A 20kW photovoltaic system connected to three ASIC miners, showing solar panels in bright sunlight and mining equipment running efficiently.

A homeowner's ambition to install a 20kW solar photovoltaic (PV) system for crypto mining has ignited heated discussions among enthusiasts. Critics challenge the feasibility and true costs of mining powered by solar energy, raising serious doubts about the initial claims.

Context of the Discussion

The homeowner's claim suggests their PV system could handle 120 kW of daily usage, potentially running three Antminer S19K units for 11 hours without incurring electricity costs. One commenter countered this, stating, "You ain't gonna make it with 20KWH of storage on cloudy days, you won't run for 11 hours consistently."

The Cost of Going Solar

Financial implications have also come under scrutiny. While the homeowner predicted a drop in their monthly electricity bill from 350 euros to 290 euros, skepticism looms. One critic remarked, "So you think the free power for 11hrs a day is going to make all this back? YOU'RE DREAMING." This emphasizes the split opinion on the economic viability of such a setup.

Cautionary Tales from the Community

Warnings about potential pitfalls came loud and clear. A moderator cautioned against the hidden costs often associated with perceived "free energy": "Mining with 'free electricity' isn’t always as good as it sounds. Be mindful of hidden costs, landlord agreements, and potential legal issues." This echoes a growing concern about regulatory scrutiny related to solar-powered mining operations.

New Insights Gathered

Recent comments revealed deeper insights:

  • Inconsistent Outputs: "My 22kw system was only producing 130 kwh on a clear sunny day," highlighted the variability in solar energy production. Others echoed similar sentiments, noting the challenges in maintaining consistent power supply.

  • Lack of Longevity Predictions: Many expressed doubts about the sustainability of the system, with one commenter stating, "Your math is wrong. The system won’t last 30 years." This reinforces hesitations about investing in solar mining setups.

  • Realistic Energy Use: Users shared personal experiences, with one saying, "I have 30 kwp solar and 33kwh storage and run Avalon Q sometimes I don’t even have enough power to run 24/7." This supports the notion that long-term operations might not be as effortless as proposed.

β€œAgreed. He ain’t gonna make 200kwh a day,” one user contended, consolidating doubts about the homeowner's calculations.

Key Takeaways

  • πŸ“‰ 75 cents per day per miner estimated as potential yield.

  • ⚠️ Many users advise careful consideration of the financial viability of solar setups.

  • πŸ“ "Mining with free electricity shouldn’t be taken lightly" - Top comment, urging caution.

While optimism surrounds renewable energy for crypto mining, many remain cautious about the practical and financial challenges involved. What does the future hold for the intersection of solar energy and cryptocurrency? Only time will tell.
