I was able to get some good quotes and actually discuss the system I needed for my circumstances. I was informed on the quality of the parts used as well as the warranties provided.SunPower make very good, very expensive panels. Or at least some of the best on this planet. But if you want to buy something that is meant to go on a roof and not a space probe, then SunPower solar panels are hard to beat. Now note that I did say some of the best and not some of the cheapest.
SunPower is a US company that produces panels in the Philippines, presumably because they saw the people there badly needed a boost to their low wages. The company was founded in by Richard Swanson, who first started investigating solar cells because he was fascinated with their use in space. But I think SunPower deserves credit for trying. And while the price of solar panels have had their ups and mostly downs, his law has done fairly well.
SunPower sell panels with a 25 year warranty. That means only one panel in 37, is defective and needs to be replaced. So if you have a rooftop solar system of around 5 kilowatts with 15 panels, that means there is about one chance in 2, you will have a defective panel that needs to be returned.
And those are damn good odds. Did I say return a panel? Actually, there is absolutely no need to return it. If you have a defective panel, SunPower will send someone to come and replace it. Now that is good service. And presumably they will take the old panel away and perform an autopsy to determine why it died so young and take steps to try to ensure it never happens again. Thermal expansion is a major cause of solar panel failure. It results from temperature changes causing different materials to expand and contract at varying rates and puts strain on joins between different materials and can cause cracks to form in the thin metal wires that conduct electricity.
Once those wires break and stop the flow of current they can form a hot spot that gradually burns through the protective encapsulate that covers it, which can lead to corrosion and the failure of the entire panel.
They have done this by making the wires that collect electricity a fine patterned mesh on the back of the cell, which resembles a printed circuit board. And this arrangement is apparently great at distributing stress caused by expansion and helps keep it together. They have also greatly improved the survivability of connections between solar cells by having more of them and designing them so they suffer less stress from thermal expansion.
The panels also have a thin copper backing. Copper is a soft, ductile metal useful for avoiding damage from thermal expansion and it is also excellent for resisting corrosion. Unfortunately, copper is expensive, so perhaps they could benefit from using a different material. Looking up the periodic tableas I do at regular intervals, I see that elements with properties similar to copper are silver, gold, and something called roentgenium which decays so fast it has severe trouble lasting 25 minutes let alone 25 years.
So maybe copper is a good choice. SunPower cells have a copper plate on the bottom and a light trapping surface on the top. Q-Cells appear to be moving to a Sunpower style back contact, but they have chosen aluminium. Aluminium is much cheaper than copper — so it will be interesting to see how the final Q-Cells Q. They achieve this in several ways.
Solar panels vary in their output. No manufacturing process is so precise it can make perfectly identical panels. Not even SunPower can achieve that. That is, watts is the absolute minimum. So any variation in output will end up favoring you. Positive tolerance, where there is no downside, is not uncommon among high quality panels, but there are still many that have their tolerance as plus or minus a certain percentage.By Jay Ibric Feb 20, To figure that out we are going to review cost, degradation, warranty, efficiency, technology, and value.
Sunpower clearly takes the cake when it comes to the efficiency of the solar panel, and the hardware warranty that comes from the company. However, when it comes to realizing the most valuable solar panel, Sunpower only reigns supreme when a project requires the most efficient use of the available roof space.
If you have the available roof space for a less efficient panel, you will save thousands of dollars by going with a lower cost solar panel for your house. As a consumer, it makes you question the variance in price. They have the highest efficiency panels available in the market right now. Efficiency is the ratio of the production output to the surface area of the panel itself. Just like everything else, your solar panels will age, and as they age their production efficiency will drop.
This is called degradation. Degradation happens for a variety of factors including extreme temperatures, intense UV rays, and soiling.
Depending on the panel the annual rate of maximum degradation is different. Some yearly degradation rates include:. The most important thing to consider with degradation is that these annual rates set by solar manufacturers are a maximum rate of degradation allowed per year. If the solar panel degrades at a faster rate than the one set, they will replace the defective panel. Your monitoring system will pick up which panel is producing less — this is an indicator that the panel is degrading faster than the maximum rate allowed.
Even with normal degradation, your panels are still expected to perform up to 25 years and beyond. When you look at the numbers it is important to consider if a 0. Product warranties are important to look at as well. The product warranty covers defective materials in the manufacturing of the panel. SunPower is the leader here. They have the strongest product warranty in the industry at 25 years. If your SunPower panel stops working within 25 years, SunPower will replace it — labor included.
The next closest competitor, Panasonic, is 15 years. LG has a year product warranty. Most other brands have a year warranty. When might a SunPower system be the right choice for you? Because of their high-efficiency panels, if you have limited roof space and your chief concern is getting the highest producing kWh system, SunPower may be the way to go.
There are other high-efficiency panel brands ex. In the off chance that there is an issue, it would likely be only one panel. Ultimately, which panel you should get depends on your goals and desires for your solar system. SunPower will be the right fit if you are looking for:. Solar panels produce one thing, electricity.

In the same conditions, a high-efficiency solar panel will produce more electricity than a lower-efficiency panel of the same size. For this reason, a higher efficiency rating is generally preferable.
The temperature coefficient is an indicator of how well your solar panel can handle less-than-ideal conditions. Your solar panels will likely see more than a few hot and sunny days over the course of each year, so ideally, they will have the lowest temperature coefficient possible.
Most solar panel manufacturers offer a year materials warranty, but some higher-end solar panels come with a 12, 15, 20, or even year warranty. Hanwha Q CELLS previously offered a year warranty against any defects in their solar panels, but now offer an industry-leading 25 year-warranty on newer models.
For many homeowners, the final decision around the solar equipment you choose rests on cost. The total price you pay for a solar energy system with Hanwha Q CELLS panels will vary depending on the other equipment such as inverters and mounts used in the installation, as well as the characteristics of your roof.
