- Q:how much would you pay for a 2'x4' solar panel that puts out 24 volts and 74 watts?
- That's a rather low power for that size. Is it an old panel? Is it amorphous silicon, or crystalline? That should easily fetch $ per watt on craigslist. If I was buying a panel myself, I would probably get a more mainstream panel from a major internet vendor.
- Q:i need how a solar panel works, if possible make as easy to understand as possible like because of this , this happens and if you could please put a web source you got it from
- How okorder /... Use the next page link to flip through the article.
- Q:Can solar panels be used to power an entire office building?
- Yes, solar panels can be used to power an entire office building. By installing a sufficient number of solar panels on the roof or surrounding areas, an office building can generate enough electricity to meet its energy needs. Additionally, by integrating battery storage systems, excess solar energy can be stored and used during non-sunlight hours, ensuring continuous power supply.
- Q:Can solar panels be used in areas with high wind speeds?
- Yes, solar panels can be used in areas with high wind speeds. However, it is important to ensure that the solar panel installation is designed and engineered to withstand the specific wind conditions in the area. This may involve using specialized mounting systems and ensuring proper anchoring and structural reinforcement to prevent damage or dislodgement due to strong winds.
- Q:I have 2 20 watt Solar panel. I have it hooked up to solar controller and batteries to inverter. Am trying to figure out how much watts am getting. I found the voltage but how do I find the amp reading on a mutimeter?
- It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.
- Q:Do solar panels require regular cleaning?
- Yes, solar panels do require regular cleaning to maintain optimal performance. Accumulation of dust, dirt, leaves, bird droppings, and other debris can reduce the efficiency of the panels. Regular cleaning, either by homeowners or professional services, helps ensure maximum sunlight absorption and energy production.
- Q:Can solar panels be used for powering an electric fence?
- Yes, solar panels can be used to power an electric fence. Solar panels can generate electricity from sunlight, which can then be stored in batteries or directly used to power electrical devices, including electric fences. This allows for a sustainable and independent power source for electric fences, especially in remote areas where access to traditional power grids may be limited.
- Q:Are there any limitations to the lifespan of solar panels?
- Yes, there are limitations to the lifespan of solar panels. Over time, solar panels experience a gradual decrease in efficiency due to factors like exposure to environmental elements, wear and tear, and potential manufacturing defects. Additionally, the materials used in solar panels may degrade over time, which can affect their performance and overall lifespan. However, with proper maintenance and regular inspections, solar panels can typically last for 25 to 30 years or even longer.
- Q:OK, so if you put solar panels up on a roof, they are busy turning the sun's energy into electricity. So, does that mean the roof (and therefore the house/structure) stays cooler as well? Or does it still get hot, because . . . I dunno, maybe the panels don't convert all the energy, and the spillover still heats up the building.Any links or URLs to scientific answers would be appreciated, but I don't mind hearing from the Average Joe or (Joelle).
- I asked the same question once to a PV install during a seminar a few years back, and he explained the following: No, PV panels do not reflect or absorb much heat from going into the building below but there is a reason for this: PV panels that reflect / absorb heat produce less electricity. They are designed to Thermally Transparent. Even worse if installed incorrectly without a good angle and air gap to allow the heat to escape the panels will actually trap this heat and increase the interior temperature of the building below! Below is the scientific analysis that is quite verbose but has two nice graphs at the end. To summarize: Adding PV panels, at best, shaded the building enough to reduce the load of the interior A/C unit by .8 kWh/sq-m/year. The electricity generated by the panels was about 356 kWh/sq-m/year. You can see the big advantage of PV panels is to make power, not reflect heat. Proper insulation is much cheaper and will do a much better job. Don’t worry, I was shocked too, but like anything it makes sense after it is explained.
- Q:How much energy can a solar panel produce?
- The amount of energy a solar panel can produce depends on several factors, including its size, efficiency, and location. On average, a residential solar panel system can generate anywhere from 10 to 20 kilowatt-hours (kWh) of electricity per square meter per day. However, this can vary significantly based on sunlight availability, panel orientation, and weather conditions.
