G12 refers to the wafer size. R+ is a specific way to cut the wafer to create cells of 210x182 mm.

What does intelligent shade management in Back Contact technology mean?

Solar Panels

Maintenance

One of the great advantages of Back Contact technology is its intelligent shade management. Thanks to the cell’s low breakdown voltage and unique architecture, each cell exhibits a built-in cell-level bypass diode function. In practice, this means a shaded cell can effectively bypass itself, reducing its energy consumption, while preventing major system-level power loss in partial shading. More importantly, this design minimises hotspot formation and supports more reliable long-term operation. For installations with intermittent or uneven shading—whether from vegetation, bird droppings, surrounding buildings, or dust, Back Contact provides a clear performance advantage.

What does TOPCon mean in solar technologies?

No items found.

TOPCon (Tunnel Oxide Passivated Contact) technology is one of the most advanced solar cell technologies available today, designed to deliver high efficiency, reliability, and long-term performance. Building on traditional PERC technology, TOPCon introduces an ultra-thin tunnel oxide layer and a passivated contact structure that significantly reduce the electron recombination losses. This means more of the sunlight hitting the panel is converted into clean, usable energy. With its blend of high efficiency, low degradation, and excellent performance in both harsh conditions and low-light environments, TOPCon has rapidly become the preferred choice for residential rooftops, commercial buildings, and utility-scale solar farms aiming to maximize energy production from every square meter.

What happens during power outages?

Maintenance

Safety

Solar Cells

The SunPower home energy storage system includes integrated backup power, allowing your home to keep running even during a grid outage. When the storage system detects a power interruption, it automatically switches to backup power in less than 10 milliseconds. It also keeps your solar panels operating - while most conventional solar systems shut down to protect the grid. That means if the sun is shining, you can continue generating, storing, and using solar energy while the grid is down.

What is an energy payback period?

Financing

In the solar industry, the payback period is the time it takes for your system’s energy savings to cover the cost of installing the system.

What is a solar feed-in tariff?

Financing

A feed-in tariff is the amount your electricity retailer pays you for any electricity your solar system generates that you don’t use or consume, and is instead fed back into the electric grid. You’ll want to work with a local solar installer who is knowledgeable about feed-in tariffs in your area, as different states have different policies.

What is Back Contact Technology?

Solar Panels

Back Contact (BC) solar cells are high-efficiency technology solar cells where both the positive and negative electrodes are placed on the backside of the cell. That means no busbars in the way, covering the front of the panels. This design effectively reduces shading area and enhances the absorption and utilization efficiency of sunlight. The founder of back-contact technology is Dick Swanson, also founder of SunPower.

What is the typical cost advantage of using shingle panels?

Financing

Solar Panels

Utility

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

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

Solar Panels

Warranty

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.
