The 400-500Wh generated monthly by these systems is great for eliminating the impact of a hot tub or running the air conditioner. A 4000W Complete Solar Kit could offset 50% of medium user's consumption.


MODULES: Your Complete Solar Kit will contain 15 to 18, 250 Watt modules.

INVERTERS: The heart of your Complete Solar Kit is the SMA Sunnyboy Grid Tie Inverter. We’ve installed 1000’s of these. They are really easy to install (watch video) and although they have almost 0 failure rate, if you have a problem, the SMA tech support desk is reachable in under 4 rings and you’re talking to a human in less than 60 seconds. These inverters are backed by world class technical & customer support. They come with an extendable 10 year warranty. I’ve got 2 of these units on my house. They’re the best.

WIRING: During our design conversations with you, we will determine the approximate lengths and then add a bit more to your spools. By knowing how much current has to be carried and how far, we can determine the proper gauge of conductor required. Your home run wires under the array will be crimped and labeled according to your home run map. All of your grounding wire is included as well.

All the home run wires All the DC wire from the j-box to the Inverter All the AC wire from the inverter to AC Disconnect and to the Main Service Panel are included. This is your L1, L2, N and green. All your grounding wires are included too. This is your EGC and GEC.

BALANCE OF SYSTEM: Our Complete Solar Kits are distinct from anything available to a homeowner on the internet. Your solar kit comes with a super complete Balance of System. All the 80 little parts and pieces that make up your solar system come in your kit. Don't be fooled by other companies claiming COMPLETE kits, read closely and you'll see the Bill of Materials is just modules, inverters, racking, and a few token miscellaneous items.
