- Q: During the summer my house uses about .47 kw/h I am wondering what solar panel do I need to cover most or all the electric bill. A link would be helpful too :)
- The correct answer depends on how much total energy you use during the day and whether or not your utility allows something called net-metering. In net-metering, if you make more power during daylight hours than you consume, the meter goes backwards. Then at night the meter goes forward again. With net-metering you only pay for the difference.
- Q: I'm just geting into electonics and stuff. So I am trying to make a simple USB charger. I'm looking for at least 4 volts output. What I've got is two solar panels (detached) a 4 AA battery holder, and a circuit board with an led on it (took the solar panels out of old lawn lights. I need more charge out of my panels (I think) so I tried attaching them. I soldered the positive wire from one to the positive connection on the other and negative wire to negative connection. After doing so and checking the multimeter, it says I have no output at all. How do you connect them?
- You have to look at the power output of the cell. The first consideration has to do with voltage. A single cell with no load might output one volt or less. Wiring cells in series would double that output, at least in theory. (Internal resistance will lower the actual voltage.) You've wired the cells in parallel, however. Try unsoldering one electrode and then measure voltage output of each cell. There is still the issue of current output. I don't know if there will be enough with your setup. How many cells are there and what kind of batteries were they charging?
- Q: I would like to know of any construction companies, road crews, or any company that uses solar panels in the Tampa area and throws them away. I like to recycle solar panels by repairing and processing what power I can from them. Know any companies that throw out used solar panels? If so, can you provide the name and number?
- Test the battery. Connect the positive and negative terminals of the battery to the positive and negative probes of the voltmeter. If a voltage is read, the battery is still good. Remember, however, that this is a rechargeable battery, so if it is dead, it can be recharged.
- Q: What are the financial benefits of installing solar panels?
- Installing solar panels can provide numerous financial benefits. Firstly, solar panels can significantly reduce or eliminate monthly electricity bills as they generate free and sustainable electricity from the sun. This can result in substantial long-term savings, especially in areas with high electricity rates. Moreover, solar panels often have a long lifespan, making them a worthwhile investment. Additionally, many governments and utility companies offer financial incentives such as tax credits, rebates, and net metering programs, further reducing the upfront cost and maximizing the financial return. Lastly, solar panels can increase the value of a property, making it more attractive to potential buyers and potentially yielding a higher resale value. Overall, by installing solar panels, individuals can save money, increase their property value, and contribute to a more sustainable future.
- Q: Can solar panels be installed on an agricultural greenhouse or nursery?
- Yes, solar panels can be installed on an agricultural greenhouse or nursery. In fact, it is a growing trend to incorporate renewable energy sources like solar panels in agricultural operations. Solar panels can provide a sustainable and cost-effective solution for powering greenhouse operations, reducing energy costs, and minimizing environmental impact. Additionally, the open space on greenhouse roofs or nearby land can be utilized for solar panel installations, making it an ideal option for farmers and nursery owners looking to adopt clean energy practices.
- Q: Can solar panels be installed on a gas station or fueling facility?
- Yes, solar panels can be installed on a gas station or fueling facility. In fact, many gas stations and fueling facilities have started installing solar panels as a means to reduce their carbon footprint and decrease their reliance on traditional energy sources. Solar panels can provide renewable energy to power the facility's operations, including lighting, pumps, and other electrical systems. Additionally, solar installations can help gas stations and fueling facilities save on electricity costs in the long run.
- Q: How are solar panels installed?
- Solar panels are typically installed on rooftops or open ground areas. First, the area is assessed for its solar potential. Then, mounting structures are installed securely on the roof or ground. Next, solar panels are attached to these structures and wired together in a series or parallel configuration. Finally, the panels are connected to an inverter that converts the DC electricity generated by the panels into AC electricity for use in homes or businesses.
- Q: i have a 50 watt 2 Volt solar panel..Will it can switch on directly a car head light on a sunny day??? How much head lights it can support on a bright sunny day??? if its cloudy then can it run a single Head light???? i have no batteries just want to connect a car Head light directly to solar panel.
- It should illuminate two auto headlights on a sunny day, if it really generates 50 watts at 2 V. On a cloudy day, I don't know. It depends on how cloudy it is.
- Q: How efficient are the solar panels....?
- Commercial monocrystalline panels are typically 8% efficient but inverters can be 65% to 90% efficient and lead acid batteries are 50% efficient at charging and 92% efficient at discharging plus they self-discharge at 3% to 20% per month.
- Q: I have an off-grid 24volt existing system using 8 x 80 watt 2volt, wired at 24volts, mono solar panels with deep cycle batteries,operating now. I have been given a 240 2volt polly cryst. panel. Can I add this panel to existing panels as above. Thank you, dumb solar man
- Assuming that you have / will upgrade wiring sizes to carry the extra wattage, that the new total wattage resulting from the addition doesn't overload any existing charge controller, diodes and / or inverter you have installed, then paralleling it straight into one of the other 2 volt groups should do nothing but add current to the system. True, it will be somewhat imbalanced, but it will work. Your other options would be to reconfigure everything down to it's native 2 V configuration which will raise current and lower voltage, with the additional panel creating the additional current to raise the wattage or to put it in series with the other 4 panel clusters so that you would get 36 V and additional current to account for the raised wattage. One last approach might be to set it up on another battery bank of it's own (small and at 2 V) to then connect to the same inverter. You'd be getting more power and storage capability that way, sort of a partial backup system, really, that will take some of the load off the other components to help extend their useful lives and get a bit more flexibility into it as well. The choice is yours here. That is all the ways that the system can be connected in, assuming everything in the first sentence checks out;-) It's difficult to make a recommendation without knowing what other components are in use and what the maximum ratings they carry are. Just remember that parallel connections add current and voltage stays the same, series connections add voltage and the current remains the same and you can figure out what to do with this thing to help you if you stay within maximum ratings for the charge controller, diodes and / or inverter involved. Good luck and stay safe!
