How to Design And Install Solar Power System For Home

First of all, we need to understand the local grid connection policy. Whether your place can connect solar energy to the grid. Off-grid systems require batteries, and the cost will be much higher than grid-connected systems. Moreover, due to the instability of solar power generation, the grid-connected system can better recover the cost of the solar power generation system.

Second, you need to consider how much solar panel power you need. According to the daily electricity consumption, choose the solar panel with the appropriate power.

For example, a family’s monthly electricity consumption is 300 kilowatt-hours. Then the average daily electricity consumption of this family is 10 kilowatt-hours of electricity. If we use a 5kW system with an average of 5 hours of sunlight per day, the system can generate 25 kilowatt-hours of electricity per day. In this way, not only can meet their own electricity consumption, but also can upload the remaining electricity to the grid.

Be sure to condsider rainy weather and the efficiency of the PV inverter (80% – 90%). In order to make full use of the photovoltaic inverter power, we suggest that the total solar power can be greater than 10% of the photovoltaic inverter power.

Roofs are one of many options when choosing a site for solar panel installation. We must consider the following points to choose a solar panel installation site.

1. Whether the site has enough light time. As the sun rises and sets, there may be shadows around to affect the solar system to generate electricity.
2. Whether the site has enough area to arrange all the solar panels. Generally speaking, south or east-west-facing roofs are more suitable for installation. In addition, families with yards or balconies can also consider installing sun sheds, carports, or awnings.

An installed capacity of 1000 watts requires a roof area of ten square meters. Villas, townhouses, and single-family houses are suitable for installing distributed photovoltaic power generation projects. If the installation area is limited, you can consider high-power 650W solar panels or even double-sided solar panels.

The primary function of a solar inverter is to convert the direct current generated by the solar panels into alternating current that household appliances can use. Usually, the inverter of the home solar system is between 1KW and 10KW. Inverter selection should consider the following points:

1. The power required by most electrical appliances at the beginning is the peak power. This will be much greater than the rated power. Such as air conditioners, refrigerators, washing machines, induction cookers, microwave ovens, etc. Peak power impacts power generation and energy storage and needs to be appropriately increased. For example, if the total power is 1600 watts, it is recommended to use an inverter with a power of more than 3000 watts.
2. Many poor inverters on the market have a nominal power much smaller than the actual load power.
3. Be sure to consider the short input voltage and the current range of the inverter solar panel. If the output voltage of the photovoltaic panel array exceeds the input voltage range of the inverter, the inverter will not work.
4. Considering the energy conversion efficiency of the inverter and the rainy weather conditions, it is recommended to increase the solar panel’s power by 10% to 15%.

Compared with solar panels, the choice of inverter is more critical. Because the technology of solar panels is very mature. As long as you don’t buy inferior products, the life of solar panels can reach more than 20 years. The warranty for off-grid inverters is usually 1 to 2 years. The warranty of the grid-connected inverter is 5 years.

Mounting solar panels requires these bracket accessories:

Installing solar power system for home can give you a sustainable energy source for decades to come. A lot of hipsters want to store electricity. At this point you need a solar hybrid inverter. The solar home power systems bring many benefits to the home. Here are some important advantages about installing a solar power home system:

The solar home power systems use solar free renewable energy to generate electricity. It does not need to rely on traditional energy suppliers. This means you can reduce your need for conventional electricity, reducing associated costs.

Solar power is a clean energy source. It does not produce greenhouse gases such as carbon dioxide, nor does it pollute the atmosphere or water resources. By installing a home solar power system, you can reduce your need for fossil fuels.

The solar power home system is able to operate independently without an external power supply. This is especially important in remote areas where the power supply is unreliable or where power outages are common. You can store power when the solar panels catch enough sunlight and use it when you need it.

The initial cost of solar home power systems can be high. But over time, it can give you a long-term return on investment. By generating your own electricity and selling excess electricity to the grid, you can reduce or eliminate your electricity bills. There is even the possibility of generating income through the solar electric system.
