A Century in Rewind: How Solar Panel Costs Have Plummeted

It's easy to look at solar energy today and see it as an obvious and natural outcome of technological advancement. Yet, the story of how it became an affordable option is one worth telling. Let's delve into its history, from its early days of high prices and inefficiency to its current wallet-friendly status.

Early Solar Adoption and High Costs

When PV modules first entered the market, they were prohibitively expensive. Back in the 1950s, the cost per watt of solar panels was around $300. At such a high price point, the use of photovoltaics was primarily limited to specialized fields like aerospace, where having a dependable, renewable energy source in harsh conditions was more important than the price. For most people, these early panels were more of a scientific curiosity than a viable option for home energy.

Midway Checkpoint: The Revolution Begins

Now, let's take a leap into the 1970s and 1980s, a period that marked the beginning of what we can call the solar revolution. It wasn't just technological advancements; there was a growing awareness among the general public regarding environmental issues like global warming. Coupled with the oil crises of the late 20th century, this led to increased interest in alternative energy sources. Solar energy, while still priced on the higher side but showing promise, began to receive more attention.

During this time, researchers and engineers were actively seeking ways to make solar more efficient. Silicon, the essential material for photovoltaic cells, became more affordable due to advances in extraction techniques. Slowly but surely, the price began to drop. However, it remained relatively high compared to fossil fuels, hovering at around $100 per watt by the end of the 1980s – a substantial amount, which, adjusted for inflation, would be over $370 today. Nevertheless, the stage was set, and the industry was filled with optimism.

21st Century: Where the Real Drop Happened

Fast forward to the new century, and we see the most dramatic shifts in solar affordability. According to a report by Otovo, the price of PV modules plummeted by approximately 90% from 2000 to 2021.  In the five years between 2015 and 2020, the prices dipped another 45%. As of 2023, the average price of solar has dropped to around $2.95 per watt —a stark contrast to the early 2000s.

Technological advancements played a colossal role. Solar panels have become more efficient, capable of converting a higher percentage of sunlight into electricity, making them more attractive. As demand increased, large-scale manufacturing became feasible, leading to solar prices dropping even more.

Additionally, global collaboration in the form of international agreements and trade policies fostered an environment where solar technology could flourish. Governments worldwide were now actively promoting solar adoption by providing subsidies and tax incentives, making it more appealing for both individuals and industries.

Huge solar farms became commonplace because of their viability. In the US, renewables now outcompete coal in terms of cost for 99% of the country’s coal-fired power plants.  Today, it's often more cost-effective to establish new solar energy facilities than to maintain existing coal plants. Moreover, businesses have embraced PV panels as part of their sustainability initiatives, and solar power has become an increasingly affordable choice for homeowners.

What Falling Prices Mean for Solar Adopters

If you've been hesitant about diving into the world of solar energy, the recent price decline should give you the nudge you need. PV panels are no longer an exclusive, high-cost game for eco-warriors. Today, solar is a smart, long-term investment for anyone who's interested. So, what does this price drop mean for you and other potential adopters? Let's get into it.

• Greater Accessibility: With solar prices dropping, photovoltaics became more attainable for a much broader audience. A middle-class family can now reasonably consider installing PV panels on their rooftop without breaking the bank. Additionally, some government programs provide extra help for low-income households. For instance, California's DAC-SASH program offers substantial subsidies for solar installations in low-income single-family homes—up to $3,000 per installed kilowatt.
• Increased ROI: In the past, you'd need ten or more years to recover the installation costs. Now, with solar prices dropping and more efficient technology, the payback period has considerably shortened. In just a few years, you could not only recover your costs but also earn some extra money if you sell surplus electricity back to the grid.
• More Innovation: Lower prices don't equate to lower quality. Quite the opposite— the solar industry is currently in a period of dynamic innovation. Companies are more motivated than ever to create efficient and flexible solutions, making it an exciting time to become a solar adopter.
• Energy Independence: Affordable solar energy is also a step toward energy independence. When more households and businesses make the switch, we decrease our reliance on traditional, often non-renewable, energy sources. This not only benefits individual consumers but also has important implications for national security and sustainability.
• Environmental Impact: Last but certainly not least, with the price of solar energy on the decline, it has become a practical alternative to fossil fuels on a larger scale. This leads to less pollution, fewer carbon emissions, and a smaller impact on the environment. Ultimately, the planet reaps the benefits, making each of us a shareholder in this global environmental victory.

Future Prospects for Solar Power Costs

Good news: solar energy is on a path to becoming even more affordable, shaking up the energy landscape like never before. The overall trend shows that solar energy prices are plummeting, and by 2025, it's expected to be cheaper than fossil fuels in most countries.  That's pretty astounding, but like any growing industry, there are challenges.

The COVID-19 pandemic caused problems in the supply chain, which in turn led to prices staying relatively stable. Even though they are predicted to go down by 2024, they'll likely still be 10-15% higher than they were before the pandemic.  

What's also interesting is the evolving landscape of solar costs. The hardware itself — think solar panels and other PV equipment — is becoming more affordable. But there's another side of the coin: soft costs, which include all the less tangible expenses like permitting, financing, and installation. They are making up a larger chunk of the total price tag. So, while the tech gets cheaper, the bureaucracy and logistics are still hurdles to jump.
