Solar energy is emerging as one of the best renewable alternatives to our diminishing gas, coal, and oil supplies. We must reduce our dependence on fossil fuels that emit greenhouses gases, and are the major contributors to global warming and climate change.
The general trend of increased solar installations and reduced costs will continue, with most countries in the world contributing to the production of solar energy in some way, however small.
It’s been estimated that the earth receives more than 173,000 terawatts of energy from the sun each year, which is about 10,000 times more than the entire planet can use, so there’s no concerns about running out of solar power.
The cost of photovoltaic modules is now about 200 times less in real terms than the cost in 1978, and it’s not just PV modules that are much cheaper. All components in the system are coming down in price due to increased demand and new technology that enables cheaper production.
With our increasing awareness of the need for more sustainable energy sources, the low cost of solar energy systems is one of the main reasons the industry has grown so much, as more people and businesses are adopting solar technology.
Battery Storage and Off-Grid Solutions
Out of the new solar technology in recent years have come more efficient and cheaper batteries for storing excess solar power. With battery storage, people can use only their own solar power and will no longer need to connect to the main grid in case they run out of electricity. Solar power stations are also taking advantage of new technology in battery storage to deliver more sustainable power solutions.
The Tesla Powerwall is a great example of new technology in battery storage. It’s sleek and efficient, and you can use up to ten at a time for increased storage. Another example is the Tesla Powerpack for larger commercial applications.
Silicon photovoltaic modules are the dominant solar technology, and are likely to be for at least the next ten years. However, a new type of solar cell technology has emerged. Metal halide perovskites are still in the testing phase but have the potential to be cheaper and more efficient than PV cells. Currently, scientists are finding success by piggy-backing metal halide perovskites on existing PV cells (perovskite-silicon tandems) to increase performance and output.
