Currently, 50% of Germany’s net electricity is generated from solar energy. Harnessing solar energy to generate electricity is becoming more mainstream as the world moves towards a green future. The International Energy Agency projects that Solar Photo-Voltaic would be the most installed power generation capacity by source by 2040. Solar is slowly being adopted around the world, due to its zero emissions of harmful substances during operation. It is necessary to examine how solar energy is harnessed and the current efficiencies.

Solar energy refers to energy harnessed from the sun. The sun gives off light and heat and these can be harnessed for different activities i.e. the light or heat from the sun can be harnessed for power. Solar energy has been harnessed since 7th Century B.C. where magnifying glasses were first used to concentrate the sun’s rays to make fire (and burn ants). As time passed, the technology improved with Roman bathhouses constructed to have large south facing windows which let the sun’s warmth into the designated area, between the
1st to 4th Century A.D. There have been a large number of historical inventions and innovations aimed at harnessing the sun’s energy to meet human needs, and there will be more of such.

This article will focus on solar energy harnessed to cook food and to produce electricity. The solar collector was invented in 1767, which was later used to cook food in the 1830s. This was relatively earlier than the discovery of the photovoltaic effect in 1839. These technologies have greatly improved in the last century and this article shall examine their operations.

Solar Energy for Producing Electricity

How the Photovoltaic Cell Works
Solar photovoltaic conversion is the conversion of sunlight into electricity. Photovoltaic (PV) cells react to light by turning part of it into electricity. Silicon is the most used PV cell material, for this reason a lot of research has gone into silicon as a way of understanding PV cells. When light strikes a silicon crystal, it is either reflected, absorbed or goes right through the crystal. Absorbed light (of great energy) upon striking the silicon crystal causes electrons to separate from their bonds. These free electrons are the means by which electricity flows. The electrons are acted upon by a (built-in) potential barrier which causes the electrons to produce a voltage used to drive a current through the circuit. The potential barrier can be created by doping the PV material, i.e. adding an impurity in order to aid electron movement. In 1960, solar cells were 5% efficient, but recent solar cells are 24% efficient, although the majority of solar panels are below 20% efficient.

Photovoltaic System Set-up
There are certain considerations necessary to effectively install a PV system. PV modules (collection of solar cells) need to be mounted where there is direct access to sunlight. PV modules are usually mounted on roofs but can be mounted on the ground as well. It is also necessary to ensure that there is no shading around as even the shadow of a single branch of a
leafless tree can significantly reduce the power output of a solar module. PV modules are conventionally oriented towards the true south but would also work fine (with less efficiency) if on a roof facing east or west. Solar modules (specifically stationary modules) also have to be tilted plus or minus 15° with respect to that location’s geographic latitude, based on the time of the year.
The flow of energy in a stand-alone Photovoltaic system goes thus:
1. Solar Modules (Panel): here, the light rays are converted to electricity.
2. Charge Controller: also referred to as battery charger. Its primary function is the prevention of the overcharging of batteries, which eventually damages them. It regulates the power going into the battery from the solar panels and cuts off excess power. It is necessary for off-grid solar PV systems; in grid-connected systems, excess power goes into the grid.
3. Battery: batteries store direct current (DC) energy for later use. The batteries store energy for use after the solar panels are not receiving sunlight. Types of batteries include Lithium-ion batteries and Lead Acid batteries.
4. Inverter: the inverter converts DC to Alternating Current (AC). The AC is used to run appliances in the building.

I tap from you too Hush

My dear drinking gutter water tells you the kind of shit the country is in now literally. I don't know if you have heard " Next level"

Great country in poor evil hands of people called leaders

Jesu! Cow hybrid. Deficiency of staying indoors, been close to cows and eating excessive cow meat during pregnancy

enemyofprogress:
experience is talking. Wehdone ma!

Most Thoughtful post of this election season.

