⭐⭐⭐⭐⭐ James Carter - Rural Homesteader
"We’ve been completely off-grid since installing the PNG Solar OFF GRID 18KW system last fall. The monocrystalline panels perform exceptionally well, even during shorter winter days. We run a well pump, refrigerator, HVAC, and multiple electronics without any hiccups. The MPPT controller makes a noticeable difference in energy harvest compared to our old PWM setup. Lithium-ion battery option was worth every penny—no maintenance and consistent performance."Purchase Date: October 2024 | Usage Period: 6 months
⭐⭐⭐⭐⭐ Maria Gonzalez - Organic Farm Operator
"Powering our irrigation system, chicken coop, and farmhouse was a challenge until we upgraded to the Pro Model (18kW). The ground-mount flexibility allowed us to install on uneven terrain, and the system handles our peak loads effortlessly. I especially appreciate the real-time monitoring via the smart control panel—it alerts me if anything’s off. After five months, we’ve had zero downtime. This is industrial-grade reliability at a reasonable price."Purchase Date: February 2025 | Usage Period: 4 months
⭐⭐⭐⭐☆ David Park - Remote Workshop Owner
"I run a metal fabrication shop 20 miles from the nearest power line. The 18KW system keeps my welding machines, air compressors, and lighting running smoothly. We chose the lithium-ion configuration for longevity, and it’s already paid for itself in avoided generator fuel costs. Installation was straightforward thanks to pre-wired components, though I recommend hiring a certified technician for final setup. Only reason I’m not giving five stars is the initial cost—it’s steep, but justified by performance."Purchase Date: June 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Emily Tran - Mountain Cabin Owner
"Our off-grid cabin now feels like home. The 18KW system powers heating, lighting, and even a small washer—something we never thought possible without a generator. We get frequent snow cover, but the high-efficiency panels still generate enough power thanks to the MPPT controller. The UL and IEC certifications gave us confidence in safety, especially with family visiting. After seven months, the battery shows no degradation. Truly peace of mind in a box."Purchase Date: November 2024 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Raj Patel - Telecommunications Site Manager
"We deployed the PNG Solar 18KW system at a remote cell tower site with no grid access. It powers communication equipment 24/7, including backup systems during outages. The modular design allowed us to scale from 12kW to 18kW as load demands increased. Lithium-ion batteries have held up perfectly across temperature extremes—from -10°C to 40°C. With the 5-year warranty and remote monitoring, we’ve reduced maintenance visits by 60%. A game-changer for off-grid infrastructure."Purchase Date: April 2025 | Usage Period: 2 months
