Is solar worth it in Cambridge?

Yes, solar is a strong investment in Cambridge. With 2,066 sun hours per year, average electricity bills of $176/month, and provincial rebates, most systems pay for themselves within 10 years, then provide free electricity for 15+ more years.

Do solar panels work in Cambridge during winter?

Yes, solar panels work year-round in Cambridge. While winter days are shorter, panels actually operate more efficiently in cold temperatures. Snow typically slides off south-facing panels within a day. Annual production estimates for Cambridge already account for seasonal variation, with summer months producing 2-3x more than winter.

How long does solar installation take in Cambridge?

The physical installation usually takes 1 to 3 days. The full project also needs a building permit where required, an electrical inspection, and connection approval from Cambridge and North Dumfries Hydro. Timelines depend on those permits and approvals, so no completion date should be promised until they are complete.
