Solar industries Dirty Little Secrets

1) Conventional solar panels lose 3% of their efficiency the moment the new system is activated.

2) When they say "you don't pay for the solar panels, you pay for the solar power....." they are correct. It's called a PPA or power purchase agreement. If you do not consume any power at all, you will still have a solar bill for the power produced by the system.

3) Many PPA solar systems are purposely oversized. This makes the company that owns the system more front loaded money.

4) Not all solar leases are created equal, most have undesirable downsides.

5) Conventional solar does not operate properly , and may shut down on high temperature day.

6) Conventional solar can lose up to 37% of its efficiency in as little as 7-12 years.

7) Conventional solar has efficiency levels of 14-16%. Our solar averages 20%.

Black Panels


We designed our SunPower Signature black solar panels to generate the greatest amount of solar electricity per solar cell in an elegant panel.

With our SunPower Maxeon Cell Technology, we eliminated the unattractive front metal gridlines, put our wide metal contacts on the back of the solar cell, and placed the cells onto a black panel background. Not only do our black solar panels capture more sunlight, but their elegant engineering also creates a streamlined design that blends harmoniously into the roof of your home. This refined design allows our residential solar systems to integrate with a wide range of architectural styles.
  • Corrosion-resistant frames are guaranteed for 25 years (that’s longer than most roofs).
  • Tempered front glass maximizes impact resistance.
  • SunPower solar panels outperform competitors in low-light conditions, generating solar power even on cloudy days.
