Why Do I Like It?

While neither being the best performer nor the least expensive high-end solar panel for home use, the SIL-370 is somewhat of a middle child. For a reasonable price, you get reasonable performance and sleek all-black aesthetic appeal.

8. Trina Solar Residential 365W Module — Best Value on Budget

Wattage: 365W | Efficiency: 20.6% | Warranty Period: 25 years

The TSM-DE06X solar panel from Trina Solar owes its 365 watts of output power and 20.6% conversion efficiency to Multi Busbar and half-cut cells technology.

On the outside, Trina Solar panels provide a seamless visual experience as thinner inter-cell connections almost disappear at a distance, leaving behind the desirable all-black look. 

If you own a car, you already know how corrosive bird droppings can be. This is why these panels feature a durable hardened glass cover that is resistant to salt, acid, and ammonia, extending the life of your solar system.

Trina Solar offers a standard 25-year product warranty and a 25-year power warranty. At that point, you can expect the power to drop to 84.9%.

Pros

  • Efficiency of 20.6%
  • Low temperature coefficient
  • Half-cut cells for improved conversion
  • Moderately priced
  • 25-year limited warranty

Cons

  • 84.9% output after 25 years

Why Do I Like It?

9. AXITEC Solar AXIPREMIUM XXL — Best for Boosting Property Sales

Wattage: 415W | Efficiency: 21.25% | Warranty Period: 15 years

Using half-cut cell technology and select materials this powerhouse of a panel achieves 415 watts of power output and 21.25% of conversion efficiency

The AXIPREMIUM XXL panels come in a distinctive deep blue color, protected with hardened, low-reflection white glass, while the innovative frame design provides increased stability.

Unfortunately, after 25 years of use, the output of these panels is expected to drop to 85%. 

So, the temperature coefficient of -0.28 is the only perk to write home about, besides the competitive price.

Sadly, these solar panels for homes come with only 15 years of warranty.

Obviously, this is a major downside as most of the competitors are offering 25 years of warranty.

Pros

  • Efficiency of 21.25%
  • Low temperature coefficient
  • Half-cut cells for improved conversion
  • Competitively priced

Cons

  • 85% output after 25 years
  • 15-year warranty

Why Do I Like It?

Not everyone is looking for a solar system to last for a lifetime. Inexpensive, high-efficiency solar panels might be just the thing you need to offset your utility costs — and increase the resale value of your property.

10. JA Solar JAM60S20 — Best Low-Cost

Wattage: 390W | Efficiency: 21% | Warranty Period: 12 years

The 390W half-cell module from JA Solar uses the advanced PERC cells (Passive Emitter and Rear Contact) which use an additional layer on the back. This feature allows your panels to capture more sunlight and effectively turn it into electricity.

Thanks to this technology, the JAM60S20 panels reach an efficiency of 21% and a temperature coefficient of just -0.27 — both properties put JA Solar panels on terms with the competition.

Unfortunately, these panels have a significantly worse degradation rate than the competitors — the power drops to 83.1% after 25 years.

Don’t get me wrong — this is fine for the industry-standard but not good enough for the best of the best. .

Besides, a 12-year product warranty is much less than what we expect from top-tier manufacturers, and cannot but raise an eyebrow.

Also, if you’re concerned with the aesthetic appeal of your home once you upgrade it to solar, you might have to check other options.

The JAM60S20 comes with rather thick aluminum frames that are hard to conceal.

On the upside, these panels are very competitively priced.

Hint: Four times less than SunPower Equinox!

Pros

  • Efficiency of 21%
  • Very low temperature coefficient
  • PERC cell technology for increased conversion
  • Competitively priced

Cons

  • 83.1% output after 25 years
  • 12-year warranty

Why Do I Like It?

Best Solar Panels for Home Buying Guide 

7 Things That Make A Solar Panel Best for Homes

Now let’s take a look at what makes these 10 solar panels for home the very best products you can buy today. 

Unparalleled Efficiency

A solar panel efficiency is a rate by which the panel converts sunlight into electricity. You should always go for the highest efficiency rating because it means your panels will capture more sunlight for the same period of time.

