  • Thin Film Solar Panels.

    I am looking for solar panels to start a small to medium size off grid system and came across these thin film pv for $.98/watt. Does anyone have any experience with these panels. I understand they are for 48volt system, and I haven't started anything yet. Was waiting to see what overall cost would be. Why are these panels so cheap? Are they garbage? I also understand that you need twice the space since they are half as efficient, but are they even worth messing with. I just have heard a lot of negative things about thin film panels, and want to know if what i have heard is true or not. Is the only downside from a mono/poly silicon panel the efficiency. I found them at sunelec.com, which is a company in Miami. If anyone has dealt with this company, a review would be appreciated. Thanks in advance

    Thin film is a well known panel. You are right, they need more surface area for the same watts, and they also generally have a shorter 80% of spec life. Often, a new 200W panel, will put out 250 w for the first year, and they slowly degrade, at a higher rate then Mono/poly panels. The Vendor only sells them, the Mfg carries the warranty. AFIK, Sunelec is a OK vendor.

      The price is too cheap. I do not know which type of glass do they use? Is this double glass thin film module? You need to check with them carefully.

      I know the market price is 1,35US$ from the mft.
