Solar panels in Kristianstad: power, cost and payback

A roof in Kristianstad gives a lot of power

We use a typical house in Kristianstad.

The roof has a slope of 27.0° and faces south. It has 20 panels of 420 W. Together that is 8.40 kWp.

Each kWp gives 991 kWh/kWp a year. That is a high value for Sweden. The whole roof gives 8 328 kWh a year. With 10 panels it is 4 164 kWh. With 30 panels it is 12 492 kWh.

The house uses 63% of the solar power itself. The rest goes out to the grid. Kristianstad is in price zone SE4, in the far south of the country.

Sun and snow in Kristianstad

On the longest day of summer, the sun is up for 17.6 hours.

On the shortest day of winter, it is up for 6.9 hours.

At noon at midsummer, the sun is 57.4° above the horizon. At noon in midwinter, it is only 10.5° up. Then the panels give little power. Most of the power comes from spring to autumn.

The snow load in Kristianstad is 1.5 kN/m². That is a low level for Sweden. The roof and the mounts must still carry the weight.

Cost, savings and payback

With 20 panels facing south, the system costs 131 945 kr.

The house saves 11 837 kr a year. The system has paid for itself after 11.1 years. Over 25 years, the profit is 163 980 kr.

With 30 panels, the system costs 175 927 kr. You save 16 042 kr a year. The payback time is 11 years. Over 25 years, the profit is 225 123 kr.

With 10 panels, you save 6 836 kr a year. It takes 12.9 years before they have paid for themselves. So more panels give a better result here.

The prices in this article are after the green technology tax reduction. The green technology tax reduction is 15% of the cost of labour and material for solar panels.

East or west instead of south

A roof facing east with 20 panels gives 6 977 kWh a year.

A roof facing west gives 6 978 kWh. That is almost the same.

With a roof facing west, the house saves 10 268 kr a year. It has paid for itself after 12.6 years. With a roof facing east, the house saves 10 149 kr a year. It has paid for itself after 13 years.

The difference between east and west is small. Both work if you do not have a roof facing south. The result is only a bit worse.

Does a battery pay off in Kristianstad?

With 20 panels, a 10 kWh battery costs 54 820 kr.

It saves 4 712 kr more a year. The battery has paid for itself after 11.6 years.

We expect a battery to last 10 years. So the battery must last a bit longer than that to pay off. It is close to the limit.

With a battery, the house uses 81% of the solar power itself. Without a battery, it is 63%. For a battery that stores solar power, the green technology tax reduction is 50% of the cost of labour and material.

Kristianstad compared with Lund

Lund is 69 km away.

There the roof gives 998 kWh/kWp. The difference from Kristianstad is −7 kWh/kWp. That is almost the same amount of power.

Still, the result is better in Kristianstad. The house saves 769 kr more a year. The difference in payback time is −0.8 years. Over 25 years, the profit is 19 225 kr larger.
