Sunrun partners with LG to install their high quality solar panels. They offer a variety of panels that differ in efficiency and cost to fit each homeowner’s individual needs.

LG manufactures the Neon R series, which consists of panels with some of the highest efficiencies in the industry. The series ranges in watts and efficiency, but the model with the highest efficiency operates at 22.3%, and the model with the highest wattage is 440W.

The less expensive LG panels still operate at a respectable efficiency of 15-20%.


SunPower designs and produces their own panels through Maxeon Solar Technologies. They manufacture a Maxeon 3 and Maxeon 6 series which vary in wattage between 355W and 440W and in efficiency between 22% and 22.8%.

The Maxeon 6 DC 440W and Maxeon 6 AC 440W can be up to 22.8% efficient, making these models the most efficient solar panels in the industry.

Financing Options


Sunrun offers four different financing options to work around any homeowner’s needs and budget.

First, Sunrun offers a monthly lease. There can be $0 down, and a monthly payment is made to Sunrun each month. Even though Sunrun owns the system in this option, it is their customers’ favorite option for the low upfront cost.

The next option Sunrun offers is a full lease. This means you pay one upfront payment to Sunrun, which would be the equivalent of 25 years of energy cost. This option can be beneficial for a homeowner who doesn’t want to make a monthly payment and isn’t ready to buy the whole system yet.

Next, there is a full purchase option. You would pay Sunrun to own the entire system, which would make you the owner of your system and allow you to avoid any monthly payments.

The last option available is a monthly loan. This payment would be made monthly to a loan provider, but you would own the system as the homeowner and it would cost $0 upfront.


SunPower also offers a couple of different financing options. If you cannot afford to purchase the system upfront, they have two other options: buy your system or buy your power.

In the buy your system option, you can make low payments during the course of your contract with SunPower. This can be started for as low as $0 upfront. If you are looking to increase the value of your home, this could be a good option for you.

The buy your power system option is a bit different, because you do not own the system yet. If as you are making low monthly payments during your contract you decide you want to purchase the system, you can always pay it off early.



Sunrun’s warranties differ depending on which financing option you choose. They generally offer 10-year warranties, which includes replacement and repairs on equipment, parts, and labor.

However, if you choose the lease payment option, the warranty will last 25 years and includes monitoring, insurance coverage, and roof penetration on top of the maintenance, replacement, and repairs.


SunPower has a 25-year Complete Confidence warranty that covers the entire solar system. They will repair and replace parts with no additional cost to the homeowner.
