How to Pick the Best Solar Panels for Your Project
There are a handful of factors that influence how good panels are. Here are the main things you should look at when you research solar panels.
Cost per watt
FREE Solar Panels GuideLearn More »
For most people, budget is the primary factor influencing decisions during the design process.
Panels come in all different sizes. Full-sized panels typically fall in the range of 275-400 watts, though there are also smaller panels for specialty off-grid applications.
The great equalizer is cost-per-watt. Divide the panel price by how many watts it outputs. You’ll get a “true” pricing number, which you can use to compare all panels on a level playing field.
There are two different warranty categories – performance and workmanship.
The performance warranty guarantees your panels will work above their rated efficiency for the duration of the warranty. Most manufacturers promise their panels will work at or above 80% efficiency after 25 years.
25 years is the industry standard, but a few manufacturers offer longer performance warranties of 30 years.
Then there’s the workmanship warranty. This protects against manufacturing defects and other physical problems with your panels.
The workmanship warranty is shorter than the performance warranty. A generous workmanship warranty gives a great indication that the manufacturer knows they are putting out a reliable product.
The industry standard workmanship warranty is 10 years, with some companies offering 20-year guarantees.
A solar panel’s efficiency rating refers to the amount of sunlight the panel can convert into usable energy. 14-22% is an acceptable efficiency range for panels produced by major manufacturers.
Solar panels are tested in ideal conditions. When manufacturers measure panel output, they perform tests inside a climate-controlled factory.
Obviously, the real world is going to introduce less-than-ideal conditions. During those sweltering days in the dead of the California summer, your system will lag behind its rated efficiency.
The impact temperature has on true panel output is the temperature coefficient. The coefficient measures how much efficiency is lost for each degree above or below ideal test conditions.
We’ll give an example in Celsius, because that’s what most manufacturers measure: energy loss per 1°C temperature change.
For example, let’s say a panel was tested at 45° C, but its current temperature is 55° C. If the temperature coefficient is 0.4% Wp (Watt power), you can multiply that by the difference in temperature (10° C). That panel is operating 4% below its rated efficiency on that particular day.
There are separate temperature coefficients for voltage, amperage, and wattage. Certain types of solar panels like monocrystalline can perform slightly better at higher temperatures.
The temperature coefficient usually isn’t the most important variable to focus on unless you are in an area that gets extremely hot. This is because heat reduces the efficiency of your solar panels, making them operate at a reduced output.
The longevity and reputation of the panel manufacturer play a part in our recommendations. What good is a warranty if the company goes out of business before they get a chance to honor it?
For that reason, we look at companies with a stable track record in the solar industry. Every product on this list is produced by a major manufacturer that we don’t expect to disappear any time soon.
Underwriters Laboratories is an organization that has been around for over 100 years. UL sets standards and performs safety tests to ensure products are safe for public use.
Solar panels must be certified to UL 1703 standards if they are being installed on your home.
What are the best solar panels on the market in 2020?
Without further ado, here are the best solar panels you can buy in 2020 for a variety of applications. The info in this article is current as of 6/30/2020.
Best Value Solar Panels: Astronergy 365W
- Astronergy CHSM6612M-365 Silver Mono PERC Solar PanelAstronergy 365 watt Module Silver Mono PERC CHSM6612M/HV – 40mm Frame$257.00
- Cost: $257 (70 cents per watt)
- Workmanship warranty: 10 years
- Performance warranty: 25 years
- Efficiency: 18.9%
- Degradation: -0.7% / year
- Temperature coefficient: -0.376% Wp
- # of cells: 72
- Cell type: Mono PERC
Looking for panels that won’t break the bank? Astronergy makes the best solar panels you can get from a pure value perspective.
Of the major module producers, Astronergy has the lowest cost-per-watt panels we’ve found. Their 365W panel retails at $257 (at the time of publication), which shakes out to 70 cents per watt.
A few of our employees run their home systems on Astronergy panels, and we also picked them for the system that powers the Unbound Solar flagship office.
