Cost of labor might be significant in some countries, but in a lot of countries, cost of materials is still the significant cost barrier to installation of solar. If the cost of materials were to come down significantly, even if it is at the expense of some efficiency, and also make the installation much more flexible, then definitely more installation will happen. Capital invested will be recovered in a shorter duration making the investment a lot less risky. This makes lending programs much more accessible, making the whole thing a more self-reinforcing cycle.
