What Services Do Solar Companies Offer?
Solar companies provide end-to-end solutions for residential and commercial energy needs, including system design, photovoltaic panel installation, financing (leases/PPAs), maintenance, and battery storage integration. Core services cover site assessments, permitting, grid interconnection, and monitoring via IoT platforms. Advanced offerings include EV charger integration and smart home energy management. Pro Tip: Always verify installer certifications (e.g., NABCEP) to ensure code compliance and warranty validity.

What are the key components of a solar installation service?
Solar installation involves site assessment, panel mounting, inverter setup, and grid integration. Companies use tools like Aurora Solar for shading analysis and NEC compliance checks. Tier-1 panels (e.g., REC Alpha) and microinverters (Enphase IQ8) maximize ROI. Pro Tip: Opt for systems with >22% efficiency to offset 90%+ of energy bills in sunny regions.
A typical residential solar installation starts with a site survey to evaluate roof angle, structural integrity, and shading. Engineers then design arrays using CAD software, optimizing for azimuth angles and local weather patterns. For example, a south-facing 6kW system in Arizona generates ~10,000 kWh annually. But what if your roof isn’t ideal? Ground-mounted systems or solar carports offer alternatives. Critical components include racking systems (IronRidge) and string inverters (SolarEdge HD-Wave), which convert DC to AC at 97% efficiency. Always prioritize UL-listed equipment to meet fire safety standards.
How do solar financing options work?
Solar loans, leases, and PPAs reduce upfront costs. Loans offer ownership (avg. APR 3-8%), while leases charge fixed monthly fees. PPAs sell energy at $0.10–$0.15/kWh, often with escalator clauses. Pro Tip: Compare net metering policies—some utilities credit excess generation at retail rates.
Financing solar requires evaluating credit scores, tax incentives (ITC), and payback periods. For instance, a $20,000 system with a 26% federal tax credit drops to $14,800 net cost. Leases, akin to car leases, let homeowners pay $50–$200/month for panels without ownership. However, PPAs tie payments to energy production—ideal for businesses with variable usage. But how do you avoid hidden fees? Scrutinize contracts for decommissioning costs or annual rate hikes >3%. Transitioning to ownership? Refinancing post-lease term often requires buyouts at fair market value.
| Financing Type | Upfront Cost | Ownership |
|---|---|---|
| Cash Purchase | $15k–$30k | Yes |
| Loan | $0–$5k | Yes |
| Lease/PPA | $0 | No |
What maintenance services do solar companies provide?
Routine maintenance includes panel cleaning, inverter checks, and performance monitoring. Companies use drones for thermal imaging to detect hotspots or faulty connections. Annual service costs average $150–$300. Pro Tip: Trim nearby trees biannually to prevent shading losses >15%.
Solar systems require minimal upkeep but benefit from bi-annual inspections. Technicians test DC isolators and combiner boxes for corrosion, especially in coastal areas. Monitoring platforms like SolarEdge App track kWh output—drops >10% signal issues. For example, a 2023 study found dust buildup reduces efficiency by 7% in arid zones. Automated cleaning robots (e.g., Ecoppia) mitigate this, but manual washing suffices for residential setups. What about hail damage? Most Tier-1 panels withstand 1” ice balls at 50mph, but post-storm inspections are wise.
How do commercial solar services differ from residential?
Commercial systems prioritize scale (100kW–10MW), 3-phase inverters, and demand charge reduction. Services include energy audits, tax equity financing, and REC management. Pro Tip: Commercial clients should leverage MACRS depreciation for 30%+ tax savings.
Commercial solar projects involve complex load profiling and tariff analysis. For a 500kW warehouse array, engineers design ballasted racking to avoid roof penetrations. Time-of-use (TOU) rate optimization shaves peak demand charges—e.g., storing solar in Tesla Powerpacks for evening use. But what about grid fees? Large-scale systems often negotiate wholesale net metering rates with utilities. A 2024 case study showed a California factory cutting energy costs by 62% using solar + storage. Transitioning to renewables? Commercial PPAs often include ESG reporting tools to track carbon offsets.
| Feature | Residential | Commercial |
|---|---|---|
| System Size | 5–20kW | 100kW–10MW |
| Inverter Type | Single-phase | 3-phase |
| Payback Period | 6–8 years | 4–6 years |

FAQs
Yes, most manage permitting—including structural, electrical, and interconnection approvals—but delays vary by municipality. Always confirm timelines upfront.
Can solar panels power an entire home?
Yes, with proper sizing (125–150% of usage) and storage. Net metering credits offset nighttime draw, but batteries ensure 24/7 supply during outages.
Are solar maintenance plans worth it?
For $200/year, plans cover inverter warranties and lightning damage—worthwhile given average repair costs exceed $1,000.
