Q:How to connect or use Solar Power Panels?
You need to know some electrical basics. You need to check if they are still working and determine the output voltage with the use of testers. They are just part of a system that includes other equipments as well like a controller, car batteries, inverters, diodes.
Q:how much power do i need from my solar panels?
Complex question.... Let me try to simplify it some: Make a list of every electrical device you MUST have. Add to the list how many hours a day it is actually ON. Add to the list how many watts (listed on the label or Volts times Amps) the device uses. (If you have a measuring device, use it.) For each item, multiply volts times hours = watt-hours (this is total energy used per day). Also, add the watts column for all the devices (this is the maximum instantaneous power to be used). Your solar panels should be able to provide power for your total load, so your panel's output power should equal the maximum instantaneous power used. If you can limit how many devices are used at a time, you may be able to reduce the panel size. Look at the total watt-hours. This is the total energy. Your panels generate maximum output when they are perpendicular to the sun at noon on a clear day. They generate reduced output in the morning and afternoon. They also generate substantially reduced output on cloudy days. Also, did you want electricity at night? On cloudy days? You will need batteries.. lots of batteries. And batteries are inefficient.. figure about 50% efficiency after a few years. Basically, here is a very rough formula: Panel_watts = Load_watthours / hours_sun_daily / 60%_angle_efficiency / 50%_battery_inverter_efficiency Once you've figured out the panel's watts, watts/volts=amps. Your system can be 2V with more amps, or 48V with /4 the amps... but the watts are the same. Just the wiring is different. For the battery bank, you need to determine how much backup power you will need for nights and cloudy days. Look at the watt-hours needed at nite, multiply it by the number of days and then by 2, to allow for battery aging. Unless you only have a couple devices and an LED light or 2, it is going to be VERY expensive.
Q:someone knows about solar panel?
A Mobile home will have its frame grounded when connected to a standard electrical 'plug-in', if it was built to current Codes. If you plan to use that panel as the entire electrical system you'll need to ground the frame. Vehicle systems, (frame grounded), are 2 Volt for a reason. It would be unwise to use a separately derived 20V. system in that mobile home if that frame's not grounded. (That first step out on to the ground could be a 'lulu'.)
Q:Question about solar panels?
The latter one has some strategies to consider for cutting your power consumption even more by timing your freezers and refrigerators..
Q:Solar Battery System?
Deep Cycle Series batteries are designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycles (deep cycles). They are typically used where the battery is discharged to great extent and then recharged.
Q:Do you know that China is the largest producer of solar panels in the world?
Solar voltaic panels are not 30,000 dollars each, a good panel, 24.4Vmp, times 95 watts, is about 900 dollars. Solar electric generation, makes sense, not because of the myth that the energy transmission companies 'buy' the energy you produce in excess (energy companies, zero out the balance at the end of the year, so that it only makes sense to design a system that equals your needs, not exceeds them). Solar electrical generation, is the future of energy freedom, but the powers that be, do not have yours' and my economic freedom in their portfolio. They are actively pursuing the globalization, to push down the working class, to the 'post industrial age', where the working classes, can once again, be relegated to serfdom, while the super rich, drink DOM, and watch us toil in the sun.
Q:What is the best low power alternative for TV set, to use as screen for dvd player, with a 30watt solar panel?
Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
Q:How much Silver do we need for Solar Panels?
Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.
Q:Chem question regarding using solar panels ....?
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
Q:Can I plug a solar panel into a wall socket to lower my electric bill?
You can use a solar panel to heat water, and you can generate electricity, but you can't plug it into a wall socket. The most effective way to save on your energy bill is by heating water. Solar panels that produce electricity, don't store it. They produce it for that particular time, and if you're not there to use it, it's gone. Furthermore, the electricity isn't always regular, it may have peaks and shortages. The best way to tap into that, would be to sell the electricity you produce to the grid, and then buy it back when you use it.
