Dear Juliette,   Thank you very much for your appreciation, i was busy in some emeregency activities due to Flood situation in the country.   However, you have raised the following four questions for more clarification: Do you confirm that the system put in place is still working and working with only one batterie component? Yes, all the systems are working some with two batteries (6+6 Volts) and some with only one battery (12 Volts). Both are working but the battery life of two battery systems is about 8 to 10 years and the battery life of single battery system is only 1 year.       2.   You mentionned a complaint: could you tell us exactly what was the complaint about?   We received some complaints regarding charging kits which are not working and also these kits are not available in local market.       3.   What were the criteria of the success?   The criteria of success of these systems is very clear that we have the oldest systems which were installed in 1988 (22 years before) and these are still working very well. (In running condition)       4.  Could you provide us the contact details of Mr Zaman?   Please note the full name with contact details:            Mr. Zaman Leghari          Cold Chain Technician          Provincial EPI Cell, Sindh          Near JPMC, Karachi          Mobile# +92 300 3381054 and +92 321 8918147          Email: [email=zamanlaghari@gmail.com]zamanlaghari@gmail.com[/email]    Please feel free to contact with me regarding Solar Refrigerator success stories.   Regards   Expanded Programme On Immunization _________________________________ Ghulam Taqi Asst.

In Kenya, the first solar unit was installed far back in 1987, and thereafter about 250 units were installed in all those districts which we referred to as difficult to reach with LPG (Liquified Petroleum Gas) supply for the running of the refrigerators. This was one of the reasons why we had opted for solar energy to power our cold chain. This covered whole of the Northern belt of the country and part of the Coast region where sunshine is available for almost 10 hours. Initially the units were runnng well but as the programme developed some problems started emerging in terms of efficiency and mangement. Our units were roof and ground mounted for various technical reasons. The areas where these units have been installed were very windy and dusty, which required, as a daily preventive measure, that the panels be dusted with a soft cloth, nothing abrasive, and that the water ! levels in the battery be checked.  Most of the facilities were managed by nurses, who were usually women. So climbing to the roof daily to clean the panels became a challenge and the availability of the ladder also became an issue. Most of the areas where these units were installed were nomadic areas, which meant there was livestock roaming about looking for greeners pastures. The ground mounted panels were at risk since the areas where these facilities were located were never fenced. Often the animals would come and jump over the panels and damage the panels.  Further, in these areas, the solar units were also being used illegally to tap electricity to light the staff huts and houses in the night and charge the communication radio batteries, thus depleting the stored energy and consumng the energy that had been stored for the refrigerators. Being a new invention and a soure of light in remote areas, the locals started stealing the panels and vandalizing the cables and the control charge units. Despite all these problems, the batteries, which were supplied far back in 1988, continued running even after 10-15 years where the batteries were well managed. These were the original BP Solar Battery blocks. We used three different types of solar sytems from different companies and, operationally, they behaved differently. (I think Kenya was also among the first countries to use solar energy for the sterilization of needles and syringes. This didn't do very well and we had to stop it after three years.) Due to all these problems, we had to start going back to gas operations for all the solar units.  Another challenge is the skills needed for health workers to manage the solar units, especially the daily and the monthly preventive maintenance tasks. Also, when you supply energy where the health workers require cold water, want to listen to their radios, charge their mobile phones and where there is no other source of power supply, they will be forced to use what is available at the expense of the vaccine storage. Use of solar power is a good alternative cold chain strategy if well planned and managed, though capital-wise it is too expensive, but again the recurrent cost is minimal as compared with the use of LPG gas. NB. This my personal experience as the national Cold Chain and Logistics officer for over 25 years in Kenya and may not necessarily represent the current EPI officers' view.

Dear All,   I am the Store Officer in EPI Pakistan and dealing with Vaccines and Cold Chain Equipments in the country. Regarding Solar Refrigerators in our country:   EPI Pakistan has installed 7 (BP) Solar Refrigerators in 1988 in Sindh Province and these were installed by Mr. Zaman our cold chain technician in the province. After that many other were also installed and till now in this province around 50 Solar Refrigerators are installed and working very well. In this whole period we have changed only batteries of these refrigerators and we have received only one complaint regarding charging kit. These are minor complaints, we can say the result is very good.   The 50 Solar Refrigerators were also installed by our Sub-Engineer Mr. Altaf in earthquake affected areas of the country in 2005. We have installed two kind of Solar Refrigerator some from Brightlite and some from Dulas. All are working very well from last five years no complaint were received from any where.   I want to mention one thing more regarding backup timing:   The battery in Dulas is only one and that is 150 amp. Brightlite three and each is 100 amp. (Back up time almost double then Dulas)   We have changed only batteries and some complaints received regarding charging kit.   with best regards,   Ghulam Taqi EPI-Pakistan Expanded Programme On Immunization _________________________________ Ghulam Taqi Store Officer Federal EPI Cell, Ministry of Health, Islamabad, Pakistan Ph: (92 51) 9255584 Exchange: (92 51) 9255110-14 (Ext. 3146) Facsmile: (92 51) 9255086 Cell: (92) 300 5084001, 333 5084001 E-Mail: [email=ghulamtaqi@gmail.com]ghulamtaqi@gmail.com[/email]

We have about 500 Sun Frost refrigerators that were installed in Nigeria by KXN in 2008. You could contact Anthony O. Ighodaro at KXN to obtain details on their operation[email=anthony_ighodaro@yahoo.com]anthony_ighodaro@yahoo.com[/email]. We have only received positive feed back on this project.

Dear Srs. I´ve already see that You are looking for solar refrigerator succes stories, and I think that I have one. I´m mexican medical doctor that since 16 years ago working in vaccination and in that time, either in develop a system for keep safety the vaccines (2 to 8° C) in case that lost the energy, and now, I have 3 kind of frigidares, the first one that work with both energies, solar and electrical, the second one (I just win the science, technology and innovation price 2009 of the Council of science and technology of the Jalisco State in México for a system that keep the vaccines safety (2 to 8° C) for at least 35 hours without any energy in case that fail the energy, and 3, a frigidare with forced air, that keep (2 to 8° C) safety the vaccines (can be other things) for at last 30 hours without any energy. I hope this can be important for keep life with best work in vaccination in the world Dr. Francisco José Eguiarte Anaya ##text##
