If solar panels are too expensive for you, think about renting them. Leasing is not as expensive as buying, and you can realize your savings sooner, like around a few weeks.
Try to choose solar panels that can have their angles adjusted easily. The angle at which the sun hits the Earth changes throughout the year. This means that the best angle to catch the suns rays can be very different between summer and winter. Ideally you want to at least be able to adjust the angle of your panels twice a year, however if you can find some that allow adjustments four times a year (spring, summer, fall, winter) that is even better.