Their 17.7% efficiency is very respectable at this price point, and the warranty is on par with industry standards.
Astronergy also sets their warranty program apart from other companies by offering third-party insurance. Should they ever go out of business, the warranty would still be valid from the third-party provider.
That’s more for peace of mind than anything. Astronergy is a part of one of China’s largest electronics manufacturers. We expect them to be around for a long time to come.
But the extra bit of insurance on the warranty coupled with the low price point makes these panels a popular choice.
Best American-Made Solar Panels: Heliene 320W
- Cost: $256 (80 cents per watt)
- Workmanship warranty: 10 years
- Performance warranty: 25 years
- Efficiency: 19.26%
- Degradation: -0.7% / year
- Temperature coefficient: -0.38% Wp
- # of cells: 60
- Cell type: Mono
Among the American solar panel manufacturers, Heliene is our top pick. Based out of Sault Ste. Marie, Ontario, they assemble high-efficiency panels with factories in the USA and Canada.
With solar panels getting cheaper all the time, the price gap between imported and American-made panels has shrunk considerably. Imported 365W Astronergy panels now sell for 70 cents per watt, while American manufacturer Heliene sells 320W panels at 80 cents per watt.
Compare that to the premium LG panels featured in the next section, which go for $1.34 per watt.
Looking at the price distribution, Heliene’s place in the market is clear. Their prices are competitive with imported panels, and they also give the high-efficiency models a run for their money on output (while blowing them out of the water on the price tag).
If you want to pick up some high-efficiency panels at a competitive price (and support American-made goods in the process), Heliene is the go-to choice. We recommend both their 320W (60-cell) and 365W (72-cell) panel.
Best Premium Solar Panels: LG 375W
- LG NeONR LG-375Q1C-V5 Mono Black Frame Solar PanelLG Solar 375 NeONR, Mono, Black Frame Module – LG-375Q1C-V5 – 40mm Frame
- Cost: $513 ($1.36 per watt)
- Workmanship warranty: 25 years
- Performance warranty: 90.8% efficiency after 25 years
- Efficiency: 21.7%
- Degradation: -0.4% / year
- Temperature coefficient: -0.3% Wp
- # of cells: 60
- Cell type: Mono
LG doesn’t just make solar equipment; they’re one of the leading electronics manufacturers in the world.
We feature LG’s 375W panel in our premium packaged systems. They are super space-efficient, packing more output into a 60-cell panel than most 72-cell panels on the market are capable of producing.
Every solar project is different, and some people have the challenge of building a system in a compact space. For example, you may only have room for 10 panels on your roof. These LG panels will help you squeeze as much output as possible out of the limited space available to you.
They also have a long lifespan. At -0.4%/year, the degradation rate of these panels is 0.3% better than our featured Astronergy 365W panel.
That may not sound like a lot, but when you work the math out, it means LG panels will retain 7.5% more efficiency than Astronergy panels at the 25-year mark.
And LG’s solar panel warranties are a thing of beauty.
Where most companies aim for a 10-year workmanship warranty, LG covers the full 25 years.
On the performance warranty side, LG ensures their panels will still be 90% efficient after 25 years. That’s a stronger promise than the standard 80% after 25 years.
What are the best solar panels for off-grid systems?
We get this question a lot: is there any difference between panels for off-grid and grid-tie properties?
There is a bit of nuance to the answer.
The panels themselves can always work regardless of system type. There is no such thing as “off-grid panels” or “grid-tied panels” specifically.
However, panels must be paired with other components and sized accurately, especially in off-grid systems.
Historically, off-grid systems have used PWM charge controllers, which required that you match 12V solar panels with a 12V battery bank.
Now, most modern off-grid homes will use an MPPT charge controller, which can adjust the incoming PV voltage to work with almost any solar panel.
However, there are still string sizing considerations based on the panel and charge controller specs. All of the components must be supplied with the appropriate voltage and current. Batteries add another layer of complexity for off-grid systems, since the array must be sized to sufficiently recharge the batteries without overcharging them.
