Monetize your watts
Your roof is a power plant. Treat it like one.
Eight ways to turn surplus kWh into income. Each watt is sold once — self-use first, then the next-best buyer takes what's left.

Solar → inverter → buyer → € back
How it works
Step 1
Generate
Your solar array produces kWh during the day. Self-consumption takes priority — what you use at home is the most valuable kWh.
Step 2
Route surplus
What you don't use is routed by the inverter / energy manager to the next-best paying channel: battery arbitrage, mining, V2H, thermal, feed-in, etc.
Step 3
Earn € back
Each channel returns € to the household. Stacking 3 – 5 channels typically delivers 4–6× the income of feed-in-only.
