This estimate covers more than the panels and inverter. It includes the electrical permit and BC Hydro Net Metering application, a stamped structural engineering review, racking and flashing on the existing asphalt shingles, the 10kW array and an exterior-rated inverter near the meter, a line-side tap or breaker derate to connect to the existing 100A service, an exterior AC disconnect, and final inspection and utility commissioning. This is one project-specific estimate built from the homeowner's answers for this Abbotsford (V2T) home. It is not a guaranteed final price. A solar or electrical professional still confirms site conditions, final scope, schedule, and price. --- ## Key Project Facts | Fact | Details | | :--- | :--- | | **Location** | Abbotsford, BC (FSA V2T) | | **Utility** | BC Hydro | | **System size** | 10kW grid-tied, no battery | | **Existing service** | 100A panel (no upgrade) | | **Roof** | Asphalt shingles, 11-15 years old | | **Inverter location** | Outside, near the meter | | **Mandatory Scope** | $26,996.25 CAD | | **Possible Additions** | Up to $1,050.00 CAD for shingle or roof deck repair | --- ## Project Phases ### 1. Permits, structural review, and utility coordination - **Includes:** Apply for the electrical permit and the BC Hydro Net Metering application; coordinate the structural review and grid-tie connection requirements; perform a structural assessment of the existing roof framing and provide a stamped engineering report; coordinate and attend the final electrical inspection and manage utility commissioning for Net Metering activation. - **Why this phase matters:** An electrical permit and BC Hydro Net Metering application are required to connect solar to the grid in BC, and a stamped structural report confirms the roof can carry the array load for building-permit compliance. ### 2. Roof racking and attachments - **Includes:** Install roof attachments and the racking system for the 10kW array; flash all penetrations on the existing asphalt shingles. - **Why this phase matters:** Solar panels stay on the roof for 25 to 30 years, so the racking must be securely attached and every penetration properly flashed on the existing shingles. ### 3. Solar array and inverter installation - **Includes:** Mount the 10kW solar panel array; install an exterior-rated string inverter near the utility meter; run the DC string wiring and grounding. - **Why this phase matters:** The 10kW modules and inverter are the core of the system and the single largest cost in this estimate. ### 4. Electrical service integration - **Includes:** Perform a line-side tap or main breaker derate to integrate the solar feed into the existing 100A service panel; add labeling and circuit protection; install an exterior-rated AC disconnect switch between the inverter and the service panel. - **Why this phase matters:** A 10kW system usually exceeds what a 100A panel may handle by code; the line-side tap or derate connects the solar without a full 200A panel upgrade, and BC Hydro requires the exterior AC disconnect. --- ## Cost Breakdown | Phase | Labour Cost | Material Cost | Total Cost | | :--- | :--- | :--- | :--- | | **Permits, structural review, and commissioning** | $708.75 CAD | $2,700.00 CAD | $3,408.75 CAD | | **Roof racking and attachments** | $1,100.00 CAD | $2,600.00 CAD | $3,700.00 CAD | | **Solar array and inverter installation** | $1,500.00 CAD | $16,675.00 CAD | $18,175.00 CAD | | **Electrical service integration** | $1,012.50 CAD | $700.00 CAD | $1,712.50 CAD | | **Total Mandatory Scope** | **$4,321.25 CAD** | **$22,675.00 CAD** | **$26,996.25 CAD** | *Note: The 10kW array and inverter are the largest phase, but the permits, BC Hydro Net Metering coordination, stamped structural review, racking, line-side tap on the 100A service, and exterior AC disconnect make up the remainder of the complete estimate.* --- ## Possible Price Changes - **Brittle shingles at attachment points:** Shingles crack or fail to lift during flashing installation due to their 11-15 year age. A general contractor would replace the affected asphalt shingles at the attachment points. This example identifies approximately **$450.00 CAD** in possible additional work for this item. - **Roof deck rot:** Soft or decayed wood is identified during racking installation after shingles are removed. A general contractor would repair the localized roof deck rot. This example identifies approximately **$600.00 CAD** in possible additional work for this item. - **Keeping the existing roof:** The homeowner declined replacing the 11-15 year old shingle roof before installing the panels. If the roof fails while the panels are on it, the panels must be removed and reinstalled around the roof work. - **Choosing a 200A panel upgrade instead:** The homeowner declined a 200A panel upgrade in favour of a line-side tap or derate on the existing 100A service. Choosing a full panel upgrade instead of the line-side tap or derate would change the electrical service integration scope and cost. --- ## Frequently Asked Questions ### Is $26,996.25 the average cost of a 10kW solar installation in Abbotsford? No. It is the estimate RenoFiz produced for this specific 10kW grid-tied project using the homeowner's answers about the existing 100A service, the 11-15 year old shingle roof, an outdoor inverter, and BC Hydro Net Metering. Another home can have a different scope and cost. ### Why does a 10kW system on a 100A panel need special electrical work? A 10kW system usually generates more power than a standard 100A panel is allowed to handle by code. In this example the homeowner declined a 200A panel upgrade, so the electrician connects the solar with a line-side tap or a main breaker derate on the existing 100A service. ### Why does the age of the roof matter for a solar installation? Solar panels are designed to stay on a roof for 25 to 30 years. The shingles in this example are 11-15 years old, so the estimate includes a structural review and flags possible repairs to brittle shingles or roof deck rot found during installation. The homeowner chose to keep the existing roof. ### What could change this estimate? Brittle shingles that crack during flashing (about $450 in this example) or localized roof deck rot found after removing shingles (about $600). Keeping the existing roof also leaves the future risk of removing and reinstalling the panels if the roof later fails. ### Can RenoFiz provide the final contractor price? RenoFiz creates a scoped estimate from the information provided. A professional still confirms roof framing capacity, the feasibility of a line-side tap or derate on the 100A service, permits and BC Hydro Net Metering, final scope, schedule, and price before work is booked. --- ## Get a Custom Estimate for Your Project Your roof and electrical service will have their own scope and cost.