This is especially important if you live in the Northeast or another part of the world that isn’t too known for its sunny weather.

Looking at the comparison table, we see that SunPower Equinox, Canadian Solar HiHero, and REC Alpha Series are killers in this category.

While panel efficiency shouldn't be your only parameter, make sure that the panel you choose yields at least 20%. 

Low Temperature Coefficient

Did you know that too much sun can actually slow down your solar operation? 

But how’s that possible? It’s solar panels we’re talking about. The more the sunlight the better, right? 

Well, actually, it’s not sunlight the problem, but the heat. Solar panels are electronic equipment after all and work most efficiently when kept cool. 

The temperature coefficient tells you how much your solar panels’ performance will drop during hot summer days. 

For every degree above 25° C (or 77° F), your solar panels’ electricity output will decrease by the temperature coefficient. 

In other words, a lower temperature coefficient is always better. 

For example, Panasonic EverVolt Series solar panel has a temperature coefficient of -0.26%. So, if your solar panel temperature increases by one degree Celsium, its electricity production will fall by 0.26%. 

If the temperature increases to 35° C (or 95° F), Panasonic will produce 2.6% less electricity. 

I can’t stress enough how important the low temperature coefficient is, especially if we know that the surface of a roof can get much hotter than the air around when the sun is directly above.  

Respectable Wattage

Wattage is another word for power or the potential electrical output of a panel under ideal circumstances. The higher the wattage the more electricity your panel can produce during a day. 

While higher wattage is always better, there are a few things you must know. 

Higher wattage panels are better for smaller roofs, as you can get the same output with fewer panels. 

However, higher wattage always means a higher price tag, so if you have plenty of space, you needn’t necessarily go for the most powerful option. A home solar system is already a hefty investment. 

When shopping for a home solar system, make sure to compare the panel’s efficiency and wattage in one take. High-efficiency, high-wattage is an ideal combo, but again, if you have enough roof space, you can go lower on wattage. 

Competitive Warranty

Solar panels come with a warranty that protects buyers against equipment failure caused by environmental factors and manufacturing defects. 

The industry standard for panel material warranty is 10 years, while LG Solar, Panasonic, SunPower, and other established brands regularly offer 25-year warranties against manufacturing defects for their top-shelf panels. 

However, you need to know that there is another warranty related to solar panels — the annual degradation rate. 

It shows you how much the panel performance will drop at the end of the 25 year period. 

The leading brands like LG, SunPower, and Panasonic guarantee that their solar panels will remain above 90% performance after 25 years.

Brand Value

When choosing a solar panel brand you also need to make sure that the company you go with will still be around to honor your warranty after 10 or 15 years. 

In this sense, larger corporations like LG, Panasonic, and SunPower are safer bets than solar startups that are still building their name. 

Larger companies are less likely to go down, but these days many smaller players are aggressively edging their way into the market, offering competitive prices and impressive performance. 

Solar Panels for Home Buying Guide

Panel-Appeal

With more and more people choosing to go solar, homeowners are increasingly interested in aesthetically-pleasing panels that won’t ruin their home’s curb appeal. 

Тhis is especially the case in neighborhoods with some HOA (Homeowners Association) requirements for solar arrays and for homes that need panels that face the road.

In this sense, many homeowners choose black solar panels as the most elegant solution, but not all black panels are made the same.

Most silicon cells are dark blue or black — those are the squares you see on the face of all solar panels. The space between these cells is where you can see the back sheet. If you choose panels with a black back sheet, you get a much sleeker, all-black look.   

The panel frame color is also important. If you want to pursue the all-black theme, you can as well choose a black panel frame. 

What’s more, Trina Solar manufactures frameless solar panels that have no back sheet either. These solar panels are supported entirely by their glass coverings. 

In my opinion, these are the best-looking solution for the street-side of your roof, as well as carports, awnings, and other locations where aesthetics is a priority. 

Unique Advanced Technologies

The solar panel market is tough, so solar companies are looking for every opportunity to take an edge over competitors.  

