Here is a list of the pv system basics.
Basic solar system diagram.
Dividing by 50 depth of discharge as you choose flooded that is 18000 0 5 36000wh or divde by 0 8 if for agm batteries that is 18000 0 8 22500wh.
The solar panels a charge controller two 6 volt golf cart batteries and a small inverter.
First lets face it.
To the left are the basic components required to produce electricity from the sun.
Basic concepts of solar panel wiring aka stringing to have a functional solar pv system you need to wire the panels together to create an electrical circuit through which current will flow and you also need to wire the panels to the inverter that will convert the dc power produced by the panels to ac power that can be used in your home and.
Mounting your pv panels is of critical importance.
First is solar power worth it.
Solar panel pv panel 2 charge controller.
We focus primarily on solar and will therefore simply use the phrase solar energy system or solar power system.
Our simple home solar power system is comprised of four basic components.
Their placement and mounting affect your system performance more than any other facet of the job.
Sixteen panel solar system.
The cost of this complete solar system in today s pricing for the components was about 1200.
For an off grid solar system you need four basic components.
I am not sure why you said 2pcs of 120ah12v battries in series.
Although the solar arrangement in the solar panel wiring diagram above isn t the best for the long term life of your battery because there is more stress on the system it does provide a way to reach the capability of a bigger system without having to add more panels batteries.
Solar power system diagram.
Only you have to know some basic electrical and math for designing the entire system.
Basically that is 1500w 12 18000wh.
Pv panels which cost anywhere from 2 40 per watt to over 5 per watt are the single biggest expense of a pv system.
Instead of this i have attached links of my other instructables to make the charge controller and energy meter.
The basic solar power system diagram minus the various circuit breakers combiner boxes cables shunts grounds and other details.
I m posting this for the beginner.
