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: What is the average payback period for solar panels?
- The average payback period for solar panels is typically around 7 to 10 years. However, this can vary depending on factors such as location, system size, local energy rates, and available incentives.
- Q: I am looking for an average sized solar panel (Just Panel), not 2 big n not 2 small. Any idea where i can find in abudhabigt;??
- I know where in Dubai , just go to Naif road where they sell the satellite equipment , there are a couple of shops that sell all kind of solar panels and dish equipment stuff. Sorry can't remember the name, But it is right in front of the paid parking lot (the private not public one).
- Q: I remember hearing somewhere that solar panels may attract light rays away from plants thus having a potentially negative effect on the plants. I can't remember where I heard it but I'm curious if there is any truth to it.
- not so. the sun shines on the earth and everything on it. the solar panels are on the earth like on top of your house maybe.if they were not sitting on top of your house , the sun would still be shining on your roof. it makes no sense to say they were drawing light away from other plainest when the sun would still shine on the place where they are if they were not there.
- Q: I was wondering if they create other forms of energy besides electrical that is unwanted. Like heat due to the friction of something, or sound. Also why is a solar panel not able to collect 00% of the energy that is striking its panels. And how could the efficiency of this be hypothetically improved.
- Science. The best solar panels we have only get like 22% of the sunlight for conversion into energy. That is simply the best they know how to make with current technology. And for that your talking about a mobile panel that tracks the sun as it moves at the equator. A solar panel in say Canada is lucky to get 0% even on a sunny day. But even if a solar panel got 00% efficiency, it's still not a lot. Sunlight is too diffuse to be a good power source, and you'd need to cover lots of ground to get power. Worse, you can only get power when the sun is out during the day. So for power at night you'd need a battery, or another source of power. The 'newest' idea is to capture sunlight to make 'lasers' that boil water, to turn turbines and make electricity. They cost way more then they are worth right now though...
- Q: What happens to solar panels during a power outage?
- During a power outage, solar panels will stop generating electricity unless they are connected to a battery backup or an alternative power source.
- Q: Can solar panels be used in cold climates?
- Yes, solar panels can be used in cold climates. While the efficiency of solar panels may slightly decrease in colder temperatures, they can still generate electricity even in freezing conditions. In fact, solar panels can even benefit from the reflection of sunlight off snow, which can increase their output. Additionally, advancements in technology and the use of anti-reflective coatings have improved the performance of solar panels in cold climates.
- Q: I know that the Solar panels store the power from the sun in the daytime, where does that stored energy go from there? Is it stored in the batteries? And how would you keep the batteries topped up if you had no Electric? by a generator? interested in solar panels for abroad, but need more info.
- Solar panels do not store power. Solar panels convert sunlight into electricity. To store power you need batteries. The usual type of batteries used are lead-acid deep discharge( similar to car batteries). The batteries are charged up during the time the sun is out. However, as a backup you could also have a generator handy to provide power for times when the sun did not shine enough to keep the batteries charged up.
- Q: How much space is required for installing solar panels?
- The amount of space required for installing solar panels depends on various factors such as the type and size of the panels, the energy needs of the property, and the efficiency of the panels. Generally, for residential installations, it is recommended to have around 100-400 square feet of roof space per kilowatt of solar panels. However, ground-mounted systems may require larger areas depending on the number of panels and their tilt angles. It is advisable to consult with a solar installer or expert to determine the exact space requirements for a specific project.
- Q: I was told by a veteran that jcpl had a program that installs free solar systems for disabled vets.If this is true who do i contact?
- yes. there is a free solar panel program for veterans.
- Q: i've heard that solar panel batteries have to be replaced withen 5-0 years. how much do solar panel batteries cost? please include sources!
- Depends on how big a battery you want and what technology. A lot of people use lead-acid batteries (rather like car batteries) and they do need replacing and 5 to 0 years isn't a bad estimate. However, the lead and lead salts content can easily be recycled into new batteries so its not as bad as it may seem.
