rechargeable ones so that they can build up charge when the sun is out. then when it's dark you still have power. i know everyone hates cut and pastes but it's a good explanation;
How do Solar panels work?
SOLAR PANEL systems work by converting the suns energy into electricity, which is stored in a battery/ batteries. A regulator lies between the battery and the solar panel which protects the battery from over-charging. The regulator may also have discharging protection as draining the battery excessively will cause it long term damage. Energy can be taken out of the battery as required (12 or 24 Volts DC) using a transformer to convert to 220/240V if required. Control systems may shut down power draining equipment automatically to preserve the battery. Display units are available so that vital working of the solar panels and batteries can be monitored.

There are 2 types of solar panels. Type 1 is used to heat water which is then used in the house/building for heating etc. so no storage batteries are needed. Type 2 generates electricity from the suns light. This is usually used directly in the building (heating, lighting, powering appliances etc.) and any surplus can be exported to the antional grid. In remote areas, where the national grid is not available, or where the building owner wants to become less reliant on the grid, the surplus power could be stored in rechargeable batteries such as Le Clanche cells, or lead/acid storage batteries.

none solar panels generate electtricity
you cna store power generated from solar panels in batteries, but thats your choice. I think pretty much any rechargeable battery can be used (from Car type Lead Acid to NiMH/ L-Ion) You may need to select the 'right' type of lead acid battery. The choice of battery laregly comes down as to how you expect the power to be used (some batteries are great at low current long term usage, some are good at high current short burst usage)
In a well designed system you will need a regulator and charging sensor to make sure the batterires are not over charged

Solar panels collect energy from the sun.
They are stored in litheim type batteries

if it is a solar panel than it is charged by the sun, not batteries. just leave in the sun for 12 hours

I'm sure there are none as the idea of solar is from the sun so thats where the power comes from HELP ME !!!!!!!!!!

Just one big solar gaseous one found high above our heads during the hours of daylight.

Any sort can be used with the right control gear.

Any rechargeable cell. With suitable accesories of course.
