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.

FAQ
Q: Do you have the CE, TUV, UL Certification?
A: We’ve already passed all the tests, and any certificate is available.
Q: Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other
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 am doing a report about solar power and I need to know what determines the amount of electricity produced?example: exposure to sun, angle of panel, qualityplease tell me as much as you canmuch appreciated
- It depends on what you mean by amount of electricity. Normally that would mean the total energy produced over a given period. In that case, the main factors are ) Efficiency of the solar cells 2) Total irradiation received: incident radiation density times the solar panel area, and the angle of the incident radiation. Item ) is determined by the materials and method of construction of the solar cells Item 2) depends on the location of the panel, both on earth's surface (latitude), time of year, and how the panel is oriented with respect to the horizontal. Altitude of the location can also be a factor. Prevailing weather conditions, number of cloudy days, etc. are important. Independent of these parameters, larger area means more electricity.
- Q: If you need 9400 watts, 75 amps@ 240V, how many solar PV panels do you need?
- 75 amps @ 240 volts equals 8 kW not 9.4 kW, so first you have to make up your mind how much you want. Then you have to decide what size of solar panel you want. If it helps, the 6 units on our roof, each approximately m square, are rated for 4 kW in bright sunshine.
- Q: Also, where can solar panels be purchased in the Binghamton/Liberty/Jeffersonville area? Home Depot has some on their website I would like to see them in a store before purchasing or ordering them.
- Enacted okorder Hope that you find the above enclosed information useful. 09/9/20
- Q: the solar panel works with LEDs, small bulbs,etc but neve with any dcmotor. Please help. I have a science exhibition.
- Because its not voltage related its current related. look at the start up values for the motor w respect to current. This will be listed in amps or milliamps. Then cross reference that to the output of your solar panel also listed in amps or milli amps... ;)
- Q: I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
- There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
- Q: i want to know how to hook up solar panels to my existing power. all i can find on the internet is to use batteries and a inverter. but i want to use all of my existing lights and outlets off of the solar energy. i have heard that you can actually turn the meter backwards and use supplied power when needed. thats what i want to do and is it possible to do myself and if so, how?
- Contact your power company. They will advise you of the proper configuration. If you try to attempt this without notifying the power company and something goes wrong, they can and most likely will hold you responsible for all damages.
- Q: I thought that I had a fairly good understanding of watt's law, but i'm starting to doubt myself.If I have a load of 4500watts at 240 volts, how many watts of solar panels do I need, if the solar panels are at 2v?Yes, Yes... I have a charge controller, batteries, etc...So the way I looked at this at first:watts = volts * amps For the load4500 = 240 * xx would be 8.75aFor the power source (each solar panel)00 = 2 * xx would be 8.3a8.75 / 8.3 = 2.25, rounded up = 3So... based on that I came to the conclusion that I needed 3 solar panels...But... then I was thinking. Does it work that way?Or do I need 4500 / 00 = 45, aka 45 solar panels?In other words...If I have a 2v power source, how many watts do I need to drive a load of 4500w at 240v?ThanksMatt
- The easy way is to just use the power values. You need 4500W. Each solar panel delivers 00W (from a value in your working). Therefore you need 4500/00 = 45 solar panels. This is a crude calculation, ignoring efficiencies, voltage conversion losses and losses due to internal resistance. You would probably need quite a few more than 45 panels. ___________________________ I'll explain how to do the calculation your way. Each solar panel delivers 00W with a voltage of 2V. So the current is 00/2 = 8.333A. Each solar panel delivers 8.333A at 2V. But you require 8.75A at 240V panel delivers 00W. To get 4500W, you need: 8.75/8.333 = 2.25 times more panels to increase the current AND 240/2 = 20 times more panels to increase the voltage. So overall you need 2.25 x 20 = 45 panels. Of course if the power output of each solar panel is not 00W, you have to change the above calculation accordingly.
- Q: how much power is generated with solar panels? also please give me links for that information.and how much would the costs be for this alternative energy source?
- KW solar panels generate 5kwh power each day or so.
- Q: Can solar panels be used to power a school?
- Yes, solar panels can be used to power a school. By installing solar panels on the school's roof or surrounding areas, sunlight can be converted into electricity, providing a clean and renewable energy source. This can help reduce the school's reliance on fossil fuels, lower energy costs, and contribute to a more sustainable and environmentally friendly learning environment.
- Q: Can solar panels be installed on streetlights?
- Yes, solar panels can be installed on streetlights. This allows the streetlights to generate their own electricity from sunlight, reducing reliance on the electrical grid and promoting sustainability.
