みんなのおうちに太陽光というアイチューザーという会社がやってる太陽光発電の販売
岡山県下の自治体も参加してはいるが民間の事業のため自治体は宣伝用のリソースを出しているぐらい
役所のリソース*1を民間企業の事業に割くのかという疑問はあるがこの事業に参加を決めた経緯や実際どの程度のリソースを割いたのかは開示請求でもしないとわからねい
仮登録だけはしていたのでシステムの仕様と概算は決まったと連絡が来た。
申込み世帯数
Vol5.5で書いた岡山県下での目標契約数40~400と結構幅がある値を出してみたが、登録が741世帯でその1/10が契約成立でも目標には至る
システム仕様
販売施工事業者と製品の選定基準について
変換効率19%以上のパネルで、集中型パワコンとかを指定されてる中なぜかフレーム色が黒であることが要件に含まれてた
銀縁は目立つから避けられがちなんだろうか
要件の内容を見る限りコスパ重視の設定となっていて、俺みたいに変な要件を出していない
最終的には長州産業が2022年4月に発売した廉価版のJAPAN BLACKに決定された
https://content-jp.ichoosr.com/api/content/fileshare/file?route=spjp/pdf/okayama-2022/both_sp_bt/elj/proposal-product-specs
JAPAN BLACKの中でもパネルが小型で変換効率が少し劣る223wモデル
The無難な製品を選択したな
施工会社は ELJ sterra 株式会社という岡山に支社がある愛知の会社
値段
長州産業の太陽光発電パッケージと工事費、消費税込みで1kw単価は寄棟の金属屋根で約24万/kw
共同購入で安くなると宣伝してる割には安さは感じない値段だな
ちょっと高めに出しておいて見積もりの段階になったらもっと安い値段を提示してお得感を出す戦略だろうか
うちに導入を決定した約9.3kと同等の42枚の9.366kwだと約15.3万/kwとだいぶ安さを感じる
うちのシステムは色々な要望出したので約25万/kwと高い

36枚ぐらいが一番オトクとなるが普通の屋根にそれだけ載る?

枚数多めに載せられて追加料金があまりかからないならお得
パワコンの容量が一台5.5kwなので過積載考えて6kw~のシステムが導入されやすいところ、その周囲の価格帯は約20万/kwと悪くない値だといえる
でもあと1~2万ぐらいはkw単価を下げたい気分ではある
ともあれ全ては追加料金次第だ
