  15. 15. The wisdom of hindsight: What you learn if you really look and listen … 14 # Observation ‘Insight’ Design Principle 1 What people really need 
 is radio and TV, not light. Demand for electricity is way 
 higher than just for lighting. Solar panels must be big enough to power larger appliances, such as televisions. 2 No (banking) infrastructure to save up money and houses can’t be locked. Money has to be spent 
 the moment it is earned. Monthly payment options 
 are a core requirement. 3 Belongings are well-kept 
 and respected. Private property is better 
 maintained than rentals are. People need the feeling they 
 actually own their solar panels. 4 Existing PV solar are 
 often non-functioning. No supportive infrastructure? 
 » People won’t maintain their solar panels. Maintenance infrastructure 
 on-site is key to success. A selection of collected observations, user needs, insights and derived design principles
