Sunforce 39126 246-Watt High-Efficiency Polycrystalline Solar Power
This kit is two great sharp panels (123W ea) for 246W total. Their electric power curves are excellent for 12V battery charging (or 24V if wired in series for 24V devices) I evaluated the sharp 123W panel 2 years ago and uncovered it to become nicely made, but then sharp scrapped it and introduced the 130UJF with greater performance. Note these are polycrystaline vs. other sunforce (bigger area) monocrystaline panels which only put out about 15W in this size.

Sharp discontinued the 123W version in 2008 because of efficiency improvements (this model is about 12.5%) and replaced it that has a 130W panel inside the exact same form factor running 13.1% efficiency. This package deal will most likely go away when stocks of the ND-L3EJEA panel run out since it has been discontinued by Sharp. That’s no big deal, but later if you would like to add to it you discover an engineering trouble. Your original panels are 123W and your newest match is 130W, hence no “good” match for series wired installations unless you want to exactly double your capacity with a second string of panels. You can also discover that paralleling the new 130W with your 123W will alter the energy point from the combination. You may well check close to for the newer 130W (sharp p/n ND-130UJF) now and compare $/w to just buy the panels.
The inverter most likely will not discover alot of use – it’s value is around zero.
The demand controller could get you more total watt hours per day if it had been a MPPT design, but at the value it is pretty much cost-free. If they would re-kit this without the inverter and controller they could beat the $5/watt “low price solar” pricepoint
The $5/watt pricepoint can be a guideline you bump into laying out DIY methods under 1KW and is only an approximate rule of thumb. In general in the event you do it yourself you may end up around $5/watt to get a system – when you beat that by alot e.g. $4.25/W you deserve a pat around the back. More than $5/watt and there may possibly be greater deals waiting for you – but you may possibly have to buy additional panels to obtain the pricing. This $5/watt pricepoint surprisingly has not moved for years!
When you take delivery of these panels you can see the person cells along with the wiring between them you may see that the 130W and 123W panels are identical in layout – just the cell efficiency changed.
If you bought 2 of these kits now you would have the versitility to parallel all four for any 492W 12V process, or make a a couple of series, 2 parallel 492W 24V system, or even a 4×1 panel series wired 48V 492W setup. Sell the inverters and cost controllers on ebay and buy a MPPT technique with all the revenue!

Sunforce kits are quick to set up and operate.
Convenient Energy That Helps You Save Cash and Shield the Atmosphere
The Sunforce 39126 246-Watt High-Efficiency Polycrystalline Photo voltaic Electric power Kit lets you harness the electrical power on the sun, probably the most powerful and plentiful source of power readily available to us. This inexhaustible supply of electric power is freely obtainable wherever the sun shines, and gives users the freedom to electrical power their homes, RVs, boats, electric batteries, and electronic equipment far from civilization or proper in town. Pv electric power can assist cut your energy bills by reducing your dependence within the principal electrical grid, and may also supply back-up strength through outages. Unlike nuclear and fossil fuels, solar energy techniques are clean and pollution-free, and they require extremely little maintenance to operate.
Sunforce Solar panel systems are efficient in areas of both substantial and lower
sun exposure, generating them excellent for use inside the United States.

Every little thing You have to Strength Up
The Sunforce 39126 246-Watt High-Efficiency Polycrystalline Photo voltaic Electric power Kit has everything you have to start out generating electric power. It includes two (2) Sharp 123-Watt polycrystalline solar power systems with durable rustproof aluminum frames, a 200-Watt energy inverter, a 30-Amp Digital Pv Charge Controller, a voltage tester, plus a wiring system with mounting brackets and accessories for effortless installation.
With all the integrated 30-Amp Digital Pv Fee Controller set up, there’s no danger of reverse present sapping your battery strength at night. This cost controller may also manage up to 500-Watts of photo voltaic electrical power, producing it ideal for future expansion and use with additional solar energy panels.
About Polycrystalline Solar Strength
Polycrystalline silicon is a material consisting of thin wafers that are cut from a silicon crystal which has grown in numerous directions. This advanced surface texturing method delivers polycrystalline solar power systems that has a higher power output than amorphous panels with the same dimensions, and makes them additional price and space-effective. These individual wafers are assembled into panels that are covered by durable, weatherproof tempered glass. Thanks to their productivity and durability, these solar power systems call for virtually no maintenance once set up. This kit consists of two Sharp polycrystalline solar power panels that possess a maximum electrical power output of 123-Watts/7.16-Amps every.
Solar panel systems convert sunlight into an electric current; they don’t in fact store energy. Sunforce Photo voltaic Strength Kits are primarily applied to recharge all kinds of 12-Volt power packs, including lead-acid automotive electric batteries, deep-cycle (traction form) power packs, gel-cell power packs, and heavy-duty (stationary form) power packs. When utilizing these solar energy panels to run appliances on a normal basis, the use of deep-cycle marine electric batteries is suggested. This kind of battery is created to withstand the frequent cost and discharge cycles associated with pv panel use. Note: This system doesn’t consist of a 12-Volt battery.
The included 200-Watt electric power inverter makes it possible for you to use traditional 110-Volt appliances with this method. The integrated 30-Amp Digital Demand Controller ought to be set up to prevent any connected power packs from overcharging. It can handle approximately 500-Watts of total strength from any number of solar power systems connected in parallel. The demand controller will also maintain any connected electric batteries from discharging at night. Examine this site here too for more answers Sunforce 39126
Sunforce 39126 246-Watt High-Efficiency Polycrystalline Solar Power
Instead of pulling out a generator and electric cord for daily charging of my RV electric batteries I decided to purchase this set and hoped it would supply all my electrical requirements while camping. It does, extremely properly. I took the advice of one more poster and purchased a much more effective cost controller separately, the Morningstar MPPT and it’s display panel. The MPPT controller increases the charging overall performance by up to 30% or additional. These solar energy panels now very easily keep all 4 of my trailer power packs charged and recently averaged at least 10 amps of impose for every daylight hour. I searched all over the web and Amazon had the very best value on this specific set, or anything like it. The income saved is enough to upgrade the controller for more efficient charging. The set came with nice extras like a 200w inverter, voltage test gauge, plenty of wire and 6 mounting brackets per panel.
