Solestial: Funding, Investors & Team (Oct 2026)
Solestial, Inc. is a company that specializes in solar energy solutions for outer space. They have developed a new type of solar cell made from ultra-thin silicon that can repair radiation damage at normal temperatures in space. These cells are packaged into lightweight, flexible panels that can maintain their performance for up to 10 years in low Earth orbit (LEO). One major advantage of Solestial's technology is that it can be mass-produced using automated machines, resulting in costs that are 90% lower than existing solar technologies for space. Moreover, Solestial has the capacity to manufacture these panels in large quantities, meeting the demand for 100 MW of solar energy in space over the next 5 years. In contrast, current solar panels for space are prohibitively expensive and have slow manufacturing processes, taking over 10 years to produce 100 MW. By offering highly efficient and cost-effective space tolerant solar panels, Solestial is transforming the accessibility of power in space. Their lightweight and flexible design sets them apart from other products on the market. Solestial is leading the way in revolutionizing the space solar industry, and they welcome others to join them in this disruptive journey.
Solestial has raised $10.8M across 3 funding rounds on record, the most recent an undisclosed round of $850k announced in Nov 2023.
That round is below the $15M median round size for Energy companies tracked on FundedIQ over the last two years.

About FundedIQ's Solestial Funding Data
FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.
Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Solestial is left off this page rather than filled in.
