Ley 57-07 incentives: Solar panel imports, inverters, and related equipment are 100% customs and ITBIS tax-free under Dominican Ley 57-07 (Ley sobre Incentivo al Desarrollo de las Fuentes Renovables de Energía). This is a significant saving of approximately 25% versus non-exempt equipment. Verify that your installer uses the proper customs codes when importing.

How to Use This Calculator

Enter your monthly bill and province

Enter your average monthly electricity bill in Dominican pesos (DOP/RD$) from your distribution utility — EdeEste serves the eastern region including Punta Cana, La Romana, and San Pedro de Macorís; EdeNorte covers the north including Santiago and Puerto Plata; EdeSur serves Santo Domingo and the south. Dominican electricity rates are among the highest in the Caribbean at DOP 8–15/kWh (approximately $0.13–0.25/kWh), which — combined with excellent solar radiation of 5.4–5.7 PSH — creates some of Latin America's fastest solar paybacks of 3–5 years.

Medición neta (net metering)

The Dominican Republic's medición neta program, established under Ley 57-07 (Ley General de Electricidad) and implemented via SIE (Superintendencia de Electricidad) Resolution SIE-057-2012, allows solar system owners to export surplus electricity to the grid at 100% retail credit — a genuine 1:1 net metering arrangement. All three distribution utilities (EdeEste, EdeNorte, EdeSur) are legally required to accept medición neta connections and credit accounts monthly.

Ley 57-07 tax and customs incentives

This is where the Dominican Republic stands out: Ley 57-07 makes solar equipment imports entirely customs and ITBIS (IVA equivalent) tax-free. Solar panels, inverters, mounting systems, batteries, and associated equipment can be imported duty-free when properly classified. This represents approximately 25% in savings on equipment costs — making DR one of the most solar-incentivized jurisdictions in the Caribbean. Ensure your installer uses the correct customs tariff codes when importing equipment.

The Formula

Monthly kWh = Monthly Bill ÷ RD$12/kWh (blended retail rate) Annual production = kWp × PSH × 365 × 0.80 efficiency Self-consumption = Annual kWh × 40% (medición neta) or 60% (self-consumption) Self-consumption savings = Self-consumed kWh × RD$12/kWh Medición neta credit = Exported kWh × RD$12/kWh (1:1 retail) Ley 57-07 saving = System cost × ~25% (customs + ITBIS exemption) System cost = kWp × RD$60,000–90,000/kWp (tax-free imports) Payback = Total cost ÷ Annual benefit (typically 3–5 years)

The Dominican Republic has excellent solar resources across the entire country — 5.4–5.7 PSH depending on province, with Punta Cana and La Altagracia (5.7 PSH) consistently the sunniest. The combination of high electricity rates, outstanding solar radiation, 1:1 net metering, and Ley 57-07 tax exemptions creates one of the most compelling solar investment environments in the entire Caribbean basin. SIE (Superintendencia de Electricidad) regulates the sector; CNE (Comisión Nacional de Energía) sets policy.

Example

Juan — Santo Domingo home, 5kWp medición neta

Juan pays RD$8,000/month for his family home in Santo Domingo. He installs a 5kWp system with EdeSur medición neta, importing equipment tax-free under Ley 57-07.

Monthly billRD$8,000
Province / PSHSanto Domingo, 5.5 PSH
System size5 kWp
UtilityEdeSur
Net meteringYes — medición neta

Result

Monthly kWh usage~667 kWh/mo
Annual production~8,030 kWh/yr
Production per kWp~1,606 kWh/kWp/yr
Self-consumption savingsRD$~38,500/yr
Net metering creditRD$~58,000/yr
Total annual benefitRD$~96,500/yr
Ley 57-07 savingRD$~93,750 saved
System cost (tax-free)RD$300,000–450,000
USD equivalent~$5,000–$7,500
Payback~3.1–4.7 years
25-year net savingsRD$~2,037,500

Santo Domingo's 5.5 PSH produces ~1,606 kWh/kWp/yr — excellent productivity. At RD$8,000/month bill with 1:1 net metering and Ley 57-07 tax-free imports, Juan's payback is 3–5 years — among the fastest in Latin America. The 25-year net savings of over RD$2 million is transformative for a Dominican family. Punta Cana (5.7 PSH) would produce even faster payback.

FAQ

Absolutely yes — the Dominican Republic offers one of the best solar ROI environments in the entire Caribbean and Latin America. High electricity rates (DOP 8–15/kWh), excellent solar resources (5.4–5.7 PSH), 1:1 medición neta, and Ley 57-07 customs/tax exemptions combine to deliver payback periods of 3–5 years for residential systems. Hotels and commercial properties in Punta Cana can achieve payback even faster given larger systems and high commercial tariffs. Frequent power outages (apagones) also make solar + battery storage a quality-of-life priority.
Medición neta is established by Ley 57-07 (2007) and SIE Resolution SIE-057-2012. Your solar system connects to the grid through a bidirectional meter installed by your distribution utility (EdeEste, EdeNorte, or EdeSur). Surplus electricity produced beyond your consumption is exported and credited to your account at the full retail rate — a genuine 1:1 arrangement. Credits accumulate monthly. Your solar installer must submit the connection application to your utility, which typically takes 2–4 months to process. SIE (Superintendencia de Electricidad) oversees compliance and disputes.
Ley 57-07 (Ley sobre Incentivo al Desarrollo de las Fuentes Renovables de Energía y de sus Regímenes Especiales) is the Dominican Republic's flagship renewable energy law. For solar, its key incentives are: (1) Complete customs duty exemption on imported solar equipment — panels, inverters, batteries, mounting, and cables; (2) Complete ITBIS (Dominican equivalent of VAT, currently 18%) exemption on solar equipment purchases; (3) Income tax exemption on income from electricity sales under net metering for 10 years; (4) Property tax exemption for solar installations. Combined, these represent roughly 25–30% savings versus non-exempt equipment.
The utility is determined by your location — you cannot choose. EdeEste (East) serves the eastern region including Punta Cana, La Romana, San Pedro de Macorís, and La Altagracia. EdeNorte (North) serves Santiago, Puerto Plata, and the Cibao region. EdeSur (South/West) serves Santo Domingo, San Cristóbal, and most southern provinces. All three are legally required under Ley 57-07 and SIE resolutions to accept medición neta applications and credit surplus solar at retail rates. EdeEste is generally considered the most efficient for net metering applications due to the high concentration of solar projects in the tourism zones it serves.
Punta Cana / La Altagracia (5.7 PSH) and La Romana (5.6 PSH) are the sunniest — the eastern tip of the island sits in the dry rain shadow of the central mountains and benefits from the Caribbean trade winds removing cloud cover. Santo Domingo (5.5 PSH) and San Pedro de Macorís (5.5 PSH) are also excellent. Santiago (5.4 PSH) and Puerto Plata (5.4 PSH) on the north coast are slightly less sunny but still very strong. The entire Dominican Republic is within 2°N–20°N latitude — all provinces have outstanding solar resources by global standards.
