Keep shade issues in mind when installing solar panels. A panel that loses a quarter of its light can lose half its power production. The main thing to keep in mind is tree foliage. Are any trees going to grow in between the panels and sunlight? Consider trimming them back a little.
Always look for a good and qualified contractor to install your solar system. Just because you are having a new technology installed on your home, does not mean that you should look for new contractors. The type of work is very specialized and having a quality contractor with a proven track record is critical to having your system installed properly
If you cannot afford a full-scale solar energy system, consider investing in a smaller one. Some vendors offer small systems designed to power a water heater or a generator. This small investment should help you save money within the next few years and you can easily expand your solar energy system by powering more appliances with solar panels.

Before installing any form of solar panels, be familiar with local rules and regulations. There are lots of places where some permits are required. The last thing you want is to have the system put it and then you are forced to remove it later.
