About
Andrew runs Goldray Solar
Andrew is an Army veteran and a solar electrician. He started Goldray Solar in the Inland Empire because he got tired of seeing arrays that were installed well and then left dirty. The work is simple on purpose: show up when we said we would, and leave the glass actually clean.
Why clean solar matters
A panel only makes power from the light that gets through the glass. Dust, pollen, wildfire ash, and bird droppings sit on top and block it. The system does not shut off. It just makes less, so the savings on the bill shrink, and most people never get a warning.
Riverside and the rest of the Inland Empire can go months in summer without a rain hard enough to rinse a roof. A garden hose from the ground does not reach it. We use a power washer. Used the right way, it does not scratch the glass.
What a dirty year can cost
This is an example for a typical Inland Empire roof, not a promise for yours. A common home array is about 8 kilowatts. Clean, that is often near 13,000 kilowatt-hours a year. Southern California Edison’s average residential rate has been about 35 cents a kilowatt-hour in 2026.
| How dirty | Energy lost | About |
|---|---|---|
| Light film, about 5% | 650 kWh | $230 |
| A dry year, about 15% | 2,000 kWh | $700 |
| Ash and heavy dust, about 20% | 2,600 kWh | $900 |
A normal wash is $250 to $350. When the glass is actually dirty, that wash often pays for itself the same year. Shade, your rate plan, and how long the dirt has been sitting there all change the number. We will not invent a savings figure for your house. If you have last year’s production, we can talk through it.
How the visit is done
Andrew came up as a solar electrician. The visit is a safe wash. It cleans the glass without damaging the solar, then a deionized rinse. The same standard is why roof cleaning, windows, critter guards, and taking an array off for a new roof are on the book too.
