World photovoltaics compared to needs and resources
Solar is mistakenly perceived by some as an area-intensive power generation technology, requiring much more space than conventional fossil fuel power plants.
Typically, developed countries such as the US, Australia and Singapore consume about 10 MWh of electricity per person per year. This figure is expected to double

Quel est le futur de la technologie N ?
Début 2018, de nombreux fabricants annonçaient des plans d'expansion de l'hétérojonction (HJT), ce qui développait la technologie N. Les décisions chinoises du 31 mai ont arrêté les plans d'expansion. Ensuite, le prix des produits P a chuté en liaison avec la réduction des coûts et les progrès de l'efficacité, alors que le marché des cellules de type N a continué d'enregistrer des coûts et des prix de vente élevés.

Profitability of a power plant in Spain built without subsidies
The terms and conditions of the 175 MW Don Rodrigo solar power plant near Seville (Spain) have been presented by its developer, the German company BayWa r.e. The project is due to be completed in 2012, with construction due to be completed in the second quarter of 2019, and has just been sold. It is being built without subsidies, which allows the developer to be independent of any political developments in a very sunny region. Above all, it is an opportunity to
