Get online to find your local Internet solar panel community. You can find out good information about peaks and lows in solar energy use in your area. If you get particularly adept at getting on a roof to clean your solar panels, you might can even market yourself and make a few bucks off other solar panel owners afraid of heights.
How dense your solar panels are will determine their efficiency. Getting high density solar panels may cost you quite a bit, but after a while they'll pay for themselves because they produce more power. Before you select your solar panels, you should consider panel density.
In part #7/10 of the Grand Solar Minimum Primer you will learn, if you haven’t already, that the sun’s natural cycles are the primary driver of climate on Earth not …
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.
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!
