Four Misunderstandings About Solar Energy

Did you know that enough solar energy hits the earth for an hour, enough to run the globe for a year?

Did you know that global solar installations have increased almost 50-fold in the last decade?

Did you know that the cost of solar power has fallen by 99% since the late 1970s?

Yes, solar power is the most abundant and is fast becoming the fastest growing and cheapest energy source in the world.

1. Is there enough solar energy?

Ever since we started cooking meat over campfires, it's been hard to get rid of the idea that energy is stored in fuel and released by burning it.

Renewable energy like solar doesn't need to be created, it needs to be harvested. Solar energy is a constantly occurring, constantly renewed force of nature. So what we need to do is capture the solar energy around us and make the most of it.

Every year, under clear skies, about 9 gigawatts of solar energy falls on every acre of earth. To put an estimate on the potential of solar energy, it is estimated to generate 1,000 watts per square metre.

This means that the amount of electricity produced by the solar photovoltaic roof is exactly what we need. For example, the modest conversion efficiency of even a modern solar panel (about 20 percent) is enough to keep our house running.

The power of solar energy is endless, please feel free to use it boldly!

2. Solar energy is too expensive?

For this concern, xiaobian just want to say to you, you worry too much! 10 years ago, solar energy was expensive! But between 2009 and 2014, the average cost of solar panels fell by about 75%. As global solar panel production continues to grow and the cost of solar power continues to fall, solar energy is becoming more and more integrated into our lives. In many parts of the world, it already competes with most other energy sources.

Some new, large solar farms supply electricity to the local grid at wholesale prices of less than 3 cents a kilowatt-hour.

Solar energy has the advantages of continuous energy, very simple maintenance, and easy mass production and installation anywhere. It can be installed on large-scale solar farms, in homes, offices, and even on our watches.

Solar will be the cheapest and least polluting energy! The world is rapidly moving towards solar power.

3. Will solar energy strike in cloudy or cold places?

Dark and cold does reduce the power generated by solar panels, but it still generates enough energy to be useful. Germany, for example, is not a sunny or warm place, but it leads the world in solar energy.

At the same time, it could be said that solar energy likes the cold. The efficiency of solar panels increases as the temperature drops. In the cold climates of the north, a large number of solar roof arrays are generated during the winter. Sunlight reflection in winter snow also increases production.

4. Solar can't be trusted?

Laugh about it, and say responsibly that solar panels are completely reliable!

Most solar panels generate electricity for at least 30 years, perhaps longer. Solar pv has been developed in foreign countries for many years, and the technology has been mature. At present, solar photovoltaic in China also ushered in the spring. The state subsidy and local subsidy show that the state has recognized it, and the state subsidy for a period of 20 years is enough to show its service life.
