Pros and Cons of Solar Energy

pronsandconssolarenergyWe always talk about the different portable solar power solutions in this web site but there might be some people who still don’t know a thing about solar energy aside from the fact that it comes from the sun. Let’s take a look at the pros and cons of solar energy.

Pros of solar energy

Let’s us start with the pros of solar energy. Solar power is considered one of the greenest forms of energy around. Solar panels don’t emit pollutants. Its carbon footprint is mainly from the manufacturing of the panels, transportation, and installation.

Solar power is generated in a silent manner unlike energy from fossil fuel and other sustainable energy source, such as wind turbines. You will not notice your solar power installation working at all.

One of the advantages of solar energy is that you can harness the power of the sun to generate electricity even when you’re miles away from the power grid. It is even used in space to power satellites. Installation of solar panels is more cost effective than laying high voltage wires.

New solar energy technologies make solar panels more efficient even during cloudy days. It could be mounted on any roof, which eliminates the problem of looking for an area to install the solar panels. The initial investment for a solar power installation might be high but it will pay for itself in the long run.

Cons of solar energy

Solar energy is not perfect. It still has some kinks that need to be improved on. One of the major disadvantages of solar panels is already mentioned above, which is its high initial cost. The price of a solar power installation can give a big dent to your family’s finances.

Solar energy needs the sun to generate electricity. Even though solar panels can harness the power of sun in cloudy days, it can’t do so during nighttime. That means half of the day the solar panels are idle. Speaking of cloudy days, the weather can affect the effectiveness of solar cells. Not every solar cell can generate power when the sun is covered by clouds.

Pollution levels can also affect the efficiency of solar cells. The solar power installation might not be producing pollution but it can be affected by its surroundings. This is one of the reasons why businesses and industries are taking their time to embrace solar power, especially when they’re located in highly populated cities.

    There aren’t enough articles going over the cons of solar energy, like you just did! Good job, and I do agree with your point. There are drawbacks to this energy source that call for a back-up plan. Usually wind energy + solar is a good combo!
