- Q: What does it take to install the solar panel? Cable wires to power source or fuse box? Anything else?How does the cable wires stay on the solar panel?
- How does the cable wires stay on the solar panel? With wire retention clips (4 per module) that are used to wrap the wire on the underside of the module frame. The home run cables to the transition box (converts between types of wire with no electrical transformation occuring) or combiner box (joins multiple source circuits in parallel, with the positives fused for safety) are usually tied along the racking system components, and with conduit sections used as needed. Racking is another big part of the installation. Don't just make your own homemade wooden rack, as these will weather away to nothing very easily, and cause great failures. GET a professionally designed metal racking system. PV modules are EXPENSIVE. Don't let the racking system cause them to break. It also requires the inverter, if you intend it to connect to the main electric service. If using multiple inverters, you need an AC combining panelboard to join them prior to entering the main electric service. Otherwise, you need to think about how else you might be using them. If you are charging batteries, you need a charge controller.
- Q: I'm looking to mount a solar panel to the top of my 2003 Pontiac Montana and was wondering how i could do it without any screws? Magnets maybe?
- 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: our school spends around $0,000 dollars on energy.we want to know how much money would installing solar panels on the roof save our school.
- 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: Can solar panels be installed on airports or transportation hubs?
- Yes, solar panels can be installed on airports or transportation hubs. In fact, many airports and transportation hubs around the world have already implemented solar panel systems to generate clean and renewable energy. These installations not only help reduce the carbon footprint of these facilities but also contribute to their energy self-sufficiency and cost savings.
- Q: Can solar panels be installed on a historical building?
- Yes, solar panels can be installed on a historical building. However, it is essential to consider the building's architectural significance, structural stability, and local preservation regulations. The installation should be done in a way that respects and preserves the historical character of the building while providing the benefits of renewable energy.
- Q: Can solar panels work in the shade?
- YES. They work in direct proportion to the amount of light falling on the surface, regardless of the source of the light. In the shade simply means reflected light instead of direct sunlight, falls on the panel, with that much less output. The earth has an albedo of about 8, which meas about 8% of the light falling on the earth is reflected. The moon has an albedo of 2, which means 2% is reflected, which is why shadows on the moon are not jet black as you might expect in an airless place. The atmosphere of the earth is why shadows are lit as they are. The conspiracy theorists thought they had something to prove the moon landings were faked with the shadows not being black. They neglected to account for reflected light from surrounding sunlit objects scattering light the shadows.
- Q: I'm making a model of a solar photovoltaic tower for a school project. I need a way to store energy, and we thought about using capacitors (mainly because of our somewhat limited funding). The tower will have a small photovoltaic panel (around the size of a laptop keyboard with number pad) and some (around 50) quot;heliostats(just the mirrors, no moving parts). What kind of capacitors should i use? and would a capacitor bank be better? i am getting confused with all those uF, pF and can't see the difference.Thanx in advance
- Solar Capacitor
- Q: Can solar panels be installed in urban areas?
- Yes, solar panels can be installed in urban areas. In fact, they are increasingly being installed on rooftops, facades, and even integrated into buildings in cities around the world. Urban areas offer ample opportunities for solar panel installation, promoting clean energy generation and reducing dependence on fossil fuels.
- Q: Is it good? ( solar energy)
- I think solar panels benefit people a lot,it is worth buyingsolar power can be converted into heat energy and electricity which be used into daily human life,more convenient and safe，Also,solar power will not discharge any polluted gas,it can protect our earth.As for the negative,the price of solar power is a little higher at first pay,but you will not pay any fees any more.
- 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)
