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:I have a 500 watt inverter and battery but need solar panels to run my need. I want to have enough juice to run a computer and monitor and sometimes a 5w amp. I am not sure how much power is needed to run the computer (standard desktop with 5flat screen with an additional surround sound system) though on the side of the computer it says 5 amp but I know I used to run it and monitor and surround sound with a heating blanket on the same circuit which was rated at 20 amps. My question is that I would like to go and buy some panels (cheaply as I'm unemployed) from somewhere like Harbor Freight that would meet the need of the converter to supply enough amperage. So what size panel(s) or panels would I need to run this setup? If I am correct I think 500 watts is equal to 5 amps. Would this even work? Could I run a partial system where I could run some of the stuff to take a load off? I need to lower my electric bill somehow. Thanks!

Q:Can solar panels be installed on a shaded roof?
Yes, solar panels can be installed on a shaded roof, but their efficiency may be significantly reduced. The amount of shade and its duration throughout the day will determine the impact on energy production. It is recommended to assess the roof's shading factors and consult with a solar panel installer to determine the feasibility and potential output of a shaded installation.
Q:Can solar panels be installed on a university or college campus?
Yes, solar panels can absolutely be installed on a university or college campus. In fact, many educational institutions have already embraced solar energy and installed solar panels on their campuses. These panels can be placed on rooftops, parking structures, or open spaces to generate clean and renewable electricity. Installing solar panels not only helps reduce the environmental impact of the campus but also provides educational opportunities for students to learn about sustainable energy practices.
Q:Can solar panels be installed on a convention center or event venue?
Yes, solar panels can be installed on a convention center or event venue. In fact, many convention centers and event venues are increasingly adopting solar energy solutions to reduce their carbon footprint and lower energy costs. The large roof spaces available in these venues often make them ideal for solar panel installations, allowing them to generate clean and renewable energy.
Q:Are there any safety precautions to consider when installing solar panels?
Yes, there are several safety precautions to consider when installing solar panels. Firstly, it is important to ensure that the area where the installation will take place is free from any potential hazards, such as loose debris or electrical cables. It is also crucial to follow proper electrical safety procedures, such as turning off the power supply before starting the installation and using appropriate personal protective equipment. Moreover, working at heights can pose risks, so it is essential to use proper equipment like safety harnesses and scaffolding when necessary. Lastly, it is recommended to consult with a professional or an experienced installer to ensure compliance with local building codes and safety regulations.
Q:I have an off-grid 24volt existing system using 8 x 80 watt 2volt, wired at 24volts, mono solar panels with deep cycle batteries,operating now. I have been given a 240 2volt polly cryst. panel. Can I add this panel to existing panels as above. Thank you, dumb solar man
Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
Q:How do solar panels affect home resale value?
Solar panels can increase the resale value of a home due to their potential cost savings and environmental benefits. Studies have shown that homes equipped with solar panels tend to sell faster and at higher prices compared to similar properties without solar installations.
Q:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:How much roof space is needed for solar panels?
The amount of roof space needed for solar panels varies depending on various factors such as the size and efficiency of the panels, the energy requirements of the building, and the geographical location. However, on average, a typical residential solar panel system requires approximately 100 to 400 square feet of roof space.
Q:Can solar panels be used to power a mining operation?
Yes, solar panels can be used to power a mining operation. Solar energy can be harnessed and converted into electricity to meet the power needs of a mining operation. By installing a solar panel system, mining companies can reduce their reliance on fossil fuels, lower energy costs, and minimize their carbon footprint. However, the feasibility of using solar panels for mining operations would depend on various factors such as the energy requirements of the mine, available sunlight, and the size of the solar panel system needed to generate sufficient power.
