- Q: Can solar panels be installed in urban areas with limited space?
- Yes, solar panels can be installed in urban areas with limited space. There are various innovative solutions available, such as rooftop solar panels, solar canopies, and solar facades, which can be utilized to make the most of the available space in urban environments. Additionally, advancements in solar technology have made it possible to install more efficient and compact solar panels, further facilitating their installation in limited spaces.
- Q: I want to buy a solar panel to charge deep cycle batteries and charge electronics off the DCB. I don't know how to wire everything up though or what materials ill need. Inverter? Gauge of the wire? Ampmeter?
- the solar panel should state it, you dont need a inverter to charge, only to use the power from the cell.you do need an amp regulator, so it tells if the battery is on full charge and so the sun doesnt over power the battery through the solar panel
- Q: How much does it cost to replace a solar panel?
- The cost of replacing a solar panel can vary depending on several factors such as the size, type, and quality of the panel, as well as any additional installation or labor costs. On average, the cost can range from a few hundred dollars for a small residential panel to several thousand dollars for a larger commercial panel. It is always best to consult with a solar panel installer or supplier to get an accurate estimate based on your specific needs and requirements.
- 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 government building or facility?
- Yes, solar panels can be installed on a government building or facility. In fact, many government entities have already started incorporating solar energy as a sustainable and cost-effective solution to meet their energy needs. Solar panels not only help reduce carbon emissions but also provide long-term savings on electricity bills.
- Q: Actually I want to convert my home electricity on Solar Panel to cut down electricity costI have 2 AC's, a refrigerator, 3 Television, 2 Computers, 4 Fans etc
- good okorder lots of good ideas there
- Q: Do solar panels work at night?
- No, solar panels do not work at night because they require sunlight to generate electricity.
- Q: how does solar panels work?
- Solar panels collect solar radiation from the sun and actively convert that energy to electricity. Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy. The energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their orbits and released, and electric fields in the solar cells pull these free electrons in a directional current, from which metal contacts in the solar cell can generate electricity. The more solar cells in a solar panel and the higher the quality of the solar cells, the more total electrical output the solar panel can produce. The conversion of sunlight to usable electrical energy has been dubbed the Photovoltaic Effect. The photovoltaic effect arises from the properties of the p-n junction diode, as such there are no moving parts in a solar panel.
- Q: What is a good sight that I could go to about installing solar panels and all of the considerations of it?
- Biggest problem is availability of sunshine in the UK. Do you get enough to warrant the fuss or financial layout? Another problem is the orientation of your roof. Facing directly south, with a slope (in degrees) equal to your longitude would be ideal. As far as electricity goes, you have to be tied into the grid to take care of the times you are not generating all the power you need. When you are generating more than you need, you sell it but get paid at the rate the utility normally pays, a lot less than you would pay to buy from them. Still, it's something.
- Q: when building a solar panel should the diode be on the positive or negative sidelittle more detail i just built a solar panel and im running it to a grid tie converter should i put diodes in if i add another panel or are they only for battery systems?
- Bypass diodes would be in parallel with groups of solar cells in a panel. For example, if a module has 72 cells, maybe every 8 cells, there will be a bypass diode. A bypass diode does nothing except salvage some of the energy from the panel if some of the cells are shaded, and others are not. Or, if you have multiple panels in a series string, the bypass diodes allow the other panels in a string to continue to contribute energy when one panel is shaded. Unless you're forced to put the panel(s) where there will be shade during the day, the bypass diode does not matter. Commercial panels all include bypass diodes. Blocking diodes are generally NOT included on commercial panels. If you're going to a grid-tied inverter, you probably don't need one. There are stringent regulations on how panels must be grounded, and whichever side of the panel is grounded should not have a blocking diode. NEC regulations call for a continuous ground to earth. For example, if you have negative ground on your system, the blocking diodes, if any, should go on the positive terminal of the panel. By the way, if you're in the US or Canada, do understand that a home-built panel will not be legal to connect to a grid-tied system. And a grid-tied inverter that plugs into the wall will also be illegal. I'm only saying this because I don't want you to get hurt, or your house to burn down. Line power is nothing to be trifled with.
