Solar power is still the world’s most untapped resource. Most of the planet gets a reasonable number of hours of sunlight every year, and yet we still have an energy crisis. We can’t ignore any longer the negative effects of our use and abuse of fossil fuels for centuries.
But there’s good news:
In the name of energy security and climate change mitigation, the sun (as a power source) is finally getting the attention and investment it deserves.
With that in mind:
Let’s dig into the most relevant solar energy statistics and facts available to see how far along we are in our quest for sustainability.
To put things into perspective, all humans on the planet consume 410 quintillion Joules of energy every year. In other words, we receive considerably more clean energy from our nearest star in over 60 minutes than we can use in 365 days. These basic solar energy facts should refute any doubt about the sun’s potential to power our rapidly growing industries.

Strictly speaking, this giant ball of fire will go out someday. But its longevity is irrelevant to us, as our very existence as a species could be decided in the next 100 years.
These quick facts about solar energy tell us that the sun is ages away from being on its last legs. It is sustainable enough to buy us time to figure out the most efficient methods and develop the most effective machines to optimize its power.

Asimov’s brainchild is certainly one of the cool facts about solar energy in pop culture. Although the NASA abandoned the idea decades ago, the China Academy of Space Technology plans to adopt it and build a solar station in space by 2035.

Researchers at the Oregon State University discovered that croplands offer optimum conditions for solar energy generation using PV panels. Called agrivoltaics, the idea of fusing agriculture and PV power production is one of the newest solar energy fun facts we should all be excited about.
For instance, Mumbai, the world’s most densely populated metropolis, has to allot 3.2% of its territory to lay down 19 kilometers of solar panels in order to satisfy the electricity consumption needs of its over 14.3 million inhabitants without emitting greenhouse gases.

It is one of those random facts about solar energy that could give environment-conscious Americans hope, but it is far from feasible. Cost, safety, durability, efficiency, and reliability are some of the unaddressed concerns that plague the widespread construction of solar roadways in the US.
This natural phenomenon happens because the Earth tilts 23° on its axis. Sure, the rest of the year would mean no sunlight at all. But the ready availability of months worth of uninterrupted sunshine at the North Pole is one of the most underappreciated solar power and sustainable energy facts out there.

The current solar and wind energy statistics and liberal generation projections of renewables pale in comparison with the overall energy coming from the sun scattered in space. One estimation explains that our planet catches just a small part of the star’s 2.3 billion solar power output.
These facts about the sun and solar energy would be the answer to many of the world’s most pressing industrial and environmental problems only if we could master the collection, electricity conversion, and distribution of space solar power.

Roadways is perhaps one of the solar energy source facts that should have never been. Seen as a road to nowhere right from the get-go, the Wattway was built in 2016 despite the better judgment of experts.
It never achieved its power generation target of 790 kWh per day throughout its history. The Wattway’s most productive year was its maiden one when its solar energy facts and statistics translated to 409 kWh of green electricity per day.
Its performance declined as its condition deteriorated due to excessive vehicle weight, unstoppable weather damage, and disappointing design failure, managing to produce just 200 kWh per day last year.

The fast-growing South Asian economy is running out of time to tally better solar energy information and facts. By the end of March 2019, there was just 4,375 megawatts of rooftop solar PV panel systems installed. It’s a far cry from its double-digit goal.

The facts about solar energy and its pros and cons change as the renewable’s adoption rate goes up. However, the truth remains that we still can’t manufacture PV panels without polluting the atmosphere with greenhouse gases.
Although such emissions can be trapped in production facilities, any large-scale breaches could change the narrative regarding the good facts about solar energy.
The refinement process to create poly-silicon, an essential in the manufacture of solar panels, leads to the creation of large amounts of SiCl4, which can be a terrible hazard when it comes in contact with H2O.
The unintended production of this inorganic compound alone will not ruin the healthy balance between positive and negative facts about solar energy generation. After all, SiCl4 can be made into more poly-silicon. Sadly, most manufacturing facilities lack the equipment needed to recycle this byproduct due to high cost.
Compared to traditional units, one of the positive facts about solar energy generated by thin-film panels is less emission. However, their production has resulted in high metal depletion of CIGS, which will worsen with poor end-of-life recovery.

Recycling stats suggest that low recyclability is one of the notable negative facts about solar energy generation. Such a small number will not make solar panel recycling lucrative enough to become its own industry, let alone thrive.
So far, solar is not a realistic source of baseload power for massive economies such as the US and China. That is one of the main reasons why only small countries like Costa Rica have been able to run exclusively renewable energy for a long period.

These solar panels stats parallel the longevity of asphalt shingles. Such figures do not mean that these electricity-producing units become useless after three decades, though. It is just that the solar power output of contemporary PV panels can significantly drop after that period.

After year 25, the typical solar panel will operate at just 82.5%. In comparison, a premium unit can produce about 87.5% of the amount of electricity it used to generate when it was first installed. These solar energy stats are expected to improve in the years ahead with the advent of next-gen tech, but they hardly make contemporary PV panels more marketable.
Time has a way of dramatically changing solar energy facts and blurring this renewable’s pros and cons. Once considered a drawback, price has been instrumental in making many solar projects more economically viable.

Based on the latest solar energy vs. wind energy facts, the difference in capacity between the two renewables remains wide, though. By the end of that year, wind energy had 564 GW, while solar recorded 480 GW. However, neither of them could catch hydropower anytime soon with 1,172 gigawatts.

This is one of those facts about solar energy in America that involves a gray area.

In 2019, the country’s PV power installation capacity was estimated to jump by 14%, sustaining the upward trajectory of certain solar energy statistics of the United States.
Compared to the valuation in 2015 (the year when energy storage truly began making inroads), the number translates to 243% growth.
This suggests the solar energy usage in the US is becoming more efficient. More and more homeowners, as well as grid managers and utilities, are able to handle the flow of electricity from renewables without causing an imbalance between the demand and supply of power.
