I have a van which has a solar panel on the roof. There are a few small lights which are always elluminated that are connected to the solar panel operation. The van is used mainly for camping and as the price of gas climes, the use of the van declines. The van is in a garage, so, no light for the solar panel. I do run the vehicle from time to time; however, not long enough to charge the batteries. My question: will a light bulb over the solar panel charge the battery. If so, what would be the minimum size?
Yes, but the efficiency of solar cells is terrible. Its one thing to use free sunlught to charge the cells, its another to have to pay the electric company to do it. If you can access the batteries in the solar rig easily and they are in the correct voltage range, I think you would be better off getting a battery tender (trickle charger). Just let the van sit outside until the batteries are fully charged, then connect the battery tender to keep it fully charged.

My wives car battery kept going dead and had to be recharged often because it wasn't driven enough to keep the battery charged. A friend told me about the Solar Panel and I bought one and haven had a problem since. It really works great not only for the car battery but also for Trucks, boats, camping gear and RVs that have a 12V Battery. It is available at Harbor Freight Stores. Copy this site
A solar powered electric fence energizer usually contains a battery for energy storage. The solar panel collects the energy from the sun and charges the battery. Lead acid batteries, which are used in solar fence chargers, typically last around 3 years, or around 1,000 days of charging.

leave in situ and put on charge with a 4 amp charger and leave it alone for a good two days to de sulphate the plates and charge the battery ,disconnect the earth lead so you dont damage any computer with a slight AC ripple you always get with any battery charger unless its a solar panel
Take your battery in for testing after charging it. Then, to avoid pulling the Alternator for nothing, drive to a local Autozone, Advance, or Oeilys and ask them to check your charging system on the Van.
Consider taking an extra battery if you have one to fit, so you can get back home after the test. Run the van with the charger connected until you get good heat, then reduce the blower fan speed to minimum. Then disconnect charger.
If you are still stuck on the road, jumpstart the van until it is warm, using the jump car to charge the battery so you can go home and try again. Just leave the battery jumpers connected to the struggling van battery a few minutes so the old battery has a chance to charge.
Right disconnect the battery and see if stops as i have had this problem before and the cause is a solar panel in the sun roof will cause this motor to run to keep the interior temperature down on a hot day .This had me well baffled last week with a AUDI A8 i spent a short while thinking what the noise was then when i found the noise was the blower motor i started to try to think of all the causes i think off then i looked for the fuse board when i thought disconnect the battery first --- and the noise still continued and it was hot over 30? C so i took my overhauls off and threw them over the roof getting ready to look for a second battery somewhere and the noise stopped ,removed the overhauls and it started again so look at the sun roof and it had a solar panel in the glass .BOY DID I FEEL LIKE A IDIOT
absolutely. solar chargers are out there, most electronic shops will have them. get at least a 7 watt one. or a new deep cycle battery will easily handle being in storage for a week. so long as doors are all shut tight.
