q&a questions

Question:
how many panels of 100 watts need to charge baterys to run a 3000 watts inverter?i have a 12 volts system.
Answer:
No wrong answers here because it depends on how many amp hours of battery storage & how much power you use. I’m in NC where we have steady sun light. I am using (2) 100w panels to charge (4) 100amp hour Weize batteries. I am on a building project and use a 3000w inverters to run 12” desalt miter saw, pancake compressor & circular saw. I have power all day & full power the next day
Question:
when it says 100 watts, is that per hour, per a number of hours, how does that work?
Answer:
Let’s do some quick math, 100 watts in full sunlight on a summer day for 6 hours is 600 watt hours input to a 12 volt 100 amp hour battery. 600 / 12 volts is 50 amp hours. If you have a 100 amp hour battery and your final voltage when the sun goes down is 12 .6 volts you have a somewhat new lead acid battery. At 12.6 volts A new battery will give you all 100 amp hours of it’s capacity by the time it reaches 12.0 volts.
A 3000 watt inverter at 120 volts produces / uses 25 amps. 25 * 60 mins = 1500 amp hrs * 24 hrs = 36000 amp hours per day to feed the monster.

q&a questions

Question:
Most reviewers pair this with the Jackery 500. If I get the smaller 240, is there any advantage in this 100 watt panel rather than the 50?
Answer:
I have a Saga 100 and an Explorer 240 — just got them a week ago. We’ve having a moderately sunny day in NW Florida and I was able to do a 100 percent charge in seven hours. Best numbers I saw on input power were 60 watts but it got the job done in real-world conditions. That said, I have found the Saga to be a bit of a pain as its 8 mm cable doesn’t work with other vendors’ 8mm cables, as it appears that the center conductor is just a mite short, which translates to “you can’t use the 30 foot extension cables from third parties” and “you can’t use the Y-cables from third parties to gang together a bunch of solar panels in cloudy weather.” If I had it to do again, I’d get another vendor’s 18v 100 watt panel.
Question:
Can this charge while you’re actively using a jackery battery powered generator? like if i wanted to use a tv off the generator and extend usage
Answer:
Yes, as long as your usage is less than the input from the solar panel, the inverter is a “pass through” device so it can be charging while in use.

q&a questions

Question:
Looking to get a solar option for charging laptops and small electronics in my van (vandweller). Would this work? or need x2?
Answer:
this kit will work way beyond that as long as you have enough batteries to hook it up to.it can charge your van battery and run 12 volt appliances through your cigarette lighter or run 120 volt appliances with an inverter that can handle the amount of watts you want to use.be careful of sensitive electronics while using a cheap inverter.you may need a sine wave inverter.i would highly recommend a good group of deep cycle batteries.the more batteries the more you can run.check out youtube for lots of answers
Question:
Can this kit be upgraded to the better controller?
Answer:
I question the respondents assessment that the charge controller couldn’t handle a 10% drop in his batteries. I’ve had this set up on my boat for 3 years and it works flawlessly. The charge controller is designed for
3 different types of batteries: Gel, AGM, and flooded. He may have chosen the wrong battery type for his controller. It’s a simple toggle up and down on the controller but if you don’t match your choice to your batteries you will destroy the batteries

4.7/5

q&a questions

Question:
What is a good extension cord to buy with this for more mobility from my RV?
Answer:
There is a lot of wrong and misleading info you’re getting here… It primarily depends on your controller. If you have a garbage (PWM) controller, then 25′ of 10AWG wire is your max. That puts you at 3% voltage drop. If you have an MPPT controller, you can go 55′ with 10AWG wire. Now, here’s the kicker, and the reason nobody should be buying these crappy PWM controllers; If you add another 100W panel in series to your MPPT controller, you can now use 110 feet of wire, and your voltage drop will still be 3% because you’re doubling your voltage. If you add a panel to a PWM controller, you’ll have to cut your wire length in half. DO NOT BUY PWM controllers!
Question:
Anybody know how long you can run the batter/power cable…? I’m thinking from the top of an RV to the ground +/- 12-15′. Thank you in advance.
Answer:
With 10AWG wire between your controller and battery, 30′ of wire will give you 3% drop. Only 15′ of wire could be used if you add a panel and have 200W of PV power. That’s not the best practice though. Best would be to use an MPPT controller connected as close to the battery as possible. You would then be able to use 55′ of 10 guage wire between the controller and panel, or 110′ if you double your voltage by adding another 100 watt panel in series.

