The Best Way to Invest in Solar Energy? Component Manufacturers

I asked an in-house group of solar industry experts to weigh the pros and cons of different solar panel brands, and choose which ones they would install on their own homes.

After comparing all of the major brands on the market, here are the top 5 solar brands the experts recommend in 2022.

Table 1. The 5 best solar panel brands in 2022 according to experts

The most efficient solar panels on the market

The experts focused on three key criteria when making their judgement:

  • The manufacturer’s financial position
  • Brand reputation
  • Value for money

They explained that since solar panels last so long, it is crucial that the brand will be around to honor any warranty claims over the 25-year lifespan of the panel.

Their choices are divided into two categories of solar panels: three are premium solar panels, and the other two are value solar panel brands.

Are Tesla Solar Panels Monocrystalline

Yes, all of Teslas solar panels are monocrystalline. Monocrystalline solar panels have black solar cells made of single crystals as opposed to polycrystalline panels that are blue and made from multiple silicon crystals. While this makes Tesla solar panels more expensive, they are certainly far more efficient.

Get The Best Panels Installed By The Best Solar Companies

Every solar panel on this page – whatever its ranking – is a high-quality, Tier 1 solar panel brand. Installing a solar power system with any of these solar panels should result in an efficient, high-performance setup that can power your home for 25 years, or longer.

Picking the best solar equipment is only part of the equation though. Equally, if not more important, is picking the right solar company to install the solar equipment.

The solar installation company is responsible for designing a system that meets your needs, and they will be your point of contact for any performance or warranty issues you encounter. Make sure the company you choose is one of the best solar installers near you.

Top 5 American Solar Panel Manufacturers In 2020

The majority of photovoltaic solar panels sold in the United States arent actually made in the US. In the past few months, however, several Asian solar companies, most notably those in China, have begun moving operations and manufacturing solar panels in America.

Why? Because of an import tariff on solar panels implemented by the Trump administration. To incentivize US manufacturing, President Donald Trump introduced a 30% tariff on imported solar panels and the cells used to manufacture them. Because of this, some US solar energy companies have begun manufacturing at new US-based facilities.

This list of American solar manufacturers includes many of the leading solar brands you can buy in the US and includes Hanwha Q Cells, Panasonic, LG Solar, Jinko Solar, and SunPower.

Heres a rundown of the five best solar panel manufacturing companies in the US.

Q3 Why Buy Solar Panels

As mentioned, there are many benefits to buying a solar panel from a reliable and trustworthy company. Aside from solar panels, many solar companies also provide battery storages that save electricity for hours, which can be very useful when there is a power failure or any other issue.

Aside from this, by using the sunlight to get electricity, you can save more money, as your electricity bill will be of a lower cost. In addition, with the development of technology, the world is looking for more sustainable methods for generating electrical power to protect the environment.

Also, solar panels can add value to your home. Studies have shown that homes that have solar systems can sell for a lot more than the ones that do not. By using solar, the greenhouse gas emissions are reduced, meaning there is less pollution, too.

What Is The Industry Standard

Product Warranty

Most solar companies offer at least a 10-year materials warranty,

Performance Warranty

Most solar panel manufacturers back their product with a linear performance warranty for 25 to 30 years.

The linear performance warranty guarantees that the performance of a panel will stay above a specified degradation rate .

This assures you that the panel will continue to have the capability to produce a specified percentage of power during the warranty period.

On average, a solar panels performance warranty will guarantee 90% production at 10 years and 80% at 25 years.

Split Modules With Half

Over the last few years, most leading manufacturers have shifted to using half-cut or half-size cells rather than the traditional full-size square cells. The square cells are laser cut in half and assembled into two groups of cells that work together in parallel. This cell configuration has multiple benefits including increased efficiency due to lower resistive losses through the bus bars as each group of cells operates at the same voltage but half the current. The lower current also results in lower cell operating temperatures helps reduce the potential formation and severity of hot spots due to localised shading, dirt or cell damage. Additionally, since each group of cells is half the size, the busbar distance is reduced by half which means smaller busbars can be used resulting in less busbar shading losses and increased efficiency.

More recently, a number of manufacturers such as Trina Solar have started producing extra-large 210mm square cells which can be cut into three sections, known as 1/3-cut cells. These large format cells are used to produce high-powered panels up to 600W.

The Hanwha Q Cells Q.Peak Duo G6 panel uses half cut mono PERC cells with 6 round wire busbars

Do Solar Panels Require Maintenance

When weighing solar energy pros and cons before making an investment, one of the most common questions that homeowners have is whether their solar panels will require maintenance.

For the most part, all the hard work comes on the front end. Installing a home solar system requires in-depth knowledge of electronics as well as solar power, and in most cases, a solar installation will take a few days. We recommend outsourcing this to trained solar professionals.

Once your system is in place, however, the level of upkeep required is fairly minimal. Besides routine cleaning, you shouldn’t have any issues that require maintenance with your solar panels for 20 to 30 years. And if you do run into an issue, your warranty will hopefully cover it.

Q2 How To Know If Your House Is Suitable For A Solar Energy System

This is a common question asked by people who are considering getting a solar energy system. What you can do is contact the solar company and provide the necessary information to get a quote or talk with a representative that can examine your space and provide you with details and a custom plan.

Luckily, the solar companies on our list are using technology to estimate the conditions and come up with a suitable solution. You can also look for online tools designed to determine the amount of sunlight you get per year and how much space you have for a solar energy system. The ideal conditions for a solar system are a large roof with no obstructions, a 30-degree pitch, and one that is in good condition.

    Tests Performed By Pvel And The Failures They Expose

    One of the Best Solar Companies in La Jolla, California ...

    The PVEL tests are smaller in number but more severe than the UL and IEC tests. For example, the PVEL thermal cycling test involves 600 cycles in an environmental chamber that cycles between hot and cold temperature which is 3 times as many cycles as the IEC test.

    Heres a list of the tests performed:

    • Thermal cycling: Solar panels are baked at +85°C, then frozen down to -40°C in an environmental chamber for 600 cycles, or about 84 days.
    • Damp heat: The panels sit in a chamber at a scorching 85°C with 85% humidity for 2,000 hours, simulating the effect of operating in damp conditions for many years.
    • Mechanical loading: For this punishing test, the panels are loaded with 1,000 Pa of force 1,000 times, then cycled between -40°C and 85°C 50 times, subjected to the damp test for 20 hours, before finally being frozen to -40°C.
    • Potential-induced degradation: Solar panels can experience a type of degradation called PID that happens when theres a large voltage difference between the solar cells and the metal frame of the panel. This PID test applies up to -1,500 volts to the panel under damp heat for 192 hours.
    • Low light testing: The output of a solar panel drops when theres less light, of course, but the drop isnt linear: solar cells are less efficient in low light. They also lose efficiency when hot. Both low light and high temperatures are tested to show which panels perform best in these conditions.
