Solar panels can be expensive, but the cost is coming down. Solar panels account for about a third of the overall cost of a home solar power system.When you go solar with Sunrun, you don't have to pay the high cost of solar panels because you choose whether you want to buy the panels or pay as you go through a lease or ppa.
Solar system costs can vary widely, depending on which incentives are available and how you choose to finance your solar system. In addition, the type of solar panels you choose and the overall size of your system can determine your solar system cost.
If you choose to go solar with Sunrun, we purchase the entire solar system for you, or you can purchase the system yourself if you'd rather do that. Our experts will select panels that are right for your home and system size that best fits your family's needs.

Types of Solar Panels
Photovoltaic panels are made of silicon solar cells —silicon is expensive and makes up much of the high cost of panels.
Monocrystalline vs. Polysilicon
Traditional solar panels (crystalline solar panels) are either monocrystalline or polysilicon.
Monocrystalline panels are more efficient than polysilicon panels, but are more expensive.
Thin film silicon panels are less expensive, but are much less efficient than crystalline solar panels. These panels typically take twice as much space to produce the same amount of electricity as crystalline panels.
Building Integrated Photovoltaics (BIPV) panels are thin film solar panels that are the same size and shape as roofing shingles. They are more expensive, somewhat less efficient than traditional crystallines, but preferred by many consumers as the best-looking option currently on the market.
Solar panels are measured in watts and are often priced in dollars-per-watt. Not all panels are created equal, and they’re priced accordingly.

Solar Power System Costs
When you purchase a residential solar system, the cost of your system also depends on its size. Larger systems will cost more as they require more panels.&
A photovoltaic system is more than its panels — it's made up of many other components, including wiring, racks, an inverter, and often a solar monitor and meter. The balance of systems and installation labor costs can drive up the overall cost-per-watt of a system.
