PRODUCT DESCRIPTION:
Solar cells are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current;our solar cells have passed IEC Certification. With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.

- Q: i am trying to figure out how many solar panels can be placed on one acre of land and how much they cost to install
- The size you pick, therefore, should be decided on per your requirements. A 4kw system will need between 0 and 20 solar panels, with an initial cost of around ?7,000 for the module and installation. Systems larger than 25kW can't be accommodated on existing buildings. Instead this option is for those of you with vacant land, a location such as a farm or another open space.
- Q: I've been looking into solar panels. They are fairly expensive ($35k or so). My state has some rebates and grants available. Is anyone aware of any federal grants and rebates other than the federal tax credit? We are subject to AMT tax and can't take the credit. (Which is ridiculous, is the federal government committed to conservation or aren't they??????)
- I have some panels on my house and no they are not cheap. If you look around you can buy them for around $4.70 per watt for a 00 plus watt panel, this will make them $470 or more. But you will get a first quality panel. And no I do not know of any fed. government programs for home owners. These kind of programs usually only go to large companies. And it does not look like our government is going to help seeing how the let the large oil companies keep there tax programs but refused to help solar. This just happened today when the senate voted on the energy plane. Good luck go solar
- Q: My mom's house has some solar power panels on the top of her house but they are not connected to anything. They don't even have wires or anything like that. Does anyone know how to connect and make solar panels work? Thank You
- They may be connected and running, but you just can't see the cables because they are concealed. Of they may not even be electric. They may be solar water heaters that have water lines running inside a black box. Did your mom purchase the house with them on there? If so, can she contact the previous owner to learn who installed them and why? In the absence of any meaningful information, I would suggest that you call a solar company in your area and have them come out to tell you what it is that you have.
- Q: Can solar panels be damaged by birds or other animals?
- Yes, solar panels can be damaged by birds or other animals. Birds may create nests under solar panels, which can cause damage to the wiring or block sunlight. Additionally, animals like squirrels or rodents can chew on the wires, potentially causing electrical issues. It is recommended to take preventive measures, such as installing barriers, to protect solar panels from such damage.
- Q: How do solar panels affect the property's curb appeal?
- Solar panels can enhance a property's curb appeal by providing a modern and environmentally friendly image. The sleek and futuristic design of solar panels can add visual interest and a sense of innovation to the property, making it stand out in a positive way. Additionally, the perception of the property being energy-efficient and sustainable may increase its desirability among potential buyers or tenants.
- Q: I need a solar panel for my laptop as i am going camping in the desert, and i need my laptop. There are two choices of solar panels, One is 0 watts and 2 V and maximum power current 0.56 amps. The other one is 2 watts, 2 V and no mention of current. My laptop plug says input 00-240V and .5A and then output 5V-5A. Which one should i get for my laptop. If there are other choices please tell me ill look them up on OKorder.Thanks
- I'm afraid neither of these panels will do much for charging or running your laptop. If the power brick is supposed to emit 5 volts at 5 amps, that's 75 watts. Neither of those panels provides enough voltage and the power output is obviously far too small. The capabilities of solar power are vastly overestimated for small panels. Sunlight is limited to about kilowatt per square meter under ideal conditions (summer time, clear blue sky, for a few hours around noon in the US southwest). But consumer panels top out at about 5% efficiency, so your limit is 50 watts per square meter - in other words you would need about half a square meter, or about six square feet, of panel to provide 75 watts. And even under ideal conditions you will only get that much for a few hours each day. Also, the panel's voltage output is not regulated, so even if you find a panel that emits 5 volts (this would actually have to be made up of groups of 30 cells in series, as they emit half a volt each at most) you can't just connect the panel output into your laptop's DC in. You'd need a regulated DC-to-DC supply, and since that is not 00% efficient it will cost a bit of the power... now you need even more panel area. All in all, not really a practical thing to carry along on a camping trip.
- Q: Hoping to find instruction, materials list and hardware needed to construct solar panels myself, how many and make it happen instead of talking about it
- Silica based solar cells are not the kind of thing you whomp up in you basement. Here are a couple ideas for solar systems you can build and install yourself. Take a 4 x 8 sheet of /2 inch plywood. Frame sides with 2 x 4's. Screw tin cans in a staggered row (checker board) pattern inside frame. The more cans the more heat you get so place them nearly touching. Paint cans and entire assembly flat black. Cover top with glass, plexiglass (best) or heavy mill clear plastic (cheapest)Place on roof. Drill 3-4 inch holes in opposing sides. Run pipe or tubing into house. Attach to small low speed fan. The black paint will absorb sunlight and heat. The air moving through box will carry heat into house. It's a cheap efficient way to help heat your home. You can vary size and shape of box to fit your roof. If you use more than one box, hook them up in series. More boxes mean more surface area means more heat. To heat water. Take a steel tank. A car gas tank works well. It is galvanized so it won't rust, is cheap, and easily available at any auto salvage yard. But you will have to flush in throughly to remove gasoline odor. A steel 55 gallon drum is easier to work with but may cost more. Paint exterior of tank flat black. Weld/glue/clamp water pipes to tank. Place on ground in area that gets lots of sunlight. Attach water supply to tank and route discharge pipe to house or appliance. Black painted steel absorbs heat from sun light and heats water. In spring and fall you get warm to hot water. In summer you get scalding hot water and in winter you get cold to luke warm water. Both of these solar powered systems are seasonal and their output varies according to location and climate, but they are very inexpensive and easy to build and provide FREE heat and/or hot water for many years with little or no maintainence.
- Q: i want to charge my mytouch 3g with solar panel(s) it has a 500mah 3.7v 4.4wh batterieswhat do i need to charge it can i use RadioShack 0.5W Solar Panel 4.5V or RadioShack? W Solar Panel 4.5V
- see u have to make ur own ckt for this ur solar panel generate DC if u want to charge ur phine then its convenient way to harge with ur charger for this do this search for net to convert DC-AC convertor since ur charger work on AC so when ur solar panel generate DC it convert into AC that will charge ur phone in ckt u need this thing filter and amp ie the DC voltage come from solar panel 2 DC to AC convertor 3 AMP for AC 4 filter for AC and u are done....... fine ckt from google.....
- Q: Are solar panels affected by shade?
- Yes, solar panels are affected by shade. Shade can significantly reduce the efficiency and output of solar panels as shading obstructs sunlight, which is necessary for generating electricity. It is important to install solar panels in areas with minimal shade to maximize their performance and efficiency.
- Q: Can solar panels be installed on a hospital or medical facility?
- Yes, solar panels can be installed on a hospital or medical facility. Solar panels can help hospitals and medical facilities reduce their electricity costs and reliance on the grid, while also promoting clean and sustainable energy.
