✍️ Sample SE ENGR. Questions & Answers
1. Across their life cycle, how do the greenhouse gas emissions of crystalline silicon PV typically compare with coal generation?
Harmonized LCAs, such as NREL's, put c-Si PV at tens of grams per kWh, compared with roughly 1,000 for coal.
2. Designers commonly limit DC circuit voltage drop to about what level to keep losses low?
Keeping DC voltage drop to about 2% (within an overall budget of 2–3%) is common practice, even though the NEC does not require it.
3. A commercial customer uses a BESS for peak shaving. Which utility bill component does this primarily reduce?
Peak shaving lowers the maximum kW drawn, which sets demand charges.
4. Why are unglazed polymer collectors commonly used for swimming pool heating?
Pool water is only slightly above ambient, so optical efficiency matters more than insulation and unglazed panels excel.
5. What is the primary cause of attenuation of solar radiation as it passes through the Earth's atmosphere?
Solar radiation is attenuated primarily by absorption from gases (O₂, O₃, H₂O, CO₂) and scattering by aerosol particles and cloud droplets as it travels through the atmosphere.
6. A solar project has BAC = $10M, EV = $4M, and AC = $5M. What is the cost variance (CV)?
CV = EV − AC = $4M − $5M = −$1M, meaning the project is over budget.
