Abstract - The enhancement of energy generated using
the power plant and hence reducing the total land and solar panel acquisition costs hence greatly reducing the investment required.
solar photovoltaic panels in a limited space is important in urban areas due to increased land cost in the recent years. Although there exist different procedures, technologies and methodologies to focus the sunlight on solar panels, we have suggested a new approach to enhance the energy generation from the photovoltaic panels, i.e., by keeping two solar panels facing each other to make use of the sunlight reflected off panels. Furthermore, inclusion of a self-cleaning technology for solar panel setup can promote efficiency in terms of electricity produced, reduce manual maintenance required and protect the solar cell.

2. Methodology
Due to high land cost in urban areas, the present study is significant for reducing costs when setting up a power plant or even solar panels for domestic use. We have shown an increase of over 100% in the output. The present modeling results are limited to 10-watt, 12-volt polycrystalline solar panels. Our result is more applicable to roof tops of the houses or smallscale plants. However, the justification of the installation costs associated with solar panels must be considered. Thus, one needs to have an optimal cost when designing the number of solar panels required for a certain power requirement. It should also be based on the site location.
After a lot of brainstorming sessions and consulting various research papers, we concluded that the two panels should be placed at 24° tilt towards either side to ensure maximum absorption during both halves of the day (before and after noon) in case of cloudy weather during either time and to avoid either of the panels casting a shadow over the other one as reflected in the model. A setup with a single 10-watt, 12-volt polycrystalline silicon solar panel was made with complete circuitry and readings of voltage and current at different times were taken to calculate total average output of a single solar panel with same specifications as the solar panel used in project design. A prototype model of the design was fabricated and was set up along a circuit consisting of a DC-AC converter box, energy meter and a LED bulb for providing an output to complete the circuit. The energy meter alongside a digital multimeter were used to determine and record the output of the designed model. Two solar panels identical to the solar panel used in single panel system were used for greater accuracy.
1. Problem Statement Today, the whole world uses electricity, it has become an integral part of our lives. We rely on it for many important services that maintain our way of life. The main sources of power that we utilize are coal and oil, both of which produce pollutants that are harmful to the atmosphere and the environment. By relying on non-renewable energy sources, the price of energy rises exponentially, and eventually becoming too expensive to incorporate into a power plant. Recognizing this urgent issue, we have decided to focus our study on improving the state of solar energy generation as an alternative to non-renewable resources. With improvements in technology and more sophisticated solar panels being designed each year, solar energy is slowly becoming as cost-efficient as coal and oil. However, this new field has many challenges that must be overcome before it can be established as a major source of energy. We want to assist in solving one of solar energy’s pressing issues faced while considering switching to solar power generation, the high initial investment cost and large area required for setting up a solar power plant. If the power generated per solar panel is increased this inevitably leads to a decrease in number of solar panels required to reach targeted output of

To use methods to enhance energy generation such as developing a model consisting of solar panels facing each other which make use of sunlight reflected off either of the panels. To develop a feasible solar panel model for both domestic and commercial use.
A comparative analysis of the results from both of these systems was done to determine and experimentally validate the effects of the changes in design on efficiency of solar panels.
3. Theory: Absorption and reflection of incident sunlight One of the main reasons for the low efficiency provided by solar panels is that when sunlight is incident on a panel, not all of it is absorbed by the panel due to reflections from both, the photovoltaic cells as well as the dust resistant protective
