ixed solar panels should, wherever possible , be oriented towards the south in the northern hemisphere (and north in the southern hemisphere) . Also it is common that the slope is equal to the latitude angle ( angle formed by Ecuador , the place where you will find the panel and the center of the earth). There are some corrections for these angles to get more sunlight during certain specific hours of the day. There are solar panels installed on tracking systems that constantly orient the panels every hour and every day of the year so that the suns rays always perpendicular as possible. The energy of the suns rays that reach the earths surface is estimated at nearly 1000watios per square meter , but this value changes depending on where the planet and atmospheric conditions . What happens is that the solar panels have a very low yield, which rarely exceed 15 % (although it is more often than not reach 10% ) . Thus, a 1x1 meter panel would hardly 100w power during peak hours ( in which the suns rays more perpendicular incidence ) . However, in a house a couple of solar panels may be sufficient thanks to a battery system to store energy. This is because, although there are devices that consume far more than those 100w housing , these only a few hours a day and the batteries are those that provide that power , and the other hour energy is used less than the captured by the panels so that this energy is used to recharge the batteries. There are methods for more accurately the power available every day of the year, but are somewhat complicated unless you have a computer program that will automatically calculate. Review Comment
