Questions
常见问题 · all FAQ · contact · answers updated 2026-11-01
Does it work outside Germany? · 德国以外能用吗?
Yes for the comparison itself: usable kWh, € per kWh, warranty and red flags work for any quote in any currency. The tax and registration notes are for Germany only; set 'Private home PV in Germany?' to No elsewhere and check your local rules. · 对比功能通用,任何币种都可;税务与登记说明仅适用于德国。
Why compare € per usable kWh instead of the total price? · 为什么按每可用 kWh 比较?
Quotes often show nominal capacity, which is always larger than what you can use. Dividing the cost by usable kWh puts all quotes on the same basis; Verbraucherzentrale NRW also recommends comparing price per usable kWh. The workbook adds € per kWh delivered within the warranty, which also accounts for warranty limits and efficiency. · 报价常写标称容量;按可用容量折算才可比,另加质保期内每交付 kWh 成本。
Is the 0 % VAT rule covered? · 是否说明 0% 增值税?
Yes. The guide summarises § 12 (3) UStG and the Federal Ministry of Finance FAQ: 0 % on supply and installation of PV storage for systems on or near private homes, with the 30 kW(p) presumption and the BMF's 5 kWh storage presumption. The workbook flags any quote that charges VAT. This is not tax advice. · 是,依据 § 12 (3) UStG 与联邦财政部 FAQ;报价含税会被标出。
Does it recommend a battery brand? · 推荐品牌吗?
No. There are no brand picks and no affiliate links. The example quotes are fictional and are not market prices. · 不推荐品牌,无推广链接;示例为虚构数据。
How do I get the files? · 如何拿到文件?
