1 Abstract— Dead sea photovoltaic plant constructed in Palestine (2014) with power capacity of 708 KW on 10000 m 2 land . This paper propose a new design to expand the station up to 1 MW using the same land with hybrid storage system . The methodology used is decreasing the tilt angle to increase the overall capacity of the station from 1200 MWH/year to 1801 MWH/year . The results supported by PVsyst simulation package .

INTRODUCTION Palestinian energy sector has a big challenges which arises due to rapid increase in electrical demand , limited in traditional energy sources due to unstable conditions and high cost of fuel used to generate electricity . Recently , implementation of renewable energy resources such as photovoltaic systems ( PVs ) used as a solution to reduce the prices and utilities dependency on suppliers . There is significant potential for the use of the photovoltaic solar energy in countries like Palestine which receive abundant amounts of solar radiation around the year. The radiation in the surface of the sun 3.838*10 23 , 1400w/m 2 at the boundary of atmosphere and 1000w/m 2 as global standard test condition (STC) . Table.1 illustrate the practical radiation potential in Palestine and Fig.1 shows the daily sun path around the year using PVsyst.

There are many researches concerning photovoltaic systems executed in Palestine by individuals and utilities and the main projects summarized as follows : 1. Dead sea project : in Jericho , established in 2014 as on land and project , with power capacity of 708 KW . 2. JICA project : in Jericho , established in 2012 as on land and project , with power capacity of 300 KW . 3. Coca cola Co. : in Ramallah , established in 2016 as a roof top project , with power capacity of 300 KW . 4. AL_ ahli hospital : in Hebron , established in 2015 as a roof top project , with power capacity of 200 KW . 5. Hebron University : in Hebron , established in 2016 as a roof top and on land project , with power capacity of 230 KW . 6. MLR Co. : in Bethlehem , established in 2016 as a roof top and on land project , with power capacity of 200 KW . This paper discuss modification of implemented Dead sea PV project in Jericho ( -300 below the sea , latitude is 31.86 and longitude is 35.46 ) that executed by JDECO in 2014 , with power rating of 708 KW , constructed on 10000m 2 land and consists of 2360 panel and 13 inverters . The goal of this modification is to increase the capacity of this station up to 1 MW on the available limited area and convert it into hybrid station .
