How NRG Clean Power compares: ranked #179 of 240 scored California solar installers, by Solar.com Installer Score.

Compare California installer reviews →

Why this differs from star ratings: most five-star reviews say “great company” and stop, and star averages reward that. These category scores only count reviews with concrete evidence, weighted by recency and the reviewer’s track record. A company can hold a strong star average while specific categories score lower; that gap is usually where the real story is. Categories with more complaints than praise are the questions worth asking any bidder, not necessarily dealbreakers.

Where NRG Clean Power builds

County-by-county activity from CPUC records through May 2026.

What this data covers: *Counts on this page, including the totals up top, come from investor-owned-utility interconnection records (SCE, SDG&E, PG&E). Work in municipal-utility territory, such as LADWP or city utilities, and outside California does not appear here, so this company's true totals are higher than shown. Unlike the county rankings, this profile also shows counties below the 250-install ranking floor.

NRG Clean Power reviews: what customers say

An independent synthesis of published customer feedback across Google, BBB, Trustpilot, and editorial coverage, updated September 10, 2026. Green marks praise, amber mixed experiences, red complaints.

Sales & proposal integrity

Sales Integrity5.9/10

Customers typically describe the front-end sales experience as professional and responsive, with some reviewers praising consultative sizing help and fair-looking proposals. But this category lands near market average because a sizable minority report that expectations set during sales did not hold up after signing, including allegations that key roof constraints, follow-through, or promised details were not clearly handled upfront.Solar.com's composite of published customer feedback, not a customer quote

Strong initial sales experience. Many reviews say the sales team was polished, responsive, and easy to work with early on. Several customers specifically appreciated a non-pushy approach and help sizing systems around real household usage.

Promises need to be documented. The main complaint pattern is that the experience changed after contract signing, with sales contacts dropping off and customers feeling that verbal assurances did not carry into scheduling or project execution. Some severe reviews describe undisclosed install constraints or later disputes over what had been promised.

Proposal quality varies by rep. Some customers say estimates were fair and accurate, while others describe cookie-cutter pitches or difficulty getting direct answers to technical questions before signing. That split keeps this category in mixed territory rather than clearly strong.

Price & financing transparency

Price Transparency4.8/10

Customers typically describe pricing transparency as one of NRG Clean Power's weaker areas. While some reviews praise fair quotes, consultative financing discussions, and projects that stayed on budget, the larger concern is around omissions, surprise costs, and rebate-related misses that left some customers feeling the low initial quote did not tell the full story.Solar.com's composite of published customer feedback, not a customer quote

Disclosure concerns outweigh praise. The most consistent criticism is that quoted pricing did not always reflect the full scope, with complaints about missing components, later-added costs, or financial terms customers felt were not fully clear upfront. Several severe reviews describe concrete financial harm tied to surprise expenses or missed incentive timing.

Some customers found pricing competitive. A meaningful share of reviews still say NRG offered fair or better-than-competitor pricing, and a few customers report that their final project stayed within the agreed budget. Financing guidance also gets positive mentions when reps offered multiple lending options instead of steering customers to one product.

Low quote can require scrutiny. A recurring theme is that shoppers attracted by an inexpensive proposal later felt they needed to closely inspect line items and scope details. Reviews suggest buyers should verify equipment inclusions and any assumptions before signing.

Communication & coordination

Communication6.4/10

Customers typically describe communication as one of NRG Clean Power's stronger areas, with many naming individual staff members who kept them updated through permits, repairs, and activation. Even so, the record is not spotless: when coordination breaks down, complaints center on handoff problems after signing, stalled projects, and customers having to push for answers.Solar.com's composite of published customer feedback, not a customer quote

Frequent praise for responsiveness. This is one of the company's better-scoring categories, and many reviewers say advisors, permit staff, and support contacts were attentive, quick to respond, and proactive with updates. Named employees are often credited with keeping projects moving and answering questions clearly.

Breakdowns often happen at handoffs. Negative reviews commonly describe a smooth sales phase followed by poorer communication once the project moved into coordination and scheduling. Some severe complaints say progress stalled, updates stopped, or customers had no clear owner for the next step.