4.7/5

q&a questions

Question:
What is the actual maximum power of this panel under real conditions, say a good sunny day, will it reach 100 Watts? I’ve read it won’t no matter what
Answer:
Hellp
Understood that most customer will think for 100w panel, they will get 100w output. But this is theoretical output udder lab condition.
With a good charge controller, under a common environment, you will loss at least 10% in performance from the panel to controller. You can loss a little if your solar panel angle is not 100% towards the sun, you can loss a little if your cable gauge size is not thick enough for the distance you run from panel to controller.
Normally,the actual output is abut 70-80 watts.
Question:
What are the measurements?
Answer:
41.8 x 1.2 x 26.6 inches, thank you

q&a questions

Question:
When the torches are off by means of the switch will they still change during the day?
Answer:
Yes, your instructions when torches arrive is be sure torches off for 2 days, & placed in Sun, to store & give better lite.
Question:
Do these need direct sun to charge, or will just being out in the light charge them?
Answer:
They don’t need direct sun. I have one almost completely shaded and it always comes on. They will actually come out of the box working.
Question:
Does this torch light have two tubes? or need to buy extra tubes to make it 42.9 in high.
Answer:
Each torch light is equipped with two tubes and a connector. So I bought a set of 4 torch lights that come with 4 lights, 8 tubes, 4 connectors and 4 stakes. You can choose whether to use one or two tubes. If you only use one tube, it’s 32.9 in high. If you use two tubes, it’s 43 in high. If you need to make them higher, you need to contact the seller to buy additional extension tubes.Hope this will help you.
Question:
How many led’s? may be missing this, but don’t see it as i do on other solar torches.
Answer:
Specs indicated 99 LED
Question:
How tall are they? (not including the stake portion that is buried in the ground)
Answer:
They are short and fairly fragile, but good for lighting a path or sidewalk. But with some cheap 1\2″ PVC, 1\2″ to 3\4″ connectors for the torch heads, and some black spray paint from Home Depot, I now have stronger 6 ft. tall tiki torches around the perimeter of our deck. (I attached them with stainless steel screws to the deck posts.) 
 

How a Solar Cell Works To Generate Electricity

Generate Electricity
Generate Electricity

The solar cell to generate electricity

Generate Electricity, uses the photovoltaic cell, or what is also called the photovoltaic cell, or in the colloquial language of the solar cell, in order to generate an electric current, and it consists of several photovoltaic transformers, which have the ability to absorb solar energy, and in particular the photons that fall from the sun’s rays , Where the cell works to convert this energy into electrical energy, through the use of the photovoltaic effect, and one of the most important features of the solar cell is that it does not have any negative effects on the environment, and it does not leave any damages.

Definition of the solar cell

A solar cell is a group of thin films made of silicon, and it is distinguished by the presence of negative charges on one side and positive charges on the other side, and the principle of the cell’s work is based on exposing it to sunlight, where the electrons in the cell gain energy from these rays, so they vibrate thermally and work on The bonds are broken, the electrons are released, and the electric current is generated.

How a solar cell works to generate electricity

The tools are:

  • copper sheets.
  • Micrometer device; To measure the current generated.
  • A connector to connect the micrometer to the cell.
  • Glass bowl.
  • Convection oven.
  • Boiling water.
  • Table salt. Sandy leaves; To be used in sanding.
  • Special scissors for metal.

