Why choose our solar panel is you ideal choose?

1. The important raw material, Solar cells, come from domestic public company and Taiwan famous company. Quality assurance: 25 years long life span, Industry leading power output warranty 10 years 100%, 20 years 95%, 25 years 85%.

There are some company which select inferior solar cells that are processed from recycled silicon material from small workshop, so their solar panel service life maybe less than 5 years because inferior solar cell power reduce much more every year.

2. Our company has automated production line for solar panel. Good technology, good quality assurance. Strong production ability: 300 pieces 300w solar panels can be manufactured per day. Most of company weld solar cell with artificial manual work. Bad manufacturing technique is difficult to keep consistency of products.

Q: Do solar panels require maintenance?: Yes, solar panels do require some maintenance. Regular cleaning to remove dirt and debris is necessary to ensure optimal performance. Additionally, checking for any signs of damage, such as cracks or loose connections, is important. Routine inspections and occasional repairs or replacements may be needed to keep the solar panels functioning efficiently.

Q: Are there any maintenance requirements for solar panels?: Yes, solar panels do have maintenance requirements. While they are generally low maintenance, they need to be kept clean and free from debris to ensure optimal performance. Periodic inspections for any damage or shading issues are also recommended. Additionally, the electrical connections and inverters may require occasional maintenance or servicing.

Q: Can solar panels be installed on desalination plants?: Yes, solar panels can be installed on desalination plants.

Q: How do solar panels affect the property's energy resilience?: Solar panels can greatly increase a property's energy resilience by generating clean and renewable electricity on-site. By harnessing the power of the sun, solar panels provide a reliable source of energy that can offset or even eliminate the need for grid-supplied electricity. This reduces dependence on fossil fuels and the vulnerability to power outages or price fluctuations. Additionally, solar panels can often store excess energy in batteries, allowing for uninterrupted power supply during emergencies or blackouts. Overall, solar panels contribute to a more resilient and self-sufficient energy system for the property.

Q: There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?: Good question. One of the reasons is the greed of manufacturing companies. No matter the profit margin of the product, they seem to want to charge so high a price that the break even point is ten years down the road, so the true savings are few. The cost of solar panels should have dropped way lower than they have by now. I believe that the political correctness of the product will tempt the manufacturers to keep the prices artificially high. One other answerer is right, the panels are very fragile, and damage would destroy the investment, so new inroads need to occur in technology to protect the panels from damage. Somewhere in the middle is a profit for the manufacturers, and savings for the consumer. I hope we find that middle-ground soon.

Q: Can solar panels be installed in urban areas?: Yes, solar panels can be installed in urban areas. In fact, urban areas provide great opportunities for solar panel installations due to the abundance of rooftop space and potential to generate clean energy in densely populated areas.

Q: Can solar panels be used to power a zoo?: Yes, solar panels can be used to power a zoo. Solar panels can generate electricity by converting sunlight into energy. This renewable energy source can effectively power various operations within a zoo, including lighting, heating, cooling, and powering animal enclosures, as well as other facilities such as gift shops and food stands. By utilizing solar panels, zoos can reduce their dependency on fossil fuels, lower their carbon footprint, and contribute to a more sustainable and environmentally friendly operation.

Q: I was trying to look online for solar panels for my home to take some of the strain off of using oil and electricity but I find it very hard to understand exactly how they are used.Like one that I looked up is 00 watts.....is that like a light bulb watt? How many things can that power? Is it really cheaper in the long run because the panels are very expensive?If anyone has web sites that can explain this to me I would appreciate a link, or anyone to answer part of my question.: I okorder Hope this helps.

Q: I am looking at a need of roughly 30w/hour need per 24 hour period. I have spent several hours now looking for information online and have found plenty of info regarding the panels themselves, but information regarding the batteries backups have been slim. I understand that there is a 5-7 hour peak time to collect the energy. I am looking for information regarding the batteries themselves. How do the batteries work, what size batteries should I look for, and what is the life expectency for the batteries? Any website links would also be appreciated!: Solar panels have their own characteristics and generate current depending on the intensity of sunlight falling on them and not on the temperature. Direction of the panel also makes lots of difference. Nowadays very thin panels are available at very high cost. The more area a panel occupies it generates more current. The current generated by a panel cannot be readily used since the current and voltage varies with the load connected to it. So normally a regulator is used to have constant voltage and constant current to come from the panel. This charges the battery. You have to calculate the total/normal current from the charger and then find the AH of the battery. When you have calculated the AH of the panel/charger then you can divide the AH of the battery by the AH of the charger/panel and find out the time taken to fully charge the battery. You also have to remember that there is a de-rating factor to be taken into consideration in the battery.

Q: How do solar panels affect the roof's integrity?: Solar panels can have a positive impact on a roof's integrity. By acting as a protective layer, solar panels shield the roof from various weather elements, including harmful UV rays, hail, and debris. Additionally, they can help to extend the lifespan of the roof by reducing exposure to extreme temperatures. However, it is crucial to ensure proper installation by professionals to avoid any potential damage or leaks.
