FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What is a solar PV module?

A: A solar PV module consists of many solar cells that are connected together (typically in series) and packaged in a frame (typically made of aluminum).

Q3: What are the advantages and disadvantages of monocrystalline solar PV modules?

A: Monocrystalline solar PV modules are the most efficient type of solar PV modules, with the exception of CdTe thin film solar PV modules. As a result, monocrystalline solar PV modules are more expensive when compared to almost all other types of solar PV modules.

 

 

 

Q:How do I clean my solar panels?
To clean your solar panels, start by turning off the system and ensuring the panels are cool to touch. Use a soft brush or sponge with mild detergent mixed in water to gently scrub away any debris or dirt. Rinse the panels with clean water and allow them to dry naturally. Avoid using abrasive materials or harsh chemicals, as they may damage the panels. Additionally, be cautious when working at heights and consider seeking professional help if needed.
Q:Can solar panels be installed on asphalt shingles?
Yes, solar panels can be installed on asphalt shingles. However, it is important to ensure that the shingles are in good condition and can support the weight of the panels. Proper installation techniques and mounting systems designed for asphalt shingles should be used to prevent any damage to the roof.
Q:Can solar panels be used for charging outdoor power tools?
Yes, solar panels can be used for charging outdoor power tools. They can harness sunlight and convert it into electricity, which can then be used to charge the batteries of outdoor power tools. This allows for a sustainable and convenient way to power these tools without relying on traditional electricity sources.
Q:Where can I buy solar panels other than online in Charlotte, NC?
Do a web search for solar panels Charlotte NC.
Q:Can solar panels generate electricity at night?
No, solar panels cannot generate electricity at night because they rely on sunlight to produce energy.
Q:I am starting to think about solar panels as an option for my home. I have done some research on panels, to be honest its all very confusing. There are many different panels some with 60 watts some all the way up to 20 watts. My household currently uses about 2700 to 3400 kWh every two months. So based off of my power usage maybe you can answer some of the following questions:What kind of panels should I be looking at?Which panel manufacturers give the best bang for the buck (reliable/affordable)?Anything else I should be concerned about?I am just starting out in educating myself on solar power so please excuse me if I sound very naive. Any information that you may have will be helpful. Thanks in advance.
Unfortunately, I can't give you a lot of specifics on what you should use. However, I can tell you that the very best system for you simply might not be available to you, in which case it really doesn't matter how good it is. Your best bet would be to talk to a supplier in your area and see what is available, THEN start looking at the differences between those. Unfortunately, solar panels aren't quite to the point of being a common-place product...yet. Another thing to consider would be how old your roof is. You might want to look into the possibility of building-integrated materials if you are in need of a new roof. Talking with somebody who sells the panels in your area will help you understand a lot more than just doing raw research. Get their take on it, then fact check and research what they tell you so you know you're not getting ripped off.
Q:What is the principle and structure of solar panels?
inverter: solar direct output are generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC appliances, it is necessary to convert the DC power from the solar power system into AC power, so it is necessary to use DC-AC inverter.
Q:If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?
Solar panels are rated under standard test conditions (STC), a certain amount of light at a certain distance, at a certain temperature, etc. A kW, or kilo watt, is 000 watts. So for the amount of time that the sun meets those conditions, the rate of output is 500 watts. An average location has an average of 5 sun hours a day, the total time that you produce the rated output. Watts is a rate, like miles per hour (mph), how fast it is going. Watt hours, or kilo watt hours (kwh) is a quantity, like miles. So if you drive 50 mph for 5 hours, you went 250 miles (50 mph x 5 hours). If you produce .5kw for 5 hours, you have the potential to produce 7.5kwh a day. Multiply that by 30 days in a month, you get 225kwh a month. In reality you will lose about 30% of the rated power from less than ideal weather, system losses, etc., so it's more like 50kwh a month. You can look at your electric bill to see how many kwh you use a month, maybe around 000kwh, and see what percentage of your usage a system like that can power.
Q:Can solar panels be installed on rooftop gardens or green roofs?
Yes, solar panels can be installed on rooftop gardens or green roofs. In fact, these locations can provide an ideal setting for solar panel installation as they often receive ample sunlight due to their elevated position and minimal shading. Additionally, the vegetation and greenery on these rooftops can help with temperature regulation and improve the overall efficiency of the solar panels.
Q:What is the typical warranty period for solar panels?
The typical warranty period for solar panels is around 25 to 30 years.
