Financing & payment terms
PES accepts wire, ACH, and net-30 for approved contractors. Kits over $50k qualify for freight-inclusive project pricing and 25/25/50 milestone payments (deposit, ready-to-ship, delivery). The Federal ITC (30%) is claimed by the end owner in the year of PTO; commercial installs also qualify for 5-year MACRS accelerated depreciation. Consult your CPA — PES does not provide tax advice.
How much power does a 4 kW residential kit produce annually?
At a US average of 4 sun-hours per day and a 0.85 system derate, a 4 kW kit generates about 4,964 kWh per year — enough to cover roughly 40% of a typical 12,000 kWh/yr household load.
Do I need a service upgrade for a 4–6 kW residential kit?
Not usually. Kits at 6 kW or less on 120/240 V single-phase service typically fit under existing 200 A panels with a straightforward AC combiner or backfeed breaker. Confirm with your AHJ and read our Wire Size Calculator for feeder sizing.
Is the battery included in the kit price?
Yes — every PES kit at this size ships with an LFP battery bank sized to the system (typically 5 kWh at the 4–6 kW tier). This lets you cover essential loads during a grid outage.
Can I install this myself?
PES Supply sells to licensed contractors; some homeowner-friendly kits qualify for owner-permit install where allowed by AHJ. All kits include full documentation, but permitting and interconnection must follow NEC 690 and your local rules.
