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: What is the difference between solar panels and light panels?: The highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.

Q: if i have a 0 Watt solar panel what does that mean. does that mean it will charge a battery 0 watts per hour? Lets say i hook this up to a car battery and use the car battery to run computer stuff. How much will this charge the battery?: It will be less than a trickle charger on the battery. It is about .85 amps at 2 volts dc.

Q: Can solar panels be installed on schools or universities?: Yes, solar panels can definitely be installed on schools or universities. In fact, many educational institutions are increasingly adopting solar energy as a sustainable and cost-effective solution to meet their electricity needs. By installing solar panels, schools and universities can reduce their carbon footprint, save money on energy bills, and provide a valuable educational opportunity for students to learn about renewable energy.

Q: If a solar panel has a power rate of 80 Watts and efficiency of lets say 30%. Does that mean the maximum power this solar panel can generate is (30/00)*80=54 Watts or its just 80 Watts?: If it says STC or Standard Test Conditions on the nameplate or documentation, then that means 80 watts under bright sun at an unrealistically cool temperature. It is rare to see that power in real life, except when the perfect storm of conditions come together. There is also a PTC rating for some panels, which is more realistic. If the panel does not say STC or PTC, the manufacturer is free to make up whatever test they feel like, which generally leads to ridiculously overstated power. As for efficiency, for residential panels, that's generally only of academic interest. A 80-watt panel is 80 watts, regardless of the efficiency. A more efficient panel will take up slightly less space, but most people are more interested in the total price, since roof space is generally not an issue.

Q: Hi! I bought a Coleman 2 vdc cooler that pulls 9 amps. What size solar panel and amp-hour battery do I need? I only open it 3 times a day. It will hold about 3 gals of milk.: If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK

Q: Can solar panels be installed on a fire station or emergency services building?: Yes, solar panels can be installed on a fire station or emergency services building. In fact, many fire stations and emergency services buildings have embraced solar energy as a sustainable and cost-effective solution. Solar panels can help these facilities generate their own electricity, reduce utility bills, and lower their carbon footprint. Additionally, the availability of rooftop space on such buildings often makes them suitable for solar panel installation.

Q: Can solar panels be installed on a shopping mall or retail complex?: Yes, solar panels can be installed on a shopping mall or retail complex. Many shopping malls and retail complexes have large roof spaces that can accommodate solar panels. Installing solar panels on these buildings can help to reduce energy costs, decrease carbon footprint, and demonstrate a commitment to sustainability. Additionally, the solar panels can provide a source of clean and renewable energy to power the operations of the shopping mall or retail complex.

Q: Can solar panels be installed in areas prone to hurricanes or tornadoes?: Yes, solar panels can be installed in areas prone to hurricanes or tornadoes. However, it is important to design and install the solar panel system with the specific weather conditions in mind. This includes using appropriate mounting systems, ensuring proper anchoring and reinforcement of the panels, and using high-quality materials that can withstand strong winds. Additionally, regular maintenance and inspections should be conducted to ensure the panels remain in optimal condition.
