Ontario, Canada. A family of 4 with average monthly consumption of 900kWh wanted to cut electricity bills and add backup power during winter outages. Here is the complete system we designed, installed, and have been monitoring for 18 months.
Project Overview
The homeowners had two goals: reduce monthly electricity bills and ensure backup power during Ontario's frequent winter ice storms. The property had an unshaded south-facing roof with 60m2 of usable space.

18-Month Performance Data
Based on HOMESOL app monitoring and utility bills:
Monthly Production (kWh)
- January (winter)680 kWh - 620 self-consumed - 60 exported
- April (spring)1,280 kWh - 900 self-consumed - 380 exported
- July (summer)1,580 kWh - 950 self-consumed - 630 exported
- October (autumn)1,100 kWh - 850 self-consumed - 250 exported
- Annual Average1,180 kWh - 850 self-consumed - 330 exported

Performance Highlights
- Self-consumption rate72% (high for grid-tied)
- Net metering valueExported energy credited at retail rate
- Backup duration36 hours during winter outage
- Bifacial panel gain+12% vs standard mono panels
- Battery backup valueAvoided outages (3+ days/year)
"The backup battery saved us twice during ice storms last winter. We had heat, hot water, and internet while neighbors were in the dark for 3 days. The HOMESOL monitoring app is also very intuitive - I can check production from my phone anywhere."

Key Takeaways for Buyers
- Battery backup is worth it in areas with grid instability. The peace of mind alone justifies the cost premium.
- Oversize the system 20% - energy needs grow (EV charging, new appliances). This system was designed for 10kW but accommodates expansion to 15kW.
- Bifacial panels delivered 12% more energy than standard mono panels in this installation.
- Professional installation is non-negotiable for grid-tied systems. DIY risks voiding warranties and grid interconnection approval.
