Product Description
Amazon.com Product Description
The Sunforce 39305 650-Watt High-Efficiency Polycrystalline Solar Power Kit will give you several more reasons to love the sun. It provides the power you need, while helping you save money and protect the environment. This kit is ideal for cabins, recreational vehicles, remote power, back-up power, and 12-volt battery charging. It comes with everything you need to start producing up to 650 Watts of clean, free power in all weather conditions.
Convenient Power That Helps You Save Money and Protect the Environment
The Sunforce 39305 650-Watt High-Efficiency Polycrystalline Solar Power Kit lets you harness the power of the sun, the most powerful and plentiful source of energy available to us. This inexhaustible supply of power is freely available wherever the sun shines, and gives users the freedom to power their homes, RVs, boats, batteries, and electronic equipment far from civilization or right in town. Solar power can help cut your energy bills by reducing your dependence on the main electrical grid, and can also provide back-up power during outages. Unlike nuclear and fossil fuels, solar power systems are clean and pollution-free, and they require very little maintenance to operate.
Everything You Need to Power Up
The Sunforce 39305 650-Watt High-Efficiency Polycrystalline Solar Power Kit has everything you need to start generating power. It includes five (5) Sharp 130-Watt polycrystalline solar panels with durable rustproof aluminum frames, a 50-Amp Pro-Series Solar Charge Controller, a voltage tester, and mounting brackets with accessories for easy installation. Note: Wiring is not included with this kit.
With the included 50-Amp Pro-Series Solar Charge Controller installed, there is no danger of reverse current sapping your battery strength at night. It can handle up to 750-Watts of solar power, and its auto-switching technology is designed for both 12 and 24-volt systems. The Pro-Series Charge Controller is ideal for future expansion and use with additional solar panels.
About Polycrystalline Solar Power
Polycrystalline silicon is a material consisting of thin wafers that are cut from a silicon crystal which has grown in several directions. This advanced surface texturing process provides polycrystalline solar panels with a higher power output than amorphous panels of the same dimensions, and makes them more cost and space-effective. These individual wafers are assembled into panels that are covered by durable, weatherproof tempered glass. Thanks to their efficiency and durability, these solar panels require virtually no maintenance once installed. This kit includes five Sharp polycrystalline solar panels that have a maximum power output of 130-Watts/7.6-Amps each.
Solar panels convert sunlight into an electric current; they do not actually store power. Sunforce Solar Power Kits are primarily used to recharge all types of 12-Volt batteries, including lead-acid automotive batteries, deep-cycle (traction type) batteries, gel-cell batteries, and heavy-duty (stationary type) batteries. When using these solar panels to run appliances on a regular basis, the use of deep-cycle marine batteries is recommended. This type of battery is designed to withstand the frequent charge and discharge cycles associated with solar panel use. This kit does not include a 12-Volt battery.
The included 50-Amp Pro-Series Charge Controller must be installed to prevent any connected batteries from overcharging. It can handle up to 750-Watts of total power from any number of solar panels. The charge controller will also keep any connected batteries from discharging at night.

Sunforce 39305 650-Watt High-Efficiency Polycrystalline Solar Power Kit
This appears to be a good product, but I have issues with the technical descriptions: I'd like to see the Product description edited. Although this is billed as a 650 watt kit and is shown with 5 panels, the Product description at the bottom states there are only 3 panels (at 130 Watts each). Additionally, the top-section general description states a 50 amp controller, the bottom section indicates only a 30 amp controller. For my following comments, I have used basic electricity formula of Power(P) (in Watts) = Current(I) (in Amps) times Voltage(E) (in Volts) or P=IE The 50 Amp controller is described as being able to handle 750 watts and allows expansion of the system. But since 5 panels at 130 watts already equals 650 watts (54 Amps at 12 Volts), another 130 Watt panel would be 780 Watts (65 Amps at 12 Volts, somewhat above the rated capacity either in Watts or Amps, whichever you choose to use for the description. My final comment and question is that this system is described as being ideal for 12 Volt charging, but that it automatically switches for 12 or 24 volts. So is the output of the solar panels nominally 24 Volt, with the controller determining final output to the battery? My guess is that it's only a 12 Volt output (650W/12V = 54.17A), so what is the purpose of stating it's auto-switching for 24 Volt? Clarification on all these issues will help customers make appropriate choices.

Great service from Sunforce,

Amazon Verified Purchase(What's this?)
This review is from: Sunforce 39305 650-Watt High-Efficiency Polycrystalline Solar Power Kit (Automotive)
I mounted 6 of these panels on a Zomeworks Universal Track Rack UTRF-064 passive solar tracking system in California. Zomeworks was able to match theese Sunforce panels to their rail mounting holes.
Sunforce customer service was excellent. There were some kit pieces lost in shipping from the Amazon warehouse and Sunforce was able to promptly send everything I needed Fedex. Hope to upload some photos soon once it stops raining.
