Real project: an off-grid system, rebuilt for winter. ❄️
This 12-year-old off-grid system in Eastern Ontario had lead-acid batteries, limited storage and an under-sized solar array, and winter is when that hurts most.
Here's what our team did:
• Replaced the older 235 W panels with 500 W LONGi panels, more than doubling the solar capacity
• Added vertical panels, switched on in late fall to use the lower sun and the light reflected off snow
• Swapped lead-acid for Discover Helios lithium batteries, doubling the storage
• Had our licensed electrician connect the inverter, generator and battery system
The result: better reliability in every season and less time on the generator.
