Introduction to Solar Energy

Solar energy is all about using sunlight’s power, which is vast and constantly available. Solar panels change sunlight into electric and heat energy. This energy is key for both businesses and homes. It’s important to know how solar energy works to understand its big changes.

What is Solar Energy?

Solar energy comes from the sun’s radiation. It can create electricity, heat, and fuel chemical reactions3. People have used the sun’s power for many years, even back in the 7th century B.C. This type of power does not make harmful greenhouse gases, and it’s friendly to our planet4. The Earth gets a huge amount of solar energy every day. This shows just how much energy we can use from the sun3.

How Does Solar Energy Work?

Solar energy works through photovoltaic technology. Photovoltaic (PV) cells are usually made from silicon or other special materials. They take in sunlight to create an electric current4. Scientists found out about this in 1839. The first PV cell made from silicon was in 1954 at Bell Labs4. Basically, solar panels have many PV cells. They work together to turn sunlight into electricity.

One thing to note is that some solar panels make electricity while others make heat4. Solar panels can last over 25 years. This shows they don’t harm the environment much and are very strong45. With PV technology in many sunny places, we can make a lot of electricity even when it’s cloudy. But the amount can change depending on the sun’s strength4.

Solar energy is used from small home systems to huge solar fields. These fields have many solar panels joined together. They’re used to make a lot of energy4. It’s interesting to note that it only takes about eight minutes for solar energy to reach us from the sun. This shows how fast and effective solar energy is5.

Solar panels play a big part in green energy. But making them isn’t totally green. These panels, especially the Monocrystalline ones, create a lot of emissions. However, polycrystalline panels are cleaner even though they need electricity to be produced28.

Greenhouse Gas Emissions

Thin-film solar panels are greener to make but use toxic materials. They still involve making greenhouse gases. Comparing to coal and gas, solar panels are much better for the planet. Yet, their making process has a big carbon impact. China makes the most solar panels, with the U.S. and Europe close behind28.

solar panel lifecycle

Disposal and Recycling

What happens to solar panels after they’re done is important, too. Right now, we’re not so good at recycling them. This leads to more electronic waste and might cause a material shortage later on28. In some U.S. states, there are rules to push for solar panels recycling. These rules show how important it is to manage waste from green tech well29. Even with these efforts, recycling solar panels is not easy. The U.S. needs more effective ways to recycle safely29.

Recycling is not just about reducing waste. It’s also about getting back materials for new panels. As we work towards a greener future with more solar energy, recycling will be key. SEIA wants 30% of the U.S.’s power to come from the sun by 2030. To reach this goal, we need strong recycling programs2829. Companies must also focus on making solar panels in cleaner ways. And think about how to best handle them when they’re no longer useful. This way, solar energy can stay good for the earth in the future.
