I was wondering if they create other forms of energy besides electrical that is unwanted. Like heat due to the friction of something, or sound. Also why is a solar panel not able to collect 00% of the energy that is striking its panels. And how could the efficiency of this be hypothetically improved.
Inability to generate electricity in the absence of light especially at nights or on a rainy day. secondly, it has an inability to store power.
Science. The best solar panels we have only get like 22% of the sunlight for conversion into energy. That is simply the best they know how to make with current technology. And for that your talking about a mobile panel that tracks the sun as it moves at the equator. A solar panel in say Canada is lucky to get 0% even on a sunny day. But even if a solar panel got 00% efficiency, it's still not a lot. Sunlight is too diffuse to be a good power source, and you'd need to cover lots of ground to get power. Worse, you can only get power when the sun is out during the day. So for power at night you'd need a battery, or another source of power. The 'newest' idea is to capture sunlight to make 'lasers' that boil water, to turn turbines and make electricity. They cost way more then they are worth right now though...
Solar panels produce very little heat or sound compared to electrical energy. In terms of the sunlight striking the panels, solar panels have an extremely poor efficiency because they can't possibly absorb 00% of the light energy. Solar panel efficiency is usually given is terms of converting the light that IS absorbed into electricity. Improvements are happening constantly. Mainly, trying to maximize electrical conductivity.
