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 has improved so much that now your can generate the same amount of electricity with 1/3 less panels than it previously took.

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 for the final 5 years of a 15-20 year life cycle, the panels would run at 50-75% efficiency. One of the major problems with them was that they became less efficient at producing electricity over time, mainly because the panels were succeptable to the weather.

Modern solar panels are more durable and they will continue to generate electricity even at the later stages of their life expectancy.One more advancement in solar technology is that the newer panels will still generate power when the sun hits them at a sharp angle. This is really important since very few homes will be perfectly positioned to catch the suns rays directly on the panel.These new panels can tolerate these angles better and still generate the bulk of their power. This can be very helpful for homes that are right on the edge of having the perfect 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 panels, this DC current was run from each solar panel to a main junction box that was connected to a large inverter. The role of the inverter is to switch all the solar panel’s energy into AC current, which the home needs.

This configuration is fairly inefficient do to the length of wire needed to attach the solar panels on the roof of the house to the inverter on the ground near the house’s breaker panel. With the newer panels, they each have their own inverter called a microinverter that is built into the panels.

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