About solar in Tlaquepaque
Tlaquepaque, Mexico has a temperate climate with meaningful seasonal variation in solar resource. Its annual peak sun hours average 5.9 kWh/m²/day, a excellent solar resource by global standards.
The strongest month in Tlaquepaque is April (spring) at 7.45 kWh/m²/day, and the weakest is December (winter) at 4.61 kWh/m²/day. When sizing a year-round off-grid system, it's standard practice to design against the December value rather than the annual average — otherwise the battery bank runs low during the darkest weeks.
Tlaquepaque's solar conditions are well within the range where off-grid PV is a straightforward engineering exercise with standard-sized arrays and lithium batteries.
FAQ
- What are the peak sun hours in Tlaquepaque?
- Tlaquepaque averages 5.9 peak sun hours per day annually, ranging from 4.61 in December to 7.45 in April.
- How many solar panels do I need in Tlaquepaque?
- Panel count depends on your daily load. At Tlaquepaque's annual average of 5.9 kWh/m²/day, a 5 kWh/day load needs roughly 3 × 400 W panels. Use the calculator above for your actual load.
- What size battery do I need in Tlaquepaque?
- Sizing against Tlaquepaque's worst month (December, 4.61 kWh/m²/day) with 2 days of autonomy at 80% depth of discharge, a 5 kWh/day load needs about a 12.5 kWh battery bank.
- How does Tlaquepaque's solar resource compare globally?
- Tlaquepaque sits in solar zone 4 out of 5 (where 5 is strongest) at 5.9 kWh/m²/day — excellent by global standards. For reference, top-tier desert sites average ~6.5 and high-latitude cities around 2.5 kWh/m²/day.
- How much does winter reduce solar output in Tlaquepaque?
- Tlaquepaque's worst month (December) delivers 4.61 kWh/m²/day — about 62% of the summer peak of 7.45. Off-grid systems here typically oversize 1.5–2× or pair with a backup source.
- Do cloudy days significantly affect Tlaquepaque's solar?
- Partly. Diffuse light still produces 10–25% of clear-sky output. Tlaquepaque's 5.9 kWh/m²/day already reflects average cloudiness, so no further derating is needed for sizing.
- What panel tilt works best in Tlaquepaque?
- At Tlaquepaque's latitude (21°), a fixed tilt near 21° balances year-round yield. Winter-heavy loads favor latitude + 15°; summer-heavy, latitude − 15°.
