The reduction, elimination or expiration of government subsidies and economic incentives for on-grid solar electricity applications could reduce demand for solar PV systems and harm our business.

Current report

The market for on-grid applications, where solar power, on a standalone basis or paired with energy storage systems, is used to supplement a customer’s electricity purchased from the utility network or sold to a utility under tariff, depends in large part on the availability and size of government-issued subsidies and economic incentives that vary by geographic market. Because our customers’ sales of solar power are typically into the on-grid market, the reduction, elimination or expiration of government subsidies and economic incentives for on-grid solar electricity may negatively affect the competitiveness of rooftop solar electricity relative to centralized sources of electricity (including from conventional thermal or utility-scale renewable generation) and could harm or halt the growth of the solar electricity industry and our business.

Current report

National, state and local government bodies in many countries, including the United States, have provided incentives in the form of feed-in tariffs (“FiTs”), NEM tariffs and related policies, rebates, tax credits, tax incentives and others to system owners, distributors, system integrators and manufacturers of solar PV systems and battery energy storage systems to bolster the cost competitiveness of solar electricity in on-grid applications relative to the cost of utility power, and to reduce dependency on other forms of energy. Many of these government incentives expire, phase out over time, have limited funding allocations, that require renewal by the applicable jurisdictional authority, or are being changed by governments due to changing market circumstances or changes to national, state or local energy policy.

In July 2025, the OBBB was enacted, introducing material changes to clean energy tax credit programs that are significant to our business and may impact our financial condition, results of operations and future prospects. The OBBB scales back the ITC available under Section 25D of the Code for residential solar and storage systems purchased through cash or loans. Under the new law, the Section 25D credit will expire on December 31, 2025. In addition, the OBBB imposes new timing requirements for eligibility under Section 48E of the Code, which governs ITCs for leased solar and storage systems. Specifically, solar-only projects that do not commence construction within 12 months of the OBBB’s enactment must be placed in service by December 31, 2027 in order to remain eligible for the credit. Energy storage projects are not subject to this placed-in-service deadline; however, the ITC for storage systems will begin to phase down in 2034 — decreasing to 75% in 2034, 50% in 2035 and phasing out entirely by 2036.

Current report

The OBBB also amends the domestic content bonus credit rules for Section 48E projects. Projects commencing construction after June 16, 2025 must meet a 45% domestic cost threshold, up from 40. The OBBB also introduces new compliance requirements under the FEOC provisions for both Section 48E and the AMPTC under Section 45X. These provisions establish an escalating threshold of non-FEOC content that must be met by solar and storage projects beginning construction in 2026 and by manufactured components produced beginning in 2026. On July 7, 2025, the President issued an Executive Order directing the Secretary of the Treasury to issue updated guidance within 45 days on the “beginning of construction” requirements applicable to Section 48E projects. The Executive Order also requires the Secretary to implement the FEOC restrictions set forth in the OBBB. These legislative and regulatory developments may negatively impact our eligibility for certain tax credits, the attractiveness of our offerings to solar and storage system lease providers, and the overall demand for our products. If we are unable to meet the revised domestic content or FEOC requirements, our ability to qualify for these incentives could be impaired, which may adversely affect our revenue, gross margins, business operations and competitive position.

In addition, several European countries, including Germany, Belgium, Italy, the Netherlands and the United Kingdom, have adopted reductions in or ended their NEM or FiT programs. Certain countries have proposed or enacted taxes levied on renewable energy. These and related developments have significantly impacted the solar industry in Europe and may adversely affect the future demand for solar energy solutions in Europe, which could adversely impact our results of operations.

Current report

Among other government-established incentives, NEM and related policies have supported the growth of on-grid rooftop solar products, and changes to such policies may reduce demand for electricity from our solar service offerings. NEM is a tariffed utility rate program that permits a consumer to sell the excess solar energy that the consumer’s solar panels produce to the electric utility company at a predetermined price. The most basic type of NEM tariff pays consumers the retail rate for electricity that their solar panels export to the grid, less certain “non-bypassable” fees paid by the consumer. However, certain states have sought to move away from retail rate NEM crediting for compensating excess solar generation. For example, in December 2022, the CPUC adopted a “NEM 3.0” policy, also known as the Net Billing Tariff, that unbundles export compensation from retail rates and instead bases it on a tool called the Avoided Cost Calculator (“ACC”), which estimates the utility costs that are avoided by exports from distributed generation for each hour of the year. The CPUC did seek to ease the transition for the solar market by adopting small “adders” to the hourly ACC export values for the first several years of the tariff. Nevertheless, these ACC-based export compensation values are significantly lower than retail rates for most hours of the year and may therefore increase payback periods, and thereby reduce demand, for solar-only systems.

Similarly, in November 2023, the CPUC adopted changes to its “Virtual NEM” and “NEM Aggregation” programs that prohibit multi-meter commercial or agricultural property owners from netting solar energy generated at or adjacent to those properties against import charges recorded on the meters at the property, except for residential account holders in a multi-family residential property. These types of modifications to NEM policies have impacted and could further harm our business, both in California, where we have derived a significant portion of historical revenues in the United States, and in other state and national jurisdictions, if pursued there.

Current report

Reductions in, or eliminations or expirations of, governmental incentives (including the elimination of the ITC at the end of 2025) or NEM policies in regions where we focus our sales efforts could result in decreased demand for and lower revenue from solar PV systems, which would adversely affect sales of our products. In addition, our ability to successfully penetrate new geographic markets may depend on new countries adopting and maintaining tax credits, tax incentives, NEM policies, or other programs to promote solar electricity and storage, to the extent such incentives or programs are not currently in place. Furthermore, electric utility companies may establish rate structures or interconnection requirements that could be harmful to the solar industry and adversely affect our sales.

Current report

Changes in current laws or regulations or the imposition of new laws or regulations, or new interpretations thereof, in the solar energy sector, by federal or state agencies in the United States or foreign jurisdictions could impair our ability to compete and could materially harm our business, financial condition and results of operations.

Current report

There has been, and will continue to be, regulatory uncertainty in the clean energy sector generally and the solar energy sector in particular. Changes in current laws or regulations, or the imposition of new laws and regulations in the United States and around the world, could materially and adversely affect our business, financial condition and results of operations. In addition, any changes to the laws and implementing regulations affecting the clean energy sector may create delays in the introduction of new products, prevent our customers from deploying our products or, in some cases, require us to redesign our products.

Current report

For example, the recently enacted OBBB scales back the use of the ITC for residential solar, tightens domestic content rules and imposes new deadlines for projects to qualify for the ITC. Such actions could result in a decrease in demand for our technology offerings in the United States and other geographical markets, which would harm our business, financial condition and results of operations.
