Alter a small solar water pump to run off battery ?

I bought a small smaller pump off amazon (1.2 Watt Solar Power Water Pump Garden Fountain - for fountains, waterfalls and water displays)  the solar panel is crappy and very finicky ( cheep) and does not hold a charge .. I was hoping to alter the power source to another solar panel or add another panel that comes off those solar lights that holds a change .. Alternatively modify to use a battery source with a on off switch ..  I know I don't need to alter the pump just want a continuous  power supply. Current Specs that cam  with the unit : solar power supply 7 v 1.2 w ( if that !) power of pump 7v , 1.1 w/ max lift 100 cm / size of solar panel ( 100mm x 100m x 25 mm) / max outflow quality of pump 180lh max water height 30 60 cm ( if that!)

Use car radiators for solar collectors. Any advice?

I have salvaged 2 car radiators, they aren't leaky. I want to use them for active closed loop solar collectors. Any advice? My current plan is to put them on the roof (in a hot box), then plumb them into an old water heater in the attic. My hope is they can recirculate glycol in a closed loop, convection only, but I may need to install a thermostat and pump. Anyone have experience in this? I want to dump the heat to my 2 water heaters in the basement (they are plumbed in tandem, so I can use the 1st tank for solar boost and 2nd tank for final temperature control). Heat exchangers: either the Butler Solar Wand, or Brazed Plate Heat Exchanger (single or parallel). Differential Temperature Controller from Any advice or suggestions hugely welcome. thanks in advance, Chris

Hi guys can we charge battery with a 9v solar panel? Answered

Dear Fellas, I'm wondering if its possible to charge 3 batteries connected in series with 1.5v each rated at 1000mAh each using a solar panel with an output of 9-10volts .223A? Would the batteries burn or not? I have an experiment connecting my 9 v solar panel to the radio which requires only 4.5 volts my observations are as follows: The radio would work but only during day light. Also my problem is during the night I would have to use a battery. My question is if I would connect in parallel the solar panel to my niMH battery would it charge? Won't it burn the battery since my batteries has a total of 4.5 volts and my voltage input is around 9-10v? Thanks to you all,
