- Q:With no moving parts, no fuel piping and so on...

- Q:Can solar panels be installed on a greenhouse?
- Yes, solar panels can be installed on a greenhouse. In fact, it is a popular practice to install solar panels on greenhouses as it allows for sustainable energy production while utilizing the available rooftop space. The solar panels can help power the greenhouse's electrical systems, such as ventilation, lighting, and irrigation, reducing reliance on external energy sources. Additionally, the panels can provide shade and protection to the greenhouse, helping to regulate temperature and improve overall energy efficiency.
- Q:If we invest billions in green energy and put up thousands of square miles of black panels that give off radiant heat couldn't that significantly cause more warming, not to mention the energy required to even make them?
- Essentially, solar panels are 'warming neutral'. They absorb energy that would otherwise have heated whatever was behind them, thus have a local cooling effect. This is balanced by the generation of heat when the electricity is used to power, say, a hoover, TV, computer etc, also from 'transmission losses' through the national grid network. Good answers from Claire and Linlyons, bizarre answer from Jim! Tomcat may have a point though...
- 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 efficient source of energy to power the irrigation system, reducing reliance on traditional electricity sources and reducing operational costs for farmers. Additionally, solar panels can help farmers become more environmentally friendly by reducing carbon emissions associated with irrigation.
- Q:what kind of rays are used in solar panels?
- Electromagnetic...meaning light rays, primarily in the visible spectrum. Ultraviolet and infrared light rays actually degrade most types of solar panels, limiting their useful lifetime. That said, your question is not stated well...so I'm not sure if that's the information you were looking for. Rays are not used in solar panels...rather solar panels are used to collect sunlight and convert it to energy--either directly into heat in the case of passive solar, or into electricity by the use of photovoltaic cells.
- Q:Can solar panels be used in areas with high levels of dust storms?
- Yes, solar panels can still be used in areas with high levels of dust storms. However, it is important to ensure regular maintenance and cleaning of the panels to prevent dust accumulation, which can reduce their efficiency.
- Q:This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
- It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
- Q:i am trying to figure out how many solar panels can be placed on one acre of land and how much they cost to install
- HOW MANY PANELS FIT IN THE ACRE FIELD? acre = 43560ft? First of all you can not fill the whole acre field with solar panels. There must be space between them so you can walk amongst them and so they don't shade each other. So let's say you can maximally cover 50% of the area. 43560ft?/2= 2780ft? a medium efficient, medium priced polycrystalline solar panel of 200w covers 6ft?. So how many can we fit in your field: 2780ft?/6ft?= 36pcs of 200W solar panels can fit on the field 36pcs*200w= 272200W =272kW of total power harvesting capacity per full sunny hour. HOW MUCH WILL THE PANELS COST? Since you will build such a large solar farm you will want to get the cheapest panels possible. the price per watt on solar panels today is as low as $,5. that will mount up to: 272200W in total *$,5 cost per watt = $408300 for all the solar panels HOW MUCH WILL THE EVERYTHING COST? The whole shebang will be much more expensive since you are going to need inverters, wiring, fuse boxes, handy men to install it all and so on. A 5kW total solar system costs about $0000 if bought from a solar company. that would mean $0 000 * 272200W/5000W= $544 400 for the whole shebang But I strongly believe since you are buying such large quantities you will be able to get better deals then the rest of us mortals. And then you will have a power plant making you free electricity for the next 25- 40 years to come. And you don't necessarily need to set it up in a particularly sunny place for it to be cost effective. Just look at this gorgeous solar Farm from France
- Q:How do solar panels perform in extreme temperatures?
- Solar panels perform best in moderate temperatures, typically between 25 to 35 degrees Celsius. However, extreme temperatures can affect their performance. In extremely hot temperatures, solar panels may experience a decrease in efficiency due to an increase in heat-induced resistance. On the other hand, in extremely cold temperatures, solar panels may experience a slight increase in efficiency, as lower temperatures can reduce resistance and improve conductivity. Nonetheless, most solar panels are designed to withstand a wide range of temperatures and can still generate electricity in extreme weather conditions.
- Q:planning to get one, for a store/house, we use alot of electricity at least 500-3000 dollars a month. how much money would this save us? how big would we have to get the solar panel?[aproximately]
- There are a lot of factors to consider. Net metering, utility rates, number of hours of daylight, size and orientation of roof or other location. I can tell you I had a 3.74 kwhdc system which reduces my bill by about $200 a month. It cost $26K installed, I received a $0K rebate from my utility and a $2K federal tax credit. Businesses have always been able to get a 30% fed. tax credit, this year everyone gets it. If this is a business you plan on owning for a long time there is no reason why you can't do the install in stages. Of course making sure you are conserving as much energy as possible will also help. Using energy efficient lighting, appliances and electronics, Turning off lights, monitors, computers, printers etc when people go home, sharing printers and other resources, adjusting the thermostat and using natural light can all help reduce your electricity usage.