LG NeON® series panels, for example, use an anti-reflective coating that reduces optical losses from sunlight that is reflected back from the glass cover. 

SunPower is a company that is heavy in unique technologies. Each of the Equinox solar panels comes with a built-in microinverter, which not only optimizes the electric output but also brings you greater stability for the entire system. 

Panasonic EverVolt solar panels use half-cut cells with heterojunction technology that improves solar conversion. 

REC Alpha Series are pioneers of gapless cell connection technology that doesn't require invasive soldering, which reduces the risk of microcracks developing over time. 

Factors That Affect the Performance of Solar Panels on Your Roof

Does my Roof Get Enough Sunlight?

If you live in an area that gets a lot of sunny days throughout the year, you can expect more yield from your solar panels. 

However, when talking about sun exposure, we need to consider the number of peak sun hours.

A peak sun hour is an hour during a day when the sunlight intensity reaches an average of 1000 watts/meter².

The number of peak sun hours can not only affect the performance of solar panels on your roof but also let you go with a smaller (and less expensive) solar system. 

For example, Maryland has between  3 — 4 peak sun hours, while Utah has between 6 — 7.

In ideal conditions, solar panels in Utah will produce two times more electricity than the same ones installed in Maryland.  

To get a quick idea of how your location ranks in solar exposure, check out these solar irradiation maps developed by the National Renewable Energy Laboratory (NREL). 

Is There a Shade During the Day?

Here’s the deal — Your location can have 365 sunny days in a year, but that means little if your roof is in the shade for the better part of the day.

The thing is that surrounding canopies, buildings, and even other roofs can seriously limit your solar panels’ performance. 

Sure, the most advanced solar panels can produce electricity even in the shade, but the output is not nearly as close. 

For optimal solar gains, make sure that your roof is exposed to direct sunlight for the most part of the day. 

Does My Roof Face The Right Way?

Plenty of sunlight and minimum shading is always good, but if you want to max out your panels’ performance, your roof needs to face the right direction. 

So what is the right direction?

If you live in the northern hemisphere, your roof needs to face S, SW, or W. On the other hand, if you live below the equator, your solar panels will get the most of the sun if the roof faces N, NE, or E. 

How About the Shape of the Roof?

An ideal roof for a solar panel needs to be flat, not too steep, and free from architectural features like chimneys, gables, and skylights. 

An average home needs at least 15 solar panels, and having a flat and spacious roof takes a lot of hassle out of the equation.

Got to Keep Them Clean

One of the best things about solar panels is that once they’re up and running, almost no maintenance is needed on your part. 

However, you need to wipe them down from time to time to remove dirt and debris. Dust, pollen, and leaves may stick to your panels and reduce their ability to absorb sunlight. 

You should wipe down your panels more often after intense storms, and especially in spring and fall, when there are all kinds of stuff flying around. 

To keep your panels sparkling clean, use lukewarm water, mild soap, and a non-abrasive sponge. Finish the cleaning with a soft squeegee — the same way you’d clean your car’s windshield.  

If your part of the country gets some snow in the winter, make sure to remove it as soon as it stops. Snow cover not only blocks the sunlight from reaching the solar cells but also puts additional stress on the panel surface.

How Many Solar Panels Do You Need?

To answer this, I need to know your: 

  1. Energy usage
  1. The amount of sunlight your location gets
  1. The type (wattage) of solar panels you’re looking to buy. 

You can easily estimate your home’s energy usage by comparing several bills from different seasons. 

It’s important to take bills from different seasons because your HVAC system might be using more energy in certain months. 

It would be best if you can just add up your monthly bills from the past year and divide them by 12. That’s your average energy usage. 

So if your home uses 11,500 kWh per year, your average energy usage is 958 kWh/month.

Next, we need to find out — 

The Amount of Sunlight in Your Location

The U.S. covers a large area and different climate zones, so there are large variations of peak sun hours between states. 

The states with the highest average peak sun hours are Arizona, California, Nevada, and New Mexico — between 5 and 8. 

