How long will it take for a solar energy system to pay for itself?
A solar energy system will usually pay for itself with energy savings (and with any available installation rebates or tax credits) within the first half of its estimated lifespan. The actual length of time will depend on the type and size of the system. Generally speaking, a commercial system will pay for itself in less time than a residential system, and solar thermal (hot water) will pay for itself in less time than a photovoltaic (solar electricity) system.
A solar energy thermal system will usually pay for itself with energy savings (and with any available installation rebates or tax credits) within the first quarter to half of its estimated lifespan. The actual length of time will depend on the type and size of the system. Generally speaking, a commercial system will pay for itself in less time than a residential system, and solar thermal (hot water) will pay for itself in less time than a photovoltaic (solar electricity) system. And a full solar thermal system, heating the water and the space, will pay for itself faster than just thermal hot water. Previous customers have shown us before and after data which points to a pay-off ranging from 8 to 18 years. Many factors go into calculating this figure, and we would need to look at your specific home, energy bills, and a specific system. We cannot guarantee a pay-back timeframe but will guarantee it’s better than a PV system. Also, solar systems increase the resale value of your home. The
