Overview
- New reporting details falling system prices, average bill cuts of 50–70% that vary with system size and batteries, and paybacks of about 4–6 years in Spain and 5–8 across Latin America, reaching up to 10 years where incentives are limited.
- Mexico’s rooftop solar penetration sits at 0.8% of homes, according to INEGI, as long-standing power subsidies leave most families paying below the real cost of electricity.
- Experts say the math works best for high-use households on the DAC tariff who pay more than 2,000 pesos every two months, as well as for small businesses and industry.
- Typical price ranges span $4,000–$8,000 for basic home systems worldwide and $9,000–$18,000 with batteries, while Mexican quotes run about 22,000–50,000 pesos for homes and 80,000 pesos or more for businesses.
- A Mexican case for a 1,300 kWh bimonthly user shows bills dropping to the fixed fee, a 145,847‑peso outlay recovered in about 4.8 years, and savings above 600,000 pesos over roughly 25 years.
