INTRODUCTION

In this summary, I will present a general overview of what solar power, panels is,  its pros and cons, effect and solution to the problems.

KEY TERMS
Solar power - solar power is produced by collecting sunlight and converting it into electricity. ( http://www.alternative-energy-news.info/technology/solar-power/)
Solar panels - Solar panels absorb the sunlight as a source of energy to generate electricity or heat. (https://en.wikipedia.org/wiki/Solar_panel)
Global warming - Global warming is the current increase in temperature of the Earth's surface (both land and water) as well as it's atmosphere. (https://whatsyourimpact.org/global-warming)
Power supply - A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the  load.(https://en.wikipedia.org/wiki/Power_supply)
Semiconductor - a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. It‘s used for making solar panels.
Manufacture - make something on a large scale using machinery.
Fundamental – the main (thing), a central importance.
Hurdle - a problem or difficulty that must be overcome.
Contamination - the action or state of making or being made impure by polluting or poisoning.


SUMMARY
Solar power is produced by collecting sunlight and converting it into electricity. This is done by using solar panels, which are large flat panels made up of many individual solar cells. It is most often used in remote locations, although it is becoming more popular in urban areas as well. Commercial concentrated solar power plants were first developed in the 1980s. Although, it‘s  mostly eco and nature-friendly it has some problems why it‘s not being so widely used. I‘m going to elaborate on its solutions to the problems , the positive and negative effect of it to humanity and  nature.
The sun offers the most abundant, reliable and pollution-free power in the world. However, problems with solar energy, namely the expensive cost and inconsistent availability, have prevented it from becoming a more utilized energy. Hampering solar power has a lot to do with cost. It is five to eleven times more expensive to produce electricity from the sun than it is from coal, hydro or nuclear sources. The first problem is with the cost of the technology: solar panels use expensive  material to generate electricity directly from sunlight. Semiconductor factories need 'clean' manufacturing environments and are expensive to build and maintain. But even if the fundamental cost hurdles of the technology are overcome, there are still other issues: installing solar panels on a house is expensive and requires experienced people. These systems used fixed solar panels since alignment systems are too expensive for the average homeowner . For example, giant solar farms have been built in desert regions and have reduced the installation cost since a larger economy-of-scale is created . But these large, inexpensive tracks of lands are found far from cities where the power is needed. Expensive transmission lines are needed to bring the power to a distant market.  Maintenance costs and time can add-up since every inch of a solar panel must be kept clean and clear of debris for them to operate at their most efficient. Their efficiency drops drastically even when a small portion is blocked by fallen debris or a film of dust. Producing Power During the  Day : Solar energy is only capable of producing power during the daytime (when the sun is out).
It is not only negative, it has a lot of pros as well. It‘s clean energy source and also Solar panels give off no contamination. The main contamination that occurs as a consequence of solar panels is the assembling of these gadgets in industrial facilities, the transportation of the merchandise, and the installation. It‘s also renewable and sustainable. Solar energy is a renewable source of energy which means we can not run out of it.
So, while solar is among the world's cleanest forms of energy, plans to develop utility scale solar farms have raised concerns about potential environmental impacts. That‘s why engineers need to develop more efficient production techniques. Mass production of panels in efficient factories will help bring down production costs and make them cheaper for costumers to buy.
