The very basics of a solar system
This is where it all really starts
What is a Solar System Kit
A basic electrical solar system is designed to convert sunlight into usable electricity through a series of interconnected components. The system typically starts with solar panels, which are made up of photovoltaic (PV) cells that capture sunlight and convert it into direct current (DC) electricity. This DC electricity then flows to an inverter, which converts it into alternating current (AC) electricity, the standard form used by most household appliances and electrical systems. The amount of electricity generated depends on the size and efficiency of the solar panels, as well as the amount of sunlight available.
Additional components in a basic solar system include a charge controller, batteries, and a mounting structure. The charge controller regulates the flow of electricity to prevent overcharging or damage to the batteries, which store excess energy for later use, such as during nighttime or cloudy days. The mounting structure holds the solar panels in place, often angled to maximize exposure to the sun. Together, these components create a sustainable and renewable energy system, reducing reliance on traditional power sources and lowering electricity costs.
Simple Solar Explained
This video explains how solar works in simple terms and then goes through the components one at a time.
Solar Panels
Solar panels are a fantastic way to harness renewable energy from the sun! They work by converting sunlight directly into electricity using photovoltaic cells. These panels can be installed on RV, Camper, and Home rooftops, in small or large arrays (Groups), portable and foldable, or even directly into products. They come in various sizes and powers (wattages) and can be connected in different configurations to meet your needs.
Solar Charge Controler
A solar charge controller is a key component in a solar power system. It regulates the voltage and current from the solar panels (PV) to your battery. Its main functions are to Prevent Overcharging, Prevent Deep Discharge, Optimize Charging, and Protect the System.
There are two types of controllers: PWM (Pulse Width Modulation) and MPPT (Maximum PowerPoint Tracking). Both have advantages and disadvantages, but most systems use MPPT.
Batteries for Solar Use
A solar battery stores the energy generated by your solar panels for use when the sun isn’t shining, like during the night or on cloudy days. If using a Flooded or Sealed battery (like a Car Battery), it is best to use a “Deep Sysle” battery instead of a Started Battery. While they both look like a typical “car” battery, some differences exist.
A Deep-cycle battery is designed for prolonged discharging and recharging and provides steady power over an extended period. A Starter battery is designed to deliver a large burst of power to start a combustion engine. Once started, an alternator takes over the electrical duties.
Lithium Batteries are ideal for applications where long-term performance, efficiency, and low maintenance are critical. They used to be more expensive upfront but are now very competitive with Lead-Acid batteries and offer greater lifespan, efficiency, and compactness.
12v Inverter
A 12V inverter is a device that converts 12-volt DC (direct current) power into 120-volt AC (alternating current) power. This is useful for powering household appliances such as TVs, Coffee Makers, Computers, and electronic devices from a 12V battery, such as those found in cars, RVs, boats, or solar power systems.
Pure Sine Wave Inverters produce a smooth, clean 120V AC waveform that closely resembles the power supplied by the grid. This makes them suitable for sensitive electronics and appliances like computers and audio/video equipment. Modified Sine Wave Inverters are less expensive and produce a rougher, stepped waveform that is more suitable for simpler devices such as lights, fans, and small appliances.
Battery Shunt/Monitor
The shunt is used to monitor and measure the flow of electrical current within the system. It is placed in-line (series) of the negative battery cable. As current flows through the shunt, a small voltage drop is generated, which can be measured to determine the current’s volume. This data is crucial for accurately tracking battery charging and discharging rates, ensuring the system’s efficiency and preventing overcharging or deep discharging of the battery. Solar battery shunts commonly use a digital display or BlueTooth device to provide real-time insights into the system’s performance, enabling better management and optimization your systemand usage.
Terminal Fuse Block
A terminal block is a device used to connect multiple electrical wires securely within a circuit. It serves as a central connection point where wires can be joined, separated, or distributed while maintaining a neat and organized setup. A terminal fuse block is a specialized component that combines the functionality of a terminal block with a fuse holder, providing a safe and organized way to connect and protect electrical circuits.
