Why now · Rhode Island

Your rate nearly doubled in 15 years.

Rhode Island's residential electric rate climbed from 17.5¢/kWh in 2010 to 31¢/kWh by 2025. A typical 8 kW rooftop solar system locks your rate at a fraction of today's grid price for the 30-year life of the array.

What an 8 kW REG solar install actually pays back.

An 8 kW REG-enrolled array on a Providence home produces ~9,200 kWh/yr at the locked Renewable Energy Growth ceiling rate of $0.34/kWh for 15 years. That payment, layered with the RI sales tax exemption and Section 48 ITC pass-through on lease/PPA, puts every kWh you generate to work for the next 15 years.

04 · Install Timeline

From first call to permission to operate.

A typical Rhode Island residential solar install runs 10–14 weeks from site survey to grid interconnection. Permitting and inspection sit on most of that runway.

01.
Site survey & system design
Contractor evaluates roof orientation, shade, structural load, and produces a system design with an annual production estimate.
Week 1
02.
Permitting & utility interconnection app
Building permits filed with the town; interconnection application filed with the local utility. Review typically runs 6–8 weeks.
Weeks 2-6
03.
Equipment procurement
Panels, inverter, racking, and balance-of-system components ordered after permit approval. Lead times depend on configuration.
Weeks 5-8
04.
Installation
Most residential installs complete in 1–3 days on-site. Building permit inspection follows a few days later.
Weeks 8-10
05.
Permission to operate (PTO)
Final utility inspection and net-metering activation. PTO is when the system legally begins exporting and earning credits.
Weeks 10-14

06 · Questions Homeowners Ask

The honest FAQ.

Actual questions that come up in the first installer conversation, answered for a typical Rhode Island homeowner in 2026.

Should I pick REG or net metering?

For most RI homeowners, REG pays more over the contract life, but the decision is binding for the contract term. We model both scenarios during your design phase and show you the 20-year financial comparison before you commit.

What if RI Energy changes the REG rate later?

Your rate is locked at interconnection for the full contract term (15 or 20 years). Rate changes affect new enrollments only.

Are REG rates going up or down?

2026 rates ($0.27-0.34/kWh) are strong. Some pending legislation has proposed adjustments to REG, so apply early to lock in the current rate while it's available.