�Saraki and his wife cast their votes in their polling unit,
Buhari and his wife cast their votes,
Atiku and his wife cast their votes,
Peter Obi and his wife cast their votes, Osibanjo and his wife cast their votes,
Wike and his wife cast their votes,
Amaechi and his wife cast their votes.......
all of them and their wives voted in their polling units according to news and with what we saw on television and were escorted to the polling units by their bodyguards and security men BUT NON OF THEM WENT WITH THEIR CHILDREN.
�Does it mean non of these people have children that are up to 18yrs that can vote? Or they went to another polling unit to vote or they came with their parents and the camera didn't catch them?

Their children are all in safe locations or over seas for security reasons

Fake dollar and stollen money it's always news we hear but we don't get to see this money. Did it disappear or fly into the country? This was done by government officials with high clearance and security. When money is not equally shared it is missing in news, when it is not shared it is embezzled, when it is equally shared it is no news. When economy change it is subsidy removal now it is economic recession next will be what??

People should know it's not about showing "Ole" verbally when your vote can do better. Let's put hands together to do the right thing and avoid been bought!

What do you expect a lion in Sheep clothing, when a poor minded military man holds power instead of being with his animals in the bush

They will soon arrest all the toads in Atiku's drainage then there be nothing again and they will start arresting their masters then themselves. End of story

M. O. G, are you sure saying four or five years of term in office, standing on Nigerian soil I believe it's 9 years long term imprisonment you are seeing for Buhari. Maybe it's not clear to you! See again

Hahaha! Na wah oh kaikai dey work oh who anoint Buhari? So u leave weytin u suppose see dey see upside down? Don't worry Buhari will rule your country and will be your member. So all the evil wey dey happen for your own country no dey important for you to see abi Na Nigeria own u go see!

manalejo:
I need that kind of a lady. Can you hook me up with her?

Don't fall in love with pictures you see on social media, body odour, mouth odour and bad character don't show online

Weytin dey d shoe? This one sef Na news wey we go read?

Ok! Since Na by her power make she bring the whole marriage money come Na or better still make she marry you. She think say Na so e easy for us wey afta marriage them go dey tweak on social media, saying "happily marriage" who say Na happily married with dry pocket for where? Ok, mak we dey sure what if u marry finish dia dey s...., e don scatter or it has been over drilled without any oil left for u to enjoy? When dem don dey run oil of age with new age declaration dem go dey worry person wit lots of conditions without patience.

Is it not better? What if she took you to San baba for corruption alligation. You find help or work you get now you dey complain, you no tell us how u take worry her from the start oh n u won't tell me that you have never known what your friend was into.

This is politics things are played differently not regarding moral, Christ or peace and love.

Death sentence sharp sharp

Make them(police) eat am or better still make e smell there, since the police loves money move than lives

5 - 4 football scores. Nigeria

5-4 football scores Nigeria

When him money finish she go leave am go marry another man, which girl wan suffer or work? Most girls Na so so free things them like and make man dey spend on them as if them be investment wey dey pay but they are just liability to men and their business plans. No reasonable woman or lady that want your success would intentionally want you to spend so much on her, except for few celebrities for fame sake. But now even girls wey no sabi brush mouth sef want make man spend everything on her so she will look good, to run away easily.

There is a very big difference between a cow of burden with a cow and a castrated cow, imagine a money leading hens.

When a crowless chicken is ruling Nigeria, now it's time to lead us to survival camp

As for now all the corruption fighters and their family will join the poverty now

Movies, walking dead season 1, Episode 1, fear. Why won't the old campaign for themselves

Me I just need only 50k to support my business oh but no financial institution wan help with loan or grant!

There is difference between boyfriend and son! Which one is he? Or is he about to be converted to bobrisky or turning him on? Child abuse, thank God it's your child your training to be a rapist or womanizer may be one day he'll have erection.

Nonsense!, I wife can't do this on social media

To love no be by muscle or beauty, if it's hard for you to express it for her then that means the two of you can't have a future together, why not let her go? Because you two are incomparable

Na ur time
