About solar in Consolación del Sur

Consolación del Sur, Cuba has a warm, tropical climate with a distinct wet and dry season. Its annual peak sun hours average 5.25 kWh/m²/day, a excellent solar resource by global standards.

The strongest month in Consolación del Sur is April (spring) at 6.46 kWh/m²/day, and the weakest is December (winter) at 3.85 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.

Consolación del Sur'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 Consolación del Sur?
Consolación del Sur averages 5.25 peak sun hours per day annually, ranging from 3.85 in December to 6.46 in April.
How many solar panels do I need in Consolación del Sur?
Panel count depends on your daily load. At Consolación del Sur's annual average of 5.25 kWh/m²/day, a 5 kWh/day load needs roughly 4 × 400 W panels. Use the calculator above for your actual load.
What size battery do I need in Consolación del Sur?
Sizing against Consolación del Sur's worst month (December, 3.85 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 Consolación del Sur's solar resource compare globally?
Consolación del Sur sits in solar zone 4 out of 5 (where 5 is strongest) at 5.25 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 does the wet season affect solar generation in Consolación del Sur?
Consolación del Sur's dry-season output peaks at 6.46 kWh/m²/day in April; the wet season drops it to 3.85 in December. That ~50% swing is a key sizing consideration.
Can solar panels survive tropical storms in Consolación del Sur?
Most tier-1 PV panels are rated for 140+ mph wind loads; mounting hardware usually fails first. In cyclone-prone regions like Cuba, specify IEC 61215-certified panels and anchor-bolt mounts rather than ballasted.
What's the dry-to-wet output gap in Consolación del Sur?
Consolación del Sur swings from 6.46 kWh/m²/day in April (dry) to 3.85 in December (wet) — roughly 50%. Year-round off-grid systems must size against the wet-season minimum.
