Simpa Solar Home System
A pay-as-you-go solar home system available in India.
The Simpa Solar Home System is an integrated home energy system that includes an embedded keypad (Simpa Regulator) combined with the Progressive Purchase platform. The platform allows a pay as you go solution for end users. The hardware system includes a solar panel, battery for energy storage, lights, fan and device charging ports. The software system (Simpa Revenue Management System) is a centralized solution in the “cloud”, accessible via SMS gateway and over the internet, for payment processing and accounts settlement.
Simpa Networks is headquartered in Noida, Uttar Pradesh, India.
Simpa has established operations in 8 districts of Uttar Pradesh, India.
Simpa Networks employs payroll sales agents and has registered dealers who distribute the systems.
Down payment and ensuing payments are shared with the customer at the point of sale. User defined payments are made in person in exchange for a keypad code that correlates with a period of available energy use.
Customers of Simpa Networks in India sign two-year contracts. Payments are calculated on a daily basis, and customers are obliged to buy at least 25 days’ worth of service every month, though they can choose how they want to distribute their payments over time.

Simpa Networks offers systems with panel ratings ranging from 30 – 100 watts and battery sizes ranging from 17 – 26 Ah. Pay as you go functionality is enabled through retail agents and a keypad approach. Mobile payments are not yet widespread in India, as compared to parts of the African SHS market. Therefore, customers must pay a Simpa agent and receive a code until the system is paid off entirely. The code refers to a specific number of days of energy availability. ^(interview with representative, June 2016)
