4. Q: Can the price be cheaper?

A: Of course, you will be offered a good discount for big amount.

Q:How do solar panel power systems work?: The panels soak up the energy from the sun and then convert the energy into power, electricity, etc. They can also store a lot of energy so that we still have power on cloudy days. Does that help? Without more info, its hard to get more specific.

Q:If I wanted to add solar panels to my home to produce on average, 8 kWh of electricity daily, how much do you estimate it would cost using state of the art technology?I live in Virginia (Washington DC Metro Area), and I have Dominion Power. I pay the following electric rates:Jun-Sep $0.0904/kWhOct-May $0.0776/kWhAnnual Ave: $0.0824/kWhDistribution charges add on approximately another $0.0228/kWh.How long would the ROI for an 8 kWh/day solar system be?: Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .

Q:Can solar panels be installed on a tennis court or sports complex?: Yes, solar panels can be installed on a tennis court or sports complex. The large open spaces and flat rooftops typically found in these areas make them suitable for solar panel installation. This can help generate clean and renewable energy while also reducing the electricity costs of the facility.

Q:How much space is required for solar panel installation?: The amount of space required for solar panel installation varies depending on factors such as the size and type of panels used, as well as the energy needs of the property. On average, a residential solar panel system typically requires about 100-400 square feet of roof space per kilowatt of installed solar capacity. Additionally, ground-mounted systems may require larger areas, typically ranging from a few hundred to several thousand square feet depending on the system size. However, it is important to consult with a professional solar installer to determine the specific space requirements for your individual project.

Q:So you know how the bigger the surface area exposed to the heat radiation means the quicker it'll heat up.Is this what happens with solar panels, they have a large surface area exposing to the sun, so they can get more heat?: Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.

Q:Can solar panels be installed in urban areas with limited space?: Yes, solar panels can be installed in urban areas with limited space. There are various options available such as rooftop solar panels, building-integrated photovoltaics, and solar canopies that can be used to maximize the utilization of available space in urban areas. Additionally, advancements in solar technology have led to the development of more compact and efficient solar panels, making it easier to install them in limited spaces.

Q:How long does it take a 5 watt, 2 volt solar panel to charge a 2 volt R.V. battery?: Homemade okorder

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.

Q:And how do you choose the best one for the best price?I saw a 400 watt monocrystalline solar panel: The polycrystalline solar panel has a longer life-span and has a higher efficiency. What this means is that from the energy that 'hits' the solar panel, more is caught and used to convert into electrical energy. A polycrystalline solar panel will have an efficiency of about 4%. The monocrystalline solar panel has a similar efficiency but the cells are prone to sunlight, so the efficiency drops over the years.

Q:Can solar panels be installed on greenhouses?: Yes, solar panels can be installed on greenhouses. In fact, it is a popular practice as it allows for dual benefits - generating clean energy while also providing shade and protection to the plants inside the greenhouse.