Solar cell work steps

  • Metallic paper shall be cut with metal scissors, with the necessity of the size of the scissors and the volume of gas to be placed on them.
  • Ensure that the copper sheet is clean of dust, oils, or any other stuck materials, which may impede the process of generating electricity, as the cleaning process is carried out using sandpaper, or it is possible to use soapy water but dry it well after washing it.
  • The gas is ignited and placed at a very high temperature, and the clean copper sheet is placed on top of it, and when the paper begins to oxidize, the color of the paper will gradually begin to change, turning from red to orange, then purple, until the color in the final stage becomes black, which is the color of copper oxide.
  • The black paper is placed on the gas for about half an hour, until a thick layer of copper oxide is formed, to be isolated later.
  • Remove the paper from the heat, and set it aside until it cools completely, and he will notice its shrinkage with the cold.
  • The copper oxide layer is removed from the paper after it cools, by placing it under running water, then rubbing it gently by hand, and being careful not to use any sharp materials or wires, so as not to affect the copper oxide layer.
  • A second copper sheet is cut to fit the size of the paper that has been oxidized. The two sheets are folded, and the surface covered with copper oxide remains in the outside direction, with the need to be careful not to touch the two sheets together, and they are placed in the glass container.
  • The collectors are used to connect the anode of the measuring instrument to the copper foil, and the negative electrode of the meter to the copper oxide paper.
  • The container is filled with a saline solution, by dissolving two tablespoons of salt with boiling water, pouring it into the bowl slowly, and being careful not to completely submerge the two slices with water, and it is very important that the water does not approach the tongs, and so the cell is ready for work.
  • The cell is placed directly into the sunlight, which will generate an electric current of about (0.5 to 0.6) microamps.

Solar Energy in Egypt

Solar energy in Egypt
Solar energy in Egypt

Solar energy

Solar Energy in Egypt is one of the most prominent and important modern sources through which energy on the planet can be obtained from solar rays that are outside its field, as this radiation energy reaches 1376 kilowatts per square meter, while the energy of solar radiation is extracted from it is kilo Only one watt per square meter on the earth during noon on sunny days, given that the sun at that time is perpendicular to the earth, and this energy decreases after that time.

The solar rays that reach the Earth are composed of two parts: The first is the rays that reach directly by the sun, and can be used by focusing them with lenses and mirrors designed for this, and the other is the scattered rays that come from the celestial dome, and can be used when the sky is clear, and these rays represent 15% of the total rays.

The exploitation of solar energy in Egypt

The Egyptian country is one of the regions located in the central region of the solar belt in the world, because it is confined between latitudes 22 degrees and 31.5 degrees towards the north, and for this reason it is one of the most global countries that exploit solar energy. The Egyptian policy of research, and the conduct of many studies in order to know the properties of rays in Egypt, through which the knowledge of the extent of the amount of solar energy that can be exploited throughout the year.

Summary of Results

Solar thermal energy

There are many applications that are applied in the country to solar thermal energy for domestic and public heating processes such as (government, private, banks, camps, and hospitals), and it includes heating on water and air that are important in many industrial processes. In electric power generation; Where Egyptian families rely on this technology, which contributes to rationing expenses for families and families.

Solar Power Generator

Solar power generator
Solar power generator

Solar cells

Solar Power Generator, Solar cells are a photoelectric device, and it works to convert the energy emitted from the sun into electrical energy directly, and it depends on the light effect in its work, and the cells used in it are also called photoelectric and photoelectric cells. Solar cells installed on solar panels collect the fallen solar energy and convert it into electrical energy.

A PV Cell

pv cell, called a photovoltaic cell, or a photo voltaic cell, is one of the types of devices that convert the captured energy from the sun into electrical energy without media directly, and it consists of crystalline and amorphous elements, consisting mainly of silicon.

A solar power generator

recently became famous for using solar energy to generate electricity instead of fossil fuels that are threatened with extinction soon, in addition to threatening the environment by exposing the earth to pollution, and many other problems such as increasing the hole in the ozone layer, raising the temperature of the earth, and global warming; This leads to melting snow in the poles, instead of supplying the generator with fuel to work, it is connected to the solar cells that produce energy directly, providing the electric generator and any other device with the necessary energy. There are several types of solar cells, including the following:

  • Cells powered by monocrystalline silicon, and produce 16% energy efficiency.
  • Cells powered with polycrystalline silicon, producing energy with an efficiency of 13%.
  • Morphoid cells: They are operated by depositing layers of silicon on the used solar panels, and they produce energy with an efficiency of 3-6%, and are less expensive than the previous two types.

