Brief marking notes / exemplars

• Full marks in calculations require correct use of P = V × I and energy estimate (Wh = W × hours). E.g., 20 W × 5 h = 100 Wh/day.
• Circuit diagram must show correct flow: panel → charge controller → battery → load; include regulator for 5V USB and fuse on battery positive.
• Safety: exposed terminals covered, correct polarity labeling, accessible disconnect switch, and weatherproof enclosures.
• Testing: include sample table of measured voltage/current across days and brief commentary on variations (cloudy vs sunny).
• Presentation: include photos or a short video; maintenance guide should list monthly checks (clean panel, check connections, battery health).
