FAQ
1. Q: Do you have your own factory?
A: Yes, we have. Our factory located in 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.
- Q:Can solar panels be used to power an emergency response center?
- Yes, solar panels can be used to power an emergency response center. Solar panels convert sunlight into electricity, providing a sustainable and reliable source of power. By harnessing solar energy, emergency response centers can ensure uninterrupted electricity supply, even during power outages or in remote areas. Additionally, solar panels are environmentally friendly and reduce reliance on traditional energy sources, making them a viable option for powering critical facilities like emergency response centers.
- Q:Can solar panels be installed on streetlights?
- Yes, solar panels can be installed on streetlights. This allows them to generate and store their own electricity, making them more energy-efficient and reducing the reliance on grid power.
- Q:Do solar panels require cleaning?
- Yes, solar panels do require cleaning. Over time, dust, dirt, leaves, bird droppings, and other debris can accumulate on the surface of solar panels, reducing their efficiency. Regular cleaning is recommended to ensure optimal performance and maximize energy generation.
- Q:How much energy can be generated from a solar panel on a clear, bright summer's day for example?
- Well, the maximum amount of energy you can receive with 00 percent efficiency is kilowatt per square meter. This is the energy that hits the Earth's surface. The best commercially available panels are 20-30 percent efficient. Cutting edge technology has gotten this percentage up to 50 percent, but you can't buy these for your home. If you're curious about efficiency, check out a panel's dimensions, find the area in square meters, and use that along with its Watts (divide by 000 to get kilowatts) to get your answer.
- Q:Can solar panels be used to power a public transportation system?
- Yes, solar panels can be used to power a public transportation system. By installing solar panels on the rooftops of public transportation vehicles or on charging stations at transit hubs, the energy generated from the sun can be harnessed to provide power for electric buses, trams, or trains. This reduces reliance on traditional energy sources and helps to make public transportation more sustainable and environmentally friendly.
- Q:Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?
- I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.
- Q:I have seen quite a few different websites that talk about building your own solar panels for around $200. I wanted to know if anyone has had any experience with this before I decide to try it myself. It would be very helpful to know what I can expect from such an inexpensive setup; what kind of electronics or appliances would I be able to power. Realistically what can I expect from a $200 setup, and what would I need to power say a whole bedroom (clock, regular sized TV, PC, ext.).
- Scam. okorder / Many of the other review sites are fakes to steer people into buying.
- Q:Can solar panels be installed on a historic building?
- Yes, solar panels can be installed on a historic building. However, it is important to carefully consider the impact on the building's aesthetics and historical integrity. Specialized techniques and materials may be required to ensure that the installation is done in a way that preserves the building's unique architectural features. Additionally, it may be necessary to obtain permission or meet certain requirements from local historic preservation authorities before proceeding with the installation.
- Q:Does the new horizons has a solar panel for it power resources instead using nuclear generator?
- No solar panel, and for the reason you stated - it is so far from the Sun that a solar panel would be of little use (and a lot of extra weight) at the distances where the primary part of the mission was being performed. The power source is called an RTG. We can think of it as similar to a nuclear-powered battery or a miniature nuclear power plant. As far as I know it is not intended to reach any other star. If it does, it's power will have long since depleted - and it would take thousands of years at its current speed to reach even the closest star. Closest star: Proxima Centauri, slightly more than 4 light years away. Current speed of New Horizons relative to the Sun: 4.52 km/s That's 0.000048 of the speed of light. It would take more than 20,000 years to reach Proxima Centauri *if* it were heading in that direction (which it is not).
- Q:Can solar panels be used in areas with high levels of chemical pollutants?
- Yes, solar panels can be used in areas with high levels of chemical pollutants. However, frequent maintenance and cleaning may be required to prevent the accumulation of pollutants on the panels, which could reduce their efficiency over time. Additionally, the presence of chemical pollutants in the air may have a negative impact on the overall performance and lifespan of the solar panels. Therefore, it is important to assess the specific conditions and potential risks before installing solar panels in such areas.
