Bitcoin mining is often criticized for its high energy consumption. Bitcoin mining with solar energy offers an environmentally friendly alternative. By combining photovoltaic systems with efficient mining hardware, miners can not only reduce their electricity costs but also contribute to the energy transition.
In the Miners.de Shop you will find Bitcoin Mining Hardware for Photovoltaics
☀️ Why Bitcoin mining with solar panels?
Integrating solar energy into the mining process offers several advantages:
- Cost efficiency: Self-generated solar power reduces dependence on expensive grid power.
- Sustainability: The use of renewable energy sources minimizes the ecological footprint.
- Independence: Independent energy supply protects against electricity price fluctuations and grid bottlenecks.
Projects like the collaboration between Blockstream and Block (formerly Square) show that solar-powered Bitcoin mining is not only possible, but also economically viable.
⚙️ The right hardware
For efficient Bitcoin mining with solar power, selecting the right hardware is crucial. ASIC miners (Application-Specific Integrated Circuits) are specifically designed for mining and offer high hash rates with comparatively low energy consumption.
One example is Bitmain's Antminer S19 Pro, which offers a hashrate of 110 TH/s with a power consumption of 3250 W. Such devices are ideal for use with photovoltaic systems because they can efficiently utilize the available solar energy.
Important criteria when selecting hardware:
Energy efficiency: Devices with a low energy consumption to hashrate ratio (Joules per TH) get the maximum out of solar power.
Reliability: Durable and low-maintenance devices are especially important when operated in off-grid solar setups.
Compatibility: The devices should be easy to integrate into existing solar systems and battery storage.
Recommended ASIC miners:
-
Antminer S19k Pro : 120 TH/s at approx. 2760 W – very efficient with constant performance.
-
Whatsminer M50S Plus : Also high hashrate with very good energy efficiency.
-
Antminer T21 : Latest generation with optimized performance and lower power consumption.

Integration of photovoltaic systems into mining
Combining ASIC miners with photovoltaic systems requires careful planning:
- Sizing the PV system: The size of the solar system should be tailored to the energy requirements of the mining hardware.
- Storage systems: Battery storage systems are useful in order to be able to mine even in low sunlight or at night.
- Grid connection: A connection to the public power grid can serve as a backup and allows the feeding of excess energy.
Feasibility & Challenges of Bitcoin Mining with Solar
Although the concept of Bitcoin mining with solar panels sounds appealing, its implementation is technically and economically challenging. Unlike less energy-intensive crypto mining with solar power (coins like Ethereum Classic or Kadena), Bitcoin mining with photovoltaics is particularly challenging – for one simple reason: the usually greater energy requirements.
Energy requirements of Bitcoin miners
A modern Bitcoin miner like the Antminer S19 XP Hydro requires approximately 5345 watts in continuous operation. To sustainably cover this consumption, the following requirements are necessary:
- Powerful photovoltaic system : Depending on the location and hours of sunshine, it often takes 15–20 kWp (kilowatt peak) or more to operate a miner continuously during the day.
- Generous power storage : Since mining runs around the clock, lithium-ion batteries or other high-performance batteries are required to ensure operation even at night or in bad weather.
- Grid connection as backup : In many cases, it makes sense to maintain a connection to the power grid to guarantee security of supply.
Comparison to other crypto mining projects
While some cryptocurrencies can be easily mined with smaller solar setups (e.g., via Raspberry Pi or FPGA-based miners), Bitcoin mining with a PV system places significantly higher demands – both on the technology and the budget.
Is Bitcoin mining with photovoltaics worth the effort?
Yes – under certain conditions. Who:
- has suitable areas for solar panels (e.g. roof areas, fields),
- access to funding for renewable energies,
- and buy the appropriate mining hardware ,
can mine Bitcoin in a long-term, self-sufficient, environmentally friendly and profitable manner .
Conclusion: The future of Bitcoin mining with solar
Solar-powered Bitcoin mining represents a promising solution for reducing the environmental impact of mining while simultaneously increasing profitability. By using photovoltaic systems combined with efficient hardware, miners can operate sustainably and independently.