There are also a handful of panels that are designed specifically for off-grid applications:
Best Solar Panels for RVs / Mobile Applications
Solar is also a great solution for mobile applications like RVs and boats. But you’ll need smaller panels to work around any space constraints.
The solution for this is Sol-Go 115 watt flexible panels.
The lower profile helps you find the right configuration with limited space available. And since these panels can bend up to 30 degrees, they can flex around curved surfaces to make the most of the space you have.
These panels are lightweight, easy to install and perform well in low light. They’re built to adapt to rough and changing conditions that come with living life on the road.
The last category we’ll look at is the best solar panels for small-scale remote applications.
These tend to be used to power remote equipment for a variety of industries:
- Security & surveillance
- Oil & gas
- Water pumping
- Utility monitoring
A lot of times this equipment is in a remote location (like at the top of a mountain or floating on a buoy in the middle of a lake) and you need a small, self-contained system to keep it running.
We would recommend both Solarland and Ameresco, depending on the application. A few examples:
- Solarland SLP175S-12 Silver Mono 12 Volt Solar PanelSolarland SLP175S-12 175 watt Mono module, 12v, MC4 – 35mm Frame$324.00
- Solarland 175W panel – $324
- Ameresco 90W panel – $185
This represents the high end of the output range for 12-volt panels. Both companies offer a variety of 12V panel options ranging from 1W to 175W. Solarland also has 24V options, including one that goes up to 190W.
That’s it for our recommendations! We think these are the best solar panels you can get for your money in 2020, but prices and product configurations will change rapidly as technology improves.
As you do your research, seek out efficient panels from trusted manufacturers, and calculate the cost-per-watt so you can compare products on a level playing field.
If you follow these guidelines, you’re sure to find the right solar panels to power your system.
HOW TO BUY SOLAR PANELS
Are you thinking about buying a solar panel system but don’t know where to start? You came to the right place!A Really Great Read
Before we dive in to the specifics of solar panels (a.k.a. PV modules, solar electric panels), let us remind you that energy efficiency and conservation are the best ways to reduce your energy foot print and your electrical bill (see our Energy Efficiency and Your Home article). Please actively explore and incorporate all avenues of efficiency before pursuing a home solar panel system. That being said, solar power is an exciting clean-energy option that is becoming more and more popular. Solar electricity is a fascinating topic. To really feed your curiosity, we highly recommend the book PHOTOVOLTAICS: DESIGN & INSTALL MANUAL.
What shapes, sizes and types do solar panels come in?
Solar panels vary in length and width and are often about 2 inches thick. They are generally about 30 pounds or less, but the larger solar panels can be cumbersome to carry onto the roof. We carry a wide selection of solar panels for home use: framed, foldable, and rollable.
- Framed solar panels are the industry standards. They are the most cost effective and applicable for most home solar panels applications.
- Foldable solar panels are lightweight (less than 5 pounds) and can fold up and fit easily in a backpack.
- Flexible (or rollable) solar panels are also lightweight but bulkier than the foldable panels. Many people use these rollable solar panels on boats because they are durable and can be easily stowed after use.
Generally thin-film laminate type of solar panels (foldable & flexible) are more expensive per watt and require more square footage to produce the same wattage of an equally sized framed module.
What size solar panels do I need for my home and how many?
The number of solar panels you will need depends primarily upon the amount of electricity you are trying to produce and the insolation in your area. Solar insolation can be thought of as the number of hours in the day that the solar panel will produce its rated output. This is not equivalent to the number of daylight hours. Read more about insolation in our How To section and get an idea of the insolation in your area: Solar Insolation Map – USA.
You’ll find solar panels in a variety of wattages. Watts are the main measure of a solar panel, along with nominal voltage. For a rough idea of how many watts of solar panels you will need for your home, start by dividing your electrical usage (in watt-hours per day) by the solar insolation in your area. Bump that number up by 30-50% (to cover system inefficiencies) and you’ll have an idea of the number of watts of solar panels total you will need. If that number is more than 1000 watts, you are talking about $4K to $8K or more for the solar electric system. (Could we take this opportunity to mention the importance of energy efficiency again?!) If you could still use a little help with the math, please give us a call and tell us how much electricity you are trying to produce (in kwh/month or watt-hours/ day) and your location, and we’ll help get you started.
