My hypothesis is that the gable roof will be the best type of roof for solar panels. I think this is because of its shape—both sides are angled like a triangle, which allows them to collect sunlight throughout the entire day. In comparison, the butterfly roof has one slanted side that is partly blocked by the overlapping top section. Because of this, the slanted side can only collect sunlight later in the day, while the top section mainly collects sunlight around midday. For these reasons, I believe the butterfly roof would be the least effective option for solar panels.

Sunlight has tiny particles that hold its energy called photons. Inside the solar panels there are millions of  electrons and each electron is surrounded by positive and negative atoms. When the photons hit the electrons they transfer their energy and the electrons bounce around through the wires until they hit the controller. The controller controls the amount of electricity going to the battery if there is too much electricity going into the battery at once it can short circuit. After the electricity goes through the controller it will hit the inverter. The inverter makes the (DC) direct current change into (AC) alternating current. I also went and made graphs and how much the average house would need to pay to have solar panels. And also for every 10 solar panels you have and much money would you save on a electricity for every KWH.Gabel roof  The gable roof is a common roof that is used on most houses. This roof is usually combined with different types of roofs. The gable roof is shaped like a triangle and has two flat sides, the other sides angle down at a 30 to 45 degree angle. Butterfly roof  The butterfly roof is a roof that is more commonly used in modern homes,  to have a crisp angled look. The butterfly roof can be made in two ways, one has a flat top and a support underneath and then the other piece of the roof points into the support and a 30 to 45 degree angle.

Fixed variable is the amount of light to the house, light intensity and the equipment. When conducting the experiment I did it in a dark room so the only light source is the hydroponic light. I ran two experiment because of the faulty wiring. First in series and then in parallel, with the gable roof and butterfly roof.

First I laid the houses on the wood board and then wired them together. Then I started the experiment by turning on the contorer and light bulb, in a dark room. Then I followed the protractor that I made and glued to the back on my board to measure angles. The hydroponic light then got rotated from side to side and front to back, at every angle I stop and wright down the amount of voltage the solar panel were giving the battery.

Experiment #1 Gabel roof (long side to long side)      Over all the butterfly roof had more output in both experiments. 180-0 150-0 120-0 90-12.0v 60-0 30-0 0-0

Gabel roof (short side to short side) 180-0 150-0 120-12.0v 90-12.0v 60-0 30-0 0-0

Butterfly roof (long side to long side) 180-0 150-0 120-12.5v 90-12.5v 60-12.5v 30-0 0-0

Butterfly roof (short side to short side) 180-0 150-12.3v 120-12.4v 90-12.5v 60-12.4v 30-0 0-0 Experiment #2 Gabel roof ( long side to long side) 180-0 150-0 120-0 90-0 60-0 30-0 0-0 Gabel roof (short side to short side) 180-0 150-0 120-0 90-0 60-0 30-0 0-0 Butterfly roof( long side to long side) 180-0 150-0 120-6.4v 90-6.7v 60-6.5v 30-0 0-0 Butterfly roof (short side to short side) 180-0 150-3.5v 120-6.4v 90-7.1v 60-6.3v 30-0 0-0

This shows that the butterfly roof is better at collecting sunlight throughout the day, even though the gable roof was expected to perform better. The shape of the roof allows more room for light at many different angles. This explains the higher energy output.

In conclusion, my experiment showed that roof design plays an important role in how effectively solar panels collect energy. Although neither house produced a large amount of power, the butterfly roof performed more consistently, charging the battery at more angles and producing higher voltage levels than the gable roof. My hypothesis was not supported by the results. I predicted that the gable roof would be the most effective, but the butterfly roof changed the battery and more angles and more voltage. My experiment showed that the roof design plays an important role in how solar panels are effective.

The Energy sage and Aurora solar helped me understand what solar panels are, what they are made of and how they work. I also used these websites to help me get the knowledge of what is DC (direct current)and AC Alternating current). I used websites that talk about roofing to show me how the gable roof and butterfly roof look and what angles their panels go at. These websites were Avenue road roofing and Property investments. The Calgary residential solar calculator and UCA helps Alberta websites help me understand how much solar panels are and how long it takes to pay the solar panels back. It also helped me get the information to make my graphs. I used this information to make sure that my background research is accurate and trustworthy rather than my own opinion.

Overall the butterfly roof collected more sunlight. The original plan was to wire the panels in series but after conducting the experiment I realized that the gable roof had a disadvantage because of the way the series wiring works. When the panels are wired in a series both panels have to collect energy at the same time. The butterfly roof had both collected sunlight while the gable roof had a lot of trouble because of its sharp angle. To improve accuracy, the system was rewired into a parallel circuit so each panel could operate independently. During this process, additional challenges occurred with matching the correct 6-volt bulbs and batteries. Attempts to combine 1.2-volt batteries to create 6 volts were not successful, demonstrating how proper electrical components and setup are critical for reliable experimental results.

These are all the links that I used to help me understand and research about my project.

I acknowledge my dad for supporting me and helping me wire my house to the solar panels. I acknowledge my Mom for helping me understand the topic and supporting me in pushing forward. I would like to acknowledge my own efforts for being in the science fair for a second year in a row, and encoring myself to push forward and have a harder topic
