- Q: discription how does solar panels save energy
- I'm definitely no expert in the field but hope to learn much more in the future. I'm in the infancy stage of researching as many options as possible in the design and construction of a total green house. That being said, a particular local news story sparked my interest when they investigated the cost effectiveness of residential solar panel systems. Here in Austin, Texas, through subsidies and incentives offered, you can install a system that costs roughly 22.5k for about 7. Apparently these deductions come from a federal incentive (which is a very small portion) combined with those set by the city itself. Austin is a pretty progressive city so I imagine their incentives might be a little better than most but you can call your city's general info line (3) and do a little more digging. Another option you might have is renting the equipment. I was told yesterday that a company here in town would allow for the installation and use for a monthly rate. I know how tight cash can be in school and 7 thousand might not be tangible. The whole issue of energy conservation is so prevalent these days that new info is constantly coming out. Give your current energy provider a call and see what they can tell ya. I hope you find something that works for you. -G
- Q: Can solar panels be installed on ground-mounted structures?
- Yes, solar panels can be installed on ground-mounted structures. In fact, ground-mounted solar panel systems are a popular choice for residential, commercial, and utility-scale projects. They offer flexibility in terms of location, orientation, and scalability, making them an ideal option for areas with limited roof space or shading issues. Ground-mounted structures can be customized to optimize solar panel angles for maximum energy production and are easier to install and maintain compared to rooftop systems.
- Q: I want to also know if the 0 watt rating on the solar panel is 0 watts per day or is it constantly adding 0 watts? Is there a time which the 0 watts is being added like 0 watts per second or 0 watts per minute and so on?
- You need more panel because it will take more than ones worth of sunshine to charge this battery so the battery will need to sit over night and wait to continue the charge. clouds will make the problem even worse. I use 24 - 00 Ah batteries with a 3500 watt system and I am using a 48 volt system. So my Ah = 24 X 00 / 4 = 600 Ah but this is at 48 volt so the watt hours are the same. But My computer puts the power where it is needed automatically. You have 25 watts for at best 0 hours per day = 250 Watt hours per day. That battery needs at least 200 x 2 = 2400 watt hours that does not take efficiency of any of the systems into account. As you can see this battery may never charge completely.
- Q: can you buy single solar panels say to power a washing machine fridge etc.if so where can i buy them from
- Electicity okorder
- Q: Can solar panels be used in areas with high levels of pollution from transportation?
- Yes, solar panels can be used in areas with high levels of pollution from transportation. While pollution may have some impact on the efficiency of solar panels, they can still generate electricity even in polluted environments. However, regular maintenance and cleaning may be required to ensure optimal performance and prevent any potential buildup of pollutants on the panel surface.
- Q: Can solar panels be used in areas with high levels of electromagnetic interference?
- Yes, solar panels can be used in areas with high levels of electromagnetic interference. However, proper precautions and shielding techniques need to be implemented to minimize any potential impact on the performance of the solar panels.
- Q: Can solar panels be installed on a data storage facility or server farm?
- Yes, solar panels can be installed on a data storage facility or server farm. It is a viable option to harness renewable energy and reduce the carbon footprint of these energy-intensive operations.
- Q: i have a fountain system that has a small electric pump. its made to be close to a house but i want it across the driveway and i dont want to run electrical over there.is there a small solar panel that i can get fairly inexpensive to mount on a nearby tree and be able to plug the pump into it?
- You will need more than a small solar panel to run a pump continuously, unless you don't mind that the pump only comes on during the day while the sun is out. st you need to know what the power demands are of the pump in question. Not only do you need to know the rate of the power draw from the pump, but you will also have to calculate how much power the pump will draw from your solar system every day. You will have to factor in that the sun doesn't shine brightly every day, of course there's also night, so you will need a storage battery, charging system to go along with your solar panel. Now most pumps like the one you described are 20vac. Most solar panels, the batteries, the chargers are 2vdc. In order to get 20vac you will need an inverter. Once again, you will have to make sure that the inverter you get can handle the demands of the pump. A solar system that actually works for you takes some carefull planning, it's not something that you can just hang from a tree. None of what I just descibed will be inexpensive by my definition, so if it were me, I'd dig a trench across the driveway, install some direct bury cable on a GFCI circuit out of my main power panel save a bundle.
- Q: how the energy of load connected to solar PV measure.?Want too the basic idea about it.The role of current flowing thrugh the load?Can u explain with example..can explain simply?Im not an electrical student so explain very basics
- A solar panel is made up of solar cells. Each cell produces about 0.5 to 0.6 volts. Cells are connected in series, like the batteries in a flashlight. Enough cells are placed in series to produce the desired voltage. Cells produce very little current, so many strings of cells are connected in parallel to produce sufficient current. The output is direct current (DC), like that from a battery. A home solar system needs alternating current (AC), so an inverter is used to change from DC to AC. Some systems have batteries for backup power. In these some of the DC output is used to keep the batteries charged. Systems are measured in kilowatts. System sizes are chosen to meet the demands for electricity. My system has a 6 kilowatt (kW) rating. The true output is more like 4. Now that you know this much you can Google SOLAR SYSTEMS to learn more.
- Q: Heard you can put solar panels on laptops Anyone know if it can work on a Dell mini 0v? I've seen he USB slot solar pana but can someone tell me where to gt these?
- That strikes me as completely impractical for most circumstances. The power output of your mains adapter is 30W and to do that you are looking at at least five or six square feet of solar panels costing in the region of $600 even from a surplus supplier I know. You could do it cheaper (maybe $50 on panels) but then you would be looking a more primitive panels and need perhaps thirty square feet of solar panels. This is a completely different exercise to creating a solar powered USB charger - the power requirement is a lot higher. Astronomy and space?
