FAQS about Palestine pv solar energy

What is the potential for solar energy in Palestine?

There is high potential for solar energy in the Palestine, with a daily average solar radiation of 5.4 kWh/m2 which should encourage its use for mass applications like cooking, industrial and domestic heating, water pumping, rural electrification, desalination etc.

How much PV power can be produced in Palestine?

In Palestine, the average values of specific PV power production from a reference system, described in Table 2, vary between 1700 and 1765 kWh/kWp for the selected three areas. A maximum value of energy that can be produced in Gaza and in the very southern region of the West Bank is higher than 1800 kWh/kWp.

Is Palestine a good place to invest in solar energy?

Palestine has some of the highest rate of solar water heating in the region, and there are a number of solar power projects. A number of issues confront renewable energy development; a lack of national infrastructure and the limited regulatory framework of the Oslo Accords are both barriers to investment.

Can Palestinians achieve 10 percent of electricity production from renewable sources?

The Palestinian Energy Authority issued a renewable energy strategy in 2012 that aims to gradually achieve 10 percent of electricity production from renewable sources by the end of 2020. According to the strategy, this goal can be achieved if certain prerequisites are attained.

What is solar water heating in Palestine?

Palestine receives about 3,000 hours of sunshine per year and has an average solar radiation of 5.4 kWh/m.
