The Americas collectively account for over 340 GW of installed solar capacity — yet the region has no unified compliance framework. A project in São Paulo operates under ANEEL’s Resolution 1000/2021. A system in California must navigate NEM 3.0 export rates and the specific permit requirements of the local AHJ. A commercial installation in British Columbia faces BC Hydro’s net metering rules, which are changing in July 2026. Knowing which rules apply — and where they are shifting — is the difference between a profitable project and one that misses incentive windows or fails interconnection.
This guide covers the solar compliance landscape across 8 Americas markets: USA, Canada, Brazil, Mexico, Chile, Colombia, Argentina, and Peru.
USA Residential ITC Expired December 31, 2025
The Section 25D residential Investment Tax Credit — which gave US homeowners a 30% federal tax credit for rooftop solar — expired at year-end 2025. The Section 48E commercial and utility ITC remains at 30% base rate through 2032. Any solar installer quoting US homeowners must adjust financial models accordingly.

The USA and Brazil together represent the vast majority of Americas solar capacity. Both markets are expanding rapidly, but their regulatory structures are entirely different. Use this guide as your starting point, then drill into the country-specific sections and SurgePV’s dedicated compliance pages for permit-ready detail.
United States: The World’s Second-Largest Market
The US installed 43 GW in 2025 — the fifth consecutive year as the top source of new US power capacity — bringing cumulative installed solar to 279 GWdc. With the Inflation Reduction Act (IRA) locking in a 30% commercial ITC through 2032, SEIA projects cumulative capacity reaching 769 GW by 2036.
SurgePV has 42 dedicated USA compliance pages at /solar-compliance/usa/ covering NEC Article 690, state guides, AHJ guides, and design tools.
The US Compliance Stack
US solar compliance operates on three levels simultaneously:
| Level | Who Sets It | What It Covers |
|---|---|---|
| Federal | NFPA (NEC) + IRS (IRA) | Electrical safety + tax incentives |
| State | State legislature / PUC | Net metering, interconnection, licensing |
| Local | AHJ (city/county) | Building permits, plan review, inspections |
NEC Article 690 is the national electrical baseline. Most US states are on NEC 2017 or 2020 as of 2026, with some jurisdictions adopting NEC 2023. The key sections every US installer must know:
- 690.7 — Maximum system voltage (600V residential, 1,000V commercial)
- 690.8 — Conductor sizing (125% of Isc)
- 690.12 — Rapid shutdown for building-mounted systems
- 690.31 — Wiring methods (PV wire, USE-2, conduit)
ITC Status: 2026
| System Type | ITC Rate | Basis | Expires |
|---|---|---|---|
| Commercial (Section 48E) | 30% base | Investment value | 2032 |
| + Domestic content adder | +10% | US-made components | 2032 |
| + Energy community adder | +10% | Coal/oil/gas community zones | 2032 |
| + Low-income community adder | +10–20% | Qualifying census tracts | 2032 |
| Residential (Section 25D) | Expired | — | Dec 31, 2025 |
Commercial and utility-scale projects can stack adders to reach effective rates of 40–50%. The SurgePV generation and financial tool calculates ITC-adjusted ROI, payback periods, and NPV for US commercial projects.
California NEM 3.0: The Biggest US Compliance Shift
California’s NEM 3.0 (effective April 15, 2023) fundamentally changed the economics of new residential and commercial solar in the state. Under NEM 3.0:
- Export compensation dropped from retail rate (~$0.30/kWh) to market-based “Avoided Cost Calculator” rates averaging $0.02–0.05/kWh
- Battery storage payback improved significantly — NEM 3.0 was designed to incentivize storage
- Systems grandfathered under NEM 2.0 retain their tariff for 20 years from PTO date
New California solar projects commissioned under NEM 3.0 typically require a paired battery system to remain financially viable for customers. The solar design software used for California projects must model time-of-use export rates, not simple retail rate offsets.
US State Net Metering: Wide Variation
While FERC sets federal interconnection standards, net metering is entirely state-controlled. States like Texas have no statewide net metering mandate — rules are set by individual utilities. Florida, Arizona, and North Carolina have active retail-rate net metering programs. Always verify the current tariff with the serving utility before finalizing a project pro forma.
