3.Usage and Applications of Poly Cells

Solar cells are often electrically connected and encapsulated as a module.

Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage.

Connecting cells in parallel will yield a higher current;our solar cells have passed IEC Certification.

With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

Q: Ok Im trying to power my room using solar panels and I've figure out that I need about 700 watts to do so, but I really only use my electronics at night. I was wondering if I could buy lets say a 200 watt solar panel and let it charge a battery all day would that work? I live in southern california so I dont have to worry to much about cloudy days. also any suggestions on where to buy a panel, inverter, charge regulator, and battery?: You have to look carefully at your battery choice. If you use lead-acid, use only the sealed type. Then you need to select a battery charger that is tailored to that battery type. If you want to run 700 watts for 6 hours, that is 0kwhrs. A 200 watt panel will take 50 hours to charge that, probably more like 70 to allow for losses. Even is S CA you don't get 70 hours of sun per day. Even for 3 hours of nite use, that still needs 25 hours of sun. So you need much more than a 200 watt panel. Bottom line, you need to calculate your needs much more carefully. PS, 700 watts is very large. Check it. Are you using all that stuff at the same time?

Q: What maintenance is required for solar panels?: Solar panels require minimal maintenance. Regular cleaning of the panels to remove dirt, dust, and debris is recommended to ensure optimal efficiency. Additionally, inspecting the panels for any damage or signs of wear and tear is important. It is also advisable to monitor the performance of the solar system regularly. Overall, solar panels are known for their durability and reliability, requiring little ongoing maintenance.

Q: I want to buy a solar panel kit but I'm unsure of how it works. Basically I want to run my entainment set, Xbox, cable box, 46 led tv, and some desktop speakers. I went online and found a kit for like 250 or something like that at homedepot and was wondering if that kit is worth the money or go bigger or something.: It isn't really that simple. First you have to decide if you are going to use it after dark and in cloudy weather. If so you are going to need batteries to store power. You are also going to need an inverter to convert the direct current, low voltage power to 20 volt alternating current. Once you have made those decisions you need to determine power requirements. Look at the back of each piece of equipment and find the wattage rating for the device. Add them together and you will have a starting point for power consumption. Since you will want to charge the batteries during daytime and you have parasitic drain from the inverter use you want to increase that number by 50%. When selecting the number of panels you want you have to assume they will not operate at the optimum they do deteriorate over time so de-rate them by about 50%. Once again, look at the data plate to determine wattage and get enough panels to meet the power requirements using the criteria I have mentioned.

Q: What is the principle of solar panels to convert solar energy into electricity?: Solar cells are a pair of light response and can convert light energy into electrical devices. There are many kinds of materials to produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now the crystal as an example to describe the process of photovoltaic power generation.P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.

Q: Can solar panels be installed on a parking lot or carport?: Yes, solar panels can be installed on a parking lot or carport. In fact, this is a growing trend known as solar carports or solar parking lot canopies. These structures not only provide shade for vehicles but also generate clean and renewable energy. They are a great way to utilize unused space for solar power generation while providing additional benefits such as reducing heat island effect and offering covered parking.

Q: I been considering to get a solar panel system but I don't know if I'm going cut my electric bill every month , It's a lot of money to spend and I'm not really sure: We okorder /

Q: Can solar panels be used to power a film set?: Yes, solar panels can be used to power a film set. Solar panels convert sunlight into electricity, which can be used to power various equipment and lighting on a film set. This renewable energy source offers a sustainable and environmentally friendly alternative to traditional power sources.

Q: Do solar panels require permits for installation?: Yes, solar panels generally require permits for installation. The specific requirements and regulations for obtaining permits may vary depending on the location and local building codes. However, in most cases, permits are necessary to ensure compliance with safety standards, electrical codes, and zoning regulations. It is advisable to consult with local authorities or a professional solar installer to determine the exact permitting process in a specific area.

Q: How hard is it to install solar energy panels on your house? Is this a reasonable way to produce 00% of your house's energy? Is there any danger?: The panels are relatively easy to install. The batteries and the inverter tend to be heavy and you will need many people or mechanical assistance. You are talking about high current DC thus if you touch the wrong wires it's CC (Cancel Christmas - Rescue Squad Term). You also also dealing with lead acid batteries so they need to be well ventilated or we have another CC situation. Should you have a short, the batteries will overheat and explode projecting sulfuric acid... And the best part is when all is said and done, you are only paying twice to three times the cost for the electric over the life of the system as compared to buying the electric from the power company.

Q: How do solar panels affect the roof's integrity?: Solar panels generally do not affect the roof's integrity when installed properly. In fact, they can even extend the roof's lifespan by providing protection from elements like sunlight, rain, and snow. However, it is crucial to hire experienced professionals for installation to ensure proper mounting and sealing, avoiding any potential damage to the roof.
