If you want to build up a solar panel roof to reduce the electricity bill, you should first determine the number of panels you'll need. The number of solar panels directly determines the amount of electricity the solar panels produce. Then, in this post, the author will answer everything about solar panel mount to let you have a clear understanding about the solar panel.
What Size Solar System is Needed to Power A House?
In general, a home needs 15 and 25 solar panels to fully offset utility bills with solar.
How to Calculate How Many Solar Panels You Need?
To calculate the amount of residential solar system, you need to multiply your household's hourly energy requirement by the peak sunlight hours for your area and divide that by a panel's wattage.
How Do Solar Panels Work?
In general, the whole working process of the residential solar system is simple. When the sun shines onto a solar panel, the energy from sunlight is absorbed by the PV cells and generates electrical charges in the panel. These electrical charges would move in response to an internal electrical field in the cell, causing electricity to flow. Here is the detailed working process:
●Photon Absorption: Sunlight consists of tiny packets of energy called photons. Solar panels are made up of photovoltaic cells, typically composed of silicon. When sunlight hits these cells, the photons are absorbed.
●Electron Excitation: When the photons are absorbed, they transfer their energy to the electrons in the silicon atoms of the solar cells. This energy boosts the electrons to a higher energy level, allowing them to break free from their atoms.
●Flow of Electrons: The freed electrons create a flow of electricity. However, in their excited state, these electrons need a path to flow through to create an electric current. This is facilitated by the built-in electric field within the solar cells.
●Electric Field Formation: The structure of the solar cell includes a built-in electric field, typically created by doping one layer of silicon with another element to create a positive/negative imbalance. This electric field helps direct the flow of electrons, causing them to move in a specific direction.
●Generating Electricity: As the electrons move through the cell, they create a direct current (DC) electricity flow. This electrical energy can then be used immediately or stored in a battery for later use.
●Conversion and Usage: To power homes or devices that use alternating current (AC) electricity, the direct current generated by the solar panels is passed through an inverter, which converts it into usable AC electricity.
●Grid Connection (if applicable): In many cases, solar panel systems are connected to the grid. Excess electricity generated by the solar panels can be fed back into the grid, often earning credits for the owner through net metering.
How Long Do Solar Panels Last?
The lifespan of the solar panels is mainly determined by the manufacturer's technology level and materials. In GR, all pv solar panel has 25 years linear power warranty.
What Are Peak Sunlight Hours?
The peak sunlight hours are one of the important factors that affect the number of solar panels because the solar panel only produces electricity when it has direct sunlight. Once the sun sets, it is unable to produce energy. Some areas, such as in the south, have many more hours of sunlight than those in the north.

Are Solar Panels Right For Your Home?
The decision about whether to install solar panels for your home is affected by several aspects.
First, you should assess how much sunlight your home receives. The solar panel can present the most efficiency in areas with ample sunlight. If your location experiences frequent cloudy or shaded conditions, the efficiency of the panels may be reduced.
Second, you also need to evaluate your current energy bills. If your area has a high price in energy, the solar panel may be your best option.
Third, you need to consider the homeownership duration. You need to consider the duration of stay. Solar panels have a long lifespan and can generate savings over many years, but the return on investment may take some time.
Conclusion
Finally, the solar panel roof installation involves multiple aspects, so you need to take full consideration of it. Otherwise, the solar panel for villa may not meet your energy needs. If you have no idea about the mono solar panel size installation, you can contact GR.
GR is one of the best solar panel companies in China, specializing in the development of solar panels. You can find various models and sizes of solar panels from GR.
