In collaboration with Amazide, Mavuno, and Off Grid Electric, we initiated in 2018 an Opportunity Project to bring solar energy to primary schools in Tanzania. In 2019, we increased our commitment to this endeavor and completed the installation in 36 more primary schools. We conducted surveys in the schools six months after installation, with the results showing an increase in the quality and quantity of education. Qualitatively, the lights are being used at night by teachers to prepare lessons and tutor students, and by both primary and secondary school students to prepare for national examinations. The televisions and radios are being used as teaching tools. Early morning and night programs have been initiated. Because the schools are now considered “modern,” student attendance, punctuality, motivation, interest, and confidence are all up. Quantitatively, student performance as measured by local and regional examinations are up by an average of 15%.
