Solar Power Supply Sizing

I have a 120V single phase water pump & remote controlled RF receiver (level control in a storage tank) I need to drive by solar power.  My consumption runs around 1900 Watts/day in the dry season and 950 Watts/day in rainy season.

I want to install a solar panel (how many watts/type?)/solar charge controller (how many amps?)/lead acid car battery(will one Group 24 do it?)/inverter (pure sine or modified sine & how many watts?).

I would ask one of the local companies but this is just too small for any of them to be bothered with.  I'll just buy what I need on eBay and bring it down from the border and install it myself since it is for a non-profit organization.

Any solar engineers on here that could offer some advice to prevent me from buying the wrong stuff?

I'd look at the setups they use for RVs. They should be a good fit.

Just follow the instruction available on the internet including appropriate fusing and wire size for distance for example.
