When you think of Fiji, you first think of vacation, wonderful beaches with palms and crystal clear water with perfect spots for scuba diving. We also thought of energy: Energy that could help build a more ecological electrical power supply. The existing power supply on the three separate islands of Kadavu, Lakeda and Rotuma around the Fijian mainland had been fully based on diesel generators. Now the SMA Fuel Save Controller 2.0 is helping to integrate solar energy into the power grid. That guarantees more sustainability on these islands.
Karen Roses Ltd is a family owned business operating six flower farms in Kenya. One of its farms, situated at Eldama Ravine in the Rift Valley, is at an altitude of 2000 meters, is now equipped with a 150 kWp PV system. During the day, the energy demand of the facility is almost entirely fulfilled by the solar power generated. When the national grid is working, the PV plant operates in parallel to significantly reduce the cost of imported energy.
SMA Middle East has won the Middle East Electricity Award 2015 for the best “Solar project of the year.” The project is a PV-diesel hybrid system with almost 200 kW of solar energy. It was installed in April 2014 on the roof of the plastic factory Advanced Plastic Industries (API) in Zouk Mosbeh, Lebanon.
Solar energy combined with battery and diesel generators ensures that everyday electricity demand and the needs of industrial loads can be met in off-grid regions. The first Testing Center in the world has now been set up in Germany.We spoke with Jakob Issleib about what is being done there and why it is so important.
The Pando region in the north of Bolivia is extremely remote and sparsely populated. Since a utility grid here is out of the question, the region is supplied with power from a diesel power plant. Until December 2014, just 65 percent of the population had access to electricity. Thanks to a photovoltaic diesel hybrid power plant located in Pando’s capital, Cobija, the region is now on course to having its own sustainable energy supply by eliminating its dependency on fossil fuels and increasing its electrification rate to 80 percent. By expanding its power plant to include solar energy, the local electric utility company will save around 1.9 million liters of diesel fuel each year.
The world’s largest PV-diesel hybrid power plant with a battery storage system is currently being built in the Bolivian province of Pando. SMA has been not only selected to supply the PV inverters for this project, but also SMA’s Fuel Save Controller, which recently won the Intersolar Award in the PV category. SMA was also selected to provide four newly-developed inverters for large-scale battery storage systems using lithium-ion technology.
In addition to apes and dolphins, since June you will now find something at the Athens Zoo you would not normally expect to see there—a diesel generator combined with a PV system. This PV diesel hybrid system is a joint project whose goal is to create a virtual stand-alone grid. For the research group smartRUE at the Technical University of Athens, this stand-alone grid serves as a demo and training project while also helping the zoo to reduce expensive energy costs.
The SMA Solar Academy has recently developed a free web-based training, which provides an overview on the entire topic of Industrial Hybrid Energy Solutions. The online self-learning course takes about half an hour to complete and is open to everyone interested in learning the basics of this topic in an interactive way.
With SMA’s Fuel Save Solution for large industrial applications, PV can be easily and efficiently integrated into diesel grids. The Sunny Tripower and Sunny Central inverters convert the direct current from PV modules into alternating current and feed it into power supply systems. The SMA Fuel Save Controller manages PV feed-in and the diesel genset remains unaffected. The result: An achievement up to 60 percent of PV capacity compared to installed genset capacity.
Two colleagues from SMA Australia recently travelled to the South Pacific Island of Vava’u, Tonga to commission the SMA Fuel Save Controller for the first time in the Asia Pacific region. The country’s target is to supply 50 percent of the Kingdom’s power demand from renewable energy sources by the year 2020 and in an effort to reduce costs and offset carbon emissions, the island of Vava’u has now integrated photovoltaics into its diesel power generation system. SMA’s Tim Havron and Alexander Kaemmerer would like to share their experience with SMA’s Sunny Blog.
On this blog we have already posted numerous articles on PV diesel hybrid systems, each describing PV diesel hybrid systems and what steps must be taken to install and manage such a system. The SMA Fuel Save Solution combines diesel and photovoltaics into a hybrid system, minimizing CO2 emissions and high fuel costs.
This video explains how the system works. Enjoy it.
