- Q: what do I need to do to disconnect a solar panel from a battery to protect the panel?
- Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
- Q: Hello, I have been trying to go green, I Have purchase somesolar panel they are about 45watts I been putting it against my window and getting ok power out of it enough for my lights and a couple of low watts gadget (cellphone, 2v light, portable dvd) for couple of hours.But its seem to drain the 2v faster then I can charge Am I getting the most power out of my panel?Or should I place it on the roof? I'm in Texas and it gets hot and sunny the sun beam my room windows pretty good during 4pm-6pm.
- It will generate MUCH more current if placed outside of the window. The best position is pointing directly south. Over the period of one day, you will get the most average sunlight pointing in that direction.
- Q: How do solar panels affect the property's energy consumption?
- Solar panels can significantly reduce a property's energy consumption by generating electricity from sunlight, thereby offsetting the need to draw power from the grid. This helps to lower utility bills and decrease reliance on fossil fuels, leading to both financial and environmental benefits.
- Q: Didnt solar panels use to cost around $250,000 5 years ago?
- I okorder to register for free and lock in long term costs. The increasing demand and competition is helping reduce costs.
- Q: Please, I want a good definition. :DD
- The previous answer stating that a solar panel is a method of collecting, and converting sunlight into electricity is correct, however once sunlight has been converted into electricity, it has to have a way to be stored, so that it can be used. This is accomplished by the use of storage batteries. It is stored in a DC or Direct Current form, and may then be converted to AC (alternating current) through the use of an inverter.
- Q: Hi.How efficienent are solar panels? I mean, suppose we install a kw panel.. Wil it produce 5kw in 5 hours of good sun light?Or like if its 80 percent efficient, wil it produce 4kw and so on.Also, do the chinese solar panels give the same results as compared with panels from other countries?I live in india, so we get plenty of sunlight during the day.Thanks

- Q: Can solar panels be installed in areas with high wind speeds?
- Yes, solar panels can be installed in areas with high wind speeds. However, it is important to ensure that the solar panel mounting systems are designed and installed properly to withstand the strong winds. This may involve using appropriate mounting techniques, securing the panels firmly, and considering the orientation and tilt angles to minimize the impact of wind resistance.
- Q: How do solar panels affect roof maintenance?
- Solar panels can have both positive and negative effects on roof maintenance. On the positive side, solar panels can provide an added layer of protection to the roof by shielding it from harmful elements like UV rays, rain, and snow. This can help extend the lifespan of the roof and reduce the need for repairs. However, solar panels can also make roof maintenance more challenging as they need to be regularly cleaned and inspected to ensure optimal performance. Additionally, any repairs or maintenance work on the roof may require temporarily removing the panels, adding an extra step to the process.
- 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.
- I don't have direct experience with the Harbor Freight panels, but have heard that they are agressively rated - i.e., the three 5-watt panels are really 5-watt panels. The 80-watt panel is likely to be a serious panel, rated according to standard test conditions. It will also be more durable, and probably have a warranty of 20 years or more. There's really no comparison. If your goal is to experiment with solar electricity, then get the kit from Harbor Freight (or Northern Tool, or any of a handful of other places). If your goal is to save money, generally you will need a larger scale than 80 watts - several thousand watts being the norm. And the payback time will be measured in years.
- Q: My plans are building several solar panels and have a battery bank. I want to be able to power the refriderator and freezer and occationaly an electric grill. How would This work exactly and what would the best way to hook this up to make it work? I want to be able to convert DC to AC. How many batterys would I need to make this work. I know when Civil unrest happens I want to be prepared. How would Wind Power work If I can get the equipment I need?
- Solar panels and wind/water turbines all produce the energy and feed it into the batteries. Outfeed from the batteries thru an inverter to an electrical panel. From panel to outlets, into which you plug standard appliances and items. You can also get some appliances that run off of 2volt. Check with r.v. companies and suppliers for these. You can also run low voltage wires straight from batteries to switches to lights, fans, etc if you put in 2v ones. Just like your car has lights, fans (ac blower), and radio. As for how many batteries you need will depend upon how much ebergy you will use. You will need to figure how much all of your items use per hour. Then figure how long your charging device could be down for at a time. Solar panels will not charge at all for the 8-2 hours of nightfall depending on your area. Wind turbines will charge day and night so long as wind is of sufficient speed. Water turbines will charge 24/7 so long as water source(creek, stream, river) doesn't run dry. Neccessity/hr=N, time without charging =T. N times T = the amount of backup power you need to get you thru till charging sysytem kicks back in.
