Wind and Solar Power

Product Description

The Application of Residential Scenic Complementary Microgrid Systems.


ANE
1. Applicable scenarios:
Residential areas with access to the grid, experiencing frequent power outages, aiming for self-consumption of generated energy, energy storage for surplus electricity, and the ability to feed excess energy back to the grid. The energy storage can be charged from the grid. In the absence of a grid, the system can be switched to off-grid mode to power the loads. As global carbon emissions standards become increasingly stringent, residential scenic complementary microgrid systems are expected to be widely accepted as an important solution for customers.
2. Scenic Complementary Microgrid System:
We have designed a microgrid solution with the following specific configuration: a 5 kW variable pitch wind turbine, a 10 kW photovoltaic (PV) panel, a 48V wind turbine charging system, a 48V PV charging system, and an energy storage bidirectional inverter. These components together form a microgrid system for power supply. This system is suitable for promotion and application in Europe, America, and Southeast Asian countries, with a large market potential. This solution can be customized into several different configurations to meet various needs. For example, in addition to the above-mentioned configuration, it can also be integrated with a 5 kW wind turbine, 5 kW PV, and 24 kWh of energy storage; or a 5 kW wind turbine, 2 kW PV, and 15 kWh of energy storage; or a 5 kW wind turbine, 20 kW PV, and 80 kWh of energy storage.

 Technological Innovations:
 Adoption of World-Leading Mechanical Centrifugal Variable Pitch Technology, increasing annual power generation by 30%:
   (1) Initial large blade angle (+9°) for excellent acceleration performance and low wind speed startup at 2.5m/s.
   (2) High efficiency output of the rotor below the rated wind speed.
   (3) Pitch angle adjustment above the rated wind speed to maintain the rotor speed near the rated rotational speed, ensuring stable power output.
   (4) Wide operating wind speed range: 3-25m/s (covering common wind speeds on land) for continuous operation without the need for shutdown protection.
Automatic Safety Protection System (ASP):
   The ASP is a fully independent patented technology, pioneering in the industry. It consists of wind speed detection equipment, an intelligent control system, and brake/unbrake mechanical assemblies.
Maintenance-free Design for Three Years:
   (1) Long-term protective design for critical components ensures trouble-free operation of the unit without maintenance for the first three years.
   (2) Dual technical safeguards ensure the safe and stable operation of the wind turbine. The variable pitch control technology and intelligent safety protection system provide double protection to prevent damage to the turbine and electrical system during severe wind conditions.

 Remote Monitoring for Real-time Control:
   Real-time monitoring of the operational status and power generation data of the unit. Remote commands can be issued to remotely start, stop, and schedule the operation of the unit.

Considering the wind resources and sunlight conditions at the site, the wind turbine generates approximately 30 kWh of electricity per day, while the photovoltaic system generates another 30 kWh per day. The total average daily electricity generation is 60 kWh. Assuming a European electricity price of 0.3 Euros per kWh, the daily earnings would amount to 18 Euros, equivalent to 133.2 RMB. The annual earnings would be 18 Euros/day × 365 days = 6,618 Euros or approximately 48,618 RMB.
Based on a 5-year return on investment calculation, the equipment and installation cost is estimated at 155,900 RMB. ANE external quotation is 171,490 RMB, and the customer's external selling price is 240,000 RMB. The final customer will achieve a return on investment in 5 years. Additionally, there is a 5% sales commission.
