product description

A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

In contrast, a solar thermal collector supplies heat by absorbing sunlight, for the purpose of either direct heating or indirect electrical power generation from heat. A "photoelectrolytic cell" (photoelectrochemical cell), on the other hand, refers either to a type of photovoltaic cell (like that developed by Edmond Becquerel and modern dye-sensitized solar cells), or to a device that splits water directly into hydrogen and oxygen using only solar illumination.

Q: How much money can you save by using solar panels?
The amount of money you can save by using solar panels depends on various factors such as your energy consumption, the size of your solar panel system, and the cost of electricity in your area. On average, homeowners can save anywhere from 40% to 70% on their electricity bills by switching to solar panels. However, it's important to consult with a solar energy professional to get an accurate estimate based on your specific circumstances.
Q: I have an electric bicycle that I travel to work by, pulling a modified child carrying trailer that holds two 2 volt deep cycle batteries in series to power the 24 volt bike motor. I'm thinking about adding a 50 watt solar panel (or larger depending on the room I can make available) to charge while I'm at work and to provide some extra juice while on my more distant travels.Can I get a solar panel to charge them while they're connected the way they are: in series? Does charging work that way?I've read that in order to charge the 24 volt battery setup (if the answer to the Q above is yes), the output from my solar panel would need to be a little more than 24 volts. Is this true? If so, how many volts?Since the bike is supposed to be powered at 24 volts and I have an x-volt (x gt; 24v) solar panel connected to it, will this cause any damage to the controller or other components while running them?Will it help supply power even while the motor is being run?Thanks.
Yes, you have it right you need two 2V panels wired in series to give 24V to charge a 24 volt system. But along with the 24V you also want some amperage, otherwise it takes forever to charge. Most of the little chargers are called trickle charges because they only have an amp or two. If you had two 25 watt solar panels putting out 24V you have : watts = volts * amps 50 watt = 24V * x amps x = 2 amps If your battery is say 50 amp hours of storage, then if you are putting in 2 amps it will take you 25 hours of sunlight to power it back up from a dead battery. So the charge time depends on how many amps you are putting in there at 24V A car battery charger typically charges at 0 amps at 2V, so 2 * 0 = 20 watts of power going in there So if you go solar make sure to use a charge controller and a big enough panel to get close to 00 watts for any decent recharge time. The charge controller makes sure that the battery only gets voltage going one way and it least 24V. So if the sun went behind some clouds and the voltage dropped to 20V, the controller shuts off the current until the voltage equals 24V or more
Q: What is the efficiency of solar panels?
The efficiency of solar panels refers to how effectively they convert sunlight into usable electricity. Generally, the efficiency of solar panels ranges from 15 to 20 percent, with some advanced models achieving efficiencies of up to 23 percent. However, it's important to note that the efficiency can vary depending on various factors such as the type of panel, its age, location, and environmental conditions.
Q: Can solar panels be installed on a university campus or educational facility?
Yes, solar panels can certainly be installed on a university campus or educational facility. In fact, many educational institutions have already embraced solar energy as a sustainable and cost-effective solution. Installing solar panels can help universities reduce their carbon footprint, save money on energy costs, and serve as an educational tool for students to learn about renewable energy.
Q: Are photovoltaic cells the same as solar panels?
Solar panels are covered with photovoltaic cells that convert sunlight into electricity. So photovoltaic cells are part of solar panel. renewableenergyarticles.blogspot....
Q: Can solar panels power my entire home?
Yes, solar panels can potentially power your entire home depending on various factors such as the size of your system, energy consumption, and geographical location. It is important to assess your energy needs, install an appropriately sized solar system, and consider factors like sunlight availability to ensure sufficient power generation.
Q: How much energy can a solar panel generate?
The amount of energy a solar panel can generate depends on various factors such as its size, efficiency, location, and weather conditions. On average, a standard solar panel can generate between 250 to 400 watts of electricity per hour under ideal conditions. However, it's important to note that energy production may vary throughout the day and across different seasons.
Q: i am very much interested in making a solar panel, my problem is where i can acquire the main components in order to build it, i am staying here in abu dhabi UAE i'm always searching on the internet for shops that can provide me a DIY kit but i did not find one, i need somebody who knows where i can get these things, please let me know.
