When i fill out my state solar energy credit, I am only seeing a credit of 581, It should be 25% of cost which was 42k and across multiple years same as fed. whats wrong?

when filling federal, we will recieve 10,500 accross years since there is a cap for each year. I was told this before by salesman and was also told to expect the same for state filing. I filed state and it didnt show me the 10k amount and that it would be carried across to next year but instead only says I get a credit of 581? What has been done wrong in the situation? I only purchased the panels for the credits.
