Company Profile
China National Building Material (CNBM) Group Corporation
CNBM Solar photovoltaic (PV) Panel is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array. Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.

- Q:i would like to hook up a power outlet to a solar panelmy light system is 500watts will run for 8 hours/day between noon to 8PM.So what is the most effective system do I need?
- Most efficient manner would probably be to use solatubes, or sun tunnels during lighting hours, then replace the 500 watt lighting system (assuming it's incandescent) with LED's, that should give you about the same light output for around 00 watts or a little less even. Then you need a solar panel that can produce 00 watts for as long as you want (at a 00 watt lighting system) or 200 watts for /2 the time you want, etc, etc. Allow a good 0% or so for inverter inefficiencies, and 0% or so for reserve, so 20 watt's per 00 watts. After you have this, you will want a charging controller, a battery, or battery bank (These should at very least be deep-cycle, or better yet golf-cart batteries with series between 2, and parallel between banks of 2 for the 2-volt portion of the system), with enough amp-hours to support your system, plus a good 0% or so reserve, plus another 0% or so for inverter inefficiencies (remember the over sized solar panel above, this is why), than of course you also need a 2-volt DC to 20-volt AC, 60 Hz system (or 240 volt AC 50 Hz system, depending on your AC system) inverter.
- Q:I want to build solar panels for my house.Dose anyone try okorder is this really work?
- you okorder they have solar panels
- Q:Can solar panels be damaged by birds or other animals?
- Yes, solar panels can be damaged by birds or other animals. Birds may build nests or perch on the panels, causing blockage of sunlight and reducing their efficiency. Additionally, animals like squirrels or raccoons may chew on the wires or cables, leading to electrical damage. To prevent such issues, various measures like installing bird deterrents or using protective mesh can be taken.
- Q:how the energy of load connected to solar PV measure.?Want too the basic idea about it.The role of current flowing thrugh the load?Can u explain with example..can explain simply?Im not an electrical student so explain very basics
- A solar panel is made up of solar cells. Each cell produces about 0.5 to 0.6 volts. Cells are connected in series, like the batteries in a flashlight. Enough cells are placed in series to produce the desired voltage. Cells produce very little current, so many strings of cells are connected in parallel to produce sufficient current. The output is direct current (DC), like that from a battery. A home solar system needs alternating current (AC), so an inverter is used to change from DC to AC. Some systems have batteries for backup power. In these some of the DC output is used to keep the batteries charged. Systems are measured in kilowatts. System sizes are chosen to meet the demands for electricity. My system has a 6 kilowatt (kW) rating. The true output is more like 4. Now that you know this much you can Google SOLAR SYSTEMS to learn more.
- Q:I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
- You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
- Q:Can solar panels be used to power a gas station?
- Yes, solar panels can be used to power a gas station. Solar energy can be harnessed through the panels and converted into electricity, which can then be used to power various operations and equipment at a gas station. This can help reduce reliance on traditional energy sources and lower the carbon footprint of the gas station.
- Q:Can solar panels be installed on a recreational vehicle (RV)?
- Yes, solar panels can be installed on a recreational vehicle (RV). This is a popular option for RV owners who want to generate their own electricity and reduce their reliance on traditional power sources while on the road. Solar panels can be mounted on the roof of an RV and connected to the onboard battery system to provide power for various appliances and devices.
- Q:Can solar panels be installed on museums or cultural centers?
- Yes, solar panels can be installed on museums or cultural centers. In fact, many museums and cultural centers are adopting solar energy systems to reduce their carbon footprint and save on electricity costs. Solar panels can be installed on rooftops, parking lots, or even as shade structures, providing clean and renewable energy for the facility's operations.
- Q:Are there any fire hazards associated with solar panels?
- Yes, there are potential fire hazards associated with solar panels. Although solar panels themselves do not typically catch fire, electrical malfunctions or faults in the wiring, inverters, or connectors can lead to overheating and fire. Additionally, if a fire breaks out in the surrounding area, solar panels can hinder firefighting efforts by creating potential electrical hazards and obstructing access to the roof. Therefore, proper installation, regular maintenance, and compliance with fire safety regulations are crucial in mitigating these risks and ensuring the safe operation of solar panel systems.
- Q:Can I add more solar panel let say up to 200 watt and adding two 2 volts battery using the same charges controller and power inverter?
- If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). Not exactly. Assuming the black panel establishes an equilibrium temperature, it's going to be losing exactly as much heat as it's receiving during the day. Some will radiate out into space, some will conduct or convect into the atmosphere. As a wild guess, maybe 50/50. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The panels are only about 4% efficient, so it's the same situation as the pure black panel for 86% of the energy. The remaining 4% will get stored in the batteries and then converted to heat at night. That heat will eventually leak out of the house and warm up the Earth a tiny bit. I think it's much the same situation either way. With the black panel the energy gets radiated / conducted/convected right away. With the solar panel a small percentage is stored and not so much is radiated, mostly conducted and convected. You're partly right as a black panel is going to radiate more into space than a house. But you're taking about maybe some day about 4% of % of the differening radiation/convection/conduction fraction, of the Earth's surface area. Probably not significant.
