The Equipment of Solar Polycrystalline Series (40W-50W)
The Usage of Solar Polycrystalline Series (40W-50W)
- Q: Are there any disadvantages to using solar panels?
- Yes, there are a few disadvantages to using solar panels. Firstly, the initial installation cost of solar panels can be quite high, which may deter some people from adopting this technology. Additionally, solar panels require a significant amount of space for installation, making them impractical for individuals with limited rooftop or land availability. Furthermore, solar panels are dependent on sunlight, so their efficiency can be affected by factors such as weather conditions and geographical location. Finally, the production process of solar panels involves the use of certain chemicals and materials that can have negative environmental impacts if not properly managed.
- Q: Where can I find good instructions to build a cheap solar panel on my own?
- Building solar panels is not really a do it yourself kind of job. They are made in high tech factorys with specialized equipment and experianced engineers. It would probably be cheaper and easier to just buy some panels rather than try to make your own.
- Q: Solar panels are costly.Do you know any inexpensive way?So that i can make one of my own.
- Solar things are always costly... You can use concave mirrors and concentrate the heat and heat what and then steam ll be formed and then steam directed to turbines, there you go generating electricity with out solar panels...
- Q: Can solar panels be installed on flat surfaces?
- Yes, solar panels can be installed on flat surfaces. However, for optimal performance, it is recommended to tilt the panels at an angle that allows them to capture maximum sunlight.
- Q: Do solar panels require regular maintenance?
- Yes, solar panels do require regular maintenance. This includes cleaning the panels to remove dust and debris, checking for any damage or defects, and ensuring proper functioning of the system. Regular maintenance helps to maximize the efficiency and lifespan of solar panels.
- Q: i was told that by making a solar panel they cause more pollution than they will end up getting rid of. Is that true?
- It depends on what type of pollution you are talking about. Some of the newer cells that don't use silicone are made with dangerous chemicals that are just dumped into the local water supply when made in China or other places with no real environmental controls. No matter how much carbon free energy the cells produce they will never clean up the mess people made when building them.
- Q: Are solar panels safe for the environment?
- Yes, solar panels are safe for the environment. They produce clean and renewable energy by converting sunlight into electricity without emitting harmful greenhouse gases or pollutants. Additionally, the manufacturing process of solar panels has become more sustainable over time, reducing their environmental impact.
- Q: If you buy everything you need for a grid-tied solar set up, can you install it yourself or is it required that a professional installs it?
- Solar panels have to be installed by a professional in order to get the government rebates. Also the systems must meet state and local electrical codes. Most modern inverters will not turn on unless there is live power from the MAINS, so a ultility company is NOT required for any installation anywhere. There are plenty of electrical contractors and speciality solar contractors out there to help you to make sure that the system is properly designed with the correct components, properly installed, and legally certified. Also many states require a permit that may have a large fee before any installation and may not allow the homeowner, especially for city homes, so it is best to check first. You might be able to get away with it if you live in the country, but consider the safety as well. See if you can work with your contractor to get the materials that you both agree upon as well. They can help guide you based upon their experience. Also shop around for pricing as the panels are now going below $ per watt !
- Q: i used 734 killowatts of power last month, any idea on how many solar panels i would need. What im looking for is to somehow hook up my central air to solar panels.
- Good answer above me. One other tip, look at your full year's usage. Last month, if it was cold, you probably didn't have your air conditioner on. Our house uses 500-600 kWh a month average, but we have no air conditioner. To generate all of this requires a 3 kW array in our part of California. That's only to give you an idea of what it takes - what you need will be based on how much sun your area gets, and what percentage of power you want to get from the array. If you pay tiered electric rates, it may make sense to displace only part of your electricity with solar. Or it may not make financial sense at all, if you have cheap electricity where you live. To get the best assessment of what kind of system would be appropriate, try to get one or two no-obligation quotes from local companies. You can always turn down the bids, but at least you will have learned what's involved and the approximate cost. If you want to see what we did with our house, please contact me through the email in my profile.
- Q: Home depot has solar panels but they are so expensive? were is the best place to get them?
- You okorder (or any other website you can find in a search engine) to get a list in your area. Good luck!
