Modelling, analysis and fabrication of a portable solar PV system
Sustainable, smart, and advanced renewable energy technologies are needed to tackle global warming and electrical energy demands. The solar photovoltaic systems are one the proven renewable energy converting tool to satisfy electrical requirement for residential, commercial, and industrial applications. This system can be made more useful if it is made movable. This study focuses on the PV sizing of such a system. In this research work, some of the end user appliances are selected. The electrical load of these appliances was computed. The approach of mathematical modeling is used to size off-grid mobile PV systems. The results of this attempt showed that for 850 W appliances with a daily electrical requirement of 3,267.5 Wh, a PV array of 6 modules of 175 W is required. Considering the system voltage of 12V, a 60 A charge controller, three 150 Ah batteries and a 1,020 W capacity inverter are needed. Overall this system can produce 2,018.87 KWh annually.
This system will be able to replace standard diesel generators in urban areas and in other instances, be the main power source, mainly for rural areas. To accomplish those goals, a compact frame mechanism must be constructed to ensure the utility of this system, and it must be seamlessly integrated with its backup storage and inverter.
Load calculations.
Selection of appliances.
Designing the frame.
Finite element analysis of the system.
Fabrication of the system.
Experimental testing of the system.
Economic and environmental analysis of the system.
The biproducts of fuel consumption will be mitigated completely with the deployment of this system, after a one time investment, all power generated by this system will be practically free of cost. Noise pollution will be completely subtracted from the equation as well since the system has no moving parts, it does not produce any sound.
This system can be used for several purposes thanks to its versatility: hospitals, construction zones, small scale markets, porta cabins, irrigation systems, disaster sites where an on grid power source is destroyed.
A solar photovoltaic system rated at 1060 W, which can produce 2,020 KWh annually, which is sufficient enough to provide electricity for the average domestic household.
