- Q: I have a cabin that is way out in the middle of no where, it would cost 000's of dollars to get power to it. If I have a 8,000 BTU air conditioner that runs on 25 volts and 5 amps (or 875 watts)How many solar panels will I need to run this during the day, plus charge the batteries to run it all night? How many batteries would I need
- You are probably going to need about 60 panles and 60 batteries....you will also need a very good power inverter. Also consider the power it takes to invert 2 volt DC battery power in to 20 volts AC power required for an air conditioner. You might consider also trying to find a 2 or a 24 volt unit cooler. You would be better off buying a generator. Solar panels and batteries are not going to run an air conditioner for long if at all.....it might be cheaper to have the power company run the power.
- Q: I am looking for an average sized solar panel (Just Panel), not 2 big n not 2 small. Any idea where i can find in abudhabigt;??
- Abu Dhabi Solar plant Shams will be completed by the end of this year and will be ready to provide Abu Dhabi with power at commercial prices. Construction began during [the third quarter] of 200. The project's cost is $600 million (Dh2.2 billion) and with its completion, it will be the largest solar project in the world, Yousuf Al Ali, General Manager of Shams Power Company told Gulf News. Once completed, Shams will be one of the largest concentrated solar power [CSP] plants in the world, extending over an area of 2.5 square kilometres with a capacity of approximately 00MW and a solar field consisting of 768 parabolic trough collectors, Al Ali said. He added: Shams is a joint venture between Masdar (60 per cent), Total (20 per cent) and Abengoa (20 per cent).

- Q: 260 watt solar panels on an rv?
- It depends on the power you need. There should be a controller between the battery and the solar pv panels.
- Q: all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?
- The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
- Q: Was looking at 0w solar panel kit. Does this mean, all I can use is something like a 0W CFL light bulb and nothing else?
- Graham is on the right track. However, you need to factor in a 80% DC to AC conversion loss. But yes a 0W CFL is about the size of it... Harbor Freight sells a system consisting of panels, battery, inverter, and TWO CFL's for $250. (You can power 2 CFL's off the grid for a very long time for $250)
- Q: Can solar panels be installed on a historic building?
- Yes, solar panels can be installed on a historic building. However, it is important to carefully consider the impact on the building's aesthetics and historical integrity. Specialized techniques and materials may be required to ensure that the installation is done in a way that preserves the building's unique architectural features. Additionally, it may be necessary to obtain permission or meet certain requirements from local historic preservation authorities before proceeding with the installation.
- 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: Can solar panels be used in areas with high levels of saltwater exposure?
- Yes, solar panels can be used in areas with high levels of saltwater exposure. However, it is important to take certain precautions to prevent corrosion and maximize their performance. This can be achieved by using materials that are resistant to saltwater corrosion, such as stainless steel or aluminum frames, and encapsulating the solar cells with durable and protective coatings. Regular maintenance and cleaning can also help ensure the longevity and efficiency of solar panels in such environments.
- 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.
- Ideally, you should not be trying to run individual appliances off of a solar panel. What you should be doing is selling the power harvested from these panels back to the power company as a savings from your power bill. Here in southern California I have heard of people actually receiving monthly checks from the power companies.
