これまでにご紹介した我が家の小型・太陽光自動追尾型発電（600W）・蓄電（1,000W＋600W）システム（通称；ひまわり発電所、写真）は自作可能で、公開しています。
ひまわり発電所の自作のポイントは
１．自動太陽追尾架台の製作と太陽高追尾用制御装置製作
２．主・副2電源（自家発電電源・商用電源） 自動切替スイッチの製作
ですが、すべて公開していますので、自身で確認して、コピーして下さい。
現状では、1000Wの蓄電池の電気がゼロになれば、自動的に600Wの蓄電池に切り替わり、電気を供給継続し。この畜電池もゼロになれば、電力会社からの電気に切り替わります。
日中は自家発電した電気の半分程度を家で使いながら同時に半分ほどは蓄電池に蓄えます。
太陽が沈んだ後は日中に蓄電池に蓄えられた電気を使いますので自家発電した電気は、安い価格で売電せず、100%家で消費しますので、完全な地産地消で、長距離送電ロスも生じません。

The Compact Solar Tracking Power Generation (600W) & Storage System (1,000W + 600W) (Commonly known as: Sunflower Power Station, SFPS, pictured) at my home (nicknamed the Sunflower Power Station, pictured) introduced previously is DIY-buildable and publicly available.
Key points for building the Sunflower Power Station (SFPS):
1. Construction of an automatic solar tracking mount and a control unit for tracking solar altitude
2. Building an automatic switch for the primary and secondary power sources (self-generated power and utility grid power)
However, all details are publicly available, so please verify and replicate them yourself.
Currently, when the 1000W battery's charge reaches zero, it automatically switches to the 600W battery to continue supplying power. When this battery also reaches zero, it switches to power from the utility company.
During the day, the household uses about half of the self-generated electricity while simultaneously storing the other half in the battery.
After sunset, the household uses the electricity stored in the battery during the day. Therefore, the self-generated electricity is not sold back to the grid at a low price; instead, 100% is consumed by the household. This achieves complete local production for local consumption, eliminating long-distance transmission losses.
