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.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

Q:How do solar panels affect the roof's lifespan?
Solar panels can actually help extend the lifespan of a roof. They act as a protective layer, shielding the roof from harmful elements such as UV rays, rain, and snow. Additionally, solar panels can reduce the temperature of the roof, which can help prevent heat-related damage.
Q:I would like to know if I had a mobile kitchen could I power it from solar panels mounted atop the vehicle (truck).(to power electric kitchen equipment, i.e. stove, deep fryer.), instead of propane…could I possibly connect the solar panels to a battery to save my generated electricity? If solar panels would not be enough power could a small windmill suffice…?
The best way to find out is to determine the wattage of each piece of equipment you want to use and how many hours you want to use those pieces of equipment. Finally, calculate the total number of Watt-Hours you need at minimum. Then you need to research solar panels or mobile wind mills (they need to be pretty huge to get a decent amount of energy I think, so solar power is probably the way to go). You will need to figure out the efficiency of the solar panels, the size of the array, how you will turn it or if you will turn it at all (to face the sun to get the maximum energy input, or maybe to use mirrors so you don't have to turn it. Once you find a good configuration for your mobile kitchen, you need to calculate if the Watt-Hours you will generate on an average day (with average weather) is enough to power the equipment whose energy requirements you previously calculated. Then you have to keep in mind that some days will have no sun, and you may not be working on some days, but you can still capture sunlight. For each case, a large battery array will be required. If you had a guage on that array, you could also hook it up to the a small generator in case you need immediate power. It's an eco-friendly process, but the initial cost is high and it requires a lot of research and planning. This is why most people do not do it--not because they don't want free energy from the sun, but because it's not easy to start collecting that energy in an efficient way. Sorry I couldn't give you more specific numbers, but a solar panel sales agency should be able to estimate whether or not you could do it (they'd probably set it all up for you too). ^_^
Q:Could you have a solar panel in space that would transmit electricity remotely? Maybe have some kind of receiving antenna to pick up the energy? Perhaps there could be a string of them orbiting the Earth?Why wouldn't that work?
Wireless okorder . May be in future research will give a means to harness solar energy from space.
Q:Can solar panels be used to power a concert venue?
Yes, solar panels can be used to power a concert venue. By installing a sufficient number of solar panels, a concert venue can generate enough electricity to meet its power requirements, including stage lighting, sound systems, and other electrical equipment needed for the event. Additionally, solar panels can help reduce the venue's carbon footprint and dependence on traditional energy sources, making it a more sustainable and environmentally friendly choice.
Q:I have a solar panel, charge regulator, inverter....is that all I need to tie it into my grid? Do I just plug the solar panel into the charge regulator into the inverter into any 0v outlet? I feel like im missing something....
No don't do that unless you want a fire or worse electricution . DO NOT PLUG INTO THE WALL . st solar panel 2nd regulator 3rd 2 volt battery 4th inverter . The inverter should have 0 volt terminals that look like the plug on the wall . You would plug your TV or light into that the inverter . You would need an electrition to hook into your home electrical system . They will hook up a device made to tie into the grid or your meter that will make it run backwards but it takes alot of solar panels too do that . Please do not plug into wall .
Q:Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?
Taken at face value, it would take about 55 hours to re-charge a dead flat battery. However, you don't get 24hrs/day sunlight. Even worse, the output from a panel is only maximum when the sun is at 90 degrees to the surface. Let's assume you can find some way to track the sun. No battery should be allowed to discharge below about 50% so we can halve the recharge time. I would say about 4 days.
Q:If i wanted to get a 5 KW solar Panel does it mean it produces 5KW a day/hour/year!?!?i need 2555.35KW a week and i don't know how many or what kind of solar panels i need.Please somebody help me
First, learn the difference between kilowatts and kilowatt hours, and all shall be made clear.
Q:What are the advantages of using solar panels?
There are several advantages of using solar panels. Firstly, solar energy is a renewable source that does not deplete natural resources, making it environmentally friendly. Additionally, solar panels produce clean energy, reducing greenhouse gas emissions and combating climate change. Solar power can also save money in the long run, as it reduces or eliminates electricity bills. Moreover, solar panels require minimal maintenance and have a long lifespan, making them a reliable and cost-effective energy solution. Finally, solar energy can provide energy independence, as it can be generated on-site, reducing reliance on traditional power grids.
Q:ok so when a solar panel is marked as a certain wattage dose that mean it makes that much in a day in an hour or constant, dose it still work at night or what ? is it worth it or is it more of a pain? can some one tell me what all the watts and volts mean ?? and can some one tell me what a kilowhat is in refrence to some thing i understand like howmany loads of laundey can you do wt a watt? i need help understanding this stuff?

Q:i've heard environmentalists like ed begley jr use the phrase quot;peak shaving hourswhen talking about solar energy.what does that phrase mean, please?thank you to all who respond.
Graminoids are among the most versatile life forms. They became widespread toward the end of the Cretaceous period, and fossilized dinosaur dung (coprolites) have been found containing phytoliths of a variety that include grasses that are related to modern rice and bamboo. Grasses have adapted to conditions in lush rain forests, dry deserts, cold mountains and even intertidal habitats, and are now the most widespread plant type; grass is a valuable source of food and energy for all sorts of wildlife and organics. Graminoids are the dominant vegetation in many habitats, including grassland, salt-marsh, reedswamp and steppes. They also occur as a smaller part of the vegetation in almost every other terrestrial habitat. There are some 3,500 species of graminoids. Many types of animals eat grass as their main source of food, and are called graminivores – these include cattle, sheep, horses, rabbits and many invertebrates, such as grasshoppers and the caterpillars of many brown butterflies. Grasses are also eaten by omnivorous or even occasionally by primarily carnivorous animals. In the study of ecological communities, herbaceous plants are divided into graminoids and forbs, which are herbaceous dicotyledons, mostly with broad leaves.
