Product Description

     20w mini flexible solar panel
    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:solar panels and batteries?
If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK
Q:Have a 40watt 20volt solar panel, how many watt of inverter do I need?
500 Watt Solar Panel
Q:Why do solar panels burn out?
could be temperature, poor design and U-V damage If they are outdoor lamps like mine it is more likely the rechargeable batterys are bad.
Q:are solar panels sufficient for electric heating?
Are you thinking of installing electric solar panels or thermal solar panels or both? It would be better to install electric solar panels for electric heating. You can run 7 heaters as long as you do the calculations for the number of panels need for the daylight hours, and the required battery bank to supply the required power.
Q:What is the anatomy of a solar panel?
You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
Q:what is the best solar panels to use on my new house(tube or flat)?
I assume you're talking about heating water. Based on what I've seen, the spiral tubes seem to heat the water to a higher temperature than the flat panels, probably because the water has to follow a longer path and has more time to heat. This type of panel will heat the water to a high enough temperature for almost any household application, but you need to be careful about how you set it up. I once saw a pool that had been equipped with that type of heating system, and it produced enough heat to melt one of the PVC pipes. It was a vertical pipe next to the filter, and it had fallen over onto the ground, pinching off the flow of water. This was in Arizona, so it may not get that hot in your area.
Q:What is the principle of solar panels to convert solar energy into electricity?
optical cable communication pump Station power, seawater desalination system, urban road signs, highway signs, etc. Europe and the United States and other advanced countries will be integrated into the photovoltaic power generation system and remote areas of natural village power supply system into the development of the combination of solar cells and building systems have been formed industry Trends
Q:What are the properties of Solar Panels?
American scientists have developed a new coating, which allows the solar cells to cool on its own, without relying on costly cooling and ventilation. Coating increases the output power and prolong the life of solar batteries .
Q:Solar Panel, what is the catch ?
The catch is you pay a monthly electric bill to the company that installed it. There are a couple ways to pay for solar power. One way is to pay the full cost of installing it then get all the power it makes at no cost. The other way is they install it for free and they become like a second power company. You pay them for the solar power and still pay your electric utility for any power from their generator that you use. The idea (usually a promise) is that the monthly rate will be lower than the power company charges. I would prefer to pay the full cost of the installation and own the power it makes from then on. But you need to have enough cash, or the ability to borrow enough, to pay that way.
Q:would the planet cool if covered in solar panels?
The opposite - they heat the Earth up. The ground underneath might be brown or green or sand. The solar panels are Black. They absorb more radiant energy. Solar electricity is energy and somewhere down the wire will produce heat. Solar's saving grace is that it has the same heating effect year after year. But greenhouse gasses have a cumulative effect. The excess gasses produced in year one are added to the gasses in year two, etc. For instance say the heating of soalr cells is 5 times (5s) that of greenhouse gasses (g). Year - Total Heating - 5s + g 2 - 5s + 2g 3 - 5s + 3g 4 - 5s + 4g 5 - 5s + 5g 6 - 5s + 6g 7 - 5s + 7g 8 - 5s + 8g 9 - 5s + 9g 0 - 5s + 0g etc... In 50 years you have 50 - 5s + 50g
