Start here. Everything you need to plan, size, and build your first off-grid solar system the right way.
Battery voltage on a LiFePO4 bank is the most misread number in off-grid solar. A homeowner on Silvercreek Parkway in Guelph, Wellington County installed a 200Ah LFP battery bank in the summer of 2024. He connected his charge controller display and used the voltage reading as his state-of-charge reference throughout the fall, the same way
Low light solar is not zero solar, it is reduced solar, and the difference between harvesting it and missing it entirely comes down to two wiring decisions. A homeowner on Stone Road West in Guelph, Wellington County ran four 100W panels in parallel for two years on a 24V battery system. He noticed that on

The ability to track the sun is the single biggest performance variable on any Ontario solar installation that is not at a fixed tilt. A homeowner on Watson Parkway North in Guelph, Wellington County installed a linear actuator single-axis tracking system on his 1,200W ground mount in the spring of 2024. The system cost approximately

Solar battery lifespan is measured in cycles, not years, and that single distinction changes every buying decision. A homeowner on Edinburgh Road South in Guelph, Wellington County installed a 100Ah LFP battery bank in the spring of 2023. He read the spec sheet, saw 3,000 cycles at 80% depth of discharge, and assumed he had
The time to test solar panel output is before the first bolt goes into the roof, not after. A homeowner on Kortright Road West in Guelph, Wellington County unboxed four 200W Renogy panels in the spring of 2025. He set them flat on the driveway in the afternoon sun before carrying any of them up

Solar panel degradation is not a cliff edge, it is a gentle slope that the best panels in Ontario barely even notice. A homeowner on Clair Road East in Guelph, Wellington County installed a 1,200W array in the spring of 2015. In the fall of 2025, ten years later, he noticed his battery bank was
Flexible solar panels are not cheap rigid panels, they are a different product for a different job. In Rockwood, Wellington County a van-lifer converted her high-roof Transit in the spring of 2024. She installed two Renogy 100W ETFE flexible panels on the curved fibreglass roof cap using silicone adhesive and nothing else, flat against the
The lifepo4 vs agm decision comes down to one number: cost per cycle. In April 2025 a retired electrician on Kortright Road West in Guelph, Wellington County switched from his third set of AGM batteries to a single Battle Born 100Ah LiFePO4. He had built a 400W workshop solar array in 2019 with two 100Ah

The charge tesla solar question is not about whether it works, it is about whether the math works for your commute. In January 2025 a homeowner on Kortright Road West in Guelph, Wellington County asked if his planned 2.4 kW solar array could cover his Model 3 RWD charging for his 60 km daily commute
Every rv solar panels question I get from Ontario RVers comes down to one fear: that the panels are going to fly off at 110 km/h on the 401. This concern is valid but the solution is straightforward. In June 2025 a couple on Kortright Road West in Guelph, Wellington County prepared their Class C
