How Power is Delivered

With traditional utility power, you pay a rate for each kilowatt (kWh) of power you draw from the grid plus several other charges and fees.


The energy delivery process begins at power plants, where various energy sources such as coal, natural gas, nuclear, hydro, wind, or solar are used to generate electricity. These power plants convert the potential energy stored in these sources into electrical energy through different methods, such as burning fuels, harnessing steam, or capturing sunlight.


Once electricity is generated, it’s transmitted over long distances through high-voltage power lines. These transmission lines form a network known as the electrical grid. The high voltage is used to minimize energy loss during transportation. Transformers are used to step up or step down the voltage as needed.


At this stage, the electricity enters the local distribution network. Substations within communities further reduce the voltage to a level suitable for homes and businesses. Distribution lines carry electricity through neighborhoods and streets, and smaller transformers further reduce the voltage for safer use.

Whats the Lifespan of Solar Panels?

Solar panels last but lose efficiency with time

Solar panels lose between 0.5% to 1% of their efficiency every year. Because of that rate of loss, at the end of the 25 year warranty period, the panels will still output between 75 to 87.5% of the original amount of power they made when they were new. In fact, a National Renewable Energy Laboratories (NREL) study found that 80% of all solar panels outlast their 25 year warranty period. That same NREL study also shows that 78% of the systems tested in the study showed less than a 1% degradation rate per year. You may ask, “Are solar panels that still put out 75% or more of their original output still useful?” Yes! If your panels are still putting out most of the energy they were originally designed to produce, those panels are still useful.

How solar panel longevity affects the ROI of going solar

If your panels last longer than they are warrantied for, that boosts your ROI(Return On Investment). Online calculators often use the common 25 year warranty period that solar panels come with as the basis for how long your system will last, and therefore, as a basis for how long you will own it and earn ROI. However, if your panels last for longer than 25 years, all that extra time means extra time that you are earning ROI on your investment in solar. The best way to make sure you get maximum ROI on your system is to properly maintain the system. Thankfully, there’s not much you need to do.

How to maintain your solar system so it lasts

All you need to do to maintain maximum output from your solar system is to occasionally dust off the panels. You should also keep trees trimmed and clear of your system so the shade doesn’t reduce your systems’ power output. Solar panels are very reliable and they don’t need any maintenance beyond keeping them clean.Inverters are another story. They are often warrantied for 10 years.

Demand Solar only uses products with 25 year warranties.
