What are the benefits of solar energy in Eritrea?

The government of Eritrea has been making efforts to promote the use of alternative sources of energy, especially solar energy, to mitigate the problems associated with the use of fossil fuel. A major benefit of solar energy is that it does not pollute the environment and saves money in the long run even if its installation cost is quite high.

How do I install a solar water pumping system?

Installation of footings, posts, screws and/or in-ground fasteners shall follow manufacturer’s instructions and associated installation manuals. A number of solar water pumping systems are provided with a single post mount array frame. Others are provided with frames to be connected to one or more posts.

How many solar powered streetlights are there in Asmara?

As part of its efforts to promote the use of alternative sources of energy, the MEM built in April 2018 a photovoltaic plant east of Asmara. The plant generates an average of 11- thousand kilowatt hours of electricity per day. Moreover, in Asmara, more than 400 solar powered streetlights, covering a distance of 13 kilometers, have been installed.

Should 13000 litres (3434 gallons) be used for solar water pumping?

So, should 13m3 or 13000 litres (3434 gallons) @ irradiation of 5.4kWh/m2 be used for selecting a solar water pumping system or should 10 m3 (or 2642 gallons) @ irradiation of 4.38 kWh/m2 be used? In reality both could be used and it is possible that the same system would be selected for both. If this is the case, then the array

Where is a solar water pump located?

In these systems the solar water pump is located within the borehole or well. These pumps are generally available for 100 mm (4 inch) and 150 mm (6 inch) boreholes. The solar array is typically located near the top of the borehole/well and the water is generally pumped to a storage tank. The pump controller is typically located at the solar array.

How to choose a solar water pumping system?

The type of solar water pumping system: borehole/well (submerged), floating or surface will depend on the water source. If the source is a borehole (proposed or existing) or deep well, then a submersible pump that fits the borehole or well should be selected. If the water source is a river, then a surface pump should usually be selected.
