Frequently Asked Questions

When choosing between Lithium Ion (LiFePO4) and AGM batteries for your solar system, several factors come into play. Lithium batteries offer significant advantages including:

• Longer lifespan: LiFePO4 batteries can last 10+ years compared to 3-5 years for AGM
• Higher depth of discharge: You can use up to 80-90% of capacity vs 50% for AGM
• Better efficiency: Lower self-discharge rates and higher charge/discharge efficiency
• Lighter weight: Significantly lighter than AGM batteries of equivalent capacity
• Better performance: Maintains voltage better under load and in various temperatures

While AGM batteries have a lower upfront cost, lithium batteries offer better long-term value due to their superior performance and longevity.

Choosing the right solar charge controller is crucial for optimal system performance. There are two main types:

Our Recommendation: For most installations, especially in Zambia's climate, MPPT controllers provide the best performance and value. They maximize energy harvest from your solar panels, especially during the cooler morning hours and cloudy conditions.

Zambia enjoys excellent solar resources with an average of 6-7 peak sun hours per day. A typical solar panel installation can generate:

• A 100W panel produces approximately 400-500Wh per day
• A 300W panel produces approximately 1.5-2kWh per day
• A 5kW system can generate 25-30kWh per day

Actual production varies based on panel orientation, shading, temperature, and seasonal variations. We provide detailed site assessments to estimate your specific system's potential output.

Solar systems are generally low-maintenance, but regular care ensures optimal performance:

• Panel cleaning: Clean panels every 2-3 months or after dust storms
• Visual inspections: Check for physical damage, loose connections quarterly
• Battery maintenance: Monitor battery health and connections monthly
• System monitoring: Check inverter displays and remote monitoring systems regularly
• Professional service: Annual professional inspection recommended

We offer maintenance packages to keep your system running at peak efficiency. Contact us for more information about our service plans.

The payback period depends on several factors including system size, electricity costs, and usage patterns. Generally:

• Grid-tied systems: 5-8 years typical payback
• Off-grid systems: Immediate savings by avoiding grid connection costs
• Backup systems: Value includes energy security during outages

With rising electricity costs and improving technology, solar systems offer excellent long-term value. After payback, you essentially get free electricity for 20+ years as solar panels typically have 25-30 year warranties.
