What a Toronto solar quote usually leaves out

Solar proposals in Toronto usually cover the array in detail, but they rarely discuss the house where it will be installed.

The distance between a signed agreement and a settled invoice rarely comes down to the panels themselves. It comes down to a short set of items that cannot be priced until someone inspects the current electrical service and the current roof, and that therefore stay out of the proposal until that happens. This article covers only that list. The system price itself appears in the installation cost guide.

SolarCalculatorHQ prices a service entrance upgrade, which lets the panel support a solar array, between $1,800 and $4,000. This is the less serious form of the electrical issue.

The bigger scope is a complete panel change. Superior Power Electric prices a 100 amp to 200 amp upgrade anywhere in Ontario at $2,800 to $5,000, with the ESA permit and inspection part of the job, and City Power Electrical Services prices the same work in Toronto at $3,200 to $4,500, also with the permit covered. The two line up well enough that $2,800 to $5,000 works as the straight range.

Neither figure can be pulled from a photo of a roof. An electrician gets it by opening the current panel, so the logical sequence is to have the service checked before the array is designed, not after the contract is signed. Five of the 161 companies in this index list solar electrical work, and they are on the solar electricians page. The electrical work cost guide holds the remaining panel figures.

Superior Power Electric prices a meter base swap, when the current base is not rated for 200 amp service, between $600 and $1,400. They list it as an extra on the panel project, not as a separate job, and it is the most frequent cost overrun on a 200 amp upgrade.

Two minor items from the same list deserve mention while an electrician is already there. A second dedicated circuit runs $200 to $450. Relocating an electrical panel to a different spot costs $500 to $1,200. Choosing either one once is less expensive than adding it later, since City Power sets the Toronto service call minimum at $150 to $250 per visit, and that fee applies whether the visit lasts twenty minutes or two hours.

Bundling is the lever here. One visit that upgrades the panel, adds the solar circuit and takes care of any other electrical work means you do not pay that minimum three separate times.

A roof that will soon have different shading cannot be measured correctly for an array. SolarCalculatorHQ lists $500 to $2,500 for taking out or cutting back trees to remove shade.

That number sits outside the solar job, not within it, and that is precisely why it never appears in quotes. A contractor pricing a system is pricing a system, and the tree belongs to another crew. You still have to pay for it, and paying for it once the panels are installed means accepting a design built for the wrong roof.

Shade returns as well. Limbs that stayed clear of the panels in the first year are no longer clear by year eight, and that same $500 to $2,500 cost shows up again, against a system already putting out less than it ought to. The maintenance article lists the inspections that spot the problem early.

SolarCalculatorHQ puts snow-rated mounting hardware at $300 to $1,200 as an add-on. Beside a $25,000 system that is a rounding error, and you should still check, for two reasons.

The first reason is that specifying during installation costs much less than retrofitting onto an installed array. The second is that some Ontario municipalities demand the building permit precisely so the structure can be verified against the array weight, per SurgePV, so the mounting specification is not just a matter of durability.

When a quote leaves out the mounting hardware entirely, treat that as something to clarify, not a defect. Find out what is specified and if it carries a snow rating.

SolarCalculatorHQ prices a roof replacement for a home receiving solar panels between $9,000 and $22,000. AUK Roofers lists plywood deck replacement on an older Toronto roof at $4,200 to $8,800, a line item discovered after the old shingles are removed, not beforehand.

AUK Roofers, on that same page, prices architectural asphalt at $5.80 to $7.80 per square foot installed in Toronto. That comes to $5,800 to $9,200 for a townhome, $8,800 to $16,500 for a standard detached house, and $14,000 to $26,000 for bigger homes.

None of that should appear in a solar quote, and omitting it does not make it disappear. If the roof has only a few years left, the approach that pays a crew a single time is the one that handles the roofing first. Just 4 of the 161 companies in this index list solar roofing, so most GTA homeowners are managing two different trades. The solar roofing cost guide explains how that sequencing works.

Three separate sign-offs can apply to a GTA installation, and a quote may list just one while still stating "permits included". SolarCalculatorHQ records the ESA notification for a home setup below 10 kW at $165 plus a $95 inspection fee, and the utility hookup impact assessment at $229 through Toronto Hydro, $211 through Alectra and $306 through Hydro One. Solar Energies in Canada states the City of Toronto building permit comes to $214.79 for a solar collector system larger than 5 square metres.

Ask one by one which of the three the price includes. The permits article explains who submits each one and in which sequence.

Ontario HST sits at 13 percent, and a published figure does not always include it. Xolar states its Ontario per-watt range of $2.10 to $4.10 expressly before HST.

On a $25,000 system, 13 percent comes to $3,250. That amount is bigger than the difference between most rival bids for the same array, so two figures can appear far from each other yet state the same price, or appear the same and sit a complete tax line apart. Check which side of the tax line each figure falls on before comparing anything else about them.

Convert every proposal to a price per watt, since that is the one number that holds up when a system size changes. SolarCalculatorHQ places the GTA at $2.95 to $3.30 per watt installed, so a $30,000 quote on an 8 kW array sits above the local range and deserves a question.

Here is the rewritten block.

Then itemize what each quote leaves out, and assign costs to those omissions using the figures on this page. A bid that skips a $1,800 to $4,000 service upgrade does not cost less than one that covers it; it specifies a smaller job.

Securing three is realistic in nearly every part of this region. Among the 161 companies in this index, 149 list a phone number and 133 list a website. No company lists an email address, so first contact is a phone call or a web form. The full company list is the place to begin if your own area is one of the 23 with no listed company.
