- Q: I am searching for producers or distributors of solar panels. Thanks!
- There are ton's of distributor around that can provide you a cheap solar panel that didn't came from China. Expand your knowledge and learn from a renowned solar company about the Best Solar Panels. Visit our site and contact us today!
- Q: I'm writing a post-apocalyptic story in it the main character finds a warehouse. Eventually he finds out the roof is covered with commercial solar panels. Given it's been over a year since the majority of the world died no manainence was done, do they still work?
- In my experience working with solar panels, I've found that the panels themselves are robust and can last years. How that energy is transferred from the panel to perform work (sorry for the boffinism) is where the complexity emerges, namely due to the fact solar panels produce DC current, and nearly all of our electrical appliances use AC current. In most cases, solar panels will either send energy through a DC/AC inverter directly to be used for appliances, or stored in deep cycle batteries, then converted to AC using an inverter when the user wants to use his/her appliance. Now to answer your question: the solar panels will be fine, and could conceivably be in fine working order with AC current available IF... and I cannot stress this enough (namely through years of field experience dealing with solar powered scientific instrumentation that was working well and then mysteriously not working)... IF rats and other rodents haven't eaten through the wires. This is probably the most likely reason that a set of solar panels wouldn't be working in your given scenario. Hope this helps, and good luck!!
- Q: I have an electric bicycle that I travel to work by, pulling a modified child carrying trailer that holds two 2 volt deep cycle batteries in series to power the 24 volt bike motor. I'm thinking about adding a 50 watt solar panel (or larger depending on the room I can make available) to charge while I'm at work and to provide some extra juice while on my more distant travels.Can I get a solar panel to charge them while they're connected the way they are: in series? Does charging work that way?I've read that in order to charge the 24 volt battery setup (if the answer to the Q above is yes), the output from my solar panel would need to be a little more than 24 volts. Is this true? If so, how many volts?Since the bike is supposed to be powered at 24 volts and I have an x-volt (x gt; 24v) solar panel connected to it, will this cause any damage to the controller or other components while running them?Will it help supply power even while the motor is being run?Thanks.
- Yes, you have it right you need two 2V panels wired in series to give 24V to charge a 24 volt system. But along with the 24V you also want some amperage, otherwise it takes forever to charge. Most of the little chargers are called trickle charges because they only have an amp or two. If you had two 25 watt solar panels putting out 24V you have : watts = volts * amps 50 watt = 24V * x amps x = 2 amps If your battery is say 50 amp hours of storage, then if you are putting in 2 amps it will take you 25 hours of sunlight to power it back up from a dead battery. So the charge time depends on how many amps you are putting in there at 24V A car battery charger typically charges at 0 amps at 2V, so 2 * 0 = 20 watts of power going in there So if you go solar make sure to use a charge controller and a big enough panel to get close to 00 watts for any decent recharge time. The charge controller makes sure that the battery only gets voltage going one way and it least 24V. So if the sun went behind some clouds and the voltage dropped to 20V, the controller shuts off the current until the voltage equals 24V or more
- Q: Can solar panels be installed on hiking trails or nature reserves?
- Yes, solar panels can be installed on hiking trails or nature reserves. However, certain considerations should be taken into account to minimize the environmental impact and ensure compatibility with the natural surroundings. Careful planning, appropriate technology, and consultation with relevant authorities are necessary to strike a balance between renewable energy generation and preservation of the ecosystem in these sensitive areas.
- 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: How do solar panels impact the local job market?
- Solar panels have a positive impact on the local job market as they create new employment opportunities in the renewable energy sector. The installation, maintenance, and manufacturing of solar panels require skilled workers, which leads to job growth and economic development in the community. Additionally, the transition to solar energy promotes a shift towards clean energy sources, attracting more investments and creating a sustainable job market for the future.
- Q: Can solar panels be installed on beach resorts?
- Yes, solar panels can be installed on beach resorts. In fact, beach resorts are an ideal location for solar panel installations due to their large open spaces, ample sunlight, and potential for reduced electricity costs. Installing solar panels on beach resorts can help them become more sustainable, reduce their carbon footprint, and contribute towards a cleaner and greener environment.
- Q: Can solar panels be installed on a warehouse or storage facility?
- Yes, solar panels can be installed on a warehouse or storage facility. In fact, warehouses and storage facilities are ideal locations for solar panel installations due to their large roof spaces and often minimal shading. Installing solar panels on these structures can help reduce energy costs, lower carbon footprint, and generate clean, renewable energy.
- Q: Can solar panels be used in areas with high levels of bird or bat activity?
- Yes, solar panels can be used in areas with high levels of bird or bat activity. However, to mitigate any potential risks to these animals, certain precautions can be taken. For example, incorporating bird deterrent features such as netting, spacing panels appropriately, or using specialized designs can help minimize bird or bat collisions. Additionally, conducting proper environmental impact assessments and considering local regulations can ensure the safe and responsible installation of solar panels in these areas.
- Q: Can solar panels be used in areas with high levels of noise from transportation?
- Yes, solar panels can be used in areas with high levels of noise from transportation. Noise pollution does not directly affect the functionality of solar panels as they primarily rely on sunlight to generate electricity. However, it is important to ensure that the installation of solar panels is done properly to avoid any physical damage caused by vibrations or other factors associated with transportation noise.
