Need help designing off grid PV system for outdoor lighting & landscape lighting

mehrzad

Hello all. I have a semi large property approx 4 acre. I like to design and install a DIY PV system to power my landscape/outdoor lighting and water fountain, etc. I will be using all 12v dc components (LED lights, water pumps, fans....) Any recommendation on a turn key design? Also how can I calculate my drop on power if I am running the 12 V DC on long distance, say 200 ft?... Thanks

you need to determine the loads presented to the system and for how long they will each be running for a whole day. this will determine what is needed for storage as well as what is needed in pv to charge it. i do trust the diy installation does not mean you are building pvs as i will advise against doing this.

once all the pertinent info is collected and you determine a good system the wiring can be figured using the v drop calculator in my signature line.

You may find that using a small 120VAC inverter, will cost less than the wire gauge needed for the long runs @ 12VDC.
