Our online calculator will help you calculate the capacity of solar power plant, to know the total power of all appliances in the house to determine the number of solar panels and batteries.
Before purchasing and installing a solar plant on the roof of his private house you must first calculate the total power of all electrical appliances you will use in this house, our calculator will help you know the total wattage of all equipment: (refrigerator, TV, washing machine, light, heating, water heater, etc.).
Now about what you need for solar power?
Need solar batteries (panels), and must be installed on the roof of the house and very preferably on the Sunny side (important to avoid obstructions between the sun and panels), for example on a house roof area of 100 sq m, it is possible to place the panels only 15 kW nominal power and that should be enough for your needs, and the excess energy can be sold to the state at the so-called (green tariff), we can say that this solar plant will pay for itself within 7-10 years.
Need charge controller 12/24V.
Need a gel battery, then you have to decide how many pieces to buy, but keep in mind that the capacity of energy in the battery was enough at least for the needs of your home, and excess energy can be sold to the state.
Need a powerful inverter (few pieces), it depends on the power your electronics in the house.
The final circuit looks like this: solar panels produce DC 12V/24V which is supplied to the charge controller 12/24V, after which the current charges are all gel batteries and once they are fully charged the controller disconnects the batteries if you are in the home include any electrical device, current from the battery goes to the inverter and converts from 12/24V to 220V, as soon as the capacity of the battery decreases the charge controller again begins to charge them feeding current from the solar panels and the extra energy that continues to be developed after fully charging the batteries is sold to the grid state.
The average life of gel batteries is 10 years, but solar panels degrade (fade) by approximately 0.5% per year and as a consequence of falling output energy.
