Panasonic Solar Panels: The Complete Review for 2018

Panasonic is one of the most well-known brands in the entire world. When we think of electronics of any kind, Panasonic springs to mind. But aside from making televisions and sound systems, Panasonic has also become one of the powerhouse leaders in the field in the production of high quality and high efficiency solar panels.

In light of the fact that more people are looking to convert to solar energy, we have prepared a detailed explanation of everything you need to know about Panasonic solar panels in 2018.

Panasonic HIT Range

Back in 1997, Panasonic released their HIT range of highly efficient solar panels. They are made up of crystalline cells covered in minuscule layers of a special kind of silicon that makes them super efficient and effective. Up until recently, the manufacturing process of the solar panels all happened in Japan, Panasonic’s native country.

That is until Tesla heard about their new technology and opened a joint factory with Panasonic in the US, so they could produce all of the panels for the Tesla solar project. There is now talk of an even more advanced solar technology being releasedin the near future, which is a result of the Tesla and Panasonic partnership.

How Efficient are Panasonic Solar Panels?

Given that Tesla, one of the biggest energy giants on the planet, has built a factory to have Panasonic working alongside him is a good indication of how efficient and reliable the new Panasonic HIT range solar panels are. They have even recorded results that soar above the standard 20% efficiency level.

Which Cell Technology Do They Use?

The HIT cell structure that has been developed by Panasonic is unique and efficient. It uses both amorphous and crystalline technology to retain the power that is often lost when using traditional crystalline cell technology. HIT technology makes it possible for the solar cells to be leaders in the market when it comes to temperature efficiency. Thus Panasonic solar panels have been proven to experience minimal power losses compared to other products available on the consumer market.

Panasonic Solar Panels: Advantages

A customers’ biggest concern is often the fear that their solar panels will stop working after a while and they will have wasted a ton of money. This is without question one of the biggest factors that stops people taking the plunge with regards to going solar.

Fortunately, Panasonic believes in their products so much that they now offer a 25-year guarantee on their solar panels. After 25 years, their HIT modules have been designed to retain at least 90% of the maximum capacity they can generate. This is just one step behind the Sun Power X panels that are the industry leaders in solar power in North America.

The joint factory that Panasonic has with Tesla also means that customers will receive solar panels that have been manufactured on American soil, so you will never have to worry about your warranty not being valid or lengthy wait times if you need to replace one of your panels. When you take into account all of these factors, it is clear that their prices are also very competitive, especially the cost of their premium panels.

What About the Disadvantages?

While the HIT solar panels are competitively priced, they are still considered to be relatively expensive. This is what tends to put many customers off, especially first time buyers who want to switch over to solar power in their households.

When HIT technology first came out, it was considered to be a pioneering technology in the solar world. Unfortunately, technology evolves so quickly these days, which may mean that the once groundbreaking technology is in danger of being put on the backburner due to aging.

For the moment, HIT technology supplies the solar panel market with excellent efficiency levels as well as good quality panels, but newer technologies might eventually leave HIT behind.

Why Should You Choose Panasonic HIT Panels for Your Home?

If you are looking to install rooftop solar panels that can match the most respected brands out there with regards to warranty and quality, then Panasonic HIT panels will be an excellent choice. While they can be seen to be expensive, you have to remember that the savings, in the long run, will more than makeup for the initial financial outlay and Panasonic panels aren’t going to break the bank.

The presence of these solar panels in the industry is one that will last at least a medium term, given their partnership with Tesla. Who by the way, could have chosen any other manufacturer on the planet to team up with, but they specifically selected Panasonic.

Therefore, if the Panasonic HIT solar panels are good enough for Tesla, they will be more than adequate to satisfy the needs of the average consumer who wants to invest in high-quality solar panels.


Panasonic solar panels allow you to pack a whole load of power onto your roof. They are robust, weatherproof, and are the ideal solution to freeing yourself from expensive electricity bills each month.

There is no point cutting corners and trying to save money, only to find yourself sitting in the pitch black in the middle of a winter storm because your solar panels have packed up. These panels are also designed to perform in low light conditions,and the inbuilt water drainage feature on each panel stops water accumulating and damaging it in rainy conditions.

Micro Inverter Solar Panels: The Future of Solar Power?

