Solar Cloud
Do you have solar panels at home? Then somewhere, a little device is writing down what your panels produce — every few minutes, every single day. That's a treasure of information, hidden in boring spreadsheet files. Solar Cloud turns those files into clear, beautiful graphs you can check on your computer or your phone. Let me show you how it works — no technical knowledge needed.
Create your free account
It starts with a free account. Click 'Get started', type your name, your e-mail address and a password… and you're in. Your data is private — only you can see your systems.
Connect your solar system
Next, you create a system — that's simply your solar installation. Give it a name, like 'Sunny Home'. Now Solar Cloud needs your log files. Most loggers save one file per day. If your logger is on your home network, enter its address under 'SFTP server', press Save, and Solar Cloud will fetch today's file every few minutes, all by itself — even when you're not looking. Click 'Copy all earlier logs' once, and your whole history comes along. No logger on the network? No problem: just drag your files onto the page to upload them.
Tell it what the numbers mean
A log file is just a table of numbers. Solar Cloud shows every column it finds, with its latest value, so you can recognise them. Type what each one means — 'Solar' in watts, 'Battery' in percent, 'Outside temperature'. Logging in Fahrenheit, but prefer Celsius? Pick the conversion, done. Then choose which ones to show on your graph.
Read your graphs
And here's the fun part. This is a summer day: the blue mountain is your solar power, red is what your home uses. Move your mouse, and you see the exact values at any moment. Want to compare? Choose 'two days', and the day before appears right underneath — so you spot a cloudy day, or a dirty panel, at a glance. Switch to Month to see every day's total, Year for every month, and Years to see how this year compares to the last. With 'Range' you can look at any period — the last six hours, or the last seven days. Drag across the graph to zoom in… and press 'Back' to return.
Combine systems
Have more than one installation — say, the house and the pool house? Combine them into one graph, and let Solar Cloud add them up for you. Right at the top you always see the big picture: what you produced today, your total since day one, and how much CO2 you saved.
Weather built in
Ever wondered whether a bad day was the weather — or your panels? Add free weather data for your zip code: sunlight on your panels, temperature, clouds, even wildfire smoke. Put it next to your production, and a low day explains itself.
On your phone
Solar Cloud looks great on your phone, too. And if your logger ever stops sending data, you'll see a clear warning — and when it comes back, the missing days are filled in automatically.
Get started
So that's Solar Cloud: your solar panels' diary, finally easy to read. Create your free account, connect your logger, and start enjoying the view. Thanks for watching!

Weather meets production
Was it the clouds — or your panels?
Solar Cloud downloads the sunlight that reached your panels, for their exact tilt and direction, and draws it right next to what your system produced. A low day explains itself in one look.
- Irradiance on your panels (W/m²) and per day (kWh/m²)
- Temperature, cloud cover, rain, wind and humidity
- PM2.5 smoke and dust — see wildfire days at once
- Unit conversions: °F/°C, W/kW, mph/km/h and more

FAQ
Questions, answered
Which loggers and inverters does it work with?
Any logger that writes one CSV file per day, named like 2026-10-04_home.csv, with a time in the
first column and numbers in the others. You tell Solar Cloud what each column means (watts, kWh, %, °C…).
Does it cost anything?
No. Solar Cloud is free to use.
Who can see my data?
Only you. Every account has its own systems, settings and logs; passwords for your logger are stored separately and never shown again.
Can I monitor more than one installation?
Yes — as many systems as you like, and combined systems to see several of them in one graph with calculated totals.
Where does the weather data come from?
From Open-Meteo's weather and air-quality models for your location, every 15 minutes. It is model data for your area — great for explaining days and trends.
