1.Today,we will show you some skills about how to choose a good solar panel and some important parameter about solar panel you must reference when you buy the solar panel from the market.Delight future, Do-solar![26th,Nov. 2008]Solar Panel Considerations:
Solar panel are certainly in vogue today and it seems like everyone is building their version of the next great PV (Photovoltaic) module. Prices range from $3 to $20 per watt and the panels come in so many configurations that it hurts to think about all the options. Considerations include:
1.Watts - Maybe the most commonly used measurement of a solar panel, “DC Watts” tells you how much power the panel is capable of generating. Solar panels for home and commercial applications currently range in wattage from 5 - 220 watts and these numbers continue to grow as panels become more efficient.
2.Efficiency (Solar Panel’s ability to convert sun into power) - Some solar panels just put out more juice per square inch than others. They also may operate better in off-perfect conditions. For these reasons, it makes sense to pay attention to the efficiency rating when you go shopping for solar panels.
3.Size - This is important if space is limited or confined to a certain shape. Solar panels take up a lot of space, so pay attention to the dimensions and work out the numbers to see how many square feet of space you will need. (length * width * number of panels)/144 Voltage - Depending on your application, you may need to consider panels that have a voltage better suited to your system design. Common solar panels range from 12 - 60 volts.
4.Warranty - You are making a huge investment so you want to pay attention to how the manufacturer backs up their products. As this industry is really starts to grow, many solar panel makers come and go. I would suggest sticking with a maker that is proven in the industry. We will look at several solar panel makers in just a minute, but you should expect to get a warranty of 20 - 30 years on most quality solar panels. It also pays to read the fine print to see what that warranty covers. Some only cover the complete failure of the panel; not depreciated production due to partial panel defect or failure.
5.Application - There are rigid solar panels encased in glass and frames like we all have seen, but there is also new technology breaking into the market. Solar power producing panels are being designed into all sort of common items ranging from fabric to roof tiles. So if you need a new roof, you may consider using a product that not only keeps you dry, but also generates power.
6.Weight - Usually weight is not a major consideration, but it may come into play if you are adding solar panels to a light weight structure. When in doubt, consult an engineer
