Short answer: A carport with solar panels from Innoventum costs between 167,000 SEK for one car and 328,000 SEK for three cars, including VAT but excluding installation. It generates 4,000–10,700 kWh of electricity per year in southern Sweden, which is enough for 20,000–53,000 km in an electric car. If a company installs the solar panels, you’ll receive a 15% tax credit for green technology on the solar panels and the inverter.
How much does a carport with solar panels cost?
Innoventum has five ready-to-build models. The frame is made of glulam, and the roof consists of the solar panels themselves, so you don't pay for both the roof and the panels.
| Model | Power | Electricity per year | Cars | Dimensions (width × depth) | Price, including sales tax |
|---|---|---|---|---|---|
| Solar Carport 9 | 4.0 kWp | 4,000 kWh | 1 | 3.4 × 5.2 m (approx. 18 m²) | 167,000 SEK |
| Solar Carport 15 | 6.7 kWp | 6,675 kWh | up to 2 | 5.7 × 5.2 m (approx. 30 m²) | 252,000 SEK |
| Solar Carport 18 | 8.0 kWp | 8,010 kWh | up to 2 | 6.8 × 5.2 m (approx. 35 m²) | 268,000 SEK |
| Solar Carport 21 | 9.3 kWp | 9,345 kWh | up to 3 | 8.0 × 5.2 m (approx. 42 m²) | 328,000 SEK |
| Solar Carport 24 | 10.7 kWp | 10,680 kWh | up to 2 | 6.8 × 7.1 m (approx. 48 m²) | 313,000 SEK |
Annual electricity generation applies to south-facing installations in southern Sweden, calculated at 1,000 kWh per kWp without additional generation from the rear of the panels.
What's included in the price?
- Carport with a glulam frame
- Bifacial glass-glass solar panels, 445 Wp each, that generate electricity from both sides
- Waterproof roof with integrated gutter, without an additional metal roof
- Hybrid inverter, battery-ready
- Ground screws instead of concrete foundations
Installation is not included, as it depends on the location. You will receive a fixed price after sending a photo of your driveway or following a site visit. Delivery time is approximately 10–12 weeks.
How much electricity does a carport with solar panels generate?
One kWp of solar panels generates approximately 1,000 kWh per year in southern Sweden when facing south. An electric car consumes an average of 0.20 kWh per km, so 1,000 kWh is enough for about 5,000 km.
| Model | Electricity per year | Enough for about |
|---|---|---|
| Solar Carport 9 | 4,000 kWh | 20,000 km |
| Solar Carport 15 | 6,675 kWh | 33,000 km |
| Solar Carport 18 | 8,010 kWh | 40,000 km |
| Solar Carport 21 | 9,345 kWh | 47,000 km |
| Solar Carport 24 | 10,680 kWh | 53,000 km |
The panels are bifacial, which means they also capture light reflected from the ground. If there is a light-colored or reflective surface beneath the carport, energy production may be higher than shown in the table. North of the Mälardalen region, it will be slightly lower.
How does the tax credit for green technology work?
When a business installs solar panels, a battery, or a charging station, you can receive a tax credit directly on the invoice:
- 15% off solar panels and inverters, including both materials and labor
- 50% off the battery and charging station
- A maximum of 50,000 SEK per person per year
For a carport with solar panels, the tax deduction applies to the solar panels and the inverter, not the glulam frame. Example: If the solar panels and inverter, including installation, cost 100,000 SEK, the tax deduction will be 15,000 SEK. The deduction applies only when a company performs the installation, not when you assemble a kit yourself. Current rules are available from the Swedish Tax Agency.
Is a carport with solar panels worth it?
It depends mainly on how much of the electricity you use yourself. Electricity that you use directly—for example, to charge your car—is worth what you would otherwise have paid for electricity, the power grid, and taxes. Electricity that you sell is only worth the spot price, and as of January 1, 2026, there is no tax credit for electricity sold.
Sample calculation for the Solar Carport 15 (6,675 kWh per year). The figures are for illustrative purposes only, so substitute your own prices:
| kWh | Value per kWh | Per year | |
|---|---|---|---|
| Personal use (60%) | 4 005 | 1.80 SEK | 7,209 SEK |
| Electricity Sold (40%) | 2 670 | 0.50 SEK | 1,335 SEK |
| Total | 6 675 | 8,544 SEK |
With a battery or daytime charging, the percentage of self-consumption increases, and so does the value. Without solar panels, you would have needed a carport anyway, so compare the estimate to the cost of a standard carport plus solar panels on the roof.
A carport with solar panels or solar panels on the roof?
| Carport with solar panels | Solar panels on the roof | |
|---|---|---|
| Location | Using the driveway | Requires a suitable roof |
| Car Protection | Yes | No |
| Production | Bifacial panels also capture light from the ground | Just the front page |
| The roof of the house | Not affected | Holes and fasteners in the ceiling |
| Near the electric car | The charging station can be installed directly in the carport | Cable Installation for the Driveway |
If you already have solar panels on your roof, the carport can be built as an extension of that same system.
Kit or ready-to-use installation?
All five models are available as DIY kits. Electrical installation must always be performed by a licensed electrician. With a DIY kit, you save on installation costs, but you do not receive a tax credit for green technology.
Do I need a building permit?
It depends on the size of the carport and whether you live within a zoning plan. As of December 1, 2025, you may build up to 30 m² without a building permit within a zoning plan, and up to 50 m² outside a zoning plan. See “Building Permits for Carports with Solar Panels—2026 Rules” for information on which models apply where.
