Introduction

This project is about finding the number of solar panelsrequired to produce energy for a home that can cover 65% of the utility bill for the consumer. The project also asks general questions about how the energy is divided into two main suppliers and how the government provides incentives to the people using renewable energy. The project also highlights the uses and capabilities of a solar energy panel and how it should be installed. Along with the key details, major formulas were used to find the key power generation per hour that must be equal to 2.05kW. This builds the layout to giving us the number of solar panels which is 8. The findings also suggested the places where the panels should be placed and how the electric panels are integrated with other components.

1. Introduction

We are the contractors and are assigned a task for the installation of solar panels in a house in order to create a renewable energy source. We are given the dynamics of the situation.Firstly, the house has a garden with small trees and wildflowers where solar panel cannot be installed but it is suitable for us to install it on the rooftop. The house is a single story bungalow with a gable roof. The dimensions of the roof are given. We are given the utility bills and other required stuff so that we can reduce the utility cost. We can select solar panel of our ownchoice. Then we need to perform the cost analysis, calculating miscellaneous in the installation etc.

Figure 1 shows the front entrance to a small bungalow-style house located at 511 Erie Street in Lafayette, IN.  It is a single-level house.   There are smaller trees in the yard.   The yard is planted with wildflowers and is not suitable for a ground-mounted solar array.  The neighborhood covenants have no restrictions for roof-mounted solar photovoltaic.

 Roof for solar panels is here

Figure 1.  Carter’s House at 511 Erie Street, Lafayette

The left side of Figure 2 illustrates the roof where the solar panels will be placed. The roof has a 9 x 12 pitch, roughly 36 degrees with respect to horizontal. The roof is not directly south-facing. The azimuth of the roof is approximately 210 degrees from true north. An ideal south-facing roof would be at 180 degrees.

Figure 2 shows the average annual kW power needed in Sally Carter’s house. The x-axis shows the months of the year 2016 and the y-axis shows how much kW power is needed in each month. The red line denotes the average that makes the building a zero-energy building. A zero-energy building has an annual consumption of energy that is roughly equal to the amount of energy produced by the renewable energy source. The picture below shows that we get energy consumption and production equal to 5kW annually.

Figure 2.  Electricity use on a monthly basis

We get to see that in January, the amount of energy required in the house is the most needed energy while in June Sally requires the least amount of energy to run in the house.................
