The Summer Solstice marks the first day of summer. This is the longest day of the year in the northern hemisphere.
Ever wondered why the days are longer in the summer and shorter in the winter? Or why we have seasons at all? We experience seasons because of the tilt of the earth as it circles the sun. The tilt also accounts for the change in sun hours throughout the year. As the earth tilts slightly towards the sun, our days get longer. Our peak tilt towards the sun in 2019 is June 21st!
How much energy does the sun produce?
At any moment, 173,000 terawatts (trillions of watts) of solar energy strikes the Earth. That’s more than 10,000 times the world’s total energy use. This summer solstice we’ll experience 15 hours of exposure to powerful & bountiful sun energy.
Why do we celebrate?
The Summer Solstice means that we are in peak summer production months for solar. This means that solar panels in the northern hemisphere have even more energy to soak up through the day.
Why celebrate in 2019?
In 2019 we‘re celebrating because there is more solar PV capacity worldwide than ever! This summer solstice the world has more solar infrastructure to soak up sunlight for use as energy than ever before!
According to the Solar Energy Industries Association (SEIA), as of 2019, the United States has 2 million solar installations- on homes, business, industrial buildings, and utility-scale solar installations. The energy generated by these solar systems combined would produce enough to power more than 12 million American homes. That is now greater than 70 gigawatts.
This reflects major growth in the solar sector in the U.S., which just 3 years ago reached 1 million solar installations. Additionally, the cumulative operating solar PV capacity is about 75 times more than what was installed at the end of 2008 (SEIA).
What has caused this growth?
The growth in the solar industry in recent years is a result of cumulative efforts by policymakers, solar customers, advocates, and business. The progress shows us the potential solar has to be a clean energy solution. Fueled by the incentive to create a better future for the planet, create jobs, reduce reliance on energy sources with harmful emissions and lower electric bills, we plan to see future growth in the solar market.
The Solar Energy Industries Association estimates that by 2024 2.5% of all US homes will have a home solar energy system installed. And we believe it. We are seeing solar become more and more mainstream. Between the federal Investment Tax Credit dropping to 26% at the end of 2019 (before it’s eventual drop to 0% in 2022) and the commercial tax credit eventually dropping to 10% for commercial projects, there are certainly incentives to go solar now.
