A 50W solar panel isn't all that costly (150-200$). This model is just a way to 'loan' these devices for consumers who can't afford even those. You will be surprised by how much utility these small capacity solar panels might provide even for those Indian consumers connected to grid (if they provide 2 lamps/ 1 fan as mentioned). This is because in rural areas, power cuts of around 8 hours/per day are very common.
