Working Environment
Solar Office
To run a successful business, reliable electricity is a must have. Therefore, the Fosera Solar Office deploys you a standard office equipment.
Imagine you have a groundbreaking business idea that already has convinced several investors and future customers. For years, you have been working on the idea and now it is ready to be implemented. As your first step, you sign a rental contract on a small apartment in your village. The perfect office. You can already imagine how you will be sitting at the table at the big window with your two employees and looking over your village soon. You are full of ideas and zest for action and you have the feeling that you can really make a difference in your home.
But you have the bad luck and the big disadvantage that the village you have been growing up in is located in a remote region and you have no, or only a very unreliable, connection to the power grid. However, to run a successful business, reliable electricity is a must have. You have to be able to perform complex calculations and project planning on the computer. Moreover, you need digital communication options such as e-mails, messengers or telephone calls to stay in constant contact with your investors and customers and to be able to close deals successfully. Your laptops, mobile phones, printer and modem urgently need a reliable power supply. Not to mention light. Once again you are disadvantaged only because of your origin and you feel helpless. Moving away is out of the question, your whole family and friends are here. You also want to change and move something here in your home town and not somewhere abroad.
The Fosera EVO could be the optimal solution for you. The system is not only able to run laptops, it also has USB outlets to charge your phones. Moreover, Fosera lights and a standing fan ensure a pleasant working atmosphere and newest standards like printers, scanners or projectors provide a modern working environment.
According to the Global Off-Grid Lighting Association, an improved access to light and power is able to unlock previously unproductive working hours. It already allowed about 44% of the users of such systems to be more flexible with their daily activities and to spend more time at work. Moreover, half of these customers have already found out how these extra work hours can enable them to make more income: on average, an additional $25 per month.
Mobile Solar Office
The Fosera EVO system enables you to have reliable access to electricity wherever you might want to work.
Recently, you have fulfilled yourself a long-lasting dream: Working as a freelancer and being your own boss. Finally, you can arrange the days as you want and how they fit perfectly to your life. Since you work most efficiently at beautiful beaches, lonely mountains or forests, you are now free to take your laptop and your old VW bus and work wherever you want to and where you get most inspired. Here, in untouched nature, you can let your creativity run free without distraction through civilization.
However, after a short time you have to realize that in practice, everything is different from what you have imagined. Your second car battery is not able to supply your laptop and your mobile phone with electrical power for a long time. Where can you now recharge your phone and your laptops? In search for electrical energy you end up more and more often on campsites. The distraction here is enormous. Screaming children, neighbors barbequing. The untouched nature is in immediate proximity – but still far away. Frustrated, you find yourself working more and more from home instead of driving your VW bus. Your creativity and efficiency decrease enormously, and you get more and more dissatisfied.
You really need something that can supply you with reliable electricity whenever you need it. Therefore, the Fosera EVO system could be the perfect solution for you. It can give you the possibility to operate your mobile office, independent, secure and completely flexible.
As a worldwide study in 2016 proved, a mobile working environment has several benefits. Within the study, 1,835 employees were surveyed by EIU. According to this survey, 63 percent of respondents stated that mobile technologies make them more productive, while another 46 percent see this as the cause of increased creativity.
Solar Hairdresser / Barber Shop
Using the Fosera EVO system, you can equip your shop with modern devices like electric razors, driers or straightening irons.
Imagine you have been running a Barber Shop for some time in a larger village in a remote region of Kenya that is not connected to the public electricity grid. The business is tough and competition is huge. Besides you, there are three other Barber Shops in your village that all have more or less the same offer. Last month, your daughter turned seven. It’s urgent time to send her to school. You want to offer your children something, they should have a better future. But your income is not enough. For some time, you have been thinking about how you could stand out from your competitors and gain new customers.
The Fosera EVO can offer you the ideal possibilities. You could offer your customers electric shaving and hair drying with the help of Fosera EVO. Besides, you can provide good entertainment with the TV and the radio, with the standing fan a pleasant room temperature and with the Fosera fridge cooling drinks. And all this in an environmentally friendly and reliable way.
The PAYG function of the Fosera EVO means you don’t have to pay high purchase costs. You can pay off the whole system in monthly instalments. And you can spend it well because the Fosera EVO will eliminate your monthly expenses for other energy resources such as kerosene and batteries.
Solar Shop/ Kiosk
Whether cafes, small restaurants, gas stations or Internet cafes – the Fosera products allow small shops to extend their offerings.
Imagine you are about to take over your father’s village kiosk. Since your father took over the kiosk from his father 40 years ago, not much has changed in the range of products. Kerosene, disposable batteries, torches, water, chocolate bars, fruits and a few more things. You want to take the opportunity of your takeover to offer new goods and services and you start thinking what you really want to change: How often have you been annoyed when your phone’s battery ran out and you had to walk for miles to recharge it? How often have you had headaches from the kerosene and diesel vapours that are generated when operating lamps and emergency power generators. How lonely and boring are often the evenings in your cabin at the end of the village, without entertainment and without light. This is about to change now. Your kiosk should become the new village meeting place. It should be a meeting point for old and young and bring technical progress to your village.
As the following planning example shows, the Fosera EVO can be the optimal solution to offer new products and services. The Fosera fridge allows you to sell cooled drinks and perishable products. The Fosera Standing Fan creates a pleasant room temperature in your kiosk during the day. As an additional service, you can charge mobile phones, radios and other consumers that can be recharged via USB for a fee. Moreover, with the Fosera TV and recoder you can make your kiosk a village meeting point in the evening, show films and sell cool drinks. Currently, there are about 24% of solar energy customers that use these kind of solar system to support their business, with 89% seeing this reflected in increased revenues. On average business owners generate an additional $29 per month, according to the Global Off-Grid Lighting Association.
