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: Are there any disadvantages to using solar panels?
- Yes, there are a few disadvantages to using solar panels. Firstly, the initial cost of installing solar panels can be quite high, although this cost has been decreasing in recent years. Additionally, the efficiency of solar panels can be affected by factors such as weather conditions and shading. Furthermore, solar panels require a significant amount of space for installation, which may not be feasible for everyone, especially in urban areas. Finally, solar panels are dependent on sunlight availability, making them less effective during cloudy or nighttime conditions.
- Q: I have a playstation PSP charger that is 5v 2A, so it takes 0 watts.I have several small solar panels that put out watt a piece and are 4 volts, 250mAhow can I get my 0 watts to be 5v 2A instead of 4v 250mA? the voltages have to match up right?also, what's a 3-T regulator that controls voltage?
- The first item is whether the psp charger output is ac or dc. IF, AC then you are stuck as the panels put out DC. (Increasing the voltage enough to cover invertor losses is not practical in this instance!) IF DC, then you need to combine panels to produce 2 Amps, after which it is run through the 3 terminal VOLTAGE regulator to limit the voltage to 5v. That is 8 panels in parallel in 2 groups placed in series = 2amps at 8 volts, then add regulator for 2 amps at 5v. (Parallel increases amps, series increases volts.) Total panels required is 6 panels.
- Q: Can solar panels be used in combination with wind turbines?
- Yes, solar panels can be used in combination with wind turbines. This combination of renewable energy sources allows for a more reliable and consistent power generation, as wind and sunlight are complementary in nature. By integrating solar panels and wind turbines, the system can generate electricity during both day and night, as well as in varying weather conditions, maximizing energy output and increasing overall efficiency.
- Q: What materials are solar panels made of?
- Solar panels are typically made of photovoltaic (PV) cells, which are primarily composed of silicon, along with other materials such as metal frames, glass, and encapsulation materials.
- Q: Hi I need to replace the solar panel on my calculator and was wondering where I could buy one. Thanks in advance for your answers.
- My suggestion is to first make sure that your calculator does not also use a tiny button cell. It could just be that the battery went dead. Also know that it's probably less trouble to just get a whole new calculator. If you have the skills to replace the solar cell, I'd suggest first disconnecting it, and wiring a .5 volt battery in its place. If that doesn't work either, maybe the problem is not the solar cell at all, but just its connection, or even a dirty ON button. As for where to get a replacement solar cell, if it were me, I'd go to a dollar store, and see if they have a cheap solar calculator that I could harvest one from.
- Q: I have a home made 24 volt electric cart. It is powered by two 2Volt deep cycle batteries. Since the motor runs on 24 volts the batteries are wired in series to produce the 24 volts. I only have a 2 volt battery charger, but I also have two 2 volt solar panels. It is a pain having to unhook wires, rewire it, or charge them one at the time.HERE IS THE QUESTION REALLY... Can I wire the two 2 volt solar panels together in series (ie: negative to positive) then connect it to the existing 24 volt system and have it charge the batteries fine. I know basic wiring, but I know nearly nothing about solar panels, will it work fine? will it cause them to break? or short out?(additional info, the solar panels are only rated at 5 amps so it will not overcharge the batteries or anything)
- Wiring the panels in series should be ok as long as they are exactly the same. Different impedance's could damage the panels. Remember that Voltages and Amperage's are indirectly proportional meaning that if you series your panels your voltage will rise but the amperage will be reduced.
- Q: Can solar panels be installed on a building with historical significance?
- Yes, solar panels can be installed on a building with historical significance. Many historical buildings have successfully incorporated solar panels into their design without compromising their architectural integrity. This allows for the preservation of historical structures while also promoting sustainable energy practices.
- Q: so...do you think an online store dedicated to selling solar panels/systems will be a good business idea? Since green energy is the 'hottest' growing business area recently with usage growing about 30% per annum and investors putting all their money into solar energy, wind farms, biofuel, etc. I think when you sell solar systems online this will be the most appealing business model to the end customer...especially if you offer free installation on orders of say $000.
- Did okorder , you will see thin film going for 99 cents a watt at times. The crystalline kind of panel that goes for $2.35 a watt is more like $.50 wholesale, and that's for a major distributor, not a (forgive me) small order of $60k, which is less than one container. There is a coming glut of panels, and prices will fall, but that means both wholesale and retail prices. I'm not saying it won't work, but do good research. For example, I think there are many more than 3 or 4 online shops for solar panels. Investigate shipping an warehousing costs. Investigate whether Home Depot really does not offer installation (every time I go in there, I see a guy handing out flyers for installation). And research carefully how much it will cost to provide installation. The typical install requires skilled and licensed workers. It won't be legal in most places unless someone has the necessary certifications. It's not just a matter of screwing the things to the roof. Any roof penetration has to potential to leak if done improperly. And any electrical wiring has the potential for burning the house down. Whatever business you finally pursue, research carefully, or that $60k will flee from you like a jackrabbit.
- Q: OK so how do these solar panels supplement the AC from the grid? Like do they invert the output of the solar panels and sync two AC sources together? If so how and with what? Or do they convert the AC from the grid to DC and then supplement and then invert it? If so how and with what? Thanks
- The okorder /
- 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.
