Characteristics of Solar Panel
I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.
II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.
III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water
IV AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.
V Junction box: Multi function junction box with water proof.
VI Long lifetime: ≥25 years; Less power decrease.
VII Good performance of preventing from atrocious weather such as wind and hails.
VIII Resisting moisture and etching effectively, not effected by geology.
Currently,We have 250w-300w solar panel stocks in Both West and East Coasts made in Vietnam,India,Korea,Malaysia and Japan.Meanwhile,we also arrange production line in Wisconsin,USA.If you're interested,please contact us soon.
Thanks for your time.
- Q: I heard that solar energy has a lot of advantages but are there any drawbacks in using the solar panels?
- I guess the main thing is to look out for the warranty like where the warranty is claimed and the process of claim, how efficient the inverter of the system is and also make sure you are getting value for your money.
- Q: Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair?Thanks.
- bypass the whole panel if you can ( one individual panel of several ) , or bypass that loop in that panel - car part rubber hose clamps
- Q: The Physics club in our school is trying to convince the Board of Ed to install solar panels in our school, and i was just wondering if anyone with some experience or real expertise in solar energy. I need some points about their usefulness some real pros and cons on maintenance, etc. Anything will help. Personally i would be perfectly for the idea, but i heard that the overall cost of installing them is much higher than the cost of the energy saved and government subsidies, but ive only heard about this.
- You have to approach it as an investment. Ignoring the cost of an inverter for net metering, if we consider a 500 W panel installed for $0 a watt which is $5,000 and consider an average of 8 hours of usable sunlight per day, and at a rate of $0.0 per kWh (schools probably get $0.03 per kWh) then the panel would be saving $2.7 per month in electricity. Considering that the panel has an expected lifespan of 20 years, that would give you an internal rate of return such that the monthly rate satisfies the equation: $5,000 = $2.7 * ( ( - / R^24 ) / ( - / R ) - ) By binary method we get R = 0.99588342. Taking this to the 2th power to annualize it we get Ra = 0.9570 which means that we are getting an annual return of -4.83% per annum so investing in the solar panel is the same as making an investment at an interest rate of -4.83% per year. True interest rates are low and you only get about .3% per annum by putting money in a CD but that still beats investing in solar panels which gives you a negative return on your money. Solar panels need to get a lot better before they are a good investment.
- Q: If I wanted to put some solar panels on my roof, how many would i need and how many watts would they have to be to be able to power my whole house?
- Actually even if you cover your whole roof with panels, you wont get enugh power to even run a tv, fan and light at the same time. Solar panels give out a very less power output.
- Q: I have an inverter and a battery 20 Amperes.Daily sun shine approx. 7 Hours.Do I need to buy anything or should I connect the solar panel to the Battery direct?
- No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)
- Q: Can solar panels be used in off-grid systems?
- Yes, solar panels can definitely be used in off-grid systems. In fact, they are a popular and reliable choice for generating electricity in remote locations where access to the traditional power grid is limited or non-existent. Off-grid solar systems store excess energy in batteries, ensuring a continuous power supply even during periods of low sunlight.
- Q: Would it be possible to use a lens or a mirror to focus light onto a solar panel in order to make in more efficient? And is something like this already being used? It was just a thought and I haven't spent much time on it, but I figured I'd ask.
- yes it is being done. i've seen adds for such a system. on the other hand, if you had a 5 sq in Lens focused on a small cell, and a 5 sq in cell, they'd be about the same. in fact, the cell might be a bit better because (A) there wouldn't be any loss in the Lens, and (B) it might be that the solar cell would use some frequencies to which the Lens was opaque. in addition, the cost of solar cells is dropping, making the cost of the mirrors or lenses uneconomical by comparison.
- Q: How do solar panels affect the property taxes?
- Solar panels can potentially affect property taxes in a couple of ways. In some states or localities, installing solar panels may increase the assessed value of a property, leading to higher property taxes. However, other jurisdictions offer exemptions or incentives that can reduce or eliminate the increase in property taxes associated with solar panel installations. It is advisable to consult with local tax authorities or experts to understand the specific impact on property taxes in a particular area.
- Q: I really need to know about the good companies who are selling good quality home solar panels.I lives in Pakistan, solar panels sell here are cheap but they doesn't work for long time, mostly they are quot;made in chinaquot;.Consumption of units of our house written on our electricity bill is 300.My dad is seriously thinking of purchasing a solar energy system for house that long last and works efficiently.So plz help me out.
- reckoning on the place you reside, the mixture of federal, state and city tax credit and rebates can offset the cost of photograph voltaic panels appreciably. however, till you utilize fairly some electrical energy, it ought to take some years for the panels to pay for themselves. you're truly paying for your electrical energy beforehand. The extra you utilize and the extra it expenses according to kW/hr, the speedier the cost would be offset by employing the mark downs. do no longer setting up photograph voltaic panels on a house you're renting or one which you will possibly sell contained in right here couple of years. it is not functional to un-setting up them and pass them to a clean homestead. power conservation is a thank you to cut back your enery expenditures with the backside up front cost. in case you have no longer had an power audit, see in the adventure that your power provider does them at low or free of charge. setting up timers on air conditioner thermostats. in case you have electric powered water heating, have a timer put in on that besides. Water heating is between the main important power wasters available. Why save the entire tank of water warm once you basically use it interior the morning to bathe? in case you have your heart set on having photograph voltaic panels yet can no longer handle to pay for the upfront cost, analyze the companies that do installations on your section. some have hire and hire/purchase innovations now.
