Solar Irradiation Data in Guatemala

Guatemala enjoys high solar potential throughout much of the country, with especially favorable conditions in the dry season.

Key Solar Irradiation Data:

Annual Solar Irradiation: Typically ranges from 4.5 to 5.5 kWh/m²/day
High Irradiation Regions: The southern and western parts of the country, including areas like Escuintla, Retalhuleu, and San Marcos, experience the highest solar exposure
Peak Irradiation: Reaching 5.5–6.0 kWh/m²/day during the dry season (November to April), especially in lowland and coastal regions

This level of solar radiation offers a strong foundation for both residential and large-scale solar energy projects.

Temperature Factors in Guatemala

Average Annual Temperature: Ranges from 19°C to 28°C (66°F to 82°F) depending on the region and altitude
Impact on Solar Panels: Guatemala’s moderate temperatures are ideal for maintaining solar panel efficiency year-round, with performance likely to improve in cooler highland areas

Recommendation: Use high-efficiency monocrystalline solar panels, which are well-suited for tropical conditions and perform well in moderate temperature climates.

Energy Demand and Grid Situation in Guatemala

National Energy Demand: Guatemala’s energy demand is driven by residential needs, agriculture, and industry, particularly in urban areas like Guatemala City
Electricity Source: The country has a relatively diversified energy matrix, with hydropower playing a significant role. However, solar is increasingly seen as a valuable renewable energy source to reduce reliance on fossil fuels
Electricity Costs: Electricity prices in Guatemala are moderate, but the adoption of solar can significantly reduce costs for both homes and businesses
Grid Infrastructure: Guatemala has a reliable national grid, but solar energy solutions, including microgrids and off-grid systems, are particularly beneficial for rural areas and communities with limited or no access to the grid

Preferred System Type in Guatemala

National Energy Demand: Guatemala’s energy demand is driven by residential needs, agriculture, and industry, particularly in urban areas like Guatemala City
Electricity Source: The country has a relatively diversified energy matrix, with hydropower playing a significant role. However, solar is increasingly seen as a valuable renewable energy source to reduce reliance on fossil fuels
Electricity Costs: Electricity prices in Guatemala are moderate, but the adoption of solar can significantly reduce costs for both homes and businesses
Grid Infrastructure: Guatemala has a reliable national grid, but solar energy solutions, including microgrids and off-grid systems, are particularly beneficial for rural areas and communities with limited or no access to the grid

Dust and Sand Factor in Guatemala

Dust Impact: Low dust accumulation due to frequent rainfall during the wet season (May to October) and humid climate

Recommendation: Occasional cleaning may be necessary, especially in the dry season, but overall, dust does not significantly affect solar performance

Humidity and Rainfall (Humidity Factor) in Guatemala

Humidity Levels: High, typically around 70–80% year-round
Rainfall: Guatemala experiences a rainy season from May to October, with heavy showers and tropical storms
Impact on Solar Panels: High humidity and rainfall during the wet season can lead to moisture-related issues if not properly sealed

Recommendation: Use weather-sealed, corrosion-resistant materials and IP-rated enclosures to protect against moisture and rainwater exposure.

Ocean (Salt Corrosion Factor) in Guatemala

Saltwater Corrosion: Although Guatemala has no direct ocean exposure, the country’s proximity to the Pacific Ocean makes coastal areas more vulnerable to salt-laden air

Recommendation: Use marine-grade materials, stainless steel fasteners, and coated wiring for systems installed in coastal regions to avoid corrosion from salt exposure

Government Policies and Solar Incentives in Guatemala

Guatemala is making strides toward renewable energy integration:

Renewable Energy Goals: The government has committed to increasing the share of renewable energy in the national grid, with solar energy expected to play an increasingly important role
Incentives for Solar: Guatemala offers tax exemptions and subsidies for solar installations, as well as import duty exemptions on solar equipment
Net Metering: Guatemala supports net metering, allowing consumers with solar systems to sell excess electricity back to the grid
International Support: Guatemala receives support from international organizations such as IDB and IRENA, aiming to scale up the deployment of solar energy and reduce greenhouse gas emissions

ROI on Solar Systems in Guatemala

ROI Period: Solar systems in Guatemala typically achieve payback within 5 to 7 years, aided by government incentives, high solar potential, and reduced energy costs
Savings Potential: Solar users can expect to reduce electricity bills by 50–70%, particularly when battery storage is incorporated to maximize energy savings

Conclusion on Solar Power in Guatemala
