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:Can solar panels be used in areas with high pollution levels?
Yes, solar panels can be used in areas with high pollution levels. While pollution may slightly reduce the efficiency of solar panels by blocking some sunlight, they can still generate electricity. In fact, using solar panels in such areas can be beneficial as they provide a clean and renewable energy source, helping to reduce reliance on polluting fossil fuels.
Q:So I reckon it's time to install some of these bad boys. it's come to point where electricity providers are charging such extortionate amounts that I can definitely see these reaping huge rewards before long. (Okay I might be exaggerating a little - they are pretty costly themselves).The problem is I've read around that they're only fitted to south facing houses? Why so? Why can't they be installed on the rear side of the roof - the side facing the garden? My house is facing north, so the front door leads north. Could I have solar panels installed on the back? (That's basically my question, with a bit of a rant too lol).Cheers.
You want the panels facing south because that is where they would get the most sunlight throughout the day. If your front door is facing north, then the back of your house would be facing south, right? So put them up in the back where they are facing south...haha wtf..
Q:How do solar panels affect home insurance rates?
Installing solar panels on a home typically has a positive impact on home insurance rates. While the upfront cost of installing solar panels can increase the replacement value of your home, resulting in a slight increase in premiums, many insurance companies offer discounts or special policies for homes with solar panels due to the reduced reliance on traditional energy sources and the increased energy efficiency. Overall, solar panels can help lower home insurance rates in the long run.
Q:i am working on a project which requires small solar panels. i am looking for ones about 3X4. is there any way i could get these? and where?
I bought mine from OKorder. They were from a top seller and arrived in better condition than I expected. They are 3 X 6 and have an output of .5 volts .7 watts. You will need other items as well blocking diodes, charge controllers as well as tabbing ribbon and buss wire. Learn about other components you may need at the website below. There is also an OKorder link at the bottom of the page.
Q:So my buddy and I have an idea to start a small Solar Installation business. Small as in I am only willing to do one weekend a month and two weeks a year(I know it sounds like the reserves). These are my specific question:) What is the average cost in the U.S. to have Solar Panels installed?2) What is the average cost in the state of Hawaii to install Solar Panels?3)Is this a worth while venture? (There's a good chance i'm going to ignore this one anyways LOL!)4)How long does it take to install a photovoltaic solar panel?5)How long does it take to install a hot water solar panel?6)Besides the obvious, what permits are needed to get our start?7)What education or Cert. is needed?8)Average time to start up?If there is any other information you believe pertinent to this subject that I didn't ask directly, please share. Thank you for your help in advance!
The North American Board of Certified Energy Practitioners (NABCEP) is the “gold standard” for PV and solar heating installation certification. Cost vary on the size and difficulty of the project. The price of the panels are dropping and technology is getting better. A rough rule of thumb estimate would be $3 per watt for all the hardware and then double that to cover labor and overhead (insurance, permits, gas for the truck etc) Solar thermal has a faster payback than PV. The panels themselves go up fairly quickly. Installing roof mount attachments can take some time. This is also one of the points of liability. If done improperly the roof may leak and cause more damage than the profits on that job could pay for. There are a number of kits and pre-bundled packages available. You might try installing one of those on a friendly first. Make it a weekend project for yourself or on a friend or relatives house.

Q:How do solar panels affect the local economy?
Solar panels can have a positive impact on the local economy by creating jobs in the installation, manufacturing, and maintenance sectors. Additionally, the use of solar energy can reduce electricity costs for residents and businesses, freeing up funds that can be spent elsewhere in the local economy. The deployment of solar panels can also attract investments and contribute to the growth of a sustainable and eco-friendly image for the community, potentially boosting tourism and attracting new businesses.
Q:Are there any free classes to learn about solar energy and building a solar panel

Q:im trying to run my house with with solar panels, is it possible? if so please let me know how....i have a 6000 w inverter
There are a variety of factors that come into play in order for you to calculate the answer. Additionally, there are a number of variables that can make the answer change over time. The number of solar panels you need to install to power your home will depend upon your electric power demands, the weather in your area, the angle of your roof, shade issues from nearby trees or buildings and the size of the cells. All of these factors are important and must be built into your calculations so that you can create the best solution for your home and your future needs.
Q:i've heard environmentalists like ed begley jr use the phrase quot;peak shaving hourswhen talking about solar energy.what does that phrase mean, please?thank you to all who respond.
From a power company's perspective, it costs more to supply electricity during hours when electricity use is high. The times of day when power use is the highest are called peak hours. Historically power companies would sometimes charge large power users a higher rate during peak hours to encourage them to shift their electricity use to other times of the days. With the development of smart power meters and smart grid technology, it's now possible to offer the same incentive to individual home owners. so i'm wanting to eventually get solar panels.? If you live in an area where the electric rate varies depending on the time of day, then peak shaving improves your payback/return of investment on grid tied solar panels. Particularly in areas with high air conditioner usage, the peak hours generally correspond to the times when solar panels generate the maximum power. Look at it like this: Suppose your power company charges you $0.5/kWH during off peak hours and $0.30/kWH during peak hours. Because the solar panels generate the most power when the cost of electricity is the highest, it is easier to justify the cost of installing the panels because you are avoiding buying electricity at the highest rate. If your power company just bills you at a flat rate at all times, then it becomes more difficult to justify the cost of installing the panels and associated equipment..
