Step 1: Solar Installation Planning & Safety

Determine Compatibility

Firstly, you need to check the suitability of your home, checking the roof structure, orientation and floor space to ensure it is suitable for installing solar panels. You’ll want to know in advance how much sunlight your home receives throughout the year. Areas with longer hours of sunshine typically produce more electricity and are a key factor in solar panel efficiency.

Evaluate Energy Needs

Determine the size of the solar system you need by considering your average electricity usage over the past year and any changes you expect in the future to determine your energy needs. You can also choose to create more energy and sell it back to the suppliers to earn back the difference.

Roof Condition

Before installing solar panels, you need to make sure that your roof is in good condition and that your roof has sufficient structural integrity to bear the weight of the solar panel system. This is usually evaluated by a professional.

Get Permits

Solar panel installation involves a number of legal and regulatory requirements that you need to understand and comply with. After checking local laws and regulations, you can start applying for relevant licenses. Generally speaking, waiting for permit approval and subsequent inspections is a time-consuming process.

Safety Considerations

Before installation, we need to consider a series of safety issues, and ensuring safety is crucial. Prepare safety equipment and protective measures in advance, and take appropriate anti-fall measures when working at heights. Conduct safety checks on equipment and systems to ensure all operations and compliance with strict safety standards.

Step 2: Tools and Materials Needed for Solar Panel Installation

The materials and tools required for solar panel installation vary greatly depending on the needs and location, so selecting the right and high-quality equipment and tools is key to ensuring the long-term efficient operation of the system. Before purchasing, you need to perform performance evaluation and standard certification of equipment and tools, and select a highly reputable manufacturer. During the purchase process, you not only need to consider the purchase cost of the equipment and tools, but also its long-term operation and maintenance costs. Knowing about local solar subsidies and incentives in advance can also help you reduce investment costs.

Step 3: Installation process

Mounting brackets

Select the appropriate bracket according to the roof and ground, position the bracket accurately to ensure that your solar panels are exposed to the sun to the greatest extent to improve energy collection efficiency, and install the bracket system according to the instructions after measuring and marking.

Install battery panel

First, mount the solar panel on the bracket and secure it in place with suitable fixtures. Then connect the cables between the panels, making sure the connections are secure and meet electrical standards.

Install radiator

Choose the right type and size of radiator to install around your solar panels. The function of the radiator is to keep the panels working at a suitable temperature by reducing the heat generated by the solar panels, thereby ensuring long-term stable operation of the system.

Install charge controller

Next, install the charge controller. The role of the charge controller is to manage the flow of electricity generated by the solar panels and make the electrical connections. You need to install the charge controller between the solar panel and the battery pack, and you can set parameters to prevent overcharge and overdischarge.

Install battery pack

Battery packs are a key component in storing the electricity generated by solar panels and can store excess electricity generated. Install it in a suitable location and link it to the charge controller. You need to ensure that the battery pack is securely secured and well ventilated to prevent overheating.

Step 4: How Do You Wire Solar Panels

Inverter installation

Because the power from solar panels and batteries is direct current, it must be converted to alternating current before it can be used in home wiring. Therefore, you need to install a power inverter. Inverters are usually installed close to solar panels and battery banks to reduce power transmission losses. Also, choose a location closer to the battery pack and power access point to increase system efficiency by reducing cable length. The installation location should be as far away from humid and high temperature environments as possible to ensure the normal operation and life of the inverter.

Install meter

The meter is usually located close to the inverter and power access point. After the meter is installed, it is parameterized and calibrated to ensure accurate measurement of the power generated by the system.

Electrical connections

Determine the correct connection points, usually related to the inverter, battery bank and meter. Then follow the instructions to correctly connect the DC and AC cables to ensure that the electrical connection complies with safety standards and regulations. Finally, comprehensive electrical testing is performed to ensure proper connections between the various components of the system, ultimately ensuring efficient operation of the solar system.

Step 5: Maintenance and subsidies

Solar panel maintenance

Solar panel maintenance is very simple. You just need to regularly clean the panel surface and check the cables and connections to make sure they are working properly.

Incentives vary from place to place, making the most of your solar investment. Before you begin installation, you can explore these incentives and may be able to obtain tax credits, rebates, or grants from multiple sources to offset the costs. Overall, this enables your project to be funded by a loan. In addition, you also need to learn about local policy subsidies to provide financial support for the construction and maintenance of your solar system.

Solar Panel Installation FAQ

How do solar panels work?
Solar panels absorb solar energy throughout the day and convert it into direct current. It works based on the photovoltaic effect, and most homes and businesses run on alternating current (AC), which requires an inverter to convert the DC power into usable AC power.

Will my solar panels generate electricity when there is no sunlight?
The amount of electricity produced by solar panels depends on sunlight, and when there is no sunlight during the day, your solar panels will produce less energy. To solve this problem, solar systems are equipped with battery packs that can store electrical energy. Store excess electrical energy in the battery and supply it to the system when there is no sunlight.

If I have solar panels, will I still receive an electric bill?
You will still have an electricity bill, but with a solar panel system, your energy bill can be significantly reduced.

Will solar panels work during a power outage?
If your solar panel system is connected to the grid, it will shut down during a power outage. There are certain inverters you can purchase to provide backup power in the event of a power outage.

How much does it cost to maintain solar panels?
Solar panels are relatively low-maintenance and generally require little maintenance for 25 to 35 years of generating electricity. Specific maintenance costs depend on the size and configuration of your system, so it is recommended that you contact your solar system installer or maintenance service provider in advance to obtain an accurate cost estimate.

What happens if there is snow on the solar panels?
If your panels are covered in snow, your solar panels won’t be able to collect sunlight, so they won’t be able to generate electricity. The reality is that most panels are tilted at an angle where snow will slide off, and if it does accumulate snow, you will need to clean your panels.
