How to selet and install solar panels for your household solar system? 


Solar panels are the core components of solar energy systems, converting solar energy into electricity to provide us with clean and renewable energy. When purchasing and installing solar panels, it is necessary to understand the following aspects.


1.Types of solar panels

Solar panels are mainly divided into three types: monocrystalline, polycrystalline, and amorphous silicon. Monocrystalline solar panels have the highest conversion efficiency, but are relatively expensive; polycrystalline solar panels have a lower cost, but lower conversion efficiency compared to monocrystalline; amorphous silicon solar panels have the lowest cost, but the lowest conversion efficiency. The choice of which type of solar panel to use should be based on a comprehensive consideration of the actual situation.


2.Conversion efficiency of solar panels

The conversion efficiency of solar panels refers to their ability to convert solar energy into electricity, usually expressed as a percentage. The higher the conversion efficiency, the more electricity can be generated per unit area. Therefore, when selecting solar panels, choose products with high conversion efficiency.


3.Installation location and angle of solar panels.

The installation location and angle of solar panels directly affect their power generation efficiency. Generally, solar panels should be installed in a position where they can receive sufficient sunlight and avoid being shaded. At the same time, the installation angle should be determined based on the local latitude and seasonal changes to maximize sunlight reception.


4.Maintenance of solar panels

Solar panels need to be regularly cleaned and maintained during use to ensure their power generation efficiency. When cleaning, first use a soft brush to remove dust and debris from the surface, and then rinse with clean water. During maintenance, regularly check whether the connection wires of the solar panel are loose or corroded and replace them in time.


When purchasing solar panels, choose reputable brands and manufacturers to ensure their quality and after-sales service. At the same time, make a reasonable selection based on actual needs and budget to achieve the best power generation efficiency and economic benefits.

1. What is a Solar Controller?

A solar controller, also known as a charge controller, is a device that regulates the amount of charge that is sent to the battery from the solar panel. The controller ensures that the battery is not overcharged or undercharged, which can damage the battery and reduce its lifespan.
A solar controller works by monitoring the voltage of the battery and the solar panel. When the battery voltage drops below a certain level, the controller will allow more charge to be sent to the battery. When the battery voltage reaches a certain level, the controller will reduce the amount of charge that is sent to the battery. There are two main types of solar controllers: pulse width modulation (PWM) and maximum power point tracking (MPPT). PWM controllers are the simpler and less expensive option. They work by turning the solar panel on and off to regulate the amount of charge that is sent to the battery. MPPT controllers are more advanced and efficient. They work by constantly adjusting the voltage and current to ensure that the solar panel is operating at its maximum power point.
To build a 2000 watt solar power kit, you would need the following: solar panels and mounting hardware, an inverter, batteries, wiring and control systems, charge controllers and other accessories. You should also consider additional elements such as back-up generators and energy efficient appliances.
A 2000 watt solar panel can run a variety of household appliances, including a refrigerator, washing machine and clothes dryer, a dishwasher, lights, heating and cooling systems, and more. Depending on the size and efficiency of the appliances, it could even power an entire home.
Types of batteries in solar systems, their advantages and disadvantages, and how to choose them. In solar energy systems, batteries are critical equipment for storing solar energy. Common types of batteries used in solar systems include lead-acid batteries, nickel-iron batteries, and lithium-ion batteries. Different types of batteries have their own advantages and disadvantages, as follows: 1.Lead-acid batteries: Lead-acid batteries are the most widely used batteries in solar systems due to their relatively low cost and ease of maintenance and replacement. However, their energy density is relatively low, their lifespan is relatively short, and they require regular maintenance. 2.Nickel-iron batteries: Nickel-iron batteries have a higher energy density, longer lifespan, and are less susceptible to damage from overcharging or overdischarging. However, they are relatively expensive and heavy, and require special installation brackets. 3.Lithium-ion batteries: Lithium-ion batteries have high energy density, long lifespan, and are lightweight, and do not require regular maintenance. However, they are relatively expensive and require special charging and discharging management. When choosing a battery, several factors need to be considered: 1.Capacity: Choose a battery with a suitable capacity according to the amount of solar energy to be stored and the electricity demand of the load. 2.Working temperature: Consider the ambient temperature of the solar system and the applicable temperature range of the battery, and choose a suitable battery. 3.Cycle life: Choose a battery type and brand that is suitable for the required service life. 4.Cost: Choose a battery type and brand that is suitable for your budget. In summary, choosing the right battery for your solar system requires considering multiple factors, including capacity, working temperature, cycle life, and cost. When choosing a battery, make a reasonable choice based on your actual needs and budget.
