  2. Introduction • Solar power is obtained by collecting sunlight and converting it into electricity. This is done by installing solar panels in an open area exposed to direct sunlight, such as on the roofs buildings. Solar panels are large flat panels made up of many individual solar cells. It is often used in remote locations, although it is becoming more popular in urban areas as well.

  3. Advantages of solar power - Solar energy is obtained from the sun which requires no cost at all.- The production of solar energy does not produce any form of pollution.-Advanced technology has made solar energy systems extremely cost effective.- Does not need maintenance often, thus saving money for repair.

  4. Advantages of solar power • Takes a long time before going out of use • -Can be designed for particular needs. • - Creates job opportunities for people, such as the process of manufacturing, installing, monitoring and maintaining solar panels.

  5. Disadvantages of solar energy - Cannot be produced during night time, causing a loss of a large quantity of energy that can be produced throughout the night.- Solar inefficiency, meaning that only a small quantity of the Sun’s energy (22%). This means that a relatively vast amount of surface area is required to produce a lot of electricity, which requires large amount of space.- Costly to produce solar panels. Capital cost of installing a home solar system is high.

  6. Morocco Case study: • In the early 1990s, the Moroccan government aimed to provide its citizens both in urban and rural areas with electricity. • The national grid is centralised in the urban areas, making it difficult and expensive to connect rural households to the electrical system. • In June 2002, Morocco’s state-run operator in its electricity supply sector entered into a partnership with a private company to electrify rural households by using solar energy to produce electricity. WHY?

  7. Case study: Morocco The government provides an equipment subsidy that allows the private company to offer electrical services at affordable rates, by offsetting the high installation and maintenance costs associated with solar energy systems. HOW?

  8. Case study: MOROCCO • This technology benefitted the rural population as they do not need to move to large cites to be connected to the grid. • Using solar power to provide rural homes with electricity is a more viable option for Moroccans. The primary objective of the solar project is to provide photovoltaic kits to over 58,000 households in rural Morocco to enable them to meet their basic energy needs. Benefits
