Are you boggling with a question like: how do solar panels work?
and what makes up a solar panel?
Some few years ago as I walk through the high streets, I saw a lot of solar panels on people’s roof.
Others mounted it on the entire roof and others on halfway.
What does it do?
Is it a new type of roof?
In fact, let’s call a spade a spade.
I knew nothing about solar panels and how they work until a friend told me it generates electric power to be used in homes.
I was in ultimate shock to know how such a thing could produce power and wanted to know more.
After years of installing panels myself and working with solar panels, I thought I should produce a piece on how solar panels work.
If you are thinking of getting solar panels and what comes in your head is how solar panels work, I‘ve got you covered.
I understand you’ve heard a lot of jargons about solar panels and how they generate electricity.
Or how solar panels produce power to be sold to electric companies.
In this article, I wish to break in simple terms how solar panels work.
What you will learn in these posts.
Without having cheaper gas energy in your home you may be forced to use more electric power.
This can be an expensive choice even if you use the very best and
most efficient electric powered heaters and water systems.
So you may have considered adding solar panels to your home in a bid
to save money on your electricity bills and maybe even make an income from the excess power produced.
Knowing exactly how solar panels work will help you decide if installing them is the best thing to do for your home.
Information is power and here it is literally the case.
It was discovered in 1839 by a scientist that it was possible to convert the energy from the sun into electricity.
However, the idea didn’t catch on until the 60’s when solar panels were first used on spacecraft.
Yet where might we be without developments? All things considered, the appropriate response is genuinely simple to deduce; lounging around in our mud hovels trusting the cow will create some drain, and that our vegetables will develop.
Innovations have given people the edge over alternate species on the planet, as our cooperative personalities make another world greater and superior to the one preceding.
The issue is, people are error-prone – and what’s increasing, pompous.
People have, consistently, had an uncanny capacity to concoct things that will enhance our lives always – yet we’re similarly prone to gloat about our disclosures, as well.
This craving to demonstrate the world what we have revealed and exactly how extremely smart we are has prompted numerous great innovations being attempted before they were prepared; they consequently failed, and the thought was pushed to the back of a cabinet,
expelled from history for eternity.
The innovations that have endured have done as such for one of two reasons: right off the bat, the designer was wise enough to perfect his creation before revealing it to the overall population in a burst of wonder.
Or on the other hand, as is almost certain, a smart thought may have encountered a terrible begin, however, has been sufficient for individuals to continue and perfect the innovation as it works along.
Solar panels practically endured the destiny of various different creations that were uncovered to general society too early and turned out to be shocking, along these lines pushed to the back of the cabinet and overlooked.
Photovoltaic or PV Solar Panels are also known as solar power systems meaning
light and voltaic meaning electricity from light or specifically from the sun’s rays.
A solar panel is made up of many smaller solar cells- each one can provide a small amount of electrical power.
A solar panel consists of two layers of silicon crystals with each one being treated so that it wants to either loss or gain electrons.
The top layer wants to move its electrons towards the bottom layer and this can only happen when the cell is exposed to light.
The sunlight turns on the electrons on the top layer and they move towards the base layer and to do so
it must pass through metal contacts between the layers.
This is now a circuit and electric power has been produced.
You will need to add more solar panels for your systems to get additional energy.
The more you have the more you are able to produce.
For most homes around 4-8 kilowatt is enough for the basic functioning.
If you have excess energy, you may be able to sell it back to the energy company for profit especially in grid-tied systems.
This certainly does depend on whether this scheme operates in your location.
Getting the electrical power to your home, this type of electrical energy produced by the solar cell is useful,
But not in your home…
It needs to be turned from Direct Current (DC) which is energy from the sun stored in solar batteries
into (Alternating Current) (AC). the energy we use in our homes.
This is done using an inverter which is kept inside your home.
This makes the electricity safe to be used in the home as normal.
Solar panels work only when there is light- not necessarily when it is sunny.
More power will probably be produced when the weather is sunny,
But they will still work even on the cloudiest day.
Solar panels need light – not heat. In fact,
One of the best types of days to produce solar energy is when it is very cold and very bright – like a fresh winter seasons morning.
So, it may be true that electrical power from regular sources such as fossil fuel-fired and gas-fired power stations may be getting more
expensive, but you do have the option of using a renewable energy source which is reliable and easy to use.
Using solar panels alone in most cases at home to produce electricity has brought general doubts in the minds homeowners.
The question is…..
Can solar panels alone power the home throughout the day?
If yes how about nights that there is no sunshine
If no how can I continue to power my house through the night?
Let me show you…
Usually, a utility meter gets installed in a home that wants to connect to the grid before power is supplied.
This meter measures the amount of energy used and supplied to the home.
A number of different meters are used during solar power installation and one
one such is the net metering which most countries especially the US have access to.
In net metering, when your solar panels produce more energy than you need the excess is fed back
to the grid to be used elsewhere or in exchange for power
to be used during the night that there is no sunshine for you to continue to power your home at night and in cases of bad weather.
Do you have a cool tip or projects on solar panels you want me to know?
