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: I have a 500 watt inverter and battery but need solar panels to run my need. I want to have enough juice to run a computer and monitor and sometimes a 5w amp. I am not sure how much power is needed to run the computer (standard desktop with 5flat screen with an additional surround sound system) though on the side of the computer it says 5 amp but I know I used to run it and monitor and surround sound with a heating blanket on the same circuit which was rated at 20 amps. My question is that I would like to go and buy some panels (cheaply as I'm unemployed) from somewhere like Harbor Freight that would meet the need of the converter to supply enough amperage. So what size panel(s) or panels would I need to run this setup? If I am correct I think 500 watts is equal to 5 amps. Would this even work? Could I run a partial system where I could run some of the stuff to take a load off? I need to lower my electric bill somehow. Thanks!: Solar okorder in their survival discussion in the archive, this exact project was discussed at length.

Q: Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.: There okorder Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!

Q: please no dumb answers and list where you got the info.Also how much does it cost to install solar panels for a regular sized house?: Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .

Q: Can solar panels be installed on a gas station or convenience store?: Yes, solar panels can be installed on a gas station or convenience store. Installing solar panels on these establishments can help offset their energy consumption and reduce their carbon footprint. Additionally, it can lead to cost savings in the long run by generating clean and renewable energy.

Q: What is the lifespan of solar panel batteries?: The lifespan of solar panel batteries can vary depending on various factors such as the type of battery, its quality, and usage patterns. Generally, solar panel batteries are designed to last between 5 to 15 years. However, with proper maintenance and care, some batteries have been known to last even longer.

Q: Can solar panels be used in remote areas without access to the grid?: Yes, solar panels can be used in remote areas without access to the grid. Solar panels generate electricity by harnessing sunlight, and they can operate independently of the grid. This makes them an ideal solution for remote areas where setting up power lines and accessing the grid may be difficult or costly. Solar panels can provide a reliable and sustainable source of electricity in such areas, allowing for various applications like powering homes, schools, clinics, and even small businesses.

Q: how long till a 50 watt solar panel pays itself off in buffalo, ny if its $500. i have national grid and heres the link to the rates. i am residential.: lots of info about solar panels, perhaps you'll find answer to your question renewableenergyarticles.blogspot....

Q: Aren't batteries bad for the environment?Toxic?Expensive? With small solar panels phones, iPod's, laptops other small electronics could be smaller, slimmer, more efficient cost people less to charge every day. Maybe a small battery inside as a backup and to store the Solar energy for night time. But overall, batteries should be optional. So big question:Why aren't electronics being produced with solar panels?: Solar panels could still be expensive, which would also raise the cost of the item.They also are made with chemicals that harm that enviroment(not too badly, but ya know..) You would also need to charge them, of course, in sunlight and most people enjoy the benefit being able to plug something in and still being able to use it. Not saying it's a bad idea, just the world we live in.

Q: Can solar panels be used for powering an electric fence?: Yes, solar panels can be used to power an electric fence. Solar panels can generate electricity from sunlight, which can then be stored in batteries or directly used to power electrical devices, including electric fences. This allows for a sustainable and independent power source for electric fences, especially in remote areas where access to traditional power grids may be limited.