US Permitting
Every US solar installation requires a permit from the local AHJ. Key permitting tools:
- SolarAPP+ (DOE/NREL): Over 250 jurisdictions use this automated plan review platform for residential systems under 15 kW — permits issued in minutes rather than days
- California AB 970: Standardizes residential solar permit applications under 10 kW statewide
- Expedited permit laws: Many states have passed legislation requiring AHJs to provide a streamlined permit process for small solar systems
For detailed US state-by-state rules, permit timelines, and interconnection procedures, see the full USA compliance hub.
Canada: 9 Utility-Specific Guides
Canada has no national solar net metering standard. Each province, and often each utility within a province, sets its own program rules. The federal government provides a 30% Clean Technology Investment Tax Credit (ITC) for solar assets placed in service from 2024 onward — applicable to both residential and commercial systems.
SurgePV maintains 9 dedicated Canada compliance guides at /solar-compliance/canada/:
| Utility / Province | Key Rule | Guide |
|---|---|---|
| BC Hydro | Net Metering — RS 2289 | BC Hydro guide |
| Hydro One (Ontario) | Net Metering up to 500 kW | Hydro One guide |
| Hydro-Québec | Net Metering up to 50 kW | Hydro-Québec guide |
| Ontario (province) | Electricity Act, IESO rules | Ontario guide |
| British Columbia | Clean Energy Act | BC guide |
| Alberta | AESO market rules | Alberta guide |
| CSA C22.1 | Canadian Electrical Code | CSA guide |
BC Hydro: July 2026 Rule Change
BC Hydro is implementing a significant update to its Net Metering program (Rate Schedule RS 2289) in July 2026. Key changes include revised export credit rates and updated interconnection documentation requirements. Installers working in British Columbia must verify the new rules before commissioning any system after July 1, 2026. The SurgePV BC Hydro guide will be updated as the final rule text is published.
Canadian Installer Requirements
- Red Seal electrician (Interprovincial Standards Program) recognized in all provinces
- Ontario: Licensed Electrical Worker (LEW) required — separate from Red Seal
- Quebec: C license from the Régie du bâtiment du Québec (RBQ)
- Equipment must meet CSA standards; inverters typically require CSA C22.2 No. 107.1 certification
The solar design software used for Canadian projects must account for CSA C22.1 conductor sizing rules, which differ from NEC 2020 in derate factors and conduit fill calculations.
Brazil: The Americas’ Fastest-Growing Distributed Market
Brazil’s solar market is the second-largest in the Americas by installed capacity. As of year-end 2025, Brazil had 62 GW of total photovoltaic capacity in operation — 43 GW from distributed generation (systems up to 5 MW) and 19 GW from centralized utility-scale plants. The country added 7.4 GW of new capacity in 2025, with distributed solar dominating new additions.
ANEEL Resolution 1000/2021: The GD Framework
Brazil’s distributed generation framework is governed by ANEEL Resolution 1000/2021 (which superseded the original Resolution 482/2012). The framework applies to systems from micro (up to 75 kW) to mini (75 kW to 5 MW) distributed generation.
| System Type | Capacity | Credit Validity | Access Study Required? |
|---|---|---|---|
| Micro GD | Up to 75 kW | 60 months (rolling) | No |
| Mini GD | 75 kW – 5 MW | 60 months (rolling) | Yes (estudo de acesso) |
How the credit system works:
- Surplus energy exported to the grid is converted into credits (in kWh) on the customer’s account
- Credits offset future electricity consumption at the distribution tariff rate
- Credits expire after 60 months if unused — a rolling window, not a calendar year
- Credits can be shared across multiple units under the same CPF/CNPJ (shared generation / autoconsumo remoto)
ANEEL SIGR System
All DG interconnection requests in Brazil must be submitted through ANEEL’s online SIGR platform (Sistema de Informações de Geração Distribuída). The DISCOM has defined timelines to respond to connection requests — typically 30 days for micro GD and 90 days for mini GD. Delays beyond these timelines can be formally contested with ANEEL.
