Did you know that enough solar energy to shine on the earth for an hour is enough for us to run around the world for a year?
Did you know that in the past decade, the global solar installation has increased almost 50 times?
Did you know that the cost of solar power has fallen by 99% since the late 1970s?
Yes, solar energy is the most abundant and rapidly becoming the fastest-growing and cheapest energy in the world.
1. Is there enough solar energy?
Since we started cooking meat by campfire, it is difficult for us to abandon the idea that energy is stored in fuel and released by burning fuel.
Renewable energy such as solar energy does not need us to create, but just harvest. Solar energy is a natural force that continues to occur and renew. So what we have to do is collect the solar energy around us and give full play to their maximum effect.
Every year, when the sky is ten thousand miles clear, about 9 million kilowatts of solar energy fall on every mu of land on the earth. If you want to give an estimate of the solar potential, it is estimated that 1000 watts can be generated per square meter.
This means that the electricity generated by the solar photovoltaic roof fully meets our needs. For example, even the moderate conversion efficiency of a modern solar panel (about 20%) is enough to keep our house running normally.
The energy of solar energy is endless. Please rest assured and use it boldly!
2. Solar energy is too expensive?
For this concern, I just want to say to you, you worry too much! Ten years ago, solar energy was really expensive! However, between 2009 and 2014, the average cost of solar panels decreased by about 75% (a lot in recent years).
With the continuous growth of global solar panel production and the continuous decline of solar power generation cost, solar energy is increasingly integrated into our lives. In many parts of the world, it has competed with most other energy sources.
The advantages of solar energy are continuous energy, very simple maintenance, easy mass production and installation anywhere. It can be installed on large-scale solar farms, homes, offices and even our watches.
Solar energy will be the cheapest and least polluting energy! The world is rapidly moving towards the road driven by solar energy.
3. Will solar energy strike in cloudy days or cold places?
Dark and cold will indeed reduce the power generated by solar panels, but it will still produce enough energy for use.
At the same time, it can also be said that solar energy likes cold. The efficiency of solar panels increases as the temperature decreases.
4. Solar energy is not trustworthy?
Solar panels are completely reliable!
Most solar panels generate electricity for at least 25 years, maybe longer. Solar photovoltaic has been developed for many years, and the technology has been mature.
