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: How many kilowatts? Would it be enough to power my electric heat?Does one panel cost about $2000.?: The first thing to understand is that there is nothing complex about a solar panel. It is nothing more than a collection of solar or PV cells on a board that is fitted to the most appropriate part of your home, generally on the roof. There are guides out there that teach you how to build a solar panel and a windmill for just $50, and it’s very easy to make. Best of all, you can save 70% or more on your energy bill, adding up to thousands of dollars each year in savings. I reviewed both free guides and paid guides and have come up with our top to Build your own solar panels.

Q: I was looking at thin flexible solar panels as solar panels 500w a option to upgrade a 20w solar panel I have permanently mounted to the roof of a home made camper van.Why I was thinking flexible is at just 2mm thin they can be glued down and being flexible they will follow the contour of the rounded shape of the roof of my camper (boxy standard solar panel spoils the lines a little)Another reason is no glass to brake when traveling on dirt tracks(though I am surprised mine hasn't broken yet after thousands of km on corrugated dirt roads). Finally there is a weight saving at only /3 the weight or less then a standard glass panel.There are different grades of flex PV some of the more expensive ones are very flexible with extremely thin backing at around .5mm The ones I was looking at are cheaper and at around 2mm with a thin flexible aluminum backing.$250 is about the going rate for 20w OKorder job. Below is a pic of a smaller one 60w or so.Has anyone had any experience with them?: but it's very interesting and I wanted to ask you. In your case this is good solution, but I saw flexible panels in OKorder much cheaper than 250$. This is the price of standard solar panel 20w. Maybe your panels with better efficiency? I know that flexible panels are less than half efficient than regular panels, thats why you need twise more area to get the same output. What is your usage of this energy in this van? I know there are many ideas of solar cars, but if this solution is efficent enough today? Thanks!

Q: Can solar panels be installed in areas prone to hurricanes or tornadoes?: Yes, solar panels can be installed in areas prone to hurricanes or tornadoes. However, it is important to design and install the solar panel system with the specific weather conditions in mind. This includes using appropriate mounting systems, ensuring proper anchoring and reinforcement of the panels, and using high-quality materials that can withstand strong winds. Additionally, regular maintenance and inspections should be conducted to ensure the panels remain in optimal condition.

Q: Looking to install solar panels in my house.: Wholesale prices for BP solar panels range between $335 for the 40 watts panel to $835 for the 70 watts panel. Here's a brief listing of wholesale prices for BP solar models: - BP340J solar panel (40 watts) @ $335 - BP350J solar panel (50 watts) @ $37 - BP375J solar panel (80 watts) @ $504 Right now I'm getting a series of 50 watt (7.5 volts) panels installed in my house. It's a start to reduce dependence on electricity bills and try get some tax rebates as well.

Q: i took some solar yard lights apart and put them together in a series. i was told if you take AMPS times VOLTS = WATTS. do you test it with ac volt or dc volts? I tested mine with dc volts and got 4 volts in good sun and had my meter set on Ma or milliamps and got .83 which i am asuming that is .83 of one amp now i took those and multiplied .83 times 4 volts to = 34.03 watts. Is this large enough to charge a car battery in a day? And doese it make a difference for amps on how fast it charges or watts. i also was looking around and found 30 watt panels but had higher amps. I am very interested in building solar panels but i realize i dont know what i need to do to make shur they are big enough. my panel is only 9inch by 0 inch. It seems weird that i am putting out 4 volts: If a car battery contains 50 amp hours of charge at 2 volts, that's 600 watt hours of energy. divided by 34.03 watts, 7.63 hours to charge completely in direct sunlight. You don't want to connect them all in series. You want about 4 or 5 volts to charge a 2 v battery, so you should connect groups in parallel, and connect those groups in series to make your voltage. You'll end up with the same amount of power, lower volts and higher amps. It will work for trickle charging your battery if it's not too far run down.

Q: Does San Francisco get enough sunshine to really make solar panels a viable option for creating a self-supporting home? Certainly a wind turbine would be a good source of energy, but what about solar panels? Does S.F. get enough sunshine to justify using solar panels? It's overcast a lot in the Bay Area, are there any solar panels better than others for a climate like this?: I know nothing about the Bay area, I live in KC. However, I believe that solar is the best answer to alternative energy. We should have solar panels everywhere, the suns going to be shining somewhere. I propose we make gigantic panels in the deserts where the sun shines and nobody lives, and hook everybody up to the grid. They can store energy when they get a lot of sun to make up for the dark days. They are expensive to make so we should start building them one by one all over. The sun is not going to stop shining for millions of years. Plus there is no pollution from solar. So, yes put them in the bay and back here in KC too.

Q: why don't we take a cue from mother nature and make our soar panels like trees? thousands of leaves or needle (like a pine tree) instead of one big flat panel? I mean it seems to work pretty good for all the plants i see why would it not work for us. It would be aesthetically pleasing and with the right engineering wouldn't it make them not have to worry about tracking the sun? i already have some ideas about the process of making them just no available labratory.: Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.

Q: Can solar panels be used in areas with high levels of dust?: Yes, solar panels can still be used in areas with high levels of dust. While excessive dust can reduce the efficiency of solar panels by blocking sunlight, regular cleaning and maintenance can help mitigate this issue. Additionally, advancements in technology, such as self-cleaning panels or coatings that repel dust, are being developed to further enhance the performance of solar panels in dusty environments.

Q: Can solar panels be used in areas prone to hurricanes?: Yes, solar panels can be used in areas prone to hurricanes. However, it is important to ensure that the panels are properly installed and designed to withstand high wind speeds. Reinforcements, such as additional framing or anchoring systems, can be used to make the panels more resilient to hurricane conditions. Additionally, regular maintenance and inspections are necessary to ensure their stability and functionality.
