Trends in residential solar finance, equipment and maintenance

Solar informational site SolarReviews released its annual survey, sharing results gathered from a group mostly represented by residential solar installers, as well as commercial installers, equipment providers, and utility-scale installers. SolarReviews operates a Solar Calculator that enables prospective customers to have a snapshot of the benefits of adding solar to their roof based on customized data for their area.

Finance 

With higher financing costs industry-wide, 54% of U.S. installers said customers were less likely to take a solar loan over the past year, while cash deals are up. About 49% of sales reported were cash deals, while 41% were loans. HELOC, PACE loans, power purchase agreements, and leases combined for 10% of reported solar sales. 

The top financing providers used were Credithuman (15%), Mosaic (14%), Sunlight Financial (9%),Dividend (8%), and Clean Energy Credit Union (8%). 

Typical loans for loaned systems varied widely depending on whether dealer fees were assigned. Average terms are seen below.

Heightened cost of finance has pressed the residential solar industry. About half (49%) of installers said demand went down in 2023 versus 2022.

In California, where rates paid for exporting solar production to the grid were slashed by about 80%, about 69% of installers reported lower sales in California in 2023 versus 2022. However, 68% of installers reported including battery energy storage with their solar installation, about double the national average. Installers report a median payback period of eight years for solar systems with a battery, while standalone solar systems have a longer median payback period of about 10 years.

California was not the only state to cut rates for solar exports, a process known as net metering. Georgia, Arizona, Kansas, Arkansas, and Wisconsin all noted an increase in installed systems not tied to a net metering agreement.

Top products

As for the top equipment brands in residential solar, SolarReviews surveyed installers based on five criteria of performance and quality, brand name reputation, product warranty, pricing, and product availability from distributors. Based on the five criteria, SolarReviews listed Qcells as the top performing panel brand.

Installers said the top five most-used panels were Qcells (53%), REC (41%), Canadian Solar (35%), Mission Solar (29%), and JinkoSolar (20%). About 19% of solar installers offer one panel brand, while the majority provide alternative options to meet the needs of their customers.

For inverters, the top five most-used were Enphase (62%), SolarEdge (43%), SMA (23%), Sol-Ark (21%), and Tesla (21%). Tesla made a notable leap up into the top five, gaining a larger market share than Fronius and Generac.

Enphase was also listed as the most commonly used battery energy storage provider, offered by 46% of installers. This was followed by Tesla (42%), SolarEdge (35%), FranklinWH (29%), and Fortress Power (18%). A sizeable market share was also held by SunPower, Generac, LG Energy Solution, and HomeGrid.

Maintenance

Given that solar is often a 25-year investment, post-installation services are a critical feature in a solar agreement. About 96% of installers have access to system monitoring, while 63% said they proactively check their customers’ installations at least once per quarter to ensure they are working.

The most common reasons for service, in order, were inverter hardware failures and replacement, inverter software and setup issues, battery software updates, communications and monitoring fixes, roof leaks, battery hardware failure or replacement, wiring issues, and broken or underperforming panels.

“Fortunately, when issues do occur, they are often covered by some type of warranty, leaving only 15% of cases where the customer is responsible for repair costs,” said SolarReviews.

Outlook

The residential solar industry looks to recover from a rocky 2023, where growth was slowed by high finance costs and unfavorable policy changes like the reduction of net metering rates.

“Some solar businesses are still reeling from the events of 2023. 22% of solar businesses say they have concerns that make them unsure whether they can stay in business in the coming six months,” said SolarReviews.

Despite this uncertainty, residential solar installers appear to have a good outlook for 2024. About 54% of surveyed installers said they expect to sell more solar in 2024, and an additional 23% said they think they will be able to maintain the same level of business next year.

Notably, surveyed installers listed pv magazine as the top trusted media platform for solar news and analysis, with 52% responding we are the preferred source. The marks the second year in a row as the most-trusted media source. We thank you for your continued readership.

Edge AI Emerges as Critical Infrastructure for Real-Time Finance | PYMNTS.com

Edge AI Emerges as Critical Infrastructure for Real-Time Finance | PYMNTS.com

The financial sector’s honeymoon phase with centralized, cloud-based artificial intelligence (AI) is meeting a hard reality: The speed of a fiber-optic cable isn’t always fast enough.

For payments, fraud detection and identity verification, the milliseconds lost in “round-tripping” data to a distant server represent more than just lag — they are a structural vulnerability. As the industry matures, the competitive frontier is shifting toward edge AI, moving the point of decision-making from the data center to the literal edge of the network — the ATM, the point-of-sale (POS) terminal, and the branch server.

