Ongrid System Design

The main components for On-grid system:

⦁ Solar panels:

primary components and we calculate how many kilowatts the client needs after site survey and electrical loads analysis.

⦁ Mounting structure:

to secure the solar panels in place, either on roof or ground. It ensures that the panels are positioned optimally to maximize sunlight exposure.
⦁ Inverter:

 The crucial component that converts DC to AC (alternating current) electricity which used to power household appliances and is compatible with the electrical grid.
It is important to choose the best quality inverter possible for the budget allowed as the main considerations in grid connected inverter choice are: Power – Maximum high and low voltage power the inverter can handle and Efficiency – How efficiently does the inverter convert solar power to AC power.

⦁ Electrical Meter:

its known also as a net meter, it measures the electricity generated by the solar panels and the electricity consumed from the grid. This meter enables net metering which allows excess electricity generated by the system to be fed back into the grid for credit or compensation.

Net-metering Rules in Egypt:

The Electricity Utility and Consumer Protection Agency announced the requirements to connect a solar power plant of less than 500 kilowatts owned by the customer, as follows:

⦁ The location of the station project that is contracted with the net metering system must be within the boundaries of the client’s property.
⦁ The customer contracting with the net metering system is not authorized to distribute electricity for the same project
⦁ The total installed capacity of the solar energy stations connected to the network of the single distribution company, and contracted with a net metering system, should not exceed 1.5% of the maximum load of the distribution company registered with metering during the financial
year preceding the contract.

⦁ The installed capacity of the station – contracted with a net metering system – should not exceed the maximum load of the customer’s consumption during the fiscal year preceding the date of commercial operation of that station.
⦁ The surplus energy produced from the contracted solar plant is accounted for by the net metering system annually, after settling the customer’s consumption at the end of June of each year.
⦁ The customer pays a fee for integrating the produced energy (the merger fee), which represents the cost of integrating renewable energy into the network (according to its voltage), determined by the Agency, and reviewed and amended periodically.

⦁ Safety (Disconnect) Switches:

 Essential safety device that disconnect the solar system from the grid during maintenance, testing or emergency. They ensure that no electricity is fed back into the grid when it is being repaired.

⦁ AC breaker panel and fuses
