Q: I have a rental property and use a 230-Volt 6-Amp Pool Pump.I would like to use a solar panel to run it when the house is empty, using mains power when guests are here.The building is in the Caribbean so plenty of sun!!I wanted to run it quot;directand not use batteries. Is this possible??What size panel would I need? A DC invertor too??Thanks!!: Why don't you use the mains as the battery with net metering. That way you don't have to have two pumps, a DC pump for the solar and an AC pump for the mains. A 230 V, 6 A pump draws 3.68 kw. A typical solar panel produces about 400 watts so you would need about 0 solar panels which should run you about $20,000 US. Of course, you may not need to run the pump continuously but in order to use fewer solar panels for sporadic use, you would need the batteries or the net metering. Keep in mind that with the costs of the panels, you will be paying about 38 cents a kwh. Grid power usually costs around 5 cents a kwh.

Q: I have several 6v 4.5a sealed lead acid batteries. I would like to hook one of them up to a solar panel and have it stay charged from the solar panel all the time, but not overcharged. Is there a simple way to do this with an IC or something? I am only a beginner with circuits so I want it to be something very easy to make. Basically, I want it to stay charged all the time so it's available if I need it for a power out or something.Thanks.: What I would suggest is that you find a panel that is rated for 00 mA, at any voltage higher than 8 volts. A 2 or even 8-volt panel will do, because the voltage will drop to match the battery. Then I would get a diode to put in series with the panel to prevent the battery from discharging through the panel at night. That's called a blocking diode. At such low currents, a charge controller is not worth it. There is not enough power to overheat the battery, which is principally what a charge controller protects against in a larger system. Be aware that you could also simply plug a trickle charger for the battery into the wall outlet, at a cost of less than a penny a day in electricity.

Q: . Does it really only cost $200 in contrast to $5000 or more?2. How much would it cost to build panels that would energize an entire average household? (washer, dryer, water heater, lights, fans, a/c)3. Is there a place to get the info on how to make them for free instead of paying E4E?4. Are the professional solar panels better? more efficient? 5. Will the electric company in So. Cal. really pay you?6. Do you have to be certified to do this professionally? or an electrician? If so what schools teach it?7. Would wind generators be of any use in So. Cal.? I mean don't you really need to get the fan spinning to get energy?8. Are there any extra unseen costs? (tools, energy converter, ect)9. How much is it to get an electrician to hook you to the grid?0. Is it better to hook to batteries or the grid? Pros, cons, why?: I believe Earth4Energy to be a bald-faced scam, selling plans that will not do what is implied in the marketing, and imparting no information that is not publicly available on the internet, already. If you were to search for solar panel on torrent sites, most likely, some disgruntled customer has posted the material. It probably violates the E4E copyright, so I'm not suggesting that you get it in this manner. I'm going to skip many of your questions, given my already-stated opinion of Earth4Energy. Professionally-installed panels have a net cost of thousands of dollars in general. While they can save money (and Southern Cal is an ideal place for this), consider that it generally takes 0 years or more to get your money back. If you're on S Cal Edison, or SD Gas and Electric, you can go on net metering. They don't really pay you, they credit your electric bill. After a year, if you used more electricity than you generated, you pay them. If you generated more than you used, they reset the balance to zero and say thanks for your donation. You never really get a check, like in some other states. But you should have lower electric bills. You can put up panels for your own use without any certification. To put up panels professionally, you'll need a C-0 contractor's license from the state, or will need to be under the supervision of someone with such a license. But if it's the latter, you might just be the grunt that carries the panels off the truck and up the ladder, for minimum wage. I'd say better than 95% of residentail solar is connected to the grid, if the grid is available. It's a clear winner. Who wants to pay 50% more for their system, just to have batteries that need their water and acid checked all the time? Below is one of many unsatisfied customers from Earth4Energy. Be careful in your search, people selling these reports have bought up the keywords such as scam and ripoff to direct you back to sites selling the product.

Q: how fast does a 25watt solar panel generate power to a battery? trying to figure out a conversion factor here to get a rough estimate of how many i would need to power my house, please help?: how fast? what does speed have to do with? Electricity travels at close to the speed of light. A house requires kW at a minimum, and 2 to 5 kW at peaks. You can do the division, 5000/25 = 40. Plus, solar panels operate only 4 to 8 hours a day in the winter, so you need to multiply that number by about at least 6 to allow for the dark hours. .

Q: I thought they were going to make solar powered cars and solar power plants among other things. It was only nearly 0 years ago that solar power was the big thing. Just curious, why did it die out?: I saw a commercial the other night for a fan you hook onto the top of your car window, and it's solar-powered. (supposedly cools off your car while gone...as opposed to just cracking the windows some). Also, I've seen traffic lights and emergency beacons on the highway powered by solar panels.

Q: I want to be more green and if I get the panels will I still have a regular electric bill?: The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.

Q: Do solar panels require a battery?: No, solar panels do not require a battery.

Q: Can solar panels be used on vehicles?: Yes, solar panels can be used on vehicles. They can be installed on the roof or the body of the vehicle to harness sunlight and convert it into electrical energy, which can be used to power various systems or charge the vehicle's battery. This technology is commonly used in electric and hybrid vehicles to improve their energy efficiency and reduce their carbon footprint.

Q: I got an 8v solar panel for a project today, the only problem is that it came without any wires attached to it. Now i don't know what type of wires i should use and if i should solder them on or if i should use epoxy instead. Can anybody help me out?: Most epoxy is not very conductive. I would go with solder.
