Product description

 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.

 In 1883 Charles Fritts built the first solid state photovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient.

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.

loss and possible damage because of the reverse bias applied to the shadowed cells by their illuminated partners. Strings of series cells are usually handled independently and not connected in parallel, though as of 2014)individual power boxes are often supplied for each module, and are connected in parallel. Although modules can be interconnected to create an array with the desired peak DC voltage and loading current capacity, using independent MPPTs (maximum power point trackers) is preferable. Otherwise, shunt diodes can reduce shadowing power loss in arrays with series/parallel connected cells.[citation needed]

Q:DIY single solar panels with outlets?
I wanna start going green you know like solar panels.
Q:What is a disadvantage of a solar panel?
They are costly, although technology is improving. To generate enough current to be useful, the panel needs to be large quite large. The sun tracks at different angles depending on the season and the solar panel would need to be repositioned to get maximum current generation because of this.
Q:Should the value of solar panels be included when appraising a home?
Normally solar panels are listed as part of the house that supply heat, like a water heater or furnish. Your house would be appraised the same without the solar panel. Since the house you are references sold 4 months ago this might not be a comp your appraiser would have used. Normally a house would have to be sold within the past 90 days to be used by an appraiser. You are able to challenge the appraisal of the house you paid for. The appraiser would take a second look at the cops he/she used in coming up with the valuation of the property and see if here was something that was over looked. If you want to challenge the appraisal based on the fact that you have solar panels, it is doubtful there would be any changes. By adding the solar panels to your house might have been over built your house for the neighborhood. Look around your neighborhood to see how many other houses have solar panels. Normally in an area where houses are valued at around $200K or so would not normally be equipped with solar panels. This would not add value to your house as other houses in your neighborhood would still appraise for the same, since they would not have solar panels as the house you indicated in your statement did not have. I hope this has been of some benefit to you, good luck. FIGHT ON
Q:What does solar panel output refer to?
Solar panels are rated under standard test conditions (STC), a certain amount of light at a certain distance, at a certain temperature, etc. A kW, or kilo watt, is 000 watts. So for the amount of time that the sun meets those conditions, the rate of output is 500 watts. An average location has an average of 5 sun hours a day, the total time that you produce the rated output. Watts is a rate, like miles per hour (mph), how fast it is going. Watt hours, or kilo watt hours (kwh) is a quantity, like miles. So if you drive 50 mph for 5 hours, you went 250 miles (50 mph x 5 hours). If you produce .5kw for 5 hours, you have the potential to produce 7.5kwh a day. Multiply that by 30 days in a month, you get 225kwh a month. In reality you will lose about 30% of the rated power from less than ideal weather, system losses, etc., so it's more like 50kwh a month. You can look at your electric bill to see how many kwh you use a month, maybe around 000kwh, and see what percentage of your usage a system like that can power.
Q:Solar Panel Question?
It depends very much on where you live. If you live in Nevada, Arizona or California solar panels might be a good idea. If you live in Canada don´t expect to get your bill to zero... 800 kwh/month means an average consumption rate of about 2500 watts. 6 panels would cover that. But your energy consumption isn´t cosntant and nor is your energy production from the solarpanels. If you go off to work during the day when your panels produce the most then you probably produce excess electricity. Check with your utility if it is possible for you to sell off that electricity by putting it on the grid. Then you buy back electricity when you´re watching tv and surf the web at night. You loose money and electricity like this (or by using batteries as suggested above) so I would underdimension my solarpanel capacity. It makes sense if it is cheaper to just buy electricity at night. The retailer and the manufacturer should have charts showing how much their 65 watt panels really produce at different times of the day and the year for your location. Oh, and I´m sure there are ways in which you could reduce your electricity consumption. Smart lights, energy efficient lights are easy ways.
Q:45 Watt Solar Panel -?
Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish
Q:Are solar Panels worth it?
Solar panel systems are one of today's best investments! What other product can you get that last for 25 years or more and saves you money every day of the year, but pays itself off in 5 to 0 years in most cases. Our company has installed well over 00 solar panels systems for clients who have declared independence from their utility! Contact us to learn more if you are in the Northeast US.
Q:Single Solar Panel savings?
I am afraid you are in for some disapointment. A typical solar panel might put out something over 00 watts, and cost a pretty big bundle. Then, what would you do with the power? It will be low voltage DC. You could charge a battery, or run a DC appliance. You would get less than ten cents worth of electricity per day. If you wanted to use it for household appliances, you would need an inverter. More big bucks. Type solar panels in the green search box at the top of this page, and read previous Q A. Also do the same on the Internet. Sorry to be a wet blanket.
Q:Information on making solar panels?
I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.  I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).  In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.  A link to a Pricewatch-like website for current prices on solar panels is below.  Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:  I am reporting all of Agua-Luna's cut-and-paste pieces as spam.  I encourage others to do likewise.
Q:I'm have a DIY solar panel and wanted to use micro inverters?
I okorder.com/.. 2) A Gel Cel or automotive battery to hold the solar power. Once you have those parts connected, you can run an extension cord to your security lights to power them at night with the solar power you have collected during the day. Later, you can expand your solar array and power numerous appliances like a refrigerator in your garage or even a freezer. I have been using solar power for several months now and deeply enjoy the ability to create renewable energy. I wish you luck with your efforts as well!
