The debate over whether or not to invest heavily in renewable energy remains a hot topic. However, energy technologies are outpacing governments worldwide, and this discussion could soon become obsolete.
One of the biggest barriers for some renewable energies, such as solar, has been the high initial investment cost. However, according to a report by GTM Research, the prices of solar installations will continue to fall, reaching up to 27% by 2022. The trend predicts an average reduction of 4.4% per year until that percentage is achieved.
Solar energy prices drop
The GTM Research report offers a clear forecast on the prices of photovoltaic solar systems. It details a continued downward trend in the cost of solar projects , including reductions in the price of modules, inverters, solar trackers, and labor. This trend will not only lower costs but also make renewable energy more accessible to different regions.
A prominent example is India, where the government auction system has created a highly competitive environment that has enabled record-low bid prices. Many other regions will continue to benefit from these falling prices, bringing more consumers closer to clean energy, especially emerging countries that urgently need more sustainable energy solutions.
This scenario raises the question of whether solar energy will be a key driver in the transition to a cleaner global energy system . While lower prices are a significant step, they are not enough to guarantee widespread adoption. Solar energy must become more competitive in the short term to become firmly established.
It is already the cheapest source of energy in more than 50 countries, but to be globally efficient it needs to continue reducing its price per megawatt/hour compared to other conventional sources.
The battle for energy: a long-term vision
When analysing the evolution of the energy market, it is important to bear in mind that energy systems require investment plans decades in advance. This is due to the large investment required for infrastructures such as nuclear or gas power plants, whose dismantling before the end of their useful life is not economically viable.
This long-term planning model can slow the adoption of renewable energy , since once energy infrastructure is built, it must continue operating until the investment is recouped. Solar energy faces the need to demonstrate profitability in the short and medium term to ensure its widespread adoption in the coming years.
Solar energy can compete with other sources
Reports indicate that unsubsidized solar energy is beginning to displace coal and natural gas in many emerging markets . In fact, new solar developments in markets such as India, Chile, and Mexico are starting to prove cheaper than wind energy projects in many areas.
In 2022, more than 60 countries saw a drop in the price of the solar installations needed to produce each megawatt, reaching approximately $1.650.000, below the $1.660.000 cost of wind power . This slight difference highlights how the competitiveness of solar energy is growing by leaps and bounds , even compared to other renewable energy sources.
This puts solar energy in a favourable position to lead the change towards a cleaner energy system, especially in emerging countries, which contribute greatly to the increase in CO2 emissions.
The cost of solar energy versus coal
In recent years, several energy auctions have set new records for the price of solar power . For example, in August a contract was signed in Chile to generate electricity at $29 per megawatt-hour , almost half the cost of coal.
This demonstrates not only technological advancements but also the growing interest in long-term contracts that allow companies to benefit from the lower costs of solar energy . This is crucial for competing with fossil fuels on a large scale.
The Levelized Costs Of Energy report shows that renewable energy has continued to significantly reduce its costs, while conventional energy faces price increases due to rising raw material and fossil fuel costs.
Solar energy and long-term cost reduction
Solar energy has proven to be a profitable long-term investment, not only due to the constant reduction in installation costs but also because of its predictable prices compared to other volatile technologies such as gas or coal. In the last five years, the cost of solar energy has fallen by more than 60% , and this trend is expected to continue as more countries adopt policies that promote clean energy.
One of the key factors driving this reduction is improved efficiency of solar panels and increased standardisation in manufacturing processes. Installing solar panels is now easier and cheaper than ever, and more applications are being discovered all the time, helping to maintain this trend.
Self-consumption and advantages of solar energy
Self -consumption is one of the most attractive alternatives for those looking to reduce their dependence on the electricity grid and significantly lower their energy costs. By installing solar panels on the roofs of homes or buildings, both households and businesses can generate their own energy and reduce their electricity bills by between 50% and 95%.
There are two main types of self-consumption:
- Self-consumption without surpluses: All the energy generated by the installation is used and part of it is stored in batteries to avoid dependence on the electrical grid during times of low solar generation.
- Self-consumption with surpluses: Energy not used for personal consumption is fed back into the grid, and financial compensation is received for this.
Thanks to these options, many companies are migrating towards a self-consumption model that allows them to save significantly on their operating costs and contribute to sustainability.
As prices continue to fall and technology advances, solar energy will become the most cost-effective solution for the energy future, not only for self-consumption but globally.
