Product description
It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

- Q:Dear Friends, I am very much worried about Global warming, So to contribute something for reducing Global Warming I have decided to use Solar Panels. Can anybody tell me what is the price of these Solar Panels and why people are not using them when they are environment friendly. What are the Pros and Cons of these Solar Panels?
- Solar okorder / And thin film solar panel power stations are about 50-60% cheaper now than solar power was in 2000. But they're still not economic in most places. Mike K's claim that solar panels produce more pollution than 'traditional' power is wrong. Coal is over 900g CO2/kWh, plus loads of pollution. Gas is ~400g CO2/kWh.
- Q:Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?
- 0 of the panels wired in parrell will give you enough power to trickle charge the batteries. You will need a charge controller to prevent a overcharge from damaging your batteries. A panel array that is rated at 2 volts actually puts out a unregulated voltage up to 2 volts. I have bought some charger controllers from OKorder at good prices. They will also prevent the discharge of your batteries at night or when the panels are in the shade. If the panels only put out 5 volts they will not charge the batteries. Check each panel outside in the sun with a DC volt meter for proper operation before connecting them.
- Q:Do solar panels work during a power outage?
- No, solar panels do not work during a power outage unless they are connected to a battery storage system.
- Q:If a solar panel has a power rate of 80 Watts and efficiency of lets say 30%. Does that mean the maximum power this solar panel can generate is (30/00)*80=54 Watts or its just 80 Watts?
- If it says STC or Standard Test Conditions on the nameplate or documentation, then that means 80 watts under bright sun at an unrealistically cool temperature. It is rare to see that power in real life, except when the perfect storm of conditions come together. There is also a PTC rating for some panels, which is more realistic. If the panel does not say STC or PTC, the manufacturer is free to make up whatever test they feel like, which generally leads to ridiculously overstated power. As for efficiency, for residential panels, that's generally only of academic interest. A 80-watt panel is 80 watts, regardless of the efficiency. A more efficient panel will take up slightly less space, but most people are more interested in the total price, since roof space is generally not an issue.
- Q:Can solar panels be installed on forests or protected areas?
- Solar panels can be installed on forests or protected areas, but it is important to carefully consider the potential environmental impact and sustainability of such installations. Proper planning and assessment should be conducted to determine the potential disturbance to ecosystems, wildlife habitats, and biodiversity. In some cases, it may be more appropriate to explore alternative locations or prioritize the use of existing infrastructure for solar panel installations.
- Q:if you know the area of the panel can u calculate for the wattage or voltage of the panel..
- One square meter of solar panels can produce up to 50 watts of maintenance-free power for up to thirty years. The most common solar panels are for 2 V applications. For sq meter: I = P/V = 50/2 = 2.5 A A single solar cell always produces a voltage of approximately 0.5 volts, regardless of its size. For higher voltages, you have to connect individual cells in series to add their voltages. The larger the solar cell, the greater the current will be. You can also connect cells in parallel to increase current. Hope this helps!
- Q:I've built a set of lights, fan and a clock running on only solar power. The problem is, i have to present it tomorrow and when the light isn't particularly strong it won't work too well. It works flawlessly when its under my desk light on max brightness but the only the light works when i set it to low brightness. Currently, tomorrow in my city it won't be sunny so any advice for trying to make it work under low light?
- Solar panels are designed to be used to recharge a battery or series of batteries, not for direct power. That is the inherent weakness of solar systems. The only way to have it work in low light conditions if to have several cells wired in series and have a voltage regulator to limit the amount of voltage that can be supplied. Other than that, add a battery and a charging circuit that the cell would supply power to.
- Q:What is the impact of roof orientation on solar panels' performance?
- The impact of roof orientation on solar panels' performance is significant. The orientation of the roof determines the amount of sunlight the panels receive throughout the day. Ideally, solar panels should be installed on a south-facing roof to maximize their exposure to sunlight. East and west-facing roofs can also work, but they may produce slightly less energy. North-facing roofs are generally not suitable for solar panel installation as they receive the least amount of sunlight. Overall, roof orientation plays a crucial role in determining the efficiency and effectiveness of solar panels.
- Q:Can solar panels be used in areas with limited space?
- Yes, solar panels can be used in areas with limited space. There are various types of solar panels available, including smaller and more compact designs that can be installed in tight spaces such as rooftops, balconies, or even on the sides of buildings. Additionally, solar panel technologies are continuously evolving, allowing for improved efficiency and the ability to generate more power from a smaller surface area.
- 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 and cost-effective solution. By installing solar panels, these venues can generate their own clean energy, reduce their carbon footprint, and save on energy costs in the long run.
