Common Questions and Concerns
Addressing the most frequent questions about solar TRU adoption helps fleet operators make informed decisions. Get personalized answers with our free consultation call.
Will solar TRUs work in cloudy regions
Yes. Modern solar TRUs incorporate large battery banks that provide 24-48 hours of autonomous operation. Even in consistently cloudy regions, the combination of daily solar generation and overnight grid charging ensures reliable operation. Systems in Northern Europe have demonstrated 99.5% uptime year-round.
What about extreme temperature requirements
Solar TRUs maintain temperatures from -25°C to +30°C reliably. The electric compressors actually perform more efficiently than diesel units in extreme conditions. For ultra-low temperature applications like ice cream (-30°C), specialized systems with larger battery banks are available.
How long do the batteries last
Current lithium-ion batteries are warrantied for 8-10 years or 4,000 cycles. Real-world data shows 80% capacity retention after 10 years. Battery replacement costs are included in TCO calculations and still result in significant lifetime savings versus diesel.
