Lease vs. buy
Model comparison of own investment versus lease over the term.
Model calculation – not tax or investment advice
This calculator provides a non-binding, simplified model calculation based on your inputs and documented assumptions. The results do not constitute tax, legal or investment advice and do not replace an individual review by your tax adviser. No warranty is given for accuracy or returns.
In three steps you compare the lease model with buying your solar system outright.
- 01
Define the system
Enter system size, electricity price, and self-consumption share as a shared basis.
- 02
Add the models
Enter the investment cost for the purchase plus the lease fee and term for leasing.
- 03
Read the comparison
The calculator contrasts both models and shows the break-even point.
The calculator compares leasing and outright purchase of a solar system over the chosen term.
In the lease model you invest €0 and buy your solar power at a reduced price – around −20 % versus grid supply as a reference value. In return, an annual lease fee applies and the system remains owned by the lessor.
When buying outright you bear the investment cost yourself but benefit from up to −50 % power cost through self-consumption and fully own the system. The calculator contrasts the cumulative cost of both paths over the term.
From this comparison a break-even emerges, from which the higher upfront cost of the purchase can pay off against the ongoing lease.
The comparison is a non-binding model calculation using reference values.
Lease or buy – you get both models including delivery and operation from a single source.
