Hayes Barnard is an American billionaire entrepreneur. He is the founder, chairman, and CEO of GoodLeap, a sustainable energy financing company. Barnard is also the founder, chairman, and CEO of GivePower, a nonprofit that facilitates solar powered projects to provide clean water and energy systems to underserved communities.

In September 2003, Barnard founded Paramount Equity Mortgage (later renamed to Loanpal and subsequently rebranded to GoodLeap), one of the first to provide online residential home loans. In 2008, he founded Paramount Solar, a subsidiary of Paramount Equity Mortgage, and became CEO. In 2024, GoodLeap, announced that it had financed more than $20 billion in sustainable home-improvement loans, highlighting the company's ongoing growth in the clean-energy sector.

GivePower is a 501(c)(3) nonprofit organization that develops clean water and energy systems in underserved communities in developing countries. GivePower has developed water and energy systems in 17 countries, including communities in Africa, Asia, and Latin America. In 2018, Barnard's non-profit organization built a solar-powered desalination system in Kiunga, Kenya that produces 19,800 gallons of fresh drinking water a day. The organization also assisted the Sioux Nation in North Dakota in developing a 300-kilowatt solar farm in North Dakota, the first solar farm in the state. In 2016, Barnard left SolarCity and took on the role of chairman and CEO of Loanpal, a financial technology platform that provides financing for clean energy products. In 2020, Barnard started an asset management fund, GoodFinch. In 2021, Loanpal rebranded to GoodLeap, "good for life, earth and prosperity."

In May 2023, Barnard delivered the keynote address at the 140th commencement of the University of Texas at Austin.

Worked examples

Example 1 — a first encounter with Hayes Barnard

Start with the simplest possible case. Write down what Hayes Barnard claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hayes Barnard before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hayes Barnard ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hayes Barnard

In research: Hayes Barnard appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hayes Barnard in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hayes Barnard is common in secondary-school and first-year university syllabi. It links to neighbouring topics American chief executives of financial services companies, American company founders, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Hayes Barnard outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
