Wind & Solar

Wind and Solar Power - Africa's Natural Solution

Developing and third-world countries are the losers of accelerated climate change. These countries that largely rely on agriculture are severely affected by extreme weather conditions and changes in climate conditions. However, they do not have the money to adapt accordingly. And the increasing scarceness and rising prices of fossil fuel oil hamper their development. It is against this background that rural electrification with reasonable renewable energy becomes of particular importance, because decentrally generated electricity allows access to clean water, to health care services, education and economic development.

Solar Power

While many of the areas where we work receive almost 365 days of sun a year, the majority of people still live without light and electricity. 3rd World Tech is working to enable communities to harness this energy through solar power, specifically through small-scale technologies such as study lamps, solar electricity for classrooms, dorms and power for computer labs. We provide solar water pumps and water purification systems that can serve both schools and their communities.

Wind Power

These wind power offers advanced-technology products that let homeowners and businesses generate their own clean power. These turbines are also used for off-grid homes, for rural electrification, and to boost the performance of solar electric systems. They generate electric power and feed the battery source when the blades turn. There are small generators at the base of the blades that turn mechanical energy into electrical energy. Steady winds without turbulence are a must for maximum power. Electricity produced by wind generation can be used directly, as in water pumping applications, or it can be stored in batteries for household use when needed. Wind generators can be used alone, or they may be used as part of a hybrid system. Hybrid systems are especially useful for winter backup of home systems where cloudy weather and windy conditions occur simultaneously.

Solar Panels

Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect.The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.
