A deal being offered in my area is:

  • they cover the roof with insured PVs, which remain the property of the supplier for 30 years. The supplier installs and maintains them at no cost. They repair any damage. Homeowner pays absolutely nothing.
  • no batteries. Homeowner’s consumption is gratis when the sun is hitting. Any unused energy goes back to the grid.
  • homeowner gets no credit for what goes back to the grid, but they still benefit from free energy they consume when the sun is out and ultimately a reduced energy bill.
  • after 30 years, the panels and everything become the homeowner’s property. (The panels are likely worthless at that age anyway)
  • if the roof needs to be renovated in the future, the supplier removes the panels and reinstalls them at no cost, but the homeowner will have some fees for things like scaffolding.

The supplier profits from some kind of green certificates from the gov.

Seems like a no-brainer, on the edge of too good to be true. So I’m trying to decompose this to look for traps and anti-features.

It seems to boil down to homeowners trade roof space for energy in return. 30 year contract.

It complicates any plans to go off-grid. A homeowner can buy the PVs at a price that decreases every 5 years, starting at €850 each in the 1st year. So €8500 for 10 panels. Then they can exit the contract and go off-grid in the first 5 years for that price. That price is where the deal seems a bit sour. A PV should only cost around ~€60, correct? Isn’t €850 an extortionate price for a PV? If someone knows they want to go off-grid in the future, I get the impression they’re better off rejecting this deal and buying their own panels.

They install a few different meters. So I wonder if it’s really just fancy metering. E.g. wouldn’t it make sense to feed all solar power into the grid, then just pause or offset the homeowner’s meter for energy they consume from the grid while feeding the grid?
