These cause harmful effects not only on humans, but also on the environment. Another problem is the supply and sanitation of water. The supply is becoming limited especially in rural areas and the sanitation is not being assured. In this research paper, the uses of solar energy and water as alternative sources are discussed. This research implemented solar electricity and water filtration systems for home use. Through these systems, the user can save a minimum of 20% of specific electricity wattage and save a certain amount of filtered water depending on the amount of rainwater collected. The materials used are Solar Panel, AGM Battery, Grid-tie Inverter, Charge Controller, Reverse Osmosis System, LCD, gizDuino+, ATMEGA 324P, and various components like resistors, transistors, and wires that made up the monitoring system’s circuit.

To address these problems, the group decided to design a system which includes the use of solar energy and rainwater. The system that the group is going to design and implement makes use of solar panel which helps in reducing the use of and saving electricity and water filter which also helps in minimizing water consumption, saving water and purifying and filtering rainwater [1]. On one hand, the solar panel is becoming widely used in commercial infrastructures, schools, and even residential areas. With the use of solar panels, sunlight can be converted into electricity [2]. This approach is very efficient in energy conservation and at the same time, it is environment-friendly because no process of burning is involved [3]. According to studies, using solar energy could save about 15% - 20% of energy. This will not only reduce the expenses of the homeowner but also reduces the harm to the environment done by the steam powered generator. Revised Manuscript Received on July 17, 2019. Aaron Don M.

Unlike the source from current power supplies, the energy source from the sun is completely renewable. This system is called solar power system [4]. On the other hand, the usage of reverse osmosis filtration system is also becoming helpful because of its function which filters tap or rainwater. By installing the apparatus, rainwater can be filtered into clean water. This water filtration system helps in saving money for the homeowner and at the same time, it also helps in conserving water [5]. Combining the two aforementioned systems, a smart house will be developed. This smart house is a system aimed to help homeowners in conserving electricity and water. A monitoring system is used to monitor the overall functions of both systems. Its database can be in the pattern of this research [6]. II. SOLAR POWER SYSTEM The main objectives of this research is to implement a solar electricity and water filtration system for home use while the specific objectives are a) To design and assemble a water filtration system that will be able to filter rain water into utility water b) To use the Reverse Osmosis process for water treatment c) To create a monitoring system for the solar electricity and water filtration system to allow the user to track the level of water and the amount of charge stored in the battery. The solar power system comprises of the following: 100-watt solar panel, AGM and car batteries, grid-tie inverter, and MPPT charge controller. The solar panel is the one responsible for gathering solar energy from the sun and converting it to electricity. For optimization purposes, Spatial Processing, Rough Set Theory and Neural Network can be used [7,8,9,10]. The 100-watt solar panel is used in this project. The AGM battery is used and is the one responsible for storing the gathered energy. If the gathered energy will be used immediately, it will then be supplied to the appliances using a charge controller [11]. The grid-tie inverter converts the collected energy in DC into a clean and stable sinusoidal alternating current which is then applied directly to commercial or local electrical grids. It usually supplies a stable sine wave current. The MPPT charge controller matches the output of the solar panel to the battery voltage level. It controls the output of the solar panels and protects the battery from damage due to overcharging [12].
