Even though escaping great outdoor may seem as simple as throwing a tent, it is also critical that you also think about your energy requirements. But, at the same time you do not want some noisy generator disrupting your outdoor fun, do you? You need to get a portable solar panel because of its efficiency and convenience. The question is, will it provide the energy needed to power everything on your next adventure so don’t leave your home without these.
Portable solar devices are more like the panel system fixed on your rooftop when it comes to functionality and appearance. The difference is portable are small, so you do not need to attach them to a roof; all you need is fold them, connect, use and that it. The question is how many kWh does a portable solar panel produce? Well, the amount of electricity a portable solar panel produces will depend on three factors:
Basically, the system of portable panel operates at about 14% efficiency, which means that the panel can convert just about 14 percent of captured solar energy from the sun into power. So, a 144 watts solar system generates about 120 watts of power. This power is enough energy to charge your standard battery for about four hours and can power a laptop or whatever portable device you have for about 3 hours. You will see panels that produce somewhere between 210 watts to 320, which basically corresponds to a panel that produces in STC ( standard test condition).
Hours of exposure to sunlight determines the amount of power the solar panel will receive and ultimately the one it produces to use on your devices. If there are some shades in the clouds this means that your panel won’t produce as much power as you would have expected.
The size of your panel
The size and efficiency of your panel are two fundamental factors that determine the output production, so the smaller the panel, the less power you should expect. You shouldn’t expect portable solar to power all your household needs, because this requires around 30 Kwh, and a small portable solar panel produces about 5% -10 % of this amount. A 45 watts portable solar panel will generally give you enough to power your electronic devices or your phone.
Remember when we are talking about kWh, we are talking about the amount of work the energy uses in one hour of time. So when we say that using a 100 watts microwave for instance, or solar panel for that case for one hour would use 1kwh of energy. So don’t confuse the two, one is the measure of energy (Kwh) while the other one is the measure of power. So let’s take an example of a 250 watt STC panel. If you multiply the panel by the number of hours of sun it gets in a day you will get the Kwh the panel produces in that day. So, in the United State, the usable sun shines for about 4 hours, right? So the number of kWh you get is 250-watts times 4 hours. That about 1kwh in a day, which is enough to power pretty much all your devices on your next RV on your next trip.
Of course, a solar panel harvests energy from the sun and turns it into electricity, but you will need a few additional components in order to have a functional system. Either way, the energy you get is enough for your power needs on your next trip.
