If your roof cannot to support the weight of photo-voltaic solar panels, you can save a lot of money by investing in thin film solar panels. These panels are very light and flexible, which makes the installation much easier and affordable. Their higher price is also justified by their efficiency.
Before signing any agreement for installation of solar energy products, get at least three estimates. Once the estimates are in your hand, read each one carefully to ensure that the installation is up to your standards. Each estimate should include a time frame of completion, a list of materials and the estimated amount of labor charged.
Do not let a salesperson pressure you into purchasing solar panels. A solar energy system is an important investment and you should take the time to compare your different options. If a vendor feels the need to pressure you, they might not be confident about the quality of their products.

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.
