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.
When homeowners are considering solar offers on the EnergySage Solar Marketplace, we often hear questions about a solar panel’s manufacturer origin and whether it’s a good idea to choose Chinese panels for an installation. This is a common question as the latest estimates indicate that China is manufacturing roughly 70% of the world’s solar panels today – a dominant market share and a clear indicator of China’s key role in the global solar industry. China has a significant impact over worldwide solar trends like pricing, warranties and manufacturing practices. For example, the 80% decline in worldwide solar prices between 2008 and 2013 occurred largely due to improvements in manufacturing costs in China. And because China is such a major player in solar, many U.S. homeowners are asking “should I choose Chinese solar panels and will it match the quality of other top brands?” In this article we’ll break down pricing, quality and brand influence of Chinese solar panels.
Installing solar panels is becoming a home improvement project that any homeowner can take on. Now that you can buy solar panels off of Amazon and eBay, you may even be considering installing a home solar energy system yourself. A popular DIY option is to purchase a solar panel kit from Renogy, a California-based company that manufactures solar panel kits for DIY solar installations. Many solar shoppers comparing their options on the EnergySage Solar Marketplace also explore their DIY solar options – but before you make a home solar purchase, we recommend you learn more about how Renogy panels compare to other brands.
When you compare your solar panel options from leading companies like SunPower, Canadian Solar, LG, Hyundai and SolarWorld, one of the biggest factors to consider is the solar panel warranties offered with their products. Solar panels come with two main warranties attached: the materials warranty, also known as the product warranty, and the production 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 insurance covers the integrity of the panel itself, and protects you against problems such as 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.

Tesla’s plans to make solar panels have been known for years. The company is constructing a factory in Buffalo, NY, specifically to produce Tesla solar panels, but until recently not much more was known about their plans.
In April 2017, the much-discussed solar panel product was finally revealed, but the company didn’t announce it with the fanfare usually reserved for Tesla product releases. Instead, the Tesla Energy website was quietly updated to include a page specifically dedicated to solar panels alongside its other energy products like the Powerwall and Tesla solar roof.
In the growing world of clean energy enthusiasts, many homeowners are looking into solar panels and trying to find the absolute cheapest way to install them. Like many other home improvement projects, solar shoppers are often seeking a do-it-yourself option. In the past few years, DIY solar has evolved from a niche concept to a common phrase heard around the solar industry, leading homeowners to wonder if buying solar panels from websites like eBay or Craigslist is a good idea. This article breaks down the pros and cons of doing a DIY solar installation through eBay and explains when it makes sense to have a professional system installed.
