Projects are carefully researched to deliver maximum environmental and educational benefits. System components are based on the power needs of the school, for example, how many computers are used? do students have night study? do teachers' residences draw power?


During the coming decades it is certain that island schools will be striving for more electronic learning equipment in their classrooms and this will require more power. Think about what equipment children where you live have in their classrooms. Future proofing is achieved by: 1. Premium components are used to withstand island conditions. 2. System capacity exceeds the school’s current needs so additional electrical devices, such as computers and projectors, can be added without the need to modify the power system. 3. Systems are expandable. While the design of these systems (usually AC Coupled) means they cost a little more initially, they allow for low cost future expansion simply by adding extra solar panels or a wind turbine.

    Power is collected either from the sun by solar panels or from the wind by wind turbines. Large systems may include a combination of both these technologies. The size of the generating devices is determined by the power supply needs of the school.


    The power collected by the solar panels or turbines is either used immediately or stored in batteries for later use.  The systems will usually have two types of inverter to manage the power flow from the generators and to the school. Inverter size is determined by the appliances the system supplies and the size of the power-generating devices.

     

    Heavy-duty batteries are installed to store the power. When power is needed, the inverter transforms the battery energy into electricity that can power appliances such as lights and computers. At most sites the generator will remain available for high load periods and battery top-ups if needed.

     

     

    Most systems use high wind rated ground mounting systems.  These particular systems allow simple expansion of solar arrays by bolting on extra mounting components and adding more panels.  Ground mounting also removes the uncertainties associated with fixing to school roof structures.

     

     

    It is critical these systems are not installed and then forgotten. Ten percent of contributions are set aside for future maintenance. Should we benefit from carbon credits, this will also contribute to the long-term performance of the systems.

     

    Schools are asked to commit to learning about renewable energy and energy efficiency. The systems provide a hands-on opportunity to do this. Computers, a camera and internet access may be provided to help students share their learning experiences with overseas schools.  Some schools receive energy efficient lighting to enhance the results of the power system.  

     

    Supplying computers is not a core objective of the Foundation and donated funds are only used to supply one or two, if needed, to assist schools to communicate with overseas schools and share learning experiences. However, we are delighted to discuss sponsorship of new laptops for schools. While appreciated, donations of second-hand laptops are not accepted -- we do not have the capacity to manage this.
