The policy over photovoltaic power generation in Spain Spain aimed at the big increase in renewable

energy, and proclaimed the government ordinance in 2004 and 2007.

The contents of the government ordinance are buying the electricity generated by photovoltaic power generation.

Spain extracted Germany in the installation

capacity of photovoltaic

power generation, and

became the world's No.1.

The problem in photovoltaic power generation in Spain Because the electric power acquisition policy

went too far, the burden increased in finances.

It became impossible to increase new photovoltaic power generation.

Moreover, the damage

caused by weeds etc.

has occurred in the

photovoltaic power plant

using a fallow land.

Conclusion

Photovoltaic power generation is increasing slowly.

The rate of increase changes a lot by a policy.

Also technically and politically, photovoltaic power generation still needs to be improved.

We have to observe the policy of future Japan.
