Solar panel refers either to a photovoltaic (PV) module, a solar hot water panel, or to a set of solar photovoltaic modules electrically connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be used as a component of a larger photovoltaic system to generate and supply 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 320 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, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.
- Q:hi, i got a pond and i am planning of putting some lights on it during night time. but i want to use solar panels and i have done a bit of research about solar panels and i know how they work, i know that the common voltage to use is 2v so you can use car batteries or deep cycle batteries, but my question is:. what wattage of bulb can you recommend2. how long it would take to drain my battery (can i have it overnight)3. and what wattage of solar panel should i get enough to recharge my battery the next day.hope anyone can help..thanks
- You can get 6V cells and SLA batteries. You would get a panel and batteries suitable for the lights you get though. Depending on what you want to do, you shoud look into LED lighting, which is more efficient than incandescent. You do not want to drain your battery flat. Rather you want to draw only 2/3 of its capacity of so. You would find the lights you want (likely 2VDC), and add up the current they draw, and get a battery that would supply enough capacity (in AH, which is amps time hours) for a couple nights use (to account for weak solar days), and a solar panel to charge two days of use in one good day. You would use a charge controller so that the solar panel does not over charge the battery, and some sort of dusk timer to turn your lights on at dusk and off several hours later.
- Q:Can solar panels be used in areas with high levels of bird droppings?
- Yes, solar panels can be used in areas with high levels of bird droppings. However, regular cleaning and maintenance may be required to ensure optimal performance of the solar panels and prevent any potential damage or obstruction caused by the bird droppings.
- Q:I had an idea for new parabolic solar panels shaped like horseshoes. They can install them outside buildings facing the equator. They could angle them from the ground based on how many degrees latitude the location and rotate them according to seasonal changes. The disadvantage of photovoltaic panels is that they are not all capable of receiving direct sunlight. That is the quintessential reason I believe horseshoe solar panels are more effective than flat rectangular ones. One side could function in the morning; the middle could perform at midday; and the other could operate during the evening. That method seems more sensible than hourly positioning. I'm certain horseshoe panels could save and produce more electricity. A football stadium, shopping mall, or outlet center would be a fantastic place. What do you think?
- The panel's own shadow at different times will defeat the purpose. In addition large areas of expenssive panel will remain idle. Flat panels are the most economical solution.
- Q:If my school uses 88240kWh of electricity per month and I have 000 50W solar panels running for 6 hours a day, does it mean it will take 88240kWh / {{[(50W x 3600s)*000]/000}kWh x 6} number of hours to generate that much electricity (88240kWh)?
- running six hours a day doesn't mean much. You need to look at the solar insulation charts for your school's geographical location to come up with a better factor. The easiest number for you to use is sun hours. For example, Washington DC averages 4.23 hours. Do a Yahoo search for sun hours and you should find lots of charts. Solar panels rated at 50W give this output at full sun near noon at full brightness (no clouds). The sun hour factor makes it easy to find the equivalent number of full brightness hours. So, using Washington DC as an example you have: 000 panels * 50W * 4.23 sunhours/day = 634kWh a day on average. You state your school uses 88240kWh/month which is 6274kWh a day. This would mean you need ten times more solar panels since there is no way to get more daylight. Be careful to put in all the units in your formula and cancel them out to make sure you don't end up with a nonsense result. The title of the question would be answered as followed: 50W/000 * 4.23 sunhours/day = 0.63kWh/day or 9kWh per month or 228kWh a year. These are annual averages. If you wanted a specific month, you would need the sun hours for that month. Hope this helps.
- Q:Is it possible for the everyday person to increase the efficiency of solar panels that they own? If so, how is it done?
- There are 3 (simple) ways to increase the efficiency of a solar panel at home - they all work by increasing the amount of light that falls onto it: . Have the solar panel track the sun throughout the day so that it always faces it; 2. Place a lens (larger than the panel) in front of the panel that focuses the light from the sun onto it. 3. Have mirrors around the panel than redirect light from themselves onto the solar panel. (e.g. imagine a satellite dish with the solar panel at the front and the dish being all mirrored.)
- Q:when building a solar panel should the diode be on the positive or negative sidelittle more detail i just built a solar panel and im running it to a grid tie converter should i put diodes in if i add another panel or are they only for battery systems?
- the blocking diode goes on the positive side
- Q:What are the maintenance requirements for solar panels?
- The maintenance requirements for solar panels include occasional cleaning to remove dirt and debris, checking for any damage or loose connections, and ensuring that the panels are receiving sufficient sunlight. Additionally, regular monitoring of the system's performance and scheduling professional inspections can help identify and address any potential issues.
- Q:Can solar panels be damaged by hail or strong winds?
- Yes, solar panels can be damaged by hail or strong winds. Hailstones can cause cracks or fractures in the glass surface of the panels, affecting their efficiency. Additionally, strong winds can potentially dislodge or break the panels if they are not properly installed or secured.
- Q:Photosynthesis is fairly inefficient, but efficient enough to power all life on earth.
- Silicon is a very good conducter. Probably the best for electricity.
- Q:What specification of solar panel would I need to power a laptop every day? I would need to use it for about 0 hours or so every day. I don't know anything about solar panels, but I am seriously thinking of getting one now and don't know who to ask.
- Ive been employing the comparable photograph voltaic panels for 5 years, have flow some instances so as that they final lots longer than the roofs weve had over us. i'm coaching my young ones a thank you to construct wind turbines, because of the fact we shop having potential failiures whilst the wind blows. and recently its have been given very windy. I can charge banks of battery's and shop my place of work working from dc-ac converters.
