Largely dependent on imported fuel, many island systems must grapple with soaring electricity costs and reliability issues, in part because they are isolated and they don’t benefit from economies of scale. But more and more are seeking alternatives.


Thanda island is located in Tanzania’s Shungimbili Island Marine Reserve just off the coast of Tanzania. The luxurious island boasts various activities such as spa treatments, yoga, snorkeling, and big game fishing. Accommodation at the island includes a 5-bedroom villa and 2 Tanzanian Bandas. The island resort’s website tells us that it is a magical place of incomparable experience. The Renewable Energy technology installed by the Eco Elite Solar Distribution team, the EPC for this project, will add to this.


With the most advanced Solar MD LiFePO4 (Lithium-Iron Phosphate) technology available on the energy storage market with proprietary BMS (Battery management system and the most advanced lithium cells from CATL, charged via the power conversion systems from Sungrow, the resort’s operations can run without interruption.



Ten of Solar MD’s modular HV packs were installed offering a redundancy of 800kWh Energy Storage battery charged by two of Sungrow’s SC50HV PCS(Power Conversion System) in parallel offering a 100kW charging capability. The energy generation system is a 225kWp PV plant also managed by four of Sungrow's SG50CX string inverters.



The unique factor here is that the PV to PCS ratio is more than 2 to 1, which is managed by Solar MD Energy management system to enable the system to perform smoothly.


In low-light conditions, a diesel generator provides power to cover the loads as well as charge the battery which will generally be activated around a 30% SoC (State of charge) to be switched off again at 40% SoC offering enough power to cover the loads until the PV system can charge the battery once again.



Solar MD’s myPower24 platform gives access to remote monitoring and control of the island’s energy system. The EMS allows for control over the island’s energy requirements allowing for the opportunity to save energy where necessary but also take action on high-consumption items in reducing operational costs and enhancing power quality without compromising activities on the island.