From Batch Processing to Instant Inference

At the heart of this shift is inference, the moment a trained model applies its logic to a live transaction. While the cloud remains the ideal laboratory for training massive models, it is an increasingly inefficient theater for execution.

Financial workflows are rarely “batch” problems; they are “now” problems. Authorizing a high-value payment or flagging a suspicious login happens in a heartbeat. By moving inference into local gateways and on-premise infrastructure, institutions are effectively eliminating the “cloud tax” — the combined burden of latency, bandwidth costs and egress fees. This local execution isn’t just a technical preference; it’s a cost-control strategy. As transaction volumes surge, edge deployments offer a more predictable total cost of ownership (TCO) compared to the variable, often skyrocketing costs of cloud-only scaling.

Coverage from PYMNTS highlights how financial firms are transitioning from cloud-centric large models toward task-specific systems optimized for real-time operations and cost control.

From Cloud-Centric AI to Decision-Making at the Edge

The first wave of enterprise AI adoption leaned heavily on cloud infrastructure. Large models and centralized data lakes proved effective for analytics, forecasting and customer insights. But financial workflows are not batch problems. Authorizing a payment, flagging fraud or approving a cash withdrawal happens in milliseconds. Routing every decision process through a centralized cloud introduces latency, cost and operational risk.

Edge AI moves inference into branch servers, payment gateways and local infrastructure, enabling systems to decide without every query circling back to a central cloud. That local execution is especially critical in finance, where latency, privacy and compliance are business requirements.

Real-time processing at the edge trims costly round trips and avoids the cloud bandwidth and egress fees that accumulate at scale. CIO highlights that as inference volumes grow, edge deployments often deliver lower and more predictable total cost of ownership than cloud-only approaches.

Banks and payments providers are identifying specific edge use cases where local intelligence unlocks business value. Fraud detection systems at ATMs can use facial analytics and transaction context to assess threats in real time without routing sensitive video data, keeping customer information on-premise and reducing exposure.

Edge AI also supports smart branch automation, real-time risk scoring and adaptive security controls that respond instantly to contextual signals, functions that centralized cloud inference cannot economically replicate at transaction scale.

Edge AI delivers clear operational and governance advantages by reducing bandwidth use, cloud dependency and attack surface. Keeping decision logic local also simplifies compliance by limiting unnecessary data movement, a priority for regulated financial institutions.

Edge AI Stack Is Coalescing Across the Tech Industry

The broader tech ecosystem reinforces this trend. As reported by Reuters, chipmakers such as Arm are expanding edge-optimized AI licensing programs to accelerate on-device inference development, reflecting growing conviction that distributed AI will capture a larger share of enterprise compute workloads. Nvidia is advancing that shift through platforms such as EGX, Jetson and IGX, which bring accelerated computing and real-time inference into enterprise, industrial and infrastructure environments where latency and reliability matter.

Intel is taking a similar approach by integrating AI accelerators such as its Gaudi 3 chips into hybrid architectures and partnering with providers including IBM to push scalable, secure inference closer to users. IBM, in turn, is embedding AI across hybrid cloud and edge deployments through its watsonx platform and enterprise services, with an emphasis on governance, integration and control.

In financial services, these converging moves make edge AI more than a deployment option. It is increasingly the infrastructure layer for enterprise AI, enabling institutions to embed intelligence directly into transaction flows while maintaining discipline over cost, risk and operational continuity.

Bank of Korea needs to remain wary of financial stability risks, board member says

SEOUL, Dec 23 (Reuters) – South Korea’s central bank needs to remain wary of financial stability risks, such as heightened volatility in the won currency and upward pressure on house prices, a board member said on Tuesday.

“Volatility is increasing in financial and foreign exchange markets with sharp fluctuations in stock prices and comparative weakness in the won,” said Chang Yong-sung, a member of the Bank of Korea’s seven-seat monetary policy board.

The won hit on Tuesday its weakest level since early April at 1,483.5 per dollar. It has fallen more than 8% in the second half of 2025.

Chang also warned of high credit risks for some vulnerable sectors and continuously rising house prices in his comments released with the central bank’s semiannual financial stability report.

In the report, the BOK said it would monitor risk factors within the financial system and proactively seek market stabilising measures if needed, though it noted most indicators of foreign exchange conditions remained stable.

Monetary policy would continue to be coordinated with macroprudential policies, it added.

The BOK held rates steady for the fourth straight monetary policy meeting last month and signalled it could be nearing the end of the current rate cut cycle, as currency weakness reduced scope for further easing.
Following the November meeting, it has rolled out various currency stabilisation measures.

The BOK’s next monetary policy meeting is in January.
