- 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: What size of system would I need to get if I use on average 500 kilowatt hrs a month I would like to do a tie in grid system I live in the states south central area of States any info or links to sites would be wonderful I am interested in this type of energy soure thank you

- Q: How do solar panels affect the property's energy management system?
- Solar panels can have a significant impact on a property's energy management system. By harnessing the power of the sun, solar panels generate clean and renewable energy, reducing the property's reliance on traditional energy sources. This allows for greater energy independence and can result in substantial cost savings on electricity bills. Additionally, solar panels can feed surplus energy back into the grid, further optimizing energy management and potentially earning credits or incentives. Overall, solar panels play a crucial role in enhancing the efficiency and sustainability of a property's energy management system.
- 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: Hi there. I live in Colorado, and we obviously get a ton of snow there. I im looking into a solar power system for my home, and I am wondering if the snow will accumulate on the panels, or if, because of the energy passing through, it will melt on contact? By the way we get about 20' of snow each year, and it comes on often. I will also be putting them on my roof. Thanks for your help.
- If you have an electrical backup you could install something to melt the show where the solar panels are installed. You might try installing them near a fireplace chimney if you have one. My thinking tells me if you have a clear raised bubble or pyramid over the panels it might help.
- Q: Can solar panels be installed on churches or religious buildings?
- Yes, solar panels can certainly be installed on churches or religious buildings. In fact, many religious institutions have embraced solar energy as a way to reduce their carbon footprint and demonstrate their commitment to environmental stewardship. Installing solar panels on churches not only helps to generate clean, renewable energy but can also serve as an educational example for the community.
- Q: Can solar panels be installed on airports?
- Yes, solar panels can be installed on airports. In fact, many airports around the world have already adopted solar power systems to generate clean and renewable energy. These panels can be installed on rooftops, parking lots, or open spaces within the airport premises, effectively reducing their reliance on traditional energy sources and contributing to a more sustainable aviation industry.
- Q: (For a project)I know they are made of silicon, but I want to EVERYTHING they are made of. Ex Metal (What kind)Please tell me everything used from their production to the finished projectThank you
- Solar panels are slabs of semi-conductor metal. Technically speaking, they are a slab of silicon semi-conductor doped or added with impurities to make it a better conductor. Solar panels could also be made of Gallium Arsenide which is a semi-conductor metal exclusively used in photo-voltaic cells.The silicon slabs are polished and glossed before doping. After processing, for protection, a thin glass layer is embossed on the solar cells slab. Silicon also is shiny and reflects about 35% of sunlight. Hence, an anti-reflective coating is usually applied over the slabs to reduce the amount of sunlight lost.
- Q: I'm doing a project for school where I will buy a solar panel and utilize/improve the power output of the panel. I want the panel to have an improved amount of energy output compared to the original. My budget for the solar panel itself is ~$00. Anything else that will be needed is covered.Also, I will be comparing the power by lighting a light bulb and checking to see the output energy of the panel.Where or how should I approach this project?What are the parts of the solar panel that I will need to buy?What factors could I change/improve to improve the overall energy output?What are the things (other than the panel) that I will need to buy?How can I attach a light bulb to the solar panel?
- The okorder to find the info there.
- Q: I am building a solar car for the energy wiz competition and I was wondering how I could possibly get my solar panel to shift sideways
- having solar panels move like that on a mobile platform is inadvisable -- especially if there is a dynamic wind load resulting from the motion of the mobile platform. Even having a tilt mechanism is dubious at best. think of what limited marginal gain would be gained by mounting a small solar panel on the moon roof of a car. (ultimately, the best answer is to turn the car so that it's angle to the sun is optimal -- but the road/travel direction constraints are what ultimately prohibit that.) while there are ways to build sliding panels, the weight constraints would interfere with your weight/thrust ratios to the point of futility. if you really need that panel somewhere else, don't slide it out of the way, just buy another panel and mount it there. it's more expensive, but it's actually the cheapest solution in terms of design on a mobile platform.
