The Solar Businesses in which you have invested make solar home systems (SHS) available to African families on credit.  As African families make affordable monthly repayments to the Solar Businesses, they in term can return money to you.  We’ve designed a bond product that allows Solar Businesses to return invested capital to their investors on a 6-monthly basis.  This is known as an Amortizing loan, and while this might sound complicated, the benefit to Solar Businesses is that they never have to borrow more than they need at that moment in time.