Problems of using solar energy to generate electricity

    • Pollute the solar panels with dust: and thus lose 50% of their efficiency, they must be cleaned on a monthly basis to ensure their purity, and give them the same level of efficiency required.

 

  • Solar panels depend on the sun and its light to produce energy, so it is not possible to take advantage of these panels to produce energy at night or when the sunlight disappears due to some climatic atmosphere, although the produced energy can be stored for later use, but this process is done using high-cost and additional equipment.
  • High prices for solar cells and their equipment; As they are characterized by high prices and not widespread in the markets; The reason is due to the high cost of the elements that are used in their manufacture and the scarcity of their existence, so they are less used in the country, especially in developing countries.

How to extract Simple Solar Energy

Simple Solar Energy
Simple Solar Energy

Alternative sources of energy

Simple Solar Energy, The source of energy used mainly at the present time is fossil fuels consisting mainly of natural gas, oil, coal and materials derived from them, where other materials can be extracted and the main materials converted to other sub-elements to serve other goals, or to operate machines that depend on the type Specific fuels, but the problems of using fossil fuels became many and other sources of energy had to be searched for.

Problems of using fossil fuels

Among the most prominent problems of fossil fuels are the following: Pollution:

  • where fossil fuels expose the environment to pollution problems; Because they emit harmful substances such as carbon monoxide when burned, and pollution problems have caused great damage to the surface of the earth and humans, and many dangerous diseases related to pollution have appeared that can kill humans and animals.
  • The ozone layer: The ozone layer is perforated, which protects the earth from the leakage of dangerous rays that harm humans and the environment and expose them to great problems, and lead to many diseases, due to pollutants resulting from burning fossil fuels, such as chlorine, fluorine and carbon. Global warming: It helped to raise the global temperature dramatically, which led to the depletion of rain water, and would later cause snow at the poles to melt.

Solar Energy

Solar energy is a form of alternative energy, as it is considered a renewable energy resource, and many modern machines have been invented that capture solar rays and convert them into energy, and modern science is turning to renewable energy resources because of the severe damage caused by fossil fuel sources, and they are threatened with depletion. soon.

How to extract simple solar Energy

One of the simplest methods of extracting and exploiting solar energy is “photo voltaic cells”, known as “PV cells”. Its use is widespread at the present time. Solar cells collect the solar energy emitted from the sun directly and convert it into electrical energy and use it to operate various machines.

It can also be saved for later use, and there are other forms of collecting solar energy such as the solar heater, which is widely spread in the Arab world, especially in the Hashemite Kingdom of Jordan, as it is installed on the roofs of houses and collects solar rays and uses them to raise the temperature and heat water inside the tanks, and it is one of the simple devices to use. , Easy to install, and low cost, and called in English collectors, and there are other types of solar radiation collectors are based on heating the air and fluids in general.

What is the principle of operation of the solar heater

solar heater
solar heater

Solar heater working principle

The solar heater works through special panels that collect solar energy, which are specially made for that, and placed on a sufficient area of ​​the roof of the house, and this energy is used to heat the water in it, as solar water heating can provide 50-80% of the needs of the house From hot water, [1] the heating process begins when sunlight strikes the collector to heat the water inside, and the circulating pump, which is regulated by the PV panel, begins to rotate during the activity of the photovoltaic panel by the amount of absorbed solar energy, then the DC propulsion pump moves the water from the tank through the collector Then return to the tank again. [2]

The sun changes during the day and the speed of the pump changes accordingly, and at the end of the day the process of passing water from the collector to the tank and vice versa has been repeated a lot, so that all the water in the tank becomes hot and usable immediately, but in the event that the periodic pump is organized by an electronic control unit Then, the sensor at the outlet of the collector activates the pump when the water temperature is between 15-20 degrees Fahrenheit, which is warmer than the water at the bottom of the tank, and thus the pump distributes the water to the collector, and the process continues when the water temperature is The collecting port is 5 degrees Fahrenheit higher than the water at the bottom of the tank, and if the temperature drops further, the control unit shuts off the pump automatically. [2]

