History of Solar Generators & the EcoFlow Delta Pro

Technology has come a long way in recent years, and the push for clean energy is driving innovation like never before. 79% of Americans want to transition to entirely renewable energy, and one of the easiest ways to do that is by tossing out your old generator.

Well, solar generators, also known as portable power stations, have come a long way in recent years, overcoming odds and substantial obstacles. Let’s talk about the fascinating history of the EcoFlow Delta Pro and other solar generators on the market.

How Solar Generators Came to Be

Solar generators were made popular by a 2012 startup known as Jackery, which still sells popular solar generators today. These were supposed to be portable power stations designed for camping trips. Today, some solar generators can be used on job sites, in RVs, or even for home backup.

Of course, it wasn’t justportablepower stations. Some systems were designed to use solar panels on your rooftop for backup home power, like the Tesla Powerwall and other similar models that started making sales in April of 2015.

For portable power, Jackery was the first to create a large battery that you could charge in the car that couldalso use solar energy. Since then, several other companies have joined the mix, and they’ve come a long way. However, the best year for advancements was 2021, which we will talk about soon!

Challenges in the Market

Without a doubt, the biggest challenge in the solar generator market is competing with gas generators for output, lifespan, and price. Newer technologies are harder to optimize for low prices, so this is unsurprising. However, one company may have finally found the formula. Let’s talk about that!

EcoFlow Delta Pro History

Without a close second, the EcoFlow Delta Pro is the best solar generator on the market. You can read our full review of the Delta Pro for more information, but we can assure you that no other system lives up to its standards, and it has a fascinating history to back it up.

History of EcoFlow

Believe it or not, EcoFlow was established as recently as 2017 by a battery engineer named Lei Wang in China. Wang had previously worked for DJI making drones and launched his own projects using crowdfunding platforms like Kickstarter and Indiegogo. Since then, it’s become a serious topic of discussion in the world of tech!

Delta Pro Kickstarter

Other than its state-of-the-art features, the most impressive achievement of the Delta Pro was breaking Kickstarter’s all-time record for the most-funded project. Launched on July 15, 2021, the two-month campaign took off to raise over $12 million from 3,199 supporters, breaking the previous record by over $4 million. Not only that, but they raised their first $1 million within 10 minutes of launching the campaign.

The campaign received so many positive reactions from tech junkies, investors, and clean energy lovers due to EcoFlow’s promise of making a clean and portable power station that’s equipped for home backup. Well, they delivered!


Since its launch in 2021, the Delta Pro has become one of the most sought-after portable power stations on the market, but they’ve had one challenge. Their price tag has set them back on sales, but let’s do the math.

If you spend $3,500 on a Delta Pro that lasts for daily use, that breaks down to less than $1 a day of heavy use. Keep in mind that thefreeenergy you’ll receive from its advanced solar panels is worth more than $1 a day, but we’ll ignore that for now. Let’s compare that to another popular model.

If you buy a Jackery 1000 for $1,099 and it’s only geared for 600 lifecycles, that works out to $1.83 per day with a lot less energy output for each lifecycle. Yes, the Delta Pro costs more upfront, but there are payment plans that allow you to purchase the system for $100 a month, making it affordable to nearly anybody who wants it!

See for Yourself

Now that you know the history of the EcoFlow Delta Pro, you can see why it’s so popular. A lot of thought, time, and persistence went into crafting this device for consumers, and it truly is the only solar generator of its kind.
