Reducing energy costs by solar power system
Solar power systems were installed when changing air conditioning systems of our office building.
At that time, we terminated the low pressure contract that we had signed only for the air conditioning system and changed to the volume charging contract.
After changing the contract and installing solar power, electricity charges decreased (See below).
Moreover, in December 2001, We installed 36 more panels to get the benefits of solar power systems more and more.
We focus on how lighting and heating expenses will change.
