General Information

ANSOLE organises a yearly international gathering called ANSOLE DAYS. ANSOLE DAYS are a forum of exchange among non-experts, scientists, researchers, industrial experts etc, who are all devoted to promote the use of solar energy in particular and other forms of renewable energies in general to address the acute energy problem in Africa while preserving and protecting the environment. The first ANSOLE DAYS (ANSOLE DAYS 2012) with the theme "Solar Energy for Sustainable Development" shall be held in Yaounde Cameroon from the 17th to the 19th of February 2012. The meeting will consist of fondamental teachings on various forms of solar energy, presentations (oral and poster) of scientific research results, presentations of networks in renewables energies and environmental protection, brain-storming round table discussions of African researchers to seek solar energy research areas suitable for interdisciplinary interactions among african scientists, exhibition of innovative research results and exhibition of local and international solar energy businesses. International solar businesses which are interested to participate to this yearly event should contact the ANSOLE coordinator:

Company Presentation, Exhibition and Promotion

ANSOLE DAYS is offering the possibility for companies to present themselves in form of information flyer included in the hand outs, presentation in the abstract booklet or an exhibition stand with information materials. The fees for company presentation range from 150€ to 300€ depending on the level of presentation. This is valid for companies which are not sponsors. Please contact the organizers by email for arrangements. (,


Abstract submission: 30th October 2011

Registration: 30th October 2011

Notification of abstract acceptance and type of presentation (oral or poster): 30th October 2011.

For African attendees (students and researchers), it is advisable to submit your abstract and register early enough in order to receive financial support. Early registration is also necessary for better planning of the journey to Cameroon (Visa application, early booking of airticket, vaccination) bearing in mind the less developed inter-African transportation infrastructure.

Venue and Travel Information


Cameroon is known as "Africa in miniature" due to its history, culture, landscape, flora and fauna. Cameroon, with a population of approximately 20 million inhabitants, is the only African country (and second only country in the world after Canada) where both English and French (the widely used official communication languages in Africa) are official languages, underlining once more its status as "little Africa". Cameroon has hospitable people and less explored touristic sites. It is also the ideal African destination for beer lovers and its very high beer consumption (maybe the highest in Africa) is strongly related to German colonial influence. Cameroon offers a wide variety of foods and seasonal fruits, which are more than 90% organic (bio)... Cameroon has more than 20% muslim population, so that there are enough Halal food stores and restaurants in Yaounde. It is worth taking advantage of the opportunity to visit Cameroon, a country which has so much to offer, but is less known by tourists.


Yaounde is the administrative capital of Cameroon. It is the second largest city in the country after Douala, and has approximately 1,000,000 inhabitants. The city ranges over seven hills and with two rainy seasons and two dry seasons it is less humid than Douala. February is a dry period.

The University of Yaounde I, built on the slopes of hills is the oldest institution of higher learning of the country and was the sole state university until the Higher Education Reforms in the early 1990's, which saw the creation of new state and private universities. There are presently around 20 universities in Cameroon.


You will need an entry visa which can be obtained from the nearest Cameroonian embassy/consulate. If you require an invitation or acceptance letter for your visa application, please contact both the coordinator ( and the chairman of the local organizing committee Prof. Jean-Marie Bienvenu Ndjaka ( and provide following information :

    Full name as in your passport: ...................

    Passport No: .....................................

    Passport No: .......................................

    Date of issue: .....................................

    Place of issue: ....................................

    Expiry Date: .......................................


Always have a ball pen ready with you on the plane as you will need it to fill in the entry form to be handed to the border police.


It is imperative to be vaccinated against yellow fever at least ten days before travel date. Medication against malaria is also advisable prior to travelling. Vaccination cards are controlled at the airports and borders.


Return flights from Europe and the USA to Cameroon are cheaper for a travel duration of at least one week. Spending a few warm days (before or after the conference) at the sandy Atlantic beach in Kribi (a coastal town located 2.5 hours bus drive from Yaounde) is recommended, especially during the winter period in the North Hemisphere. Please inform the organizers if you are interested in a trip to the beach or participating in the sight-seeing tour organized by the conference.

Accommodation and Transport

Hotel prices range from 20000 FCA (30€) to 60000 FCFA (90€) (3 to 4 stars hotels), while the majority are found in the lower price region. Most hotels have centralized internet systems, but very few offer internet connections in the rooms or wifi (Franco Hotel). The organizing committee will make the reservations for foreign participants. Transportation will be provided from the Nsimalen airport, Yaounde to your hotel, and foreign participants will be shuttled between the hotel and the conference venue.