Alaska, Indiana, Michigan, and Ohio, on the other hand, have the least peak sun hours — between 2 and 3.5. 

Let’s say you live in Oklahoma and get on average 5 peak sun hours a day. Multiply that by 30 and you get 150 monthly peak sun hours. 

So, in Oklahoma, you can hope for 150 kWh of electricity with 1 kWh of solar panels

Now we need to find out what size solar system you need. 

Your monthly electricity usage (kWh) ÷ Monthly peak hours in your area (h) = The solar system size  (kW)  

We’ve already estimated that your monthly electricity usage is 958 kWh and the number of monthly peak sun hours is 150 in your location:

958 kWh ÷ 150 h = 6.39 kW ~ 7kW

We know now that you need a 7kW solar system. 

Finally, let’s say you choose the most powerful panel on the list, the Canadian Solar HiHero 430W.

And the number of panels you need is:

(Solar system size × 1000) ÷ Power rating of the solar panels

= (7 kW × 1000) ÷ 430 W

 = 7000 W ÷ 430 W

= 16.27 ~ 16

And there it is — you need 16 solar panels for your home!                                         

Are Solar Panels Worth It?

Solar panels for home use are becoming increasingly popular, as more and more homeowners are looking to offset or eliminate their electricity bills. 

But are solar panels worth it?

Even today, a home solar panel system is a big investment, so let’s put things this way — 

When do solar panels make sense?

My House Gets Plenty of Sunlight

If you live in a part of the country that gets a lot of sunny days throughout the year, your home is a prime candidate for solar panels. 

As we’ve seen in the previous section, the number of peak sun hours can even allow you to choose a smaller solar system, which also means fewer solar panels.

For maximum solar gains, you also need to make sure your roof is not in the shade most of the day.

I Have Plenty of Space on My Roof

An average home solar system consists of at least 15 solar panels, and an average size of a single panel is 68 × 40 inches. 

That’s a lot of space!

In an ideal scenario, you’ll have a wide, flat roof that is free of vents, chimneys, and skylights.

If your roof has two levels, that also shouldn’t be a problem. 

On the other hand, if your roof is too small, you may have to go with the most efficient solar panels, which are often the most expensive option. 

My Roof Faces the Sunny Side

Your solar panels will perform at their peak only if your roof faces the sunny side. But which one is the sunny side? 

It’s fairly simple.

In the northern hemisphere, it’s the south and southwest. Below the equator, it’s north and northeast.

I Already Pay a Lot for Electricity

The more you pay for the utility power, the more your solar savings can be. If you live in a part of the country that has high electricity rates, you should definitely consider going solar. 

For comparison, Louisiana has one of the lowest electricity rates, at only $0.09 per kWh. Homeowners in Connecticut, on the other hand, pay $0.22 for the same kWh.

My State or City Offer Solar Incentives

Home solar system definitely makes more sense if you can apply for state or local incentives, rebates, and tax exemptions. 

In 2022, homeowners can still apply for the federal solar tax credit that allows you to deduct 26% of the cost of your solar system from your federal taxes. 

Apart from this federal incentive, you should also ask around for local incentives. This Database of State Incentives for Renewables & Efficiency (DSIRE) is a great resource for finding local energy rebates. 

And now listen to this — You can leverage the available incentives to make up for low peak sun hours in your area. 

This is the reason why the Northeast has so many solar panels for home use — those states offer robust solar incentives to make up for the rainy days. 

Final Thoughts 

With competition so fierce, it was hard to select a single winner. However, after giving it much thought, I can say that the best solar panel for home use is the LG NeON® R. 

This solar panel is a well-rounded choice that rocks a lot of power —  and holds on to it even beyond the 25-year warranty period. 

The LG has a slightly lower efficiency rating than my second choice— Sunpower Equinox, but it packs a lot more power. 

This makes the NeON® R a great option for smaller roofs, where you need to pack all the power you can into a limited area. 

Finally, this solar panel has no visible grid on the front, which makes it an attractive all-black option, suitable even for the most demanding HOA neighborhoods.
