What to Know About a Solar Panel Warranty

What is a solar panel warranty?

A solar panel has two warranties: a performance and equipment guarantee. A solar panel’s performance warranty will typically guarantee 90% production at 10 years and 80% at 25 years. An equipment warranty will typically guarantee 10-12 years without failing. SunPower offers the best warranties.

A solar panel’s product warranty covers the integrity of the panel itself, and protects you against failures due to manufacturing defects, environmental issues, premature wear and tear, etc. As with most warranties, a longer period is generally more advantageous to you, if you own your solar panel system. When evaluating a solar panel warranty and its manufacturer, the two most important factors on which you should focus are:

1. Product (or materials) warranty, and
2. The performance warranty
We’ll address both of these in this article as we break down our process for finding the best solar warranties offered by manufacturers.

What are the Most Efficient Solar Panels on the Market?

For those looking for the most efficient solar panels for their PV system, the first thing you need to know is how to compare efficiency metrics for different manufacturer brands. Simply put, efficiency (expressed as a percentage) quantifies a solar panel’s ability to convert sunlight into electricity. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings, the more efficient panel will produce more electricity than the less efficient panel.

As the race for the most efficient solar panel continues, it’s important to understand how more efficient panels could mean much bigger solar savings for the everyday consumer.

In practical terms, for two solar panels of the same physical size, if one has a 21% efficiency rating and the other has a 14% efficiency rating, the 21% efficient panel will produce 50% more kilowatt hours (kWh) of electricity under the same conditions as the 14% efficient panel. Thus, maximizing energy use and bill savings is heavily reliant on top tier solar panel energy efficiency.

What is the power output of a solar panel?

power output of a solar panel

Power output or wattage is an important factor to consider when comparing solar panel options. You may hear your solar installer say, “it’s a 255 Watt panel” or “the panel I am recommending is a 300 wattage.” Or, when you are reading a quote from a solar installer, you might see numbers like 245W, 300W, or 345W next to the name of the panel. They are all referring to a solar panel’s wattage, capacity and power output. So, what is the typical output of solar panels?

This piece will explain how solar panel ratings work so you can better compare your solar options. All solar panels are rated by the amount of DC (direct current) power they produce under standard test conditions. Solar panel power output is expressed in units of watts (W), and represents the panel’s theoretical power production under ideal sunlight and temperature conditions. Most solar panels on the market today have power output ratings ranging from 200 to 350 watts, with higher power ratings generally viewed as being more favorable than lower power ratings. Pricing in solar is typically measured in dollars per watt ($/w), and the wattage of your solar panels plays a significant part in the overall cost of your solar system.

What Questions Should You Ask Your Solar Company?

If you’re shopping around for a solar energy system, you undoubtedly have questions that you want to ask your solar company. But what questions are the most important ones to ask an installer?

The decision-making process is a bit easier if you divide the questions into two ‘stages’: First, you can ask the key questions which allow you to understand the value that their product offers. This will help you to rule out the options which are definitely not for you. After you’ve answered these questions, you can ask the questions that will help you make the final choice between this narrowed-down range of options. We discuss some of these questions below.
