In the last ten years, solar energy has advanced significantly. The worldwide market was limited and heavily reliant on subsidy regimes in countries like Germany and Italy in 2010. 

Solar panels will be erected at a rate of more than 115 gigawatts (GW) this year, outnumbering all other generating methods combined. It's also getting cheaper, particularly in sunny areas, where it's currently the cheapest way to generate additional power.

Solar power currently provides around 3% of the world's electricity, and it's a massive, multinational sector with $141 billion spent in 2019. However, this falls well short of the projected $794 billion ($27 trillion by 2050) needed yearly for renewable energy to satisfy climate agreement goals and avert a global meltdown, according to the International Renewable Energy Agency.

Solar energy will become even more affordable in the future years as technology advances. Solar might become the most important source of energy for power production in much of the world by 2030. This will also help the ecology and reduce global warming.

The solar sector has very clear cost-cutting roadmaps in place for the future, with solar costs expected to halve by 2030. Larger modules that can generate 1.5 times more power than existing, similar size modules are already on the way, thanks to a process known as tandem silicon cells. These are going to have a big impact in the future.

Furthermore, there are technological improvements in the works that will lower the number of expensive materials needed in the construction of solar cells, such as silver and silicon, as well as bifacial modules, which allow panels to gather solar energy from both sides. 

The best way to incorporate solar into our homes, companies, and power infrastructures is another essential breakthrough. This means more low-cost digital technology and improved power electronics.

This means that solar will attain a Levelized cost of energy that will make it unmatched in comparison to fossil fuels in many places of the world. 

Given how simple and quick solar is to install, not to mention how versatile it is - after all, solar can power anything as little as a watch or as vast as a nation - solar installations should continue to rise in the future decade. This might also be beneficial to the environment.
