- Q: Can solar panels be used in commercial buildings?
- Yes, solar panels can definitely be used in commercial buildings. In fact, many businesses are increasingly installing solar panels on their rooftops or in open spaces to generate clean and renewable energy. This helps reduce their reliance on traditional grid electricity and lowers their operational costs in the long run. Additionally, commercial buildings often have ample roof space, making them ideal for maximizing solar energy generation.
- Q: How do solar panels impact wildlife?
- Solar panels have minimal impact on wildlife compared to other forms of energy generation. While there may be some concerns about the disruption of habitats during installation, once operational, solar panels do not emit greenhouse gases or pollutants, reducing air and water pollution that can harm wildlife. Additionally, solar panels typically occupy a small fraction of land and can be installed on rooftops or in areas with limited biodiversity, minimizing the impact on wildlife habitats.
- Q: I would like to connect a solar panel to a small fan. I am not sure as to what is needed to actually quot;connectthe two together. Any help is appreciated.
- Panels are rated nominally, and you can look at your fan to see what the ratings for the fam are to determine sizing of the panel. Current multiplied by the volts (rated) gives you the wattage of the motor- just use this as a guide for sizing the panel. You do want a little more power from the panel than the motor draws for purposes of starting the motor and for having the fan operate at lower sun angles as well. You can add a battery if you chose, but it is not a requirement. Just treat the leads of the panel like those of a battery red (+) and black (-) just connect those to the fan, if you match color for color, no problem. If the markings are not present and no wires are on the fan, try it one way, if it is the wrong way- reverse them. AC operated fans will require an inverter to convert the DC to AC. These draw a certain amount of power as well. In general the same rules of thumb apply. It is just easier though to stick with a DC motor.
- Q: Solar panels would change the world if they were widely available to us especially cheap, it will be worth it in the long end. Money would be saved like housands a year per person on utility costs.
- Yes, solar panels could change the world if they were especially cheap--but they're not and may not be cheap for many years, if ever. Lots of new technology could change the world but most of it doesn't. The government doesn't have a very good track record of picking winners in the new technology markets; that's something we should probably leave to the venture capitalists to do--with their own money. The money the government spent on solar panels is gone. Racked up as debt that we'll leave to our children and grandchildren to pay off.
- Q: Say if i had a 2KW system is thtat just one big solar panel or does the whole system have little solarpanels together.?
- As Aviophage says, there is plenty of info around. Solar panels produce electrical energy from the sunlight's energy. The sun puts out around 00W per square meter, and the panels are up to 20% efficient at converting this. If you are looking for a Grid Connected power system, they are usually made up of 24V modules about 50W each. The full voltage produced is then around 50V to 500V DC depending on the sun etc. They are connected to a specialised grid connect or grid interactive inverter (look up Sunny Boy for an example) which converts this to mains power for use around the house, while any remainder is exported to the supply network. The supply company may buy this at premium rates, and governments may provide subsidies to approved installations. There may also be carbon credit certificates when you buy a system. Not all places allow such things to be connected to the grid, but this market is rapidly changing. The links below should get you started.
- Q: How to Compare Solar Panels? ?
- Each okorder may help you
- Q: what parts and tool do i need to build and connect a solar electric panel to my home
- Solar energy is very expensive. Or I should say, solar panels are expensive, because once you install them the power is free. A typical residential solar power system that supplies around a kilowatt of power at best conditions (noon, sunny day) will cost about $0,000. This includes the solar panel, the inverter (converts DC into AC), the cabling, but not installation (that would probably run you another $2000). One kilowatt is not that much electricity. It would run one microwave oven, or one hair dryer, or 0 light bulbs, and nothing else. Most houses use 3 times that at peak hours. So you would still likely get some power off the grid at peak time, and other times you can sell it back to make a little money. The good news is that solar panels are getting cheaper. They are around $5 per watt now, and are projected to drop to half that in the next decade. At some point, it will reach the sweet spot that makes solar an attractive alternative to grid power and more people will jump on board. There are some tax incentives too, but more would certainly help.
- Q: How do solar panels impact the local economy?
- Solar panels can have a positive impact on the local economy in several ways. Firstly, the installation and maintenance of solar panels create jobs, stimulating employment opportunities. Additionally, solar energy reduces the dependence on fossil fuels, thereby decreasing energy costs and increasing savings for businesses and households. This can lead to more disposable income, which can be spent locally, contributing to economic growth. Moreover, solar energy projects attract investments and promote the growth of renewable energy industries, further boosting the local economy.
- Q: Are solar Panels worth it, Do they really quot;save moneyon electricity?
- Solar panel systems are one of today's best investments! What other product can you get that last for 25 years or more and saves you money every day of the year, but pays itself off in 5 to 0 years in most cases. Our company has installed well over 00 solar panels systems for clients who have declared independence from their utility! Contact us to learn more if you are in the Northeast US.
- Q: I just connected my 5 Watt 2V solar panel directly to my 300 Watt 2 inverter. It worked for about 2 minutes then it popped (sparks, smoke etc)! What the hell did I do wrong? I thought the solar panel was 2 volts? Can someone with experience with these things help me out?
- . A 5 WATT panel can NOT power a 300 WATT inverter. 2. IF using 2 volts, then you need a 2 volt battery in the circuit as well. Panel charges battery which powers inverter. When the inverter pulls more power than the panel puts out, it gets it from the battery until the voltage drops low enough to shut down the inverter. NOTE: SOME cheap units do NOT have protective circuitry, and when the voltage drops, the current rises and burns them up.
