I used matlab to predict the solar energy so i need to predict it with the ANN model and calculated the RMSE. But every time i did it the RMSE becomes 166.9789 while it must be less than one rmse<1 . What can I do to find the best value for rmse?

You can increase the neurons in hidden layers of your ANN model or increase the number of hidden layers to decrease RMSE. However, carefully increase the value. A too high number will result in overfitting.

That’s mean use different structures for ANN?

Yes. If the current ANN is giving RMSE of 166.9789, there does not seem to be much room for improvement. You need to use a bigger structure.
