- Q: How will i construct solar panel?
- For powering a something that works on DC, like a gate opener, Elaine is right, and in some cases only ONE bigger cell is sufficient due to battery storage; however if the appliance is 20v AC, then an inverter is needed also. MOST of Elaine's answer is good, but a few corrections are needed: Plywood - use EXTERIOR grade only, and even then it can warp; chipboard or waferboard is preferable as it does NOT warp, BUT is not available most places in 3/8, /2 nominal, (5/32) is usually the thinnest available, and it is heavier than plywood. DO NOT use particle board. Superglue - NO, it dries too fast to be useful, in most cases. Wires - For a single cell OK, but for larger panels the best wire is tabbing wire, (which is flat,) which is available from all commercial solar cell dealers. Be very careful soldering this to the cells, as unless you buy the expensive flexible cells, they are easily damaged; I suggest also getting flux pens with liquid flux. Diode - Necessary, but needs to be large enough to handle voltage and current. Usually 25v and 5-30 amps,, one per panel. Plexiglas - OK, but NOT as long lasting as glass; best glass is the special solar glass which is designed to pass almost all of the proper light frequencies, but IS expensive, and usually needs to be specially ordered since most glass stores do not stock it. Double panes work well with the outer pane glass and the inner plexiglas, (to protect the cell if glass broken,) IF where might get damage, such as 'ground' mounting. AND Frame kits are available for larger panels, but IF you make your own, a good table router is a great advantage. Inverter - IF used for 20v AC appliances you MUST have an inverter capable of handling the load, and the best ones are modified sine, or true sine, wave types, and even the best are less than 50% efficient. Note that they will last longer if NOT used at more than 2/3 capacity.
- Q: Can solar panels be connected to the grid?
- Yes, solar panels can be connected to the grid.
- Q: Can solar panels store excess energy?
- No, solar panels cannot store excess energy.
- Q: Can solar panels be installed on sports stadiums or arenas?
- Yes, solar panels can be installed on sports stadiums or arenas. Many stadiums and arenas around the world have already installed solar panels to generate clean energy and reduce their carbon footprint. These panels are typically placed on the rooftops or parking lots surrounding the facility, taking advantage of the ample space available. Additionally, some stadiums have even incorporated solar panels into their architectural design, creating visually appealing and functional structures.
- Q: Online stores selling solar photo-voltaic generation kits gives specs indicating the power generation capability of the system. For example, Solar World Grid-Tie Solar Electric System with 245W Panels PV Powered PVP2000 Inverter, .2 to 2.4 kW. This seems to indicate that the system can generate .2 to 2.4 kW. Is that per day? Per month? I'm trying to calculate the return on investment, but can't because I don't know how much power a system such as this will generate in a month.
- As Ed said, that .2 kW is an instantaneous rating in bright sun. The way to do this right is to consult the maps here rredc.nrel /solar/old_data/nsr... to find the number of equivalent sun-hours your location gets per day. Select, Average, Annual, Flat plate tilted south at latitude. A map will come up. For northern California, it shows 5 equivalent sun hours per day, for example. If the system is .2 kW, then .2 x 5 = 6.0 kWh of energy the system will generate per day, on average. That takes into account cloudy days, short winter days, long summer days, everything. The 2.4 kW system would give double that, obviously. But that's an example, based on a specific location. Phoenix would do better, Seattle would do worse.
- Q: Can solar panels be used to power an air conditioning system?
- Yes, solar panels can be used to power an air conditioning system. The electricity generated by the solar panels can be used to run the air conditioning unit directly, reducing reliance on the grid and saving on electricity bills. However, the feasibility and effectiveness of using solar panels for this purpose may depend on factors such as the size of the solar panel system, the energy efficiency of the air conditioning system, and the availability of sunlight in the area.
- Q: Can solar panels be used in areas with high pollution or smog?
- Yes, solar panels can be used in areas with high pollution or smog. While pollution and smog may reduce the efficiency of solar panels to some extent, they can still generate electricity in such areas. However, it's important to regularly clean the panels to maintain optimal performance.
- Q: Are there any government incentives or rebates for installing solar panels?
- Yes, there are several government incentives and rebates available for installing solar panels. These incentives vary by country and even state in some cases. Examples include the federal solar Investment Tax Credit (ITC) in the United States, feed-in tariffs in certain European countries, and grants or rebates offered by local governments. It is advisable to check with local authorities or consult a solar installer to determine the specific incentives available in your area.
- Q: Do solar panels require batteries?
- No, solar panels do not require batteries.
- Q: Can solar panels be installed on a high-rise building?
- Yes, solar panels can be installed on a high-rise building. In fact, high-rise buildings offer great potential for solar panel installations due to their large surface area and access to sunlight. However, it is important to consider factors like structural integrity, shading, and local regulations while designing and installing solar panels on high-rise buildings.
