Editor’s Note: This post comes from Tsutomu Kakegawa, a resident of Myogi-machi in Gunma-ken who has installed solar panels on his new house. Original Japanese version also included below. English translation by Justin Manger.
There are many places on the internet where you can research solar power generation for your home and get good information, but here are a few words from me, a homeowner who has had PV solar panels installed. I can say that paying nothing for lighting and heating every month definitely provides some leeway in the household budget. I also take pride in the fact that my house is contributing to the eco-movement and we’re on the forefront of actually implementing this advanced technology.
Before installing solar panels, the yearly cost for our family of four was around $2500; $1500 for electricity, $700 for gas, and $300 for kerosene. After installation, our home energy system became all electric. Electricity we did not use was bought by the electric company for 24 yen (28 cents) per kilowatt. If there was relatively good weather over the year, we could sell more and if there was bad weather, we sold less. Our energy bill for the year was reduced to around $300 (30,000 yen). Since the incentives were introduced last year, the electric company buys excess electricity from us at 48 yen per kilowatt – double the previous rate. During the months that we don’t use much electricity, we can actually make between $30 and $100.
There are national, prefectural, and city incentives for solar power in Japan which is causing wider adoption. Eco-friendly cars and electric appliances are also increasing. In order to reach Japan’s goal of a 25% reduction in 1990′s CO2 levels by 2020, citizens have to contribute however they can right away.
(The price of electricity in Mr. Kakegawa’s area is tied to demand. He uses this smart grid knowledge to save money by doing energy intensive activities such as running the dishwasher or doing the laundry later at night when demand, and therefore prices, are lower).

太陽光発電システムですが、詳しくは、インターネットで調べたほうが正しい知識が得られると思います。
導入者として言えることは、毎月の光熱費の支払いが０円であることは、生活にゆとりが出るしエコに協力していると言う
感覚もあり先進的な生活であることを誇りに思っています。
導入前は、家族４人で１年間の光熱費が２５万円（電気料 150000円 ガス 70000円 灯油 30000円)
導入直後(太陽光発電システムとオール電化生活）は、電力会社買い取り価格が１ｋｗ２４円だったので年間の光熱費は３００００円位
(天候のよい年、悪い年で多少異なる）負担があったけれど、昨年から買い取り価格が１ｋｗ４８円に上がったので現在のところ
1月３０００円～１００００円儲かっている。
また導入には、国、県、市町村からの補助制度もあり最近は普及が進んでいる。エコ家電、エコカーも増えつつある。
ＣＯ２削減２５％へ向かって、日本国民は、いち早く順応しているのではないかと思う。
インターネットで、太陽光発電導入に伴う電気の買電価格や深夜電力契約など調べられると思う。
