A solar photovoltaic system provides active energy to charge the battery of 24 Volt via dc to dc boost converter (step-up converter) and battery energy is used to run the dc pump of water filter in remote areas. A boost converter increases the input voltage level of solar panel upto 25 Volt fix to run the dc motor of solar pump and at same time it charges the batteries in sun light. The boost converter switch is pulsed at maximum output power of solar. It is extracted using maximum power point tracking (MPPT) system. An Arduino Nano microcontroller is used to extract the pulse of dc to dc boost converter at MPPT of solar photovoltaic system. Keywords- Arduino Nano, dc to dc converter, dc motor pump, potable water, Solar PV system. 1. Introduction Nature and water for people: United Nations Educational, Scientific and Cultural Organization (UNESCO) ecohydrology approach for a new water culture at the United Nations General Assembly. The United Nations Educational, Scientific and Cultural Organization (UNESCO) was born on 16 November 1945, headquarter at Paris. Nature balanced the eco system and ensure the world population have sufficient portable (drinking) water while population face cries of portable water. As stated in (Nature and water for people, 2020), according to UNESCO data, one person out of three persons are living without portable water. Kingdom of Saudi Arabia (KSA) is one of the countries where 100 percent water is distilled. Numbers of companies are available to sell water while KSA government supplies filter water to domestic purpose. In
