Grid Integration of Solar PV for Green Energy

Reliable and sustainable electricity supply is critical at all levels of health care service provision. Provision of such a service in both private and public sectors carries the burden of accumulating high electricity costs and the cost of energy consumption is surely to increase by a significant margin in the coming years. Green energy technologies require little maintenance when installed and this can be for an extensive period. These are quite robust since there is no equipment part wearing off, no fuel cost, and it is easy to increase the plant size to meet growing energy demand when needed. It provides a sustainable and reliable renewable energy investment that will result in savings returns for the user. The solution is premised on the integration of solar photovoltaic based renewable energy source installation with the main electrical supply grid of the building, thereby establishing a hybrid system that will provide secure and cheaper energy supply. The hybrid system will consist of an energy storage component and a 240V solar module PV plant installation to supply 40 kW AC power to augment the existing utility power supply and the standby diesel-powered generator. The AC inverter output power from the plant is fed to the critical load of the hospital during the day and it maintains a constant supply of hybrid renewable energy supply of PV with grid or PV with battery, when the embedded generator is no longer sufficient. This will ensure that there is security in power supply to the critical load, particularly between 6 AM and 5 PM when the system is active.
