Have you ever thought about purchasing a bag of solar panels and plugging in your devices into them? They exist small appliances which can still be powered by direct current (DC) hence doing without the inverter used to convert DC to AC by the solar power panels.
Indeed, it is possible that solar panels can charge devices directly if the devices require DC power source. But most home products use AC and in such cases an inverter is required to convert DC power generated by solar panels into usable AC power.
However, it is still worthy understanding how this works and certain factors one must ask when it comes to different devices.
Solar panels are made to capture sun energy and transform it to electrical energy but the electricity produced is DC electricity. That is why almost all the electrical networks and most of the household devices are built for using AC power, it supplies more efficiently than DC over large distances and is safer in home usage. Thus, to interconnect the power produced by the solar panels to a normal home or a grid, an inverter is even essential.
We all need an inverter to make use of the solar energy in the homes, offices and other business premises. It operates in the manner of translating DC power provided by solar panels into AC power in considering the current tendency of electrical grids and home appliances. The conversion process also includes not only current type conversion, but also the rigorous subtraction and addition of certain voltage and current to make the energy meet certain safety and optimum use standards efficiently. Enhancement of this process is achieved through smart energy management systems present in the advanced inverters to output power related to real-time demand and supply.
Further, they are used to manage the power flow in the circuits and thereby protect electrical appliances and circuits from damages resulting from volatility of electrical power.
Using of direct sun energy systems for small gadgets is advantageous and friendly to the natural environment. Especially, appliances, which are designed for direct current (DC) power supply, can be powered directly using solar panels without conversion from DC to AC. These includes cell phone, portable fan, effective LED lighting, some type of camera, and personal electronics such as notebook computers.
For this reason, solar panels have to be matched with the right voltage to suit the equipment’s voltage rating. DC connectors together with portable solar chargers makes it easier hence can be used by anyone with no technical expertise. All these portable solar chargers are collapsible, small sized to make them easily portable for use when one is in the wilderness, or in cases of power failure, hiking, or camping among other uses.
Since the direct power is obtained without involving an inverter and AC conversion, the advantages are a higher efficiency. This is so because the energy losses which would ordinarily accompany the conversion of the currents from DC to AC are avoided. Thus, the specific power consumption of these devices is decreased, which increases the efficiency of daily electronic experience.
Using batteries, solar Panels and a functional charge controller is another method that is appropriate for environments where AC is not required. The integration of a charge controller in such systems cannot be overemphasized because it regulates the amount of power output from the solar panels into the batteries and protects the batteries from over-charging, or a rise in voltage that is possibly destructive to the battery life.
There are different types of charge controllers including; PWM charge controllers and MPPT charge controllers and the latter is more efficient in harness power from the solar energy depending on the lighting conditions prevailing at any one time.
This kind of charging is one of the best for small power usage, such as in RVs, boats, cabins, and other types of off-grid structures, as well as for large off-grid power systems, for which a reliable source of power is necessary. In these scenarios, as in those described above, the battery plays a central role of the system, accumulating the power obtained through the solar panel during the daytime for use at night or during a cloudy day.
The idea of a house completely powered by solar only has its advantages the biggest one being on the environmental front, however attempting it with out an inverter poses a lot of problems.
Most of the home appliances and the system found in today’s homes are intended to run on AC power. Trying to convert an entire house to DC compatible appliances may not only require replacing all these appliances with DC ones but also the electrical layout of a house, which can be very expensive.
However, the irregular or unpredictable nature of the source of energy in this case, aggravates the above problems. Wind and solar equipment generate electricity at the time of availability of wind or sunlight and are therefore not reliable except when combined with appropriate battery storage systems. These batteries would have to be sufficiently large to store enough power to power the household over nights and overly cloudy days. It also entails a complex monitoring or control system to address the resources to load and storage, energy when available.
As is apparent, it is entirely possible to power a home only with solar, however, solar home is usually integrated with solar panels and an inverter making it a more efficient, reliable and flexible power source.
Using solar panels devoid of an inverter serves the basic purpose of directly powering DC devices, more environmentally friendly and possibly cheaper. Nevertheless, it is necessary to realize these limitations in order to apply solar power into one’s home energy system most adequately. For most homeowners, inverters will remain core components of the solar systems, as they guarantee that the solar power produced can be utilised within numerous home appliances.