Brazil Equipment Requirements
- INMETRO certification required for solar panels and inverters sold in Brazil
- Panels must meet IEC 61215 and IEC 61730; inverters must meet IEC 62109
- Local DISCOM may require additional protection relays for mini GD systems
- ICMS exemption on solar equipment is available in most Brazilian states — confirm the current state Convênio ICMS status before quoting, as rules vary
Brazil State Distribution
São Paulo (5.8 GW), Minas Gerais (4.9 GW), Paraná (3.7 GW), Rio Grande do Sul (3.4 GW), and Mato Grosso (2.6 GW) hold the largest shares of distributed solar. The Northeast — Bahia, Ceará, Pernambuco — is the fastest growing region for utility-scale solar due to high irradiance levels (GHI exceeding 2,000 kWh/m²/year in the semi-arid interior).
For accurate yield simulation on Brazilian projects, use SurgePV’s solar design tool with PVGIS or NASA POWER irradiance datasets calibrated for Brazilian locations.
Mexico: Policy Uncertainty, Growing Market
Mexico has approximately 12.4 GW of installed solar capacity as of 2025, with distributed solar reaching 4.42 GW by year-end 2024. The country adds roughly 1+ GW annually across utility and distributed segments.
Regulatory Framework
Mexico’s solar regulatory environment has been in flux since 2021. Key bodies:
- CRE (Comisión Reguladora de Energía): Issues interconnection permits for generators connecting to the national grid
- CENACE (Centro Nacional de Control de Energía): National grid operator; controls dispatch and grid access
- CFE (Comisión Federal de Electricidad): State-owned utility; dominant distributor and transmission owner
The Current Interconnection Challenge
Under current administration policy (post-2021 Energy Reform amendments), private renewable energy projects face a more restrictive interconnection environment:
- New projects must align with the government’s National Energy Plan geographic zones and technology preferences
- CENACE discloses maximum interconnection capacity (without requiring grid reinforcements) in annual plans — projects outside available headroom face significant delays
- CFE’s preferential treatment in dispatch order affects the economics of private solar generation
Mexico: Verify CRE Permit Status Before Contracting
Mexico’s interconnection rules have shifted materially since 2021. Before signing an EPC contract for any C&I or utility-scale project in Mexico, confirm current CRE permit availability for the specific location and technology with a local regulatory advisor. Distributed solar under 0.5 MW for self-consumption is less affected by the policy shifts.
Mexico Distributed Solar (Self-Consumption)
Distributed solar for self-consumption (autoabasto) under 0.5 MW remains the most accessible segment for private developers. These systems:
- Connect under CFE’s distributed generation tariff
- Export under net metering provisions in the CFE service contract
- Are exempt from the national energy planning alignment requirements that affect larger projects
Mexico targets up to 9.5 GW of new solar and wind capacity by 2030, with CFE beginning construction of 6 GW of new generation capacity in 2026.
Chile: Atacama Records and an Active Net Billing Market
Chile has 11.6 GW of cumulative PV capacity as of year-end 2025, following 1.1 GW of additions in 2025. Solar now accounts for approximately 60% of Chile’s renewable capacity, and solar plus wind combined supplied nearly 38% of total electricity generation in 2025.
CNE Net Billing Scheme
Chile’s net billing framework (established under Ley 20.936 and updated by subsequent CNE resolutions) allows residential and commercial customers to install solar and export surplus at the node price (precio de nudo).
| Parameter | Value |
|---|---|
| Maximum system size | 300 kW |
| Compensation rate | Node price (precio de nudo) — typically 30–50% of retail |
| Credit settlement | Monthly billing cycle |
| Eligibility | Residential, commercial, industrial (up to 300 kW) |
| Regulator | CNE — Comisión Nacional de Energía |
| Installer requirement | CNE-registered installer |
By July 2025, Chile’s net billing market had reached 383 MW across 33,247 installations, with the Metropolitan Region (Santiago) accounting for roughly 30% of installed capacity.
Atacama Desert: World-Record LCOE
The Atacama Desert in northern Chile holds some of the world’s highest direct normal irradiance (DNI) values — making it the location of record-low solar LCOE bids globally. Utility-scale projects in the Atacama have achieved LCOE below $0.02/kWh in competitive auctions. The CNE administers Chile’s energy auction process (licitaciones de energía) for utility-scale projects.
