- Q: I'm about to buy one but I don't really know which one is best for my home.
- One will give you enough DC voltage to light a 25 watt light bulb, [ one 45 watt panel is around $400. ] Now if your wanting AC voltage You have to buy a inverter, 5 or 6 deep cycle batteries, a switch Cables to transfer the voltage, a place out side to store the batteries, instalation brackets for the roof A Permit to Install them
- Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.
- Yes, you can purchase a solar photovoltaic array to keep your batteries charged. You will need a Photovoltaic Cell Panel that produces 27 + watts (6volts x 4.5 amps = 27 watts) at 6 volts of electricity, a Charge Controller that allows only 4.5 amps of power through to the battery and will reduce the amps as the battery nears full charge and shut off the Panel when the battery is fully charged, and a 6v. Battery. Figure you will need a photovoltaic panel capable of producing a minimum of 27 watts if you are going to charge a completely dead 6 v. battery in one day. (with a clear sky). The way the system works is the sunlight strikes the cells on the panel and releases the excess electrons in the cells, they travel along central wires to your battery and charge the battery. When the sun sets, the procedure is reversed and the electrons flow backwards from the battery, into the photovoltaic cells. That is where the Charge Controller is needed. It acts a one way gate and lets the electrons go into the battery, but won't let them go backwards to the Panel. Just set your panel in the sun at the optimum angle for the season and your latitude on earth, connect the charge controller and then the battery, and it will keep your battery charged. Don't waste your money on the small wattage solar photovoltaic systems that claim to keep your battery charged. They simply can't do it unless your battery is in like new condition and is fully charged when they are hooked up. If you battery is a few months old, the small wattage photovoltaic systems can't keep up with the loss of power from sulfation inside the battery.
- Q: Can you please tell me how much a solar panel costs?Please back up your info with a website.
- If okorder /.. Low-cost crystalline panel manufacturers such as Suntech are believed to have costs in the $.50/watt range today - making it $300 for a 200-watt panel. That doesn't mean that one can buy a panel for that price, of course. If you mean a DIY panel from purchased solar cells, the cost would be closer to $360 for an equivalent-powered panel, not counting the price of the frame, and the labor. A homebuilt panel would not stand up to decades of weather unless one spent even more on the frame. And since such a panel would not have safety certification, it could not legally be connected to the grid in most places. If you meant a water heating panel, please update or post another question - I'm sure people will chime in.
- Q: We are looking in to buy solar panels for our house. The payment has to be around or under $4000. Our house is a 4 bedroom and 3 bath 2-story house. (Around 2500 sq. ft.) Where can we get the solar panels? Also: Will it heat our water? When we get the solar panels, what direction do they have to be facing?
- U can get solar panels on OKorder stores rather online or else where on yahoo store online and u have to put the solar panel on every spot on the roof.
- Q: I am thinking of buying a 3w solar panel called the nomad 3 from goal zero. I want to charge 35Wh lithum batteries. I have heard that lithium batteries are temperatmental and without a regulated current things could get ugly.I have a couple of chargers that came with the batteries. One is a 2v car charger and another is 0-240v wall charger.Goal zero sell something called a sherpa 50, which contains rechargeable batteries and an inverster and I think they suggest that I charge my batteries indirectly through the Sherpa 50, however, the sherpa 50 is expensive at $200, and seems to have a small capacity, in addition to being extra weight that i don`t want to carry.Electronics geniuses, you are my only hope.
- If you want to energy each USB ports on the identical times, It could not be possibble. Your sun panel best provides 2.24 Watts (20V * 0.2A) of energy and you ought to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses out of your regulator(s), you are going to be method over your vigor finances. You'll want extra of a sun panel or less of a load.
- Q: Can solar panels be installed on research facilities or laboratories?
- Yes, solar panels can be installed on research facilities or laboratories. In fact, many research facilities and laboratories are increasingly adopting solar energy as a clean and sustainable power source. The installation of solar panels helps reduce carbon emissions, lowers electricity costs, and promotes a greener and more environmentally-friendly approach to conducting scientific research.
- Q: Tell me complete installation I have one 50Ah battery two 80 watts solar panels about 30 meter DC wire i charge ontroller and 000watt inverter. How i hook two solar panels to charge controller to battery then inverter?
- Wires from panels go to controller input terminals. Controller DC battery terminals to battery so that the controller will protect batteries and split power as required by demand to the inverter. Output DC on controller to inverter. Output AC or outlets on the inverter to AC appliances. One thousand watts is not very much capacity. It will keep your computer running and a lamp to read by. It won't run major appliances. A hair dryer is typically 500 watts and could not be run by this system.
- Q: What is a good sight that I could go to about installing solar panels and all of the considerations of it?
- Just okorder
- Q: Ok so my electric bill is through the roof because of the air conditioner (mini-split). Is there any kinds solar panel I can buy at a store and install it myself? Do I need any skills? Which brand? blah...blah...blah...
- Unless you live in an area with a very high UV index, like Las Vegas for example, solar panels are not cost-effective. You definatly should not attempt to install solar power yourself if you intend to power a residence with it (unless you live in a shack). A certified electrician is required in order to connect your equipment to your house's electrical system. It isnt just as simple as a few panels. You need a converter that turns the DC voltage generated into AC. You also need equipment to connect to the metering system for your house. If you want to see if it is cost effective, you will need your electric bills that show usage for a year and the price per kWH. There are a lot of websites that have calculators for solar power systems.
- Q: How do you know when it is a good deal to buy a solar panel. For example, what is a good cost per watt, how many volts should I expect, etc.
- first okorder / example: house roof is 20' x 20' 20' = 240, so sq. inches of roof is = 57,600 say rain fall for your area is 3 per month on average. 57,600 x 3 = 72,800 of rain collected. Using the conversion chart link above, that many cubic inches of water = 750 gallons of water free per month. Look at your water bill and see how much you use. Solar panels take on average 2-20 yrs to pay themselves off, just in time for them to be replaced. Paddle wheels go on for just about forever. We still find large paddle wheel mills in the USA that are over 200 yrs old, and still functioning.
