Hiring a solar company in Rocklin

In Rocklin, a solar company files a rooftop panel job through SolarAPP+ for an extra $25, then pulls the City permit and books inspections in eTRAKiT; any job that includes a battery, and any owner-builder job, takes the City's standard review instead. PG&E delivers your power and Pioneer Community Energy supplies it, with a small bonus on year-end surplus. Get three written bids and compare them on the checks below.

Start with your Rocklin electricity bill

Rocklin’s electricity information identifies PG&E delivery and a choice of Pioneer Community Energy generation. Pioneer has separate guidance for legacy NEM and Solar Billing Plan customers. Read the enrollment and generation provider on your bill before comparing export credits.

Rocklin's online permit, and what it leaves out

Rocklin's online solar page walks a contractor through six steps: create a SolarAPP+ account, submit the plans, pay SolarAPP+'s $25 fee, upload the approved plans to the City's eTRAKiT system, pay the City's own permit fees, and, once eTRAKiT issues the permit, install and schedule inspections through eTRAKiT or by calling the Building Division at (916) 625-5120. City permit fees and inspections apply in addition to the SolarAPP+ charge.

The page is explicit about two exclusions: owner-builder projects and projects that include an energy storage system are not eligible for SolarAPP+ at this time. So a Rocklin quote for panels alone and a quote for panels plus a battery follow different permit paths, and the second one takes longer. Ask each bidder which path it has assumed and whether its timeline allows for standard review if a battery is in the scope.

What Pioneer adds for a Rocklin solar home

Pioneer Community Energy has served Rocklin since its 2018 launch alongside Auburn, Colfax, Lincoln, Loomis and most of unincorporated Placer County. A system installed since April 15, 2023 is on the Solar Billing Plan, where Pioneer values exports at a variable export rate and positive charges are paid monthly; older systems on net energy metering earn retail credits that roll forward month to month.

Pioneer reviews each solar account over the past twelve months during the March or April billing cycle and pays Net Surplus Compensation at half a cent per kWh more than PG&E's rate. A surplus worth more than $50 is paid by check; a smaller one becomes a bill credit. Because that bonus is small, the decision rests on how much of your own usage the system covers, so ask each bidder to show monthly production against your monthly use.

What a Rocklin quote needs to explain

A comparison to ask for

If you compare a purchase proposal with Pioneer’s GridGen program, separate system ownership from the utility bill. GridGen describes solar-plus-storage and battery-retrofit options with charges on the utility bill and its own transfer/buyout terms. Compare total obligations, who services the system and what happens when the home is sold.
