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.[2] It is 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.


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 installed on a parking lot or carport?
Yes, solar panels can be installed on a parking lot or carport. In fact, this is a growing trend known as solar carports or solar parking lot canopies. These structures not only provide shade for vehicles but also generate clean and renewable energy. They are a great way to utilize unused space for solar power generation while providing additional benefits such as reducing heat island effect and offering covered parking.
Q:Alright my family and i are buying a new home in Bradford,Ontario, we we thinking about solar panels and had a couple questions:. how much are they each?2. how many will we need to power a single family home(4 ppl)3. where can we find them in ontario?4.how much money do they really save you?5.what kind of energy do they providfe you withand other basic info or a website i can check out would be great!thanks in advance!
I have a system that was installed last year. I have 20 panels which provide me with about 75% of my electricity. I do use less electricity than the average home. I use an average of 45 kwh in the summer, my neighbor uses more than double that. I paid $26K for the system, but I got a $0K rebate from my utility and the US gives a fed. tax credit. I am saving about $2K per year, so it will take just over 6 years to break even. I also have what I think is called net metering, my utility allows my meter to run backwards when I generate more energy than I use, so pretty much the entire time the sun is out in the summer. Having energy efficient appliances, reducing standby energy and using conservative climate control really helps keep my usage down. Weather striping, insulation and clean well maintained systems all help as well.
Q:Can solar panels be installed on farmlands or agricultural fields?
Yes, solar panels can be installed on farmlands or agricultural fields. In fact, many farmers are increasingly adopting solar energy as a way to generate additional income and reduce their reliance on traditional energy sources. By installing solar panels on farmlands, farmers can generate renewable energy while continuing to use the land for agricultural purposes. Additionally, solar panels can provide shade for crops, reducing water evaporation and enhancing plant growth.
Q:If i took a lazier pointer and aimed it a solar panel would it take in the light. Also what types of lights would work on a solar panel like L.E.D, uv light bulbs.

Q:i have this usb solar panel charger i am building and the solar panel is about 2by .5quot;, so i was wondering if a led light can power it, if so will one be good or would i need more? if so how many?
Yes, shining light from a visible-light LED on a solar panel will cause the solar panel to generate electricity. There is a long-wavelength cutoff (probably in the near infrared) where photons from an infrared LED would not have sufficient energy per photon to excite the solar panel, no matter how bright the LED was. Of course the amount of electricity produced is a fraction of the power needed to power the LED. The best possible efficiency you could achieve under optimal conditions is about 30%. The typical optical power output of a single LED is around 0.3 Watt. The density of sunlight is such that the amount of sunlight falling on a 2 x .5 area perpendicular to the Sun's rays is about .3 Watts. So maybe you'd want a few LEDs, or a particularly bright LED to simulate sunlight. But you'll get something with one LED. A bright LED flashlight would work.
Q:Hello Yahoo, I am doing another one of my wacky inventions however I need something that will give me 2V of power!I don't want to connect loads of AA batteries into a battery holder as this shall run out quickly and become expensive in the long run, I don't want to carry around a big car battery either.I have been searching around on OKorder .uk and found some Solar-Powered 2V Trickle Chargers. These say they shall work on cloudy days (which is perfect as the majority of the time that is all we get!) but could I use it as an independent power source?If I attached the thing I want to run to the solar panel will it supply it with 2V of power?
If you want to run something from a solar panel, you should remember that the power from the panel is only available when there is reasonable sunshine on the panel. Usually the solar panels are used with solar regulators in order to charge batteries. These batteries are used as energy storage for when the sun is not shining. Now, this does not mean that you cannot drive instruments directly from the solar panel and regulator. To do this, you will need a panel that has sufficient power to drive your instrument. An example is the solar powered garden or fountain pumps. I have driven 2V computer fans directly from the small solar panels - useful for cooling of things such as pool pump housings. The solar regulator is used to convert the solar panel output to a 3.5V output in order to charge lead acid batteries. I have used MPPT regulators (maximum power point tracking) which is more efficient than the standard solar regulator. If you don't use these regulators you may find the solar panel producing up to 7-9V in good sunshine which is not good for your instruments that are expecting 2-3V. Hence the answer to your question is that you will need to have a battery being charged to get useful power from the solar panels via a solar regulator.
Q:How do solar panels affect the property's branding and marketing?
Solar panels can positively impact a property's branding and marketing by showcasing its commitment to sustainability and environmental responsibility. It can position the property as a forward-thinking and eco-friendly option, appealing to environmentally conscious consumers and potentially attracting a larger customer base. Additionally, solar panels can contribute to cost savings and energy efficiency, which can be highlighted as unique selling points, enhancing the property's marketability and competitiveness.
Q:Can solar panels be installed on water treatment plants or utilities?
Yes, solar panels can be installed on water treatment plants or utilities. In fact, many water treatment plants and utilities are increasingly adopting solar energy systems to reduce their reliance on traditional energy sources and lower their carbon footprint. Solar panels can be installed on the roofs of these facilities or on nearby open spaces to generate clean and renewable electricity to power their operations.
Q:How much energy can be generated from a solar panel on a clear, bright summer's day for example?
it depends on the size of the panel and if it is installed in an optimal location. there are many 00W panels commercially available and they can be ganged for a number of different output configurations.
Q:In some countries where electric generation is low, they are not available easily.
Believe it or not, solar panels are so expensive in this country because of government subsides. Without market competition, companies have no obligation to compete with each other on price. If our government would stop paying people to buy solar panels and giving solar panel companies tax breaks, companies would be forced to lower their price and raise their quality in order to get you to buy their product. This would be true of oil/gas, corn, soy beans and a number of other companies and products as well.
