The classic mistake: requiring full amortization before sale
If you plan to resell between 3 and 7 years, solar energy should not be judged solely as an investment that is fully amortized before sale. It is necessary to think about use during the period of occupation, the attractiveness of the property and the readability of the project for the next buyer.
The 4 scenarios to compare
You resell quickly without major additional work
In this case, a project that is too heavy or too complex may be difficult to justify. We must remain very attentive to the budget and the simplicity of the message for the market.
You still have a few years with high consumption
If the property remains occupied with terminal, PAC or high bill, a significant part of the value of the project is already in use before resale.
You are selling as part of an overall improvement of the property
When solar energy is part of a broader logic of energy quality, healthy roofing and technical clarity, it can reinforce the attractiveness of the whole.
You hesitate between minimal project and ambitious project
Over a period of 3 to 7 years, a simple, clean and well-documented project is often more defensible than a very sophisticated configuration that is difficult to explain to the next buyer.
