Home / Solar Power / The reality is that your solar system will work for 50 years

Something I wrote elsewhere – the gist of the story is that SolarCity sees that their solar panels last 35 years before they hit the 80% of original output mark that most consider the “useful lifetime.” This is significant because the current standard for this useful lifetime is 25 years – adding 10 mores years is a 40% increase in expected output. One of the constant challenges when considering whether to install solar is what the cost of the electricity is – we all know gas, oil and coal are cheap. But what about solar power? Well – we can now low the price per kWh by about 35%.
