Daily average, maximum, minimum and hourly temperature data were collected to evaluate the solar water pumping system for small scale irrigation systems in Nanyamba, Tanzania.

The set of minimum temperature is used together with maximum temperature to calculate the average temperature which will be used during the design of solar PV system

Solar radiation, Temperature, and Clearness Index are the set of data which were used to crosscheck the design of more than 9 systems which were installed in Dodoma. The designed year were confirmed and information were taken from the data to re-design the system and conducting economic feasibility

Temperature (Maximum and Minimum) were used to assess the voltage drop of solar panels and inverters. These information were uploaded to design product centers to come up with the system size which takes into consideration all factors.
