What is the payback period for a renewable energy system?
A6. The payback period for a renewable energy system is highly dependent on several factors. If you wish to install solar power in a house that is already connected to the grid then the system would have a payback of between 10 years or more, depending on the system. If you are looking to offset the cost of bringing hydro to a rural home then the payback can be instantaneous due to the huge fees charged by the utility company to bring power to your house.
