Just like other building improvements, a solar energy system is a long-term asset, with long-term payoffs. If you have a short lease (less than 3-5 years) then solar is not for you. If you have a long-term lease and plan to stay in the building for a long time, then it will depend on the following factors: do you have roof rights in your leasing contracts and will your landlord be cooperative? For the landlord, it is worthwhile to give you permission and to get a free improvement for the building that increases the property’s value. SolarKal can help you find a solution, even if you don’t own the building.
I've heard the efficiency of the panels keeps getting better. What happens if there is a breakthrough in 5 years?
Solar will only offset 30% of my energy load. The savings seem very negligible and not worth going through the process of installing.
If the customer owns the system, a solar energy system will most likely appreciate the value of the property, and the customer generally will sell it with the building. If you are under a PPA or lease, you will have the option to either pass the contract to the new owner or buy the system.
