need help sizing solar panel..

[Jimmy Reza de la Turin]

Hello...
I want to run a pond pump in my backyard
as well as a couple of circuits of landscape 12 v lighting
(probably 60 watts each circuit)

The pond pump is 145 Watts AC
the landscaping lights are

The pump is to be run all day 24x7
and the lights only at night for about 5 hours

I plan on getting two 12 volt marine deep cycle batteries
to store the energy...

what do i need to buy in terms of solar panel (how many watts
should cover this scenario)

and do i need a converter or inverter for the AC pump

thanks in advance

Pump 145W x 24 = 3480Wh/day

Lights 60W x 2 x 5h = 600Wh/day

Total daily load = 4080Wh

The thought crosses my mind that 18 - 80 Watt panels may just be a bit more than you care to invest in.

I would suggest that you look at an automotive electric fuel pump and led lights for your project.

Example: 13 - 18 led lamps draw 2.34 amps or 28 watts as apposed to your choice at 120 watts (10A)
