Structure
A PV module is a packaged, connected assembly of typically 6×10 solar cells. Solar PV panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.
Feature
1. 10 years limited product warranty
2. 15 years at 90% of the minimal rated power output
3. 25 years at 80% of the minimal rated power output

- Q: I heard the wind turbines, solar panels so far provide America with around 2% of our energy. So since liberals appear to want to replace natural energy with man made products, that cause massive pollution by the way to make- How long will that take 30 years, 00 years? How many Wind Turbines will Airplanes and birds and parachute jumpers smash into, isn't that a problem? How do we rid of natural energy before we have the LIBERAL BACK UP PLAN - WE DON'T REALLY HAVE ? How do they think this is gonna work? Its not logical, we need to come up with more ideas! That Battery idea kinda sucks since Batteries Need natural energy to work.
- Green technology at this stage is not viable for the long run...we don't have the technology as of yet to replace all other modes of energy...Windmill Farms are EXTREMELY ugly and kills thousands of birds and only work when the wind is actually blowing...solar is not ready for prime time, too expensive for the average joe...we should be pursuing other engines that would use less gasoline and some exist but nobody is promoting those because they are convinced electric cars are the way to go but those are a farce because we don't generate enough electricity now for homes to use, can you imagine how little we would have if all cars starting using that same energy? IT is a farce that during an economic crisis the current powers that be are wasting money on green technology garbage that won't work. We should be figuring out how to drill our own oil and get off foreign sources and build more plants to produce more electricity, not figure out how to use the little electricity we currently produce in all our vehicles...Liberals...what a concept.
- Q: Can solar panels be used for charging electric bicycles?
- Yes, solar panels can be used for charging electric bicycles. By connecting the solar panels to a charge controller and then to the electric bicycle's battery, the energy from the sun can be converted into electrical energy to charge the bike's battery. This allows for a sustainable and renewable way of charging electric bicycles.
- Q: Can solar panels be installed on public parks or gardens?
- Yes, solar panels can be installed on public parks or gardens. In fact, it is becoming increasingly common to see solar panels integrated into the design of these spaces. Installing solar panels in public parks and gardens can help generate clean energy, reduce carbon emissions, and provide shade and shelter for visitors.
- Q: Can solar panels be installed on a condominium or apartment building?
- Yes, solar panels can be installed on a condominium or apartment building. However, it may require certain considerations such as the availability of suitable roof space, permissions from the building owners or management, and potential impact on other residents. Additionally, installation and maintenance costs may need to be shared among tenants or considered in the building's budget.
- Q: Polycrystalline solar panels are good or single crystal solar energy is good
- From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
- Q: Can solar panels be installed on outdoor event venues?
- Yes, solar panels can be installed on outdoor event venues. In fact, outdoor event venues are often ideal locations for solar panel installations as they provide ample sunlight exposure. Installing solar panels can help event venues generate clean and sustainable energy, reducing their reliance on traditional power sources and lowering their carbon footprint.
- Q: I riped two solar panels out of some solar light and tested them. I found out that they both produce 2 volts(I have no idea on the watts or amps). Iquot;ve hooked them up to an electric motor that can be driven by a AA battery, but when I hook the solar panels up to them nothing happens. What is wrong?
- The solar cells you have are not providing enough current to operate the motor. There are special low power motors which can operate directly from a solar cell but it sounds like you do not have one of these. Instead you have a common .5V DC hobby motor which requires substantially more current to operate. You can use the original circuit to charge the batteries and use the charged batteries to run the motor. The batteries would be able to supply enough current to operate the motor, but for a limited time. 8 hours of charging might give you less than 5 minutes of motor operation. An LED will draw about 20ma. In a solar light such a small current draw from an LED or two can provide hours of light. A Small DC motor might easily require 300ma to run and over 500ma to start. Running a motor from the same battery at over 5 times the current draw will result in less than /5 of the run time compared to the low current LED. So if an LED operates for 300 minutes the motor would run for less than 20.... The small solar cell size cannot provide enough current to operate the motor directly. Only by slowly charging a battery first would you be able to use the collected and stored Solar energy to operate your motor.
- Q: How do solar panels affect the environment?
- Solar panels have a positive impact on the environment as they produce clean and renewable energy, reducing the need for fossil fuels. They help decrease greenhouse gas emissions, air pollution, and water usage associated with traditional energy sources. However, the production and disposal of solar panels can have some environmental impact, including the use of certain materials and energy during manufacturing. Overall, their benefits outweigh the potential drawbacks.
- Q: I have an off-grid 24volt existing system using 8 x 80 watt 2volt, wired at 24volts, mono solar panels with deep cycle batteries,operating now. I have been given a 240 2volt polly cryst. panel. Can I add this panel to existing panels as above. Thank you, dumb solar man
- Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
