Solar-powered Bitcoin mining

The park is built.Earn while the grid catches up.

If the grid connection is still years away, the park can mine Bitcoin in the meantime. Indicative revenue is €50–150k a month until connection terms arrive.

Grid connection delays in Cyprus

The solar park is ready. The grid is not.

Many Cyprus solar projects wait years for connection terms. Until then the park produces nothing and still carries cost.

Idle park

A 5 MW park waiting three years

O&M (3 years)-€135,000

Mining park

3-year mining scenario for a 5 MW park

BTC mining revenue (3 yrs)+€2,880,000
Mining equipment cost-€850,000
O&M + operations (3 yrs)-€200,000
Cyprus tax (8%)-€146,400
Equipment resale value+€300,000
Net profit+€1,983,600

Difference between idle and mining over 3 years

This is the cost of waiting. A park that mines Bitcoin can cover the solar investment before the connection arrives.

Indicative figures

Indicative Bitcoin mining revenue

Based on a Bitcoin price of about €95,000, network difficulty, and Antminer specifications. These are conservative figures. Price appreciation is not included.

5 MW solar park → mining operation

Daylight mining
~10 hrs/day
No BESS, solar hours only
Miners (S21)~1,400 units
Hashrate280 PH/s
Daily BTC~0.05 BTC
Monthly revenue~€47,000
With 2-hour BESS
~14 hrs/day
Extended operation
Miners (S21)~1,400 units
Hashrate280 PH/s
Daily BTC~0.07 BTC
Monthly revenue~€66,000
With 4-hour BESS
~18 hrs/day
Close to 24/7 operation
Miners (S21)~1,400 units
Hashrate280 PH/s
Daily BTC~0.09 BTC
Monthly revenue~€85,000

How we calculate this

Mining formula
Daily BTC = (hashrate × 86400) / (difficulty × 2³²) × block reward
Current parameters
• BTC price: €95,000
• Network difficulty: ~75T
• Block reward: 3.125 BTC

BESS options for longer mining hours

2-hour BESS

Popular

10 MWh for a 5 MW park

BESS cost~€1,400,000
Extra mining hours+4 hrs/day
Additional revenue+€19k/month
Payback period~6 years

3-hour BESS

Recommended

15 MWh for a 5 MW park

BESS cost~€2,100,000
Extra mining hours+6 hrs/day
Additional revenue+€28k/month
Payback period~6.3 years

4-hour BESS

Maximum

20 MWh for a 5 MW park

BESS cost~€2,800,000
Extra mining hours+8 hrs/day
Additional revenue+€38k/month
Payback period~6.1 years

Once the park is connected, the same BESS can be used for grid services. That adds revenue and can shorten payback.

For parks already connected

Already connected? Mine the curtailed energy

Curtailment on the Cyprus grid reached 45.8% in 2025. Parks are losing nearly half of potential revenue. That energy can be used for Bitcoin mining.

The problem

Solar parks are curtailed at peak production when the grid cannot take the power. That energy is lost: no revenue, and in most cases no compensation.

The solution

Send curtailed energy to Bitcoin miners on site. Power that would otherwise earn nothing becomes cryptocurrency, at no extra energy cost.

Mining scenarios for a 5 MW solar park

How to start

From a solar park to a mining operation in 8–12 weeks

Step 1

Site assessment

Solar output, curtailment pattern, and infrastructure

Step 2

Equipment sizing

Miner count and the power infrastructure

Step 3

Installation

Container, electrical connections, and cooling

Step 4

Operations

Remote monitoring, maintenance, and revenue

Typical implementation: 8–12 weeks from assessment to the first hash
