Crypto Mining with Solar Calculator
Size your miner fleet, solar array, and batteries. Estimate energy flows, grid imports, payback time, and long-term profit in one place.
System mode
Choose grid-tied, grid + battery, or fully off-grid.
Location & solar
Set your average peak sun hours directly. Use the slider as the source of truth; adjust based on your site or installer guidance.
Annual-average PSH (kWh/m²/day). Example near this value: Sydney, Australia ~5.0 h/d (Subtropical coastal).
Do you already have a solar quote?
Share of mining + house load you want solar to cover on average.
Mining hardware
Pick a miner model and how many you run. Daily revenue comes from your pool stats.
Total miners running in this project.
Current daily revenue per miner at your pool, after pool fees.
Load, grid, and batteries
Start with your grid price. Add household load if you want to co-power a site. Choose a simple battery size.
Average price including taxes and fees.
What you get paid for exporting excess solar to the grid.
What you pay the utility per month.
Financial assumptions
Number of years you want to project.
Economics summary
Cash flow over time
Bars show yearly net cash; the curve shows cumulative payback.
Energy balance - typical day
Average hourly load vs solar. Battery and grid are factored into the economics, not drawn separately.

How this calculator thinks
Under the hood, the model simulates a "typical day" hour by hour: solar production, miner and household load, battery charge and discharge, grid imports/exports, and unmet load for undersized off-grid systems.
- Solar yield from system size, peak sun hours, and losses.
- Miner power from count, per-miner watts, and uptime.
- Battery behavior from capacity, depth of discharge, and efficiency.
- Yearly cash flows from mining revenue, grid costs, OPEX, and feed-in revenue.
Practical defaults, tweakable
- Start from a sensible one-miner, grid-tied preset.
- Choose grid-tied, grid + battery, or off-grid mode.
- Adjust solar size, battery capacity, and grid price.
- Plug in your daily revenue per miner and horizon.
When you want more control, flip to Advanced mode to tune degradation, OPEX, discount rates, and yearly revenue change.
Frequently asked questions
What does this calculator estimate?
It estimates the economics of running crypto miners powered by solar, with or without batteries. It models daily energy flows, grid imports/exports, and converts that into yearly cash flows, payback time, and long-term profit.
Does it use live coin prices and difficulty?
No. You provide the expected daily revenue per miner at current difficulty and price, plus an optional yearly change percentage. This keeps the model transparent and easy to adjust as markets move.
Can I simulate fully off-grid mining?
Yes. Switch the system mode to off-grid and size solar and batteries. The tool will warn you if the system is undersized and cannot cover the full daily load.
Is this financial advice?
No. This is an engineering-style calculator for back-of-the-envelope planning. Always treat results as estimates and combine them with your own research and local regulatory, tax, and installation constraints.
