- Q: can anyone help me? i was thinking of installing solar panels to cut bills but would it be a waste considering its gonna need a circulating pump running almost 24/7 (which will use electricity) and even still will only provide me with quot;warmwater? also would it be possible to install the solar panels for the sole purpose of providing sufficient power to run electric heaters instead of using gas/oil? this way allowing me to have a warm house without the expensive bills. brobably talking about running 7 heaters/electric radiators.
- A thermal solar panel to feed your water heater is the most efficient. But you need a classic heater system too when there is no or little sun. Solar panels to heat a home is not at all recommended. First of all, you get less day light and less sun in winter, so you won't get much electricity. They work best in summer, but electric panels have poor yields and are a very long term investment. You will need to wait years before saving money. Natural gas, a well isolated home, and a good old sweater is the best way to cut bills.
- Q: For a computer technology project we are using solar panels and trying to see different methods that will increase the output of solar power from these panels. For now, we have got polymer stickers and mirrors. Are there any more methods, or information that increase the solar power? Please and thank you :)
- I agree with the other answers; . Different angles to attract more light. 2. Cooling the panels. Just make sure you have a control set up. As for the cooling I'd say if the aim was overall energy efficiency then this method would not work unless you could devise a cooling method that didn't use any electricity.
- Q: I don't know anything about where to buy solar panels. I just want to save on the electric bills.
- First and foremost, you are talking about photovoltaic panels. These harness solar energy and convert it to electricity. The downside to these is that they are expensive, although you will see a huge return on your electric bill in usually 5-7 years. The photovoltaic panels produce DC electricity, so if you want to power your home appliances you will need an inverter that takes DC electricity and converts it to AC (since almost all home appliances run off of AC). You will also need a battery and an optional but very useful charge controller. The battery stores electricity that is generated from the sun to be used on cloudy days. The charge controller is the brains of the operation and deciphers how much electricity should go to the appliance(s) or the battery.
- Q: How does the snow cover get removed from the panels?
- Just okorder /... As an aside the efficiency of the panels will also be maintained if the panels are cleaned of dust and debris. The maintenance of removing snow and dust is one argument for having the panels on a rack on the ground. Solar Thermal panels are intended to capture the sun's heat. Two types that make hot water are flat panels and vacuum tube collectors. The vacuum tube collectors work better in colder and cloudy areas but their efficiency prevents heat loss that might melt snow. Most of a light snow will fall between them but you are back to maintenance with a heavier snow. Flat panels are less efficient and will melt a light snow off of the panels for a heavier snow you will need the roof rake. The last type of solar panel are solar air panels. These are most often mounted on the side of a house rather than the roof as they are intended to provide hot air to the living spaces. They are essentially like little greenhouses. Unless the snow is building up against the side of the house these should be free from a snow problem.
- Q: How Much energy does Solar Panel Produce,and How long can Solar Panels go without maintenance.
- The available energy is a function of several factors including insolation (sunpower) mounting angle, gathering area, type of cell and conversion efficiency.
- Q: Can solar panels be installed on a shopping mall or retail complex?
- Yes, solar panels can be installed on a shopping mall or retail complex. In fact, many commercial buildings have already embraced solar energy as a way to offset their electricity consumption and reduce their carbon footprint. By installing solar panels on rooftops or parking structures, shopping malls and retail complexes can generate clean and renewable energy, leading to cost savings and environmental benefits.
- Q: Can solar panels be installed on research facilities or laboratories?
- Yes, solar panels can be installed on research facilities or laboratories. In fact, many research facilities and laboratories have started to adopt solar energy to reduce their carbon footprint and dependence on traditional energy sources. Solar panels can be installed on rooftops or open spaces adjacent to the facility, providing clean and sustainable energy to power various equipment and operations. Additionally, the installation of solar panels on research facilities can serve as a demonstration of renewable energy technologies and encourage further adoption within the scientific community.
- Q: Can solar panels generate electricity during a blackout?
- No, solar panels cannot generate electricity during a blackout because they are connected to the grid and rely on it to deliver power.
- Q: Can solar panels be used for powering a data center?
- Yes, solar panels can be used to power a data center. Solar energy can be harnessed and converted into electricity, which can then be used to power the various components of a data center, including servers, cooling systems, and networking equipment. By utilizing solar panels, data centers can reduce their reliance on traditional grid power and lower their carbon footprint. Additionally, advancements in solar technology have made it more efficient and cost-effective, making it a viable option for powering data centers.
- Q: Where can I buy solar panels other than online in Charlotte, NC?
- If okorder / They have a network of installers they work with around the country so they should be able connect you with someone locally. If you visit their site they'll provide you with a free solar quote, a break-even analysis, estimated IRR, cash flow analysis, annual savings, and all the incentives you are eligible to receive. Basically, they'll provide you with all the info you need to make a smart decision (if you're looking into a residential scale project of course).
