Solar panels, solar heating and alternative energy sources are becoming more common in our homes. Solar energy is free and does not pollute the environment. But if you decide to set up a solar system, you should know how and what to buy. Alternative energy has long been not only environmentalists, but also the survival needs of all the inhabitants of the planet. If we use energy from wind, sun or water, not only to preserve the nature of any other pollution, but also to save using the free energy we take from nature. The Western world has long understood all the benefits of using solar systems that discharge the sun's free energy.
The electricity generated by the solar panels and flows to a device for controlling and charging the battery is stored in batteries which, in turn, maintain energy to the final consumer. The mode of production of electricity in the collected batteries must be able to use it, but transformed into electricity suitable for household appliances. The device for this purpose is called an inverter and its performance depends on how much consumers can use at home.
SOLAR PANELS
The principle of operation of solar panels based on the capacity of the material during the burning of the slight voltage difference occurs, causing a direct current flow. Solar panels are made of semiconductor materials and their efficiency depends on them. We have single-film thin-film solar panels and solar panels, and all manufacturers offer a 25-year warranty. When buying, it is important to know how strong you need power outages and solar panels, because the price depends on the strength. You should also pay attention to the shape and size of the panels and panels where you want to ask. Be sure to ask the store how to set up the availability of a suitable roof rack. The panel is placed on the roof of a house or a place that is not in the shade most of the day and certainly in the south. The work of solar panels depends on light, not heat, so in winter you can expect electricity, but in a smaller amount, because the sun's rays fall at a smaller angle.
CONTROLLED
Controllers are devices placed between the solar panel and batteries, and their main task is to control the charging system, ensuring that there is no overcharged battery. When purchasing this device, you should pay attention to the maximum input current, as the item is associated with a cost. We need to make sure that the controller contains an integrated temperature control, because the maximum capacity of the battery depends on the temperature of the environment in which it is located. The controllers are designed for itself and for output tasks. It is important to never connect to the solar panel directly to the battery.
BATTERY
As in a car, the battery is used to store energy from sunlight collected by a solar panel. If you only use electricity on weekends, it is important that their capacity persists for at least three days, and the panels will charge the batteries while you are away. The batteries are made with 12 or 24 V, and the prices are related to capacity. There are two types of batteries on the market for this purpose. Starter batteries and car batteries. They are characterized by high power in the initial charging stage, but have a smaller number of charging and discharging cycles during life. Solar batteries are characterized by equal force for the entire charge and multiple charging and discharging cycles. If you use a solar system for occasional use (weekends, holidays), then the starting battery will be enough, while daily use is certainly recommended by solar batteries.
INVERTER
Want to use household appliances will also need an inverter. The task is to supply the DC voltage of the 12 or 24 V inverter from the battery to an alternating voltage of 220 V, so that you can use devices such as radio, TV, water pump, energy saving lamps, computer, refrigerator or less standard. When buying appliances, be careful of their input voltage, they must be in accordance with your solar system. When buying a power inverter, make sure that the inverter needs fuses that protect the rest of the system from short circuit and overload. These devices always connect directly to the battery. The 220V AC voltage from the inverter can be life-threatening.
The solar system is limited by the energy source, unlike the electricity grid which can be considered an unlimited source. What the
