Q:When you add a load resistor to a PV panel (Solar panel) of 00 ohms what happens to the voltage produced from the cellAlso, as the resistance increases, how does this affect the output voltage: Photovoltaic cells have a load curve that gives the power conversion based on the current drawn. This makes it harder to calculate. For instance, at infinite resistance, the solar cell will have a peak voltage that produces no power (P=I*V=V^2/r). At short circuit, the voltage collapses to essentially nothing and so the power is almost nothing. There is an optimal load (sweet spot) where the resistance applied will draw the most power out of the cell while not overloading it. This measure is either given by the manufacturer or found experimentally. Upon taking a lit panel that has no load and applying a 00 ohm resistance, the voltage will drop. By how much is entirely dependent on the array layout and specific cell characteristics. As the resistance drops from the optimal load point, the voltage collapses fairly sharply. As the resistance increases from the optimal load point, the voltage will rise more at first and then level off to the peak or no-load voltage.

Q:i want to join multiple solar panels into a bank so i only need one length of wire, i am going to use diodes to stop them sending power back into the one before it. is this ok or do i need something else?: That depends on the product of solar panels you buy. I was recently talking to an installing company that sells solar panels that have the DC to AC built into each panel. That way you could simply string them together and add as much as you want as you can afford it. It really isn't much more expensive than any other method of install.

Q:Are the solar panels on the roof just a gimik to get all the tree huggers to buy it, or are they actually a good, efficent design?: The solar panel option is for running a ventilation system while the Prius is parked outdoors, so the sun won't heat up the interior. Personally I think it's a good idea, especially if your car has leather seats-- There is nothing more unpleasant than getting into a car with leather seats that has been sitting in the sun for hours with the windows closed. Many a people in shorts have their thighs scalded on the leather seats that way. The solar panels are a luxury option, not standard equipment on the Prius. I think luxury cars like Mercedes and Cadillacs with leather interiors can use a system like that.

Q:Can solar panels be installed on carports or other structures?: Yes, solar panels can be installed on carports or other structures. In fact, carports are a popular choice for solar panel installations as they provide an ideal location for capturing sunlight and also offer additional benefits such as shading for parked vehicles and protection from the elements. Installing solar panels on other structures like roofs or pergolas is also feasible, depending on the structural integrity and suitability of the location for harnessing solar energy.

Q:What is the principle of solar panels work?: light - heat - electric conversion method through the use of solar radiation generated by thermal energy, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The previous process is the light-heat conversion process; the latter process is the thermo-electrical conversion process.

Q:Are there any tax credits available for solar panel installation?: Yes, there are tax credits available for solar panel installation. The federal government offers a solar Investment Tax Credit (ITC), which allows homeowners to deduct a portion of the cost of installing a solar energy system from their federal taxes. Additionally, some states and local governments may offer additional tax incentives or rebates for solar panel installation.

Q:Can solar panels be installed on an agricultural greenhouse or nursery?: Yes, solar panels can be installed on an agricultural greenhouse or nursery. Installing solar panels on these structures can help offset energy costs and reduce reliance on traditional power sources. Additionally, it can contribute to sustainability efforts by harnessing renewable energy and reducing carbon emissions.

Q:Do solar panels float?: They'll float if you tie enough hundred dollar bills to them.

Q:Can solar panels be installed on museums or cultural centers?: Yes, solar panels can be installed on museums or cultural centers. In fact, many museums and cultural centers are adopting solar energy systems to reduce their carbon footprint and save on electricity costs. Solar panels can be installed on rooftops, parking lots, or even as shade structures, providing clean and renewable energy for the facility's operations.

Q:Harbor Freight sells a 75 watt solar panel, a surge power inverter, and deep charge batteries. But no one there can tell me how to put it all together. I want the end output to be a simple power bar that I can plug my devices into. I live in an apartment so I can not wire it directly into the grid. Please only serious responses. Don't waste your time and mine.: Solar Panel through charge controller to battery, battery to inverter, inverter to devices. a 75 watt panel would be enough to trickle charge a battery that is NOT being used to keep it at full charge. The average home requires 4000 watts MINIMUM. This would require MANY, LARGER panels, charge controller, a battery stack, and at least LARGER inverter (preferably 2, 2000 watt inverters, unless you want to REALLY get expensive!)
