GET INVOLVED

How to Celebrate Solar Appreciation Day

Take a solar tour

Check out your local college or university to see if they offer solar tours. Most universities have some form of solar technology that you can visit and learn about. Take a guided tour and learn more about solar energy.

VISIT

Visit a solar farm

Check with your local utility company to see if they have any solar farms in your area. Solar farms are large fields of solar panels that generate electricity for the grid. Take a trip to the solar farm and learn more about solar energy.

MAKE

Make a solar oven

Making a solar oven is easier than you might think. All you need is a cardboard box, aluminum foil, and some black paint. Cut the box into the shape of an oven, cover the inside with foil, and paint the outside black. Put the oven in direct sunlight and you have your own homemade solar oven!

BUILD

Build a DIY Solar Panel

Building your own DIY Solar Panel is not as hard as it seems. With some basic tools and basic skills, you can build a simple panel that will generate electricity from the sun's rays. You'll be surprised at how easy it is to build your own.

ATTEND

Attend a Solar Lecture

Check for local events related to solar energy. Many universities offer free lectures on solar energy and its applications. Attend one of these lectures and learn more about how you can benefit from solar energy.

WHY THIS DAY MATTERS

Why Solar Appreciation Day is Important

Solar energy helps create jobs

The growth of the solar industry has created thousands of new jobs in the past decade. With more access to solar technology, communities can benefit from improved employment opportunities and an increased local economy.

Solar energy is renewable

Solar energy is a renewable, clean source of energy that is available to us every single day. Unlike fossil fuels, solar power does not emit carbon dioxide into the atmosphere and it does not deplete natural resources. Solar energy is also free after the initial installation costs

Solar energy helps reduce air pollution

By replacing traditional sources of power with solar energy, we can drastically reduce the amount of harmful pollutants being emitted into the air. This will help improve air quality while reducing the overall costs associated with healthcare and environmental damage caused by air pollution.
