Solar panels

By definition any form of panel that engenders electricity by using solar energy is called a solar panel. There are different types of panels, some use solar energy to heat water and some deposit this energy into batteries to use it later on. In addition, a solar panel can be defined as a photovoltaic panel, which is used in the industry of professional solar energy to produce electricity from sunlight. No matter the kind of panel, almost all the solar panels are flat. The reason for this is that the most favourabel configuration requires an angle of 90 degrees to the sunlight.

Photovoltaic panels

These are the most common form of solar panels in the industry of power generation and are able to absorb the sun’s energy through a variety of small solar cells on the surface. Just like how a plant is capable of absorbing the sun’s energy for photosynthesis purposes, solar cells behave similarly. The energy is passed on to a silicon semiconductor as soon as the photons hit the solar cells. The photon is then turned into electricity and then passed through the connection of the wires to finally enter in an electricity facility or battery.

Future of solar panels

The current generation of solar panels are extremely inefficient and can not really convert more than 30% of sunlight into usable energy in the form of electricity. This problem is partly due to the materials used in the design of the solar panels and the size of the solar panel itself.

 Because of the relatively small range of wavelengths of light that can be exploited by solar panels, a large part of the energy that could be derived from sunlight is simply left to waste. In addition, if a photon of light hits the solar panel at too high of speed, energy is not transformed efficiently to electricity. This is even more of an issue when you use a DIY solar panel.

Modern materials and new techniques for the design of residential solar panel systems are on the horizon, but the promise of higher efficiency should still be delivered. The new silicon crystals that are less expensive to produce have thedownside of not being as effective as the original crystal silicon, but the panels are cheaper to produce allow either a similar or higher amount of electricity for the same investment.
