How Long Does A Solar System Last?

Freeing yourself from fossil fuel dependence is more than a green energy project for your property. Creating your own power not only reduces your utility bills, but it reframes your relationship with the power utility company too.how long will a solar system last?

First things first; what’s the life expectancy of a solar system in order to calculate your return on investment? This question brings to light the factors that influence the lifespan of a solar energy system.

How vulnerable are the panels to damage?

Solar panels require little to no maintenance. While the conductive plates inside the panels are delicate, designers specify rigid outer layers. Whether they are tempered glass or other rigid manufactured materials, the outer layers are very durable, strong enough to withstand wind, hail, and tree branches.

How reliable are solar panels?

Solar energy arrays are reliable and low-maintenance because manufacturers test their designs rigorously. When you work on such a large scale as the best solar energy contractors, your reputation must stand the test of time. The system has no moving parts, which reduces the chances of malfunction.

Why do panels have limitations? 

According to a study, on average, photovoltaic panel efficiency drops by half a percent annually.

While built to last, the electro-ready components rely on a sub-atomic ion transfer to occur between the two charged plates. Any factors effecting the electrostatic properties of these surfaces will inhibit the panel and thereby the whole system’s production.

Humidity will inevitably permeate in over the years and affect the cells’ performance.

Coating deterioration affects the reflective coating in place to reflect as much light as possible onto the receptor plate. Like paint, heat and the Sun’s UV rays degrade the coating and reduce its effectiveness.

Shunt resistance is a side effect of using a grounded electrical current. It is required for safety but some signal loss occurs between the system and the grounding.

So, how long will my solar system last? 

The guaranteed lifespan of a contemporary solar energy panel is different for each individual model. Most manufacturers guarantee the output of their panels at an average of 25years, however they don’t just stop working at the end of the guarantee period, they will continue some level of degradation, but the manufacturer will not guarantee how much after 25 years. The time to replace panels is not when they stop working altogether, but rather, consider your solar energy array viable for as long as the financial benefits are good. When production has petered out to the point where you lose money by not upgrading, then the system is considered outdated. This exact figure is different for every property.

So, the real question to ask is not, “How long will it last?” but rather, “For how long will my solar system be economically viable?” Most solar panel owners report they paid off their solar energy investment within a few years, so you cannot lose unless you fail to take any steps to go solar. Compared to painting, paving, and updating wall art, replacing your photovoltaic panels is a relatively painless expenditure. After three decades of good service, you may be sad to see them go; that is, until fresh panels are once again put in place to reinvigorate your solar energy production.

Your month-to-month rewards may fluctuate as your solar system panels naturally degrade but over its lifetime, your investment will earn its keep in free electricity and other benefits.
