How to Buy Residential Solar Power

Ready to take the first step toward energy independence? Below are some questions to consider when buying solar for your home. We’ve made purchasing a residential solar system from SunPower simple and straightforward.
 

Is your solar panel installer a certified, trained professional? Do they have a valid, unexpired, contractor's license?

 
Ask if he or she is a licensed and insured solar energy specialist trained for residential solar power installation. All SunPower® solar installers are handpicked and rigorously trained to be your solar advocates, providing careful but timely installation and responsive service.
 

Should your household be 100% solar?

 
Generally, the most economical choice for homeowners is to combine solar energy with electricity provided by your utility. With solar, you can offset the most expensive electricity (usually during the day) and purchase electricity from the utility when it’s cheaper (usually at night).
 

Is your solar installer recommending storing solar energy with battery systems?

 
We believe this is unnecessary. Batteries are complicated, expensive, short-lived and require more maintenance.   Excess solar energy generated by a SunPower solar system is sent to your utility’s power grid and will offset portions (or all) of your electricity bill. This is called Net Metering and could offset your bill by up to 100%.
 

How does the amount of power my solar energy system is capable of producing differ from the amount of actual electricity it will generate?

 
Residential solar systems are often described in terms of the amount of power they are capable of producing in a given instant (measured in watts or kilowatts).   The most important factor to take into account, however, is the amount of actual electricity the system is expected to generate during its lifetime (measured in kilowatt-hours). When compared to other brands, SunPower solar panels produce the most electricity in a range of conditions, over the lifetime of your solar energy system.
 

Are there other energy efficiency measures you can take for even greater cost savings?

 
Yes. And they’ll not only save you money, they’ll also help save the environment. Your residential solar system is just the first step toward a carbon-neutral home. Check out TLC's checklist to learn more.
 

What kind of warranty does the solar panel manufacturer offer?

 
A good solar provider should guarantee their product for a large part of a panels life. Most companies will however warranty only 10 years. SunPower's warranty is one of the best in the industry and covers performance and product for 25 years.
 

Do you think that all solar power is created equal?

 
Solar technology can vary widely. SunPower holds the world record in solar efficiency—SunPower solar panels generate about 50% more power than other solar panels and about four times more power than thin-film technology. More power cuts your electricity bill and delivers a greater return on your solar power investment for years to come. High efficiency solar panels from SunPower take up a fraction of the space compared with other systems, while delivering the same amount of power. That’s a big plus if you have limited roof space.
 

Does the monthly payment option sound too good to be true?

 
You should review the solar lease proposal and contract carefully before choosing the one that's right for you. The best solution will maximize the amount of energy the system produces while minimizing your monthly utility bill for both the short and long term.
 

How much will I need for the initial deposit on my solar system lease?

 
If you are leasing the solar system your installer should not request or accept any deposit from you. If you are getting a pre-paid or partial pre-paid lease your first payment will not be due until the system is fully installed.
