What is the Highest Wattage Solar Panel? – How to Efficiently Generate Solar Energy

What is the Highest Wattage Solar Panel

Short on Time? Here’s The Article Summary

The article discusses the latest advancements in solar panel technology, focusing on the highest wattage panels available. Currently, the most powerful panels for consumers have a 500-watt rating, although there are rumors of even higher wattage panels in development. These panels are expensive due to limited supply. The article advises against paying inflated prices for the latest technology, suggesting that more affordable 400-450 watt panels are a better option. It emphasizes the benefits of chaining together lower-wattage panels to achieve the same or greater power output as a single high-wattage panel, at a lower cost.

The article also discusses the advantages of solar panel kits, which come with all necessary components for a solar power system. It highlights two specific kits: a 1,200-watt kit with four 300-watt panels and a beginner 400-watt kit with a 100-watt foldable panel. The article concludes by recommending careful consideration of factors beyond just wattage when choosing solar panels, such as cost, durability, and overall system design.


The solar industry is constantly growing and significant technological advancements are now a common occurrence. Not only is solar equipment becoming more powerful and efficient than ever before, prices are continuing to drop, which has helped contribute to the growing popularity of residential solar power systems.

We are often asked about the most powerful and highest wattage solar panels available, which is why we have decided to provide this straightforward explanation of what the highest wattage solar panels are today.

If you have questions about solar panel power and efficiency, you have come to the right place!

What are the Highest Wattage Solar Panels Available Today?

Currently, the highest wattage solar panels available to consumers are those with a power rating of 500 watts. While certain manufacturers are already developing the next generation of solar panels and there are rumours that panels with a rating of over 600 watts are on the horizon, it is difficult to find any solar panels that exceed 500 watts.

However, the problem with 500 watt solar panels is they are incredibly expensive. A limited number of manufacturers offer them, so this shortage of supply has naturally caused prices to skyrocket. Consumers always want to get their hands on the latest technology, so it is no surprise that the solar industry is also subject to supply and demand issues.

Do Not Get Drawn into Paying Inflated Prices

Despite the hype and increased demand for the most powerful solar panels available, it is worth noting that solar panels with power ratings of 400 watts to 450 watts are now common and relatively affordable. Just a few years ago, any solar panel that had a power rating of over 300 watts was considered the latest technology, so their prices were also sky high.

In other words, solar panels that are considered the most efficient and powerful today, will become significantly less expensive in the near future. The solar industry is advancing quickly, so it is easy to get sucked into paying outrageous prices for the latest equipment.

The truth is, you could purchase multiple lower-wattage solar panels for less money than a single 500 watt panel. The great thing about solar panels is you can easily chain them together to form a more powerful solar array. Rather than paying top dollar for a single solar panel that has a 500 watt power rating, you can save money by purchasing multiple lower-wattage solar panels that actually produce more power when they are linked together.

Consider High Wattage Solar Panel Kits

When it comes to maximizing the wattage of your solar panels, one of the best ways to get the most bang for your buck is to invest in a complete solar panel kit. Solar panel kits come with everything you need to start producing clean solar energy, which is incredibly convenient if you are just starting out.

Most kits will come with multiple solar panels, so they are capable of generating more solar energy that the latest and highest watt solar panels can on their own, but they are much more cost efficient.

Take, for example, our 1,200 Watt Monocrystalline Solar Panel Kit, which comes with everything you need to build your own off-grid solar power system. Rather than paying inflated prices for the latest 500 watt solar panels, this kit uses a series of highly efficient, black frame 300 watt monocrystalline solar panels. The three solar panels are easily linked together to generate an impressive 1,200 watts.

Not only can the four solar panels generate an impressive wattage when they are linked together, they are PERC cells, so they are much smaller and lighter than the more powerful and expensive 500 watt solar panels.

Not only do you get four highly efficient 300 watt solar panels that work incredibly well in low-light conditions, you also get a MidNight Classic MPPT charge controller, a MidNight Solar Combiner Box, a 15A-150 circuit breaker, and all of the solar cables you need to link everything together. In other words, you get everything you need to generate a significant amount of solar power in one convenient and affordable package, which is far more cost effective than buying the latest, high-wattage solar panels and building your own system from scratch.

which solar kit is right for you?

Beginner Solar Panel Kits

For those with lower power needs, or tighter budgets, beginner solar panel kits are a great way to get started with solar power, without committing to an expensive and complicated system.

The great thing about building a solar power system is you can always upgrade individual components or add more solar panels as your power requirements increase and your experience with solar power grows.

We specifically assembled our Lion Energy Beginner 400 Watt Solar Panel Kit so that those that are new to solar power could quickly start generating clean solar energy. This beginner solar kit is simply one of the quickest and most affordable ways you can get into solar power.

Not only does it come with a 100 watt foldable solar panel, you get a 400 watt power inverter, a Safari UT lithium solar battery in your choice of size, a Savanna 12V solar charge controller, and all of the cables you need to wire the kit together. 

If you want to expand the wattage of the kit, you can always choose to add one or more 100 Watt Solar Panels. These panels were designed to be long-lasting and feature completely sealed and waterproof designs, so you can leave them out in all weather conditions.

Buying Individual Solar Panels

If you already have a solar power system in place, you can always increase your system’s power rating by adding additional solar panels. As long as your charge controller, power inverter, and battery bank can support the additional wattage, you can easily add more panels into your system.

The particular type of solar panel you add is up to your own needs and the power capacity of your system. While you can certainly add one or more 100 watt solar panels, we often find that 200 watt solar panels find the perfect balance between performance and affordability.

100 watt solar panels

If you are looking to increase the overall wattage of your solar power system, take a look at our 200 Watt High Efficiency 12V Monocrystaline Solar Panel. They feature Mono PERC technology, which has an impressive efficiency rating of 19.98%. Their lightweight, anodized aluminium frames protect the solar cells, while an anti-reflective coated tempered glass cover ensures high sunlight transmission. The ‘plug and play’ junction box, included brackets, and pre-drilled mounting holes make it easy to incorporate these solar panels into any existing solar power system.

These 200 watt solar panels offer excellent value and are a great way to increase the wattage of your solar power system, without needing to blow your budget.

300 Watt Solar Panels

For those with greater power needs, 300 watt solar panels offer a great efficiency rating and power output, but they are significantly less expensive than the latest 500 watt panels.

Do Not Just Focus on Total Wattage

Far too many people get hung up on the wattage when shopping for solar panels. While having the latest and most efficient solar panels can be great, you will end up spending a significant amount of money to do so.

Rather than focus exclusively on finding the highest wattage solar panels, consider linking multiple solar panels together to generate a higher total wattage. There are even advantages to linking multiple solar panels together, rather than relying on a single high-wattage panel.

For starters, solar panels that are linked together can be positioned in different locations and on different angles, which will allow you to capture sunlight throughout the day, even as the position of the sun moves across the sky. Then, of course, multiple low-wattage panels are far more cost-effective than a single high-wattage panel.

Final Words

No matter what your power needs are, you should always consider, cost, build quality, durability, size, the type of solar cells used, and the overall weight of a solar panel. Rather than just focus on wattage, find solar panels that will actually last. You should also consider purchasing a solar panel kit, as bundling solar panels with other pieces of solar equipment will help cut down on prices. A good solar kit will also come with everything you need, so you will not have to worry about missing an important piece of equipment. 

We highly recommend reading through our How to Install Solar Panels Guide, which will tell you everything you need to know about getting your solar power system up and running. Remember, where and how you position your solar panels is almost more important than how powerful the solar panels are.
