The tree shading your roof is probably protected
Lake Oswego is one of the most heavily treed cities in the metro, and that is the first thing we look at here. It is also the reason the obvious fix is often not available: “A permit is required to remove a tree with a trunk that is 6 inches in diameter at breast height (DBH) or greater.” Six inches is not a big tree.
What removal actually involves
The City runs several permit types (Type I, Type II, hazardous, dead, emergency, invasive) with different fees and procedures. And removal is not always the end of it: “Mitigation for removal of a native tree species under a Type II permit requires replanting with a native tree species.” Invasive trees cannot be used as mitigation.
So “we will just take the fir out” can mean an application, a fee, a review and a replacement tree. Worth knowing before it is in a sales pitch.
What we do about it, honestly
We map a full year of shade before designing anything. Sometimes the answer is a smaller array on a clear plane. Sometimes it is a ground mount or a garage roof. Sometimes we come back and tell you the shade is bad enough that solar does not pencil for your house right now.
That last one costs us a sale and saves you a five-figure mistake. Energy Trust has its own solar access standard for the same reason. A badly shaded roof does not qualify for the incentive either.

Is your Lake Oswego home a good candidate for solar?
Most Lake Oswego homes are. Four things decide it: the roof, its direction, its pitch and how much life it has left; the shade on it; the size of your electrical service; and how much power you actually use. None of them is your ZIP code.
Usually a yes
What we look for
- A roof plane facing south, east or west that the trees leave clear for most of the day.
- A composition or metal roof with ten or more years left. The panels are warrantied for 25, so the roof under them should not be the thing that fails first.
- A 200-amp service, or an electrical panel with room for a solar breaker.
- A bill worth cutting. A heat pump, an EV, a well pump or a shop is usually what puts a home in the middle of the 4 to 10 kilowatts we install most.
Still worth a look
None of these is an automatic no
- A shaded or wrong-facing roof. A ground mount or a shop roof often out-produces it, and the trench goes in the quote rather than turning up later.
- An older 100-amp panel. We check it on the first visit and price any upgrade in writing before you sign anything.
- A roof near the end of its life. We will tell you to replace it first rather than charge you to take the panels off and put them back.
- An HOA. Oregon law (ORS 94.778) makes a solar prohibition void in a planned community; reasonable rules on placement and appearance go into the design from the start.
The only way to know for certain is to have someone look. We map a year of shade, check the service panel, confirm which utility serves you, and size the system to your own bills rather than to the roof. Then a written number. No charge and no obligation.
What does a solar installer charge in Lake Oswego?
The price depends on system size, your roof and whether you add a battery, not on which town you live in. Most of the homes we do run between 4 and 10 kW. What changes the Lake Oswego number is the incentive that comes off the invoice before you pay anything.
The Energy Trust incentive comes off your price
It is paid to us, not to you. We reserve it before installation and deduct it from the project price. You do not file anything.
$3,500 per home for Portland General Electric customers, $2,500 for Pacific Power customers, on systems of at least 2 kW-DC. It is a flat amount per home, not a rate per watt. A quote showing you a per-watt Energy Trust figure is working from an old rate sheet.
Adding a battery brings its own incentive: $400/kWh up to $5,000 on PGE, $288/kWh up to $3,600 on Pacific Power.
If your household qualifies, it is worth much more
Solar Within Reach is the income-qualified version: $1.25 per watt up to $7,500 on PGE, $0.85 per watt up to $5,250 on Pacific Power, with a larger battery incentive on top.
Limits are set by county and household size and reset every June 1. They run higher than most people assume, and checking costs nothing.
What Oregon does not have
- No Oregon state tax credit. Ended December 31, 2017, never replaced.
- The state rebate is closed. Out of funding.
- The federal residential credit is gone for systems placed in service after December 31, 2025.

What permits does a Lake Oswego solar install need?
A Lake Oswego solar panel installation is the one job in our service area that can need a permit from two different systems: the building side, and possibly the tree code.
The building side
Lake Oswego does not run its own portal. “Lake Oswego has joined the State of Oregon’s full-service e-permitting system. You can now apply for permits, check the status of your permits, and schedule inspections online.”
That means your solar permit is filed on the state system rather than a city one. We handle the application, the status and the inspection scheduling through it.
The tree side, if it applies
- Any tree 6 inches DBH or greater needs a City permit to remove
- Permit types vary: Type I, Type II, hazardous, dead, emergency, invasive
- Native tree removal under a Type II permit requires replanting with a native species
- Invasive trees cannot be used as mitigation plantings

How does net metering work in Lake Oswego?
The power you send to the grid is banked as kilowatt-hour credits against your own later use, at full retail rate. Both Energy Trust utilities do this. What differs is the date your unused credits disappear.
Portland General Electric
Credits clear annually
Anything you banked and did not use by then goes to the utility’s low-income assistance program rather than being paid out to you.
Pacific Power
Credits clear annually
Residential systems up to 25 kW. Same full-retail-rate credit, same annual clearance, one month later.
That annual clearance is the reason we size a system to what you actually use instead of building the biggest array your roof will hold. Surplus you bank in July is worth full value in January. Anything still sitting there at the reset is gone, and you paid for the panels that made it.

