売れば売るほど損失 The More You Sell, the More You Lose

自家発電電気の売電の現状と傾向(1)、売れば売るほど損失：

FIT（固定価格買取制度）開始当初（2012年度）の42円/kWhから毎年低下し、現在（2025年4-9月）は15円/kWhで、売電価格は当初の約三分の一になっています。

あたかも、政府による詐欺のようです。

太陽光発電など自家発電で発電量が消費量を上回った時に余剰電力として電力会社に売電するには電力会社との接続契約が必要で、そのための設備設置、手続きと費用も必要です。

単純に考えても売電すれば1kWあたり15円以上の赤字（買電価格約：31円/ kWh ＞ 売電価格：15円/kWh、FIT認定）です。そして、この低い売電価格は卒FIT後にはもっと下がり、8.5円〜12円/kWhとなり、赤字額はもっと大きくなるでしょう。

その対策は小型高効率自家発電による100%自家消費です。

Current Status and Trends in Selling Self-Generated Electricity (1) The More You Sell, the More You Lose:

The FIT (Feed-in Tariff) rate has decreased annually since its inception in fiscal year 2012 (42 yen/kWh), and currently (April-September 2025) stands at 15 yen/kWh, meaning the electricity selling price is now approximately one-third of its original level.

It's almost like government fraud.

When self-generated power, such as solar power, exceeds consumption, selling the surplus electricity to the utility company requires a connection contract with them. This necessitates installing equipment, completing procedures, and incurring associated costs.

Simply put, selling electricity results in a loss of over 15 yen per kWh (purchase price approx.: 31 yen/kWh > selling price: 15 yen/kWh, FIT certified). Furthermore, this low selling price will decrease even more after the FIT period ends, falling to 8.5 to 12 yen/kWh, meaning the loss amount will likely become even larger.

The solution is 100% self-consumption through small-scale, high-efficiency on-site power generation.
