Benefits of Solar Power:
Following to RMI, Balance-of-System (BoS) elements, this is, non-module cost of non-microinverter solar modules (as wiring, converters, racking systems and various components) make up about half of the total costs of installations.
For merchant solar power stations, where the electricity is being sold into the electricity transmission network, the cost of solar energy will need to match the wholesale electricity price. This point is sometimes called 'wholesale grid parity' or 'busbar parity'
Specifications of Mono Solar Panel
Average pricing information divides in three pricing categories: those buying small quantities (modules of all sizes in the kilowatt range annually), mid-range buyers (typically up to 10 MWp annually), and large quantity buyers (self-explanatory—and with access to the lowest prices). Over the long term there is clearly a systematic reduction in the price of cells and modules. For example in 2012 it was estimated that the quantity cost per watt was about US$0.60, which was 250 times lower than the cost in 1970 of US$150.
Real world prices depend a great deal on local weather conditions. In a cloudy country such as the United Kingdom, price per installed kW is higher than in sunnier countries like Spain.

A: Actually we are only manufacturer of solar panels, but we could try to source them for you in China if you need. We could provide you an optimal system design to instruct you how to install.
Q: What is your warranty system?
A: For c-Si panel: 25years output warranty for no less than 80% of performance, 10 years output warranty for no less than 90% of performance. Free from material and workmanship defects within 5 years.
For a-Si panel: 20 years output warranty for no less than 80% of performance, 10 years output warranty for no less than 90% of performance. Free from material and workmanship defects within 2 years.
- Q:I have a home in Manchester Tn and we have been slowly remodeling the home. It is about 200 sq ft of living space. Our normal electric bill is about 50 a month. We would like to add some solar panels to the home to help reduce the amount of the bill. How many panels do I need and what would be the cost? I am not trying to go completely of the grid but I would like to start somewhere and maybe over the years be able to add. What is your recommendation for a reasonable cost of under 2 to 3 k??
- image voltaic panels can set you back as much as $20,000. A windmill that produces sufficient electrical energy for the abode would be approximately $0,000. Neither gets you off the electrical powered grid. image voltaic in basic terms works while the sunlight shines. At night, you will have not have been given any electrical energy. Wind in basic terms works while the wind blows on the merely right velocity. decrease than 5 mph and you get no capability. If the wind blows too speedy on your windmill, it is going to close right down to maintain from being broken. look to insulation, capability valuable doors and abode windows, an capability valuable air conditioner, landscaping that aspects shade.
- Q:Why would someone use a solar panel? Does it have to do with the economy right now, global warming, or what?
- It turns energy from the Sun directly into usable electricity and is very useful if you are far away from the power grid or want an alternative electricity source. Since energy prices must steadily rise and Solar cells are getting cheaper, it is likely that in several years Solar panels will provide electricity as cheaply as the big power companies who maintain our power grid.
- Q:I want to also know if the 0 watt rating on the solar panel is 0 watts per day or is it constantly adding 0 watts? Is there a time which the 0 watts is being added like 0 watts per second or 0 watts per minute and so on?
- You need more panel because it will take more than ones worth of sunshine to charge this battery so the battery will need to sit over night and wait to continue the charge. clouds will make the problem even worse. I use 24 - 00 Ah batteries with a 3500 watt system and I am using a 48 volt system. So my Ah = 24 X 00 / 4 = 600 Ah but this is at 48 volt so the watt hours are the same. But My computer puts the power where it is needed automatically. You have 25 watts for at best 0 hours per day = 250 Watt hours per day. That battery needs at least 200 x 2 = 2400 watt hours that does not take efficiency of any of the systems into account. As you can see this battery may never charge completely.
- Q:Got a small project here in a remote location. There is to be a 2 volt deep cycle battery, the equipment to be powered from battery and solar panel to charge battery. The 2 volt battery puts out 55 AH. the max constant power draw from the equipment to be powered is 7.9 watts. Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight?And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge?Thanks to all the input!
- Will a 30 watt panel at 2 volts be enough to run this system during sunlight and charge the battery for the equipment to run overnight? Maybe theoretically, but you're going to have very little margin for losses and clouds. I'll bet it has very little power when cloudy. 7.9/30 = 0.26. So at 00% efficiency, you'd need it to be charging more than 25% of each 24 hour period. In a summer with long days and a climate with few clouds, you might make it. But I think you're very close to the edge. And, at 55 AH, how long can I keep a constant draw of 7.9 watts without a recharge? For an ideal battery: time = Q V / P time = 55 A h * 2V / 7.9W time = 83 hours So you've got pretty good margin on your battery.
- Q:we are doing a fundraiser to have students pledge to make donations for a solar panel instalation on one of the school buildings. I am looking for a slogan for the campain.
- Solar Energy Is School! It's School To Go Solar!
- Q:Basically I need a custom solar panel created. I won't go into detail but the dimensions need to be around 4''x2.5'' and be as thin as possible.

- Q:how much do solar panels cost?
- The okorder
- Q:How much Electricity does a standard Solar panel producein terms of Watts and in terms of Units( i.e. electricity meter attached in our House)If I have 20 Solar panels and an inverter , how much electricity will I Be able to harness and store (state that in terms of volts)Can I run Arefridgerator, Iron, Heaters, Plasma T.V. and other high Electricity Consuming Devices.
- Take a look on OKorder at some of the books on how to design solar energy systems. It is a bit more complicated than you might expect. I'm not sure what you consider to be a standard solar panel, but the 3' ones I have produce about 5 watts of power in full sunlight. Put simply, you need to convert the power from the solar cells (variable voltage) into a constant voltage usable for charging a batteries. Most of the low cost modules for this purpose can't handle more than about 00 watts. Larger systems are available that handle thousands of watts but they are quite pricey. Since you can't take out more than you put into your battery system, you can calculate about how long you can run a high-current appliance based upon its wattage rating, that of the battery system (adjusted for loss of converting to AC), and the charging system.
- Q:Has anyone had roof problems caused by rooftop solar panels?
- Rooftop solar panels might cause all sorts of maintenance or poor installation problems but I rather doubt at this point if we can say that there is an issue with solar panels in general that will cause a problem with the roof. Rather solar panels tend to shade a roof on its most exposed side. Without solar panels southern facing roofs will wear out faster than northern facing roofs. Installed solar panels will tend to make the roof last longer.
- Q:im doin a science experiment and i have a battery that is 3.6 volts , does it matter wut voltage the solar panel that im connecting it to is . Does it need to match , be less or does voltage have no effect . If so wut does matter when choosing the type of solar panel to power a bettery?
- You really need a little more infomation about your battery. It should have a recommended range of charging current. You should not exceed that range. Your solar cells must be a higher voltage than the battery, but you should not connect the cells directly to the battery. First, you need a diode in the line to keep the battery from draining into the solar cells when there is no light. Second, you need a resistor to limit the charging current. You have a 3.6v battery. Let's say the charging current is 0.A. Use a 5v solar cell and silicon diode. The diode will drop the cell voltage to 4.3v. The voltage across the resistor will be .7v for .A current, you need a 7-ohm resistor.
