5.FAQ of Solar Module

1. Q: Do you have your own factory?
    A: Yes, we have. Our factory located in Jiangyin city, jiangsu province.
2. Q: How can I visit your factory?
    A: Before you take off from your country, please let us know. We will show you the way,or arrange time to pick you up if possible.
3. Q: Do you provide free sample?
    A: Usually we do not offer free sample
4. Q: Could you print our company LOGO on the nameplate and package?
    A: Yes, we can do that.
5. Q: Do you accept custom design on size?
    A: Yes, if the size is reasonable.

Q: How do solar panels interact with the electrical grid?: Solar panels interact with the electrical grid through a process called net metering. When solar panels produce more electricity than is being used, the excess power is sent back to the grid, and the owner is credited for the energy produced. Conversely, when solar panels don't generate enough electricity, energy is pulled from the grid to meet the demand. This bidirectional flow enables solar panel owners to offset their energy usage and contribute to the overall energy supply.

Q: Can solar panels be installed on an RV or camper?: Yes, solar panels can be installed on an RV or camper. This allows you to harness the power of the sun to generate electricity and charge your batteries, making your RV or camper more self-sufficient and reducing reliance on traditional power sources.

Q: How often do solar panels need to be replaced or repaired roughly? Is it costly to do so?: New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link

Q: Can solar panels be used for powering water treatment plants?: Yes, solar panels can be used for powering water treatment plants. Solar energy can be harnessed through photovoltaic panels to generate electricity, which can then be used to power the various processes involved in water treatment plants. This renewable energy source offers a sustainable and environmentally-friendly solution for powering water treatment facilities.

Q: If you were to be asked to write a material(s) report on either -solar panelsor -aircraft fuselageWhich would you choose?well i was asked to choose between these two,so i guess that if i choose what the majority wouldn't, i might just score a little bit higher,what do you think?if you are the lecturer you would want something different right?: Aircraft fuselage. Right now solar panels are all the rage, and there's lots and lots of nonsense written about them. Aircraft design is old technology, but still quite fascinating. Learn about riveting and gluing techniques, the various aluminum alloys or plastics used, and compare the weight of an airplane fuselage with that of a building of comparable size.

Q: I'm curious, for those who have had solar panels installed on the rooves of their houses:How much did you pay? How much energy do the panels produce? Did it dramatically cut down on your electricity bill? Was it worth it? Thanks!: No, but if you have the money, go for it. In Germany, people get a government rebate (much like the Prius rebate our own government offered) and so you see solar panels everywhere. If the Obama administration pushes for a rebate for solar panels, you will see them here in the state. It's the initial cost that puts off most potential solar panel customers. Upkeep isn't too expensive, and they ultimatley pay for themselves. (after about a decade)

Q: How long does it take to recoup the cost of solar panels through energy savings?: The time it takes to recoup the cost of solar panels through energy savings can vary depending on several factors such as the initial cost of the panels, the amount of energy they generate, and the cost of electricity in your area. On average, it can take anywhere from 5 to 20 years to recoup the upfront cost. However, it's important to note that solar panels have a lifespan of 25 to 30 years, so you can continue to benefit from energy savings long after recovering the initial investment.

Q: so i told my dad to buy solar panels and he wants to see how much money u can save we pay $00 and i dont want quot;You don't need solar panelshow much would my fmaily save?: First, to answer your question we would need to know how much power you use, the solar capability of the area you live in, and several other facts.

Q: Main questions: How can I work out the efficiency of a solar panel and how can I work out if the panel is relatively cost-effective? Also what type of solar panels is considered most effiecient?Let's assume that all relative values are available.Secondary question: What type of safety regulations and licenses are required to be fulfiled in order to import solar panels into the EU from non-EU countries?: Guide okorder /

Q: What is the impact of bird droppings on solar panels?: Bird droppings can have a negative impact on solar panels as they can reduce the efficiency of the panels by blocking sunlight. The droppings can create shadows and reduce the amount of sunlight that reaches the panels, leading to decreased energy production. Additionally, the acidic nature of bird droppings can damage the surface of the panels if not cleaned regularly, potentially reducing their lifespan. Therefore, it is important to regularly clean and maintain solar panels to ensure optimal performance and longevity.
