DIY Solar Electrical Installation for Grid Tied Electrical using Enphase Micro inverters
1. I am not an electrician and I do turn off the panel at the main when I do panel work.
2. Grid Net Metering (Turning backwards) requires permits and inspections
a. NEC code it is a bit simpler with Micro Inverters because no DC to a string inverter
b. You will likely be using a PV Tool Kit and pulling a permit with your city
c. You will be filling out and signing agreements with your electrical company
d. $460
3. Plans
a. Solardesigntool.com https://get.solardesigntool.com/
b. PV Tool Kit – California Solar permitting guide book http://www.opr.ca.gov/docs/Solar_Perm...
c. They call out EMT conduit and define the electrical components
d. Plan for expansion Run extra wires heaver gage wire more wire you want not to have to touch the grid portion. It will have relatively low cost to add additional panels if you don’t need to touch the Feed to the roof
4. Should you do the Electrical work yourself?
a. $2000 labor + $500 parts r cost for Electrical is a fixed component no matter how many panels you run. I have 2.7kw $4,500 in components but the electrical labor is $2,000. It could take my panels up to 2 years to pay for the electrical work!
b. Breakdown
i. Panel work show breaker at bottom
ii. Mounting Components and wiring
iii. Riser
iv. Roof
c. Challenges
i. Panel Interface Panel breaker
ii. Working with EMT
5. EMT Bending
a. Paint emt but keep ends free of paint
b. Emt cost is cheap. Videos on bending http://sparkychannel.com/
c. Apps on phone ibend and quickbend iphone apps
d. Do a ton of practice bends
e. Do practice sometimes during one of your production bends
f. Parts Connectors, couplers and straps
g. Over buy parts and return at the end of your project
h. Tools – bender , cutter use popular bender
