Less electricity bought from the grid
Your own production covers part of your electricity use directly. The more electricity is used during daylight hours, the more the need for purchased electricity decreases.

Solar energy
Solar panels for homes, cottages and businesses
Sun-Laatukatto handles the whole project from start to finish: we check the roof condition, assess consumption and needs, choose a solution that fits the property, and carry out the installation and commissioning.
Benefits
How can solar panels benefit your home?
An estimate based on your property
The estimate is based on consumption, roof direction, pitch and shading. This gives you a more useful estimate for everyday use.
Make better use of the electricity you generate
Using more of your own solar power during the day can reduce the amount of electricity you buy from the grid.
Suitable for different types of buildings
The system can be installed for a detached house, cottage or business property. The installation is always adapted to the site.
Production is strongest in the brighter months
Most production takes place from spring to early autumn. The system also works reliably in Finnish conditions.
Delivery
What is included in a complete solar panel installation?
The final scope is always defined according to the property and the customer’s needs. The package usually includes the following stages and technical components.
- Checking the roof condition and choosing an installation method that suits the property
- Sizing the panels, inverter and mounting system based on the site details
- A layout plan based on roof shape, orientation and shading
- A mounting system suitable for the roof type, such as Orima or Kontio Solar, together with carefully made penetrations and protected cable routing
- Required installations, measurements and system commissioning
- All required documentation and notifications to the grid company
- Inverters from recognised manufacturers such as GoodWe, Solis, Sungrow, Ledvance and others.
- Solar panels are selected from recognised manufacturers based on availability
The installation warranty is typically 5 years.
Depending on the manufacturer, inverters typically come with a 5–15 year warranty.
Solar panels typically come with a 25-year production warranty.
Why choose us
5 reasons to choose Sun-Laatukatto
We first look at the roof, electricity use and the right way to carry out the project. After that, you receive a clear proposal where price, technology and work stages are easy to understand.
Straightforward pricing
We carry out the work ourselves, including the electrical installation. Your quote clearly lists the products, work and price.
5-year installation warranty
We use high-quality mounting parts and components. That is why we can stand behind our workmanship over the long term as well.
Neat and protected cabling
Cabling is always installed in protective conduit. The result is safer and better protected against weather and damage.
A durable foundation for the solar array
When needed, we handle roof cleaning, maintenance and coating before installation, helping to create a long-lasting and reliable foundation for solar energy.
Deal directly with the team doing the work
You deal directly with the people doing the work and familiar with the property. The same team handles the whole project from assessment to commissioning, without middlemen or unclear responsibilities.

We handle the whole project, from the first assessment to commissioning.
1. Basic details
Your address, electricity use and a few roof photos are enough for an initial assessment.
2. Property check
We check the roof, shading, electrical system and installation routes so the solution fits the property.
3. Proposal
You receive a clear proposal for the system, the delivery scope and the estimated benefit.
4. Installation and commissioning
We handle the installation and checks, and guide you in using the system.
Initial estimate
Would solar energy suit your roof?
Send the basic details and we will look at what kind of system suits the building, electricity use and your goals.
What information is useful to send?
- Property address
- Estimated annual electricity consumption
- Photos of the roof, house, electrical panel and surrounding property
- Information about possible shading
- A preferred system size or the main goal
Solar panels start with the condition of the roof
Solar panels are a long-term solution, so the roof surface and mounting areas should be checked before installation. If a metal roof is clearly worn or a tile roof has moss growth, it may be sensible to carry out maintenance before installing the panels.
When the roof and solar energy are considered together, the sizing stays practical. We plan the panel layout, cable routes and use of the available roof space so the system works well and roof work does not have to be repeated.
