Exercise 2 solution

Example record for a south-facing patio:
Morning (9am): sun on the left half, shade from the fence on the right.
Midday (1pm): full sun across the patio.
Late afternoon (5pm): sun on the right half only; the house shades the left.
Total direct sun: roughly six to seven hours in summer (check in other seasons).
Shelter: wall on one side, open to wind on the other, so use a windbreak.
Water: outside tap about four metres away.
Verdict: suits fruiting crops such as beans or tomatoes in pots, provided the pots are watered often.
