Advances in solar electricity production also drove down solar costs. Back in 1977, the price of solar panels per Watt of power was $76. Today, the average price is as low as $2-3 per Watt of installed
Cost per kWh shows the lifetime cost of solar electricity by dividing your net system cost by total expected energy production over 25 years. This typically ranges from 6-8 cents per kWh, compared to
Solar panels cost about $21,816 on average when purchased with cash or $26,004 when purchased with a loan for a 7.2 kW system. While that price tag seems steep, the electricity bill savings you get from solar panels
