Simpa

Simpa offers solar power systems to households and shops in rural areas. Customers make a small initial payment to have a solar PV system installed, then it's simply pay-as-you-go for the electricity. They mimic the compelling pricing model of pre-paid cell phones. But these small payments for electricity also add up towards the total purchase price and once fully paid, the customer owns the system and enjoys the benefits of clean, reliable electricity, for free. The company was founded in 2010 and is based in Karnataka, India.
