KPRC 2 Investigates answer all of your questions about solar panels
Video Rating: / 5

The sun. One of the most powerful energy sources ever available to humans.
The process of exploration this energy began more than two thousand years ago, requiring at first colossal knowledge and skills from a person. Thanks to this labor, today, solar energy has become the cheapest in history. But why, with all its cheapness, is it not used so widely?

Perovskite solar cells are a remarkably cheap solar cell technology and have achieved remarkable growth since their inception a decade ago, sharply increasing in efficiency from 3.8% to 25.2%, near to their theoretical efficiency. Thus, the perovskite solar cell could be the future of solar energy. Perovskite solar cells are a new technology and still needs to be scaled up for commercial applications, but perovskites have the potential to revolutionise the energy harvesting market, with cheap, high efficiency solar energy in the near future. In this video, we’ll explore perovskite solar panels and how they might energize our future.

Let’s learn about solar energy basics! Watch this to know more about how solar power works. (Presented by AlliantEnergyKids.com)

When it comes to solar, Power (kW) and Energy (kWh) are two of the things I see people get mixed up the most – I’ve even seen trained solar salesmen confuse the two, especially when talking about batteries.

If you want to fundamentally understand solar power, batteries, electric cars, and the future of energy so you can reap the benefits of the technology instead of being bewildered by it all, then understanding the difference between power and energy is your first step.

In this video, I break down how the two relate to solar power and solar batteries in a simple, intuitive way.

If you know almost nothing about solar, consider this video your entry point :). You can also read about the difference between power and energy here: https://www.solarquotes.com.au/good-solar-guide/power-energy-difference/
