Q: How will i construct solar panel?
The first step to planning your system is to evaluate rebate options and obtain permits. Deciding the size of your system is the next step. With a grid-tied system, size is less critical, because the grid supplies power when your PV system falls short. Systems as small as a couple hundred watts are practical, but you can also install panels that will produce enough electricity for all your needs.
Q: What Are Solar Panels Made Of?
Create okorder /
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?
While you can measure voltage on a like without a load, the measure of amperage is more closely related to the amount of power that is being drawn. The amperage is measured with the meter in series (not parallel like voltage) with the load. What it ends up measuring is the load that is being drawn from the solar panel and not the potential of the panel.
Q: Can solar panels be installed on a rental property?
Yes, solar panels can be installed on a rental property, but it would require permission from the property owner or landlord.
Q: Can solar panels be installed on shopping malls or retail centers?
Yes, solar panels can be installed on shopping malls or retail centers. In fact, many commercial buildings are increasingly adopting solar energy systems to reduce their carbon footprint and save on electricity costs. Installing solar panels on shopping malls or retail centers can provide a sustainable and renewable energy source, contributing to their overall green initiatives.
Q: What is the impact of bird droppings on solar panels?
Bird droppings can have a negative impact on solar panels as they can reduce the efficiency of the panels by blocking sunlight. The droppings can create shadows and reduce the amount of sunlight that reaches the panels, leading to decreased energy production. Additionally, the acidic nature of bird droppings can damage the surface of the panels if not cleaned regularly, potentially reducing their lifespan. Therefore, it is important to regularly clean and maintain solar panels to ensure optimal performance and longevity.
Q: Can I add reflectors or mirrors around the solar panels to increase the power they generate?
In the 70's when silicon was really expensive, they played with using fresnel lenses to focus the sunlight on small solar cells but these panels had to be on heliostats and aimed directly at the Sun. These days, with nano-technology, there's a renewed interest in the concept but the fundamental weakness is that there are diminishing returns, at some point, it's just less expensive to have more solar cells.
Q: I'm trying to charge rechargeable AA batteries with a solar panel. What gauge wire should I use to connect the panel to the batteries? I know I'm not going to have a lot of current going through so the wire size doesn't really matter. Can the wire be too thick thoShould I ugh? Should I use a diode to keep the batteries from overpowering the circuit? If so, what size diode? My panel is 4.8V 50mA. Can I just hook the panel straight into the batteries or do I need something else?
In order: .? Just about any wire will do.? You can handle 50 mA over just about anything, even 28 gauge telephone wire.? Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.? You need a diode.? If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.? The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.? You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.? This gives you maximum current output from your panel.
Q: Are there any government incentives for installing solar panels?
Yes, there are various government incentives available for installing solar panels. These incentives can include tax credits, grants, and rebates provided by federal, state, and local governments. These programs aim to promote the adoption of renewable energy sources and help reduce energy costs for homeowners and businesses.
Q: Can I use a regulator from a car to regulate the voltage from a solar panel to a battery?
solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
