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'm thinking of these solar panels that people have on their rooftops in domestic properties. I suppose I mean after how long do you break even with respect to just carrying on without them and getting you electricity from the utilities companies? Or answer in any way you think is pertinent. The more info the better.
- Hi Warne, Payback period of solar panels depends on three main factors: ) Amount of solar radiation available: the more solar resource available at a site, the shorter the payback period will be. The insolation level is a function of latitude, cloudiness, elevation and some other factors. 2) Availability of grants, incentives and tax credits. Reducing the initial cash outlay is a great way to speed up profitability. For example, in the US, the 30% federal tax credit greatly reduces the payback period as it puts some of the cash back in your pocket in a short amount of time. Minimizing the initial cost has a big impact, since money in your pocket today is always worth more than money down the road. 3) Net metering or feed-in-tariff. If you are able to sell back your excess power, or all of the solar electricity to the grid, then you can also improve the payback period. Feed-in-tariffs are not very common in North America, but net metering is an option. Investing in energy efficiency measures (e.g., LED lights) at the same time as solar may help generate more excess power and help with the bottom line. There are some online calculators which may help you put all these together for a specific site. I'm including a link below.
- Q: I had an idea for new parabolic solar panels shaped like horseshoes. They can install them outside buildings facing the equator. They could angle them from the ground based on how many degrees latitude the location and rotate them according to seasonal changes. The disadvantage of photovoltaic panels is that they are not all capable of receiving direct sunlight. That is the quintessential reason I believe horseshoe solar panels are more effective than flat rectangular ones. One side could function in the morning; the middle could perform at midday; and the other could operate during the evening. That method seems more sensible than hourly positioning. I'm certain horseshoe panels could save and produce more electricity. A football stadium, shopping mall, or outlet center would be a fantastic place. What do you think?
- Sorry to be a prophet of doom again but the fault in the system is that only a small portion of the cell is used at any time of the day, given the high cost of solar panels this is not financially viable. Why not just have a small motor to turn the panel to face the sun, that's been done and it works.
- Q: Can solar panels be integrated into buildings?
- Yes, solar panels can be integrated into buildings. In fact, many buildings today incorporate solar panels into their design to generate clean and sustainable electricity. These integrated solar panels can be installed on rooftops, facades, or even as part of the building materials themselves. This integration helps to maximize energy efficiency, reduce carbon emissions, and lower energy costs for the building occupants.
- Q: Can solar panels be used for powering electric fences?
- Yes, solar panels can be used to power electric fences. By harnessing the sun's energy, solar panels can generate electricity that can be stored in batteries and used to power electric fence systems. This renewable energy source offers a sustainable and cost-effective solution for powering electric fences in remote areas or locations without access to traditional power sources.
- Q: Can solar panels be damaged by hail or other weather conditions?
- Yes, solar panels can be damaged by hail or other severe weather conditions such as strong winds, heavy rain, or snowstorms. Hail can cause cracks, dents, or shattered glass on the surface of the panels, reducing their efficiency or rendering them completely ineffective. Additionally, extreme weather events like hurricanes or tornadoes can also cause structural damage to the mounting system or dislodge the panels from their position. Therefore, it is important to consider the weather conditions in a particular location and choose appropriate measures to protect solar panels from potential damage.
- Q: Can solar panels be used to power a train?
- Yes, solar panels can be used to power a train. Solar panels can convert sunlight into electricity, which can then be used to power various electrical systems on a train, including propulsion. However, the feasibility and effectiveness of using solar panels to power a train depend on factors such as the size and efficiency of the solar panels, train energy requirements, and the availability of sunlight.
- Q: want to add solar panels to manufactured home, and we get a lot of snow up here in the NW. Wondering if it would interfer with the roof load.
- The okorder if you would like some ideas on how to do this.
- Q: Why should I have a Generator if I have Solar Panels.....?
- Usually, a generator is more cost effective than a battery backup system for your solar panels. Most grid-tied solar arrays are connected to the grid without batteries. My company has installed well over 00 solar arrays for residential and commercial clients and almost none of them had battery systems with them. Many clients asked to see the costs and after that, they agreed that a generator seems better, especially if there is access to fuel readily available. Also, unless there is a battery system, the solar inverters will not operate when the electricity goes out. This is a safety feature, but it keeps you from using any power at all from the panels when the grid goes down. This explains the utility interactive solar inverters compared to the stand alone generators.
- Q: How much per sq inch do they cost? Will i have to worry about them blowing off during hurricane season? If the sun isnt out for a week will my power go out? Will I have to check them every week and check which ones arent working and replace them? Is there anyway for them to be damaged by acid rain or any type of erosion like hail? When do I have to replace them? How do I dispose of old ones (like recycling)? What is smarter and more economical having few big panels or many small ones? I know I have alot of questions but I want a good detailed answer.
- The cost of solar is measured in dollars per watt. That means the cost of a cell that can make one watt continuously in full sunlight. A friend of mine is starting a new job to set up a new solar cell factory and he said the present cost is $3 per watt, but that they expect to get that down to $ per watt in a few years. They can be damaged by weather, just like any regular roof. My insurance agent asked if I had solar panels, so it is a factor in insurance cost. I never heard of recycling or disposing of old panels, maybe because they are so new and last so long that not many are ready to be disposed of yet.
- Q: There is a charge controller that has what i believe to be only port for a solar/ wind turbine control panel and i don't know if it has more than port for panels. So would i be abed to link 2 panels to port or do you think the controller has more than portBTW it is for marine use.
- Solar panels are like batteries, hook them up in series and you increased the voltage, hook them up in parallel and you increased the current. You should review your first year physics notes on the matter.
