Latest Solar Power Installation Cost Table for 2026

10/08/2026 · 4 min read

Updated latest 2026 solar power installation cost table for zero-export and hybrid storage systems. Detailed estimates from NetSolar help you optimize your investment budget.

Interest in solar power installation costs continues to grow significantly among both households and businesses, amid retail electricity price adjustments and regulatory frameworks such as Decree 135/2024/ND-CP encouraging self-consumption rooftop solar power. Proactively securing a clean energy source not only relieves monthly electricity bill pressures but also ensures stability for household appliances.

At NETPOWER GREEN ENERGY CO., LTD (NetSolar), we consistently provide transparent price quotes, closely tracking PV market trends to help clients build accurate financial estimates before installation.

Factors Making Up Solar Installation Costs

The total investment for a rooftop solar project depends on various technical components and actual site conditions. Typically, the financial breakdown is allocated as follows:

Solar panels (approx. 30% of total cost): Choosing high-efficiency N-type, TOPCon, or Mono Half-cell solar panels from Tier 1 manufacturers (Jinko Solar, Canadian Solar, Astronergy, JA Solar) ensures low degradation rates and a lifespan of over 25 years.
Inverter (approx. 20%): The heart of the system, converting direct current (DC) to alternating current (AC). Trusted brands include Sungrow, Solis, Huawei, SMA, and Deye.
Lithium Battery Storage System (25% – 35% for Hybrid systems): Utilizing safe LiFePO4 battery cells with high charge-discharge cycles from Dyness, Bettenergy, and Easyway.
Racking mounting structures and electrical distribution boxes (approx. 15%): Specialized T6005 aluminum rail mounts, corrosion-resistant galvanized steel, along with standard electrical protection enclosures featuring AC/DC breakers and surge protection devices (SPD).
Transportation, technical documentation, and installation labor costs (approx. 5% - 10%).

Estimated Solar Installation Cost Table for 2026

Depending on the electricity consumption profile of each property (daytime vs. nighttime usage), technical solutions are tailored accordingly.

1. Grid-Tied Solar System with Zero-Export (On-grid Zero-Export)

This solution is best suited for households or businesses that consume most of their electricity during the day. The system automatically regulates power output according to actual load demand and disconnects during grid outages to ensure technical safety.

5 kWp System: Roof space required: approx. 25 - 30 m²; expected yield: 550 - 650 kWh/month. Estimated investment: 46 - 55 million VND.
8 kWp System: Roof space required: approx. 40 - 50 m²; expected yield: 850 - 1,000 kWh/month. Estimated investment: 75 - 85 million VND.
10 kWp System: Roof space required: approx. 50 - 60 m²; expected yield: 1,100 - 1,300 kWh/month. Estimated investment: 85 - 98 million VND.

2. Hybrid Solar Power System with Energy Storage

A hybrid system combines a storage inverter with lithium batteries, allowing excess daytime solar energy to be stored for nighttime consumption or to provide an uninterrupted power supply to critical loads during grid outages.

5 kWp System with 5 kWh Storage: Estimated investment: 95 - 105 million VND.
8 kWp System with 5 kWh - 10 kWh Storage: Estimated investment: 125 - 145 million VND.
10 kWp System with 10 kWh - 15 kWh Storage: Estimated investment: 175 - 210 million VND.

Key Considerations on Payback Period and Investment Efficiency

Many clients ask: "How long will it take to recover the investment on this system?" At NetSolar, we adhere strictly to honest and objective consulting. The payback period or actual electricity bill savings do not have a single fixed figure for everyone, as they depend closely on:

Geographic location and solar irradiance: Central Vietnam, the Central Highlands, and Southern Vietnam typically receive higher irradiance compared to Northern Vietnam during winter-spring months.
Tilt angle and roof orientation: Unshaded south- or southeast-facing roofs achieve optimal solar generation.
Power consumption behavior: Savings peak when consumption aligns with the system's generation curve, minimizing electricity purchases at higher tariff tiers.

Therefore, all profitability figures need to be analyzed based on actual electricity bills and irradiance modeling following on-site engineering surveys.

Professional Consultation and Installation Process at NetSolar

To ensure structural roof safety and long-term system efficiency, we implement a rigorous quality control process:

Receive requirements and analyze the facility's electrical load profile.
Conduct an on-site survey using tilt meters, evaluate purlin load capacity, and assess shading factors.
Develop 3D designs and prepare a detailed monthly energy yield simulation.
Provide genuine equipment with complete CO/CQ documentation and carry out installation in compliance with IEC electrical standards.
Set up remote smartphone monitoring systems and provide ongoing periodic maintenance and inspections throughout operation.