Active solar heater systems

Active systems are one of the solar heater systems, in which mechanical pumps and control units are used to regulate the flow of heat-carrying water from the solar collector to the tank, where these control devices control the temperature difference between the tank and the solar collector, and the pump is switched when The water in the tank cools and reaches a lower temperature than the temperature of the collector, and some pumps work depending on electricity directly, while others work on the electricity that is generated from the solar photovoltaic panel, and there are some systems that work with solar energy, where liquids move in them when they fall The sun’s rays are used, so that the water is stored in insulated tanks to maintain its temperature during the night periods. Electricity may sometimes be used on cloudy days, when the sun’s rays are shielded.

Passive systems for solar heaters

Passive systems depend on gravity instead of using electricity, which is more efficient in areas with a hot climate, due to the absence of freezing at night or in the winter, where the passive system depends on the heat flow, when cold water flows due to gravity The solar collector, this water passes through the collector to raise its temperature through the phenomenon of convection, and then it reaches the water tank.

How to Use Solar Energy In Homes

Solar Energy In Homes
Solar Energy In Homes

Solar Energy

Solar Energy In Homes, Solar energy Since ancient times, the inhabitants of the earth have used solar radiation in many different applications, including drying agricultural crops before preserving them, and heating homes and Archimedes used solar energy to burn the Roman military fleet in the year 212 BC, as he concentrated solar radiation towards the enemy’s army ships. Using many metal shields, and the women of the Babylonian era used golden vessels to focus solar radiation and obtain fire.

Many scientists have used solar energy to melt minerals, heat the air, convert water into steam, and distill water, and there are global irrigation stations using solar energy, and to the present day man is still devising renewable means to take advantage of solar energy by converting it to other forms.

The advantages of solar energy

  • are a form of renewable and clean energy, and this gives it the advantage of environmental safety as it does not pollute the atmosphere, and it does not leave waste behind, which gives it great advantages compared to others.
  • The technology that is used with solar energy is simple and uncomplicated compared to other energy sources that need the latest and most sophisticated technologies.

Solar energy conversion

Solar energy is characterized by that it can be converted to other forms of energy, such as electric energy and thermal energy, and uses photoelectric conversion technology and thermal energy conversion, and photoelectric conversion is a direct conversion of “light” solar radiation into electrical energy, which is done using solar cells. And in this case, it is important to use materials that work on photoelectric conversion, which are known as semiconductors, the most important of which are silicon and germanium.

This phenomenon was known by physicists in the nineteenth century to bring about a qualitative revolution in the concepts of physics, and from the valuable information that was known at that time that light has the ability to liberate electrons that are present in some metals, just as the blue light has that ability more than yellow light It is reported that Einstein received the Nobel Prize for his ability to explain this phenomenon in 1921 AD.

At the present time, the presence of solar cells, whether in homes, roads, or institutions and companies, has become an obvious matter. One of the most important features that distinguishes these cells is that they do not consist of moving parts, which makes them stable, and they do not need any kind of fuel, and are considered safe for The environment does not pollute the atmosphere, its life span is long and does not need frequent and expensive maintenance, and the principle of its operation is very simple, and its advantages are that it does not consist of any type of optical lens or light concentrators, so the solar panels are installed on the roofs of buildings in certain ways, and then benefit It is used for energy production, and its efficiency in energy production is equal to 20%, while 80% of it is used to provide heating heat, and in the process of heating water.

It can be used in the communication system, road lighting, and pumping water, and it is important to focus on the ability to benefit from solar energy linked to its existence, and for this reason scientists have directed to find special ways to save this energy, and there are many ways to store it, such as thermal, electrical, and mechanical storage. The chemist, and the magnetic.

Solar energy in homes

Solar energy is used in homes for many applications, the most important and most popular of which are home heating and water heating, and it can also be converted into electrical energy, and use it to operate some simple electrical appliances in homes, and at the present time, there are many experiences of using solar energy In home cooking means instead of using gas.
