Rather than leaving a generator and the power cord to charge my batteries daily RV, I decided to buy this set and hope that it will meet all my needs for electricity while camping. It is very good. I took the advice of another poster and I bought a more efficient charge controller separately, Morningstar MPPT and it is displayed. The MPPT charge controller increases the efficiency of up to 30% or more. These solar panels can easily keep all four batteries in my trailer loaded and recently averaged less than 10 amps of charge for each hour of the day. I searched everywhere on the web, and Amazon have the best price for this particular set, or something similar. The money saved is enough to upgrade the charge controller more effective. Those who came with some nice extras like a 200W converter, tests tension gauge, many son and 6 hooks per panel.

The panels were delivered to me on the west coast of the East Coast and arrived in good shape, outside the area was damaged, but the box inside was fine.
Tester is disappointed that the battery monitor, modified sine wave inverter, son, brackets and bolts are loose inside the box with one of the panels, looking as they can easily damage the panel of white paper protection.
The cables with lugs attached to the first panel to the regulator has been easy. When I tried to connect the second panel to the first I found the screws too short to allow the heel end of the cable. I had to cut the heels and flat cable before the screws would start. I’m sure it’s a good thing but it is not so sure in this way.
Good point: The second day with one panel being used, I had a reading of 7. 2 amps from a 7th highest possible score as the 14th lasted only a few minutes, I usually avereged more than 6 amps on cool sunny day, except early morning and late evening. When cloudy, I had the power to read everything from one amp to 3 amps.
Bad Point: the 108 rectangular cells, I just had to shadow a couple of them for production is reduced to almost nothing. Do not install panels near a mast, that the least amount of shade to go worthless.
I watched the four-minute video on Amazon, which has shown signs are installed in an area. From the idea that I developed a wobble under TEETER get on the roof with a southern exposure. It rocks on the morning of the East and West fail in the evening between about 48 degrees and a slope of 8 degrees to the south. From what I read elsewhere, it gives me 20% to 40% increase in production during the summer when I need it most.

This kit is two panels high (123W EA) for a total of 246W. Their power curves are ideal for 12V battery (24V or wired in series for 24V system), I reviewed the 123W powerful group two years ago, and found it well done, but gave up and brought strong 130UJF greater efficiency. Note that these are polycrystalline vs. other Sunforce (large) monocrystaline panels shall be paid on 15W in this size.
Sharp 123W coupe version in 2008 due to efficiency improvements (this model is approximately 12 5%) and replaced by a panel 130w in the same form factor in progress 13 1% efficiency. This package will probably disappear when the stock panel end-ND L3EJEA as he was interrupted by Sharp. It is not great, but later you want to add you encounter a technical problem. Your original plates and 123W is your last game is 130 watts, so no “good” game of the series cable facilities if you do not exactly double your capacity for a second string of panels. You will also find that the parallel connection of the new 130W 123W of power will change the point of the combination. You can check to find the latest 130W (sharp p / n ND-130UJF) now, and compare $ / W to just buy the panels.
The UPS is not likely to find much use – its value is close to zero.
charge controller can provide more total watt hours per day if there was a design MPPT, but the price is almost free. If they were re-kit this inverter and controller, but they could hit $ 5/watt low-cost solar point
price [$ 5/watt price level is a guideline that you encounter on the system itself, over 1 kW and is only a rough rule of thumb. Generally, if you do it yourself you will end up around $ 5/watt system - if you hit it with a lot of EC $ 4. 25 / W you deserve a pat on the back. Over $ 5/watt and there may be a better offer waiting for you - but you may need to buy more discs for the price. $ Price 5/watt This surprisingly has not changed for years!]
When you get these signs, you can see individual cells and connections between them can be considered that the 130W and 123W panels are identical in design – that the efficiency of the cell was changed.
If you have purchased two of these kits now parallel versitility in all four 492W 12V system, or does 1:02 series, two parallel systems, 24V 492W, or even a series wired 48V 492W 4×1 panel installation. Specimen charge controllers and inverters on ebay and buy a MPPT revenue
