Hi @gailly, thank you for participating in the Basic Electricity Homework. We have assessed your Homework post , and the below captures our assessments.

---

A. Your assumption about solar power is correct. In short, solar power is renewable energy that protects our earth from pollution. Through solar power we can reduce the financial cost of the family. Very Good (0.5 Marks)

B. The differences between AC solar power and DC solar power are correct. You have written the key differences. (1 Mark)

C. Your home has loads of electrical home appliances. Hopefully you can calculate a customer's home load. The objective of our homework this term is to know how to calculate the customer's electrical load. Hope you succeed. Very Good (1.2 Marks)

D. You have provided a battery of 500 AH to build a DC solar system. I think it will take more time to fully charge such a big battery with your 250 watt solar panel. Hope you understand. Very Good (3 Marks)

E. Your specification for your 1HP pump motor is correct. But I suggest you if you have internal charger controller in inverter then additional charger controller is not needed. Hope you understand. Very Good (3 Marks)

• A better homework would be to draw a block diagram while you write your description of solar.

• You have calculated the load of your home electrical home appliance in watts. But you didn't convert to kilowatts.

• We are very happy to see your knowledge about solar power. We want each of our students to create a solar power project through homework and lessons. Good luck to you.
