Off-Grid Systems
juwi Solar develops, engineers and constructs off-grid projects - worldwide. These systems are energy supply solutions that are not connected to the public grid and provide the basic power supply for buildings in rural areas; producing environmentally friendly power for lights, refrigerators and communication devices. We work with local businesses to establish and operate the solar power plants and thus strengthen the local economy.
Affordable Energy for Rural Areas
juwi Solar is convinced that solar energy is one of the best solutions to assist sunbelt countries in their economic development. With our energy solutions, we provide a basic power supply for buildings, schools, small businesses or health centers. Off-grid power systems represent an attractive economic alternative to conventional generators, as they have very low operational costs.
juwi Solar plans and builds off-grid solar power systems throughout the world. With our advanced sizing software and our experience we are able to offer the optimal solution for your energy requirements. In cooperation with our local partners we can deliver worldwide and suppport the installation and commissioning on-site.
Our services include:
Solar Power Systems
Solar power systems provide the basic power supply for buildings in rural areas, allowing to use eco-friendly power for lights, refrigerators and communications devices – even when people are far away from the power grid.
Hybrid Systems
By combining different energy sources (e.g. solar energy, small wind turbines or diesel generators) it is possible to increase system availabilty and/ or lower investment costs and increase system availability. Such a combination of energy sources is particularly beneficial for larger consumers such as local commercial centers, hotels, schools and hospitals.
A hybrid system is capable to operate autonomously and juwi can retrofit existing diesel generator sites with solar modules in order to achieve less fuel consumption. These systems can be monitored locally and remotely.
Back-Up Systems
Back-up systems can be used to provide an uninterrupted power supply (UPS) from unstable public grids. When combined with solar power systems, they serve as a suitable alternative for diesel generators.
Village Electricfication
Solar based village electrification systems often represents the economically best solution for settlements in sparsely populated areas in the sunbelt countries. A central solar based power plant supplies the village with a single - or three phase minigrid.
Juwi Solar is specialised on village electrification with minigrids. Minigrids are the optimal technical solution for settlements with typical village center. A central one-or three-phase power plant empowers a small low or medium voltage grid were every household is connected to. This technical approach is also suitable for larger industrial applications.
Our village electrification systems can be realized within a power range from 2 to 300 kW. Individual adoptions can be made in order to meet power demands up to 1 MW.
Energy Containers
Containerized power solutions have many advantages, amongst them are quick deployment, standardization of equipment and cost savings in terms of in-situ construction. Due to its modularity, the energy containers could be combined to increase system capacity, and could be replicated across a region to ensure a harmonized deployment that would simplify maintenance. Our energy containers use primarily solar energy and can be equipped with other energy sources.
Small Wind and Hydro Power
A combination of solar with wind turbines and/or micro
hydro turbines represent an optimal solution, resulting in either lower
investment costs or the increase in energy available to the system.
The energy output of wind or hydro power generators is very dependent
on local site conditions. Having experiences in all renewable
energy sources, juwi can support you in the design and implementation
of the most economical and energetically optimum system for
your energy needs.
Solar Pumping
Energy and water supply often belong together in Africa and other sunbelt countries. Solar pumps for village water supply, water purification or desalination plants represent an important base for the development of rural communities. As solar pumps are not dependent on batteries these pumping systems work very efficiently and are extremely robust.
