Sunshine houses have entered the public’s field of vision in recent years, and more and more people have new needs to build sunny houses. If you want to build a sunny house, you must first choose the location of the house, take into account the time of the sunshine in the year, and pay attention to the shadow position of the trees and adjacent buildings. For example, the east or the south side is suitable as the flower room, the west room must consider the sunshade and ventilation, and the north room is suitable for the small office.

Use the building’s terrace space to create a solar photovoltaic sun room that can both enjoy the sun and gain revenue. Instead of the original top glass structure of the house, it can not only solve the problem of too hot in the summer, but also ensure sufficient sunlight through the light transmittance of the photovoltaic panel, and also convert solar energy into electric energy, so that the function of the sun house can be upgraded. It has the high quality attributes of home leisure and investment management.

Solar module structure requirements: light transmission, waterproof and heat insulation. Traditional PV modules choose TPT and TPE as backsheet material, which is opaque and cannot meet the translucent requirements of sunny house. Moreover, the conventional aluminum frame is not easy to handle with water. Therefore, the general solar house components use double-sided glass solar panels or thin films solar panels.

1. Double-sided glass photovoltaic module means double-sided glass crystalline silicon solar cell module which has a slightly poor light transmittance, but can be supplemented by surrounding glass. The advantage of double-glass PV module is higher power generation, its efficiency is 18-20. %.

2. If there is a high demand for power generation and light transmission, CdTe thin film solar module is a better choice, which is various light-transmitting module. Moreover, the CdTe solar panel has uniform color, beautiful appearance and strong overall feeling, and is particularly suitable for use in buildings with high aesthetic requirements, and the efficiency can reach 13-15%.

3. If the requirement for power generation is not high and the requirement for light transmission is high, silicon-based thin film photovoltaic modules can be better, the efficiency of silicon-based thin film modules is 8-10%.

4. Choose CIGS photovoltaic panel within glass substrate.
