It might not seem immediately apparent to you, but the entire human race is in the grips of a threat that is existential in scope. This threat is, of course, climate change, and it is very quickly slipping away from our ability to mitigate it in some way, shape or form. A big part of the reason why that is the case has to do with the fact that climate change is starting to become rather exponential, so if there was ever a moment where switching to renewable energy becomes your top priority, suffice it to say that you are in the midst of this moment right now.
It can be easy to let the impending collapse of society weigh on you at any given point in time, but you should know that leading solar panel companies have made some advancements that can give the dark clouds above our heads a bit of a silver lining. These companies have now created solar panels that are far more efficient than their obsolete predecessors, and you would therefore not need quite as many of them to power your home.
One thing to remember is that you likely only get four to five hours of peak sunshine on a daily basis. Hence, you need a power generation capacity of at least six thousand watts so that you can acquire enough electricity during these precious few hours. The number of panels that can handle this much wattage varies, but fifteen to twenty of them should do the trick although there is nothing wrong with buying a few spares just in case there is ever a rainy sort of day.
