought together, what happens?

Download the LCOE_simple_examples file from the Moodle folder.

Modify one of the tabs in the spreadsheet to calculate the LCOE for a rooftop system with these details:

• Assume zero installation time, e.g. generation starts in the same year as installation.
• System size is 7.5kW
• Capital cost is $7000 minus a rebate of $40 per MWh for the generation over the next 5 years, assuming a 0.2 capacity factor
• assume a lifetime of 30 years with no degradation of the panels

i) What is the total capital cost? (2 marks)

ii) What is the LCOE in cents per kWh?  What is the LCOE in $/MWh? (6 marks)

iii) How does this compare to retail tariffs?  Does it look like a good investment? (2 marks)