What types of solar panels are there?
Most solar panels can be classified as monocrystalline, polycrystalline or amorphous. This is based on the silicon structure that comprises the cell. It’s not quite as complicated as it sounds. Basically a 100 watt monocrystalline solar panel should have the same output as a 100 watt polycrystalline solar panel and a 100 watt amorphous solar panel. The main difference is the amount of area which the solar panel occupies. Because the monocrystalline structure is more efficient than amorphous (and only very slighlty more so than polycrystalline) in turning sunlight into electricity, the amorphous solar panel of the same wattage will be physically larger. By the way, when talking about efficiency of solar panels, keep in mind that solar panel efficiency is still only about 13-18% efficient in turning sunlight into electricity. Often amorphous solar panels are less expensive than the crystalline panels. If space is not an issue, then an amorphous panel could be a great option. Additionally, amorphous solar panels perform better than crystalline solar panels in very hot temperatures and are also slightly more tolerant of partial shading.
Solar Energy for Home Heating & Cooling
Please keep in mind that solar panels produce electricity, and should not be used to produce electricity for heating or cooling sources. If heating is your main issue, be sure to check out Solar Air Heaters and Solar Water Heaters. Solar air heating and solar water heating are examples of solar thermal technologies which produce heat, but not electricity (and are much more cost effective than solar panels). While solar electric panels are not an economically feasible choice to power your air conditioning, a solar panel can power an attic fan that can help reduce the amount of time you use your AC.
Locating your Panels – Very Important!
A key factor in the effective use of solar electricity is proper placement of the solar panels. Make sure to locate the panels where they will receive full sunlight between the hours of 10 am and 3 pm. Be sure that the solar panels will not be shaded by shadows from tree branches, chimneys, other structures, etc. Once again – NO SHADE! You will be mounting the solar panels on the roof, the ground or a pole. For more information on the proper placement solar electric panels, please checkout the How To for Solar Panel Mounting article.
How Long will Solar Panels Last?
Solar panels use the sun’s light to generate electricity. They generate electricity during sunny daylight hours and can be used in a system with batteries so that the electricity can be used at other times as well. Also known as Photovoltaic (PV) modules, solar panels are the main component of a solar electric system. Along with an inverter, mounting system, batteries and Solar Charge Controllers, solar panels can produce electricity to power the energy efficient appliances and lights and appliances in most households. Solar panels themselves generally last over 25 years, and require little maintenance. Many of the first solar panels produced in the 50s are still in use today. Many of the solar panels have a 20 year warranty or more. A common warranty states that the panels will produce at least 80% of their rated power after 20 years.
What else will I Need with a Solar Panel?
In addition to the solar panel mounting hardware, there are additional components that you will need for a safe installation. If you plan on using just one solar panel in a battery based system (an off-grid system), you will need a solar charge controller and overcurrent protection to protect each major component of your system: solar panels, solar charge controller, deep cycle batteries, and inverter. If you plan on using more solar panels in your system, you will also need to safely wire the photovoltaic solar panels together and to the charge controller. An easy and safe way to do this is by using MC (multi contact) connectors. These connectors connect to the cables coming from the solar panel and can be cut in half to expose bare wire. Combiner & pass-through boxes are used to collect the bare ends of the wire from multiple solar panels; then from the combiner box you can run just one set of wires to the solar charge controller. For each series string of solar panels, you will need an appropriate sized breaker.
That’s a lot of components to figure out! If after reading all this you are a little confused but even more excited about solar energy, what’s next? Well, you can read more about solar panel systems. Also, our AltE U offers in-person workshops in Massachusetts and Ohio, as well as free education online videos. If you are considering installing your own solar electric system or installing PV (photovoltaic panels) as a business, be sure to check out our series of three classes beginning with our Basic Photovoltaic and Site Assessment class.
