Best Solar Panels to Buy

Jinko Solar

Jinko Solar is one of the industry’s leading manufacturers of solar panels and by looking at their latest releases, it’s easy to see that the Eagle PERC 60 is their top product.  It uses the monocrystalline Passivate Emitter Rear Contact (PERC) solar cell technology to crank out 300W of output, which is more than enough for residential applications.

When it comes to solar panel technology, monocrystalline and polycrystalline are the two industry leaders. The monocrystalline technology used in this solar panel is more efficient than its poly counterpart. However, it’s also more expensive.

As such, the Eagle PERC 60 is an excellent option if you are looking for a high-end solar panel, and don’t mind spending the extra bucks. It features a corrosion-resistant construction, a feature that will come in handy if you live in a coastal town (where salt corrosion is a major problem).

Trina Solar

Trina Solar manufactures the DuoMax Twin bifacial glass solar panel, which is considered to be 22.5% more efficient.

Bifacial glass simply means that the bottom of the panel is made of transparent glass, rather than a black or white back sheet. Such a construction allows light from the sun to reflect into the solar panel easily, improving energy efficiency.

Astronergy 250W

The Astronergy 325W Solar Panel is one of the best solar panels in terms of value for money. Made by China-based Astronergy, this solar panel has one of those that have the lowest cost per watt.

The 325W translates a 16.8% efficiency, so you are getting a deal of a lifetime. That is not to mention the company’s outstanding warranty policy. Astronergy’s warranty program offers third-party insurance, meaning that if they ever go out of business, you will still be eligible for a warranty claim from a third party insurer.

That said, Astronergy is one of China’s biggest electronics manufacturers, and it’s likely that they will be in business for decades to come. Nevertheless, it’s nice to have the peace of mind provided by third party insurance.

Astronergy 325 is by no means the best solar panel in terms of construction, but the low price and the extra assurance make it a worthwhile purchase for those looking for absolute value for money.

LG is one of the world’s leading manufacturers of electronics, and it’s no surprise that one of their solar panels features in this top ten picks for 2018.

The LG 360w Solar Panel is best known for being space-efficient, packing more wattage in a 60-cell panel than many 72-cell solar panels in today’s market. This makes the LG 360W one of the best solar panels for people trying to make the most out of their limited RV space.

However, space efficiency is not all there is to the LG 360W solar panel.

It also has a long lifespan. Degrading at a rate of 0.4% per year, this panel’s depreciation rate is 0.3% better than that of the Astronergy 325W solar panel.  It may not sound significant, but this difference means that the LG 360 retains 7.5% more efficiency than the Astronergy 325W panel after 25 years of use.

And that’s not all. LG offers you a deal like no other when it comes to solar panel warranty. While most companies offer a 10-year workmanship guarantee, LG covers the whole lifespan of its 360W solar panel, offering up to 25 years of assurance.

As for performance, the company guarantees that this panel will be 87% efficient after 25 years of use. That’s higher than the industry standard, which averages at about 80% efficiency after 25 years.

JA Solar is the world’s fourth-largest supplier of solar panels and one of the industry giants when it comes to making solar cells. They were the first manufacturer to break the 20% efficiency mark with a mono PERC solar cell in 2013, and the company has done nothing but grow since.

The JA Solar JAM6-PERCIUM Solar Panel uses monocrystalline technology to produce a power output of 295W, making it appropriate for medium-sized homes. In addition, it is made of resilient construction that can withstand wind, snow, and type 2 fire.

If you buy the JAM 6 Percium solar panel, you get to enjoy 25 years of performance warranty. With this warranty, the manufacturer guarantees that you get at least 97% of nominal power during the first year and an annual output decline of not more than 0.708% in the following years.


Hanwha Q CELLS Q.PEAK L-G4.2 360Watt 72 Cell Solar Panel
  • Q Cell technology offers anti-PID/anti-LID, hot spot protection, and traceable quality
  • Low electricity generation costs - higher yield per surface area, and lower BOS costs due to higher power classes and an...
  • Optimal yields in all weather- excellent low light and temperature behavior

The Hanwha Q-Cells Q Peak Duo-G5 320 is a standard plus solar panel. It beats most of the standard solar panels sold in the U.S. in terms of performance but lacks some of the essential features required for a premium rating.

It uses Q.ANTUM DUO technology to deliver high performance on a small package.

Q.ANTUM’s unique concept combines half-cut solar cells, a six-busbar design, and world-class circuitry to create a 320W-rated solar panel with 19.0% rated efficiency.  The sleek black finish ensures that you get a solar panel that will look good on your property.

As with all Hanwha products, you get an inclusive 12-year product warranty when you buy the Q Peak Duo. You also get a linear performance warranty of up to 25 years. This means that you are guaranteed at least 0.98% nominal power for the first year, and a maximum annual depreciation rate of 0.54.

As a result, you are guaranteed that your solar panel will be able to deliver 85% of the total nominal power during the first 25 years of use.

However, keep in mind that this solar panel is not the most space-efficient panel on the list. As such, it might not be the ideal choice for homeowners with limited roof space. Regardless, the built-in PERC technology offers solid performance at a reasonable cost.

LG is known for designing space-efficient solar panels, and the LG Neon R – 360-370W modules are no different. They boast a 21.4 percent efficiency, and quite impressively, generate 370W of output on panels that are slightly bigger than the traditional 60-cell solar panel.  This is achieved using the high-grade IBC N-type cells.

Neon R modules are premium-rated and cost more than the widely used mono P-type panels. However, the long life, ultra-high build quality, efficiency, and unrivaled performance make these modules worth every extra penny.

It’s worth mentioning that the 370W modules are currently only available in North America and Europe.  LG is also working on its technology to improve the efficiency rating and power output of the Neon R module.

Solar Panel Buying Guide

While these are the best solar panels of this year, not all will suit you.

It’s important to consider your needs and choose a panel whose features match your requirements. Below are some solar panel purchase tips.

Cost per Watt

Full-sized panels range from 275-400 watts, however, there are smaller panels specifically made for off-the-grid applications. Divide the panel price with the watts to know a panel’s cost-per-watt.


A panel’s performance warranty is a guarantee that your solar will work past the rated efficiency for the specified time. Most are rated at 80% efficiency for 25-30 years.

A workmanship warranty gives you protection from manufacturing defects and other panel’s physical problems. Make sure that the panel you buy comes with both guarantees.


This is the sun amount converted by a solar panel into useable energy. The best solar panels have a 14% to 22% efficiency range.

Temperature Coefficient

If you are in an extremely hot environment, you need to get a panel with a high-temperature coefficient as high temperature levels reduce the panel’s output and efficiency levels.

Reputation of the Solar Company

A long-serving company with a reputation of producing quality models is always recommended.
