Brooks new to solar

Hello ,I am overwhelmed by the options,the technology and the potential for low qualiyt/scams in this industry.

Can somebody assist me with some basics.

I have a plot with multiple tenants all using gas stoves and gas geysers. 

I intend to start up with one section of four tenants on a single phase through a master DB board.

There are four separate DB sub boards each unit has a micro wave,washing machine,router Tv ,lights and a few other light duty items.

The section also powers a pressure pump(.75kw) and gate motor electric fence and alarm.)

The usage was metered as follows;

• Daily peak 5.768 kw(although this included 2 no elec stoves which will be changed to gas.)
• Max per day 28.80kw
• Av daily use 25.8) kw

I hope to put in more panels to generate during the day with less emphasis on battery back (for now) for residential although i would like to add security lighting .

With the lighting is it better to use solar "street lights' or to add a few 100w lights to the above system.

I have budget restraints but if i can find a decent system with potential to upgrade later  ,any assistance will be greatly received.
TIA
