Composition analysis of the whole house solar energy system of one's own family

In the eyes of many people, the cost of installing a whole-house solar system in a family is relatively high, but in fact, most of them only understand one-sided content. In fact, the initial investment cost of the photovoltaic power generation system is high, but the later operation cost is low. Therefore, if the long-term benefits are considered, the photovoltaic power generation system still saves money.

The whole house solar system includes photovoltaic power generation components, batteries, inverters, cables and other equipment and materials. There are construction costs and transportation costs. The service life of photovoltaic power generation systems is generally 25-30 years. Because the energy source of the photovoltaic power generation system is sunlight, basically no waste and residues are generated during the operation period, so the maintenance cost is very small.

The power generation of a whole house solar system is determined by photovoltaic modules. PV module capacity is the peak PV module output power under standard test conditions. According to each region, the situation of each user is different, resulting in small differences in the data. Therefore, the actual output power is determined by the amount of light. In addition, the output power of the photovoltaic power generation system should also take into account losses and aging.

The whole house solar system can generate electricity on cloudy and rainy days, but the power generation may be weakened by the weather. Therefore, when designing, you should consider the weather factor according to your needs.
