How Do Home Solar Panels Work

The home use solar panels to convert sunlight into electricity using the photovoltaic effect. It consists of many solar cells made from a semiconductor material layer. Normally, this semiconductor material is silicon. Let’s learn how the home solar panel system works.

Photovoltaic Effect

The photovoltaic effect is a phenomenon in which semiconductor materials produce electrical energy under light. When light strikes the surface of the solar panel, the energy of the photons from the sunlight is absorbed by the semiconductor material, causing electrons in the semiconductor material to be excited and jump to high energy levels. In this way, an electron and a hole pair are created.

The Action of The Electric Field

There is an electric field inside the solar panel. It is usually made up of two different types of silicon. The doping of one type of silicon causes its electrons to lose excess electrons and become a “positive charge” region (P-type). The doping of the other silicon causes it to gain excess electrons and become a “negatively charged” region (N-type). An electric potential difference, or electric field, is formed between these two regions.

Electron Flow

Under the light, the free electrons and holes generated by the photovoltaic effect will begin to flow under the action of an electric field. Free electrons flow from the N-type region to the P-type region, and holes flow from the P-type region to the N-type region.

Current Generation

As electrons and holes flow, metal wires on the solar panel collect them, creating a current loop. In this way, photovoltaic panels convert light energy into electricity.

Direct Current Can Be Output

The electricity output of solar panels is direct current. But, most household devices and appliances are powered by AC currents. So, home solar panels usually need to be equipped with inverters to convert direct current into alternating current for home use.

How Much Do Home Solar Panels Cost

The price of solar panels for home use varies depending on several factors. Including the type of panels, specifications, capacity, brand, region, and installation costs. In general, the price of solar panels is determined by several major factors.

Panel Type

Types of solar panels include monocrystalline silicon, polysilicon, and thin-film cells. Monocrystalline silicon panels are more efficient, but the price is relatively high. Polycrystalline silicon panels are moderately priced. Thin film panels are relatively cheap.

Specification And Capacity

The size and capacity of a solar panel determine the amount of electricity it produces. In general, the larger the panel’s capacity is relatively higher but also can provide more power.

Brand And Quality

Well-known brands of solar panels usually cost more. But it is more guaranteed quality and performance. The purchase of high-quality panels can ensure its long-term stable operation and reduce maintenance costs.

Regional Difference

Factors such as the degree of competition in the solar market in different regions and government subsidy policies affect the price of solar panels. Some regions may enjoy more subsidies or incentives, which reduces the actual buying cost of solar panels.

Installation Cost

Solar panel installation costs include design, installation, and connection. Installation costs vary depending on the circumstances of the home. For example, roof structure, installation location, number of panels, etc.
