Types of Solar Panels: 2025 Costs, Features, and How to
See the top recommended types of solar panels, updated pricing info, and the reasons homeowners choose each type for their solar energy.
The price of solar panels changes depending on where you live, but the average for installation is just under $29,000 or $2.75 per watt. On the high end, we talked to a solar customer in Hawaii who spent $100,000 going solar. Dion in Nevada said their 10-kW system cost about $20,000, which is about the national average price for a 7-kW system.
Monocrystalline or polycrystalline panels are the most common types of solar panels used on homes and businesses. The difference between the two comes down to efficiency and materials: Monocrystalline panels are made from pure, single silicon crystals; various silicon fragments melted together are used to make polycrystalline panels.
The type of solar panel you choose significantly impacts both cost and performance. There are three main types used in residential systems: Monocrystalline: Monocrystalline solar panels are made from single-crystal silicon. They offer the highest efficiency rates, around 15%–22%, and the longest lifespan.
Another measure of the relative cost of solar energy is its price per kilowatt-hour (kWh). Whereas the price per watt considers the solar system's size, the price per kWh shows the price of the solar system per unit of energy it produces over a given period of time. Net cost of the system / lifetime output = cost per kilowatt hour
