FAQ1
We have organized several common questions for our clients，may help you sincerely：
1.What price for each watt?
It depends on the quantity, delivery date and payment terms,
2.How do you pack your products?
We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.
- Q: I heard that solar energy has a lot of advantages but are there any drawbacks in using the solar panels?
- The major drawbacks are the high cost with low power payback. Also, the sun isn't shining for a good share of the time. life span is 20-30 years and then you have to spend the money all over again. It's cheaper to use public utilities for power, but not as green.
- Q: Can solar panels be installed on theme parks or entertainment venues?
- Yes, solar panels can be installed on theme parks or entertainment venues. In fact, many theme parks and entertainment venues around the world have already embraced solar energy as a sustainable solution to power their facilities. Solar panels not only provide a clean and renewable source of energy but also contribute to the overall theme park or entertainment venue's commitment to environmental conservation.
- Q: what direction should solar panels face to get the best exposure of the sun.
- depends on the exposure.[trees other buildings, etc.] If you don't have trackers to keep the panels facing the sun , just plain old due south ,I've heard, is best for best average exposure.
- Q: Are solar panels weatherproof?
- Yes, solar panels are designed to be weatherproof and can withstand various weather conditions such as rain, snow, hail, and wind. They are made with durable materials and have protective coatings to ensure long-term performance even in harsh climates.
- Q: If you buy everything you need for a grid-tied solar set up, can you install it yourself or is it required that a professional installs it?
- Solar panels have to be installed by a professional in order to get the government rebates. Also the systems must meet state and local electrical codes. Most modern inverters will not turn on unless there is live power from the MAINS, so a ultility company is NOT required for any installation anywhere. There are plenty of electrical contractors and speciality solar contractors out there to help you to make sure that the system is properly designed with the correct components, properly installed, and legally certified. Also many states require a permit that may have a large fee before any installation and may not allow the homeowner, especially for city homes, so it is best to check first. You might be able to get away with it if you live in the country, but consider the safety as well. See if you can work with your contractor to get the materials that you both agree upon as well. They can help guide you based upon their experience. Also shop around for pricing as the panels are now going below $ per watt !
- Q: how to use a motor with solar panel
- You really need to read up on some basic electricity before you begin this experiment. The voltages and current requirements of the motor as well as the supply all come into play
- Q: I was just wondering what the minimum and maximm charging voltage and ampere is for li ion batteries. If i connect a solar panel, which only gets enough sunshine to generate voltage, will that still charge the battery, or would i have to series connect solar panels until they together reach 3,7volt?
- One lithium cell requires 4.2V to obtain its full charge, Never exceed 4.2V ! Output from solar panel if below 3.7V , nothing charge to lithium. Total charging time until the cell is full depending on the AH rate of cell and the charging current that solar panel can be provided. Suppose cell is rate 5AH, and the charging current from solar panel under full sun shine can maintain 0.5A ( use solar panel short circuit current rate from its specification as a reference ) , hence, 0 hours is enough. And be sure the solar panel can maintain 4.2V output at 0.5A . Remember, over charge lithium cell one time might reduce its life into half . Therefore, let the solar panel output passing through a precision regulator to maintain output is 4.2V is the best way, because, as cell reaches 4.2V , no more charging current is forced into cell ( automatic stop charging ). If you do not have the knowledge to make this simple variable voltage regulator with LM37K ( if you choose this way, buy solar panel output has at least 2V) , you may choose to do it manually by install a current meter and a variable resistor in series between the panel output to cell. By adjust the value of resistor, charging current can be controlled ( if you choose this way, buy solar panel output has as less as 6V ). Count the charging time with a clock and adjust the charging current from time to time to maintain 0.5A .
- Q: My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx
- 2.20 approximatey (2 /4 -- ish) X = (tan7)(8/tan45)
- Q: i am very much interested in making a solar panel, my problem is where i can acquire the main components in order to build it, i am staying here in abu dhabi UAE i'm always searching on the internet for shops that can provide me a DIY kit but i did not find one, i need somebody who knows where i can get these things, please let me know.
- Have okorder . This can immediately instruct each and every one!
- Q: Are there any risks associated with solar panel installation?
- Yes, there are a few risks associated with solar panel installation. Some potential risks include the risk of falling during installation, electrical shock or fire hazards if not installed correctly, potential damage to the roof during installation, and the risk of panels not performing as expected due to factors like shading or poor maintenance. However, these risks can be minimized by hiring a professional installer, following safety guidelines, and ensuring proper maintenance and monitoring of the solar panel system.
