Photovoltaic panels ( pv panels) have been the subject of many news and discussions in recent years, especially when faced with the energy crisis in Europe. However, many aspects and capabilities of this source of energy have remained unknown.
Palmore inteational as a well known photovoltaic panel supplier and manufacturer in Oman has reviewed 9 awesome facts on solar that may be surprising for you.
1- Solar energy is the most abundant source of energy on earth
The solar energy that reaches the earth every hour is enough to meet the energy needs of everyone on the planet for the entire year .
If we could control even one hour of solar energy reaching the Earth each year, we could keep every ounce of oil, every piece of coal, and every cubic foot of natural gas in the ground.
For example, if the Mojave Desert is covered with photovoltaic panels, it will produce more than twice the electricity that the United States uses annually.
2- The price of solar panels has decreased by 99% since 1977!
A simple solar cell cost about $77 per watt in 1977. According to the Solar Energy Industries Association and GTM Research’s Solar Market Report published in the third quarter of 2017, the cost of a solar cell is now 21 cents per watt. The whole assembled module costs 39 cents per watt.
3- Solar energy is cheaper than fossil fuels!
According to an analysis by Lazard, unsubsidized solar costs 4.3 cents per kilowatt-hour, which is cheaper than almost any option for new fossil-fuel power plants. The cheapest fossil fuel option is natural gas, which costs between 4.2 and 7.8 cents per kilowatt hour.
Depending on the location, solar energy is cheaper than coal, diesel, nuclear, and in most cases, natural gas, especially in the South American countries. If the cost reduction patte is taken into account, it won’t be long before solar power overtakes any form of fossil fuel.
4- Solar power plants can last 40 years or more!
When a solar plant is built, it is usually backed by a power purchase agreement from a customer that lasts 20 to 25 years, but that doesn’t mean the plant will be worthless two decades from now.
Not only do photovoltaic panels last 40 or 50 years, but the infrastructure of a solar power plant is very valuable. Photovoltaic panels may be replaced by newer, more efficient modules at a lower cost. In this way, they improve their performance, but once this base is established and the infrastructure is built, the solar power plant has a very long life.
5- China is the biggest leader in solar energy
Solar energy is starting to get a lot of attention in the US, but it’s still very small compared to China. GTM Research estimated in 2017 that the US would install 12.4 gigawatts of new solar energy systems. China installed 24.4 GW of solar power capacity in the first half of this year alone, and will probably exceed 50 GW for the entire year.