Colombia: Ley 1715 Tax Benefits
Colombia’s solar market is growing from a smaller base. The primary incentive framework is Ley 1715 of 2014 (updated by Ley 2099 of 2021 — the Energy Transition Law), administered by UPME (Unidad de Planeación Minero Energética).
Ley 1715 Tax Incentives
| Incentive | Detail |
|---|---|
| Income tax deduction | 50% of total investment, deductible over up to 15 years (max 50% of taxable income/year) |
| Accelerated depreciation | Assets depreciated over 5 years instead of standard schedules |
| VAT exclusion | Solar equipment and services excluded from 19% VAT |
| Import duty exemption | Equipment not locally manufactured exempt from import tariffs |
| Net metering | Available under CREG Resolution 030/2018 |
UPME Resolution 135 of 2025 updated the procedures and fees for applying for Ley 1715 tax incentive certificates. Applications are processed in cycles — confirm the current cycle’s open dates before submitting.
Colombia’s long-term energy plan projects between 7.4 and 11.4 GW of solar by 2037, from an estimated current base of 1–2 GW.
Colombia: Apply for the UPME Certificate Early
The Ley 1715 income tax deduction requires a UPME-issued certificate before the project is commissioned. Applications are processed in scheduled cycles, and cycles can close quickly. File the application during the early project development phase — not after construction begins.
Argentina: Growing Despite Economic Headwinds
Argentina’s solar market continues to expand despite significant economic volatility, currency controls, and import restrictions on solar equipment. The national grid is operated by CAMMESA (Compañía Administradora del Mercado Mayorista Eléctrico).
Key frameworks:
- Ley 27.424 (2017): Distributed generation framework allowing self-generation and surplus export for residential and commercial users
- RENOBAR and RENOVAR programs: Government renewable energy tender programs for utility-scale projects (activity has been limited in recent years)
- Provincial rules vary significantly — Buenos Aires, Mendoza, and Córdoba have the most developed distributed solar frameworks
Currency restrictions and import duties on solar equipment add project cost uncertainty. Local sourcing of balance-of-system components is increasingly common. Solar installers working in Argentina should verify current AFIP (tax authority) treatment of equipment imports before quoting.
Peru: Rural Electrification and Growing Urban Solar
Peru’s solar market is regulated by OSINERGMIN (Organismo Supervisor de la Inversión en Energía y Minería). The country has a strong rural electrification focus, with off-grid solar home systems (SHS) and mini-grids serving communities in the Andes and Amazon regions where grid extension is not economically viable.
Key frameworks:
- Decreto Legislativo 1002 (2008): Promotes renewable energy in the national grid
- RER auctions: Renewable energy auctions have brought several hundred MW of solar to the national grid (SIN — Sistema Interconectado Nacional)
- DRE (Distributed Renewable Energy): MINEM programs for rural off-grid electrification using solar
Urban and commercial grid-tied solar in Lima and other major cities is growing. Interconnection to the national grid requires OSINERGMIN approval and compliance with COES-SINAC (grid operator) technical standards.

Common Americas Compliance Pitfalls
| Mistake | Country | Impact | Correct Approach |
|---|---|---|---|
| Quoting residential ITC as still available | USA | Customer financial model 30% off | Residential Section 25D expired Dec 31, 2025; commercial Section 48E still active |
| Ignoring NEM 3.0 export rates in California | USA | Project under-performs vs pro forma | Model time-of-use export rates ($0.02–0.05/kWh), not retail offset |
| Missing BC Hydro July 2026 RS 2289 changes | Canada | Interconnection rejection | Verify updated rules before commissioning any BC project after July 1, 2026 |
| Submitting mini GD access request without estudo de acesso | Brazil | DISCOM rejection; project delays | Systems above 75 kW need a formal access study filed with DISCOM |
| Applying for ANEEL credits on uncertified inverters | Brazil | Equipment rejected at inspection | Only INMETRO-certified equipment qualifies for GD framework credits |
| Signing Mexico EPC before CRE permit confirmed | Mexico | Stranded project; no grid access | Verify CRE permit availability for specific location before contracting |
| Missing UPME certificate deadline in Colombia | Colombia | Ley 1715 tax benefit forfeited | Apply during project development phase — UPME cycles close quickly |
| Treating all Canadian provinces as identical | Canada | Incorrect export rate modeling | Each utility has separate rules; BC Hydro, Hydro One, and Hydro-Québec differ substantially |
How to Use the SurgePV Americas Compliance Hub
The solar compliance hub covers four continents. For the Americas specifically:
Step 1: Go to your country’s compliance hub
Identify the applicable national and state/province framework
Confirm your project country, state/province, and serving utility. For the USA, go to /solar-compliance/usa/ and navigate to your state guide. For Canada, start at /solar-compliance/canada/ and select your utility.
