How to display empty stars on products with woocommerce?

Add the following code to your functions.php

add_action('woocommerce_after_shop_loop_item_title','change_loop_ratings_location', 2 );
function change_loop_ratings_location(){
remove_action('woocommerce_after_shop_loop_item_title','woocommerce_template_loop_rating', 5 );
add_action('woocommerce_after_shop_loop_item_title','woocommerce_template_loop_rating', 15 );
}

And then after add the following lines also to get the rating count

add_filter( 'woocommerce_product_get_rating_html', 'loop_product_get_rating_html', 20, 3 );
function loop_product_get_rating_html( $html, $rating, $count ){
    if ( 0 < $rating && ! is_product() ) {
        global $product;
        $rating_cnt = array_sum($product->get_rating_counts());
        $count_html=" <div class="count-rating">" . $rating_cnt .'</div>';

        $html="<div class="container-rating"><div class="star-rating">";
        $html      .= wc_get_star_rating_html( $rating, $count );
        $html      .= '</div>' . $count_html . '</div>';
    }
    return $html;
}
