Electricity has been named by many Tanzanians as the biggest inhibitor for success.
Tanzania has the largest population in East Africa, estimated at 52,482,726, with a very high annual population growth rate of 2.77%. 31.6% of the population lives in an urban area, leaving an estimated 35,897,237 people residing in rural areas. Access to improved drinking water sources is available to 55.6% of the total population, with just about 3/4 of these people living in urban areas. 46.8% of Tanzanians have unimproved drinking water sources, the majority of which reside in rural areas. With regards to improved sanitation facilities, 15.6% of the population utilizes them, leaving 84.4% of Tanzanians with access to solely unimproved sanitation facilities.
Access to safe drinking water and the use of improved sanitation facilities are used as measurements for the development and overall well being of a country. Improved drinking water sources include piped household water collection, as well as access to protected dug wells, springs, and rainwater collection. Unimproved drinking water sources are unprotected dug wells and springs, along with bottled water and tankered truck water.
Compared to the world average of 89% of the total population having access to improved drinking water, Tanzania has fallen majorly behind. While taking into account the use of improved sanitation facilities as a means for measuring development, Tanzania also lacks due to the fact that the majority of the population is not able to ensure hygienic separation of human excretion from human contact. Finally, just over 75% of Tanzanians live without electricity, and rely on toxic kerosene or diesel generators for lighting.
Current National Grid and Electricity Access
The current national power grid in Tanzania is summarized as inefficient because of its inability to provide power to the majority of the population. Powered by fossil fuels and hydroelectric, the lines exist in the northern and eastern part of the country and sparsely in the south, but are nonexistent in the more rural west. Increased access to the national grid is at the extremely slow growth rate of 1% per year. Furthermore, in many cases people whose homes are connected to the national grid still do not receive electricity. With the expansion of the national grid, many site unreliable energy supplies and poor quality of supply as great problems. Furthermore, it is expensive to extend the national grid and distribution systems due to a lack of government funding.
Over three quarters of the population live without access to electricity, and many Tanzanians rely on charcoal for cooking and firewood collection. Currently, one of the largest threats to deforestation in Tanzania is the collection of firewood for fuel. In addition to this, the dirty smoke emitted from charcoal fires leads to many chest and lung problems. Electricity has been named by many Tanzanians as the biggest inhibitor for success. This takes into account the fact that shopkeepers have to close their doors early due to a lack of light, schools can not operate outside of daylight hours, and many medical facilities have to send patients to farther locations for certain tests and operations.
A Solution for Development
Off-grid solar panels are small and durable. They are able to manage enough power to charge cell phones, lights, and other basic necessities. The main advantage to off-grid solar panels is their flexibility, both geographically and economically. Off- grid solar panels can also be implemented into improved drinking water consumption through solar water purifiers and well systems with solar powered pumps. Solar panel cookers will also help reduce the use of nonrenewable fuel sources, therefore greatly improving Tanzanians standard of living.
The environmental advantages of implementing solar panels are enumerable. Tanzania has the unique opportunity to rapidly reduce the amount of nonrenewable energy sources, by going directly to a solar powered future. With their rapidly growing population a new market of energy consumption will emerge that could be completely fulfilled through solar panels, as opposed to largely contributing to greenhouse gas emissions. Solar is dropping in price and beginning to compete with nonrenewable forms of energy. The World Bank energy data states that it costs 20 cents per kilowatt hour for solar, compared to 25 cents for fuel.
Utilizing smaller off-grid solar panels fits the budgets of rural Tanzanians. People can put the money that would have originally been spent on fuel to finance their solar systems. Microfinance organisations are now lending to allow householders to buy solar panels. The total installation
of the average off-grid solar panel can cost up to $1,000. However, locals are able to pay smaller installments through their mobile phones in order to eventually cover the entire cost. Payments such as these average around 20c a day, or can be made into larger monthly installments.
