- Q:how much would you pay for a 2'x4' solar panel that puts out 24 volts and 74 watts?
- That's a rather low power for that size. Is it an old panel? Is it amorphous silicon, or crystalline? That should easily fetch $ per watt on craigslist. If I was buying a panel myself, I would probably get a more mainstream panel from a major internet vendor.
- Q:If I put a 5000 watt solar panel kit on my roof in Dublin (Ireland) - how much electricity would I realistically expect to get?An educated guess at a percentage of 5000w would do.
- Note that aiming is important - the sun is going to be perpendicular to the panels for only a few hours a year unless they are on an adjustable mount, so picking the time you most want power should be a factor in the angle they are mounted at - you can't keep the highest level of sun for summer into the winter time when the sun is much lower in the sky for a shorter time.
- Q:Can solar panels be used to power an entire office building?
- Yes, solar panels can be used to power an entire office building. By installing a sufficient number of solar panels on the roof or in a separate solar farm, it is possible to generate enough electricity to meet the energy demands of an office building. Additionally, advancements in solar panel technology and energy storage systems make it more feasible to rely solely on solar power for an office building's energy needs.
- Q:I'm looking to see how much it would be to install solar panels on a home. Or more information on where i would be able to locate a place of purchase, or in general more information...
- Let your fingers do the work and look up a solar company in your phone book. If and when you find one consider a thermosiphon solar hot water heater. The cost is dependent on the number of people using it.
- 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:Ok so i have to solar panels to charge a battery however the panels hooked up in series does charge the battery very slowly because series connections only multiplies the voltage but leaves the current the same. Is there a way i can also hook both of them up in parallel at the same time to multiply the current for faster charge? I know i can do this with 4 panels but i dont want to spend extra. So is there a way to hook up 2 solar panels in series and parallel at the same time? Thanks in advace
- No. You can only hook them up as one or the other. Attempting to do both would simply short circuit the panels and you'd get no output at all. Your panels should produce an open circuit voltage in full sun that is almost twice the voltage of the battery you want to charge (it's because solar panels produce the most power at their maximum power point, which is usually about 60% of the open circuit voltage). If a parallel connection does that, then use it, otherwise you'll need to use series. You didn't say what the capacity and voltage of the panels or the size of the battery was. It's quite possible you don't have enough panel - you need panels that will put 5% (at least) of the ampere hours capacity of the battery in as current. For example, if you have a 00 amp-hour battery, you'll need enough panel to put 5 amps in at the voltage of the battery. DK
- Q:Do solar panels require direct sunlight to work?
- No, solar panels do not require direct sunlight to work. They can still generate electricity from indirect sunlight or even on cloudy days.
- Q:Can solar panels be installed on museums or cultural centers?
- Yes, solar panels can be installed on museums or cultural centers. In fact, many museums and cultural centers are embracing solar energy as a sustainable and cost-effective solution for their energy needs. By installing solar panels, these institutions can reduce their carbon footprint, lower energy costs, and demonstrate their commitment to environmental stewardship. Additionally, the installation of solar panels on such iconic buildings can serve as a visual representation of their dedication to renewable energy, inspiring others to follow suit.
- Q:Can solar panels be used in areas with high levels of electromagnetic radiation?
- Yes, solar panels can be used in areas with high levels of electromagnetic radiation. However, it is important to ensure that the panels are properly shielded and grounded to minimize any potential interference or damage caused by the electromagnetic radiation.
- Q:How does the size of a solar panel affect its performance?
- The size of a solar panel directly affects its performance as it determines the amount of sunlight it can capture and convert into electricity. Generally, larger solar panels have more surface area to absorb sunlight, resulting in higher power output. A larger panel can generate more electricity, making it more efficient and productive than a smaller one. Additionally, larger panels often have more individual solar cells, which further enhances their performance and efficiency.
