- Q: How do solar panels affect the appearance of a home or building?
- Solar panels can have a significant impact on the appearance of a home or building. They are typically installed on the roof, and their sleek and modern design can often enhance the aesthetic appeal of a property. However, some people may find the presence of solar panels less visually appealing, especially if they are not installed in a well-integrated or discreet manner. Ultimately, the effect on appearance depends on personal preferences and the design choices made during installation.
- Q: I am doing a report about solar power and I need to know what determines the amount of electricity produced?example: exposure to sun, angle of panel, qualityplease tell me as much as you canmuch appreciated
- It depends on what you mean by amount of electricity. Normally that would mean the total energy produced over a given period. In that case, the main factors are ) Efficiency of the solar cells 2) Total irradiation received: incident radiation density times the solar panel area, and the angle of the incident radiation. Item ) is determined by the materials and method of construction of the solar cells Item 2) depends on the location of the panel, both on earth's surface (latitude), time of year, and how the panel is oriented with respect to the horizontal. Altitude of the location can also be a factor. Prevailing weather conditions, number of cloudy days, etc. are important. Independent of these parameters, larger area means more electricity.
- Q: So during the day, electricity is on, everything is on and working fine. But at night where there is no sunlight does all the electricity shut down for the night? So there is no light on for me during the night, or I can't watch tv at night? Is it also true that with solar panels, your bills are less expensive. Can someone please tell me these things
- But at night where there is no sunlight does all the electricity shut down for the night? Electrical production shuts down, but most solar electric systems have some way of storing power. There are two main types of storage: . Grid tie. Basically this uses the power grid as a virtual battery. You produce extra power during sunlight hours to sell to the grid (other people use it) and you buy power from the grid when the sun doesn't shine. This is usually the most economical system, but whether you save money depends on a lot of things like: cost of installation, location, government subsidies how much you get for the electricity you sell buy. In other words, the details matter. Mostly location, which determines how much sunlight you get, electric rates, and subsidies. 2. Batteries. Usually a large bank of deep cycle lead acid batteries. Usually only used in off-grid systems and the cost of electricity is usually not competitive with grid electricity.
- Q: is a wind turbine better than solar panels
- is your place has enough wind or sunshine ? the turbine is not easily for maintenance. the solar panel is more stable, one broken panel willl not affect the whole system much
- Q: Can solar panels be used to power an air conditioning system?
- Yes, solar panels can be used to power an air conditioning system. Solar energy can be converted into electricity, which can then be used to power various appliances including air conditioning units. By harnessing the power of the sun, solar panels can provide a sustainable and cost-effective solution for cooling homes and buildings.
- Q: Is it possible for a 2V rated panel to charge a bank of batteries equal to around 36V? I believe that the panels should equal or exceed the voltage of the batteries but, I'm not for certain.
- With a 2 volt power source (solar panel, battery charger, vehicle charging system, etc...) you can charge three 2 volt batteries in parallel circuits then switch to a series circuit through a series/parallel switch to get 36 volts output. I've done this with my electric scooter so I can charge it with my pickup through the lighter socket when I'm away from home. It works great! When at home I just leave the switch in the 36 volt position, plug the charger in the wall receptacle and the charger puts out 36 volts. Actually 2 volt lead acid batteries have 2.6 volts when fully charged so the charging source has an output of 3.6 to 4.2 volts to effect a complete charge. In the series circuit the fully charged batteries would put out 37.8 volts so the charger would have an output of 40.8 to 42.6 volts.
- Q: Can solar panels be used in areas with high levels of salinity or brackish water?
- Yes, solar panels can be used in areas with high levels of salinity or brackish water. While exposure to saltwater can potentially cause corrosion and reduce the efficiency of solar panels over time, there are various measures that can be taken to mitigate these effects. These include selecting corrosion-resistant materials, applying protective coatings, and regular maintenance. Additionally, advancements in solar panel technology have led to the development of more robust and durable panels that can withstand harsh environments, including areas with high salinity or brackish water.
- Q: what is the average cost, for a single family home, to install solar panels? I live in CA.
- Just to be sure - when you say solar panels - are you thinking of hot water or electricity? For electrical power the system must photovoltaic.
- Q: Looking to install solar panels in my house.
- Wholesale prices for BP solar panels range between $335 for the 40 watts panel to $835 for the 70 watts panel. Here's a brief listing of wholesale prices for BP solar models: - BP340J solar panel (40 watts) @ $335 - BP350J solar panel (50 watts) @ $37 - BP375J solar panel (80 watts) @ $504 Right now I'm getting a series of 50 watt (7.5 volts) panels installed in my house. It's a start to reduce dependence on electricity bills and try get some tax rebates as well.
- Q: The inverter I am using gets the required 2 DC volts from the solar panel, but fo some reason it just won't output the 0 AC voltage. When the inverter is hooked to a car battery, it works just fine off the same 2 DC rating. Help me out please...
- There could be a couple of reasons why it isn't working. First, 2V panels actually put out a considerably higher voltage because it is presumed that they will be used to charge a 2Vdc battery. That requires applying a voltage greater than 2Vdc, and usually there is a solar controller that regulates the solar power to the battery. It also has a voltage drop. Look at the first reference reference, and you will see these values for a particular panel: Voc: 2.6V (open circuit voltage) Vmp: 7.2V (voltage at maximum power point) Voc is the voltage the panel produces under standard sunlight and temperature conditions (25°C), with no load applied. As load is applied, the voltage drops (see reference 2). Power is the product of current times voltage, so at one set of conditions (namely at Vmp) maximum power is available from the panel. Your inverter might not be working for either of two reasons: ) it has input protection circuitry that locks out operation when it senses an overvoltage, as in the 2.6V open circuit voltage, or 2) the panel does not produce enough current and the voltage from the panel collapses under excessive load. For example, if you load your inverter to 20W, then nominally the 2VDC input to the inverter must supply 20W/2V/eff = 0A/eff Assuming the inverter has an efficiency of 80%, the input current required is: 0A/.8 = 2.5A A solar panel operating at maximum power would need a rating of about: 2.5A x 7.2V = 25W Is your panel that big? The other option, as mentioned by others, is to charge a battery that runs the inverter. Other nuances: Voc increases as temperature decreases. Sunlight intensity varies (obviously), so the panel may produce less than rated power. The power specifications often are printed on the back side of the panel.
