Minahasa wooden houses are an inseparable part of Indonesia's cultural heritage. However, in this modern era, the challenge of maintaining cultural authenticity while introducing it into the technological era is increasingly pressing. This study aims to design a Smart Home System concept integrated with Solar Power Plants (PLTS) in Minahasa wooden houses to increase the selling value of the product. The purpose of this study is to identify the potential for integrating smart home technology and PLTS in Minahasa wooden houses and to develop a concept that combines traditional elements with modern technology. The research method that will be used is a literature study to understand the concept of smart home, PLTS, and the characteristics of Minahasa wooden houses. In addition, a descriptive research method through interviews will be carried out in collaboration with an industrial partner, CV. Jaya Tujuh Tujuh, to obtain data and examples of Minahasa wooden house products that will be used as a comparison in designing the concept. Thus, it is hoped that this research can contribute to integrating modern technology into Indonesia's rich cultural traditions, while increasing the competitiveness of Minahasa wooden house products in the market.

The typical Minahasa wooden house has various forms. In relation to the material, its characteristic is that the main material uses wood. In terms of house design, the typical Minahasa wooden house is made with a stilt house model that has a cavity underneath. The roof construction is pyramid-shaped. The concept of a wooden house model that has solar panels installed on the roof can be seen in the following picture.

To see the potential of electrical power that can be generated through the installation of rooftop PLTS, the sunny design simulator is used which can be accessed at https://www.sunnydesignweb.com/. The wooden house sample was taken in the woloan area where the wooden house sales display is. The sample calculation points as initial data can be seen in the following image.

As a consideration for the prediction of the need for electrical power usage in this wooden house, it is estimated that the annual energy consumption is 3000 kWh. The determination of this section is only an estimate, not a definite price. In reality in the field, the annual energy consumption value can be more or less. In Figure 5.3. Is a simulated rooftop PLTS system design. In the simulation it was determined that the Solar Panel used had a capacity of 200Wp. The installation of solar panels was only placed on the left and right sides of the roof. The results obtained with the existing roof area, the number of solar panels that can be installed is 30 units each with a total of 60 solar panels. The total capacity of the installed solar panels is 12kWp.
