Product Description
sunpower flexible solar panel 20w for sale
Flexible solar panel are designed to provide a powerful charging solution for batteries and conform to almost any surface. Unlike other 'flexible' products, these use high-efficiency monocrystalline cells that produce more power per square foot than any other flexible panel on the market.
An impermeable lamination coats the entire module, allowing it to contour and flex against curved areas, eliminating any need for custom mounts.
The panel can be affixed by adhesive or screw mounting options and grommets are an added bonus for ease-of-installation. The thin, lightweight module can also be sewn into canvas, making it a truly versatile solar m odule.
The Solar Flex panels are aerodynamic and DURABLE - a virtually unbreakable solar battery charger for RVs, boats and long-haul trucks.

- Q:
- Yes, solar panels can be used in areas with high levels of snow or ice. However, their efficiency may be reduced during winter months due to reduced sunlight exposure and accumulation of snow or ice on the panels. To mitigate this, solar panels can be installed at an angle to allow snow to slide off, or they can be equipped with heating systems to melt the snow or ice. Additionally, regular maintenance and cleaning may be required to ensure optimal performance in snowy or icy conditions.
- Q:
- Solar panels can have a significant impact on the appearance of a home or building. They are typically installed on the roof, and their sleek and modern design can often enhance the aesthetic appeal of a property. However, some people may find the presence of solar panels less visually appealing, especially if they are not installed in a well-integrated or discreet manner. Ultimately, the effect on appearance depends on personal preferences and the design choices made during installation.
- Q:I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
- There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
- Q:Say if i had a 2KW system is thtat just one big solar panel or does the whole system have little solarpanels together.?
- A two KW system would be made up of a number of solar panels. Panels used in residential and commercial systems usually run in the range 50 watts to about 200 watts. There is a HUGE amount of information available on the internet about solar panels and all the components of solar electric systems. All you have to do is search on the internet under solar panel. It's very safe and easy. So just do it.
- Q:I am completely ignorant on this subject. I was just wondering out of curiosity of how many solar panels and equipment that it would take to run a central ac for a 2500 sq ft home and a pump for a medium sized pool. I'm talking running ac for like 8 hours a day to keep around 65-70 degrees and running the pump 24/7. Just looking for a general ballpark answer.
- Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
- Q:I have a 2V .5W solar panel and I want to get a battery that can be charged by the solar panel that can then be used to power a 2V .5W fan. Ideally I want all the components to be connected and able to run without interaction. I have very little knowledge in regards to this field which is why I have come to yahoo answers. Any help would be greatly appreciated.

- Q:
- Yes, solar panels can be installed on boats or RVs. In fact, solar panels are a popular choice for both boats and RVs as they provide a sustainable and reliable source of electricity while on the move.
- Q:
- Yes, solar panels can be used to charge electric vehicles. By installing solar panels on rooftops or in parking lots, the energy generated from the sun can be used to charge the batteries of electric vehicles, providing a clean and sustainable source of power. This helps reduce reliance on fossil fuels and promotes renewable energy use in transportation.
- Q:
- Solar panels can have a significant impact on a property's energy management system. By converting sunlight into electricity, solar panels can provide a clean and renewable source of power, reducing the property's dependence on traditional energy sources. This can lead to significant cost savings on electricity bills and also help to reduce the property's carbon footprint. Additionally, solar panels can integrate with the property's energy management system, allowing for better monitoring and control of energy usage, optimizing the overall efficiency of the system.
- Q:
- Yes, solar panels can be effectively used in combination with other renewable energy sources such as wind turbines, hydroelectric power, or geothermal energy. This combination, known as hybrid renewable energy systems, allows for increased reliability, better utilization of resources, and a more stable power supply.
