FAQ:

1. What's brand of this solar panel?

Answer : Soular solar. We are the manufacturer of this panel, OEM service is available, wholesales is welcome.

2. We need your pricelist for all the models ?

Answer : we dont present "pricelist" for a new customers, Because different order quantity, different  quality grade has different pricelist; right now, we can produce  solar panel from 3w to 300w for both poly & mono panel.

Attn. : You can just inform us your "target price" and detailed requirement , we will evaluate if we can produce for you.

3 . Our common questions for the new customer's inquiry :

(1) How many pcs solar panel do you need ?

(2) Which type do you need, Poly or Mono ?

(3) What is your requirement on the power, Voc, Isc, Vm, Im ?

(4) Which transportation way will you select ? by air ? by Sea ?




Q: The voltage and power problems of solar panels
In general, the charging voltage is 1.5 times the battery voltage as well, that is 12V battery pack, select the 18V solar panels just.
Q: Can solar panels be installed on residential complexes or apartment buildings?
Yes, solar panels can be installed on residential complexes or apartment buildings. In fact, they are increasingly being installed on such structures to harness clean and renewable energy for multiple households. The installation process typically involves placing the panels on rooftops or in open spaces within the complex, allowing residents to benefit from reduced electricity costs and a more sustainable living environment.
Q: When you add a load resistor to a PV panel (Solar panel) of 00 ohms what happens to the voltage produced from the cellAlso, as the resistance increases, how does this affect the output voltage
Look at the graph data that looks like a rotated L. That is what voltage as a function of current characteristically behaves. The highest voltage value is called open circuit voltage (Voc). The current at lowest voltage value is called short circuit current (Isc). If you notice, a second curve is plotted that looks like a hill. That curve is power output as a function of voltage. At the peak of said hill, you get the most utility of your PV module, as you output the maximum power possible, and that is the nameplate value for the PV module's power rating.
Q: Can solar panels be installed on a greenhouse?
Yes, solar panels can be installed on a greenhouse. In fact, it is a popular practice to install solar panels on greenhouses as it allows for sustainable energy production while utilizing the available rooftop space. The solar panels can help power the greenhouse's electrical systems, such as ventilation, lighting, and irrigation, reducing reliance on external energy sources. Additionally, the panels can provide shade and protection to the greenhouse, helping to regulate temperature and improve overall energy efficiency.
Q: What specification of solar panel would I need to power a laptop every day? I would need to use it for about 0 hours or so every day. I don't know anything about solar panels, but I am seriously thinking of getting one now and don't know who to ask.
You will need, A battery to store the electricity from the solar panel. The amount of electricity from the panel varies up and down as things such as clouds, position of the sun, etc. reduce the amount of solar rays hitting the panel. The battery stores it all, the ups and downs, and sends it back out at a steady voltage so you can operate your p.c. / appliance. A minimum of 45 watts solar panel. 60 watts would be preferable. 45 watts will charge a battery in one day under ideal conditions. You turn the panel as the sun moves across the sky, no clouds. 60 watts will charge a battery in one day with out moving and regardless of clouds. A controler to prevent the electricity from flowing backwards from the battery to the solar panel when the sun goes behind a cloud or sets at night and the charge drops below the voltage of the battery. A good controller will tell you the charge condition of your battery so you know when it is too low to operate your p.c. safely. And finally an inverter with True Sine Wave capability to change the electricity from the battery into usuable power for your PC and other electronics. Not all inverters produce true sine wave electricity. The electricity has static in it and will make your pc screen jump around and not function as it should. New digital T.V.'s also require true sine wave electricity to operate. Go the extra cost and get the inverter with true sine wave and be happy with the way your p.c. functions. Figure out how many Watts your p.c. or appliance will draw. and match the Inverter to the need. Do not go too big, as they cost more and consume more of your stored electricity to operate. Save as much electricity as you can. You will be able to operate your p.c. appliance longer. When not using your p.c., you can operate your T.V. or other low watt appliance.
Q: i need to make a solar panel model for a project in science and i would like to know how to build a easy model at home that wont cost alot
There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
Q: I am doing a project for school and i need to power a 9v DC motor using a solar panel. Does anyone know places i could get these for not to expensive, and how many volts/watts i would need?
Radio Shack.
Q: Can solar panels be installed on a pergola or awning?
Yes, solar panels can be installed on a pergola or awning. In fact, these structures can provide an ideal platform for solar panel installation, as they offer ample sunlight exposure and an elevated position that maximizes energy production. Installing solar panels on a pergola or awning can not only generate clean and renewable energy but also provide shade and protection from the elements.
Q: Can solar panels be used in areas with high levels of heatwaves?
Yes, solar panels can be used in areas with high levels of heatwaves. In fact, solar panels can still generate electricity in extreme heat, although their efficiency may decrease slightly due to the temperature increase. However, it's worth noting that high temperatures can also lead to increased energy consumption for cooling, which may offset the benefits of solar energy to some extent. Nevertheless, solar panels remain a viable and sustainable solution for electricity generation in areas with high levels of heatwaves.
Q: I would like to know how much a solar panel would cost for a wingspan of 208 ft for a plane
2,000 that we have used 4 project , its based on the cell size