How long does a Lake Oswego solar install take, start to finish?
The panels go on in two to three days. A full solar panel installation in Lake Oswego, from first call to switch-on, depends on the permit queue and your utility’s interconnection review. Most of that time is paperwork, and we do it.
Consultation, design and a written quote
Your roof, your shading and a year of your electric bills, then system size, equipment, warranty terms and price on one page, with the Energy Trust incentive as its own line.
Permits, install and inspection
We reserve your Energy Trust incentive first, because it has to be approved before anything is installed. Then the permit on the State of Oregon e-permitting system, then two to three days on the roof, then the inspection.
Utility interconnection and switch-on
We send the signed application and the inspection approval to your utility, they review it and set the meter, and then you switch it on.
How does Sunbridge Solar compare to a national solar company in Lake Oswego?
The panels are the same. What differs is who does the work, and in Oregon there is a second difference that costs real money: a company that is not an Energy Trust trade ally cannot reserve your incentive at all.
Sunbridge Solar
One company from the site visit to the warranty call
- Our own crew, our own license. Oregon CCB 189787. The install is not handed to a subcontractor hired for the day.
- We do the paperwork. We reserve the Energy Trust incentive, pull the Lake Oswego permits, and file the utility interconnection ourselves.
- Two warranties, both in writing. Ten years on our workmanship, 25 years on the panels and equipment.
- A local address. 421 C St Ste 5a, Washougal. The same people answer the phone in year eight.
Checking a national quote
Four things worth confirming in writing
- Whose crew is on the roof: the company on the contract, or a subcontractor hired for the day?
- Whether they are an Energy Trust trade ally, and if not, that the quote is missing thousands of dollars it can never add back.
- Who files the utility interconnection and follows it up, or whether that is left to you.
- Whether the price is a cash price or a financed one with dealer fees rolled into it.
How do I choose among solar companies in Lake Oswego?
Lake Oswego draws plenty of national firms that sell here and subcontract the install. Four questions separate them quickly, and in this city, a fifth: did anyone actually measure the shade?
Are you an Energy Trust trade ally?
If the answer is no, there is no Energy Trust incentive on your project: not a smaller one, none. Ask this before you compare any quotes.
Who does the roof work?
Ask whether the crew on your roof works for the company on the contract. Ours does, under Oregon CCB 189787.
What are the two warranties?
Workmanship and product are different things. Get both in writing, with the years.
How did you size this?
Net-metering credits clear once a year, so an oversized system gives value back to the utility. An installer who pushes a bigger array than your bills support is selling panels, not savings.
We’re happy to be compared on all four

What our Oregon customers say
Lake Oswego solar FAQs
The questions Vancouver homeowners ask us most, answered plainly.
Not without a permit. The City requires a permit to remove any tree with a trunk 6 inches in diameter at breast height or greater. Several permit types exist with different fees and procedures, and removing a native tree under a Type II permit requires replanting with a native species. Assume removal is a process, not an afternoon.
Then we tell you. We map a full year of shade before designing anything, and sometimes the honest answer is a smaller array, a ground mount, or that solar does not pencil for your house right now. Energy Trust applies its own solar access standard as well, so a heavily shaded roof may not qualify for the incentive regardless of who installs it.
Lake Oswego has joined the State of Oregon’s full-service e-permitting system, so permits are applied for, tracked and inspected through the state platform rather than a city portal. We handle the application and the inspection scheduling.
$3,500 per home for Portland General Electric customers and $2,500 for Pacific Power customers, on systems of at least 2 kW-DC. We confirm which utility serves your address before putting a figure on a quote. Checked September 2026.
We map a year of shade, review your roof and a year of your bills, and give you a written quote. We reserve your Energy Trust incentive, which must be approved before installation. We file the permit on the state e-permitting system. The crew is on the roof for two to three days. Then the inspection and your utility’s meter swap.
Not outright. Oregon law (ORS 94.778) makes a solar prohibition void in a planned community. The association can still set reasonable rules on placement and appearance, which we design around. Condominiums fall under a different chapter, because the roof is a common element.
It is banked as kilowatt-hour credits at full retail rate. Unused credits clear once a year, at the end of your annual billing cycle, and go to low-income bill assistance programs rather than being paid out. On a partly shaded Lake Oswego roof this matters more than usual, because your summer surplus is doing more of the work.
Most of the homes we do land between 4 and 10 kW, but shade moves that more here than anywhere else we work. A large house with a heat pump and an EV may still end up with a modest array simply because only one roof plane is genuinely clear.
Often, yes, and on a larger lot it can out-produce a shaded roof comfortably. The trench and the conductor run go into the quote up front rather than turning up as an extra later. It is one of the first alternatives we look at in this city.
Yes, and a battery carries its own Energy Trust incentive: $400 per kWh up to $5,000 on PGE, $288 per kWh up to $3,600 on Pacific Power, minimum 3 kWh. Tree cover and winter storms make outages a live concern here, so battery backup comes up often.