The PAYG function of the Fosera EVO means you don’t have to pay high purchase costs. You can pay off the whole system in monthly instalments. You can spend it well because the Fosera EVO eliminates your monthly expenses for other energy resources such as kerosene and batteries.
Rural Life
Solar Milk Cooling System
The Fosera milk cooling fridge enables milk farmers to stay competitive – it allows you not only to produce more quantity, it also guarantees high quality.
As milk farmer, you are very content with the amount your cows produce. Every day you milk your cows and they give you about six liters per day – more than double of the amount they produced last year. However, it is very hard for you to directly sell all this fresh milk. Somedays you find customers that buy all of your storage, but there are also other days where you come back from the market still having some liters left in your milk tubes. What could you now do with the milk you still have in storage if you don´t want it to go bad. According to The National Geographic Society and the Food and Agriculture Organization of the United Nations (FAO) about 16.4% of the diary products in Afrika have to be junked during the production, especially due to the lack of milk cooling systems.
To avoid this high amount of waste, the Fosera milk cooling fridge could be the optimal solution for you. The milk that until now could not be sold, can then be stored in the fridge and can be used another day. Moreover, you can make cheese or yoghurt out of the milk. This is why the Fosera milk cooling fridge enables you to stay competitive. It allows you to produce more quantity, to produce a variety of milk products and on top of that it also guarantees high quality. Moreover, the cooling system retains milk quality which means that it ensures premium prices and, thus, ensures fast repayment.
Solar Rural Farm
To ensure high egg production, light is needed.
Daylight is not only vital for animals like chickens, it is also essential in chicken farming since light is needed for a reliable egg production. However, since an all-day outdoor run is not always possible, it is necessary to design the henhouse according to the needs of the chickens. Sometimes the weather forces the chickens to stay in the barn, sometimes the law requires that they be kept indoors. One of the problems chicken farmers than have to face is that in egg production by poultry immensely slows down because their chickens are living with few or even with no light. That is why a lot of African farmers use kerosene lamps to illuminate their stalls. However, these lamps are often harmful or even toxic for the animals.
Alternatively, to the kerosene lamps, you could switch to LED lamps run by solar light. During the days you can charge your battery which enables you to lighten the chicken poultry during night. Since the energy can stored for long time, it can also serve for rainy or cloudy days. This will lead to higher egg production. A study of “The Lumina Project” —an initiative of the U.S. Department of Energyʼs Lawrence Berkeley National Laboratory— and “Lighting Africa”- a joint IFC and World Bank program – showed that switching from kerosene to solar-LED lighting for commercial broiler chicken production will lead to lower operating costs. Morover, the solar LED lights produce substantially more light, improved the working environment, and had no adverse effect on yields. Thanks to higher energy and optical efficiencies, the LED system provided approximately twice the illumination to the chicken production area and yet drew less than half the power.

Solar Smart School
With our Fosera products you can turn a standard school into a smart school. Not only light can be provided through our systems, but also can they offer the possibilities to install laptops, projectors or printers.
What do you all need for a proper school education? You probably need good teachers who have knowledge and experiences in their subjects. Teachers, who can handle a group of young children and who can motivate them. You need a place where you can educate them, equipment like pens and papers, chairs and tables. But none of this is really useful if you don´t have light at that place. How can you teach your pupils writing and reading when it gets dark and you barely can see anything?
Light is essential for schools, but what also becomes more and more important is electricity for laptops or projectors. In the todays working environment, it is a precondition for companies that their employees are able to work with computers. That is why pupils have to learn it as early as possible. Moreover, latest at university, electricity is needed since they have to use the internet for researches. For presentations, they need projectors, also to practice for later, professional presentations.
However, according to UNESCO, in countries like South Africa, Morocco and Namibia, still 20 percent of lower secondary schools have no access to electricity. Concerning primary schools, there are actually about 80 percent of the schools without any access to electricity. In Tanzania for instance, the amount counts for 86 percent while in Uganda it is 98 percent. This is something that has to be changed. The availability of electricity is of vital importance to improve the learning environment.
The Fosera EVO system can be used to power a whole school, from high-quality lighting to powering computers, tablets and TVs.
Solar Cinema/Dance Hall
The Fosera system can also be used for 12 V Projectors, Laptops and DVD Players which enables to run a cinema. To provide visitors with snacks, the Fosera fridge can be used to serve cooled drinks or snacks.
Imagine you are living in the centrum of your town – in the old hall where once your grandfather has lived with his family. Honestly, it is much too big for you but since you can live there for free, you won´t move. Maybe someday you will sell it and rent a smaller flat, but at the moment you really enjoy living there, directly in the centrum of the village you have been growing up. Your friends also like your place. Not only because there is enough space for the whole group but also because there is this small screen where you can watch football.
According to the World Bank Group and the Digital TV Research only 6 percent of the population in Sub-Saharan Africa has access to TV signal. Thus, there is a strong demand on entertainment and for a lot of years, your friends were coming to you every evening. By time, they also started to bring friends with them, and then the friends started to bring their friends and so on. You really like having a lot of people around you and you like caring for them: Serving drinks and providing some snacks. One day your best friend asked you a question that changed your live: Why don´t you make a business out of it?
With the Fosera EVO system you would have enough power to run a projector. In front of the hall you could sell the cards to get in the cinema and sell drinks and food. The Fosera fridge can be used to cool your snacks. Moreover, it might also be profitable to combine entertainment with education. A big part of the African population is illiterate and educational movies are a good way to reach these people.
