Solrapport

Solrapport tells you how many hours of direct sun a place in Norway gets in a year. It doesn't assume flat open land: it computes the sun hour by hour against the real horizon, using terrain, trees and buildings from Kartverket's 1 m surface model.

Ask Claude things like "How much sun does Alpinvegen 43A in Trysil get?" or "Is this cabin plot sunny in winter?", and Claude looks up the figure.

Two read-only tools:

• sun_hours: takes a Norwegian street address and returns direct-sun hours per year with an uncertainty range, plus a link to the address page on solrapport.no.
• sun_hours_at: takes a WGS84 latitude and longitude, for places without an address such as a plot, a cabin site or a viewpoint.

Both tools answer in Norwegian or English.

For areas computed before, the answer comes back at once. For an area nobody has asked about yet, the tool starts the calculation and returns status "computing" with a suggested wait. Calling again after that gives the result, usually within a few minutes.

No sign-in is needed, and the server doesn't store anything about you beyond normal access logs (see the privacy policy). The free answer gives the yearly figure. The full report, with monthly figures and sun maps, is sold on solrapport.no.
