Excess Energy: 4.5 kWh/day
Your array produces more than you use. Put it to work:
Store in Battery Bank
Add 4.5 kWh to your battery bank for evening/night use. The simplest, most efficient option — 90-96% round-trip with LiFePO4.
Hot Water Diversion
Heat ~113L of water by 40°C daily. Most common, saves gas/wood.
Crypto Mining
~0.23 USD/day at current difficulty. Free money from waste energy.
Local LLM / API Hosting
Run inference on ~15hrs of GPU time. Sell API access.
Gravity / Pumped Hydro
Pump water uphill, release through turbine at night. Store ~3.1 kWh.
Grid Feed-In
If hybrid system, sell back at ~$0.05-0.15/kWh = $0.45/day.
