Target solar coverage of load
%

Share of mining + house load you want solar to cover on average.

Estimated PV size: 6.0 kWp
Estimated PV cost per kWp: 900

Mining hardware

Pick a miner model and how many you run. Daily revenue comes from your pool stats.

Miner count
units

Expected revenue per miner
per day

Current daily revenue per miner at your pool, after pool fees.

Miner power at uptime: 5.39 kW

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.

Grid electricity price
per kWh

Average price including taxes and fees.

Feed-in tariff
per kWh

What you get paid for exporting excess solar to the grid.

Power a household or site?
How do you want to enter it?
Average monthly bill
currency

What you pay the utility per month.

Derived household load: 24.0 kWh/day

Financial assumptions

Project horizon
years

Number of years you want to project.

Discount rate set to 6.0%. Change in Advanced if needed.

This is an engineering-style model, not a prediction engine. Always sanity-check inputs against your installer quotes, pool stats, and local regulations.

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

  1. Start from a sensible one-miner, grid-tied preset.
  2. Choose grid-tied, grid + battery, or off-grid mode.
  3. Adjust solar size, battery capacity, and grid price.
  4. 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.
