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.

Q:Is it possible to store energy from solar panels for night?: This Site Might Help You. RE: Can you get energy at night from solar panels? Is it possible to store energy from solar panels for night?

Q:How do solar panels affect the electrical grid?: Solar panels can have both positive and negative effects on the electrical grid. On the positive side, solar panels generate clean and renewable energy, which reduces the reliance on fossil fuels and decreases greenhouse gas emissions. Additionally, solar panels can help decentralize the grid by allowing individual households or buildings to generate their own electricity, reducing strain on the overall grid. However, the intermittent nature of solar power can pose challenges for grid operators, as it requires careful management to balance supply and demand. Moreover, the increased number of solar installations can also lead to voltage fluctuations and grid instability if not properly managed. Overall, while solar panels offer numerous benefits, their integration into the electrical grid requires careful planning and coordination.

Q:all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?: The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.

Q:I'm thinking of having solar panels to generate electricity. The drawbacks are that I'm afraid if it needs repair, I won't be able to find anyone. Also I'm afraid that the roof is not very accessible. If it is a new house, should the roof have a roof hatch? What can make the system not work?: Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.

Q:If I wanted to add solar panels to my home to produce on average, 8 kWh of electricity daily, how much do you estimate it would cost using state of the art technology?I live in Virginia (Washington DC Metro Area), and I have Dominion Power. I pay the following electric rates:Jun-Sep $0.0904/kWhOct-May $0.0776/kWhAnnual Ave: $0.0824/kWhDistribution charges add on approximately another $0.0228/kWh.How long would the ROI for an 8 kWh/day solar system be?: Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .

Q:Can solar panels be used in areas with high levels of rainfall?: Yes, solar panels can be used in areas with high levels of rainfall. Rainfall does not necessarily affect the functioning of solar panels as they primarily rely on sunlight to generate electricity. However, it is important to ensure that the solar panels are properly installed and maintained to prevent any water damage or reduced efficiency caused by excessive rain.

Q:I want to install a solar panel system and our power grid can't work in reverse(so it get its electricity from us). My question is how do you prevent electricity from our panel to go to the grid without disconnecting the grid? How can we also use the grid and the panel at the same time when the panel are not creating enough power?PS dont say ask an electrician: If you are grid-tied, then a standard solar electric system will always feed back into the grid if you are not utilizing more power in your home than is being generated by the solar panels and inverter system. It is possible that a grid isolation device designed to prevent direct back feeding is available, but haven't heard of one in common use. New laws in most areas of the US are now mandating that utilities allow grid-tied alternative energy systems. Double-check you local laws. Sometimes you can't take the utilities word for truth--most will automatically say 'no' and will only relent when you show up with the law in hand. Unfortunately, some utilities have figured out another way to shut down alternative energy pioneers--they demand multimillion dollar insurance policies covering damage that their equipment could sustain from your little PV system. Technically, they are still in compliance with the law, they just make it impossible for a homeowner to meet their requirements. If you are getting the runaround, go to your state representative for help. It's amazing how contrite those utility people can be when a state senator (or even US Senator) has just sent a letter asking them why they are stonewalling a law-abiding and well-meaning citizen. Good luck, and don't give up!

Q:How to make a simple solar panel?: It's pretty basic, but I hope this helps!

Q:I really want a projector but i hear they use a lot of energy because of the lamp. I want a good one to watch movies and play games on. but i don't want one that is gonna kill the lighting bill.is there like a solar panel or something i could use for it. PLZ HELP.: Do understand, that a solar panel is slow to pay for itself. Let's say your electric bill was $200 a month ($2400 a year). A solar system would cost perhaps $24,000 so you would actually have paid your first 0 years of electricity in advance when installing the panels. After that 0 years, you start to be ahead financially. It can still be a good idea, but it may not be the quick and cheap solution you were looking for.

Q:Can solar panels be installed on a carport?: Yes, solar panels can be installed on a carport. In fact, carports are an ideal location for solar panel installation as they provide ample space, unobstructed sunlight, and can also serve as a shade provider for parked cars.
