The Vast Potential of Solar Energy

For the average American a residential solar system is the most recognizable symbol of the broader solar industry. Without a doubt, the rise of the modern solar photovoltaic installer is key to the widespread adoption of renewable energy over conventional fossil fuels. Like other industries, the solar market has evolved dramatically due to the commitment of governments and investments by large corporations and private developers.

The rapid growth in renewable energy capacity globally and within the United States is redefining the present and future of solar photovoltaics and how the electricity generated impacts the environment.

What can solar energy statistics reveal about the past decade and the future of the solar industry?

First and foremost, to say that most solar energy is a gross understatement:

So why has natural gas, coal, and other energy sources eclipsed solar electricity generation for so long?

U.S. Grid 99.95%
U.S. grid boasts a 99.95% relatability rate.
Lower Costs 70%
The costs of solar have fallen by 70% since 2010.

The Solar Revolution: Costs Plummet and Capacity Rises Since 2010

The scope of solar energy’s potential is staggering, but harnessing, storing, and utilizing most solar energy has remained elusive.

Despite its abundant availability, a vast majority of this solar potential remains untapped. Until recently, the full realization of solar electricity generation has been limited by several factors.

At least in the United States, the grid built on other traditional fossil fuels has been stable without solar:

  • #2: The U.S. grid boasts a 99.95% relatability rate. Per the National Renewable Energy Laboratory, on average customers experience fewer than two outages per year, totaling under five hours of downtime. (National Renewable Energy Laboratory (NREL))

The lack of demand relegated most solar panels to a niche market. More importantly, the costs of solar photovoltaics were exceptionally higher than other resources. In the 2010s, a dramatic shift in the solar market occurred:

  • #3: The costs of solar have fallen by 70% since 2010. A $40,000 residential system of solar panels installed in 2010 now costs around $18,000.

Combined with the global shift towards renewable energy sources, solar power stands out as a key player, promising to revolutionize how we generate and consume electricity. Over the past two decades, continuous advancements in solar technology and decreasing costs have made solar energy more accessible than ever.

To meet the demand and achieve a long-term vision of utility-scale solar, there remain further achievements and breakthroughs in the design of solar photovoltaics, manufacturing capacity, solar PV capacity, grid integration, and other challenges to solar industry growth.

The Untapped Energy of the Sun

While the solar capacity installed in the last two decades has reshaped the industry, the sun’s energy is colossal. Only a fraction of the solar energy that reaches the Earth is currently harnessed for electricity generation.

This untapped potential represents an incredible opportunity for growth in the solar sector. The challenge lies not in the availability of solar energy but in harnessing it more effectively and efficiently. With continuous technological advancements and increasing global awareness, the potential for solar energy to meet a substantial portion of our energy needs is more feasible than ever.

  • #6: According to the Energy Information Administration, the electricity generated by a PV solar system can produce enough energy to offset the energy used for its manufacture in as little as 1 to 4 years. (EIA)
  • #7: The EIA also notes that most solar PV systems operate for 30 years or more.

For both residential and commercial use, solar has become a more widely accepted source of clean energy. Solar panels installed for homes, businesses, and corporate headquarters are likely to become more normal shortly.

Renewable capacity additions and utility-scale solar are rising exponentially within the US as well. The potential of solar power is vast and largely untapped, and solar continues to offer a beacon of hope for a cleaner, more sustainable future. This exploration sheds light on the significant role solar energy plays in reshaping our energy landscape.

  • #8: As per the Energy Information Administration, there are plans by developers and power plant owners to greatly boost utility-scale battery storage in the United States from under 10.0 gigawatts in 2022 to reach 30.0 gigawatts by the end of 2025. (EIA)

The potential for solar photovoltaics is not simply the electricity generated by more sophisticated systems. Just like wind turbines, how much energy that can be stored is key to the viability of renewable energy.

Advances in solar PV capacity are crucial to meeting the vision of the solar industry.

  • #9: By 2032, projections from the National Renewable Energy Laboratory’s Standard Scenarios, which include anticipated increases in capacity and generation, estimate that wind and solar will contribute around 47% of the nation’s electricity. (NREL)

Let’s examine in detail the current state of solar energy in the U.S. and how the solar industry can become a cornerstone of the electricity grid.
