Japan is a leading manufacturer (and consumer) of solar energy. 45% of all solar photovoltaic cells are produced in Japan and a great amount of what is produced is used by Japanese consumers. In fact, Japan has the 3rd largest solar capacity in the world (behind Germany and Spain).

Since I have been here in Japan, I have noticed the widespread use of solar panels. As I look around at buildings and even residential houses, I notice solar panels everywhere! Although the cost of solar panels in Japan is expensive, just like in the United States, they are somehow much more popular. It seems it is not at all uncommon for families to have solar panels on their homes!

Solar energy was already on the rise in Japan the past few years, but following the recent nuclear energy crisis that occurred in 2011 after the earthquake and tsunami, solar panels are apparently becoming even more popular. I spoke with some Japanese people, and many say they are not especially fond of nuclear power, but due to the high consumption of energy in Japan, there is not much of a choice. Because of this as well as the high prices of oil and coal derived energy, many Japanese families appear to be turning to solar power.

The government also plays a role in solar energy. They aim to meet 10% of total primary domestic energy needs with solar photovoltaic power by 2050 and are considering a making all new houses built after 2030 to come with pre-installed solar panels. The government also offers incentives to use solar power. In 2009, a feed-in tariff was enacted that required electric companies to purchase the excess power from homes and businesses for twice the standard rate.
