12 Volt Solar Cells

I`m working on a solar project, need to know how many cells would it take to light a 4 watt bulb? I put some cells in series to get my 13-15 volts, only problem is when I put them in parallel I can`t get the needed volts or current needed to light...

You need to put in series to get voltage and then the same amount in parallel until you get the current needed.

Solar cell that converts solar energy into electrical energy ? What are the cost of 6 volt and 12 volt solar cell ?

For hobby applications you can try the following sites for technical information and then see if they have distributors in your area:

From where i can purchase the solar cells? & i want to charge 4batteries of 12 volt batteries for my collage project i have limited fund please answer me as early as possible....

Well the speed with which you want to charge those batteries is a direct relationship to what size solar panels you need. Lot's will do the trick. However, the charge controller you use dictates the voltage limits.

Here is how it...

The inverter should be powered from a 12 Volts Source of DC and the required out put shouled be 220 Volts AC.

Get someone esle to do the damn dirty work for you!

K I have four 15V .15 amp solar modules. My question is: Since even in paralell these cells are weak can I charge AA batteries instead of a 12 volt battery? If so how? I tested the cells this morning, and each module shows about 9V even though at...

Silicon solar panels are basically current sources (up to their max power voltage), so you could connect a 15V panel to a 1.2 volt NiCd battery, and it would charge at 150 mA, or connect it to a 12 volt lead acid battery, and charge at 150 mA...

I have two trikle charge batteries set up now, each is connected to a solar cell charger. they run seperate inverters that put out 110 AC. How do I hook up more batteries on the system for longer use?

You can add batteries to help hold the voltage constant for a longer period of time by connecting them in a parrallel circuit with each other. This is done where you connect the positive terminal of one battery to the positive terminal of the next...
