“Progressive Purchase” is a new pricing model developed by Simpa Networks that shares some characteristics of the familiar “prepaid”, “pay as you go”, and “installment plan” pricing models. Under Progressive Purchase, the consumer makes a series of payments, each of which unlocks the solar home system for a paid amount of energy consumption (Kwh). Once the prepaid consumption is exhausted, the solar home system is temporarily disabled until another paymenmt is made. Once the consumer has fully paid the total purchase price of the product, full functionality is restored and the product is permanently unlocked.
The Progressive Purchase pricing model is enabled by the Simpa Regulator, a tamper-proof, system-integrated micro controller and user interface that regulates the function of solar home systems based on proof of payments, and the Simpa Revenue Management System, a centralized software solution in the “cloud”, accessible via SMS gateway and over the internet, for payment processing and accounts settlement.
