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.
he photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. 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.

- Q: Is it really possible for me living in Denver to build and install and setup my own solar panel to help make electricity for my home?
- DIY okorder
- Q: Is it really necessary to make solar panels that expensive?
- First Solar recently announced that their costs to produce panels dropped below $ per watt. I don't know how much of that is accounting tricks. Of course, that doesn't mean that they would sell panels for that price - any capitalistic company is expected to drive the price up to what the market will bear. Crystalline silicon panel producers are coming in at about $2.50/watt right now for the best of them. But again, the selling price is what the market will bear.
- Q: Which kit did you use?How easy was it to build? How much did it cost to build the panels?How many kw or watts does it produce?Any other info on the kit or panels you built would be helpful.Thanks!
- sure, but if you don't know what you are doing you could really hurt or kill yourself. Basically you can do whatever you want on your side of the power meter and in the rare occurrence when your solar panels are producing more power that your home is using the meter will run backwards and you will be feeding power to the grid and theoretically reducing your power bill. At the very least you will be using less power from the grid
- Q: I need help?!!
- benefit- It makes use of the Suns organic engery to produce potential for a house/employer which saves money as against employing potential from the community materials for electricity. it will keep away from lots of money in case you reside in an area that is sunny a super style of the year. disadvantage- You extra suitable wish that is sunny for a on an identical time as to construct a inventory pile of potential. It somewhat relies upon on your desires for potential, in case you do no longer use incredibly some it and stay in a sunny section a super style of the year, then you incredibly could desire to have a super style of potential that only kinda sits there. yet once you reside in an area it somewhat is frequently cloudy all year around then image voltaic panels does no longer be superb for you.
- Q: Do solar panels require a specific type of wiring or electrical setup?
- Yes, solar panels require a specific type of wiring and electrical setup. They need to be connected in series or parallel to form an array, and the wiring should be designed to handle the direct current (DC) generated by the panels. Additionally, an inverter is typically used to convert the DC electricity into alternating current (AC) for use in the electrical system of a building or to be fed back into the grid. It is important to follow electrical code requirements and consult with professionals when installing solar panels to ensure a safe and efficient setup.
- Q: How do solar panels affect the property taxes?
- Solar panels can potentially affect property taxes as they may increase the value of a property. However, the impact on property taxes varies depending on the location and local regulations. In some areas, installing solar panels may qualify homeowners for tax incentives or exemptions, while in others, it may lead to a slight increase in property tax assessments. It is advisable to consult with local authorities or a tax professional to understand the specific implications in a particular area.
- Q: I am starting to think about solar panels as an option for my home. I have done some research on panels, to be honest its all very confusing. There are many different panels some with 60 watts some all the way up to 20 watts. My household currently uses about 2700 to 3400 kWh every two months. So based off of my power usage maybe you can answer some of the following questions:What kind of panels should I be looking at?Which panel manufacturers give the best bang for the buck (reliable/affordable)?Anything else I should be concerned about?I am just starting out in educating myself on solar power so please excuse me if I sound very naive. Any information that you may have will be helpful. Thanks in advance.
- Unfortunately, I can't give you a lot of specifics on what you should use. However, I can tell you that the very best system for you simply might not be available to you, in which case it really doesn't matter how good it is. Your best bet would be to talk to a supplier in your area and see what is available, THEN start looking at the differences between those. Unfortunately, solar panels aren't quite to the point of being a common-place product...yet. Another thing to consider would be how old your roof is. You might want to look into the possibility of building-integrated materials if you are in need of a new roof. Talking with somebody who sells the panels in your area will help you understand a lot more than just doing raw research. Get their take on it, then fact check and research what they tell you so you know you're not getting ripped off.
- Q: I would love to put in solar panels on my roof, but how hard would it be, and how expensive? Would I be able to do the work myself, or would I have to hire a pro?Also I live in Oregon, so much of the time it is overcast, so would it really be worth it?
