When you think of Tesla, you probably imagine sleek electric cars and maybe even a futuristic Cybertruck. But Tesla is also a major player in the world of solar energy. One question people often ask is: “Does Tesla really make its own solar panels?” The answer isn’t a simple yes or no. In this article, we break down what Tesla actually uses for its solar products, how their technology works, and what that means for homeowners, businesses, and energy professionals.

Tesla and Solar Energy
Tesla entered the solar market in 2016 by acquiring SolarCity, a company co-founded by Elon Musk’s cousins. This move helped Tesla expand its clean energy vision beyond just electric vehicles. Today, Tesla offers two main solar products:
- Tesla Solar Panels: Standard panels installed on rooftops.
- Tesla Solar Roof: Innovative tiles that look like roofing materials but double as solar cells.
Tesla also bundles these products with Powerwall, a home battery system that stores solar energy for nighttime use or power outages.
Does Tesla Actually Make Its Own Solar Panels?
The Short Answer: Not Entirely
Tesla does not manufacture all its own solar panels. While the company produces some unique products like the Solar Roof at Gigafactory 2 in Buffalo, New York, it also sources traditional solar panels from third-party manufacturers, especially for its standard rooftop installations.
One of Tesla’s main suppliers is Hanwha Q Cells, a leading solar panel manufacturer based in South Korea. This partnership allows Tesla to maintain quality without having to produce every component in-house.
What About the Tesla Solar Roof?
This is where Tesla truly stands out. The Solar Roof is manufactured by Tesla, designed in-house, and represents an innovation in solar tech. Unlike traditional panels, these tiles replace your existing roof and function as both roofing material and energy generators.
What Types of Solar Panels Does Tesla Use?
Standard Panels
Tesla’s standard solar panels are monocrystalline, known for their efficiency and aesthetic appeal. They typically have an efficiency rating of 19% to 20%, which is comparable to other major brands like SunPower and LG.
Tesla does not disclose the exact model or manufacturer of every panel they use, but reports and user reviews consistently mention high-quality panels with reliable performance.
Solar Roof Tiles
Tesla’s Solar Roof tiles are designed and manufactured in the U.S., offering:
- Sleek, low-profile design
- Durability to withstand weather and wear
- 25-year warranty
- Integrated Powerwall compatibility
- Custom design to match various roofing styles

Tesla’s Energy Ecosystem
One of the key advantages Tesla offers is an all-in-one energy solution. Tesla’s solar panels and roofs integrate with:
- Powerwall: Stores solar energy for use at night or during outages
- Tesla Energy App: Allows users to track production, usage, and storage in real-time
- EV charging: Helps power Tesla vehicles with solar energy
This seamless system offers greater control, convenience, and energy independence.
Why Tesla Outsources Its Panels
Manufacturing solar panels is capital-intensive. By outsourcing traditional solar modules, Tesla can focus on innovation, like the Solar Roof, and battery storage. Working with experienced panel manufacturers like Hanwha Q Cells allows Tesla to ensure quality while optimizing production.
