1.1 Costs of PV Technology Generations

AQ1.1.1 Costs of PV Technology Generations

1/1 point (graded)

(Note: due to requests from many students, to clarify the exercise and enhance the differences

between the two options, the efficiency of the first generation module was changed from 17%

to 18%. The correct answer to AQ1.1.3 remains the same as before).

We are going to build a PV system on a roof of 10m2, and we have two possible PV

modules:

(1) A first generation module with efficiency η=18% and cost of 0.80€/Wp.

(2) A second generation PV module with efficiency η=10% and cost of 0.40€/Wp.

The non-modular costs are 100€/m2.

Note that the irradiance under standard test conditions is 1000W/m2.

What is the cost in € of implementing a PV system for the entire roof using first generation

technologies?

2440

correct

2440

Explanation

Irradiance = 1000W/m2.

PV area = 10m2.

Module efficiency η=18%

Total PV output = 1000W/m2×18%×10m2=1800W

PV module costs = 1800W×€0.8/Wp=€1440.

Non-modular costs = €100/m2×10m2=€1000.

Total cost = PV module costs + non-modular costs = €2440.

AQ1.1.2 Costs of PV Technology Generations

1/1 point (graded)

What is the cost in € of implementing a PV system for the entire roof using second generation

technologies?

1400

correct

1400

Explanation

Irradiance = 1000W/m2.

PV area = 10m2.

Module efficiency η=10%

Total PV output = 1000W/m2×10%×10m2=1000W

PV module costs = 1000W×€0.4/Wp=€400.

Non-modular costs = €100/m2×10m2=€1000.

Total cost = PV module costs + non-modular costs = €1400.

AQ1.1.3 Costs of PV Technology Generations

0/1 point (graded)

If the power demand is 700Wp, which will be the most cost-effective (or cheapest) option?

(Note that for meeting the power demand, you may not need the whole roof area.)
