5kwp photovoltaic off-grid system design solution

An off-grid solar power system is a system that uses solar energy to power electric devices independently of the main power grid. During the daytime, when sunlight radiation intensity is high, the solar power system generates electricity, which is then provided to the solar inverter to support the operation of electric devices.

On-grid solar power system connects to the power grid, can sell excess electricity to the public grid. In general, it includes solar panels, grid-tie inverter, the solar power will be converted the electricity power to appliance working directly. When the solar power is off, the power grid will replenish the electricity power to appliances working.

This off-grid solar power system can produce up to 5000W of power on load, which can meet the requirements of various devices' power output. It uses lead-acid batteries for energy storage, which have a large capacity and a high cost performance ratio.

This project is a Solar PV Hybrid system for a few Micro-enterprise in a market in Moheshkhali. It will be a Grid-tied system including one or more AC circuit system with battery back-up. Dual preferable. If solar energy is av ailable, it will use from the solar PV system. If it is not av ailable, the

This off-grid solar power system adopts the commonly-used lead-acid battery as the energy storage, which has a large capacity and a high cost performance ratio. The reserved electric quantity of the storage battery is 10KWh.

In our final design, we used components and system setup as per our initial plan. We used Akh ter Group PLC as our Solar PV Modules. Nineteen units of modules were used as we need 4.75kW elec- tricity as per our assumption.
