About Heliogold
Founded in 2016, Heliogold grew into a recognized solar brand across San Diego County, the Coachella Valley, and the Imperial Valley. The Heliogold trademark was registered in 2025.
Heliogold is owned and operated by CEO/General Contractor Jason Castelhano, along with managing partners Quinnten Brown and John Jackson.
Track Record
Heliogold built its reputation on installation quality, clear communication, and customer experience. The brand has received performance recognition for customer service and was recognized by SunPower as a Master Installer in 2024.
Corporate Transition (Important)
From 2021 to 2024, Heliogold was an exclusive dealer for SunPower Corporation. SunPower declared bankruptcy in 2024, and the prior California corporation historically associated with SunPower (by Heliogold) is no longer active.
As of January 1, 2026, services marketed under the Heliogold name are offered by HelioBuilders, Inc., doing business as Heliogold, a separate legal entity.
To ensure full transparency:
- Any proposal, contract, and invoice will clearly identify the contracting party and applicable CSLB licensing.
SunPower Legacy Clients
Any legacy clients who purchased SunPower through the previous Heliogold California entity will be serviced and assisted through any warranty claims available per direct manufacturer warranties, where applicable.
