will i need to take the battery out at the end of the day to recharge the battery?
They put out such a small charge I don't think it ever will charge a dead battery, solar chargers are more like battery maintainers. It will take some time to charge a low battery.
A quick overview of my new solar system. The heart of the system is the 20 watt solar panel, hooked up to an 8 amp charge controller. I use the ...
I am using the battery and solar panel on a deer feeder. The solar panel just maintains the charge. I didn't know if the battery would deplete faster than the smaller volt solar panel could supply a charge.
hi yes it will take some time. lets talk about electricity voltage is like the pressure from a hose. amperage is like the amount of water flowing from the hose. ohms are the total flow available. a rechargeable battery uses a chemical change to...

can you run those in series to charge say a 36 volt system
Yes you could, but you will still get the same charging capacity (current) as you would with only 1 at 12V
can 2 9-volt in parallel be recharged from a 12 volt solar panel, or would they only charge up to 6-volts each?
I know they can not be charge in series, the 12-volt is to much for the 9-volt, so they have to be in parallel. but will a...
It works well to charge any voltage "below" the voltage of the photo cell. It is best to either build of buy a charge controller for the voltage you want to charge - that will keep you from overcharging your 9V batteries. (The other answer

Solar-powered sprayer that solves many problems
One need not be a genius to develop any commonly used devices. Take the case of the humble yet important knapsack manual sprayer (hung on the shoulders).
Though many models are available on the shelves, priced at different rates, most of them last for only a few years.
“Regularly filling them with water, pesticides and fuel (in case of fuel operated ones) makes it difficult to lift and hang them on the shoulder. After an hour of spraying, the weight of the machine creates a backache and shoulder pain for farmers,” says Mr. David Raja Beleau, Assistant Director of Horticulture Kadayam, Tamil Nadu, who developed a solar powered battery operated sprayer for farmers.

Sunforce 39626 160-Watt High-Efficiency Polycrystalline Solar ...
The Sunforce 39626 160-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 160 Watts of clean, free power in all weather conditions. The Sunforce 39626 160-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. The Sunforce 39626 160-Watt High-Efficiency Polycrystalline Solar Power Kit has everything you need to start generating power. It includes two (2) Sharp 80-Watt polycrystalline solar panels with durable rustproof aluminum frames, a 200-Watt power inverter, a 30-Amp Digital Solar Charge Controller, a voltage tester, and a wiring kit with mounting brackets and accessories for easy installation. 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 two Sharp polycrystalline solar panels that have a maximum power output of 80-Watts/4.67-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 200-Watt power inverter allows you to use traditional 110-Volt appliances with this system. The included 30-Amp Digital Solar Charge Controller must be installed to prevent any connected batteries from overcharging. It can handle up to 500-Watts of total power from any number of solar panels connected in parallel. The charge controller will also keep any connected batteries from discharging at night. High-efficiency polycrystalline solar cells from Sharp provide advanced power output Weatherproof solar cells feature durable aluminum frames with tempered glass coverings Includes two 80-Watt polycrystalline solar panels, a 200-Watt power inverter, a 30-Amp digital charge controller, a voltage tester, and a wiring kit with mounting accessories 25-year solar panel warranty Kit is easy to install and virtually maintenance-free I ordered this but although the two panels and mouting kit were present the packing was inadequate and well battered - being only very thin fibreboard for something weighing 60 pounds and no proper bubblewrap of panels. A corner of the packing had broken open. It would seem the charge controller and and inverter are missing. The panels seem OK but I would advise purchasers to inquire as to packing. Maybe Amazon need to charge 20 dollars more for packing. Howevever good value if enventually I get everything! I am about to be 50 and all my life I have been interested in technical things. Not sure if the special interest for the wind, and how to use the wind, started when I as a 5 year old boy and got my first sail dinghy.
