20 Interesting Facts about Solar Energy

Solar power is an abundant and free energy source that is created from a fusion of protons in hydrogen atoms that collide in the sun’s core and fuse to create helium, generating radiant heat and light.

Solar power has been used as early as the 7th century B.C. and was officially discovered in 1839 with the creation of modern silicon PV cells by Bell Labs.

The first silicon solar cell was built in 1954 by Bell Laboratories.

The space industry was an early adopter of solar technology in the 1950s.

Solar energy is the most abundant energy resource on earth, as 173,000 terawatts of solar energy strike the Earth continuously.

The California Mojave Desert hosts the world’s largest operating solar thermal energy plant.

Solar power is the most popular form of new electricity generation and is expected to account for almost half of new electricity generation in the U.S at least starting in 2022/2023 forward.

In the US, demand for solar power is at an all-time high, with installations increasing 23 times between 2008 and 2015 to an estimated 27.4 GW.

The cost of solar energy is continuously decreasing, making it increasingly economical for homeowners and businesses. Hence the global move for solar energy.

Solar power produces no pollution and drastically reduces the amount of fossil fuels used for power generation, improving global health and the environment. Hence solar termed as a clean energy source.

Solar panels installation can increase a home’s resale value. Check this article on how a solar installation can increase the value of a home.

Solar panels may help to lower electric bills.

Solar systems offer warranties, especially for solar panels range from 25 to 30 years.

The most efficient solar cells can convert 47.6% of sunlight into electricity. The National Renewable Energy Laboratory(NREL) maintains a chart of the highest confirmed conversion efficiencies for research cells for a range of photovoltaic technologies, plotted from 1976 to the present.

Solar energy can be used to power satellites, aircraft, and boats among other unique use cases.

The amount of solar energy that hits the Earth in one hour could meet the global energy needs for an entire year. This shows how powerful the sun is in terms of generating energy. If tapped well can be used as a primary source of energy globally.

Solar energy can be used to power desalination plants, making it possible to convert saltwater into drinking water. Solar desalination is a process that uses solar energy to remove salt and other minerals from saline water, making it safe for drinking or other purposes. It mimics the Earth’s natural water cycle and has been practiced by humans as a rudimentary method of water purification for centuries. There are two common methods of solar desalination – direct (thermal) and indirect (photovoltaic)

Solar power is being used to power large-scale infrastructure projects such as highways and airports.

Solar energy is being used to power remote areas where it is difficult to connect to the electrical grid. Perhaps the much hype on decentralized grids has been enabled mostly by solar energy. Thanks to solar energy.

In the US, solar industry was a major employer, with more than 230,000 solar workers in 2021.

Solar Panel Frequently Asked Questions(FAQs) – solar panel FAQs

Q: Can solar power save money? Yes, solar power can save money in the long run. By investing in solar power, you pre-pay your electricity costs upfront, which can result in significant savings over time.

Q: Will the cost of solar power decrease in the future? Although the cost of solar power has decreased over time, experts predict that prices may increase in the coming years due to increased demand and a trade dispute that could result in tariffs on imported solar panels.

Q: What are the financial benefits of solar energy? The financial benefits of solar energy include significant cost savings on electricity bills, increased property values, and tax incentives.

Q: What are the environmental benefits of solar energy? Solar energy is a clean and renewable energy source that produces no greenhouse gas emissions and reduces dependence on fossil fuels. It also helps to conserve water resources and protect natural habitats.

Q: How does solar power work? Solar power works by converting sunlight into electricity using photovoltaic cells. The panels collect sunlight, which is then converted into direct current (DC) electricity. An inverter then converts the DC electricity into alternating current (AC) electricity, which can be used to power homes and businesses.

Q: How long do solar panels last? Solar panels typically have a lifespan of 25-30 years, although some panels can last up to 40 years with proper maintenance.

Q: Is solar power reliable? Yes, solar power is a reliable source of energy, as long as there is sufficient sunlight available. In areas with low sunlight, solar power may be less reliable and may require a backup power source.

Q: Why is solar power not widely used? Solar power is not yet widely used due to several factors, including high upfront costs, limited availability in certain areas, and lack of awareness about its benefits. However, as the cost of solar power continues to decrease and technology improves, more people are expected to adopt this clean energy source.

Q: Why is solar power useful? Solar power is useful because it is a clean and renewable energy source that can help reduce dependence on fossil fuels and lower greenhouse gas emissions. It can also provide significant cost savings on electricity bills and increase property values.

Q: Are solar power systems really worth it? Yes, solar power systems are worth it for many homeowners and businesses. While the upfront costs can be high, the long-term financial and environmental benefits can be significant. Additionally, tax incentives and financing options can make solar power more accessible and affordable for many people.
