i need someone to advice me which solar panels to buy.i have looked into few companies and i need some more info before decidingthe companies i checked were Sun tech trina solar Canadian solar and LDK solar.whice company should i pick?? please help.
I did that 25 years in the past and happy I did. they're nonetheless operating high quality with little upkeep. we stay in necessary large apple so we've about an same type of cloud cover you do, and at the same time as that is no longer suitable, you could make it artwork. the nice and comfy button isn't spending plenty so that you've a life like payback time. I designed and outfitted my own, yet i did not layout for top performance; and at the same time as it would not generate all our warm water each and each of the time, it takes the edge off our gas bill. locate someone who has them and note if it paid off for them. don't be the first to get them until eventually you opt for to do slightly engineering. image voltaic voltaic panels could no longer be used to warmth water electrically, that is truly inefficient and could no longer payback. DHW heating is low-tech and all and dissimilar needs warm water. Voltaics receives extra valuable in years yet to go back, and expenditures are dropping so it would not make experience to purchase now.
Selecting the right solar panels is like shopping for a car. Shop around and compare prices. Make sure the frame material will not rust or corrode away after a few years if you are near the ocean. Talk to satisfied customers is always wise. Get the guarantee in writing.
If all things are equal buy local. If you are building for a LEED project then choose a manufacture within 500 miles. Another reason to choose a local panel is that if things go wrong there is a better chance of a satisfactory resolution. A no name knockoff from overseas might prove to be difficult to find a few years down the road. One good place to check is the Go Solar California website. They have proof of performance testing on hundreds of panels.
Are you talking about buying panels, or investing in stock? LDK does not make panels, they make solar grade silicon that goes into panels. I haven't heard bad buzz recently about any brand of panel. Therefore, I would go by price per watt alone. If you type in solar panel price into Google, you're sure to get directed to the major sellers, each of whom will sell many brands of panels. There are a couple other requirements that I would have for a serious system: ) Safety certification such as UL. This will be legally required for a grid-tied system. All panels except the really fly-by-night brands and factory seconds have this. 2) 25-year performance warranty. It's standard now for a manufacturer to guarantee that their panel will still produce 80% of the rated output after 25 years. Older panels may say 20 years. Junk panels will have no such warranty, or something ridiculous like 90 days or year. 3) Crystalline silicon. Monocrystalline or polycrystalline doesn't matter. Every few years, someone claims that they have an amorphous or thin-film technology that's durable. Being conservative, I'm still waiting for such things to be proven. Some crystalline panels have been in service since the 70's, although they are pitifully weak by today's standards. I've heard good things about the Sanyo HIT hybrid panels, but that's only from one person who had them installed.