- Not a good idea. The reason why panels are that much more expensive than cells is that the panels themselves are not that cheap either. If you start with the cells, you'll need - mechanical protection (hail, ice, snow) - electrical protection (i.e. waterproofing - if water comes in contact with the cells and wires, you'll get electrolysis which will corrode your wires and contacts faster than you can say 'b*mmer') - that setup will need to withstand temperatures between -20 and +30 °C (only guessing, might be worse) - oh, and the side facing the sun must be transparent (as far as possible) Now as to connecting the stuff: no, it will be neither easy to connect it to the house power nor to the grid - which is why that step (at least) in all countries I know of must be done by a certified electrician. If you get it wrong and you're lucky, only _your_ inverter will explode. Regarding the power: these 4W per cell (or kW for your shed) is the peak value, i.e. with the sun shining orthogonally onto the cells on a clear day. Since this (for a fixed installation) will only be true (at most) for a few minutes on a few days each year, your overall yield will be significantly less, probably more like 4 kWh/day for each clear day for each kWpeak you install _IF_ the shed roof is oriented exactly south and inclined towards the sun's noon position at the spring/autumn equinox (i.e. inclination angle = your geographical latitude). How many clear days do you have in britain? Yes, I had a similar idea for myself - but for one thing, the registered companies I addressed apparently weren't really interested in that small fry, plus the cost of the system + setup would barely have been amortized after the expected lifetime, even taking into account the (german) governmental subsidies. If I had the money to spare, I'd rather invest in a communal solar park. Much better ROI, the large installations get much better prices (per kW) for the setup.
- Q: Still researching for a car that fully uses solar power energy, suggestions would be nice to.
- certain.The body length to cabin area ratio very small in the picture voltaic automobile.subsequently there are 2 determination to make it ideal for useful use. It must have very large wing area to domicile the picture voltaic cells or a separate connected again vechile might want to carry the picture voltaic panel. yet I have some diverse theory in effective use of image voltaic ability.i exploit it for my workplace fan rapidly from image voltaic panel with out any charging and recharging mechanism.It provides very sturdy air in the course of my workplace hours. the most extreme priced battery is prevented in my layout. it truly is operating nicely in my workplace from the previous 6 months. Our authorities non convectional ability park has shown interest in installation one of their park.
- Q: a fiber optic network could distribute solar energy from warm states to the rest of the country. Using a Federally created program,the energy would be used through a trust program to benefit all of our citizens equally. It would create thousands of jobs and help us with our dependence on foriegn oil supplies. This is no different than work programs created by the Feds during the 930's depression era.
- This is a great idea, but there are some intrinsic difficulties with the theory: First, the average US household uses 27.4kWh of power per day= aprox. 0,000 kWh per year. Solar panels create kWh/m^2/day. Therefore you would need 27 m^2 (290 ft^2) of solar panels per household. Not only does that use a lot of space, but it would also cost a fortune. We also have to take into account that the government does not want us to become dependent of oil for many reasons. Therefore it is unlikely the government would ever consider paying for it. Lastly, for power grids to stay functional at all times, backup power plants must be kept 'hot', to replace solar power stations as they stop producing. There is an energy cost to keep plants 'hot', which includes (in the case of coal plants) the burning of coal. Unfortunately, if the country is not willing to accept brownouts, the carbon footprint of any large scale solar project will have to accept the 'hot' non-producing power plants carbon emissions as their own. The continued advances in the ability to store electricity will greatly impact the successful implementation of a large scale solar power station being, carbon footprint free. However, it would be possible for every household to have their own solar panels. Since they would need about 290 ft^2 (or 5ft x 5ft), then it does seem reasonable that they could have this much on their roof or land somewhere. Any additional energy you make from the solar panels you can sell back to the power plants and make money. They could then use this extra energy to cover in brown out situations, etc. In order for this to work though, we would all need to be responsible for purchasing and installing our own solar panels. It would be nice if the government would offer greater incentives to do so.
