- Q: Solar panel experiment ?wat are some experiments with solar panels that has not yet been proven? ideas
- You okorder /
- Q: Can solar panels be recycled? What about the manufacturing of these panels is it done in an Eco-friendly way?
- Most of the early panels were not very green. They were not very efficient and did not have a real long life span. The newer one are getting much better and there are several companies have cropped up that rebuild many different kinds of panels. Some of these newer panels have a life span in excess of 30 years and are much easier to maintain. The biggest problem with solar systems is that they are not kept clean and loose efficiency. If interested in setting up a system for your self, Please be very careful who you have do the work and what system you buy. There are many companies out there that are just trying to make a quick buck at your expense.
- Q: What is the main material for making solar panels?
- You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
- Q: I read on CNN's website last year some company was creating a very cheap type of solar panel, that needs minimal maintenance and and has minimal glare from the sun. And the creator of the project said he one day wanted to cover every rooftop in the US with these solar panels. Seems like a good idea to me but I havent heared anything of it for a long time and I don't know what they are called... any help?
- The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
- Q: I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?
- Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.
- Q: Alright my family and i are buying a new home in Bradford,Ontario, we we thinking about solar panels and had a couple questions:. how much are they each?2. how many will we need to power a single family home(4 ppl)3. where can we find them in ontario?4.how much money do they really save you?5.what kind of energy do they providfe you withand other basic info or a website i can check out would be great!thanks in advance!
- I have a system that was installed last year. I have 20 panels which provide me with about 75% of my electricity. I do use less electricity than the average home. I use an average of 45 kwh in the summer, my neighbor uses more than double that. I paid $26K for the system, but I got a $0K rebate from my utility and the US gives a fed. tax credit. I am saving about $2K per year, so it will take just over 6 years to break even. I also have what I think is called net metering, my utility allows my meter to run backwards when I generate more energy than I use, so pretty much the entire time the sun is out in the summer. Having energy efficient appliances, reducing standby energy and using conservative climate control really helps keep my usage down. Weather striping, insulation and clean well maintained systems all help as well.
- Q: Can solar panels be installed on agricultural irrigation systems?
- Yes, solar panels can be installed on agricultural irrigation systems. They can provide a sustainable and renewable source of energy to power irrigation pumps, reducing reliance on fossil fuels and lowering operational costs for farmers. Additionally, solar panels are compatible with various irrigation system configurations and can be easily integrated to support the water needs of crop production.
- Q: How much space do solar panels require?
- The amount of space required for solar panels can vary depending on factors such as the type and size of the panels, their efficiency, and the energy needs of the system. On average, an average-sized residential solar panel system typically requires around 100-400 square feet of roof space. However, ground-mounted systems can require larger areas, and more efficient panels can generate the same amount of electricity in a smaller space.
- Q: solar panels are way too expensive to buy, can they be homemade cheaply? i want at least 500 watts. everyone on the web sells these instructions, but i'd like a link to free info, if it is really possible for a non-sciencey person to make. thank you
- The idea is to hand assemble scrap solar cells that would otherwise be thrown out. At one point in time, very few people would want to do this so you could get the broken solar cells for free but now they sell them by the watt. It's still cheaper than a pre-fabricated solar panel but it's very labour intensive. Technically it's like wiring a bunch of batteries together, you measure the voltage and current a broken cell produces and decide whether or not to wire it in series or in parallel with other cells to get the performance characteristics that you want plus try to fit them onto some kind of structural panel in a fashion that uses the space efficiently. Since your handiwork is likely to be fragile, you'll probably have to put some plate glass on top to protect the cells from the elements, you can also improve performance by positioning fresnel lenses to increase the amount of light on active elements versus inactive areas of the panel.
- Q: Can solar panels be installed in urban areas?
- Yes, solar panels can be installed in urban areas. In fact, urban areas provide great opportunities for solar panel installations due to the abundance of rooftop space and potential to generate clean energy in densely populated areas.
