The Advancement Of Solar Panel Design

As technology continues to improve prices for solar panels and related hardware become more reasonable. Solar panels cost substantially less today than they did only a few years ago and offer tremendously better output per panel. Solar panels available these days are so much more efficient that you can use 1/3 less panels to create the same amount energy as previously needed.

The improvements in solar panel technology extend to other areas of the panels as well. The lastest solar panels are more durable and can take extreme weather much better than previous panels. This means they will last longer and perform at their peak for most of their useful life.

Previous generations of solar panels would become less efficient over time and would generate less energy as a result. This would mean that if their life expectancy was 15-20 years, then in the last 5 years the panels were functioning at 50-75% of their full capacity. The key issue with them was that they were very resistant to the weather and because of that they would become less productive over time.

Not only do the lastest panels last much longer than previous models, but they also keep their energy generating properties later into their lives.Another improvement to solar panels is their ability to generate electricity from sunlight that strikes them at a steeper angle. This is really important since very few homes will be perfectly positioned to catch the suns rays directly on the panel.The latest panels can still generate most of their energy capacity when used at sharp angles. This can help homes that have very nearly perfect sunlight exposure. This improvement is incorporated into most of the newer units and has not raised the solar panels cost at all.

One is the ways that modern solar panels have improved is in the way they convert the DC current from the panels to the AC current the home runs on. In older systems all the panels were connected to a junction box that ran to the inverter. This single inverter has the responsibility of converting this collection of solar panels output into the correct AC current for the home.

This was an inefficient way of doing things because of the length of electric cable required to hook to panels on the roof to the inverter which was on the ground. The newest models of solar panels come with an internal inverter, which is referred to as a microinverter.

This means each of the panels individually converts its DC output directly to AC within the panel and delivers this to the home directly.
