The best solar panels are able to be re-positioned to accommodate the seasonal shifting of the sun. But if you have to have a fixed panel, choose the best compromise between positions that you can.
One of the major benefits of solar energy is that it is renewable. The sun (generally) shines each and every day, and there is no reason to worry that drawing power from the sun will somehow render it unusable in the future. Using solar energy, therefore, is a safe and reliable way to power the Earth.

Make sure to allow for adequate spacing around your solar panels. When overheated, these panels do not work effectively, and this can diminish the amount of energy they create for your family. Allowing for space between and around each panel helps to promote air flow and maximize both the functioning and lifespan of your panels.