Establishing off-grid solar panel networks also offers a plethora of employment opportunities to locals. Over the next decade it is predicted that the renewable energy sector will become one of the largest employers in Africa. The leading seller of off-grid solar panels is creating on average 40 new jobs per month. Companies such as Solar Sister are offering more opportunities to women, and developing communities through leveling gender inequality. Furthermore, off-grid systems often utilize existing means of transportation to get their product to rural areas. The local jobs created through installation and equipment distribution are greatly adding to the development of Tanzania.
As with any new program challenges will arise. The main concern for new solar panel companies is being able to secure their loan payments from customers. This can be achieved through mobile payments, which allow financiers to receive small regular pay installments. After paying the installation fee, customers are able to continue to pay for the rest of the total over time. This ensures that lenders will not lose money, because they are able to remotely lock and unlock the solar panel systems, based on the customer’s repayments. Offering the option to lease the solar panels further enhances the customer’s willingness to pay the smaller fees, while allowing lenders to have collateral. With nearly every Tanzanian having access to a cell phone, mobile payments for solar panels is an effective solution.
Sustainable operation of the solar panels is another issue that must be addressed initially. In order to have a sustainable operation it is important to establish infrastructure within the locations that the solar panels will be used. In order to cut costs, it is viable to use already
existing modes of transportation to deliver the product. Various solar panel companies have installed trackers in their products, ensuring that the panels reach their destination while traveling through third party delivery systems such as trains, city buses, and local delivery people.
Maintenance must be upheld through the education of local employees. While training local people on the installation and upkeep of the solar panels, awareness of the product would also expand. This would in turn create more jobs and boost local Tanzanian economies. Overall, when the solar panel companies work with local citizens they not only save money, but help the development of the country.
There are many new innovations with regards to anti theft lock devices for solar panels. These lock devices can be bought separately, or included in the initial solar panel purchase, and often consist of bolts or locks to secure each individual solar panel. Through the expansion of more secure solar panels, the reduction in stolen products will be significant, and the security of investments greatly improved.
The final problem is managing parts of the solar panels after they are no longer functional. The biggest issue is recycling old GEL-type, lead type, and smaller lithium type batteries. Dar es Salaam City alone produces around 3,000 tons of waste per day. With this in mind, recycling old products is important to the environmental sustainability of installing solar panels.
The Recycler, Tanzania’s main source of recycling, is able to collect and store electronic waste. Getting a local organisation such as this would be a convenient option. In addition to this, there are a few international organisations that do work on recycling unusable products of solar panels. Companies such as PV Cycle are operating on a non-profit business model worldwide. They often establish global markets, and may prove to be useful in recycling solar panel batteries in Tanzania.
Furthermore, the implementation of solar panels and their usage of batteries could open a new market in Tanzania, one focused on the recycling of solar panel products. This market could be very profitable, as well as extremely environmentally conscious, because around 90% of the material recovered from solar panels and their batteries can be recycled into useful products.
Most solar panel organisations have received funding from a variety of sources. The Rural Energy Agency of Tanzania, operating under the Ministry of Energy and Minerals, works to promote access to modern energy in rural locations throughout the country. They provide resources for grants, technical assistance, and financial assistance in the form of investments for different renewable energy projects. This agency spends approximately $400million a year on supporting various clean energy sources.
International donors also help offset the cost of development and installation of solar panels throughout Tanzania. Organisations such as the World Bank, Overseas Private Investment Corporation, USAID Development Innovation Ventures Program, and The International Finance Corporation have made major investments in this growing industry. The IFC has so far provided $7 million in order to reach over 100,000 households in Tanzania. Private international investors all around the world are beginning to see the profits in investing in solar panel technology. In 2014 more than $45 million was invested by private investment companies in the off-grid solar sector, and that number has continued to grow.
As a result of the numerous ways in which solar panels will help with the development of Tanzania, and in line with the ever growing globalization of our world, it is clear that investing and supporting off-grid solar panels is a profitable and worthy venture.
