Understanding a Solar Panel Warranty

There are a lot of variables to consider when installing a solar panel system. Depending on the unit, the home, the surrounding environment, and the spot on the globe, solar panels can vary greatly in their final system output. This complex mix of factors can lead one to believe that the lifespan of an average solar panel is totally unpredictable.  But, if anything, solar panels are one of the most reliable investments you can make and the length of a solar panel warranty is quite indicative of this. Regardless, individuals looking to install a solar panel system need to seriously consider the different solar panel warranties that are offered by solar installers.

Manage Your Expectations for Solar Panel Warranty

As solar panels age, they are expected to be less efficient just like your car. Common standards suggest that a 5-year old panel may see a slight decrease in efficiency and be operating at 95% of its original efficiency, which will further drop to 80% by its 25th year. These numbers can change based on all the factors mentioned earlier, and some evidence suggests the average panel lasts much longer than these standard values.

A solar panel that remains efficient is important for owners looking to recoup solar installation costs and make solar power a more affordable option than the electricity coming from your conventional utility company power grid. To protect those financial interests and ensure that they are getting a good value, consumers should seek out the best solar panel warranty.

Comparing a Solar Panel Warranty

Here’s a comparison of different companies and the warranties they offer.

SunPolar guarantees solar panels will operate at 90% output after 12 years, and 80 output at year 25.

Suntech has solar panel warranties protecting panels that operate at 95% at 5 years, 90% at 12 years, 85% at 18 years, and 80% at 25 years.

Trina Solar’s solar panel warranty varies depending on the type of solar panels. For monocrystalline installations, an 80.18% output is guaranteed at the 25 year mark, while for polycrystalline installations an 80.7% output is guaranteed 25 years into a system’s lifespan.

Yingli Green is atypical in that it offers a solar panel warranty for panels that are only one year old, guaranteeing a 98% output. At the 10 year mark they protect panels at 92%, and at the 25 year mark they protect panels at 82%. This is one of the most strict policies, guaranteeing that panels will be efficient for longer.

Homeowners should rest easy knowing that most major solar panel production companies stand by their panels for such lengthy periods of time. This allows them to get a solar panel installation with the confidence that it will be productive and cost efficient for a long time knowing they have a solar panel warranty to back their purchase up.

Looking at Solar Panel Windows

Solar panels continue to gain market share around the world as their efficiency improves and their costs go down. Typical photovoltaic solar panels are getting a little better every year, but there haven’t been any major advancements in the technology for some time.

That is until now, and the upcoming introduction of solar panel windows proves to be a new promising way to use photovoltaic technology. Recent advancements from the National Renewable Energy Laboratory have resulted in the largest-ever organic photovoltaic (OPV) segment, which can eventually be used to produce new solar technology like incredible solar panel windows.

Solar Panel Windows Look Promising

As the working size of these OPV modules continues to increase, they can be used to cover standard size windows or larger segments of people’s homes. This can be done by creating ultra-thin and invisible plastic solar cells that can then be applied to practically any surface on a home. These cells can be layered over windows, roofs, siding, or almost anything else, adding to a home’s total solar profile considerably when compared to standard solar panel units, which are physically obtrusive and visually distracting when installed on top of a house’s roof.

This major breakthrough in the solar power industry will allow individuals to install a solar panel window in their home that’s totally see-through and generates additional electricity for their home’s power system. It’s a perfect mix of green electricity production and wonderful aesthetics, something solar power has never been able to achieve before. The same window people look out to see a bright sunny day will be absorbing the sun’s rays to provide electricity.

Solar Panel Windows Remain In Development For Now

Although the technology is impressive, it is still in the early stages of development and has some major limitations to overcome before it becomes viable to consumers. The primary concern with this advanced technology is that it’s less efficient than current PV solar panel options. As the technology is further developed, these efficiency limitations will eventually be lifted and costs will be reduced, making this the primary choice for solar power in the home in the very near future.

Solar panel window technology is definitely closer than ever, and it’s a wonderful sign of things to come in the world of solar power for the average household.
