- 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?
- Leave the two positive terminals connected together.Disconnect the negative leads from each other. Get two amp diodes from radio shack. Connect each diode in series with each negative lead. there is a band on one end of the diode. Connect each diode so that the end with the band is attached to the negative side of each solar panel. Tie the other ends of the diodes together. This will become the new negative end of your solar panel supply. With the sun shining on the panels , you will now measure the voltage from the plus side of the solar panels to the new negative junction. Connect your load leds in place of the voltmeter and enjoy. Without the diodes , each solar cell thinks the other solar cell is the load. In effect each solar panel is shorting out the other. Some solar panels that you buy already have a diode in their junction box connected for that purpose. You need the diodes to provide the necessary isolation between the two panels, then they can both act in parallel to provide current to the load.
- Q: what are solar panels?
- Solar Panels collect solar energy from the sun and then solar energy is used to produce electricity.
- Q: I am looking to get some solar panels for my home to just power a few lights, a fan or two. I have a generator but I want that only to power the fridge and maybe some other small stuff for convenience.But mainly want the solar panels for the lights and fans. Any one have an idea of how about I go to figuring this all out? Should I call a contractor or anything?
- If your only deed is for power during outages, solar is not the way to go. You can add up all the wattages of the fridge and the lights you want to use, and see if the total is less than the capacity of the generator. If it is more, buying a larger generator is the answer. You can find the wattage of the fridge on the inside, or back. If not, Google the model number and manufacturer. You may already use CFL light bulbs, but if not, they can help reduce the load.
- Q: Im doing a project and i have to persuade some one that solar pannels are great... help ?
- Solar panels saves energy (electricity) because the power comes straight from the sun and stuff
- Q: Can solar panels be installed on factories or manufacturing facilities?
- Yes, solar panels can be installed on factories or manufacturing facilities. In fact, many industrial buildings are ideal for solar panel installations due to their large roof space and high energy consumption. Installing solar panels on such facilities can help reduce electricity costs, decrease reliance on traditional energy sources, and contribute to a more sustainable and environmentally friendly operation.
- Q: Can solar panels be installed on a canopy or pergola?
- Yes, solar panels can be installed on a canopy or pergola. In fact, installing solar panels on these structures can provide dual benefits, offering shade and generating renewable energy simultaneously. This innovative approach allows for the efficient utilization of space and can be a great solution for homeowners or businesses looking to maximize their solar energy production while enhancing their outdoor living spaces.
- Q: How are solar panels installed?
- Solar panels are typically installed on rooftops or open spaces using metal frames or mounting brackets. The process involves anchoring the panels securely, connecting them in a series or parallel configuration, and wiring them to an inverter that converts the DC electricity generated by the panels into usable AC electricity. Additionally, a solar panel installation may require making electrical connections to the building's electrical system and installing a net meter to measure the energy produced and consumed.
- Q: I would like a list of the solar companies expanding or doing hiring or a good list in general. I know some are expanding. Best answer gets all the points

- Q: Are solar panels fire hazards?
- Solar panels are generally not considered fire hazards. While there have been some isolated incidents of fires related to solar panels, they are extremely rare and typically caused by faulty installations, damaged equipment, or external factors. When installed properly and maintained regularly, solar panels pose no significant fire risk.
- Q: For example, If I were powering my house with solar panels, would it be more efficient or effective, (or I guess would I get more energy) out of a day that measured 90 degrees Fahrenheit as opposed to a day that is 70 degrees Fahrenheit.
- Not at all. You`ll generate more energy on a clear sunny day in the winter time than you would on a cloudy day in the summer.
