We customize the solar energy storage system for each unit of the house
(MECC is the professional and reliable manufacturer and suppllier of
Solar Energy System and off grid and hybrid solar energy storage system
for Residential and Commercial application.
We can provide EU standard and US Standard Solar Energy Storage System.)
Project Description
2 sides of the roof, north and south, 2 sides are unobstructed, with a usable area of approximately 70 m²;The home wiring is aging and the power goes out often during peak hours.Power outages may occur in severe cases due to the soaring energy.The home has 24-hour monitoring and emergency lighting, which will not work in a power outage; The Owner plans to install heat pumps and increase heating equipment.
Users consume 30,847 kWh of electricity per year.Based on peak and valley hours (peak hours 6:00~22:00, valley hours 22:00~6:00 the next day), 17,543 degrees per year for peak hours and 13304 degrees per year for valley hours.
Project Summary
The user originally had plans to add a heat pump. which in itself required wiring modifications to the house. We hope to take this opportunity to fully optimise the electrical system of the entire house.This optimization aims to solve two problems:
1. Risk of power failure: 24-hour power supply for monitoring and emergency lighting cannot be guaranteed.
2. High electricity cost: more power-consuming equipment and high power consumption; large peak-to-valley price difference, and the third ladder cost is high.
Project scheme design ideas
1.The residential area has four distinct seasons and sufficient sunlight and the roof area on the east-west and north-south sides is suitable and unobstructed.The customer wants to reduce the cost of electricity and ensure safety. On balance, it is recommended that a light and storage system be installed to achieve the two main functions of "back-up power" and "stepped time-of-use tariff".That is to say, it can ensure that important loads will not be cut off in case of power failure; Reduce the electricity purchase, especially the third ladder of the electricity bill, and realize charging in the valley and discharging in the peak.
2.The user's roof can be laid on an area of about 60㎡, and then combined with the common types of modules on the market and the user's opinion, finally choose JinkoSolar 300Wp modules.Combine the component parameters, the hard conditions of the house, and the user's needs for the whole system. Hybrid inverter is recommended
Conclusion
In areas with tiered electricity prices and peak and valley tariffs, light and storage systems can effectively cut electricity bills.When designing the optical storage system, especially when selecting the battery capacity, we can break the previous concept, and no longer only select the capacity for the power required by the load, but also consider how to minimise the electricity bill through the battery by looking at the composition of the local electricity bill.This project is precisely to cut the third tier electricity bill, while moving the peak electricity consumption to the valley hours as much as possible, and finally choosing the most cost-effective 10-degree battery to achieve the maximum cut in electricity bills and recover the cost of energy storage as soon as possible.
