Apex Solar - Solar System

What Apex Solar - Solar System does

Apex Solar Power (DBA Apex Solar - Solar System) is a privately held, owner-operated solar energy company founded in 2005 and headquartered in San Jose, California, with operations extending across the United States and into Canada and Mexico. The firm designs, sells, installs, and services custom-engineered solar power systems for residential, commercial, industrial, government, and telecommunications customers, with a particular emphasis on battery-based and off-grid configurations where grid access is unavailable or unreliable. Core products include off-grid systems (500 W to 50 kW+), grid-tie systems, grid-tie with battery backup, MAPPS (Modular Autonomous Photovoltaic Power Supply) portable industrial units certified for hazardous locations, and self-install grid-tie kits shipped nationwide.

The underlying technology is a hybrid solar platform combining PV arrays, wind, hydro, batteries (flooded lead acid, VRLA/AGM/GEL, and LiFePO4 with BMS units such as Atlas and Orion), inverters from multiple manufacturers (Xantrex, SMA, Fronius, Outback), and proprietary engineering of component integration rather than a single-vendor stack. Revenue is generated through one-time equipment sales, professional installation services limited to California, repair and maintenance on legacy and new systems, and DIY/self-install kit sales with phone-based technical support. The go-to-market is sales-led and content/referral-driven, relying on a company website, blog, Facebook and Yelp presence, customer testimonials, and direct quote consultation rather than paid acquisition or channel partnerships. The firm holds a Better Business Bureau A+ rating and operates with 101-250 employees under principal Farrel Williams, with no disclosed institutional capital, M&A activity, or public-market participation.

Core offering

Apex Solar designs, sells, and installs custom solar power systems for residential and commercial customers. Core offerings include off-grid autonomous systems (500W to 50kW+), grid-tie net-metering systems, and grid-tie with battery backup hybrid systems, complemented by professional installation in California, self-install kits shipped nationwide, MAPPS portable industrial solar units, and ongoing repair and maintenance services.

Product overview

Apex Solar is a solar energy system design, installation, and maintenance company serving residential and commercial customers in California and nationwide. Its product portfolio consists of three core solar system types—Off Grid (completely autonomous, battery-stored systems), Grid Tie (utility-connected systems that feed excess power back for credits), and Grid Tie with Battery Backup (hybrid systems combining grid connectivity with battery-based standby power)—supplemented by a range of services and specialized offerings. These include solar panel and inverter repair/maintenance, custom battery storage systems (lead acid and Lithium Iron Phosphate with BMS), MAPPS (Modular Autonomous Photovoltaic Power Supply) portable industrial solar power systems for telecom and research, self-installed grid tie packages with major-brand components (Xantrex, SMA, Fronius, Outback inverters; Unirac mounting hardware), remote power systems for off-grid industrial locations, and standby/backup power systems for homes and businesses. The company packages all products as custom-designed solutions and offers DIY/self-install options alongside full professional installation in California.

Products and services

• Off-Grid Solar Systems Standalone solar power systems completely disconnected from the utility grid, using batteries to store energy from solar panels and optional wind or hydro inputs. Available in capacities from 500 Watts to 50,000+ Watts with Lithium or lead acid battery options providing one to four days of backup power. Targeted at residential and commercial customers seeking energy independence.
• Grid-Tie Solar Systems Solar power systems connected to the public utility grid that feed excess energy back through net metering for utility credits, offsetting electricity costs without battery storage. Designed for residential and commercial customers who want to maintain grid connectivity.
• Grid-Tie with Battery Backup Systems Hybrid solar systems that combine grid connectivity with battery storage for standby power. When the utility grid fails, the battery backup continues powering select circuits from the solar array during the day and from batteries at night, automatically reverting to grid power when restored. Targeted at homes and businesses needing both net metering and outage protection.
• MAPPS Portable Power Systems Portable, stand-alone solar electric power systems designed specifically for industrial applications including telecom outposts and nature research sites. UL certified for Class I, DIV. II hazardous locations and available with 12, 24, or 48 VDC or 110 VAC output. Built to withstand extreme temperatures and provide reliable electricity without regular refueling visits.
• Battery Storage Solutions Custom-designed battery storage solutions integrated with solar systems, offering flooded lead acid, VRLA sealed batteries (AGM, GEL), and Lithium Iron Phosphate (LiFePO4) options with battery management systems. Includes battery bank cleanup and upgrade services for older systems. Targeted at customers needing backup capacity and system modernization.
• Self-Installed Solar Grid-Tie Systems Pre-programmed, partially assembled grid-tie solar packages sold with or without battery backup, including solar modules (170-230 Watt sizes), Xantrex/SMA/Fronius/Outback inverters, Unirac mounting hardware, DC combiner boxes, MC array cables, AC disconnect boxes, and installation checklists. Designed for DIY installation with phone-based technical support available six days a week. Targeted at homeowners and businesses outside California seeking self-install options.
• Solar Panel Repair and Maintenance Services Troubleshooting, repair, and maintenance services for existing solar installations, including inverter diagnosis, production drop analysis, damaged or cracked panel replacement, battery inspection and replacement, panel removal for roof work, and component upgrades. Targeted at owners of existing solar systems needing service or modernization.
• Professional Solar Installation Services End-to-end professional installation services for custom-designed solar systems in California, covering site assessment, permitting, installation, and post-installation walk-through support. Targeted at residential and commercial customers purchasing complete solar systems in California.
