由太陽能政策消息，開始研究家庭備電
From solar news to household backup power
我開始研究備電，唔係一開始就想買一部電源。係見到英國容許合規插電式太陽能板的消息，才想到：如果停電，太陽能又幫唔幫到屋企？
My backup-power research began with news about compliant plug-in solar in Britain. Could solar also help my household during a power cut?
政策消息，點解令我想到備災？
From policy news to preparedness
政府在2026年8月27日公布合規插電式太陽能板可供家庭使用。這個安排有產品安全要求，亦可能涉及業主、freeholder 或規劃許可；唔等於任何太陽能板都可以插入牆身插座。
On 27 August 2026 the government announced household use of compliant plug-in solar. Product standards and property permissions still matter; it does not cover arbitrary panels plugged into a socket.
慳電費，同停電時有電用，係兩個需要。Energy Saving Trust 明確指出：一般插電式太陽能板會在停電時關閉。想備電，要另看儲電及可獨立供電的配置。
Saving on bills and having power during an outage are separate needs. Energy Saving Trust says plug-in solar switches off during a power cut. Backup power requires suitable storage and independent supply capability.
先問自己需要乜
Start with household needs
我最先想到雪櫃、電話同照明。與其只比價錢，我要先想停電幾耐、邊幾件電器一定要用、部機搬唔搬得郁，以及有冇合適位置擺太陽能板。
My priorities were the fridge, phones and lighting. I considered outage duration, essential appliances, portability and a suitable place for panels before comparing prices.
最後先買電源，太陽能板再諗
A power station first; panels later
當時研究到最後，我先選了 BLUETTI Elite 100 V2，暫時唔加太陽能板。呢個係按我屋企需要作出的購買決定，唔係通用推薦，亦未有實測報告。Threads 當時的價格、回本及續航估算，都唔應當成今日的保證。
I chose a BLUETTI Elite 100 V2 first and deferred the panels. This was my household purchase decision, not a universal recommendation or a tested review. Historical prices, payback calculations and runtime estimates are not guarantees.
下一步應該係記錄實際用電同測試結果，再决定要唔要加配件。先弄清楚需要，先至知道買乜。
The next step is to record actual consumption and test results before deciding on accessories.
由「可以自己裝」，到「停電可唔可以用」
From self-installation to outage backup
之前見到插電式太陽能的政策消息，我最初想的是：原來一般家庭可以更容易接觸太陽能。跟住就自然想到備災——如果有天突然停電，有塊太陽能板是否就會安心一點？但查下去，先發現自己其實把不同的用途放埋一齊。
The policy news made solar feel more accessible. I then wondered whether panels could help during an outage, before realising I had mixed together different purposes.
插電式並網太陽能，主要是日間發電供家居使用，減少向電網取電；便攜太陽能板配電源，則要按電源規格把電充入儲電機。兩者的接駁方式、用途及限制不同，唔可以見到「solar」就當成同一套備援方案。
Grid-connected plug-in solar helps supply a home while the grid is operating. A compatible portable panel charging a power station is a different arrangement, with different connections and limitations.
因此我把問題改成：如果供電中斷，我究竟想保住甚麼？答案唔係全屋照常生活，而係雪櫃、電話、燈，同有需要時的 Wi-Fi。先縮窄到基本需要，研究就開始有方向。
I narrowed the question to what I wanted to keep working: the fridge, phones, lights and, where possible, Wi-Fi, rather than normal whole-home use.
容量、輸出同重量，係三個不同的決定
Capacity, output and portability
最初我都係睇「幾多錢」同「幾多電」。之後先明白，Wh 講儲電量，W 講輸出能力。儲得多，唔代表一定帶得動每件家電；帶得動，亦唔代表可以用很長時間。真正選購時，要連電器啟動需要、插座種類同使用時數一齊睇。
Wh describes stored energy, while W describes output power. A large battery does not necessarily run every appliance, and sufficient output does not guarantee a long runtime. Consider appliance starting requirements, connections and duration.
雪櫃又唔係一個固定瓦數、由頭到尾不停轉的負載。當時我請 AI 同事按自己雪櫃資料估算時數，當作比較的起點；正式使用，仍要記錄實際情況。開門次數、環境、其他同時使用的電器，都會令結果不同。
A fridge is not a constant load. My specification-based estimate was a comparison aid. Actual operation needs measuring, and conditions and other loads affect the result.
重量亦好現實。原帖提到11.5kg，我用「兩歲小朋友」去理解自己搬唔搬得動。這個比喻幫到我作決定，但唔代表每個人都方便搬；要諗放邊、搬幾遠、有冇樓梯，同家中邊個會使用。
The weight felt more understandable when I compared it with carrying a toddler. That was a personal way to think about portability, not a guarantee that everyone can comfortably lift it.
付款頁，令我重新記起自己的目的
The checkout brought me back to my needs
當時主機是£399，太陽能套裝到了£848。這些只係2026年10月選購時的紀錄，唔係今日售價。真正令我停下來的，係由「準備停電」慢慢變成「既然有太陽能，不如連慳電費都一齊做」。
At the time, the power station was £399 and the solar bundle £848. These are historical purchase figures. I realised I had shifted from backup preparation into trying to justify savings as well.
我曾經用假設的年發電量同電價計過回本，但假設唔等於自己屋企一定做得到。日照、擺放位置、實際有冇用到所發的電，全部都重要。不能為了令數字好看，一出太陽就叫兒子努力打機。😂
I explored a payback calculation, but assumed generation is not a household result. Sunlight, placement and whether the energy is actually used matter. I cannot tell my son to play more games just to make the figures work.
所以最後仍然係先買電源。先把主要需要處理好，等有實際使用紀錄，再決定是否值得加板。對另一個家庭，答案可以完全不同：有人只需要手機同電筒，有人要照顧特定設備，有人甚至唔需要買大型電源。
I bought the power station first and deferred panels until I had practical experience. Another household may reach a different conclusion, including needing only modest charging and lighting supplies.
買完之後，仲有新問題，但唔急住加購
New questions after buying
買完之後，我又發現產品頁的「+ Charger」原來可能係高速車充配件。原本略過的字眼，突然變成另一條研究路線：沒有市電、沒有合適日照時，是否有其他補電方式？
After buying, I noticed that a “+ Charger” option could refer to a faster vehicle-charging accessory. It raised another question: what other charging options might be available?
不過我未有實際測試車充，所以這裏先記錄問題，唔將未試過的功能寫成經驗。要再查電源輸入限制、車輛兼容、安裝及成本，先知道這個配件係咪適合自己。備災唔應變成不停加配件的購物遊戲。
I have not tested that accessory. Compatibility, installation and cost need checking before deciding whether it suits my setup. Preparedness should not become an endless accessory purchase.
接下來值得記錄的是：實際負載用電、滿電後的可用時間、搬運是否方便，以及自己是否真的需要太陽能補電。札記先留低決定的過程；有測試結果，再寫試用。
The useful next records are measured consumption, runtime, portability and whether solar charging is actually needed. This note records the decision process; testing can follow.
