Around 0.5% of Mexican homes currently host a PV installation, according to demographic data from Mexico’s National Institute for Statistics and Geography (INEGI). INEGI’s 2015 inter-census survey shows 159,745 of the nation’s nearly 32 million homes recorded in its statistics are equipped with PV systems.
Although INEGI does not give information on the capacity of these installations, the National Solar Energy Association (ANES) estimates that from 8,000 to 10,000 residential installations joined the net metering program this year, adding more than 20 MW of capacity. At the end of 2014 the Energy Regulatory Commission (CRE) reported 58.2 MW of solar PV in the net metering program.
Of the 31 states and the Federal District (Mexico City) which comprise the Mexican Republic, Baja California Sur (more than 70,000 residents and nearly 210,000 homes) and Durango (1.7 million residents and 460,000 homes) had the highest penetration of solar PV in the residential segment, with 2.1% of homes hosting solar PV systems.
Next in the ranking are the states of Chihuahua, Campeche and Nayarit. With a population estimated at 3.5 million, INEGI estimates that nearly 1,500 Chihuahuan homes host PV systems, or 1.4%. Campeche (around 900,000 residents) reported 1.1% of homes with PV systems and the same percent of residences in Nayarit (1.8 million inhabitants) host solar arrays.
Mexico City, the capital of the nation and the entity with the greatest population (8.9 million residents), came in at the middle with 0.5% of solar homes. Four other states came in above the national average. With 7.8 million residents, 0.7% of the 2 million residences registered in Jalisco reported a solar installation.
On the other end of the list is the state of Puebla (around 6.2 million residents), where only 0.2% of the 1,550,000 homes reported solar PV systems.
Yucatán (nearly 2.1 million residents) represented the second worst ranking in Mexican residential PV, with only 0.3%.
More than 450,000 residential electricity customers in Mexico are assigned the DAC rate for high consumption, which applies to homes which use more than 3,000 kilowatt-hours annually and do not receive state subsidies in the price per kilowatt-hour. ANES highlights the enormous potential of solar for these users.
