Bangladesh is an agricultural country where agriculture sector plays an important role in
boosting the economic growth. But during dry season, collecting adequate amount of water
becomes challenging to farmers. The use of photovoltaic as the power source for pumping
water is one of the most promising areas. Solar pumps are cost-effective and environmentfriendly. This paper deals with an optimized design for solar powered pumping system that
can fulfil the requirement of water for irrigation purposes without the use of batteries or
generators during the day. In Bangladesh, from February to April and from September to
November are the cultivation periods. Among these periods, November and February are the
most critical month due to insufficient rainfall. This work aims to the water requirement for
irrigation mainly during two mentioned cultivation periods. Here, optimum tilt angle for the
panel is calculated for which the required panel size is minimum that can supply the required
amount of water for irrigation during the cultivation period.
