Dear Rasul Akbarov ,

It is that the countries rich with son has high resources of fossil fuels

such as the Saudi Arabian and the other gulf countries.

The second cause that these countries do not have the know how and the factories to produce solar panels in a mass production or may be even on the laboratory level

The third cause is that the cost of PV power stations was high up to very short periods perhaps very few years. They were not affordable. But now the PV power stations may produce electricity with competitive cost to that of the conventional power stations.

- The last cause may be a political and social causes.

I contributed to answer your question by proposing a road map for transferring to PV power generation.

I would like that you follow this study in the paper at the link: Article A road map for transformation from conventional to photovolt...

Best wishes

Apart from technical reasons, maybe because of the current political systems and economic development models (market economy) ?

Thank you for your answer, very concise and informative. Probably due to dust, the average annual solar radiation is not very high ?

Thanks for the detailed answer.

Dear Abdelhalim Zekry,

Thanks for the answer and materials. I will read them later. You have correctly identified the main problems. I think there are other reasons as well.

En el caso del Perú, por falta de visión y falta de conocimiento de los políticos y del gobierno central , considerando que el sur del país se tiene uno de los mejores potenciales energéticos solares del mundo y por el lobby de las empresas privadas generadoras usando combustibles fósiles como el gas y con grandes centrales hidráulicas.

gracias por la respuesta (translation into spanish by google)

Dear Rasul Akbarov

thank your interesting question

Unfortunately, there is no government support for that.

In which country ?

There are rich "solar countries" and poor ones. The former can afford to not use PV while the latter just cannot afford the technology.

Another aspect might be that PV usage requires an adequate storage technology to bridge the nightly gap. Having electricity during the day is just not sufficient (although it would be a good idea to power A/C systems with PV as the need for air conditioning goes hand in hand with solar radiation).

Looking at the map, I cannot identify countries that would be famous for pumped-storage hydroelectricity. More the contrary: solar countries often go with some shortage of hydropower (if not a shortage of available water at all).

It is worth mentioning that solar energy in desert regions have some major challenges such as:

the dust, aerosols, humidity, sand encroachment, and so on. The efficiency of some PV cells decreases by 70% or more.

Also in desert, the wind is the most active agent, therefore, wind turbines might be the best choice but not always.