Check installer certification requirements
USA requires NABCEP or state electrical licence. Canada requires Red Seal or provincial licence (LEW in Ontario, RBQ C licence in Quebec). Brazil requires DISCOM installer registration and INMETRO-certified equipment. Chile requires CNE-registered installer status for net billing eligibility.
Verify current export scheme and compensation rates
Export rates change. California’s NEM 3.0 dropped export compensation by roughly 85% versus NEM 2.0. BC Hydro’s RS 2289 rules change in July 2026. Brazil’s GD credits remain at full distribution tariff rate. Always pull the current tariff from the utility or regulator before finalizing a financial model.
Submit interconnection application before installation
USA: file with the serving utility before installation — timelines range from 30 to 180 days. Brazil: file solicitação de acesso via ANEEL’s SIGR system; micro GD systems get a 30-day response window, mini GD 90 days. Canada: BC Hydro and Hydro One require pre-installation application submission.
Claim available tax incentives before the filing deadline
USA commercial ITC (30%) is claimed on IRS Form 3468 in the tax year the system is placed in service. Colombia’s Ley 1715 deduction requires a UPME certificate filed before commissioning. Brazil’s ICMS exemption requires the correct fiscal classification (NCM code) on procurement invoices — retroactive correction is difficult.
Frequently Asked Questions
What is the USA’s current solar ITC rate?
The federal Investment Tax Credit (ITC) for commercial solar is 30% base rate under the Inflation Reduction Act (Section 48E). With domestic content, energy community, and low-income adders, effective rates can reach 40–50%. The residential ITC (Section 25D, for homeowners) expired December 31, 2025. Commercial and utility ITC remains in force through 2032.
How does Brazil’s net metering (GD) framework work?
Brazil’s distributed generation (GD) framework under ANEEL Resolution 1000/2021 allows systems up to 5 MW to export surplus energy and receive credits valid for 60 months on a rolling basis. The scheme covers residential, commercial, and rural systems. Systems above 75 kW require a formal access study (estudo de acesso) from the local DISCOM. Credits are valued at the full distribution tariff rate — making Brazil’s system more financially attractive than Chile’s node-price net billing.
What is California NEM 3.0 and how does it affect solar ROI?
California’s NEM 3.0 (effective April 15, 2023) replaced 1:1 retail-rate net metering with market-based export compensation averaging $0.02–0.05/kWh, versus retail rates of $0.25–0.35/kWh. New California solar projects commissioned under NEM 3.0 typically require paired battery storage to maintain financial viability. Systems that received permission to operate (PTO) under NEM 2.0 retain that tariff for 20 years.
Does Canada have a national solar net metering policy?
No. Solar net metering in Canada is utility-specific and province-specific. BC Hydro, Hydro One (Ontario), and Hydro-Québec each have separate programs with different capacity caps, export rates, and application processes. The federal government provides a 30% Clean Technology Investment Tax Credit, but program rules for grid export are set by each utility. SurgePV has 9 dedicated Canada compliance guides at /solar-compliance/canada/.
What are Chile’s solar net billing rules?
Chile’s net billing scheme under Ley 20.936 allows residential and commercial systems up to 300 kW to sell surplus energy at the node price (precio de nudo), typically 30–50% of retail rates. The CNE (Comisión Nacional de Energía) administers the framework. By mid-2025, the scheme covered 33,247 installations totaling 383 MW across Chile. The Atacama Desert in northern Chile hosts utility-scale projects with some of the world’s lowest recorded solar LCOE figures.
