Before deciding to install solar cells, let’s analyze the electricity usage data of our own home first. The example used in this article is the author’s own home.
The electricity usage rate has bounced back to 2840😱 compared to last month, which was recorded at 1837 units, bouncing back more than 1000 units. This isn’t even April yet!!!
Before installing solar panels, I check “my home electricity usage behavior first” because to choose the right size of the system, we need to know our actual numbers, not just guess. So I used to look back at the electricity bills for the past 7 months and recorded the units used like this…
🇬🇧 🔎 “Electricity Usage Analysis: 7-Month Review Before Going Solar”
Before investing in solar panels, I asked myself… How much electricity do I actually use? When is the peak season? What system would really be worth it?
So, I checked my electricity bills from the past 7 months and here’s what I found:
📊 Electricity Usage (Sep 2024 – Mar 2025):
Sep: 1,493 kWh (~49.8 units/day)
Oct: 2,056 kWh (~68.5 units/day)
Nov: 2,061 kWh (~68.7 units/day)
Dec: 2,326 kWh (~77.5 units/day)
Jan: 2,182 kWh (~72.7 units/day)
Feb: 1,837 kWh (~61.2 units/day)
Mar: 2,840 kWh (~94.7 units/day) ← Highest usage!
✅ Key Insights:
Usage clearly increased from December to March (likely due to heat & full house usage)
March was the peak — almost 100 units/day
Average usage = 50–95 units/day
Best suited for a Hybrid Solar System with Battery Backup
My electricity use is not stable — and it spikes hard in hot months. If solar can cut that peak, I could save tens of thousands of baht each month!
🇬🇧 After reviewing my actual electricity usage over the past 7 months, I’m confident that Going solar is no longer just a “nice-to-have” — it’s a smart, necessary step for long-term savings.
My home’s daily energy consumption continues to rise, especially during the hot season. In March, my electricity bill nearly hit 15,000 THB. With a properly sized system — such as 15 kW with 10–20 kWh battery storage — I could reduce my bills by 10,000–13,000 THB per month, while also gaining energy backup when the grid goes down.
Installing solar isn’t just a tech upgrade — it’s future-proofing your home and your finances.
Now you’ve seen how much power I use — but in the next post… I’ll walk you through how I chose my solar provider, what I compared, and why I finally made my decision.
📌 Stay tuned! I’ll be revealing the real specs I chose and my experience before signing the contract 💬
