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.
There is a common misconception that all solar energy systems are gigantic and take up too much space on a home. The truth is, solar energy are scalable to any size. If you want a large solar array to power your home, you can. You can also choose to use something smaller that will offset normal energy costs from your local power company.

Cleaning your solar panels does not need to be labor intensive. You want to avoid abrasive soaps at all costs, as they can deteriorate and even destroy your panels. So long as there is not caked up dust or bird droppings, frequent rinses with just hose water should be more than enough.
