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.
Maximize the output of your solar panels by adjusting them seasonally. Adjusting your panels twice a year, once in the summer and once in the winter, will ensure that your panels are producing the maximum amount of energy by taking into account the earth's changing position relative to the sun.
I show you how to make eclipse glasses protectors out of paper plates and elastic, so the little ones are fully protected from the eclipse rays!
If you have a pool, don't even think of heating it any other way than solar! This is easily the most efficient use of solar power there is and it will save you a bundle. Solar heating systems cost about the same or less than conventional systems and basically operate themselves so stop wasting your money doing it the old-fashioned way!
