The company is in Arusha city, Tanzania. Because the local grid electricity is not stable, before buying the off grid 30kw off grid solar systems from us, they used 30kw Diesel power generation system to supply power. The disadvantage of using diesel generator is used USD60 diesel cost every day, sometimes also need the grid power supplement, and the grid electricity price is very expensive. What’s worse, the diesel generator make big nosie when running.
Until now, TANFON 30kw solar power system have run more than two years, help hime to save a monthly fee of USD2050, that means saving $26400 a year.
