Can I power a home mining rig with solar panels?

Yes, at small scale this is increasingly common and one of the cleanest ways to mine. A modest rooftop solar array (5-8 kW) typically produces more than enough during daylight to run a 400-900W mining rig directly, with surplus going to the house or back to the grid. The economics work best with net metering or a battery, because most mining benefit comes from running 24/7. Pure off-grid solar mining is feasible only with batteries large enough to cover overnight, and the battery cost usually outweighs the modest MLRT earnings. The most practical pattern for home miners is grid-tied solar that offsets daytime mining hours, with the grid covering nights.
