Frequently Asked Questions

Curious about how much energy solar panels actually produce and how it translates into savings? You're in good company. Many of our customers share these questions, and we're here to provide the answers.

Are solar panels worth it?

Solar panels can be a worthwhile investment, especially in regions with abundant sunlight and favorable incentives. They offer numerous benefits, including cost savings on electricity bills, reduced environmental impact, and potential increases in property value. Solar panels typically pay for themselves over time through energy savings and potential government incentives, making them an attractive option for many homeowners and businesses interested in sustainable energy solutions and long-term financial benefits. The return on investment, however depends on factors like your energy consumption, location, available incentives, and long-term goals. That's why we recommend to conduct a thorough evaluation and consult with one of our solar professionals to determine the specific economic and environmental advantages for your situation.

What is the typical cost advantage of using SunPower Performance panels?

Costs vary from project to project. Performance panels generally have a price point that is competitive with Conventional Panels.

Does my system work at night?

Sunlight must be present for the system to generate electricity. At night, your system will hibernate, and your inverter will display a blank screen.

What is the warranty and coverage for SunPower Performance solar panels?

A better product, should have a better warranty, and that is why SunPower Performance panels have a comprehensive 30-year warranty that covers Power, Product and Service (subject to terms and conditions that can be found in our warranty documentation).

Our latest generation, SunPower Performance solar panels are manufactured for long-term durability—covering defects related to workmanship and materials for a full 30 years. The 30-year warranty for SunPower Performance solar panels requires registration, otherwise our 25-year warranty applies, and this warranty is not available for earlier generation SunPower Performance solar panels, where a 25-year warranty applies.

Some manufacturers of standard panels go as low as 12 years on their product defect warranty, which could leave your organisation open to risk if anything should go wrong with the panel. It is best to carefully review warranty documentation before investing in solar panels for your organisation.
