Due to the advancement in the research and development of solar energy and its uses, there has been an immense growth of interest in the this field. This has led to many people using solar energy science projects for showcasing the immense underlying potential that the sun has to improve our day to day lives.
Now, first of all, let us take a look at some of the simplest of appliances that you can build with the help of solar energy using tools that are available all around us and which we use in our day-to-day lives. One of the simplest things that you can build for your project would probably be a solar cooker. Solar cookers does not take a lot of tools to build and can be set up in a couple of hours at the most. Here is what you need: A box where things are actually cooked. Keep in mind that this box needs to be coated with black color on the inside and covered by a glass panel at the top. Also, you will need a pretty strong magnifying lens that can focus the sun’s intense rays on to the glass covered box in order to generate the heat required to cook the food.
Another very popular idea that many people choose for their solar energy science projects is a solar water heater. These are also pretty much as easy to build as a solar cooker and all you need for this is a glass panel that absorbs the heat from the sun. You also need a pipe that is really long and pretty thin that is also coated in black paint all over the inside and outside. The pipes are placed in a panel that is covered by the glass.
Some of the other things that can be build and make use of the sun include solar panels which generate electricity similar to the photovoltaic cells. These make use of silicon panels and unlike the two listed above, take quite a bit of time to construct. It is not something that can be built very quickly.
These are some of the simple yet very effective projects that you can consider for your science fair or competition. Make sure that you know what you are building and how to do it properly using all safety precautions necessary.
