1. Do All Solar Suppliers Offer Installation Services?

Not all suppliers offer installation. Some provide only solar components (panels, inverters, batteries, mounting systems), leaving the buyer to handle installation through a third-party contractor. At Sunpal, we offer:

• Full-service installation in select regions through authorized partners
• Remote technical support for DIY or third-party installations
• Pre-configured system kits with clear instructions

Tip: When purchasing, always ask whether the service includes installation or if it must be arranged separately.

2. What's Included in a Solar Installation Service?

A standard home solar installation typically covers:

• Site inspection and roof condition assessment
• System design & layout, including panel orientation and shading analysis
• Structural & electrical installation by certified technicians
• Connection to the grid (for on-grid or hybrid systems)
• Performance testing & commissioning
• User training on basic operation and monitoring tools

Optional services may include EV charger integration, battery storage installation, or custom racking solutions.

3. Onsite vs. Remote Installation Models

Depending on your location, Sunpal offers:

Installation Mode	Suitable For	Advantages	Considerations
Onsite Installation	Homeowners with little technical experience	Turnkey, worry-free, often includes warranty	May be limited by region or logistics
Self-Installation Kit	Technically skilled users or remote locations	Lower labor costs, flexible scheduling	Requires electrical knowledge and permits
Authorized Local Partners	Areas with strong installer networks	Fast response, regional expertise	Vetting of partners is crucial

4. How to Choose a Reliable Installer?

If installation is not provided by the manufacturer, here are some tips to find a good contractor:

• Certification: Look for licensed electricians or NABCEP-certified installers
• Experience: Prior experience with solar projects of similar size
• Warranties: Labor and workmanship warranties should be clearly stated
• References: Ask for photos or testimonials from past installations
• Permits: Ensure the installer can handle local permit applications and grid interconnection

5. Post-Installation: What Support Should You Expect?

After installation, a professional supplier should offer:

• Monitoring guidance: App or web platform to track system performance
• Warranty documentation: For hardware and workmanship
• Maintenance advice: Cleaning, inspection frequency, etc.
• 24/7 support: For any system faults, alerts, or upgrade needs

Sunpal provides ongoing technical support and remote diagnostics for all system owners, regardless of who performed the installation.

6. Cost Considerations

Installation costs vary depending on system size, location, roof type, and local labor rates. A rough estimate:

• Small residential system (3–5kW): $1,000–$3,000
• Medium (6–10kW): $2,500–$5,000
• Large (>10kW or with storage): $4,000–$10,000+

These figures usually exclude system hardware and include labor, wiring, safety equipment, and grid connection.
