Frequently Asked Questions
1. What are the benefits of installing solar panels in Calgary?
Solar panels in Calgary can significantly reduce your electricity bills, increase your home’s resale value, and lower your carbon footprint. Alberta’s abundant sunshine and net-metering policy make solar a cost-effective, eco-friendly choice.
2. How much does a typical residential solar system cost in Alberta?
A 6 kW system (about 15–20 panels) typically costs $15,000–$20,000 before rebates and incentives. After the Canada Greener Homes Loan (interest-free up to $40,000) and municipal rebates (up to $750/kW), most homeowners see net costs between $5,000–$10,000.
3. How do solar panels work during cold Alberta winters?
Solar panels actually perform more efficiently in cold temperatures. On sunny winter days, panels generate electricity just like in summer—often at higher efficiency when cells are cool. Snow can temporarily block production, but most snow slides off over time or can be brushed off safely.
4. Will installing solar panels damage my roof?
No—when installed by a certified professional, panels are mounted using non-penetrating or well-flashed mounts that protect roof integrity. Installers assess your roof condition first and ensure all penetrations are watertight. Proper installation often preserves or even extends your roof’s lifespan.
5. How long do solar panels last in Edmonton’s climate?
Most Tier 1 solar panels come with a 25-year performance warranty and can continue producing 80% of rated output at year 25. High-quality panels can last 30 years or more, even under Alberta’s freeze-thaw conditions.
6. Are maintenance and cleaning required for solar panels?
Very little maintenance is needed. Alberta’s rain and snow often self-clean panels. We recommend inspecting panels once a year for debris, shading, or damage. A light rinse or brush of accumulated dirt/snow ensures peak performance.
7. How does net metering work in Alberta?
Under Alberta’s Micro-Generation Regulation, excess solar energy sent to the grid earns you kWh credits at your retail rate. When your panels produce less (e.g., winter), you draw from the grid and these credits offset your consumption. Unused credits roll over for up to 12 months.
8. What size solar system do I need for my home in Calgary?
If your home uses ~7,000 kWh per year, a 6 kW system (about 15–20 panels) usually offsets 90–100% of your annual usage. Factors like roof orientation, shading, and panel efficiency will affect precise sizing—an installer’s site survey determines the exact number.
9. How long does solar installation take in Edmonton?
A typical residential install (5–8 kW) takes 1–3 days on site. Including permit approvals and utility interconnection, the entire process from quotation to commissioning takes 4–6 weeks during normal permitting cycles.
10. What incentives are available for homeowners in Alberta?
Canada Greener Homes Loan: Up to $40,000 interest-free for approved solar systems. Municipal Solar Rebates: Calgary and Edmonton offer up to $750/kW (max 20 kW). Net Metering Credits: Earn bill credits for surplus power sent to the grid. Carbon Offset Credits: Monetize every tonne of CO₂ your solar helps avoid by registering with certified offset programs.
11. How do I apply for the Canada Greener Homes Loan?
1. Visit the official NRCan Greener Homes website to confirm eligibility. 2. Complete the online application (utility bill proof, basic home details). 3. Wait 2–4 weeks for approval. 4. Upon approval, book your solar installation—loan funds are disbursed directly to cover equipment, installation, and monitoring.
12. Can renters in Calgary benefit from solar energy?
Direct rooftop installation requires property ownership or landlord approval. However, renters can join community solar projects—buying a share in a local solar farm—so they still receive net-metering credits on their utility bills without installing panels themselves.
13. What permits are required for solar installs in Alberta?
You need: • Municipal Building Permit (verifies structural and code compliance). • Electrical Permit (ensures wiring meets Canadian Electrical Code). • Utility Interconnection Agreement (registers your system for net metering). A certified installer typically handles all permitting and paperwork for you.
14. How do carbon credits for solar work in Alberta?
By generating renewable energy, you avoid CO₂ that would otherwise be produced by conventional electricity. Register with accredited offset programs (e.g., Alberta Emission Offset Registry). Each tonne of CO₂ avoided earns one carbon credit, which can be sold to corporations for $50–$85/tonne, generating extra revenue.
15. What is Alberta’s TIER program, and how does solar help industrial sites?
Alberta’s Technology Innovation and Emissions Reduction (TIER) program applies to industrial emitters over 100,000 tCO₂e/year. Solar installations can reduce emissions obligations. Companies can invest in on-site solar, purchase Emission Performance Credits (EPCs), or buy certified offsets generated by solar projects.
16. Are there tax credits for commercial solar in Alberta?
Federal Investment Tax Credit (ITC): Qualifying commercial solar projects receive a 30% tax credit through 2034 (then tapering). Capital Cost Allowance (CCA): Solar equipment (Class 43.2) qualifies for 100% accelerated depreciation in the first year, reducing taxable income. Combine these with municipal and provincial grants to maximize ROI.
17. How can I monitor my solar production?
Most modern inverters offer online portal or mobile app access, displaying real-time power output, daily/weekly/monthly energy production, and system performance. You’ll receive login credentials to track savings and detect any underperformance immediately.
18. What warranty should I expect on panels and inverters?
Panels: Typically a 25-year performance warranty (80% output at year 25) and 10–12 years product warranty. Inverters: Usually 10–12 years, extendable to 20 years for an extra fee. Workmanship: Reputable installers provide a 5–10 year warranty covering racking, wiring, and roof penetrations.
19. Does solar affect my home insurance in Calgary?
Inform your insurer when installing panels. Many carriers offer premium discounts for certified solar installations, as they can decrease risk and increase property value. Update your policy declarations to ensure coverage for your new array.
20. How do I choose the best solar financing option in Edmonton?
Canada Greener Homes Loan: 0% interest, up to $40,000—ideal for homeowners. Equipment Financing: Secured loans at 3–5% APR, amortized over 10 years—common for commercial installs. Leasing/PPA: No upfront cost but often higher long-term expense—evaluate net-present-value carefully. Compare monthly payments against expected net-metering savings, carbon credits, and tax incentives to ensure immediate cash-flow benefits.
