Q: we are planing to move out of the grid. we need to operate constantly 2 laptops online - does any one can tell us how much solar panels we shall need to make sure of that?: Create okorder

Q: can u use a light bulb instead of the sun to power a solar panel: Yes, but why? If you've got the light-bulb, you've already got more electricity than you will get out of the solar panel.

Q: I'm doing a project for school and I'm a little confused about energy and solar panels. I'm looking to propose installation of solar panels to power the computer lab at my school. From what I've read a computer and monitor use roughly 350 watts per hour. I was looking at solar panels and it says they produce various wattage. For example, I was looking at one rated at 200 watts. Does that mean 200 watts in a day? Or per hour? Please help.: The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.

Q: Can solar panels be used to power a farm?: Yes, solar panels can be used to power a farm. By harnessing the sun's energy, solar panels can generate electricity that can be used to power various farm operations such as pumps, irrigation systems, lighting, and even machinery. This renewable energy source offers a sustainable and cost-effective solution for farmers looking to reduce their reliance on traditional power sources and reduce their carbon footprint.

Q: Solar panels are all divided into these squares, forming a grid like pattern. Is it possible to have a single piece of solar panel?: These grids are required to absorb heat from sun and increasing the energy productivity :)

Q: I have purchased a 2 volt LED lantern from argos, it comes with a built in 6 volt 4ah sealed acid battery. What I wanted to know is would I be able to charge it using my 6 volt solar panel?: If it has a 6 volt battery- is it marked 2 volts on an external plug? If so, there is a resistor inside to drop the potential the battery sees. The battery itself could be slipped out and recharged easily from your 6 volt panel. Just determine how much current (in Amps or Milliamps) the panel produces nominally and divide that into 4 and add one fourth of that length of time to make up for system losses. This will tell you how many hours it should charge assuming your starting voltage of the battery is above .5 volts. and the panel is at 3 volts potential or higher. So if your panel puts out amp at 0AM, you would charge for 5 hours. 4 divided by is 4 and one fourth of that is so 4 plus is 5. It is a little more involved than that, but as a rule of thumb. Also do not discharge tha lantern to the point of no light output. LEDs are efficient, but their current will add up. If it is suggest to be able to use the lantern for up to 8 hours on a charge, stick to that value. Lead acid batteries have best longevity when discharged only to 80 percent capacity. Once battery is charged- disconnect from charging source.

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: How do solar panels impact the roofing material's lifespan?: Solar panels can actually extend the lifespan of roofing materials. They act as a protective layer, shielding the roof from various weather elements like UV rays, hail, and rain, which can cause damage over time. Additionally, solar panels can help regulate the temperature of the roof, preventing excessive heat buildup that can accelerate the degradation of roofing materials.

Q: Installing solar panels requires a big initial investment. Before I make this investment I want to check to see if the money I will save by installing solar panels will actually pay for this investment, in the long run. To calculate my savings, we should consider the area (square feet) I currently have available to install solar panels. Look at the available sunlight and its intensity in my state each month of the year. Based on this data estimate how much energy my solar panel will generate. Then compare that with how much energy (kWh) I currently consume based on my electricity bill.: Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.

Q: I want to build a standalone wifi repeater -- powered by the sun. The problem is how much solar power and how big of a battery?net draw 4.5v @ 0.66A with loadnet draw 4.5v @ 0.60A no loadI'm assuming the best choice would be a 6v battery with a a couple diodes in series to induce ~.5v drop. Then, I need something to charge it -- I found 2v 6w solar chargers in the automotive section of Sears and 6v 2w solar chargers in the marine section of Dick's Sporting Goods.How many solar panels and what capacity batteries should I use? Is this the best method or should I use a voltage regulator and go with 2v batteries?I need this to be as cheap and simple as possible...: You won't get very far with THAT lash-up. First of all.. WHY would you want to use diodes to drop the voltage.. they DRAW CURRENT and that is something you don't have to spare. That draw of (660 ma) comes out to just under 3 watts. You DO KNOW that you can get that 4.5 Volts by driving a NAIL into the THIRD CELL in a 6 Volt wet cell battery... right? and for what you are doing, you have more current available with a 6 volt battery than a 2 volt battery. Anyway, you could use two 6 Volt batteries and tap them at the 4.5 volt point then tie them in parallel, but you could still use the 6 volt solar panel to charge them. Trying to use an inverter is just an exercise in futility.. With TWO of the LARGEST DEEP CYCLE BATTERIES you can buy at AutoZone running in Parallel and being charged by solar panels.. if you hook a 75 watt inverter to them, they will go flat in about 4 hours of use during the night. This is not rocket science. Back when cars were changing over from 6 volts to 2 volts, I powered up more than one 6 volt car radio off a 2 volt battery... when you grow up as poor as I did.. you get inventive. I later used the same trick on the 24 volt electrical systems the Jeeps were using, to power up clandestine repeaters in places where no repeaters should have been. About 25 years ago I was living in the Denver area and built up a 0 watt 2 meter repeater on a split channel and took it up to Mt. Evans during the summer and hid it in a pile of rocks. I used tone control, so we were the only ones using it and, as I said, It was a split channel.. so it wasn't on a regular repeater channel. That thing was still running when I moved from the Denver area about 3 years later and for all I know, It's still up there on Mt. Evans (find the Brittlecone Pines and look towards that small peak about a mile to the west)
