There are four main advantages about Solar
photovoltaic. Universal: The sun shines on the earth, there is no geographical
limit whether the land or the sea, whether the mountains or islands,
everywhere, can be directly developed and used, easy to collect, and do not
need mining and transport. No harm: the development and utilization of solar
energy will not pollute the environment, it is one of the cleanest energy, in
the environmental pollution is becoming more and more serious today, this is
extremely valuable. Huge: The amount of solar radiation reaching the earth's
surface each year is equivalent to about 1.3 trillion tons of coal, the largest
amount of energy that can be exploited in the world today. Long term: Based on
estimates of the rate at which the sun produces nuclear energy, hydrogen stores
are large enough to last tens of billions of years, and the earth's life span
is estimated to be several billion years.
