- Q: I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?
- At present the technology to create silicon solar cells is incredibly energy intensive. It is not logical to compare the cost of oil to the cost of a solar cell because they are not priced according to energy input. Oil has a strong advantage in that it is concentrated solar and geothermal chemical energy that has accumulated over millions of years. The price of oil does not reflect its energy content, but the cost to retreive it. Electrical energy used to produce a Photovoltaic cell is not priced in any proportion to oil. By some calculations it will take about 50,000 KWh of energy produced by the PV cell before it can recover the energy used to manufacture it.
- Q: Can solar panels be installed on a concert venue or entertainment facility?
- Yes, solar panels can be installed on a concert venue or entertainment facility. Solar panels can be mounted on rooftops, parking lots, or even integrated into the design of the venue itself. These installations can help offset the energy consumption of the facility, reduce carbon emissions, and potentially save on electricity costs in the long run.
- Q: For my exam in science we are required to make a power point explaining why it would be good for our school to switch to solar. our complete handout given to us by our teacher is as follows:Power Point to include:. What you propose for alternative energy usea. Any thoughts on energy conservation...2. Why this is a good idea3. What information you would give the solar company (area of roof space your group determined to be useable for solar)In PowerPoint - include your quot;scriptof what you would be saying when the slide is up in the Notes section below the slideANY HELP WOULD BE GREATLY APPRICIATED!!THANK YOU SO SO MUCH,QH
- Energy conservation Use sensors that turn of lights and unneccassary equipment when person leaves the premises 2) Saves hard earned energy 3) Area of roof space depends on how much energy you want to collect from the sun.
- Q: Why can not the solar panel load directly?
- Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
- Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
- If the panels are the same, there is no problem in putting them in series. If you examine the panels, they will be made up of about 36 identical cells in series. Ok, now you have 72 cells in series, fine if they are the same. You need (at a minimum) a diode in the line so that when it is dark, the panels do not draw current out the batteries (it wont be much but you might as well block it). You say the panels are rated 5 amps? Those are pretty good sized panels! Unless you have a charging regulator, I guarantee that they Will overcharge the batteries (unless the batteries are huge, like the size of a refrigerator). Did you maybe mean 5 watts? About a foot square? If so, the output is about 300mA (0.3 amps) which will not overcharge a battery as long as it is at least as large as a garden tractor battery. At a 300mA charge rate, it will take a longgg time to recharge.
- Q: What is the lifespan of solar panel batteries?
- The lifespan of solar panel batteries can vary depending on various factors such as the type of battery, its quality, and usage patterns. Generally, solar panel batteries are designed to last between 5 to 15 years. However, with proper maintenance and care, some batteries have been known to last even longer.
- Q: I need a solar panel which can light up 4 full loaded 5 rooms appartment houses
- good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
- Q: Can solar panels be installed on historic buildings?
- Yes, solar panels can be installed on historic buildings. However, the installation process may require careful planning and consideration to ensure that the panels are discreetly integrated with the building's architecture and do not compromise its historical value. In some cases, solar panels may need to be installed in less visible areas or designed to resemble traditional building materials. Additionally, it is important to consult with preservation experts and local authorities to ensure compliance with any regulations or guidelines specific to historic buildings.
- Q: Can solar panels be installed on a community center or social gathering place?
- Yes, solar panels can be installed on a community center or social gathering place. Solar panels are versatile and can be installed on various types of buildings, including community centers, to harness solar energy and reduce dependence on traditional energy sources. This can help make the community center more sustainable, reduce its carbon footprint, and potentially save on energy costs.
