Project Title

Implementation of Energy Efficient Dual-Facial, Dual-Axis Solar Model for Urban-Rural Electrification

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

The year wise Pakistan increases its dependency on fossil fuels. This fossil fuels have a chronic effect on the environment and dangerous for human lives. So the only occasional mercy on the environment and human life is the usage of alternative resources. These alternative resources are freely available but we are unable to make a shift. Pakistan will grow economically and environmentally if the country follows the transition step. The high price of the energy is creating a core necessity to prompts the quick cost-effective alternatives. The existing energy system encourages the distribution corporations to resort the load shedding issue. Whereas the government should choose to upgrade the alternative energy resources.

In this research, we want designed a system the bi-facial photovoltaic with dual axis tracking system, which mirrors the bi–facial model with an effect on economical price and higher efficiency for the advance nations. The project has been designed by combining the two equal watts solar penal having anti–parallel alignment with each other. The rear penal of the design system is supported by concentrator for strengthening the efficiency of the scattered irradiation. The scattered irradiation generates extra energy due to the design structure of the proposed system. With this prospect we are increasing the energy gain upto 60% of PV panels, by these arrangements the project space is compacted. The voltage of the system is conjoint increases slightly as the timely increasing irradiation strength. The power of the designed system increases with the increasing voltage proportional relationship with the current. The design system verifies the voltage, current and power measurement from all location of the calculation. Most of the panel is using single access tracking system but we are motivated to design the economical efficient and high power efficient bi–facial solar tracking system having two axes sides for the power extraction sides x1 and x2. So, this type of advance model will gain a lot of attention in the future and economical sector. So, the performance of this bi-facial solar directional system originates from the strength and angle of each location. The proposed bifacial modules produce solar power from both sides front and rear side. The bi–facial with the tracking system has been made an effort to track the motion of the sun for collecting maximum energy.

Project Objectives

The main Aims and Objective of this project are the following:

• To design a low cost and high efficiency bi-facial solar tracking system.
• To implement a dual-axis dual-facial solar tracking system.
• To analyses the output power characteristics for maximum power generation.

Project Implementation Method

Figure1: Proposed Design system

LDR:

Light dependent resistors, LDRs, or photoresistors are electronic components that are used to detect light & change the operation of a circuit dependent upon the light levels. So it will detect the sun rayses for the movement purpose.

ADC:

An Analog to Digital Converter (ADC) is a feature that converts an analog voltage on a pin to a digital number. By converting from the analog world to the digital world, by using this converter we will be converting AC signals into DC signals.

RASPBERRY PI MICROCONTROLLER:

The raspberry pi is a single computer board with credit card size, that can be used for many tasks that our computer does, in our project we are using raspberry pi as a microcontroller to help move the LDR in order to follow the sun rayses.  

RELAY:

A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations. Here those relays are connected to our solar plates.

Benefits of the Project

Pakistan have the tremendous potential of solar, power to generate vast energy with the due method. The proposed project may facilitate in reducing the pressure on the national gas grid for the supplier of gas to the domestic consumers in rural areas.To boot the solar potential within the country will effectively be used to perform the processes in textile and agro-industries. Solar energy keep on within the solid form to fulfil the demand supply gap in pakistan. 

The problem with  recent mono facial and bi-facial systems are not providing enough efficiency of gain, and they are economically high in rates, as well as space consuming systems. Those systems were not able to follow the sun rays at every axis to get full energy. So we will solve these problems in our dual-facial solar tracking system project. so we want designed bi-facial photovoltaic with dual axis tracker solar system is more efficient than all other old methods of getting solar power sources. The proposed bifacial system is high in yield and useful for all the off–grid and on–grid areas. The design system is a low–cost solar system that is adaptable and reliable to use domestically as well as commercially to get great throughput. By some implementation we are getting direct AC 220 V from 12 V. In comparison with the other systems the designed bi-facial solar system is highly efficient and economically reliable in terms of the electrical energy output.

Technical Details of Final Deliverable

The advance bi–facial system is designated for the tracking strategy which enables high collectible energy surplus at medium tracking accuracy which is new and low–cost tracking system with the soft ridge concentrator together. The bi–facial PV panels can double photovoltaic energy harvest in comparison with fixed panels and substantially reduce the price of PV energy which is fundamental aspects of the energy production. The system is designed by combining the two equal watts solar penal having anti–parallel alignment with each other. The rear penal of the design system is supported by concentrator for strengthening the efficiency of the scattered irradiation. The scattered irradiation generates a lot of extra energy due to the design structure of the proposed system. The rear penal of the system primarily increases the efficiency of the module. The voltage of the system is conjoint increases slightly as the timely increasing irradiation strength. The design system illustrates the little bit different in the observed values of front and rear penal of the voltage, current, and power.
