Q:Solar panel power question?
The specifications you give say the solar panel produces 5 watts at 2 volts (DC) so that isn't enough voltage to power an ordinary (20-volt) light bulb. You could get 0 of these panels and connect them in series so they put out a total of 20 volts and the total power available would be 50 watts. The panels would light the bulb that way, provided the bulb isn't over 50 watts and you can afford the panels. A panel does provide enough power for a 2-volt car light bulb less than 5 watts. However, the maximum current you can get from these panels is .25 amperes (5 watts divided by 2 volts = .25 A.) This isn't enough power to run your pump which takes 6.5 amperes - at 20 volts, that would be 780 watts. Another thing to check is the pump motor; many electric motors are designed to run on AC only and will be damaged if you try to run DC through them. Remember solar panels produce DC so the raw output from a panel will not work on an AC motor.
Q:How to mount solar panel to car.?
What mark said about shade is true, but take into account that the solar panel will absorb most of that heat. That is how they work they absorb the energy (heat) from the sun and transfer it into useable power.
Q:Single Solar Panel savings?
No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?
Q:Making a Charger out of small solar panels?
3-T is just one type of many devices designed to control voltage so you get the amount you desire with as little static as possible. Without you having an degree in engineering, I can't explain it to you any better. You will also need to produce true sine wave energy or you will burn out your PSP with the correct volts and amps. You need one to produce only 5 volts 2amps. Anything different will burn out yur PSP. Your problem is simple math. Watts = volts multiplied by amps. Amps = Watts divided by volts. So if your solar panels can produce /4 amp ( 250 mA) each, then you connect one to the other in a series until you get enough connected to make 2A. ( 8 panels { /4mA x 8 = 2A}) You now have a panel with 32Volts, 2Amps, 64 Watts. This is where the T-3 regulator comes in. If you buy one for 5 volts, it will allow only 5 volts 2 amps, to go to your PSP.
Q:Solar panel battery charging?
it depends how big the panel is. a small trickle charger (like a 2W panel with built-in diode), just connect + to + and - to - (parallel) to trickle charge the battery. The diode will keep the batter from discharging through the panel when there is insufficient sunlight. for a large panel (like a 220W 24v panel), you best go through a charge controller. the charge controller has 2 leads for the solar panel input, 2 leads for the battery connection and 2 leads for the 2v load. just follow the instructions to connect the panel and battery to the controller, and MAKE SURE YOU USE THE REQUIRED FUSES. very straightforward stuff -- just RTFM
Q:Why are solar panels placed on the roof of houses?
Solar panels are placed on the roof because many times the roof has good exposure to the sun providing the roof is not blocked by trees or something else so that sufficient sunlight wouldn't be absorbed. Also the panels would more likely not get damaged on the roof opposed to being in the yard. If they were mounted on the windows, how could you see? And, the windows could easily break and then what would happen to the panels? Placing the solar panels on the floor would not be practical. A lot of sunlight is needed for the cells to produce electricity and how much goes on the floor? Most roofs are at an angle which could perhaps improve the amount of sunlight the panels would get, and roofs provide a lot of unused space. The roof is the best place. Furthermore, roof solar panels are available now to blend in better with the roof so that they are more pleasing to the eye. Even if you have a small roof, some panels could be placed there provided the roof is not blocked so that the sunlight it gets would be sufficient (about 4 or 5 hours of sunlight a day is needed). And, if you needed addition panels, they could be mounted in your yard as long as the mount was close to your power box and received sufficient sunlight. I applaud your desire to use solar panels. You could possibly save 50 - 90% on your electric bill and help your environment at the same time! A Win - Win situation!!
Q:how many solar panels and what type to power a laptop computer that has to be plugged in when in use?
There okorder.com/ Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:so i'm wanting to eventually get solar panels.?
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.
Q:Numbers behind Solar Panels?
For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.
Q:Does infrared radition occur in solar panels?
- Radiation from the sun is mostly Ultra- Violet. - There are 2 types of solar panels, Solar thermal collectors and photovoltaic cells. - Put simply, photovoltaic cells take the UV rays and produce electricity. - Solar thermal collectors (which is probabl