More than half of all of the solar installations in the US use micro inverter solar panels. More people are switching to micro inverters, as they provide a better alternative to string solar inverters, which are traditionally the most common type of solar inverters.

The advantages of choosing micro inverter solar panels are endless,and with the increasing amount of customers installing them worldwide, they could be the future of solar power! In this article we will explore everything you need to know about them, to help you determine if they are going to be a good choice for you.

What are Micro Inverter Solar Panels?

A micro inverter is a miniscule inverter that can be directly attached to either one or two solar panels. This means that each solar panel can function independently, and DC power is converted to AC straight away at the source. The primary advantage of choosing solar panels that feature micro inverters is that every single panel you have is optimized and monitored in order to generate maximum power- regardless of what the other units in your solar setup are doing.

One of the many issues with traditional string solar panels is that they are not designed to individually overcome the fact that each panel generates a differing amount of power due to certain factors that we will explore below. This is a major disadvantage.If one panel is performing poorly, it will affect all the others in the chain.

Some of the factors that affect how well your solar panels operate include:

  • If the panel is shaded by a tree or another structure
  • If they are dirty
  • The orientation and angle of the mounted solar panel
  • Alternate Arrow Right
    Some panels might age faster than others and therefore not perform as well
  • Alternate Arrow Right
    Differences in temperature

None of the issues listed above will affect solar panels that are equipped with micro inverters. They will all be able to function at their optimal power capacity and not be affected by the other panels in your solar setup.

Advantages of Micro Inverter Solar Panels

Here are some of the key factors to consider before deciding which solar panel system will be most beneficial for your household needs.

More Flexible

One of the major selling points of these types of panels is that they can be installed on pretty much any type of roof layout. They can be placed at different tilt angles and different orientations, unlike string inverter solar panels. This makes them an excellent option if you have a roof that faces several different directions.

No Single Point of Failure

Fortunately, there are only a few drawbacks to using micro inverters

Micro inverter solar panels do not have a singular point of failure. This is a hugely important factor to consider, especially if you want a larger solar system with multiple panels. If one panel is faulty, it will not affect the rest of the system. And you will never be left without power.

Faster and Easier to Install

Because micro inverters are attached directly and individually to your solar panels, the installation process will be quicker. There is no string system to be wired together, so as the installation is faster and the cost of labor will be cheaper.


If we are being completely honest, rooftop solar panels can be ugly. This is especially true when you consider that string inverter solar panels will usually be installed somewhere near to your utility meter, which takes up valuable space as well as being rather unsightly.

With micro inverters, the majority of the solar equipment will be out of sight right up on the roof with the panels themselves.

More Efficient

Efficiency is key when it comes to selecting which kind of solar system to install. No one wants to wake up one day and find themselves without electricity,and this is what frequently happens with solar string technology. If one panel goes down, so do the rest. This is yet another favorable feature of micro inverter solar panels – they are more reliable and efficient, as they all operate independently.


If you are concerned about safety when it comes to choosing your solar panels, then micro inverter solar panels can offer you complete peace of mind. You won't be concerned about high voltage DC power on your rooftop, as micro inverters only have an AC voltage system.

Cost Effective

While it’s true that micro inverter solar panels can appear to be costlier up front, you have to remember that in the long run they will pay for themselves and are a sound investment. They will produce a greater amount of energy, leading to significant savings on a lifetime supply of power.

When we look at all of the benefits they provide, it is clear that micro inverter solar panels are an excellent choice for anyone looking to convert to solar energy. But, how about the disadvantages?

Fortunately, there are only a few drawbacks to using micro inverters

  • Currently cost approximately 20 /30% more initially than a conventional string system
  • The fact that they are on the roof means that they will be subject to adverse weather conditions, so choosing a robust and well-designed micro inverter is imperative
  • They are on the roof, which means if they need to be repaired or undergo maintenance, access could be tricky


In today’s fast-paced society, people always look for the simplest and safest solution to satisfy their consumer needs and budget. Micro inverter solar panels are becoming more popular because they are safe, effective and highly efficient.

As the world and the environment change with regards to climate change and pollution, more people are turning to solar energy to move towards supporting green, clean energy.

Ultimately, micro inverters produce more energy than their series string counterparts,and that is what is going to seal their fate with regards to the future of solar panel technology.
