CNBM 270W Mono Crystalline Solar PV Modules




provides a 13 year limited warranty (“Warranty”) against defects in materials and workmanship for its Uninterruptible power supply, Power inverter/chargers, Solar charge controllers, Battery Products (“Product”).

The term of this Warranty begins on the Product(s) initial purchase date, or the date of receipt of the Product(s) by the end user, whichever is later. This must be indicated on the invoice, bill of sale, and/or warranty registration card submitted to MUST-Solar. This Warranty applies to the original MUST-Solar Product purchaser, and is transferable only if the Product remains installed in the original use location.



1.    How do I decide which system is right for me ?

For protection from long outages, include a generator or solar panels in your Must solar system. Shorter outages can be handled by a battery-only system.

2.    Where my system will be installed ?

Must solar systems are usually wall-mounted near a home's main electrical (circuit breaker) panel.

3. How do I install my system ?

A must solar backup inverter is connected to a home electric system , we will supply detailed installation manual and videos for our customers .

Q:Charge Laptop with Solar Panel?
humm..... .need HUGE solar panel (alot) 2. wires 3. aligato clips . put the panels on the roof 2. use the aligator clip to clip the wire from the panel to the bars of the pluger of the comp. charger 3.tada mark me best:)
Q:Can someone please explain to me the basics of solar panels and power storage/usage?
Unlike what most people seem to think, solar panels are not advanced enough to power day to day objects that we use, with the sun that we see in a day. You would need mass amounts of panels and equipment. IF there is a smaller solutions (which I doubt would do what you're asking yet) it would cost thousands of dollars. Panels are not there yet, and the ones that are, are still in development or being guarded from release to the public. The most you'll get out of a few hundred bucks and panels is a lit garden for a few hours at night. Go buy rechargeable batteries.
Q:Need help with a solar panel?
In order: .  Just about any wire will do.  You can handle 50 mA over just about anything, even 28 gauge telephone wire.  Your biggest problems are probably going to be mechanical stress (you want stranded wire instead of solid, to avoid breakage) and dealing with the size of larger wires. 8 gauge speaker wire may be a good optimum. 2.  You need a diode.  If you're charging NiMH or NiCd cells you're going to have about .25 volts/cell; you can charge up to 3 of them in series with a 4.8 volt panel.  The solar panel is a bunch of diodes itself, but they're leaky in the reverse direction; the diode prevents the batteries from discharging themselves back through the panel.  You want a Schottky-barrier diode, because the forward voltage drop is about 0.2 volts instead of 0.7 volts for a regular silicon rectifier.  This gives you maximum current output from your panel.
Q:Solar Battery System?
A solar panel is usually 36 cells and intended to charge a 2V lead acid battery. The battery in laptops may be somewhere between 5 and 20V. The panel might charge a laptop when it is cold, but they heat up in the sun and then it would no longer charge. Typical lap top power supplies are 3 to 4 amps. You need 2 panels in series to get enough voltage to charge the battery directly, but this is wasteful. If you want to charge at the same rate as a lap top power supply you need large panels to provide 5 amps. The 5 Amp panel will only give 5A when pointed directly at the full sun. There may be between 2 and 5 hours a day equivalent full sun depending where you are, time of year. If you want more than that, you need larger panels, or more than one in parallel for a 2V system. It makes sense to charge a 2V battery with the solar panel, and use that to operate the lap top with a car type power supply for a laptop, which runs from a 2V battery (see link below for an example). Get the biggest panel you can afford, and the battery should be larger if you want to run the lap top when the sun isn't shining. Perhaps a 20AH battery is a minimum size. All this costs more than a lap top.
Q:solar panel battery size?
A lot will depend on the Sun light available at location where you plan to install this. The electricity the panel generates is at times 0-20% only of what it is rated. Start small and do some initial readings on the generation and then scale up.
Q:How much does a race car that uses solar panel cost?
Q:How may solar panels/wind turbines may be made affordable?
economies of scale or mass production is the answer to just about any item being made it cars or computers or solar panels. Now, how to get there is the question..... market forces? as more people want a 'greener product demand goes up quantity produced goes up unit price goes down....but that takes awhile.... government help ? subsidies...the US gov takes some of your tax money and makes it available as rebate to people putting panels/wind systems in their homes, and establishes policies to companies to take less taxes if they build wind/solar.... government orders: You MUST put in a solar panel ( or we'll send the Green Police to bust you)
Q:in a solar panel, where do the protons go?
silicon based photovoltaic cells used some boron as dopant. i dont understand if that helps supress proton pastime, the way they be conscious boron on supressing run away nuclear reaction.... im clueless as you
Q:Powering my house with solar panels?
Homes vary tremendously in their usage. It will be a factor of 0: between a conservative house, and a heavy use one. To get the answer for your own house, check the electric bills. Also, the answer for the size of solar electric system varies with the location of the house. A Minnesota residence may get only 2/3 or /2 of what an ideal California house gets, even though both are sunny. As a data point, our California house has no air conditioning, no electric heat, no pool, and no big screen TV. We use maybe 5 - 8 kWh a day on average (more in winter, less in summer). We have a 3 kW solar array on the roof, and it roughly keeps up with our usage.
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.
