Solar Panel Efficiency and Life

So, the Sun shines on Earth and in that sunshine there is energy. Plants convert that energy into mass because energy is mass. E = mc2. Energy equals Mass times a constant (which is not important here). We eat the plants for energy, or we eat animals that eat the plants. That’s how we survive.

Simple Explanation:

Well, solar panels are humans’ attempt at making “plants” that convert the Sun’s energy into energy we use – to heat, chill, or light our homes, to power our TV’s, fridges, computers, etc. Well, it’s not easy converting that sunshine into energy we can use. And as it turns out, most solar panels convert 12-15% of the Sun’s energy that falls on the panel. The Sun dumps ~1,000 W/m2 at sea level on a clear day (source: wikipedia).

The Solar Panels Don’t Matter!

Solar Panel Brand LogosStop searching for the ‘best’ or ‘most efficient’ solar panels. Stop trying to compare brands. The solar panels don’t matter. Obviously they matter in terms of the solar pv system as a whole, but which panels you use, isn’t important. Let me explain.

1.  All solar panels are warrantied for 20-25 years, which means the manufacturer guarantees the panels will still be producing at least 80% output 25 years from now. It’s the same for all brands. Don’t believe me? Ask the guy selling them.
