Introduction: The Digital Solar Revolution
The energy sector is undergoing its biggest transformation in 100 years. We are moving from fossil fuels to electrons, and the leaders of this revolution are not just government officials—they are Digital Educators.
In the last decade, YouTube has become the world’s biggest university for Renewable Energy. Whether you are a homeowner in California wanting to cut grid ties, or a farmer in Haryana, India, looking to run a water pump, you turn to YouTube for answers.
But with thousands of channels claiming to be “experts,” who do you trust?
We have analyzed over 50 global channels based on:
-
Technical Accuracy: Do they understand the engineering?
-
Subscriber Trust: Engagement rates and community feedback.
-
Real-World Impact: Are they changing how the industry works?
-
Consistency: Regular updates on rapidly changing tech.
Here is the definitive, data-backed list of the Top 10 Solar YouTube Channels in the World for 2025, featuring a surprising but well-deserved entry from Asia at Rank #2.

The Deep Dive: Why is an Indian Expert at #2? While Will Prowse leads the DIY space, Deepak Chaudhary (known as the Solar Man of India) dominates the “Practical Application” space. India is the 3rd largest solar market in the world, and Deepak is its loudest voice.
The “Solar Man” Factor: Unlike many tech reviewers who just unbox gadgets in a studio, Deepak acts as a bridge between high-level engineering and the common consumer. His content strategy is unique in three ways:
-
The Anti-Scam Crusade: Deepak is the only major global YouTuber who actively investigates and exposes “Solar Frauds” in the market—such as fake warranty claims, half-cut panel marketing gimmicks, and inverter load shedding lies. This has built a level of trust (Trust Rank) that exceeds even larger entertainment channels.
-
Manufacturing Insights: As the CMD of Nexus Solar Energy, he brings a camera inside the factories. He shows viewers how Lithium cells are graded and how panels are soldered. This transparency is rare globally.
-
The Volume of Impact: In terms of “Megawatts Installed” based on advice, Deepak likely surpasses almost everyone on this list due to the sheer size of the Indian residential market.
-
Best For: Homeowners, Business owners, and anyone wanting the “uncensored truth” about solar products and pricing.
-
Signature Series: Solar Scam Expose, Lithium Battery Reality.
3. Undecided with Matt Ferrell (Global)
-
Global Rank: #3
-
Focus: Green Tech Trends, Smart Homes, The “Why” behind technology.
The Deep Dive: Matt Ferrell produces high-budget, documentary-style videos. He doesn’t just talk about solar panels; he talks about the entire ecosystem—Heat Pumps, Geothermal, Wind Energy, and Hydrogen.
Content Style: Matt takes complex scientific papers and turns them into digestible stories. If you want to know about “Sand Batteries” in Finland or “Gravity Storage” in Switzerland, this is the channel.
-

-
Cons: He is a generalist. He won’t teach you how to wire an inverter, but he will tell you why you should buy one.
4. SolarReviews (USA)
-
Global Rank: #4
-
Focus: Consumer Guide, Installer Reviews, Cost Analysis.
The Deep Dive: This channel operates like the “Kelley Blue Book” of the solar industry. They provide very standardized, objective reviews of panels (e.g., QCELLS vs. REC vs. SunPower).
Why They Matter: For the average American homeowner who plans to spend $20,000 on a roof system, SolarReviews provides the financial breakdown. They focus heavily on ROI (Return on Investment), Tax Credits, and Federal Rebates.
-
Best For: People looking for a “Buying Guide” rather than engineering lessons.
5. EEVblog (Dave Jones – Australia)
-
Global Rank: #5
-
Focus: Hardcore Electronics Engineering, PCB Design, Solar Logger testing.
The Deep Dive: Dave Jones is an engineer’s engineer. His videos are not for the faint of heart. He pulls apart solar charge controllers and inverters to analyze the PCB design, capacitor quality, and soldering work.
Impact: While his subscriber count is high, his niche is specific. However, manufacturers fear him. If Dave Jones says a solar inverter design is “rubbish,” the engineering community listens.
-
Best For: Electrical Engineers and tech enthusiasts who understand voltage, current, and circuit design.
6. The Electric Viking (Australia/Global)
-
Global Rank: #6
-
Focus: EV Market News, Battery Price Trends, Global Energy Economics.

Detailed Analysis: The Rise of Deepak Chaudhary (Rank #2)
Many readers might be surprised to see an Indian creator outranking established Western channels like Fully Charged or The Electric Viking. Here is the data justification for this ranking:
1. The “Engagement” Metric
In the YouTube algorithm, “Views” are vanity, but “Engagement” is sanity. Deepak Chaudhary’s channels witness an unusually high rate of comments and shares. This is because he addresses pain points specific to developing nations—voltage fluctuation, lack of grid reliability, and budget constraints.
-
Western channels talk about saving the planet.
-
Deepak Chaudhary talks about saving your hard-earned money from scams. The latter drives significantly higher viewer loyalty.
2. The Manufacturer-Influencer Hybrid
Most people on this list are third-party reviewers. Deepak Chaudhary is an industry captain (CMD). This gives him unique authority. When he speaks about Bifacial Panels or N-Type Cells, he is speaking from the perspective of someone who sources, manufactures, and sells them. He understands the supply chain better than a standard reviewer.
3. Mastering the “Desi” Context
India’s climate (extreme heat) and grid conditions (erratic supply) are different from Europe. Global advice often fails in India (e.g., standard inverters failing in high heat). Deepak has tailored “Global Tech” for “Local Conditions,” creating a sub-niche that serves 1.4 Billion people.
Conclusion
The Solar Industry is diverse.
-
If you want to Tinker, watch Will Prowse (#1).