Individual service can outweigh process gaps. Even mixed reviews often distinguish between strong effort from specific employees and weaker back-end processes. Customers frequently say the people were helpful, but the coordination system itself could feel disjointed.

Timeline reliability

Timeline Reliability5.3/10

Customers typically describe timelines as inconsistent. Plenty of projects were completed in a reasonable window, especially when permit and utility steps moved cleanly, but this score sits below market typical because delays, stalled coordination, and missed timing around incentives show up too often to ignore.Solar.com's composite of published customer feedback, not a customer quote

Delays are the main risk. The leading complaint is that projects took longer than expected once they reached coordination, permitting, or activation. Some severe reviews describe long stalls, customers having to keep pushing the project forward, or timing misses that cost them rebate opportunities.

Some projects moved on schedule. There are still many positive reviews saying work began promptly after approvals and wrapped up in a timely manner. Customers who had strong project managers often describe good updates during permit or repair delays rather than silence.

Complex projects can depend on active follow-up. A recurring theme in mixed reviews is that NRG usually gets there eventually, but homeowners may need to stay engaged and track details themselves. That makes the timeline experience feel less predictable than top-tier installers.

Workmanship & site care

Workmanship5.9/10

Customers typically describe installation quality as acceptable to good overall, with many praising clean work, solid equipment, and smooth installs. But the score stays only average because a notable minority report avoidable jobsite problems, including cosmetic damage, incomplete work, and inspection failures.Solar.com's composite of published customer feedback, not a customer quote

Many installs are described as clean and professional. A majority of reviews in this category praise neat workmanship, quality panels, and efficient crews. Some customers say the finished system looked great and the install team left a strong impression.

Serious site issues appear in the complaint set. The negative pattern is more than minor punch-list work: some severe reviews describe disconnected household wiring, safety concerns, repeated failed inspections, and damage to the home that customers say was not handled well. Others mention delivery or installation mistakes that created unnecessary disruption.

Execution seems uneven across projects. Taken together, reviews suggest workmanship can be very good on some jobs but inconsistent on others. This looks less like a universal quality problem than a process-control issue that shows up on a meaningful minority of installs.

Long-term support & performance

Long-Term Support7.2/10

Customers typically describe post-install support as better than average, especially when troubleshooting or warranty claims are actively owned by a responsive service contact. Still, some cases involved prolonged diagnostics, repeated part replacements, or periods of underperformance before the system was fully stabilized.Solar.com's composite of published customer feedback, not a customer quote

Support responsiveness is a relative strength. Many reviewers say NRG was helpful after installation, with fast callbacks, remote troubleshooting, and persistent follow-through on warranty issues. Several customers specifically praise service staff for keeping them informed until systems were back online.

Some fixes took too long to fully resolve. Negative reviews in this category usually do not say support was absent, but that it took too many visits, too much testing, or too long to identify the real cause of poor production or communication faults. A few severe cases describe extended downtime before resolution.

Good recovery can improve a bad start. Several mixed reviews say the company eventually made things right through stronger communication, replacement parts, or compensation for downtime. That pattern helps this category score above average even though some service cases were drawn out.

Bottom line: NRG Clean Power reviews point to strongest relative performance in communication and long-term support, where many customers praise responsive staff, persistent follow-through, and a 12-year, 6,200-install track record in utility records. The weakest area is price and financing transparency, with too many complaints about incomplete scope, surprise costs, or missed rebate timing. Overall, customers often like the people they work with, but the company appears less consistent on back-end execution, scheduling, and upfront clarity than the better-reviewed installers in the market.

Important context: this chart shows investor-owned-utility records only. Companies that shift work toward municipal-utility territory (LADWP and city power departments) or other states will show declining bars here even while building steadily elsewhere, and 2025-26 records also lag real installation dates. Treat this as a partial window, not the company's full trajectory.

Methodology: Counts are residential PV interconnections in investor-owned-utility territory (PG&E, SCE, SDG&E) per CPUC Rule 21 public records through May 2026. Postal and name variants are merged. Municipal utility territory such as LADWP, Glendale, Pasadena, Burbank, Anaheim, and Riverside Public Utilities is not included in those CPUC counts. Counts show recorded installations, not quality ratings. Reported costs are self-reported on owned-system interconnections. No installer can pay for placement.
