Product description
A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon
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.
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: Hi. I need to build a solar panel for a project. it should be able to light a 60 watt light bulb. also, it should be about 3x3 ft if it is 50% efficient. if anyone knows any websites or can help me, please answer! thanks.
- Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
- Q: I thinking of buying a few solar panels, can anyone who had bought solar panels or sells them give me a price for them. I dot wanna over spend on them...
- Hello, Solar panels range from 200 to 400, depends on where you get them from. I got a good setup from iron edison which came delivered. I bought a 00 watt solar panel for $225, upon opening the delivered package, it was a high quality, clean cut panel that really obliged me to power it with a high quality battery. So I searched all over the place for HIGH quality solar batteries/asked many people, and came across VMAX solar batteries. These are top of the line, they have the best lifespan out of all the batteries I've tried and have been buying them from Bargainshore for years now. I recently bought more panels and used the the same setup, couldn't be happier! Goodluck!
- Q: My house uses 500 kw a month, air conditioning is the main consumer, is it possible to install solar panels in my roof to produce this amount, and aproximate cost, thanks .
- 500 Kw
- Q: Can solar panels be integrated into building materials?
- Yes, solar panels can be integrated into building materials. This integration is commonly known as building-integrated photovoltaics (BIPV), where solar panels are designed to function as part of the building's structure. This allows for seamless incorporation of solar energy generation into the building's overall design, enhancing energy efficiency and aesthetics.
- Q: Does anyone know how I would go about hooking up the air conditioners in my house to solar panels? I would want just the air conditioners to be powered by solar energy. How could I hook it up where the panels can absorb energy from the sun during the day, and save and store the energy so I can run the air conditioners at night? I really feel that in the long run, this would save a lot of money with the energy bill. It's the use of the air conditioners that drive up the bill. Is this idea feasible? Is it also possible to have some sort of hybrid system where I can switch from solar to my regular local energy source when I want to?
- There's no need to connect only the A/C to solar, nor is there a need to use batteries. Both of those problems are solved with grid-tied solar. The solar electricity system works alongside your regular, and the A/C just plugs in normally. You never need to worry about switching. During the day, if the A/C is drawing power, the solar goes into that, reducing your draw from the electric company. If the solar generates more than the A/C needs, the meter is driven backwards. At night, the meter runs forward again. For example, the meter may read 5000 in the morning. By evening, maybe it reads 4975. At night, it creeps back up to 5005. When the meter reader comes, you would be billed for only 5 kWh. That's the general idea. Also, consider whether you can insulate your home more, and whether you might want to change out your air conditioners for new, DC inverter mini-split units. Those can use a fraction of the electricity per BTU of regular air conditioners.
- Q: Are solar panels worth the investment?
- Yes, solar panels are worth the investment. They have numerous long-term benefits such as significant energy savings, reduction in electricity bills, and a positive environmental impact by reducing carbon emissions. Additionally, many governments offer incentives and tax credits for installing solar panels, further enhancing the return on investment.
- Q: What are the maintenance requirements for solar panels?
- The maintenance requirements for solar panels typically include regular cleaning to remove dirt and debris, checking for any damage or wear, ensuring proper electrical connections, and monitoring the performance of the panels. Additionally, it may be necessary to trim nearby trees or vegetation that could block sunlight and reduce the efficiency of the panels. Overall, proper maintenance helps to maximize the lifespan and efficiency of solar panels.
- Q: What is the impact of shading on solar panels' performance?
- Shading on solar panels significantly reduces their performance as it obstructs the sunlight required for generating electricity. Even a small amount of shading on a single panel can lead to a significant drop in power output for the entire solar system. Hence, it is crucial to ensure that solar panels are installed in areas with minimal shading to maximize their efficiency and effectiveness.
- Q: We have LED at the output of 40 watts and is used for 0 hours giving us 400 Watts-hr of energy consumed.Rechargable batteries needed are 2 V. 400/2 gives us 34 Ampere-hour battery needed. If we want it for 3 days, It would be 34x3=00 Ah. So the battery needed 00 AhNow how do I select the solar panel which can charge this/these batteries? What should be its rating?
- First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
- Q: What is the impact of bird droppings on solar panels?
- Bird droppings can have a negative impact on solar panels as they can reduce the efficiency of the panels by blocking sunlight. The droppings can create shadows and reduce the amount of sunlight that reaches the panels, leading to decreased energy production. Additionally, the acidic nature of bird droppings can damage the surface of the panels if not cleaned regularly, potentially reducing their lifespan. Therefore, it is important to regularly clean and maintain solar panels to ensure optimal performance and longevity.
