Carefully consider the types of solar panels you plan on having installed. Long ago, if you didn't have enough roof space, you'd need very expensive high efficiency mono-crystalline panels. There are now more advanced polycrystalline panels and even thin film panels. If you've got enough roof space, you might wish to look at the size of the panels in relation to their output capacity to avoid having insufficient panels that you need more of later.
If you are buying a solar energy system, make sure your panels can be easily adjusted. As seasons change, so does the angle of the sun. Your panels will need to be adjusted every three months or so. Make sure that you know how to do this or talk to your contractor about seasonal maintenance.

Minimize the upfront costs of solar panels by considering a lease instead of a purchase. This spreads the payments over a long-term period into monthly installments, so you could actually start saving money immediately. Still, consider how long you will be in that building, as the long-term periods usually run a decade.
If you will be ground mounting your solar panels, consider the wildlife in your area. Panels can be quickly destroyed by curious raccoons, hungry deer or hibernating squirrels. Try to place your panels in an area that is not easily accessible to such animals to optimize the lifespan of those panels.
